For new dwellings the energy rating is referred to as SAP ratings and this is required at the design stage and then at the completion stage.  The design stage SAP will indicate to us that the designs will or will not comply at commencement and the completion SAP will indicate if the built dwelling complies.

These SAP ratings must be produced by accredited companies/persons. SAP ratings are not required for extensions to dwellings unless this is necessary to demonstrate compliance if the design has excessive glazing for example.

If you require any further information, please do not hesitate to contact us here or call us on 01452 310880.
