In general terms, any relevant areas or facilities which serve the building should be included in the BREEAM assessment, regardless of whether they are also assessed under CSH/HQM.
Whilst CSH is a Department for Communities and Local Government (DCLG) scheme, it was developed by BRE Global and the requirements are generally aligned with BREEAM. This should not, therefore involve the duplication of work, but means that the same evidence can be applied to each scheme as appropriate.
