Verdict: Plan ahead
Band E: you can let this today. You are on the floor.
MEES sets today's floor at E, so an E is lettable now. Two things to watch: a renewal assessment under RdSAP 10 can score lower than your old certificate, and the confirmed 2030 rules raise the floor to C from 1 October 2030.
The rules behind the verdicts
Nothing in this tool is arithmetic; it is a rules lookup, and these are the rules, sealed to their instruments:
| Band | Today | From 1 Oct 2030 |
|---|---|---|
| A B C | Lettable | Lettable |
| D | Lettable | Works or exemption required |
| E | Lettable (this is the floor) | Works or exemption required |
| F G | Blocked without a registered exemption | Blocked without a registered exemption |
Current floor per the MEES Regulations 2015 SI 2015/962 and landlord guidance GOV.UK MEES; 2030 standard per the January 2026 government response Gov response Jan 2026. Selling and owner-occupation carry no minimum band.
What the verdict does not cover
- Scotland and Northern Ireland: MEES is an England-and-Wales regime; see Scotland and NI.
- Exemption eligibility detail: the six routes and their evidence are on exemptions.
- Commercial property: different track entirely; see commercial EPCs.
If the verdict sent you to work: improving the rating orders the measures, and EPC C by 2030 is the deadline you are working back from.
