Key takeaways
- An EPC is valid for 10 years from when it is lodged, however many times you let or sell in that time.
- A landlord needs a new EPC only when marketing or letting after the old one has expired. Expiry mid-tenancy does not by itself trigger a new one.
- A new EPC replaces the old one, even if it scores worse. Don't commission one without a reason.
- An EPC rated C issued before 1 October 2029 is planned to count towards the 2030 standard until it expires or is replaced.
- New-style EPCs are now due in the second half of 2027. The government says existing EPCs keep their 10-year validity.
In this guide
An Energy Performance Certificate lasts 10 years from the date it is lodged on the national register. In England a landlord needs a new one only when marketing or letting the property after that date. A certificate that expires during a tenancy does not have to be replaced until the next marketing. Those are the rules in force on 3 November 2026.
The ten-year rule is the easy part, and our EPC service page covers it briefly. This guide covers the questions that cause real mistakes: what "valid" means for a landlord, when an expired certificate matters, why a fresh one can work against you, and how the 2027 and 2030 changes affect timing. For the wider picture on the coming standard, start with our guide to EPC C by 2030. We are EliteShires Property Services, based in Kenton, and we assess EPCs across Harrow, Kenton, Stanmore and Edgware.
Is an EPC valid for 10 years, whatever happens?
Yes, with one exception. An EPC "is valid for 10 years" and "can be reused as many times as required within that period", whether the home is let or sold in that time (GOV.UK guide to EPCs for dwellings). The exception is a newer certificate. "Only the most recent EPC for each distinct building or building unit is valid." Lodging a new EPC ends the old one's life early.
That rule is why the date on your certificate is not the only thing to check. A landlord who commissions a new EPC "to be safe" may replace a C with a D if the method or the evidence differs. The new certificate is the one that counts, even if it scores worse.
You can check the date, rating and expiry of any certificate on the GOV.UK Find an energy certificate register. It shows a warning when a certificate has expired.
When does a landlord need a new EPC?
You need a valid EPC whenever you market a property to let, and you must give one to the new tenant. If the current certificate is in date, you reuse it. If it has expired, you commission a new one before the listing goes live. The table covers the common situations.
Do you need a new EPC? Common situations (checked October 2026)
| Situation | New EPC needed? | Why |
|---|---|---|
| Re-letting with an EPC under 10 years old | No | A valid EPC can be reused for any number of lets |
| Re-letting after the EPC has expired | Yes, before marketing | You must commission one before marketing and make it available at the earliest opportunity |
| EPC expires while a tenant is in place | Not at that point | Nothing triggers one until you next market or let |
| Major works, such as insulation or a new heating system | Not required, but often wise | A new EPC records the improvement |
| Property sold with tenants in place | Seller needs a valid EPC to market it | The 10-year rule is the same for a sale |
| Letting one room in a shared house | No EPC for the room itself today | An EPC is not required for an individual room. The whole building needs one if let as a whole |
Two terms matter. You must commission an EPC before marketing, and make it available "at the earliest opportunity" to anyone who asks about the property or views it. A tenant must receive a copy free of charge. Trading Standards can issue a £200 penalty where a landlord fails to do so (GOV.UK guide; Energy Performance of Buildings Regulations 2012, regulation 38). If you are selling, our list of the certificates needed to sell a house shows where the EPC fits.
Should you renew an EPC early?
Only if you have a reason. Our EPC service page answers the short version. There is no early-renewal window for EPCs, unlike the two-month window for gas safety checks. A new certificate simply starts a new ten years and retires the old one.
Good reasons to commission a new EPC before the old one expires:
- You have finished improvement works, and the old rating no longer reflects the home. The new certificate is your evidence of the work.
- The current rating is F or G, and you have works planned or need evidence for an exemption.
- The old certificate contains errors, such as missing loft insulation that is actually there. Ask the original assessor first. If that fails, the certificate names the accreditation scheme to complain to.
Weak reasons: "it's nearly ten years old" or "the agent asked for a new one" when the certificate is still in date and accurate. A valid EPC already on the register does the job.
How does the 2030 decision change the timing?
It gives some certificates a longer working life: under the January 2026 decision (not yet law), a C issued before 1 October 2029 counts towards the 2030 standard until it expires or is replaced (GOV.UK government response, 21 January 2026).
So the issue date becomes something to plan around.
- A C issued in 2026 would run to 2036, well past the 1 October 2030 deadline.
- A C issued in 2021 expires in 2031. After that, compliance will be measured on the new-style metrics.
- A D close to C has until 30 September 2029 to be improved and re-assessed on today's scale.
Will the new-style EPCs change how long certificates last?
No. In its January 2026 response on EPC reform, the government said it intends to "maintain the current ten-year validity period for reformed EPCs". It also said "existing EPCs will retain their ten-year validity" (GOV.UK partial government response, reforms to the energy performance of buildings regime). Both points still need Parliament's approval.
New-style EPCs are now due in the second half of 2027 (GOV.UK, updated 9 March 2026); our EPC C by 2030 guide explains the new metrics.
The reform response also plans changes for shared houses and heritage homes. It intends to clarify the EPC rules by "requiring a valid EPC to be provided for a whole HMO when a single room is let", and "removing exemptions for heritage properties". Neither is in force. If you let rooms, our guide to HMO safety rules covers the duties that apply now. For listed homes, see EPCs for listed and conservation-area homes.
Who checks EPCs locally?
Two teams at your council. Trading Standards enforces the duty to provide an EPC. The private housing team enforces the minimum energy standard. Which council depends on the address: Harrow covers Harrow and Stanmore. Kenton is split between Harrow and Brent, partly along Kenton Road, so it depends on your street. Edgware is mostly in Harrow or Barnet. The private rented sector database will also ask for each property's EPC, under regulations laid before Parliament in draft in September 2026; our guide to the landlord database covers the dates and uploads.
When you book with us, we check the national register first. If a valid certificate already exists and nothing has changed, we tell you, and you don't pay for one you don't need. If you do need one, the assessment is a fixed price confirmed before we attend, and the certificate is lodged within 24 hours. Our guide to what an EPC costs and why explains what sets that price. That makes it easy to time a new EPC just before a listing goes live. For the bigger planning question, see the 2030 guide linked above, or book an energy assessment.
