EPC B by 2031: what the new MEES timetable means for commercial buildings

By V1 Energy Solutions · 17 July 2026

In June 2026 the government finally answered the question commercial landlords had been asking for five years: what will the Minimum Energy Efficiency Standards actually require, and when? Here is the new timetable in plain English, and what a sensible facilities or estates manager does about it now.

What was announced

For non-domestic private rented buildings in England and Wales, the government confirmed a minimum EPC rating of B from 2031 for larger buildings, those over 1,000 square metres. The interim EPC C milestone previously proposed for 2027 has been dropped and will not be taken forward. Smaller properties, under 1,000 square metres, stay subject to the existing minimum of EPC E for now, with no new deadline announced.

The existing flexibility mechanisms are retained, including the seven-year payback test, so only cost-effective improvements are mandated. The detail arrives through secondary legislation and updated guidance, which the government says will follow at the earliest opportunity. Until that passes, treat the dates as confirmed policy intent rather than final law.

Who should be paying attention

The obvious answer is landlords of larger commercial buildings, who now have roughly five years to get from wherever they are to a B. The less obvious answer matters more for our readers: many care homes and hotels sit in lease structures, sale-and-leasebacks and opco/propco arrangements, where the building is technically rented even though everyone thinks of it as "ours". If your buildings are held that way, MEES is your problem too, on either side of the lease.

And even where MEES doesn't bite directly, EPC ratings increasingly do: lenders price against them, ESG reporting collects them, and lease events surface them at the worst possible moment.

An honest caveat about EPCs

Here is something many efficiency suppliers won't tell you: an EPC is a modelled asset rating, not a meter reading. Measures improve your EPC when they change the modelled performance of the building and its services. A measure that verifiably cuts your metered consumption always helps your bills and your carbon reporting; whether it moves your EPC score depends on how your assessor can treat it. Before spending serious money in the name of EPC B, ask your assessor which measures will actually move your rating. It is a twenty-minute conversation that regularly saves five-figure mistakes.

What to do between now and 2031

First, know your numbers: pull the current EPC for every building, note the expiry dates, and flag anything below C over 1,000 square metres as priority. Second, build a metering baseline now, because every credible efficiency decision you make between here and 2031 will be judged against it. Third, sequence the work sensibly: controls and low-disruption efficiency measures first, invasive capital works planned around lease and refurbishment cycles. Fourth, verify everything against meter data, supplier claims included.

The buildings that hit 2031 comfortably will not be the ones that did everything at once in 2030. They will be the ones that started banking verified savings early, with the evidence to show for it.

Where V1 fits

Our system is a low-disruption efficiency measure: wrapped around closed-loop heating and cooling pipework, no downtime, and every project verified against the customer's own meters, with results like the 27% verified saving at Ablecare Homes.
