Landlords reviewing older energy-efficiency advice should separate the rules applying now from the government's plans for 2030. This guide concerns domestic private rented homes in England and Wales; it should not be applied automatically to commercial premises or properties elsewhere in the UK.
The current minimum
Government landlord guidance, updated in May 2026, says properties covered by the minimum energy efficiency regulations cannot be let or continue to be let below EPC band E unless a valid exemption applies. Coverage depends on the tenancy type and whether the property is legally required to have an Energy Performance Certificate.
For an in-scope home rated F or G, an owner should follow the official improvement or exemption process. The guidance describes a current improvement cost cap of £3,500 including VAT, with detailed rules about funding and qualifying expenditure. That is not permission simply to leave an inefficient home unaddressed: the relevant exemption must be registered where its conditions are met.
What the 2030 policy says
The government's January 2026 consultation response sets out a higher standard with an intended compliance date of 1 October 2030 for both new and existing tenancies. It describes a fabric-performance requirement plus a heating-system or smart-readiness measure under reformed EPCs, alongside a £10,000 maximum investment policy and exemptions.
The response also provides for homes achieving an existing Energy Efficiency Rating of C or above before 1 October 2029 to be recognised until that certificate expires or is replaced. Its implementation section describes further legislation and guidance needed to deliver the changes. These future arrangements should not be confused with a requirement to achieve C today.
A practical review for owners
Start a property-by-property file containing the certificate, recommendations, past improvement invoices and any exemption evidence. Ask an appropriately qualified assessor or retrofit professional which measures suit the building before commissioning work. A cheap individual measure is not necessarily a sensible whole-building solution.
Keep today's compliance action separate from the longer-term investment plan. Check the live government guidance before relying on an exemption, counting expenditure or agreeing a programme of works. Avoid relying on archived articles describing abandoned deadlines.
