About the certificate

How long does an EPC last? Ten years from the date it was lodged. A newer certificate replaces the older one on the register. Look yours up by postcode: how to check your EPC rating.

Can my rating change without any works? Yes. A new assessment can give a different result if the assessor finds features the last one missed, or if the method changes. Reformed certificates with new metrics are now expected in the second half of 2027 (Housing Today, press report).

Do I need an EPC to sell? Yes, a valid EPC is needed before you market the home (GOV.UK). There is no minimum band for selling.

Letting today

Can I rent out a band D home? Yes. The legal minimum for a private let in England and Wales is band E, in force since 1 April 2020 (GOV.UK guidance).

Which tenancies are covered? Assured, regulated and domestic agricultural tenancies, according to the GOV.UK guidance.

What are the fines now? Per property: up to £2,000 for letting below E for under 3 months, up to £4,000 for 3 months or more, up to £1,000 for false information on the exemptions register and up to £2,000 for ignoring a compliance notice, with £5,000 in total. A council can serve a compliance notice up to 12 months after a suspected breach.

The 2030 plan

Is band C by 2030 the law? Not yet. It is confirmed government policy: the response of 21 January 2026 sets one deadline, 1 October 2030, for all tenancies in scope. It still needs an Act of Parliament and then regulations, which the government aims to bring into force in 2027 (GOV.UK response). Details are on EPC C by 2030.

My home is already C. Do I need to do anything? Under the plan, a C issued on the current scale before 1 October 2029 counts until the certificate expires or is replaced.

Does the plan apply in Scotland or Northern Ireland? The response covers England and Wales. Scotland and Northern Ireland set their own rules; we have not covered them.

Do short-term holiday lets count? Not for now. The response says short-term lets will not be required to comply at this time and that the position stays under review.

What spending counts towards the £10,000 cap? Measures installed from 1 October 2025, the EPCs before and after the works, and third-party funding such as ECO4 and Warm Homes: Local Grant. Boiler Upgrade Scheme grants do not count.

What is the planned maximum fine? £30,000 per property per breach, set by the local authority.

Owners

Do homeowners have to reach band C? No. The minimum standards apply to privately rented homes. Owners see the rating when they sell or let.

Are there grants for owners? The Boiler Upgrade Scheme pays £7,500 towards an air source or ground source heat pump in England and Wales (GOV.UK). Other help depends on income and where you live; see how to improve an EPC rating.
