The £3,500 cost cap and why exemptions exist
The MEES Regulations 2015 impose a maximum spending obligation on English landlords of £3,500 per property (inclusive of VAT) to achieve EPC E. If the cheapest combination of recommended measures that would bring the property to EPC E exceeds £3,500, the landlord is not required to spend more. A landlord who has spent £3,500 on improvements but the property remains below EPC E can register a high-cost exemption. Beyond the cost cap, specific barriers (third party consent refused; structural unsuitability; devaluation risk) justify their own exemption categories.
- £3,500 cost cap (England) — maximum landlord spending obligation to achieve EPC E
- Wales operates its own MEES regime — check the current Welsh cost cap and exemption framework
- All five exemption types require registration on the PRS Exemptions Register before letting
- Exemptions apply to the landlord — not the property; sale triggers new landlord obligation
- Register at gov.uk (search 'register an exemption private rented sector')
The five EPC exemption types — criteria and evidence
Each exemption type has specific criteria and required evidence:
- All improvements made (5 years): all relevant measures installed within the £3,500 cap; property still below EPC E; evidence: current EPC; receipts and invoices; contractor confirmation; landlord statement
- High cost (5 years): cheapest measure or combination exceeds £3,500 cap; evidence: current EPC; minimum 3 contractor quotes or qualified assessor report confirming cost exceeds cap
- Third party consent refused (5 years): mortgage lender; freeholder; planning authority; or tenant refused access; evidence: written refusal from the relevant party (lender's letter; freeholder's refusal; planning decision notice; tenant's refusal in writing)
- Devaluation (5 years): RICS-qualified surveyor confirms improvements would devalue property by more than 5%; evidence: RICS surveyor report specifying measures assessed and estimated valuation impact — property-specific and measure-specific
- New landlord (6 months): property acquired through distressed sale (probate; repossession; court order); 6-month transitional exemption from date of acquisition before MEES obligations fully apply
Registration process — register before letting
The exemption must be registered on the PRS Exemptions Register at gov.uk before the sub-standard property is let. A landlord who lets without having registered is in breach from the date the tenancy commences. The register is publicly searchable — anyone can check whether a property has a valid exemption. At exemption expiry (5 years or 6 months), the landlord must either improve the property to meet the standard or register a new exemption if circumstances remain unchanged.
Enforcement and proposed EPC C — planning ahead
Local housing authorities enforce MEES compliance. A landlord who lets a sub-standard property without a valid registered exemption faces a civil penalty of up to £5,000 per property, plus publication of the breach on a public register (visible to tenants, buyers, and letting agents). The Government has proposed raising the MEES minimum to EPC C (new tenancies from 2028; all tenancies by 2030 subject to consultation and legislation). Current exemptions registered under the EPC E regime will not automatically satisfy the proposed EPC C standard — landlords should model the cost of further improvements and plan for a higher proposed cost cap (up to £15,000 under earlier Government proposals).
- Up to £5,000 civil penalty per property per MEES breach — plus public register publication
- Proposed EPC C minimum (2028 new tenancies; 2030 all tenancies) subject to consultation
- EPC C cost cap expected to be higher than £3,500 — earlier proposals suggested up to £15,000
- ECO4 scheme provides government-funded grants for energy efficiency improvements in PRS
- Properties unable to reach EPC C with no viable exemption path may need to be sold
