EPC Rating Lookup
Enter UK Postcode e.g. SW1A 1AA, M1 1AA, B33 8TH We'll show you every property registered at that postcode, with its current EPC band.
Free Boiler Upgrade UK is an independent eligibility-checking and application-assistance service helping households nationwide look up official EPC ratings and check ECO4 or LA Flex routes for a free boiler upgrade.
How It Works
- 1
Enter your postcode
Type any UK postcode into the box above to see every property with a registered EPC in that area.
- 2
View EPC ratings
Each result shows the property's current energy efficiency band, from A to G, taken from the official register.
- 3
Check your grant eligibility
If your home is rated D, E, F or G, find out in under a minute whether you may qualify for a free boiler or insulation upgrade.
Bottom line —Enter a postcode, read the official A–G band, then — if you're D–G — run a 60-second eligibility check for ECO4 or LA Flex.
What Is an EPC and How Are the Bands Worked Out?
An Energy Performance Certificate (EPC) rates how energy efficient a property is, on a scale from A (most efficient) to G (least efficient). It's a legal requirement whenever a home in England or Wales is built, sold, or let, and it's valid for 10 years from the date it was issued.
| EPC Band | Score | What it means |
|---|---|---|
| A | 92–100 | Highly efficient rare outside new-build homes |
| B | 81–91 | Very efficient |
| C | 69–80 | Good efficiency the government's target minimum for most homes |
| D | 55–68 | Average this is the most common band in the UK |
| E | 39–54 | Below average, higher running costs |
| F | 21–38 | Poor efficiency, high heating costs likely |
| G | 1–20 | Least efficient, typically the oldest or least-improved homes |
The certificate also lists specific recommendations such as loft or cavity wall insulation, upgraded glazing, or a new heating system along with an estimate of what they'd cost to run.
Bottom line —Band A is rare outside new builds; band D is the UK's most common — and D–G homes are the ones most often in scope for ECO4-funded upgrades.
Why Your EPC Rating Matters for Free Boiler Grants
Your EPC band is one of the two main things that decide whether you can get a free boiler or heating upgrade through the ECO4 scheme (the government's Energy Company Obligation, running to 31 December 2026, after which it's due to be replaced by the Warm Homes Plan).
The property test isn't identical for every household type:
- Homeowners and owner-occupiers: your property generally needs to be rated D, E, F or G.
- Private tenants (with landlord permission): the property usually needs to be rated E, F or G.
Meeting the EPC criteria is only half the picture you (or someone in your household) will also usually need to be receiving a qualifying means-tested benefit, such as Pension Credit, Universal Credit, or Income-Related Employment and Support Allowance, unless your local council's LA Flex scheme covers you on income or health grounds instead. If you're not sure where you stand, our eligibility checker checks both at once.
Properties rated D–G could be eligible for a free boiler or heating upgrade worth £3000–£7000, depending on the work needed and which supplier or route funds it.
Bottom line —An EPC band of D–G (or E–G for most private tenants) is necessary but not sufficient — you still need a qualifying benefit or LA Flex cover, subject to survey and supplier or council approval.
Searching by Address Instead of Postcode
If a postcode search returns several properties and you're not sure which is yours, you can usually narrow it down by adding your house number or flat number to the search. For flats and shared buildings especially, checking the full address against the result is worth doing before relying on the rating EPCs are lodged per-dwelling, and a block of flats can have several very different ratings.
Bottom line —Match the full address — especially in blocks of flats — before you rely on a band for an ECO4 application.
What If My Property Doesn't Appear?
A property won't show a result if it's never had an EPC assessment. This is common for:
- Homes that haven't been sold, let, or newly built since EPCs became mandatory in 2007–2008
- Very new properties whose certificate hasn't been lodged yet
- Certain exempt buildings, such as some listed buildings or places of worship
If your home isn't listed and you want to check ECO4 eligibility, that's not a dead end a qualifying assessor can carry out a fresh EPC as part of the application process in many cases. Check your eligibility and we'll talk you through it.
Bottom line —No certificate on the register doesn't automatically block ECO4 — a fresh assessment can often be arranged during the application.
EPC Ratings in Scotland and Northern Ireland
This checker searches the official register for England and Wales (maintained by the Ministry of Housing, Communities & Local Government). Scotland and Northern Ireland run their own separate EPC registers, so if your property is north of the border or in Northern Ireland, you'll need to search the relevant national register instead the A–G banding system and 10-year validity work the same way across all three.
Bottom line —England & Wales only on this tool — Scotland and Northern Ireland use separate registers, with the same A–G scale and 10-year validity.
Landlords: EPC Rules Are Tightening
If you let a property in England or Wales, current Minimum Energy Efficiency Standards (MEES) rules mean it must reach at least band E before you can grant or renew a tenancy, and the government has proposed raising this to band C for new tenancies later this decade. Checking your EPC now before rules tighten further gives you time to plan any upgrade, and a D-G rated rental may itself qualify for ECO4-funded improvements at no cost to you. See our free boiler grant page for how that works for rental properties.
Bottom line —MEES already requires band E minimum to let; proposed band C rules make an early EPC check — and ECO4 where eligible — practical planning, not optional.
What FreeBoilerUpgrade.uk Actually Does
We're an independent eligibility-checking and application-assistance service not the government, not an energy supplier, and not the installer. We check whether your EPC band and circumstances meet ECO4 or LA Flex criteria, help with the paperwork, and connect eligible households with Gas Safe registered installers, at no cost to the household. We can't guarantee approval or a specific outcome that's always confirmed by your energy supplier, council, or an accredited assessor after a proper assessment.
Bottom line —We check eligibility and paperwork, then connect you with Gas Safe installers — approval is always subject to survey and the supplier, council or accredited assessor.

- LA Flex
- LA Flex (Local Authority Flexible Eligibility) is the route under ECO4 that lets councils nominate households who don't receive qualifying benefits but still meet fuel-poverty or health-vulnerability criteria.
- MEES
- Minimum Energy Efficiency Standards (MEES) are the legal rules that currently require most privately rented homes in England and Wales to reach at least EPC band E before a tenancy can be granted or renewed.
- MHCLG
- The Ministry of Housing, Communities & Local Government maintains the official EPC Open Data Communities register for England and Wales that this checker searches.
- Warm Homes Plan
- The Warm Homes Plan is the government's successor programme expected to replace ECO4-funded upgrades after 31 December 2026, with grant funding directed at low-income and fuel-poor households.
What's the EPC Difference for Homeowners vs Private Tenants?
| Factor | Homeowners / owner-occupiers | Private tenants |
|---|---|---|
| Typical EPC band needed | D, E, F or G | Usually E, F or G |
| Landlord permission | Not required (you own the home) | Required before work starts |
| Benefits / LA Flex still needed? | Yes — EPC alone is not enough | Yes — EPC alone is not enough |
| Who confirms approval? | Energy supplier, council or accredited assessor | Energy supplier, council or accredited assessor |
| Rental MEES floor today | N/A (owner-occupied) | At least band E to grant or renew a tenancy |
Bottom line —Same scheme, different property bands: owners generally need D–G; private tenants usually need E–G plus landlord agreement.

Read guideFrequently Asked Questions
Answers to the most common questions about checking an EPC rating by postcode and what it means for ECO4.
What is an EPC rating?
An Energy Performance Certificate (EPC) rating measures how energy efficient a property is, on a scale from A (most efficient) to G (least efficient). It's a legal requirement when selling or letting a property in England and Wales, and it's valid for 10 years.
Is this EPC checker free to use?
Yes. This checker searches the official government EPC register at no cost, with no signup or account required. You only ever pay if you need a brand-new assessment carried out by an accredited energy assessor.
How accurate and up to date is the EPC data?
The results come directly from the official EPC Open Data Communities register, maintained by the UK government (MHCLG) for England and Wales. It's updated regularly and includes every valid EPC on record.
Can I get a free boiler if my EPC is band D, E, F or G?
Possibly. Properties in these bands may qualify for a free boiler or heating upgrade through the ECO4 scheme, but you'll also usually need to be receiving a qualifying benefit, or meet your council's LA Flex criteria. Checking your EPC band is the first step, not the whole answer.
What's the difference in EPC requirements for homeowners and tenants?
Homeowners generally need a property rated D, E, F or G to qualify for ECO4. Private tenants usually need a rating of E, F or G, and will need their landlord's agreement to have work carried out.
Why can't I find my property in the results?
A property only has an EPC if it's been built, sold or let since EPCs became mandatory (2007–2008), or if the owner has commissioned one voluntarily. If yours isn't listed, that doesn't rule out ECO4 eligibility a new EPC assessment can usually be arranged as part of the application.
How long does an EPC last?
An EPC is valid for 10 years from its issue date. If your property's last certificate is older than that, or you've made significant efficiency improvements since, it's worth getting a fresh one.
Does this checker cover Scotland and Northern Ireland?
No this tool searches the England and Wales register only. Scotland and Northern Ireland maintain their own separate EPC registers, though the A–G rating system works the same way.
What should I do if my property has a poor EPC rating?
A D-G rating often means you may be eligible for free energy efficiency improvements including boiler replacement, insulation, or heating upgrades through ECO4 or your local authority's LA Flex scheme. Check your eligibility to see what applies to your home.
