Why it matters

What MEES (Minimum Energy Efficiency Standards) means for a landlord

MEES is the rule that makes the EPC rating matter. A property rated F or G cannot be let, or go on being let, without a valid registered exemption, and the penalty for letting it anyway can reach £5,000 per property. The step landlords most often miss is registration: an exemption you believe applies but have not registered is no defence. The minimum is due to rise to band C by 1 October 2030, so plan upgrades rather than exemptions where you can.

Worked example

How it plays out

Karen lets a house in Oxford rated F from 1 February 2026 without a registered exemption. The local enforcement authority, usually Trading Standards, learns of it and can serve a penalty notice: up to £4,000 for letting a sub-standard property for three months or more, with the total for the property capped at £5,000. She also cannot keep letting it lawfully until it reaches E or she registers a valid exemption. Getting quotes for loft and wall insulation before letting would have avoided all of it.

Common mistakes

Where landlords go wrong

  1. 01Believing an exemption applies without registering it on the PRS Exemptions Register.
  2. 02Assuming an old EPC still reflects the property after major work or changes.
  3. 03Treating the £3,500 spending cap as a target rather than a limit on what you must spend.
  4. 04Planning only for band E when government policy sets band C for 1 October 2030.

What to do

A short checklist

  • List every property rated F or G and decide this month: upgrade or register a valid exemption.
  • Get quotes for the recommended measures and keep them with the EPC.
  • Register any valid exemption and keep the reference.
  • Start planning for band C by 1 October 2030.
