The Code for Sustainable Homes (CfSH) is the national standard for the sustainable design and construction of new dwellings. By setting criteria for nine aspects of development - energy, water, materials, surface water run-off, waste, pollution, health & wellbeing, management and ecology - a 1 to 6 star rating is calculated, 6 being the 'best' and at least 3 being an acceptable standard.

CfSH is currently utilised on all Housing Association development, but planned to become more widely used. As an accredited assessor ashea calculates the rating which is than audited by Stroma Certification prior to registration and issue. The accreditation process comprises three stages - pre-assessment, design and as constructed - ashea can assist at all of these stages.

As a service to contractors ashea offers a 'free' pre-assessment calculation, and advice on practical cost effective ways of achieving Code ratings - at time of tender preparation. This detailed service is subject to being considered for appointment as Energy and Code Assessor should the Contractors tender be succesful. During the construction process ashea will provide input to enable the contractor to vary specifications taking into account all aspects.
