An Energy Performance Certificate lasts 10 years from the date it was entered on the national register, in England, Wales and Northern Ireland. It expires on the "valid until" date printed on the certificate, unless a newer certificate for the same property is lodged first, in which case the older one stops counting straight away.
That second part is the bit most landlords miss. This guide covers what triggers a new certificate, what you can safely ignore, and when renewing early pays off, with current law and the proposed 2030 changes kept firmly apart.
How long does an EPC last?
Ten years. Regulation 9 of the Energy Performance of Buildings (England and Wales) Regulations 2012 says a certificate is valid only if it "was entered on the register no more than 10 years before the date on which it is made available". The clock starts on the day the assessor lodges it, which is usually the same day as, or a day or two after, the visit.
Three details follow from that wording:
- The date that matters is the register date, not the survey date. They are normally close together, but the register is what a council enforcement officer will check.
- There is no partial validity. A certificate is valid on day 3,652 and invalid on day 3,653. Nothing about the rating fades or downgrades over time.
- A newer certificate replaces an older one. Regulation 9 also requires that "no other energy performance certificate for the building has since been entered on the register". More on why that catches landlords out below.
The government considered cutting validity to five years. In its partial response to the EPC reform consultation, published 21 January 2026, it decided against that: "We intend to maintain the current ten-year validity period for reformed EPCs, whilst existing EPCs will retain their ten-year validity, in recognition of consultation responses highlighting the cost of commissioning EPCs more regularly." So 10 years applies to every certificate you hold now and to the reformed certificates due from the second half of 2027.
Scotland runs a separate register under its own regulations; see our Scottish landlord EPC guide for that side of the border.
How do I check if my EPC is still valid?
Use the free GOV.UK service at gov.uk/find-energy-certificate. It covers England, Wales and Northern Ireland. You can search by postcode, by street name and town, or by certificate number. Each certificate page shows the rating, the numeric score, the "Valid until" date and the assessor's details. The PDF downloads at no cost.
Three things to check while you are there:
- The valid until date. Note it in your compliance calendar. If it falls inside the next 18 months, read the early-renewal section below first.
- That the address matches your unit, not the building. A converted house or a block can hold several certificates at similar addresses. Your tenancy needs the one for the specific flat you let.
- That the certificate you gave your tenant is the newest on the register. If anyone has lodged a later assessment, the copy in your tenancy pack is no longer the valid one.
If you manage several properties, our postcode EPC lookup pulls the rating and expiry for each address in one go. For a walkthrough of the register, including what to do when a property does not appear at all, see how to find an EPC certificate.
When does a landlord legally need a valid EPC?
The 2012 Regulations attach the duty to letting events. Regulation 6 requires the landlord (the "relevant person") to make a valid EPC available free of charge to any prospective tenant at the earliest opportunity. It also requires that the person who becomes the tenant has been given one. Regulation 7 adds the marketing duty: a certificate must exist before the property is advertised.
In practice you need a valid certificate:
- Before marketing the property to any new tenant, through an agent or yourself.
- Before granting a new tenancy, including a new fixed term signed with the tenant already in place.
- On the register, at the point a council checks the property for MEES compliance. Since 1 April 2020 a property rated F or G cannot be let without a registered exemption. The council needs a valid certificate to establish the band.
The penalty for missing the regulation 6 or 7 duties on a dwelling is a fixed £200 under regulation 38. That is separate from MEES, where letting a sub-standard property carries a maximum civil penalty of £5,000 per property under the 2015 Regulations. Our EPC fines guide sets out both regimes side by side.
The January 2026 response also confirmed a wider scope once reformed regulations arrive: a valid EPC for a whole HMO when a single room is let, for short-term lets whoever pays the energy bills, and for heritage properties that were previously exempt. See the HMO EPC guide and the listed building guide for those property types.
Does an EPC have to be renewed mid-tenancy?
Not under current law. If your certificate expires while the same tenant remains in place under the same agreement, no letting event has occurred, so regulations 6 and 7 do not bite. You are not in breach.
The government did propose that rented properties should hold a valid EPC throughout the tenancy. The January 2026 response deferred that decision: "we are working to refine the position on requiring a new EPC when an existing one expires for all private rented buildings, to ensure the policy has its intended effect." A final response is promised for 2026. Until then the position is unchanged.
One caveat: a new tenancy agreement with the same tenant is a letting event, so a renewed fixed term needs a valid certificate first. Our full guide to EPC expiry mid-tenancy covers the edge cases, including what changes if the continuous-validity proposal is adopted.
When should a landlord renew an EPC early?
A certificate does not have to be expired for a new one to make sense. The question is whether a fresh assessment will improve your position, because under regulation 9 it replaces whatever is on the register, better or worse.
| Situation | Renew early? | Why |
|---|---|---|
| Just completed insulation, boiler or heating works | Yes, once the works are finished | The old certificate does not credit the new measures. A new one records the higher score for the next 10 years |
| About to market or re-let with under 12 months left | Usually yes | Avoids a mid-tenancy expiry and a possible renewal under changed rules |
| Current rating is D or E and you are planning works before the proposed 2030 band C date | Only after the works | An early certificate before works records the same low band for another decade |
| Current rating is C under RdSAP and expires between late 2027 and October 2029 | Consider it | Renewing under current methodology keeps a C on the register until well past 2030 |
| Certificate expired mid-tenancy, no new agreement planned | Not required | No letting event, no breach under current law |
| Certificate valid, no works, no letting event | No | A new assessment could score lower and would replace the existing one |
A certificate lodged today runs to 2036, straddling every announced or proposed change to the regime.
After improvement works
This is the clearest case. A certificate issued before a new boiler, loft insulation or cavity fill still shows the pre-works score. It will keep showing it for the rest of its 10 years if you do nothing. Commission a new assessment once everything is installed. Have the invoices and product specifications ready for the visit; an assessor who cannot verify an insulation depth or boiler model may have to assume a default value, which costs points. What an assessment costs varies by area.
Before a new tenancy
If the certificate will expire during a tenancy you are about to grant, renewing beforehand removes the question altogether. It also gives the new tenant a certificate that reflects the property as it is today.
Before the proposed 2030 standard
The proposed band C minimum from 1 October 2030 is not law; government still needs an Act of Parliament and a statutory instrument, targeted for 2027. If you are already at C, a certificate that records it and runs past 2030 is worth having. If you are at D or E, an early certificate achieves nothing until the works are done; see the E to C upgrade guide for sequencing.
Before the methodology switch
Reformed EPCs using the Home Energy Model are now due in the second half of 2027, after the government moved the launch from October 2026. From 1 October 2029 all new certificates must use the new model. A property scoring 69 to 72 under today's RdSAP could land in band D when reassessed under HEM, particularly with gas heating. Our guide to locking in EPC C before the 2029 switch works through whether that applies to your property.
Not sure whether your property is worth reassessing now or after works? Our Action Plan takes your current certificate and gives you a costed route to C, measure by measure, with the recommended order and when to book the new assessment. Start your Action Plan
What invalidates an EPC before the 10 years are up?
Only one thing in law: a newer certificate lodged for the same building. Regulation 9(2)(b) makes the most recent certificate the only valid one. Nothing else cancels a certificate early.
That has consequences the top-ranking guides skip:
- Works do not invalidate a certificate. Replacing a boiler, adding an extension or removing loft insulation leaves the existing certificate legally valid until its expiry date. The rating may be wrong, but it is still the certificate of record.
- A worse new certificate replaces a better old one. If a lender, buyer or agent commissions a fresh assessment and it scores lower, that lower score is now your rating. A landlord with a 2019 C who orders a 2026 reassessment "to be safe" and gets a D has handed the council a D.
- You cannot pick which certificate to use. Once a newer one is on the register, the older PDF in your filing cabinet is worthless for compliance.
So never commission a new assessment without a reason to expect the score to hold or improve. Before booking, run the property through our EPC predictor to see whether the current rating is likely to survive. The EPC analyser shows what your existing certificate assumed about the fabric and heating.
Does an old EPC still count after the Home Energy Model launches?
Yes. Every existing certificate keeps its original expiry date. The January 2026 response confirmed that existing EPCs "will retain their ten-year validity". The March 2026 update that moved reformed EPCs to the second half of 2027 changed nothing about certificates already on the register.
For the proposed 2030 standard, government has said that a band C obtained under current methodology before October 2029 would count as compliant for the rest of its 10-year life. That statement sits inside a proposal, so it could change when the legislation is drafted. Our guide to what happens to your EPC after the Home Energy Model tracks it.
What is law today and what is only proposed?
| Rule | In force now (England and Wales) | Proposed, not yet law |
|---|---|---|
| EPC validity | 10 years from register date | Stays at 10 years (confirmed, January 2026) |
| Valid EPC needed throughout a tenancy | No, only at marketing and new tenancy | Decision deferred to a further response in 2026 |
| Minimum band to let | E (since 1 April 2020) | C from 1 October 2030 |
| Landlord cost cap | £3,500 including VAT | £10,000 |
| Maximum MEES penalty | £5,000 per property | £30,000 |
| Missing EPC on a dwelling | £200 fixed penalty | Unchanged so far |
| Registered exemption length | 5 years | 10 years, on three grounds only |
Nothing in the right-hand column can be enforced until an Act passes and a statutory instrument amends the 2015 Regulations. For the full picture see the 2030 EPC C deadline guide.
Frequently Asked Questions
How long does an EPC last in the UK? Ten years from the date it was entered on the register, in England, Wales and Northern Ireland. The government confirmed in January 2026 that the 10-year period stays for both existing and reformed certificates. Scotland has its own register and its own regulations.
Is my EPC still valid if it was issued more than 10 years ago? No. A certificate older than 10 years is expired and cannot be used to market or let the property. Check the exact date at gov.uk/find-energy-certificate, where the "Valid until" date is shown on the certificate page.
Do I need a new EPC if my tenant stays and the old one expires? Not under current law. A valid certificate is required when you market the property or grant a new tenancy, so an ongoing tenancy on the same agreement does not trigger a renewal. A proposal to require continuous validity was deferred in the January 2026 response and remains undecided.
Does an EPC expire if I do building work? No. Works do not cancel a certificate; only a newer certificate on the register does. The existing rating may no longer reflect the property, so after energy improvements it is worth commissioning a new assessment to record the higher score.
Can I use the EPC the previous owner or landlord had? Yes, as long as it is still within its 10 years and no later certificate has been lodged. The certificate attaches to the building, whoever commissioned it. Download it free from the GOV.UK register.
What is the fine for letting without a valid EPC? A fixed penalty of £200 per dwelling under regulation 38 of the 2012 Regulations, for failing to provide or hold a certificate at marketing or letting. Letting a property rated F or G without a registered exemption is a separate MEES offence with a maximum penalty of £5,000 per property.
Will my current EPC still be valid when the new Home Energy Model EPCs arrive? Yes. Existing certificates keep their original expiry date after reformed EPCs launch in the second half of 2027. You only need a new-style certificate when your current one expires or a letting event requires one after the switch.
Should I renew my EPC now to lock in a C before 2030? Only if your property already scores C and the certificate would otherwise expire between late 2027 and October 2029. A renewal now under current methodology keeps that C on the register until 2036. If you are at D or E, wait until the improvement works are done, because a new certificate replaces the old one whatever it scores.
