SAP Assessments
New Dwellings, Conversions & Extensions
Thorough, accurate assessments every time
A SAP Assessment is required by Building Regulations to demonstrate that your new dwelling or extension complies with Part L of the Building Regulations.
In simple terms, a SAP Assessment confirms whether the dwelling has enough insulation and does not emit too much carbon as defined by the Regulations.
Depending on the classification of your development the way we assess this is a little different:
New Dwellings
For new dwellings built from scratch on a new plot, the SAP Assessment assesses the building versus a 'Notional' dwelling based on the same size, shape and orientation as the proposed building, but with the building specification (U-values, window area, heating system and efficiency etc.) made up of a set of reference values to determine the target fabric and emission rates your new dwelling should achieve.
Conversions
Where your new dwelling is categorised as a conversion e.g. from agricultural outbuildings or change of use from a commercial building, the SAP Assessment is only used to determine that the existing and new fabric elements (walls, floors and roof) comply with the minimum U Values required in Part L.
Extensions
SAP calculations are required for extensions if the proposed area of new glazing exceeds 25% of the total extension area. Building Regulations require this SAP Assessment to ensure that emission rates from the dwelling will be no worse following the addition of the extension. This is due to glazing having a lower thermal performance than insulated walls and roofs.
