EPC Exemption Guide for Welsh Landlords

In short: Wales uses two official registers. To find or check an Energy Performance Certificate, use the gov.uk Find an energy certificate service, which covers England, Wales and Northern Ireland. To register an exemption for a rental property rated below Band E, use the PRS Exemptions Register, the single register for England and Wales. Anyone can search registered exemptions. A Welsh landlord can let a property below Band E only once a valid exemption is registered.

The EPC register in Wales: where to check a certificate or an exemption

There's no separate Welsh EPC register. Welsh properties sit on the same gov.uk services as England, and the certificate search is also available in Welsh. Pick the service that matches what you want to do.

What you want to do	Official service	What you need
Find a property's EPC and its rating	Find an energy certificate (England, Wales and Northern Ireland)	A postcode, a street name and town, or the certificate number
Register or manage an exemption for your rental	Register a private rented sector energy standards exemption	A GOV.UK One Login, the property address, a valid EPC and the evidence for your exemption
Check whether a property already has an exemption (or a penalty)	View private rented sector energy standards exemptions	A postcode, street name and town, landlord name or exemption type. No login needed

The exemptions search shows when a property was registered as exempt and the reason. The landlord's name only shows where the landlord is a company or other organisation, not an individual. The same search also lists penalties councils have issued to landlords for breaking the energy efficiency rules.

Do I need an EPC to rent out my house in Wales?

Yes. Almost every rental property in Wales needs a valid Energy Performance Certificate. Order it before you advertise. You must then make every reasonable effort to have it in hand within 7 days of first marketing the property. To let the property, the rating must be Band E or above, unless you've registered a valid exemption.

You must give the EPC to prospective contract-holders (tenants) and include the current rating in any property advertisement. Search the government's EPC Register to check what's already on file for your property, and get a fresh assessment from an accredited domestic energy assessor if you don't have a current one.

What EPC rating do I need to rent in Wales?

The current legal minimum is Band E. It has applied to new lets of privately rented property in Wales since 1 April 2018, and to all lets since 1 April 2020, under the Minimum Energy Efficiency Standards (MEES, SI 2015/962). If your property is rated F or G, you can't legally let it unless a valid exemption is registered.

Rent Smart Wales's own guidance confirms this is still the current standard: most rental property should have an EPC rated E or above, and a property rated below E is likely to fail the minimum standard.

The UK Government has announced a move to Band C from 1 October 2030. That is policy, not law. As at 10 October 2026 the amending regulations have not been made, so nothing changes for landlords today.

The announced policy also proposes a cost cap of up to £10,000 per property to reach Band C. It would allow a 10-year exemption if the property is still below Band C after that spend. Neither applies until the regulations are made.

Feature	Today	From 1 October 2030 (announced, not yet law)
Minimum EPC rating	Band E	Band C (proposed)
Legal status	In force since 1 April 2020	Policy announced; amending regulations not yet made (as at 10/10/2026)
Penalty for letting below the minimum	Up to £5,000 total per property (tiered, see below)	Not yet set

Status check: no amending regulations for the Band C change appear in the legislation.gov.uk list of changes to SI 2015/962, and the gov.uk MEES landlord guidance still sets Band E as the minimum (both accessed 10/10/2026).

What exemptions exist and how long do they last?

If your property doesn't meet Band E, you don't necessarily have to bring it up to standard before you can let it. Six exemption types are available for domestic rented property. Each has its own test, evidence and duration. None takes effect until it's registered on the PRS Exemptions Register.

Exemption	What it covers	Duration	Evidence needed
All relevant improvements made	Every improvement that qualifies has been made (up to the £3,500 cost cap), or none qualify, and the property is still below Band E	5 years	Details of the improvements made (or evidence none qualify), registered on the PRS Exemptions Register
High cost	Even the cheapest recommended improvement would cost more than the £3,500 cost cap	5 years	Three quotes from qualified installers (who meet the installer standards), showing the cheapest recommended improvement costs more than £3,500 including VAT
Wall insulation	The only recommended improvement is cavity, external or internal wall insulation, and expert advice says it would harm the property's fabric or structure	5 years	A written opinion from an independent installer who meets the installer standards, or from an independent architect, chartered engineer or chartered building surveyor on a recognised conservation register
Third-party consent	A tenant, superior landlord or other third party refuses consent to the improvement, or only agrees subject to a condition you can't reasonably meet	5 years, or until that tenant's tenancy ends, if it was the tenant's refusal you relied on	Evidence of the request and the refusal
Property devaluation	A report from an independent surveyor on the RICS register of valuers shows the improvement would cut the property's market value by more than 5%	5 years	The surveyor's report
New landlord (specific circumstances)	You've just become the landlord in a narrow set of legal circumstances: for example buying a property with a tenant already in it (this covers that existing tenancy only, not a new let), a lease granted by court order, or taking over the lease as guarantor after the tenant became insolvent	6 months from the date you became the landlord	None beyond registering the exemption itself

Listed status isn't one of these exemptions. It's a separate question. Under different rules, a listed building may not need an EPC in the first place if bringing it up to standard would unacceptably alter its character or appearance (Energy Performance of Buildings (England and Wales) Regulations 2012, regulation 5(1)(a)). If your listed property does have a valid EPC below Band E, it's the MEES exemptions above that apply, not its listed status.

How do I register an EPC exemption?

Whichever exemption applies, the process is the same five steps.

1. Check your current rating on the EPC Register. You need a valid EPC to register an exemption.
2. Work out which exemption fits your circumstances from the table above. See the government's own MEES landlord guidance for full detail on what qualifies.
3. Gather the evidence it needs: three installer quotes, a surveyor's report, a written opinion, or proof of the refusal, as applicable.
4. Sign in to the PRS Exemptions Register with a GOV.UK One Login (the sign-in changed to One Login on 5 May 2026). It's the single register covering both England and Wales.
5. Enter your details (or the landlord's details, if an agent is registering on the landlord's behalf), the property address and the EPC, then upload the evidence for your exemption.

You can let the property immediately after registering a valid exemption. Every exemption applies from the date you register it, not from the date you qualified, so register before you let. Your local council, as enforcement authority, may still contact you for more information, and can challenge an exemption it doesn't accept as valid.

How do I check or manage an existing exemption?

Sign in to the same register service to manage exemptions you've already registered. To check any property without logging in, for example one you're buying with a contract-holder in place, use the public exemptions search. It shows the exemption type and the date it was registered. Most exemptions last 5 years (see the table above), so note that date and check where the property stands well before the exemption runs out.

What counts as a qualifying improvement, and what evidence the council will accept, can get technical. The gov.uk landlord guidance linked above sets out each test in full.

How much does an EPC cost?

There's no fixed government fee for an EPC assessment. The cost depends on your property and the assessor you use. It's worth getting more than one quote from an accredited domestic energy assessor. The £10,000 figure sometimes mentioned in this context is the announced (not yet law) cost cap for 2030 improvements, not the assessment fee itself.

Check the EPC Register first. If a valid certificate already exists, you don't need a new one just to check where you stand.

What happens if you don't comply

MEES is enforced by the local council for the area your property is in. Letting below the legal minimum without a registered exemption carries a financial penalty. The council can also publish details of the breach, and that publication penalty is separate. The financial penalties are:

• Up to £2,000 if the breach has run for less than 3 months
• Up to £4,000 if the breach has run for 3 months or more
• Up to £1,000 for registering false or misleading information on the PRS Exemptions Register
• Up to £2,000 for failing to comply with a compliance notice

These can stack, but the total financial penalty for one property is capped at £5,000.

Practical next steps

Check your current EPC rating on the EPC Register. If it's below Band E, you'll need either an exemption or improvements before you can let legally. If it's below Band C and you want to plan for 2030, keep your EPC's recommendation report and get quotes for the improvements now. The quotes will be useful whenever the rules are made final.

Frequently asked questions about EPC exemptions in Wales

Where is the EPC register for Wales?

Wales uses the gov.uk Find an energy certificate service, which covers England, Wales and Northern Ireland. You can search by postcode, street name and town, or certificate number.

How do I check if a rental property has an EPC exemption?

Use the gov.uk View private rented sector energy standards exemptions search. It covers England and Wales, needs no login, and shows the exemption type and the date it was registered.

Do I need an EPC to let a property in Wales?

Yes. Almost every rental property needs a valid EPC, ordered before you advertise. It must meet the current minimum rating (Band E) unless you've registered a valid exemption.

What EPC rating do I need to rent in Wales?

Band E or above. This has been the legal minimum since 1 April 2020 under the Minimum Energy Efficiency Standards. Below that, you need a registered exemption to let legally.

Is Band C required now?

No. The government has announced a move to Band C from 1 October 2030, but this is policy, not law; the amending regulations haven't been made as at 10 October 2026, so today's minimum is still Band E.

What is the EPC cost cap?

Under the announced (not yet law) 2030 policy, the proposed cap is up to £10,000 per property spent on recommended improvements, with a 10-year exemption available if a property is still below Band C after that spend.

How do I register an EPC exemption?

Check your rating, work out which of the six exemptions fits your circumstances, gather the evidence it needs, then register it on the PRS Exemptions Register: an exemption only takes effect once it's registered.

What exemptions are available and how long do they last?

Six exemption types exist for domestic rented property: all relevant improvements made, high cost, wall insulation, third-party consent and property devaluation each last 5 years; a new landlord exemption lasts 6 months from the date you became the landlord. All must be registered on the PRS Exemptions Register before you can rely on them.

Is a listed building automatically exempt from EPC rules?

No. Listed status isn't a MEES exemption. Separately, under the EPC-requirement rules, a listed building may not need an EPC at all if compliance would unacceptably alter its character, but if it does have a valid EPC below Band E, the MEES exemptions above are what apply, not its listed status.

What's the penalty for letting a non-compliant property in Wales?

Letting a property below the legal minimum EPC rating without a registered exemption is enforced by your local council: up to £2,000 for a breach under 3 months, rising to up to £4,000 at 3 months or more, plus a separate publication penalty. The total financial penalty for one property is capped at £5,000.

How much does an EPC cost?

There's no fixed government fee: costs vary by assessor and property, so it's worth getting more than one quote. The £10,000 figure sometimes quoted is the proposed 2030 improvement cost cap, not the assessment fee.
