THE PRACTICAL ANSWER
Older EPC B by 2030 headlines should be read against the later government response. The stated direction is now a proposed 2031 requirement for larger rented commercial buildings; current qualifying commercial lettings remain subject to EPC E unless exempt.
Current MEES minimum: EPC E for qualifying lettings, unless exempt. Domestic equivalent EPC C for October 2030 is announced policy requiring implementation. Commercial EPC B from 2031 for buildings over 1,000m² is a proposal requiring legislation.
Check the current policy summaryThe wording “commercial EPC B by 2030” describes an earlier policy trajectory, not a universal current legal deadline. This article keeps its original URL so existing links continue to work, but the policy position needs to be read against the latest government response.
What applies today?
Qualifying non-domestic rented property in England and Wales is subject to the current EPC E minimum unless a valid exemption applies. Establish the building’s scope, certificate coverage and tenancy position before deciding what action is required.
What does the June 2026 response propose?
The interim response proposes EPC B from 2031 for rented buildings larger than 1,000m², where cost effective. The earlier proposed EPC C milestone for 2027 is not being taken forward. The higher standard requires secondary legislation; it should not be presented as an enacted requirement applying to every commercial building.
Why the building details matter
Record the floor area, use, certificate boundaries, servicing arrangements and proposed transaction. A multi-let office, industrial unit and shop with residential accommodation above can require different assessment and evidence questions. Do not infer the scope solely from the address or the existing rating letter.
Where a lease, assignment, renewal or purchase is involved, review responsibilities with the appropriate property professional. Responsibility for compliance, responsibility for obtaining a certificate and the contractual allocation of improvement costs are separate questions.
Build a proportionate improvement brief
Start with a reliable assessment of the building. Investigate appropriate measures and modelling, access and tenant coordination, quotations, relevant cost-effectiveness tests and the evidence needed for any exemption route. Keep the completed-work record so that reassessment can consider the actual specification.
A promised EPC B outcome without a building-specific assessment is not a sound investment basis. Likewise, a generic deadline should not be used to commission unnecessary work. Set the project scope around current duties, the asset decision and the confirmed regulatory position.
