Energy Performance Certificates – EPCs

Energy Performance Certificates give home buyers and sellers A to G ratings for their home’s energy efficiency and carbon emissions: ‘A’ being the best, and ‘G’ the worst. Energy Performance Certificates are required for both new dwellings and existing landlord/rental properties.

WARNING: There are two types of Energy Performance certificates (EPC’s) for domestic properties:-

  • On Construction (New dwelling) EPC
  • RDSAP (Existing Property) EPC

Please watch our services video

On Construction (new dwelling) EPC

This is for schemes that come under Building Regulation control and is applicable to newly constructed dwellings, conversion schemes or schemes that are classed as a Material Change of Use.

Sometimes Building Control May ask for Energy Performance Certificates on shemes that require Excess Glazing Calculations (Though this is rare)

When are Energy Performance Certificates required to be produced for new build or conversion works?

Once the work for new build is complete and all Air Testing, Code for Sustainable Homes requirements etc. have been carried out, the Energy Assessor will then produce “As Built”

DER-TER Calculations to make sure the scheme still complies with Building Regulations.

Once this has been done an Energy Performance Certificate can be produced.

Energy Performance Certifiactes for new and conversion schemes are based upon the compliance from Approved Document L1A and Approved Document l1B

If an RDSAP EPC is produced for any schemes under Buidling Regulations, it is invalid and cannot be used. 

 RDSAP (Existing Property) EPC

Energy Performance Certificates are required for existing properties which are for sale or rent. An EPC is valid for 10 years. Estate agents/letting agencies usually provide an EPC as part of their service, however you may save money going  direct to the Energy Assessor.

Please contact us if you have any questions regarding domestic or non-domestic Energy Performnce Certificates.
