About Us


How long does a Code for Sustainable Homes assessment usually take?
This depends on the type of development and how quickly the evidence required for each category of the assessment is provided by the Design Team. Assessments can be completed within a couple of months and others can take years. Once an assessment has been completed it will be submitted to the BRE for certification. This can take up to two weeks.
Will the assessor need to attend site?
Yes. Once the Post Construction assessment is underway it will be necessary for the assessor to attend a small number of properties, usually 10%, to take photographic evidence of what has been included in the assessment - including, but limited to, drying lines, energy display devices, white goods, bins, rainwater harvesting systems, renewable technologies and cycle storage.
How much does a Code for Sustainable Homes assessment cost?
Cost depends on the scale of the development. However, the BRE charge a certification fee of £37.50 per dwelling. For more details on cost, or for price enquiries, please contact us directly.
When should a Code for Sustainable Homes assessor be appointed?
Ideally the assessor should be appointed as early as possible so that the number of credits can be determined and changes can be made to the design if necessary. We would recommend that the assessor is appointed by RIBA Stage 2.
