Few topics cause as much confusion among landlords as Energy Performance Certificates. Headlines have talked about an “EPC C deadline” for years, but the rule you actually have to follow today is different — and the difference matters when you’re deciding whether to spend thousands on upgrades.
This guide separates what is legally required now from what the government has said it aims to do, using the official GOV.UK guidance on the private rented sector minimum energy efficiency standard (often called MEES).
Applies to: domestic private rented property in England and Wales covered by the MEES regulations.
The rule today: EPC Band E
The current legal minimum is EPC Band E. Since 1 April 2020, landlords of properties covered by the regulations can’t continue to let them if they’re rated F or G, unless a valid exemption is registered.
In practice, that means:
- you need a valid EPC for the property when you let it, and must give a copy to your tenant;
- the rating must be E or above; and
- if it’s F or G, you must either improve it or register an exemption.
An EPC is valid for 10 years, so check the expiry date on yours — a certificate that expires during a tenancy is a common oversight.
The £3,500 cost cap
If your property is rated F or G, you’re not expected to spend unlimited sums. GOV.UK sets a cost cap of £3,500 including VAT for self-funded improvements.
The key points:
- Energy efficiency improvements made since 1 October 2017 can count towards the £3,500.
- The cap applies when you are paying. If third-party funding (for example a grant) is available, the cap doesn’t limit what can be installed with that funding.
- If you’ve spent up to the cap and the property still can’t reach Band E, you can register a “high cost” or “all improvements made” exemption.
The six exemptions
GOV.UK lists six exemptions. All must be registered on the PRS Exemptions Register, and most last five years:
| Exemption | When it can apply | Length |
|---|---|---|
| All relevant improvements made | You’ve made every relevant improvement (up to the cap) and it’s still below E | 5 years |
| High cost | No relevant improvement can be made for £3,500 or less | 5 years |
| Wall insulation | Wall insulation would damage the structure of the property | 5 years |
| Consent | A required third party (e.g. the tenant, a lender or planning) refuses or attaches unreasonable conditions | 5 years |
| Devaluation | An improvement would reduce the property’s market value by more than 5% | 5 years |
| Recently became a landlord | You’ve recently become the landlord (e.g. certain circumstances of acquisition) | 6 months |
An exemption isn’t permanent. When it expires, you need to try again to improve the property or register a new exemption if you still qualify.
The penalties
Local councils enforce the rules and can issue fines per property. According to GOV.UK, the maximum penalties are:
| Breach | Maximum penalty |
|---|---|
| Letting a substandard property for less than 3 months | £2,000 |
| Letting a substandard property for 3 months or more | £4,000 |
| Providing false or misleading information on the Exemptions Register | £1,000 |
| Failing to comply with a compliance notice | £2,000 |
| Maximum combined per property, per breach | £5,000 |
Councils can also publish details of the breach. Seen against these figures, the £3,500 cap is often the cheaper route even before you count the benefit of a more efficient home to your tenants.
What about EPC C by 2030?
This is where most online coverage gets ahead of the law. GOV.UK states that the government aims for privately rented homes to reach EPC Band C or equivalent by 2030, following a consultation in 2026, with further details “to be provided in due course” (page last updated 5 May 2026).
That means, as of our last check:
- Band C is not yet a legal requirement. Band E is.
- The dates, cost cap and exemptions for any Band C rule have not been confirmed in regulations.
- Anything you read that gives a precise Band C deadline or cap as settled law should be treated with caution until the government publishes the final rules.
We track this on our landlord regulation timeline and will update this page as soon as the rules are confirmed.
How to plan if you’re somewhere between E and C
You don’t have to wait for final rules to make sensible decisions. A few practical principles:
- Get to E first if you aren’t there. That’s the legal requirement today and carries fines if you ignore it.
- Read your EPC’s recommendations. Every certificate lists suggested improvements and the rating they could achieve. That’s free information about what might be needed.
- Time works in your favour. Upgrades such as insulation or heating controls are often cheaper and less disruptive when done between tenancies or alongside other work, rather than rushed to meet a deadline.
- Don’t overspend on speculation. Until a Band C cap is confirmed, you can’t know how much you’ll be required to spend. Prioritise measures that also cut your tenant’s bills and reduce maintenance.
- Keep records. Invoices for energy efficiency work since October 2017 can count towards the current cap, so keep them.
What does an EPC cost?
There’s no fixed government price for an EPC. A 2026 guide from Home Safety UK puts the typical UK range at around £45–£85, rising with property size (roughly £70–£120 for a 2–3 bed house) and in London. Because it lasts 10 years, it’s one of the smallest compliance costs on a per-year basis. See our full guide to landlord certificate costs for gas and electrical certificates too.
EPCs and the Renters’ Rights Act
The government’s roadmap for the Renters’ Rights Act includes a Private Rented Sector database, rolling out region by region from 15 December 2026, where landlords must register every let property (at £65 per property per year) and upload safety documents including the EPC, according to a September 2026 briefing from Osborne Clarke. A valid, in-date EPC is therefore likely to become even more visible to councils and tenants.
Checklist
- Find your current EPC on the government register and check its rating and expiry date.
- If it’s F or G: plan improvements up to £3,500, or register the correct exemption.
- Give a copy of the EPC to every new tenant.
- Keep invoices for any energy efficiency work.
- Diary a review for when the government publishes the Band C rules.
How to find your EPC and get a new one
Finding an existing certificate. The government’s find an energy certificate service lets you search for EPCs in England, Wales and Northern Ireland by postcode, street and town, or certificate number. Check three things: the rating, the expiry date, and the recommendations section.
Getting a new one. If there’s no certificate or it has expired, you need a new EPC from an accredited energy assessor. There’s no fixed price, so it’s worth getting two or three quotes; timing it for when the property is empty between tenancies makes access easier.
Reading the recommendations section
Every EPC lists suggested improvements, the typical cost range the assessor has used, and the rating the property could reach if you made them. It isn’t a quote, and prices in older certificates may be out of date, but it’s a free starting point for planning. Use it to answer three questions:
- Which improvements would lift the property to at least Band E, if it’s below?
- Which improvements would get it closest to Band C, if the government confirms that standard?
- Which of those could be done at the lowest disruption — for example between tenancies?
Special situations
Your tenant won’t allow the work. If a required third party, including the tenant, refuses consent for an improvement, GOV.UK allows a consent exemption to be registered, lasting five years. Keep written evidence of the request and refusal.
You’ve just bought a tenanted property. The “recently became a landlord” exemption can give you six months to deal with a substandard property in certain circumstances.
Your property is listed or in a conservation area. Some improvements may need permissions or may be impractical. Where an improvement would damage the building or reduce its value by more than 5%, the wall insulation or devaluation exemptions may apply — but they must be registered and evidenced.
You own a leasehold flat. Improvements to the building fabric may need the freeholder’s consent. If consent is refused, that may support a consent exemption.
What this means for your costs
For most landlords, the EPC itself is a minor cost — about £45–£85 every ten years. The real cost is any improvement work. Under the current rules, your self-funded spend is capped at £3,500 including VAT. If Band C becomes law, the cost cap, dates and exemptions will be set out in new regulations; until then, any figure you see for “the cost of reaching EPC C” is an estimate, not a requirement. Factor energy efficiency work into your maintenance planning and overall costs.
