MEES 2030: London Landlords Must Hit EPC C — Here's How

Minimum Energy Efficiency Standards (MEES) currently require rented properties to be EPC band E or above. Following the Warm Homes Plan government response published on 21 January 2026, the floor rises to EPC band C on 1 October 2030 for all in-scope tenancies — both new and existing. The previously proposed staged 2026 / 2028 dates were dropped in favour of a single unified deadline.

Existing band C ratings achieved on an EPC issued before 1 October 2029 remain compliant with the new MEES rules until that EPC reaches its 10-year expiry.

Failing to meet MEES means you cannot legally let the property. Civil penalties run up to £30,000 per breach per property — a significant increase from the earlier £5,000 ceiling.

The government has set a £10,000 per-property spending cap (or 10% of the property value, whichever is lower for properties under £100,000). Once a landlord has spent up to the cap on relevant energy improvements and the property still does not reach band C, a cost-cap exemption can be registered on the PRS Exemptions Register.

Improvements installed since October 2025 count toward the cap, as does third-party funding via government schemes (excluding the Boiler Upgrade Scheme).

Most D-rated London properties can hit C with one or two upgrades: high-efficiency boiler (worth 3–5 points), loft insulation top-up (2–4 points), LED lighting throughout (1–2 points), low-energy showerhead (1 point), TRVs on radiators (1–2 points).

EWI / cavity wall insulation is the heaviest hitter but most expensive. Often not needed if the property is already at low D.

Smart landlords are upgrading now — not in 2029. Insulation, glazing and heating contractor capacity will tighten sharply as the 1 October 2030 deadline approaches, and lead times of 6–9 months are expected in the final two years.

Cost-cap exemption: if all relevant improvements that can be installed within the £10,000 cap still leave the property below band C. Apply via the PRS Exemptions Register.

Listed building exemption: where improvements would unacceptably alter the character. Documentation required.

Third-party consent: where consent from a superior landlord, mortgage lender or local authority is reasonably required and refused.
