Does an EPC expire automatically after ten years or does someone need to renew it?

It simply lapses at the ten-year mark from lodgement; there is no automatic renewal process, and no new certificate is generated unless one is separately commissioned when needed.

If I renovate my home, does my existing EPC become invalid?

No, it remains legally valid for its full ten-year term regardless of renovation, though it will no longer accurately describe the property, which is a good practical reason to get a new one even without a legal duty to do so.

Can I sell a property using an EPC that still has time left on it?

Yes, provided it is still within its ten-year validity period, an existing EPC can be used when marketing and selling a property; there is no requirement to obtain a fresh one purely because a sale is happening.

Do I need a new EPC every time I get a new tenant?

Not if a valid, in-date EPC already exists for the property and it still meets the applicable MEES band; a new certificate is only required if the previous one has expired or none exists.

How do I find out exactly when my EPC expires?

Search the EPC Register by your property's address or the certificate's report reference number; the lodgement date is shown, and adding ten years gives the expiry date.

Is there a grace period after an EPC expires before I need a new one?

No formal grace period exists; the requirement to have a valid certificate applies at the relevant trigger event, such as marketing for sale or letting, so a new one should be arranged before that point rather than after an expired one is discovered.

How long does an EPC last, and when do you need a new one?

There is no legal duty to renew an EPC mid-life. The ten-year validity period, and the specific events that actually force a new certificate, explained plainly.

How long does an EPC last, and when do you need a new one?

The short answer

An Energy Performance Certificate is valid for ten years from the date it is lodged on the EPC Register, regardless of any changes made to the property during that period. There is no general legal duty to renew it earlier than that, unless a specific trigger event requires a valid certificate that the existing one does not cover — most commonly marketing the property for sale or let, or letting where the previous certificate has since expired. Outside those situations, an in-date certificate remains legally valid for its full ten years even if the property has since been renovated, its heating system replaced, or its rating would clearly now be different.

The headline rule: ten years from lodgement

Every domestic and commercial EPC is valid for exactly ten years, counted from the date it was lodged on the national EPC Register, not from the date the assessor visited the property, though in practice these dates are usually only a day or two apart. This validity period is fixed by regulation and applies uniformly regardless of the property type, its rating, or what happens to the building during that decade.

Validity is measured from lodgement date, which is shown on the certificate itself and on the Register entry.
The rule applies equally to A-rated and G-rated properties — there is no shorter validity period for poorly performing buildings.
Commercial EPCs follow the identical ten-year rule as domestic ones.
A certificate remains technically valid throughout the ten years even if it no longer accurately reflects the property.

Why there is no general mid-term renewal duty

This surprises a lot of owners: replacing a boiler, adding insulation, or fitting new double glazing does not, on its own, create any legal requirement to get a new EPC before the existing one expires. The certificate remains valid on paper for its full term regardless of what has physically changed. The obligation to have a valid EPC is tied to specific trigger events — principally marketing a property for sale or let — rather than to keeping the certificate continuously up to date with every change made to the building.

No legal duty to update after a boiler replacement, insulation upgrade or new windows, however significant.
No duty to update after an extension, unless the property is then marketed and no valid certificate covers the new floor area.
The existing certificate continues to satisfy legal requirements until it expires or a trigger event requiring a different certificate arises.
This differs from some other compliance documents that require review after any material change — EPCs specifically do not.

The buildings behind this advice

The events that do actually require a new certificate

While ongoing renewal is not required, specific events do create a legal need for a valid, current EPC, and if the existing one has expired or does not exist at all, a new assessment is needed before proceeding. These trigger points are the same ones that first created the requirement for an EPC in the first place.

Trigger event	New EPC needed if...	Notes
Selling a property	No valid, in-date EPC currently exists	Must be commissioned before marketing begins
Letting to a new tenant	No valid, in-date EPC currently exists	Also subject to MEES minimum band for commercial and most residential lets
New construction	Always, for the completed dwelling	As-built EPC generated from final specification
Significant refurbishment	Sometimes, where Part L compliance is separately triggered	Depends on scope and nature of works

Landlords: why checking early matters more than the ten-year clock

For landlords, the ten-year rule can create a false sense of security, because MEES compliance is judged against the current in-date certificate's band at the point a new lease is granted, not against when it happens to expire. A certificate that is still technically valid but shows band F, obtained years ago before improvements were made, could unnecessarily block a new letting if nobody thinks to get it reassessed beforehand.

Check the current certificate's band well before agreeing terms on a new lease, not after.
If genuine improvements have been made since the last assessment, a new EPC can capture them and potentially avoid MEES issues altogether.
An expired certificate at the point of a new letting must be replaced before the letting proceeds.
Portfolio landlords should track expiry dates across all properties rather than reacting only when a specific letting is imminent.

When it is worth getting a new EPC before it expires

Outside of a legal trigger, there are still good practical reasons to commission a new EPC before the old one lapses. If a property has been meaningfully improved — better insulation, a new heating system, double glazing installed — a new certificate captures that improvement and can be a genuinely useful marketing asset, a stronger MEES compliance position, or simply a more accurate record for a remortgage.

After significant energy efficiency improvements, to reflect and evidence the better rating.
Ahead of marketing a property for sale, even if the existing certificate has a few years left, to ensure it reflects the property's current condition.
Before agreeing a new commercial or residential lease where the existing band is close to or below the MEES threshold.
Where the existing certificate is several years old and the property has changed hands or been altered since, for an accurate baseline.

Checking your current certificate's status

Before commissioning anything new, it is worth confirming what currently exists and when it expires, since the answer is a two-minute search rather than a guess. The national EPC Register holds every valid and historic certificate for a property, searchable free of charge by address or report reference number.

Search the EPC Register by postcode and house number or name to find the current certificate.
Check the lodgement date shown on the record, then add ten years to establish the expiry date.
Expired certificates remain visible on the Register, clearly marked as no longer current.
If in doubt about whether a trigger event applies to your situation, treat marketing or letting as requiring a valid certificate to be safe.
