Living in an EPC F or G property: the tenant enforcement walkthrough (MEES + RRA, 2026)

If your home has an Energy Performance Certificate rating of F or G, your landlord has almost certainly been letting it to you illegally since at least April 2020. Most renters never check the EPC, and even when they do, they read the rating as informational rather than a legal red flag. It is the latter. The Minimum Energy Efficiency Standards (MEES) Regulations make it unlawful for a private landlord to let a domestic property with an EPC of F or G unless they have a valid, registered exemption. The maximum penalty per breach is GBP 30,000.

This walkthrough is for the tenant who has noticed the EPC is sub-E and wants to know what to do with that information. The short answer: it gives you significant leverage, both with the landlord directly and through the local authority enforcement route. The Renters' Rights Act 2025 does not change the underlying MEES rule, but it interacts in ways that make the tenant position stronger overall.

Quick test: do I have the leverage?

Three checks settle it.

Check 1 - the EPC. Find the property's EPC on the EPC register at find-energy-certificate.service.gov.uk. Search by address. If the EPC rating is F or G and was issued within the last ten years, you are looking at an illegal let.

Check 2 - the exemption register. A landlord can register an exemption (the property is genuinely unimprovable, the consent route has failed, the cost cap has been hit, etc.). Exemptions are recorded on the PRS Exemptions Register. Search by address. If the property has a current registered exemption, the let is lawful and the MEES route is closed. If there is no exemption, proceed.

Check 3 - the date the tenancy started. The MEES rules applied first to new tenancies from 1 April 2018 and then to all tenancies (including ones already running) from 1 April 2020. If your tenancy started after April 2020, the rule covers your whole tenancy. If it started before April 2018 and you have been continuously in occupation since, the rule still bites from 1 April 2020.

If all three checks point to an illegal let, you have a strong position. The walkthrough below shows how to use it.

What MEES actually says

The Energy Efficiency (Private Rented Property) (England and Wales) Regulations 2015 - known as MEES - prohibit a landlord from letting a domestic privately rented property where the EPC rating is below E (i.e. F or G) unless:

• The landlord has made all "relevant energy efficiency improvements" up to the cost cap (currently GBP 3,500 including VAT), or
• The landlord has registered a valid exemption on the PRS Exemptions Register.

The local authority is the enforcer. They have powers to serve compliance notices, then financial penalties of up to GBP 30,000 per breach (the maximum was raised from GBP 5,000 in late 2025). The penalty is per property, per breach, and can be repeated.

The MEES rules do not directly create a tenant right to compensation. But they do create a clear breach of housing legislation, which feeds into other tenant rights (disrepair claims, Decent Homes claims, possession defences under the RRA).

How the rule has changed in 2026

Three changes matter.

Change 1 - penalty raised to GBP 30,000. From late 2025 the maximum penalty per breach is GBP 30,000 (up from GBP 5,000). This makes councils more willing to investigate, because the financial-penalty route is now worth the staff time.

Change 2 - PRS Database (from 1 May 2026). The new PRS Database includes EPC data. A landlord who is letting an F-or-G property without a registered exemption is now visible to the council via a database lookup. Previously the council had to do field investigation; now it is one search.

Change 3 - RRA interaction. The Renters' Rights Act 2025 does not list MEES breach as an RRO offence directly. But it strengthens tenant remedies in two adjacent areas: the Decent Homes Standard (which now applies to the private rented sector and which an F-or-G property is unlikely to meet) and disrepair claims (where poor energy performance often correlates with damp and cold). So the tenant who is in an illegal F-or-G let can usually run two parallel claims - the MEES report to the council, plus a disrepair / Decent Homes claim against the landlord.

The headline 2030 target - EPC C for all PRS by 2030 - is forward-looking and does not affect current enforcement. Do not let landlord-side commentary about the 2030 target distract from the fact that F-or-G is already unlawful today.

How landlords get this wrong

Three patterns.

Pattern 1 - "the EPC is old, ignore it". A common landlord response is that the EPC pre-dates current standards. The MEES rules apply to whatever EPC is on the register at the time of the let. If the most recent EPC is F or G, the let is illegal until a fresh EPC of E-or-above is obtained or a valid exemption is registered. There is no grandfather clause.

Pattern 2 - "I have applied for an exemption". An application is not a registration. The let only becomes lawful when the exemption is registered and approved, not when the application is submitted. Until then, the breach continues.

Pattern 3 - "the works are too expensive". The cost cap is GBP 3,500 including VAT. If the works would exceed the cap, the landlord can apply for an "all relevant improvements made" exemption after spending up to the cap and getting a quote for the rest. Without that registered exemption, the cap argument does not help.

If your landlord uses any of these arguments, the tenant-side response is to point to the EPC register and the (absent) exemption register, and to put the council on notice.

The three-step tenant route

Step 1 - document the position. Screenshot the EPC register page showing the F or G rating, dated. Screenshot the exemption register search showing no registered exemption, dated. Note the tenancy start date. Note the current rent. This is the file.

Step 2 - write to the landlord (optional but useful). A short letter putting the landlord on notice that the let is unlawful under MEES. This is optional - the tenant has no obligation to give the landlord a heads-up - but it sometimes triggers improvements at the landlord's cost (rather than the council's intervention) and is a useful escalation step. Template below.

Step 3 - report to the local authority. The council's housing or environmental health team enforces MEES. Most councils have an online "report a private rented property issue" form, or accept email reports. The report should include the address, the EPC rating, the exemption-register search result, and your role as tenant. Ask for an acknowledgement and a case reference.

The council should investigate, issue a compliance notice if appropriate, and follow through with a financial penalty if the landlord does not bring the property up to standard.

The letter to the landlord

[Your name]
[Property address]
[Today's date]

[Landlord / managing agent name]
[Landlord / managing agent address]

Re: Minimum Energy Efficiency Standards - tenancy at
[property address]

Dear [Name],

I write further to my tenancy at the above property,
which commenced on [tenancy start date].

The Energy Performance Certificate for the property,
dated [EPC date], records a rating of [F / G]. There is
no registered exemption on the PRS Exemptions Register
(search conducted on [date], reference [if any]).

Under the Energy Efficiency (Private Rented Property)
(England and Wales) Regulations 2015, it has been
unlawful to let a domestic property with an EPC rating
below E since 1 April 2020. Maximum financial penalties
per breach are now GBP 30,000.

I would be grateful if you could confirm by return:

1. What works are planned to bring the property up to
   the required standard, and the proposed timescale.
2. Whether an exemption application is intended, and
   on what ground.

If I do not receive a substantive response within
fourteen days, I will report the position to [council
name] for the council's consideration under its MEES
enforcement powers.

Yours sincerely,

[Your full name]
[Phone number]
[Email]

The letter is structured to do three things:

1. State the breach precisely with documentary references.
2. Offer the landlord a chance to remedy it.
3. Set a fourteen-day clock before escalating to the council.

It is not adversarial. It is informational. About half the time the landlord starts works. The other half lands at the council.

The council report

When the fourteen days run out (or sooner, if the tenancy is at risk), send the council a short report. Most councils have an online form; if not, email the housing or private-sector team.

Include:

• The property address.
• A statement that the EPC rating is F or G with the EPC reference number.
• A statement that no exemption is registered, with the date of the exemption-register search.
• The tenancy start date and your continued occupation.
• A copy of any prior correspondence with the landlord (the letter above).
• Your contact details.
• A request for an acknowledgement and case reference.

The council has a duty to investigate and a power to issue a compliance notice. If they do not act within a reasonable time (usually 8-12 weeks), follow up in writing. Some councils are slow on MEES enforcement; persistence works.

What if the council sits on it

Three options.

Option 1 - escalate within the council. Ask for the case to be reviewed by a senior officer or the head of housing. Quote the GBP 30,000 maximum penalty - this is the council's revenue, and they should be paying attention.

Option 2 - go to your councillor. A short email to the local councillor often unsticks slow housing cases. The councillor can chase the relevant officer with more authority than the tenant can.

Option 3 - external escalation. The Local Government Ombudsman investigates "maladministration causing injustice" in council services. A council that sits on a clear MEES breach for many months may be open to a Local Government Ombudsman complaint.

In parallel, the tenant always retains the disrepair / Decent Homes Standard route directly against the landlord. An F-or-G property is very likely failing the Decent Homes Standard, and the RRA's expansion of Decent Homes to the PRS means that route is now available. See our Decent Homes Standard tenant enforcement walkthrough for the parallel route.

What NOT to do

Three traps.

Do not withhold rent on MEES grounds. Withholding rent is risky for any tenant and does not strengthen the MEES position. The MEES enforcement route is via the council; the tenant's parallel claim is via disrepair, which does not depend on rent withholding.

Do not move out without recording the position. A tenant who leaves quietly loses the MEES leverage. If you are planning to move, document the EPC and exemption position before you go - it remains useful for any future deposit dispute or rent recovery, and the council can still investigate a historic breach.

Do not accept the landlord's "informal" remediation without paperwork. If the landlord offers to install insulation or a new boiler "in lieu" of the formal enforcement, get the work specified in writing with a date for an updated EPC assessment. Verbal promises rarely deliver.

Where the RentSOS check fits

The free RentSOS check focuses on Form 4A rent increases. Many landlords in F-or-G properties try to push through above-market rent increases, knowing the property would not stand up to a market-rent challenge at tribunal. A procedurally invalid Form 4A is its own challenge route - run the free check, and if there are grounds, the procedural-challenge letter ends the increase at no cost. The MEES leverage runs alongside.

Frequently asked questions

My EPC is old - does the rule still apply?

Yes, provided the EPC is the current one on the register for the property. An EPC is valid for ten years. The MEES rule applies to the most recent valid EPC. If there is a valid EPC of F or G on the register, the property is unlawful to let. If the EPC has expired and there is no replacement, the landlord must obtain a fresh EPC before letting - and if the fresh one is also F or G, the same rule bites.

What if my landlord registers an exemption after I report?

The exemption only protects the landlord from the date of registration. The historic breach (before registration) is unaffected. The council can still consider penalties for the historic period. So a late exemption registration does not undo your report - it just brings future enforcement to an end.

Can I claim compensation directly from the landlord for the illegal let?

There is no direct tenant compensation under MEES. But the breach contributes to parallel claims - particularly disrepair, where damp/cold from poor energy performance is often the medical evidence. The Decent Homes Standard route, now applicable to the PRS under the RRA, is the most direct adjacent route. Speak to a housing solicitor about combining the claims.

Will reporting affect my tenancy?

It should not. Retaliation by a landlord against a tenant for reporting a housing offence is itself unlawful, and the RRA strengthened the anti-retaliation provisions on 1 May 2026. If the landlord serves a Form 6A after you report MEES, the retaliation defence is available. Make sure the report and any landlord notices are well-documented in time order.

What about properties with EPC E - are they safe?

EPC E meets the current MEES minimum. The forward-looking target is EPC C by 2030, but that is future regulation and not currently enforceable. An EPC E let is lawful today. If the EPC slips to F (e.g. on re-assessment after disrepair), the rule then bites.

Key takeaways

• Letting a domestic property with an EPC of F or G has been unlawful since 1 April 2020. Maximum financial penalties were raised to GBP 30,000 per breach in late 2025.
• The tenant route is: screenshot the EPC register, screenshot the exemption register showing no exemption, write to the landlord, then report to the local authority.
• The 2030 EPC C target is forward-looking and does not affect current enforcement. F-or-G is already a breach.
• The RRA does not list MEES as an RRO offence, but the Decent Homes Standard route (newly applicable to the PRS) often runs in parallel - an F-or-G property is unlikely to meet the standard.
• Do not withhold rent on MEES grounds. Do not move out without documenting the position. Do not accept informal remediation without written specification.
