MEES 2030: the EPC C rule every landlord needs to plan for
The Minimum Energy Efficiency Standard sets the lowest EPC rating you can legally let at. It is rising from E to C — new tenancies from 2028, all tenancies from 1 October 2030. Here is what that means, and how to get ahead of it.
Two separate things are in motion. One is the minimum rating a landlord must hold. The other is what an EPC measures in the first place. They are often muddled together, so here they are apart.
The minimum goes from E to C
E is the minimum for a domestic let in England and Wales today. The government confirmed in January 2026 that this rises to C — for new tenancies from 2028, and for all existing tenancies from 1 October 2030. A spending cap of £10,000 per property applies, and penalties for letting below the standard run to £30,000.
A C reached before October 2029 stays valid
Certificates last ten years. A property that reaches C before 1 October 2029 is treated as compliant until that certificate expires, which is a real argument for finding out where you stand now rather than in 2029.
RdSAP 10 already changed the survey itself
The assessment method behind domestic EPCs was overhauled from mid-2025 — the biggest revision since EPCs began. It asks for more detail on wall construction and insulation, and every window now has to be measured individually rather than sampled. That is why a proper visit takes 30 to 45 minutes and why photographic evidence matters.
The single A–G rating is being replaced
The single headline letter is being dropped in favour of four separate measures: fabric performance, heating system, energy cost and smart readiness. This was due in October 2026, but in March 2026 the government pushed the launch back to the second half of 2027, with a firm date to be agreed with industry. Reformed certificates keep the ten-year validity, and anything lodged now stays valid for its full ten years regardless.
Getting to band C, in order
Know where you stand
Book a domestic EPC to the current RdSAP 10 method. If it already reaches C before October 2029, that certificate keeps you compliant until it expires.
Get the cheapest route costed
Our EPC Improvement Plan models your actual property and ranks measures by band impact per pound — so you spend the £10,000 cap where it moves the rating, not where it doesn't.
Prove it before the deadline
Reassess once the work is done to lodge a compliant certificate. Landlords with portfolios can raise every property in one place — talk to us about the landlord route.
MEES questions, answered
Frequently Asked Questions
What is MEES?
MEES — the Minimum Energy Efficiency Standard — is the rule that sets the lowest EPC rating a property may legally be let at in England and Wales. Today that minimum is E. The government confirmed in January 2026 that it rises to C: for new tenancies from 2028, and for all existing tenancies from 1 October 2030.
When does the EPC C requirement start?
For a new tenancy, from 2028. For an existing tenancy that continues, from 1 October 2030. A property that reaches band C before 1 October 2029 is treated as compliant until that certificate expires — certificates last ten years — which is a real reason to find out where you stand now.
What happens if I let a property below the standard?
Penalties for letting a domestic property below the minimum run to £30,000. There is a spending cap of £10,000 per property on the improvements a landlord is required to make to reach the standard.
How do I find out my property’s rating?
Book a domestic EPC. Our accredited assessors survey the property to the current RdSAP 10 method and lodge the certificate on the government register, usually within 48 hours. From £49 — and our EPC Improvement Plan then maps the cheapest route from your current band to C.
Is MEES the same as the EPC reforms I’ve read about?
No — two separate things move at once, and they are often muddled. MEES is the minimum rating a landlord must hold. Separately, what an EPC measures is being reformed (the four-metric certificate), and the survey method itself was already overhauled to RdSAP 10 in mid-2025. This page is about the landlord minimum.
