In short
Landlords in England and Wales must currently hold a minimum EPC rating of E to let a property. The government confirmed in January 2026 that all private tenancies — new and existing — must reach EPC C by 1 October 2030, with a £10,000 per-property cost cap. The current maximum fine is £5,000 per property; the government plans to raise this to £30,000 once new legislation passes. ECO4 and the Boiler Upgrade Scheme can fund qualifying upgrades.

Band E. Anything F or G is unlawful to let without a registered exemption.
The Minimum Energy Efficiency Standards (MEES) regulations have applied to all privately rented domestic properties in England and Wales since April 2020. Before that date, only new tenancies had to meet the band E threshold; since then, every existing tenancy has needed to comply too. The rules are set out in the Energy Efficiency (Private Rented Property) Regulations 2015.
Scotland operates separately under its own domestic Energy Efficiency Standard, and Northern Ireland has no equivalent landlord minimum standard. The bulk of this guide applies to England and Wales.
If your property is rated F or G and you don't hold a valid exemption, you cannot legally let it. Marketing it as available is itself a breach. Existing tenancies in F or G properties are also non-compliant — the regulation is not just about new lets.
The government confirmed in January 2026 that all private tenancies — both new and existing — must reach EPC band C by 1 October 2030.
The consultation on raising MEES to band C closed in February 2025, and the DESNZ response confirmed a single 1 October 2030 deadline applying to all private tenancies — both new and existing — with a £10,000 per-property cost cap. Final legislation has not yet been laid at time of writing (May 2026), so the exact statutory wording and the cost-cap figure could shift before commencement.
If your property is currently rated D, you have roughly two years from now before new tenancies need to meet the higher standard. Loft and cavity insulation, a modern boiler with smart controls, and LED lighting can typically lift a D-rated home to a C. Our how to improve EPC rating guide breaks down the specific measures and their typical impact on the score.
The move toward band C is the single largest regulatory change facing landlords this decade. Getting upgrades done before the rush — and before grant schemes tighten or close — is the editorial position we'd take. ECO4 closes December 2026, and the successor scheme's terms are unknown.
Under the current 2015 Regulations, the statutory maximum fine is £5,000 per property. The government's January 2026 proposals would raise this cap to £30,000 alongside the 2030 band C deadline, but that higher figure is not yet law.
The penalty structure under MEES is set by the local authority enforcing the rules, and the maximum totals reflect that several breaches can be stacked:
| Breach | Maximum penalty |
|---|---|
| Renting a sub-E property under 3 months | £2,000 per property |
| Renting a sub-E property 3+ months | £4,000 per property |
| Providing false information on the PRS Exemptions Register | £1,000 |
| Failing to comply with a compliance notice | £2,000 |
| Publication penalty (your name on the breach register) | Reputational, no cap |
For a single property held in breach for more than three months, that's £4,000. For a portfolio landlord with multiple non-compliant properties, the total can exceed £30,000. Local authorities can also publish details of the breach on a public register, which affects future lettings and lender views.
Enforcement has historically been patchy — Trading Standards and local authority enforcement teams are stretched — but Ministry of Housing data shows enforcement notices roughly doubling year on year since 2023. Treating MEES as a low-priority risk is no longer defensible.
The landlord. Tenants have no obligation to upgrade the property, and the cost cannot be passed to them.
Landlord pays for the EPC assessment
Typically £60 to £120. The certificate must be valid (issued in the last 10 years) before marketing the property.
Landlord pays for upgrades
Where the property falls below the minimum band, the landlord funds the works. The current cost cap is £3,500 (including VAT); the proposed band C cap will be £15,000.
Tenant benefits can fund the works
If your tenant claims Universal Credit, Pension Credit or other qualifying benefits, their status can trigger ECO4 eligibility for your property — funding the upgrades at no cost to you.
Landlord consent required for grant works
Tenants can apply for ECO4 on your property, but the works can’t proceed without your written consent. You retain control over what’s done.
ECO4 can fund insulation, a new boiler or a heat pump on your rental property at no cost. The eligibility checker confirms what applies in 2 minutes.
The tenant-triggered route is the under-used piece of the puzzle. A landlord with a tenant on Universal Credit, in a property rated D-G, can have a full insulation package and boiler replacement funded through ECO4. Read more on the ECO4 scheme rules for the full criteria.
Five exemptions exist, each requiring registration on the PRS Exemptions Register before they take effect.
Exemptions don't apply automatically. You must register each one on the PRS Exemptions Register and re-register every five years. An unregistered exemption offers no protection from a penalty.
The registered exemptions are:
Register each exemption on the PRS Exemptions Register with the supporting evidence. Most exemptions last five years and need renewing; some (like third-party consent refused) expire when the underlying condition changes. The temporary exemption for new landlords (6 months) is a holding period, not a permanent route.
ECO4 funds insulation and boilers for benefits-eligible tenants. The Boiler Upgrade Scheme funds £7,500 off a heat pump regardless of tenant status.
Best for
Landlords whose tenants claim qualifying benefits
What it pays
Full insulation, boiler replacement, sometimes heat pump
Main catch
Property must be EPC D-G; tenant benefit status drives eligibility
Runs until
December 2026
Best for
Landlords replacing gas/oil/LPG boilers with a heat pump
What it pays
£7,500 off an air source or ground source heat pump
Main catch
You apply via an MCS installer; tenant benefit status not required
Runs until
2030 under the Warm Homes Plan
The Boiler Upgrade Scheme is the one most landlords overlook. It doesn't require tenant benefits, it doesn't require a low EPC band, and £7,500 against a heat pump installation can make the economics work where they otherwise wouldn't. For a rural property currently rated E or F with oil heating, a heat pump under BUS often lifts the rating to a C in one step.
If your tenant claims benefits and your property is rated D-G, ECO4 is the priority — it can fund insulation, controls and a boiler at no cost. Apply before December 2026.
Apply for the high cost exemption if upgrades exceed the cap, but document the evidence carefully.
Properties with solid walls, single-storey rural buildings, or those with significant heritage restrictions can struggle to reach band C even with £15,000 of spend. The high cost exemption exists for exactly this scenario, but you need three quotes for the recommended works and evidence the total exceeds the cap. The exemption lasts five years and must be re-registered.
The other route worth considering: a fabric-first approach with solar PV and a heat pump can push some hard-to-treat homes from F to D or even C, particularly when combined with cavity wall insulation where structurally feasible. Our grants for EPC band C guide covers the upgrade combinations that produce the biggest jumps.
