SAP Calculations 

SAP calculations are a way of rating and comparing the energy and carbon performance of different homes. By making standardised assumptions on consumption trends and behaviour, like-for-like comparisons are able to be made. 
SAP calculations predict how much energy a dwelling is likely to consume and how much carbon dioxide the property is likely to output. The assessment gives ratings on the energy efficiency of the building, the energy consumption and the environmental impact. 
In accordance with part L1 of building regulations a SAP calculation must be provided to Building Control for a new or extended dwelling. 
We can provide SAP calculations from design stage Predictive Energy Assessment (PEA) to as built EPC. 
Hallfarm Surveys provide SAP Calculations across the Yorkshire region, including Castleford, Leeds, Pontefract, Knottingley, Wakefield, Selby, Harrogate & York.
