Residential property is moving through a significant reform of Energy Performance Certificates (EPCs) and a confirmed new minimum standard for the private rented sector. Unlike the non-domestic sector, where the government's position is still described as interim on several points, the residential timeline and figures below are set out in a full government response and are further along in the legislative process.
A new-style EPC from October 2026
The government intends to launch a reformed domestic EPC from October 2026. The current single A to G Energy Efficiency Rating is being replaced with four headline metrics: energy cost, fabric performance, heating system, and smart readiness. Two secondary metrics, covering energy demand and a carbon-based measure, will also appear on the certificate.
The existing rating will not disappear immediately. It is being retained alongside the new metrics for a transition period, so it can continue to be used to check compliance with existing regulatory measures until it is no longer needed. Certificates will continue to be valid for ten years, matching the current position.
Two further changes affect how and when an EPC is needed. First, an EPC will be required at the point a property is marketed for sale or rent, rather than allowing a window of up to 28 days afterwards. Second, the scope of properties requiring a certificate is being widened, including whole Houses in Multiple Occupation where a single room is let, short-term rental properties regardless of who pays the energy bills, and the removal of the current exemption for certain heritage buildings.
The new minimum standard: EPC C by 1 October 2030
For the private rented sector, the government has confirmed that landlords in England and Wales will need to bring homes up to EPC Band C by 1 October 2030. Compliance is assessed against a dual-metric standard: the new fabric performance metric, plus either the heating system metric or the smart readiness metric, whichever the landlord chooses.
The cost of compliance is capped. Landlords will not be required to spend more than £10,000 per property, or 10% of the property's value if that figure is lower. The government's own estimate of average spend to reach compliance is £5,400, below the headline cap.
A landlord who already holds an EPC C, on the current rating, before 1 October 2029 is treated as compliant until that certificate expires or is replaced. This gives an incentive to act early rather than wait for the 2030 deadline itself.
A number of exemptions apply, most lasting five years, including where the cost of works exceeds the cap, where all relevant improvements have already been made, where third-party consent cannot be obtained, and where independent evidence shows the works would reduce the property's value by more than 5%. The cost cap and property value exemptions last ten years. Solid wall insulation has its own specific exemption route where expert evidence shows a negative structural impact. A new landlord also has a temporary exemption in the months immediately after taking on a property.
Enforcement will sit with local authorities, who will be able to issue penalties of up to £30,000 per property per breach, checked against the Private Rented Sector Database and the Energy Performance of Buildings Register. Short-term lets are currently excluded from these MEES rules, though this is under review. All other tenancy types are in scope.
The government intends to bring forward primary legislation for the new enforcement powers, with secondary legislation to follow once the EPC reform itself is confirmed. Regulations are intended to come into force in 2027, ahead of the October 2030 compliance deadline itself.
Part of a wider £15 billion programme
This reform sits within the government's £15 billion Warm Homes Plan, running from 2025/26 to 2029/30. The plan funds grants, low and zero interest loans, and supply chain support for insulation, solar panels, batteries, and heat pumps. The Boiler Upgrade Scheme continues to offer grants of £7,500 for heat pumps, alongside newer grants for air-to-air heat pumps with heat batteries and for biomass boilers in rural properties. A new Warm Homes Agency is being established to consolidate existing delivery bodies and simplify the process for households and installers.
Separately, the government is consulting for the first time on introducing an EPC Band C standard for the social rented sector, alongside continued funding through the Warm Homes Social Housing Fund.
What this means for residential landlords
For landlords planning ahead of 2030, the transition arrangement is worth noting in particular: reaching EPC C before 1 October 2029, on the current rating system, locks in compliance until that certificate expires, rather than requiring a fresh assessment against the new dual-metric standard. Given the cost cap and the government's own average cost estimate, most works are likely to fall within the £10,000 limit, but landlords with properties that are expensive to treat, for example solid-walled or off-gas-grid stock, should check the specific exemption routes early rather than assuming the general cap applies cleanly.
