Residential EPC
We arrange an Energy Performance Certificate for your home, carried out by an accredited domestic energy assessor. The EPC is lodged on the government register and rates the home from A to G, with recommended improvements.
When you need it
You must order an EPC before you market a home for sale or rent, and the buyer or tenant must be given a copy free of charge. An EPC is valid for 10 years from the date it was lodged, so check the government register first: the home may already have one.
Private rented homes that need an EPC must currently reach at least band E, unless a valid exemption is registered on the PRS Exemptions Register. The government has confirmed plans to raise this to the equivalent of band C by 1 October 2030, and has moved its reforms to the EPC itself to the second half of 2027. Neither change is law yet, so the current rules apply.
New homes get their EPC from the as-built SAP calculation, which is part of our energy and SAP service.

Questions
How long is an EPC valid?
Ten years from the date it was lodged, unless a newer EPC is lodged for the same property. You can check for an existing certificate on the government register.
What rating does a rented home need?
Private rented homes that need an EPC must currently reach at least band E, unless a valid exemption is registered. Plans to raise this to the equivalent of band C by 2030 have been confirmed by the government but are not yet law.
Are EPCs changing?
The government has announced reforms, including new headline measures on domestic EPCs, now planned for the second half of 2027. Until then, EPCs are produced and used under the current rules.
Can you help me improve the rating?
The EPC lists recommended improvements. If you are planning wider works, a retrofit assessment looks at the whole home in more detail.
