Quick answer
By 1 October 2030, every privately rented home in England and Wales must meet a new, higher minimum energy efficiency standard - unless the landlord has registered a valid exemption or already locked in compliance under transitional grandfather rights. This replaces the current EPC E minimum that's applied since 2020. Landlords may be required to invest up to £10,000 per property, though government's own estimate puts the average spend at around £5,400.
What's changing from today's rules
Since 2020, private landlords in England and Wales have had to meet a minimum of EPC E, with a maximum required spend of £3,500 per property. That standard hasn't moved in over five years - but energy prices, fuel poverty levels, and the government's Net Zero commitments have.
Under the new rules, the minimum jumps significantly. It isn't simply "EPC C" in the way many landlords assume. It's a new dual-metric standard, and it applies via a reformed EPC system that measures homes differently to how they're measured today.
The single compliance date: 1 October 2030
Government originally consulted on a phased approach - new tenancies would have had to comply from 2028, with all tenancies following by 2030. That phased approach has been dropped. There is now one compliance date for every tenancy: 1 October 2030. There's no earlier deadline for new lets, new tenants, or newly re-let properties, everyone has the same date.
What the new standard actually is
This is the part that trips a lot of landlords up: the 2030 standard isn't a flat "get to EPC C" target on today's EPC. It's a dual-metric standard measured on reformed EPCs, which will use a new calculation method (the Home Energy Model, or HEM) in place of the current RdSAP methodology.
To comply, a property needs to meet:
Fabric performance
How well-insulated and heat-efficient the building's structure is - loft insulation, cavity wall insulation, double glazing, draught-proofing, and similar.
Smart readiness or heating system
Smart readiness covers solar panels, batteries and smart meters. The heating system route covers upgrading to a lower-carbon heating system such as a heat pump.
Landlords are not required to install a heat pump to comply. If a property can't meet the smart readiness route, it isn't then forced onto the heating system route, and vice versa, as long as some measures were installed against at least one of the two secondary metrics, no landlord will be required to rip out a working gas boiler purely to hit this standard.
How much you'll actually have to spend
A few things affect how the cap works in practice:
- It's a combined cap across both the fabric and secondary standard - not £10,000 for each.
- Spend from 1 October 2025 on measures recommended by your EPC counts toward it, even ahead of the new standard formally applying.
- Third-party grant funding generally counts toward the cap too - with one exception: funding from the Boiler Upgrade Scheme (BUS) does not count toward the cap, giving landlords using BUS's £7,500 heat pump grant extra headroom.
- If a property is worth less than £100,000, a separate Property Value Adjustment exemption caps required spend at 10% of the property's value instead of the full £10,000.
If you reach the cap and the property is still below standard, you can register a cost cap exemption, valid for 10 years, and continue letting the property.
Grandfather rights: the early-action shortcut
If your property already scores a C or above on the Energy Efficiency Rating (EER) — the metric on today's EPCs - before 1 October 2029, it's treated as compliant with the new 2030 standard for as long as that EPC remains valid (EPCs are valid for 10 years).
Miss that 1 October 2029 cutoff, and you'll instead need to bring your property up to the new dual-metric standard on a reformed EPC.
What if you genuinely can't reach the standard?
The regulations keep a system of EPC exemptions for situations where installing a measure isn't possible or appropriate - and government has expanded this list:
New landlord
6 months, for anyone taking on a tenanted property.
Cost cap
10 years, once you've spent up to the cap.
All relevant improvements made
5 years, when there's genuinely nothing left the EPC recommends.
High-cost
5 years, if even the cheapest recommended measure exceeds the cap.
Third-party consent
5 years or length of tenancy, if a tenant, freeholder, or planning authority won't consent.
Property Value Adjustment
10 years, for properties under £100,000.
Negative Impacts
10 years, where a measure would harm or devalue the property by 5%+.
Solid Wall Insulation
5 years — landlords can simply opt out of installing SWI by declaration.
Registering a valid exemption lets you continue letting the property until the exemption expires — at which point you'll need to try again to bring it up to standard. See the full exemptions guide →

FAQs
Sources: the £10,000 cost cap, MEES deadline, exemptions regime, and fines figures in this article are drawn from HM Government's "Improving the energy performance of privately rented homes: government response" (GOV.UK, updated 21 January 2026). The delay of reformed HEM-based EPCs to the second half of 2027 — originally targeted for October 2026 — is confirmed directly against HM Government's own HEM:EPC methodology documentation (GOV.UK, updated 17 March 2026), and does not affect the 1 October 2030 compliance deadline. This is a live policy area — the underlying regulations are still subject to Parliamentary approval, and exact HEM metric thresholds had not been finalised as of the sources checked, so some figures may be refined before the rules take legal effect.
