Flow control devices – Use of devices on individual sanitary fittings - KBCN1550
The intent of the requirement for flow control devices is to minimise the impact of undetected wastage and leaks from sanitary fittings and supply pipework.
The use of flow control devices on individual sanitary fittings alone does not, therefore, fully meet this aim.
Leak detection technologies – Compliance Principle - KBCN1566
Where it can be demonstrated that alternative water leak detection technologies can meet or exceed the capabilities of systems set out in the BREEAM guidance, subject to approval, these can also be considered compliant.
It is the role of the Assessor and the project team to provide evidence and justification in a compliance principle query (see
KBCN1555).
The following alternative solutions are currently recognised:
- Smart leak detection systems that are based on 'self-learning' (machine learning) to determine normal water use patterns are an acceptable alternative to systems that require manual pre-sets or manual programming.
Sanitary fittings used in religious practices – updated - KBCN1624
Such fittings should
not be included in the scope of this Issue. Please refer also to
KBCN0418
This guidance relates to fittings and facilities used in some religious practices, for example, for washing before prayer.
03 Nov 2023 - Updated. Previous guidance was incorrect and contradicted the approach outlined in KBCN0418
Shower with multiple shower heads - KBCN0855
To calculate the water use of a shower with more than one shower head, one of the following should be done:
- If all of the shower heads can be turned on at once, the flow rates should be added up.
- If the shower heads can only be used one at a time, the highest flow rate should be used

Using water from natural underground sources to offset water consumption - KBCN00094
Water from natural underground sources (for instance aquifer water accessed via boreholes) cannot be used to offset:
- NC / RFO: potable water consumption.
- IU: utility supplied water consumption.
A significant amount of water used for public consumption is already drawn from aquifers. Private boreholes may be drawing water from the same sources as public utility companies.
27-Mar-2024 - Title and text updated to broaden definition. Scheme applicability updated.
Washing machines and dishwashers – Water consumption data - KBCN1571
The water consumption data used to demonstrate compliance may be based on the lowest full wash cycle (i.e. not a pre-wash cycle, for example).
