EPC rules for landlords: the minimum rating and what may change

On this page

At the time of writing, a privately rented home in England must have an Energy Performance Certificate rated E or above before it can be let, unless the landlord has registered a valid exemption. The government confirmed in January 2026 that the standard is due to rise to band C, or its equivalent under a reformed EPC, from 1 October 2030, with a higher cost cap of £10,000. Landlords with an E or D rating now have a few years to plan works.

This guide sets out the rules at the time of writing from GOV.UK. It is general information and not legal, tax or financial advice. An accredited energy assessor can tell you what your property needs, and an accountant whether the cost is allowable against your rental income.

The rule today: band E

The Minimum Energy Efficiency Standard (MEES) regulations apply to most privately rented homes in England and Wales let on a tenancy and required to have an EPC. GOV.UK says landlords "can no longer let or continue to let" such a property if its EPC is below E, unless a valid exemption applies.

An EPC lasts 10 years. You need one before marketing the property, and prospective tenants must be able to see it. You can check whether a property already has a certificate on the government's register.

The cost cap and exemptions

Landlords are not required to spend more than £3,500 including VAT on improvements. GOV.UK lists six exemptions:

1. All relevant improvements made. You have installed the measures you can within the cap and the property is still below E.
2. High cost. Even the cheapest recommended measure would cost more than £3,500.
3. Wall insulation. Expert advice shows wall insulation would harm the fabric or structure.
4. Consent. A tenant, freeholder, lender or planning authority refuses consent despite reasonable efforts.
5. Devaluation. An independent surveyor shows the works would reduce the property's value by more than 5%.
6. New landlord. A six-month exemption from the date you became the landlord.

Exemptions last five years, except the new landlord exemption, and must be registered on the PRS Exemptions Register, which the public can search.

Penalties

According to GOV.UK at the time of writing, a council can impose a penalty of up to £2,000 for a breach lasting less than three months, up to £4,000 for three months or more, and an overall maximum of £5,000 per property. Penalties are published on the register too.

What is changing: band C by 2030

The government consulted in 2025 on raising the standard and published its response on 21 January 2026. At the time of writing it set out:

The response describes a new way of measuring performance, with a fabric standard first and then a choice between a heating system standard and a smart readiness standard. It said existing EPCs rated C would be treated as compliant until they expire, and that new legislation would be needed. Until that legislation is made, these are confirmed plans rather than law, so check the final rules before committing to large works.

How to improve a rating

The recommendations page of your EPC is the starting point: it lists measures in order and estimates the effect of each. The common ones are:

• Loft insulation topped up to current depths, usually the cheapest gain where there is a loft.
• Heating controls: a programmer, room thermostat and thermostatic radiator valves.
• A modern condensing boiler or, where suitable, a heat pump.
• Hot water cylinder insulation and pipe lagging.
• LED lighting throughout.
• Draught-proofing to doors, windows and loft hatches.
• Glazing: secondary glazing where double glazing is not allowed.
• Wall insulation: cavity fill where there is a cavity; internal or external insulation on solid walls, which is costlier and needs care with damp.

Have a new EPC done once the work is finished, since the old certificate will not reflect it.

Bournemouth's older flats

Much of Bournemouth's rental stock is in Victorian and Edwardian villas converted into flats, on the East and West Cliff, in Boscombe and around the town centre, alongside purpose-built blocks from later decades. Converted flats often have solid walls, high ceilings, large sash windows and electric heating, which can hold a rating down and make improvements harder.

Three points matter for these flats:

• The lease. Walls, windows and the roof usually belong to the freeholder. Insulating an external wall or changing windows may need the freeholder's consent, and a refusal can support a consent exemption.
• Conservation areas. Parts of central Bournemouth, Poole and Christchurch are conservation areas, where window and external changes may need permission.
• Heating. Replacing old storage heaters with modern high-heat-retention heaters and better controls is often the most practical step in a flat without gas.

If you are buying to let, read the EPC recommendations before you offer, and treat a D or E rating as a cost to price in. Our guide to buy-to-let in Bournemouth covers what to check, and the landlord legal checklist lists the other certificates.

Planning the next four years

With the band C date set for 1 October 2030 at the time of writing, a landlord with a D or E rating can plan rather than react:

1. Read the current EPC. Note the rating, the score within the band and the recommended measures.
2. Get advice on the reformed metrics once the government publishes them, since the measure of "band C" is changing.
3. Do the cheapest gains first. Insulation, controls and lighting cost less and can be done between tenancies.
4. Time bigger works around voids. Heating systems and wall insulation are easier with the property empty.
5. Keep receipts and reports. They support an exemption if the cap is reached, and they help with your accounts.
6. Ask about grants. Government and energy company schemes change, so check what is available before you pay.

How we help

When we value a property for letting we look at the EPC and the recommendations, and tell you whether it can be let as it stands. We can arrange a new assessment and contractors for the works. A rental valuation is the first step, and our letting agents page explains the service.
