Get a SAP EPC for your residential development

A SAP or Standard Assessment Procedure calculation is a measure of the energy efficiency and CO2 emissions of a building.

It is a requirement for new residential developments, conversions, and certain extensions. SAP is also used to generate the Energy Performance Certificate or EPC.

If you’re planning to build dwellings, convert existing properties into dwellings, or expand and divide residential buildings, and you need a SAP EPC, PropCert’s well trained team of SAP energy assessors is here to help.

How are SAPs calculated?


Our SAP assessors do not need to visit your property or construction site to  do the calculations and report. Because of this, we would need documents like your architect’s plans and construction specification details.

During the SAP calculation, factors like your floor plan, cross sections, elevations, materials, window measurements, wall and floor specifications, and more are taken into account.

Once the calculation is completed, a rating from 1 to 100+ is generated. A rating of 1 means the building is extremely energy inefficient while a rating of over 100 means it exports excess regulated energy back to the power grid.

What do SAP ratings mean?

Higher ratings are attractive for buyers and renters because it means energy costs will be lower.

Receiving a lower rating is not necessarily a cause for concern. Our assessments include recommendations for improvement. And since the building is likely in the planning stage, you can still make adjustments to get a better energy efficiency rating by the time construction finishes.

Assessors assign an A to G rating to the structure, with A being the best and G being the worst. The average home in the UK has a D rating since the majority of the housing stock is over 50 years old.New homes, on the other hand, which are subject to the SAP assessment, are built with energy efficiency in mind and will receive a significantly higher rating, generally a B or even an A.
