Landlord EPC Rules 2030

Minimum Energy Efficiency Standards (MEES) set the minimum EPC rating you can legally let a property at, under the Energy Efficiency (Private Rented Property) Regulations 2015. The rules are tightening: EPC E today, rising to EPC C from 1 October 2030. Here's exactly what applies now and what's coming.

The rules today (in force)

• Minimum rating: EPC E for all tenancies (since 1 April 2020; new lets since 1 April 2018), per the official MEES landlord guidance.
• Cost cap: £3,500 (inc VAT) — if you can't reach E within that spend, you can register a high-cost exemption on the PRS Exemptions Register.
• Maximum penalty: £5,000 per property (up to £2,000 for letting a non-compliant property under 3 months, or £4,000 for 3 months or more, plus other components).

The 2030 standard (confirmed policy)

• Single deadline: all tenancies — new and existing — must comply by 1 October 2030, confirmed in the government's response on privately rented homes and the Warm Homes Plan. The earlier phased 2028/2030 approach has been dropped.
• £10,000 cost cap (inc VAT) per property, over a rolling 10-year period. Qualifying spend counts from 1 October 2025, and most third-party/grant funding counts (except Boiler Upgrade Scheme money).
• Low-value adjustment: for properties worth under £100,000, the cap is 10% of the property's value.
• 10-year exemption: if the property still falls short after £10,000 of spend, register a cost-cap exemption valid for 10 years and continue to let.

How 'C' will be measured

From the reformed Home Energy Model (expected H2 2027, per the GOV.UK HEM consultation update), compliance is expected to be a dual-metric test — a primary fabric-performance standard plus a secondary heating or smart-readiness standard — rather than the single A–G rating used today. Legal analysts have set out how the reformed metrics interact with MEES.

Exemptions

• Cost cap — all relevant improvements made (or the cap reached) and the property still falls short.
• Consent — a tenant, lender or planning authority withholds required consent.
• Devaluation — an independent surveyor confirms works would reduce the property's value by more than 5%.
• Wall insulation — where the only remaining measure could damage the property fabric.

All exemptions must be registered on the PRS Exemptions Register with supporting evidence — the official evidence requirements list exactly what each exemption type needs. See our what is an EPC and how to improve your rating guides to plan the work.

What to do now

1. Get an up-to-date EPC and recommendations report for each property — check what's on file at gov.uk/find-energy-certificate, and see our guide to getting a new EPC.
2. Prioritise low-cost, high-impact measures — insulation first, then heating and controls (see which upgrades move the needle most).
3. Keep evidence of qualifying spend from 1 October 2025 to count toward the cap.
4. Check grant eligibility: the Boiler Upgrade Scheme (England & Wales), the Warm Homes: Local Grant (England, tenants must qualify), and ECO4 before it closes on 31 December 2026. (The Great British Insulation Scheme closed on 31 March 2026.)
