The current rule is straightforward: every rental property in England and Wales must hold a valid EPC rating of E or above. You cannot legally let a band F or G property without a registered exemption. Beyond that, the government has proposed raising the minimum to C by October 2030, but that change is not yet law.
This guide covers what is in force now, what is only proposed, and what you need to do before the end of 2026 to access grant funding that closes on 31 December.
What EPC Rules Apply to Landlords Right Now?
Under the Minimum Energy Efficiency Standards (MEES) Regulations (SI 2015/962, England and Wales only), three rules are in force:
| Rule | Detail | Legal basis |
|---|---|---|
| Minimum rating | Band E or above | Regulation 22 |
| Cost cap | £3,500 inc VAT maximum landlord spend | Regulation 24 |
| Maximum civil penalty | £5,000 total per property | Regulation 40 |
MEES applies to England and Wales only. Scotland and Northern Ireland operate separate frameworks with different timelines.
The cost cap works as a ceiling on compulsory spending: if a property cannot reach band E within £3,500 of eligible works, the landlord can register a cost cap exemption and let the property legally. The same cap principle applies under the proposed 2030 changes, but the amount rises to £10,000.
The £5,000 penalty covers the total breach per property, not a per-month charge. Local housing authorities enforce it; enforcement rates vary by council.
What EPC Changes Are Coming in 2030?
The government has proposed raising the minimum to band C from 1 October 2030. This is not yet law.
On 21 January 2026, the government published its response to the MEES consultation confirming this intention. For it to take effect, two things must happen:
- A new primary Act of Parliament must pass (targeted for 2027, not yet introduced)
- A Statutory Instrument must be laid under that Act (not yet laid)
Until both steps happen, band E remains the legal minimum. The Renters Rights Act 2025 did not change the EPC penalty or the minimum rating.
If the proposed 2030 rules pass as described, the key figures change:
| Rule | Current law | Proposed from Oct 2030 |
|---|---|---|
| Minimum rating | Band E | Band C |
| Cost cap | £3,500 inc VAT | £10,000 inc VAT |
| Maximum penalty | £5,000 per property | £30,000 per property |
| Qualifying spend period | N/A | From 1 October 2025 |
The qualifying spend point matters: eligible EPC improvements commissioned from 1 October 2025 count toward the proposed £10,000 cap. Landlords who start upgrading now can bank that spend against the future threshold.

Which Properties Are Exempt?
A landlord can register an exemption on the national PRS Exemptions Register and let legally, even if the property is below the minimum. Valid exemptions include:
- Cost cap exemption: all appropriate improvements up to the cap cannot bring the property to the required band
- Third-party consent: a freeholder, planning authority, or other third party refuses consent for works
- Listed building or heritage: works would unacceptably alter the character of a listed or heritage-designated structure
- Newly let property: a six-month grace period when a landlord first lets a property that becomes newly relevant to the regulations
- Devaluation: a qualified surveyor confirms the works would reduce market value by 5% or more
Exemptions last five years (the newly-let exemption lasts six months). You must re-register or carry out improvements when they expire.
According to EPCGuide's analysis of 29.2 million EPC records, 49.6% of homes in England and Wales currently sit below band C. Many landlords with older stock will need either genuine upgrades or valid exemptions to comply with the proposed 2030 rules.

What Grants Can Landlords Use?
Two schemes are currently open. A third replaces them from 2027.
ECO4 (closes 31 December 2026)
The Energy Company Obligation scheme (ECO4) funds insulation and heating upgrades for low-income households. The grant covers up to £14,000 per property.
Eligibility is tenant-gated, not landlord-gated. Your tenant must receive certain means-tested benefits for the property to qualify. Landlords cannot apply directly; the route is through an approved ECO4 installer who assesses tenant eligibility.
ECO4 closes on 31 December 2026. The successor scheme, the Warm Homes Plan, is expected from 2027 but full details have not been confirmed. If your tenant qualifies, act before year end.
Boiler Upgrade Scheme (BUS)
The Boiler Upgrade Scheme provides a £7,500 grant toward the cost of installing an air source or ground source heat pump. Landlords are eligible. It is not means-tested.
The installer claims the voucher directly; you pay the remaining balance. BUS covers the heat pump unit and installation only. It does not fund insulation or other fabric improvements.
Warm Homes Plan (from 2027)
The government has confirmed the Warm Homes Plan will replace both ECO4 and GBIS (which closed 31 March 2026) from 2027. Details including grant amounts and eligibility criteria are not yet published.
What Happens If You Break EPC Rules?
Letting a property below the required EPC band without a registered exemption can result in a civil penalty of up to £5,000 per property. The £5,000 is the total cap under current law.
Non-compliance can also create problems beyond the penalty:
- Some buy-to-let mortgage lenders require band D or C at remortgage; a non-compliant property can block refinancing
- A MEES breach creates a title defect that must be disclosed on sale
- If the proposed £30,000 penalty is enacted, the exposure rises sixfold
Enforcement sits with local housing authorities. Some councils actively pursue breaches; others do not. The risk of getting caught is not uniform, but the legal exposure is.
EPC Compliance by Property Scenario
| Property situation | Current position | Action |
|---|---|---|
| Band A, B, C, D or E | Legal to let today | Renew EPC before it expires (valid 10 years) |
| Band F or G | Cannot legally let | Improve to band E, or register a valid exemption |
| Band D or E | Legal today, below proposed 2030 minimum | Begin planning upgrades; bank eligible spend from Oct 2025 |
| Listed building | Possible exemption | Confirm with assessor whether works are permissible |
| Leasehold flat | Third-party consent may be needed | Seek written consent from freeholder; register exemption if refused |
| Tenant qualifies for ECO4 | ECO4 grant available | Act before 31 December 2026 when scheme closes |

The Home Energy Model: EPC Methodology Is Also Changing
The EPC rating methodology itself is set to change. The current SAP (Standard Assessment Procedure) system produces the familiar A-to-G band. The government plans to replace it with the Home Energy Model (HEM), which generates four separate metrics: fabric performance, heating system efficiency, smart readiness, and energy cost.
Reformed domestic EPCs are expected in the second half of 2027. What this means for landlords: the band a property achieves under SAP may differ from what HEM produces. Properties that currently scrape band E may find their position changes in either direction under the new methodology. Getting improvements in now, under the current scoring system, avoids uncertainty about how the new model will assess your property.
Frequently Asked Questions
What is the minimum EPC rating to rent out a property in England? Band E is the current legal minimum under the MEES Regulations (SI 2015/962). Bands F and G cannot be legally let without a registered exemption on the PRS Exemptions Register. The government has proposed raising this to band C from October 2030, but this requires primary legislation that has not yet been passed.
What is the fine for renting a property with a low EPC? The maximum civil penalty under current law is £5,000 per property per breach. If you let a band F or G property without a registered exemption, the local housing authority can impose this penalty. The proposed 2030 rules would raise the maximum to £30,000 per property, but this is not yet law.
Do EPC rules apply in Scotland? No. The MEES Regulations (SI 2015/962) apply to England and Wales only. Scotland operates its own Private Rented Sector (Energy Efficiency) Regulations with different requirements and timelines.
When will the EPC minimum become band C? The government has proposed 1 October 2030 as the date for all tenancies (new and existing) to reach band C. This is proposed only. The change requires primary legislation and a Statutory Instrument, neither of which has been introduced as of September 2026. The legal minimum remains band E.
What is the cost cap for EPC improvements? Under current law, landlords must spend up to £3,500 inc VAT on eligible improvements before they can register a cost cap exemption. The proposed 2030 rules would raise this to £10,000 inc VAT. Eligible spend from 1 October 2025 would count toward the proposed cap, so improvements made now may reduce what you need to spend later.
Does my EPC need to be renewed for each new tenancy? No. An EPC is valid for 10 years from the date of issue and does not need renewing between tenancies within that period. You must hold a valid (not expired) EPC and provide it to a prospective tenant before they sign a tenancy agreement.
