The Government has provided long-awaited clarity on the future of Minimum Energy Efficiency Standards (MEES) for England and Wales’ non-domestic private rented sector. Crucially, the latest announcement revises both the timeline and the scope of the proposed regulations.

MEES sets the minimum Energy Performance Certificate (EPC) rating that privately rented commercial buildings must achieve before they can legally be let. At present, most non-domestic rented properties must meet a minimum EPC rating of E, unless a valid exemption applies.

What’s changing for MEES?

However, the Government’s interim response confirms several important changes to MEES:

  • A new target date: Large privately rented commercial buildings (over 1,000m²) will be expected to achieve EPC B by 2031, where improvements are cost-effective.
  • A more targeted approach: Buildings below 1,000m² will continue to be subject to the current minimum standard of EPC E.
  • The EPC C milestone has been dropped: The previously proposed requirement for an interim EPC C rating by 2027 will no longer be introduced.
  • Existing exemptions remain: The current seven-year payback test and other exemption mechanisms will continue to apply.
  • Legislation is still to come: The proposals require secondary legislation before they become law.

More time, but no reason to delay action

Although the revised MEES timetable provides greater certainty for building owners and operators, it should not be viewed as a reason to delay. Improving an EPC rating is rarely achieved through a single project, particularly across ageing commercial estates. Planning ahead allows asset owners to spread investment, minimise disruption and avoid a last-minute rush to comply.

There is also a growing concern around stranded building stock. Buildings that cannot economically achieve future EPC requirements risk becoming harder to let, less attractive to occupiers and investors, and ultimately less valuable. As ESG commitments and energy performance become increasingly important in commercial property decisions, efficient buildings are likely to enjoy a significant competitive advantage.

For many buildings, lighting represents one of the quickest and most cost-effective ways to improve energy performance. Upgrading to LED lighting and adding wireless lighting controls can significantly reduce energy consumption, improve occupant comfort and support better EPC outcomes, often without the disruption or cost associated with major refurbishment.

Wireless controls – the route to 40% savings

The latest MEES announcement may have extended the timeline, but it hasn’t changed the destination. Our advice to landlords, asset managers and facilities teams is that early investment in proven energy-saving technologies, including wireless lighting controls, can form an important part of a wider strategy to improve building performance.

Our wireless control solutions typically deliver 40% energy savings (on top of savings from any existing LED lighting) – all of which makes a major contribution to reducing operational costs and prepare for future compliance.
