For all new buildings other than dwellings the energy rating is referred to as the SBEM ratings/calculation.  The SBEM ratings/calculation is required at the design stage and at completion and must be submitted to us as the approved inspector at these stages.

The SBEM ratings/calculation does not need to be produced by accredited companies/persons but it is advisable that competent companies/persons produce the calculations to avoid errors being made that could lead to non-compliance.  SBEM ratings/calculations are required for extensions in certain circumstances where approved document L2A is applicable and this should be considered at the feasibility stage of design.

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