SAP Calculation

We do not currently offer this service.

We have several years experience and are fully qualified to undertake SAP Calculations to satisfy building regulations requirements in Scotland, England & Wales.

SAP Calculations assess the energy performance of the whole dwelling and return a DER (Dwelling Emission Rate) figure that must be lower than the TER (Target Emission Rate) figure. These figures are expressed in terms of kgCO2/m2/yr. A SAP Calculation will take into account the performance of central heating, the thermal performance of doors, walls, floors, roofs & windows.

We are able to offer comprehensive remedial advice in the event of initial non-compliance.
