The Standard Assessment Procedure (SAP) score is an important part of any new build project which assesses how much energy a dwelling will consume. We design our products to score as highly as possible to maximise your SAP rating and to ensure the highest possible energy efficiency for the homeowner.

Our new 36kW Assure boiler has an excellent SAP rating and is hands down the best choice for new build.
