EPC Register — Check Any UK Address by Postcode
Check the EPC register for any UK address, live. Enter a postcode below and HouseCheckup looks it up against the official MHCLG Energy Performance of Buildings register (England & Wales) — the same register behind gov.uk/find-energy-certificate — lists every domestic certificate with its A–G band and address, and shows the full detail for the newest match, ungated: current and potential band, total floor area (m² and sq ft), CO₂ emissions, and the top recommended improvements with their typical annual £ saving. Whether you want to check an EPC, find an EPC by postcode, look up a rating or read what a certificate means, this page covers it — and puts that EPC in context inside a wider £24.99 Complete report alongside 70+ other data sources Rightmove and Zoopla never show.
Instant tool. The full property report is £9.99 Lite / £24.99 Complete — one report, one price, no subscription.
What is the EPC register?
The EPC register is the official national database of every Energy Performance Certificate ever lodged for a property. In England and Wales it is the MHCLG Energy Performance of Buildings Register, searchable free at gov.uk/find-energy-certificate; Scotland and Northern Ireland run their own separate registers. Because a certificate is lodged whenever a property is built, sold or let, the register holds a live record for almost any address that has changed hands in the last decade — which is why you can check, find or look up an EPC for a home before you ever book a viewing.
How to check the EPC register
To check the EPC register, search by postcode on the official register, then pick the exact address to read its certificate. You will see the current band (A–G), the score out of 100, the issue date, the accredited assessor and the recommended improvements. The HouseCheckup checker at the top of this page runs that same lookup for you against the MHCLG register — enter a postcode and it lists the registered certificates with their band and address, and shows the newest match in full, ungated.
Find an EPC by postcode
Searching by postcode is the fastest way to find an EPC: the register returns every certificate for that postcode, so you can scan a whole street and pick the house number or flat you want. If a property has been sold or let in the last 10 years it will almost always have a valid EPC on file. If nothing appears, the certificate may have expired (EPCs last 10 years), the property may never have needed one, or it may be exempt — certain listed buildings and places of worship, for example.
EPC lookup, finder and checker — same register, different words
"EPC lookup", "EPC finder", "EPC checker" and "EPC search" all describe the same thing: querying the official register for a property's certificate. There is no separate paid finder you need — the authoritative source is free. HouseCheckup's checker is a convenience layer over that register, and then adds the context the register can't: how the EPC sits alongside flood risk, ground stability, crime and 70+ other checks for the same address.
What is an EPC, and why does it matter?
An Energy Performance Certificate (EPC) is a legally required document that rates how energy-efficient a property is, from A (most efficient) to G (least efficient), alongside a numerical score from 1 to 100. It works like the energy label on a fridge or washing machine: the higher the band, the lower the running costs. An EPC is required by law whenever a property is built, sold or rented anywhere in the UK, and it must be available to prospective buyers or tenants at the earliest opportunity.
For a buyer or renter, the EPC is the single best free indicator of what a home will cost to heat and light. For a seller or landlord, it is a legal prerequisite to marketing the property. And because every certificate is published on a public register, you can check the EPC of almost any UK address that has changed hands in the last decade — for free, before you ever book a viewing.
How do I check or find a property's EPC?
There is one authoritative, free source, and it is run by the government, not by any portal or paid service:
- England & Wales: gov.uk/find-energy-certificate — search by postcode, then pick the exact address.
- Scotland: the Scottish EPC Register, which is run separately under Scottish building standards.
- Northern Ireland: runs its own separate EPC register under Northern Ireland building regulations.
The lookup takes seconds and needs no account. Enter the postcode, choose the house number or flat, and you will see the current band, the score out of 100, the date the certificate was issued, the accredited assessor, and a full list of recommended improvements with indicative costs and savings. This is the same register estate agents, conveyancers and surveyors use.
Finding an EPC by postcode vs by address
Searching by postcode is the quickest route: the register returns every certificate registered for that postcode so you can scan a whole street. Searching by address narrows straight to one property. If a certificate does not appear, the most common reasons are that the EPC has expired (they last 10 years), the property has never been sold or let since EPCs became mandatory, or the building is exempt — certain listed buildings, temporary buildings and some places of worship do not require one.
How do I read an EPC rating?
An EPC has two headline numbers and two ratings that are easy to confuse:
- Current rating — the property's energy efficiency as it is today, shown as a band (A–G) and a score (1–100).
- Potential rating — the band and score the property could reach if every recommended improvement were carried out.
Beneath those, the certificate lists specific recommended improvements — loft insulation, cavity-wall insulation, a more efficient boiler, low-energy lighting, solar panels — each with a typical installation cost and an estimated annual saving. That section is where the real value sits for a buyer: it tells you, in pounds, what it would take to move a tired home up a band or two.
What do the EPC bands A to G mean?
There are seven bands. The table below shows the score range for each, what it broadly means for running costs, and roughly how common each band is across UK housing stock.
| Band | Score | What it means | Share of UK homes |
|---|---|---|---|
| A | 92–100 | Highly efficient — lowest running costs | ~1% |
| B | 81–91 | Very efficient | ~8% |
| C | 69–80 | Efficient — the rental minimum being proposed for 2030 | ~18% |
| D | 55–68 | Average — the most common UK band | ~32% |
| E | 39–54 | Below average — current legal minimum to let | ~25% |
| F | 21–38 | Poor — cannot be newly let | ~10% |
| G | 1–20 | Very poor — highest bills, cannot be newly let | ~6% |
Band shares are approximate, based on published EPC statistics for England and Wales, and vary by region and property age.
How long is an EPC valid, and when do I need a new one?
An EPC is valid for 10 years from its issue date. Within that window the same certificate can be reused across multiple sales or tenancies. After 10 years it expires and a fresh assessment is required before the property is sold or let again. You can also choose to renew earlier: if you have insulated, replaced the boiler or installed a heat pump, a new EPC will capture those upgrades and may push the property into a higher band — useful when you come to sell or remortgage.
How much does a new EPC cost, and what about improvements?
Looking up an existing EPC is free. You only pay when a new assessment is needed. A new EPC typically costs £60–£120, carried out by an accredited Domestic Energy Assessor who inspects the property (usually 45–60 minutes) and lodges the certificate on the national register.
The cost of improving a rating depends entirely on the works. As a rough guide based on the kind of figures shown on EPC recommendations: loft insulation often pays back within a few years; cavity-wall insulation is similarly cost-effective; a new condensing boiler is a larger outlay but a common step from band D to C; and measures like external wall insulation or a heat pump are the most expensive route to the top bands. The EPC itself estimates each measure's cost and annual saving, which is why it doubles as a free home-efficiency plan.
EPC rules for sellers and landlords
If you are selling, you must have a valid EPC before you market the property, and it must be provided to buyers at the earliest opportunity — estate agents cannot legally advertise a home without one. If you are letting, the property must currently reach at least band E under the Minimum Energy Efficiency Standards (MEES) in England and Wales; you cannot grant or renew a tenancy on an F- or G-rated home without a registered exemption. The government has proposed raising the minimum to band C for new tenancies by 2030, which would require many landlords with D-rated stock to invest in upgrades. Non-compliance penalties run to several thousand pounds per property.
Where HouseCheckup fits in
The checker at the top of this page does the lookup for you — enter a postcode and it returns the certificates on the official register, each with its band and address. For the authoritative full certificate (every recommended measure, the assessor, the raw figures) the government register at gov.uk/find-energy-certificate remains the source of record, and we link you straight to it. The limitation of the register, either way, is that it shows the EPC in isolation. It will not tell you whether the property also sits in a flood zone, on shrink-swell clay, near former coal workings, in a high-crime area or next to a pending planning application — the things that actually decide whether a home is a good buy.
That is the job HouseCheckup is built for. The Complete report (£24.99) combines the EPC with 70+ official data sources into a single 18-page report and a composite IQ Score, covering flood risk, area quality, price history and valuation, crime, schools and more. Neither Rightmove nor Zoopla brings these together — the portals show the listing; HouseCheckup shows whether the property survives due diligence.
