Check an EPC — then find out what it actually means

Every energy certificate in England & Wales is public. Enter an address and we'll decode its EPC rating into the things that matter: running costs at today's prices, the rental rules, and what the certificate's own numbers are worth off the asking price.

Free · no account · England & Wales certificates, straight from the official register

How it works

1

Find the address

We match it to the official England & Wales register — the same public record every certificate is filed on.

2

Say who you are

Buying, letting, selling or just curious — the breakdown is shaped around what you need from the certificate.

3

Read the decode

Costs repriced to today, element-by-element condition, the rules timeline — and the negotiation case the numbers support.

What the EPC bands mean

Every certificate scores a home from 1 to 100 and maps the score to a band, A to G. The letters carry more weight than they look — they set legal minimums for landlords, shape running costs, and increasingly move prices.

A
Score 92–100

The top of the scale — rare outside new-builds with solar.

B
Score 81–91

Where most new-builds land; little left to improve.

C
Score 69–80

The benchmark modern energy policy points at — and the rental minimum's confirmed direction.

D
Score 55–68

The most common band in England & Wales; usually a few cheap fixes from a C.

E
Score 39–54

The current legal floor for rented homes — and where quotes for insulation start paying for themselves.

F
Score 21–38

Expensive to run; typically hard to let legally without exemptions.

G
Score 1–20

The bottom band — running costs several times a C's.

What this checker actually looks up

The certificate is a public document. These four facts are why looking it up is worth a minute — and why the letter on a listing is rarely the whole story.

2008

Every home marketed for sale or let in England & Wales has needed an EPC since then.

If a listing has no certificate, that is a signal — not a gap in this checker. We look up the official register, not a private database.

10 yrs

How long a certificate stays valid. An older assessment can miss every upgrade made since.

This checker flags certificates that are stale or past expiry, because the running-cost estimate is only as current as the assessment.

14 pts

The width of band D on the 1–100 scale — two homes with the same letter can sit a long way apart.

Band D runs from score 55 to 68. The letter on the listing is the headline; the score is what the rules and the bills actually follow.

A–G

The official England & Wales scale, from the public register every certificate is filed on.

We decode the live certificate — running costs at today's prices, element condition, upgrade quotes, rental rules — not a modelled guess. Scotland and Northern Ireland keep their own registers; we point you there.

EPC questions, answered

What is an EPC rating?

An Energy Performance Certificate rates how energy-efficient a home is, from A (best) to G, on a 1–100 score assessed by an accredited domestic energy assessor. It also lists the certificate's own improvement recommendations with indicative costs — the part most people never read, and the part this tool decodes.

How do I check the EPC rating of a property?

Enter the address in the checker above. We look it up on the official England & Wales register and decode the live certificate — rating, running costs, element conditions and recommendations — free, with no account.

How long does an EPC certificate last?

Ten years. A valid certificate is required when a property is marketed for sale or rent, so an expired one usually means a fresh assessment is due — and the checker flags certificates nearing or past expiry.

What EPC rating does a rental property need?

Privately rented homes in England & Wales must meet a minimum band today, and the minimum is confirmed to rise later this decade. Run an address through the checker and the report states exactly where that certificate stands against both — kept current from one policy table, so the answer doesn't go stale in page copy.

Is a poor EPC rating a reason to negotiate?

Often, yes — and the certificate itself supplies the evidence: its own quotes for missing insulation, and running costs above an efficient equivalent. The buyer view of this tool turns those into a stated £ range, with the derivation shown.

Does this tool cover Scotland or Northern Ireland?

No — it reads the England & Wales register. Scotland and Northern Ireland keep separate registers; the tool points you to the right one when an address resolves there.

What an EPC actually tells you about a home you're thinking of buying — running costs, the rules coming, and what it's worth off the price.

  • How Long Does an EPC Last? Ten Years, and Why Age MattersAn EPC is valid for ten years from the date it was lodged on the register. A new one is required when the home is next marketed for sale or rent — not simply because the old one expired while the owner lived there. For a buyer, the certificate's age matters as much as its band.
  • What a Seller's EPC Reveals Before You OfferA seller's EPC is a public document they paid for but did not curate for you. It grades the walls, roof, windows and heating, puts indicative costs against the improvements it recommends, gives a floor area you can price per square metre, and dates the assessment.
  • Estimating a Home's Real Energy Bills Before You BuyAn EPC estimates a home's annual heating, hot water and lighting costs — but at the energy prices of the year it was produced, so an older one can be badly out. Read the kWh per m² per year figure, re-price it at today's rates, and treat the result as a comparison rather than a bill.
  • EPC Ratings A–G: What Each Band Actually MeansEPC ratings run A to G, and every band is a range of scores: A 92–100, B 81–91, C 69–80, D 55–68, E 39–54, F 21–38, G 1–20. The letter is the headline. The score underneath tells you how far the home really sits from the band above — and what closing that gap is likely to cost.
  • How to Improve an EPC Rating (and What It Costs)The cheap measures come first: cylinder insulation, loft insulation, draught-proofing, heating controls, then cavity walls. The expensive end — solid walls, glazing, heat pumps — buys far less score per pound. The certificate for that property lists which apply, with costs beside them.
  • EPC Rating D: What It Means When You're BuyingAn EPC rating of D means a score between 55 and 68 — the most common band in England and Wales, and the baseline most value comparisons start from. It is not a defect, and it is not a discount by right. What it gives a buyer is a costed, published case worth arguing.
