Bamboo, cork and other non-timber forest products – Responsible sourcing - KBCN1768

Non-timber forest products, such as bamboo and cork should be responsibly sourced to minimise the environmental impacts and protect local ecosystems. However, as they are not timber or timber-based products, these fall outside the scope of the Prerequisite. Where such products are integrated into a building, they should, nonetheless, be assessed and included in the calculator under ‘Other materials’.

BREEAM Excel Tools - KBCN1755

The new BREEAM Platform now integrates all Excel-based calculator tools directly into the system for a more streamlined experience. Simply input your data, and the platform will automatically calculate and display the results.   Please note, this functionality currently applies only to BREEAM New Construction V7. 

BREEAM New Construction V7 – FAQs - KBCN1754

The FAQ webpage has been developed to provide early clarification and guidance on aspects of BREEAM New Construction Version 7 (NC V7). It is intended to address questions and highlight key changes from previous versions. Further guidance is provided within the published technical manual, and this will be supplemented by Knowledge Base Compliance Notes (KBCNs). To see the full list of FAQs, please refer to the Version 7 FAQs webpage

Campus or campus-type developments – Entrance to consider - KBCN1726

For assessments on sites with multiple buildings (e.g. education campus, business or industrial parks):

Purpose: To ensure fair assessment on large sites and to encourage the provision or location of amenities and public transport nodes within or at the periphery of the site. 
Note: wording update for clarification and including BIU

Capped gas supplies – Shell & core assessments - KBCN1818

If a capped-off gas supply is provided, this does not prevent credits from being awarded under criterion 1. The key requirement is that all heating and hot water systems designed or installed within the scope of works (the core services) must use non-combustion systems.

Clarification of ‘Embodied carbon benchmark comparison’ - KBCN1819

The embodied carbon benchmark comparison must always be based on the latest appropriate LCA stage that corresponds to the BREEAM assessment stage being pursued. The purpose of the benchmark comparison is to assess outcome-based embodied carbon performance, using data that is representative of the building at the relevant assessment stage.

Assessment stage requirements

Interim (Design Stage) BREEAM assessments

Final Post-Construction Stage (PCS) BREEAM assessments

If a PCS LCA is not undertaken, benchmark comparison credits cannot be awarded at final assessment, regardless of whether a technical design LCA was previously completed. This aligns with wider industry frameworks (e.g. RICS WLCA v2 and the UK Net Zero Carbon Buildings Standard), which anchor performance claims to as-built outcomes.

Clarification of ‘rural location’ in England and Wales - KBCN1824

A rural location is defined as any settlement with a resident population of fewer than 10,000 people, including rural towns, villages, hamlets and dispersed dwellings, as set out in the Government’s Rural‑Urban Classification (RUC).
To confirm whether a development is located in a rural location, enter the site postcode into: Web map for Rural Urban Classification (RUC) of Local Authority District Areas (LADs), England and Wales, 2024 | Open Geography Portal Only locations classified as rural within the RUC system are eligible. This includes areas designated as Majority Rural or Intermediate Rural.  

Compensating for habitat loss – Habitat type - KBCN1772

When compensating for habitat loss, any habitat type lost should be compensated for by the same habitat type. This is to ensure that it is capable of supporting the species affected by the habitat loss resulting from the development.

Credit requirement for an “Excellent” or “Outstanding” – Connection to district heating is a condition of Planning - KBCN1766

This KBCN applies when a project is required to connect to a district heating system as a condition of planning and this is preventing the project from achieving the number of credits required for a BREEAM Excellent or Outstanding rating. In these situations, an additional brukl.inp file must be generated for the actual building but with an alternative heating system, e.g., a heat pump, that demonstrates that the minimum standard would be achieved if the building didn’t have to connect to district heating. A technical query must be raised citing this KBCN and stating the minimum standard being sought with two brukl.inp file attached, one for the actual building with district heating and one with the alternative with an alternative heating system. Where the brukl.inp documents demonstrate that requirement to district heating is the only thing preventing the project from achieving the required number of credits, the technical team will confirm and arrange for the minimum standard to be waived. However, the number of credits awarded must be based on the building connected to district heating.

Daylight – Shading devices - KBCN1815

If any of the assessed spaces are expected to contain moveable shading device (such as blinds), then a dynamic modelling of their use should be included in the calculation for options 2 and 3, consideration should be made to the shading guidance in EN 17037 or IES LM-83-23, respectively. Option 1 does not have to include dynamic modelling of moveable shading devices. This will be updated in the next re-issue of the new construction version 7 schemes.

Ecological Clerk of Works - KBCN1771

If the project is using the comprehensive route to assess the ecological value of the site but the site has a low ecological value (for example, if it is mainly hardstanding), hiring an Ecological Clerk of Works may be an unnecessary cost for the developer. If the appointed SQE confirms that it is unnecessary to hire an Ecological Clerk of Works, then the requirements for the foundation route (nominating a biodiversity champion) can be applied, whilst still following the comprehensive route.  

Emissions from products – specialist paints and coatings - KBCN0872

Where a paint or coating falls within: then the paint or coating must be assessed. Specialist paints and coatings are exempted from meeting the VOC content and emission limits where there are no alternative products available that can perform the function, and still meet the emission limits. This must be clearly evidenced. 
30-Oct-2025 Applicable to HQM V6 and UKNCR V6.1
02-Oct-2025 Reference to 'VOC content' added and KBCN applied to UKNC V7 and INC V7 to clarify CN2.1 
27-Oct-2022 Wording clarified. New compliance principle added from UKNC V6.
10-Oct-2022 Title amended for clarity. Scheme applicability updated.
13-Mar-2020 KBCN amended to clarify exceptions and applicability.
16-Jun-2017 Content merged with KBCN0212.

ERRATUM – Enhanced Amenities - KBCN1817

The wording and approach to assessing ‘enhanced’ amenities in the technical manual is incorrect. The Aim of this assessment issue is, ‘To maximise the potential for people to choose public, active and lower-emission private transport by providing the site with convenient, sustainable options.’ In line with this intent, an ‘enhanced amenity’ should be referred to as an additional amenity, as it must provide an additional compliant amenity resulting from the development. If a development provides an amenity to replace an existing amenity, regardless of whether there is a qualitative enhancement or change of amenity type, this must be considered as an existing amenity. Furthermore, an additional amenity provided by the development may only be considered as such where there is a net increase in the number of compliant amenities resulting from the development. The updated guidance can be found below:   Option 10 - Additional amenities: Provide compliant additional amenities within less than or equal to 500 m of the building entrance. M4.2: Additional amenities Two or three points can be awarded for providing additional amenities ≤ 500 m via a safe pedestrian route. If additional amenities duplicate the services provided by existing amenities, this is still recognised. This is because duplicate amenities still create additional choices for users in terms of services offered and location. If a development provides an amenity to replace an existing amenity, regardless of whether there is a qualitative enhancement or change of amenity type, this must be considered as an existing amenity. A new amenity provided by the development may only be considered as ‘additional’ where there is a net increase in the number of compliant amenities resulting from the development. 2 points: at least one additional amenity 3 points: two or more additional amenities This will be updated in the next reissue of the technical manual.

Erratum – NCV7 – Ene 08 Installed controls - KBCN1812

There is a printing error in the following: UKNC V7 Ene 08 Table 6.18 INC V7 Ene 08 Table 43 The correct options for Installed controls for space heating are:
Control type Control functionality Points awarded
Heat generator output – heat pumps Multi-stage control (e.g. several on/off compressors) 1
Variable control (e.g. hot gas bypass, inverter frequency control) 2
  The technical manual will be updated accordingly in the next re-issue.

ERRATUM – Scope – Mixed-use developments and building types - KBCN1820

The wording and approach set out for assessing mixed-use developments in the technical manual is incorrect. Developments comprising of separate buildings with different function types cannot be assessed under a single assessment, unless they meet the conditions for Section 6 of GN20 (Separate buildings with a single, over-arching function). The updated guidance can be found below: Mixed-use developments and building types BREEAM defines different criteria and benchmarks for some assessment issues according to building type, function and use. A single building that includes different functions areas, e.g. office and retail, can be assessed under a single BREEAM assessment. Each area will need to comply with the relevant criteria for the building type. BREEAM credits that are awarded based on performance scales, such as Ene 01, Ene 02, Wat 01 and Mat 01, will be calculated on an area weighted basis. Buildings that are a mix of commercial and residential asset types, and developments which comprise of separate buildings with different function types, will need separate BREEAM assessments. Further guidance can be found in Guidance Note 20.

Flood Risk Assessment older than five years - KBCN1744

This sentence appears in the definition of 'Flood Risk Assessment': Where more than five years have passed since the FRA was carried out, evidence would be required to demonstrate that the basis of the FRA has not changed in that time. The requirement for evidence that the basis of the FRA has not changed where more than five years have passed is applicable only at Design Stage. It is not required at Post Construction Stage where a compliant FRA was undertaken at Design Stage and the development was carried out in accordance with that design.

Glare control – Modelling - KBCN1800

The ‘Glare control’ criteria do not require a specific methodology to be used to identify areas at risk of glare, and in most situations, a simple solar path analysis would be suitable. Alternatively, detailed hourly modelling methods, such as DGP and ASE, may be more appropriate. However, in either case, compliance cannot be assumed. Regardless of the methodology used, the modelling must be supported by robust reporting to demonstrate that each aspect of the criteria has been met.

Hotels and other short stay accommodation – cycle storage unit of measure - KBCN0676

The cycle storage requirement for hotels and other short‑stay accommodation is 1 space per 10 staff. Guests or visitors staying at the hotel are excluded from the calculation. Where a hotel includes on‑site facilities such as conference spaces, restaurants, or gyms, visitors to these facilities should also be included in the cycle-storage calculation: 1 space per 10 guests. Specific Note for Refurbishment and Fit Out International 2015 Table 36 in the technical manual incorrectly refers to “1 staff and 1 visitor, or 1 bed.” Please ignore this error and follow the guidance above.

Independent third party – clarification on the definition - KBCN1805

For the purposes of BREEAM, sister companies or parent companies cannot be considered as third parties.  To be classed as an independent third party, there must be no professional connection or relationship between the LCA consultant/energy assessor, or their company, and the verification body. The third-party verifier must be independent of the LCA or energy assessor and demonstrate impartiality (for general principles, see ISO 17029). To qualify as a third party, the verifier must belong to an organisation not involved in the project and must not provide advice to the project, as this could compromise their impartiality during verification.

Knowledge Base – Applicability of existing guidance to NC V7 - KBCN1757

We are in the process of undertaking a comprehensive review of existing guidance on the Knowledge Base for BREEAM New Construction to determine its applicability to New Construction Version 7, and the Knowledge Base will be updated in due course. In the meantime, if you wish to apply for a previous KBCN, please review the changes outlined in the Summary of Changes and compare the criteria in the technical manuals. If the criteria are the same, and you are satisfied that a previous New Construction KBCN is relevant to NC V7, you can follow this guidance. If there are differences in the New Construction V7 criteria, but you believe an existing KBCN can be applied, please submit a technical query on the webform to confirm this.

Late liaison and collaboration of project team with representative stakeholder - KBCN1814

Where it can be demonstrated that liaison and collaboration between the project team and the representative stakeholder occurred later than the early design stages (typically post-RIBA Stage 2 or equivalent), the criteria may still be met if a suitably qualified ecologist confirms that these late discussions have not compromised the site’s ability to achieve its optimal ecological outcome, in accordance with the mitigation hierarchy of action: 1. Avoidance. 2. Protection. 3. Reduction or limitation of negative impacts. 4. On-site compensation. 5. Enhancement considering the capacity and feasibility within the site, or where this is not viable, off-site.

LCA Concept Design stage submission before the assessment is registered - KBCN1437

In certain circumstances, it may be necessary for the design team to submit the Concept Design stage LCA before the BREEAM assessment has been registered. In such cases, please submit the LCA tool and associated files along with details of your situation as follows:

LCC – Competent person or Suitably Qualified Cost Consultant (SQCC) - KBCN1803

The definition of a competent person, or SQCC as named within HQM or BREEAM New Construction Residential, has been updated to provide further clarification and is now defined as set out below: An individual achieving all the following items can be considered to be ‘suitably qualified’ for the purpose of completing the LCC credits:
  1. Holds a recognised qualification for undertaking life cycle costing studies and/or a degree/postgraduate diploma or equivalent qualification in quantity surveying, construction economics or other construction-related subject.
  2. Has acquired substantial expertise through a minimum of three years relevant experience (within the last five years). The experience must clearly demonstrate a practical understanding of life cycle costing in construction and the built environment and show an ability to identify and demonstrate cost and performance enhancement measures.
  3. Is not professionally connected to a single manufacturer
A CV should be provided demonstrating their experience and knowledge against the above requirements.  

Legally harvested and traded timber – Examples - KBCN0956

The following examples are considered compliant for BREEAM: Legally harvested:
  1. Evidence of compliance with the UK government Timber Procurement Policy (see here, timber bought inside the UK only)
  2. FSC, PEFC, SFI or GiB certification
  3. Evidence of compliance with the EUTR (timber bought inside the EU only)
  4. Risk assessment/due diligence documentation demonstrating a low risk of non-compliance with the ‘legally harvested’ requirements given in the manual.
Legally traded:
  1. Evidence of compliance with the UK government Timber Procurement Policy (see here, timber bought inside the UK only)
  2. FSC, PEFC, SFI or GiB certification
  3. Risk assessment/due diligence documentation demonstrating a low risk of non-compliance with the ‘legally traded’ requirements given in the manual.
04-Dec-2025 - Examples updated to include Grown in Britain (GiB) certification. Previous reference to 'CPET' clarified as 'UK government Timber Procurement Policy'.
KBCN applied more widely to all relevant scheme issues in BREEAM and HQM

Meeting the minimum standard requirement – compliance when chain of custody is broken - KBCN1816

Where there is a broken chain in the last link between the purchase and delivery of certified timber from the supplier and the forwarding distribution of the timber to the site under assessment, such as where the timber has been delivered to a subcontractor or fabricator’s premises instead of direct to site (e.g. as part of a bulk order or where limited storage is available on site), compliance can still be achieved if a documented risk assessment confirms that there is low risk of mixing or substitution of certified and non-certified timber. Ways to demonstrate compliance: A. Verification that the subcontractor or fabricator only purchases and uses certified timber. There must be robust mechanisms in place to verify that all timber materials purchased and delivered originate from sustainably managed sources. This includes maintaining documented timber procurement policies and procedures that mandate certified timber orders and delivery checks. Comprehensive supplier details should be readily accessible for review upon request to demonstrate that all timber is certified. B. Where non-certified timber is handled/stored or sourced, that there are robust control measures in place to prevent any substitution or mixing of certified and non-certified timber at every stage of the process. Documentation demonstrating compliance should be maintained and made available upon request. Examples of appropriate control measures are listed below:
Control
Evidence required
Purchasing records All purchase orders, requisition notes, and contracts must explicitly specify the product details and confirm that materials are to originate from legal and sustainable sources.

Segregated storage of timber

 Site layout map, stock control processes and records to confirm that certified timber is stored away from non-certified timber.
Segregated delivery of timber to site - All timber must be thoroughly inspected and verified before shipment to confirm that it is correctly marked/labelled as FSC/PEFC-certified. - Delivery notes must be accurately maintained. - A second-party verification process to check tickets and stock, must be carried out upon site delivery to confirm certified status of timber.
Documentation Comprehensive documentation must enable independent assessors to trace any timber back to its sustainable source. This includes maintaining purchase records, goods-inward notices, stock records, and sales documentation such as orders and invoices.
The above is guidance and should not replace any local or national requirements for the sourcing of legally traded and harvested timber.

Operational waste requirement for catering – applicability - KBCN1162

The additional operational waste storage requirement for developments which include catering is generally only applicable where a commercial scale kitchen is present. Where the design team can justify that there will be no significant waste streams from a modest facility, such as a small cafe, selling only drinks and pre-prepared snacks, the additional waste storage area identified in the default values does not need to be provided to meet compliance. 
21-Jan-2026 Applied to NC V6 and V7 standards

Predicted operational energy performance score – Credit table update - KBCN1825

From 4th February 2026, the following credit table applies to Ene 02 in all BREEAM International New Construction V7 and BREEAM UK New Construction V7 assessments: *Alternatively meet the minimum EPRNC score specified for Excellent in Ene 01. **Alternatively meet the minimum EPRNC score specified for Outstanding in Ene 01. The OEPNC scores required for each credit boundary have been lowered on the BREEAM platform in response to assessor feedback and an internal review of credit attainment against our benchmark database. The table above supersedes: - Table 28 in BREEAM International New Construction V7 - Table 6.3 in BREEAM UK New Construction V7 For further guidance on Ene 02 and the achievement of OEPNC scores please refer to KBCN1751 - GN53 Energy modelling and predicted operational energy performance score in Ene 02. The above updated credit table will be included in the next reissue of the technical manuals

Scheme classification for residential projects (UK) - KBCN1225

Choosing the right scheme for developments is the starting point to ensure successful outcomes and value, in terms of quality and sustainability to building owners and for occupants of the building. In light of the release of Home Quality Mark (HQM) ONE we have reviewed the existing guidance around scheme classifications of new build residential buildings and have removed ‘GN03 – Scheme Classification – Domestic buildings’ from BREEAM Projects. When GN03 was written, the Code for Sustainable Homes (CSH) did not fully consider communal areas within residential blocks as part of the assessment. CSH was also not applicable in Scotland. GN03 was developed to clarify the differences between BREEAM Multi-Residential, CSH and EcoHomes, and when each scheme should be applied. There is now a clearer distinction between BREEAM Multi-residential and HQM and when these should be used. Ultimately, the determining factor for a scheme classification is now focused on the intent of the building and who is going to be the end user (as opposed to previous guidance which considered aspects such as percentage of communal areas, etc.). Broadly, if the building’s main purpose is for long term homes then Home Quality Mark is the correct scheme to use. Please use the following as guidance to identify the most appropriate scheme: UKNCR / Home Quality Mark (HQM) HQM has been designed with the occupant in mind. It assesses homes individually, but can also account for common areas associated with blocks of self-contained homes. HQM outputs (rating and indicators e.g. ‘my cost’, ‘my wellbeing’ and ‘my footprint’) are specifically aimed at those living in the home and are designed to better inform the occupant about the benefits of the home that they are purchasing or renting. An HQM project will meet one or more of the following criteria: Be designed to meet the function of a long-term self-contained home even though there may be some provision of communal facilities which can be used on a voluntary basis Be classified under Building regulations Part L1a (i.e. required to complete SAP assessments, although there may be some linked SBEM assessed spaces associated with the project) As such, HQM projects could be homes for sale, social housing or homes for rent (PRS and Built to Rent). They may also include some student and retirement/sheltered accommodation where the units are comparable to a normal self-contained flat/home. BREEAM Multi-residential For the purposes of BREEAM Multi-residential assessments, the term ‘multi-residential’ is used in the context of buildings that contain rooms for residential purposes alongside communal facilities for catering, leisure, care etc. These residential rooms would normally not have the full, self-contained functions of a home. This scheme usually covers more specialist residential care homes, student halls of residence, and other more communal accommodation. The scheme can cater for a small number of self-contained dwellings where these form part of a larger multi-residential development (e.g. on-site warden homes etc.). Under this scheme, the project is assessed on a whole building basis and as such does not seek to reflect the performance of individual residential units/rooms. A BREEAM Multi-residential project will meet one or more of the following criteria: Be provided for transient /non-permanent occupants Provide suitable accommodation for occupants requiring support from carers, wardens or similar Include shared living spaces Be classified under Building regulations Part L2a (i.e. required to complete SBEM assessments, but can account for some SAP assessed spaces where associated with the project) As a rule of thumb, if the building contains rooms rather than self-contained flats or homes, a BREEAM Multi-residential assessment would probably be most appropriate. We are aware of some confusion over the meaning of the term ‘multi-residential’ in this context and will be considering the use of term as part of the next review of the BREEAM Multi-Residential scheme. If you are unsure of the appropriate scheme classification for a particular project, please contact the BREEAM office before registering the project. 
11-Nov-2025 - Applicability to current UKNC, HQM and UKNCR confirmed

Security rating scheme – SABRE update - KBCN1767

BRE’s partnership with the Security Institute for SABRE certification ends on 31 August 2025. From this date, SABRE will no longer be offered by The Security Institute. The following guidance applies to projects targeting the security rating scheme criteria: Ongoing and Registered Projects Projects with existing or ongoing SABRE involvement may continue to pursue exemplary level credit using SABRE, provided that registration and certification activities occur before 31 August 2025. It is the responsibility of the project team to ensure that any SABRE-related assessments and certifications are completed and documented within the support window, in line with the BREEAM certification timeline. New Projects (post 31 August 2025) BRE is actively monitoring the market; however, no alternative schemes have been reviewed or accepted in place of SABRE. However, whilst the exemplary credit may no longer be available via the SABRE route, project teams wishing to achieve an improved level of security for a development may still seek to engage with a SABRE professional and integrate the principles of the scheme into their design. Key Implications: The Security rating scheme, exemplary credit remains available; however, assessors must: Acceptance of alternatives will be based on whether the proposed scheme demonstrates:    

Statutory Biodiversity Metric – Lowest percentage score - KBCN1773

When the Statutory Biodiversity Metric is used to calculate how many credits are awarded for an issue, the output with the lowest percentage score of the three outputs (habitats, watercourses and hedgerows) is used. In cases where the SQE has confirmed that there is no opportunity to enhance or create new habitat to increase the score, this requirement can be relaxed for the hedgerow and watercourse metrics (as these are usually those that are more difficult to compensate for). This exception is only applicable if on-site enhancement is used exclusively. If off-site enhancement is used, then the output with the worst score should be used.

Thermal comfort – Time-critical requirement - KBCN1801

The requirement for the full dynamic thermal analysis at detailed design stage, is set as this is the optimal stage to achieve the required sustainability outcome. When undertaken at a later stage, opportunities may be missed, options reduced or costs may become prohibitive. therefore the stipulated timeframes for such actions must generally be adhered to. However, if, due to specific circumstances or a non-standard the procurement route being used, the assessor can demonstrate that the aim of the criteria can still be fully met, despite the project having moved into a subsequent work stage, this will be accepted by BREEAM. In such cases, the assessor must justify and demonstrate that the ability to fully meet the aim of the criterion has not been compromised.

Verification of Security Needs Assessments/Security Risk Assessments - KBCN1770

Where the author of a Security Needs Assessment [‘Security Risk Assessment’ in BIU] does not meet the BREEAM competency requirements, compliance can still be achieved where the report is reviewed and verified by a qualified SQSS [‘Competent Person’ in BIU], who confirms in writing that it is accurate, appropriate and in line with industry best practice. In these circumstances, the SQSS or ‘Competent Person’ is expected to verify and take ownership of the report and accept professional responsibility for its content.

VOC credit issues – Clarification of scope - KBCN1797

The scope of these requirements does not include furnishings or moveable furniture, e.g. desks, seats or shelving. It includes fixtures and fittings that are integral to the building, such as kitchen units and toilet cubicles. However, bespoke fixtures, such as purpose-made items of fixed furniture, can be excluded, as the specified compliance testing is not appropriate for such items.
