Long awaited MEES Clarity from Government on Commercial EPC ratings

The Government has finally dropped its long-awaited interim response on strengthening the Minimum Energy Efficiency Standards (MEES) for commercial leased properties.

If you’ve been sweating over what the future holds for your portfolio, we finally have some concrete direction. But in typical policy fashion, the update answers a few big questions while leaving a glaring hole for smaller commercial spaces.

Here is exactly what’s happening, what it means for your wallet, and why doing the bare minimum remains a risky strategy.

Shift in focus to larger properties

The Government is shifting its crosshairs onto larger commercial properties with a very specific target:

• The Big Rule: All rented non-domestic buildings over 1,000m² must achieve an EPC B by 2031 (provided the upgrades are cost-effective).

• Get out of jail free: Smaller buildings under 1,000m² are off the hook for now. They just have to stick to the current minimum standard of an EPC E.

• The Scrapped Milestone: The previously proposed interim deadline to hit an EPC C by 2027 has been completely binned.

• The Safety Nets: The existing exemptions and the trusty 7-year payback rule aren't going anywhere. If a green upgrade doesn't pay for itself within seven years, you won't be legally forced to do it.

  
  

The Government’s logic? They want to focus fire where it hits hardest, claiming this targeted push will save tenants in these larger buildings a combined £360 million a year in energy bills by 2031.

Our Take: A bit too narrow?

While we always welcome clarity, this 'big buildings only' approach feels like the most politically comfortable way forward. Landlords holding prime, substantial commercial assets are usually already on top of this and considerable attention will have already been given to their HVAC systems and structural composition. They are driven by corporate ESG targets, institutional investors, and high-caliber tenants demanding green credentials. They were moving toward an EPC B anyway if not already there.

By completely excluding properties under 1,000m², the policy ignores high street shops, local offices, and small commercial hubs. It begs the question: how are we supposed to hit nationwide decarbonisation goals if a massive chunk of the high street is left sitting at a mediocre Grade E?

What this means for your portfolio

Whether you manage a sprawling industrial park or a boutique deli, here is your action plan:

1. If you own properties OVER 1,000m²

The clock is officially ticking. Snapping your fingers and jumping to an EPC B doesn't happen overnight it takes strategic planning, smart asset management, and capital expenditure. Waiting until 2030 to look at your fabric and HVAC systems is a surefire way to face compliance bottlenecks and inflated contractor rates.

2. If you own properties UNDER 1,000m²

Take a breath, but don't get complacent. Just because the legal floor stays at an EPC E for now doesn’t mean it will stay there forever. Look at the domestic rental sector, they are already staring down a tight shift to EPC C by 2030. Policy moves fast, and the goalposts will shift eventually. Lenders and tenants are already leading the way in demanding better buildings, to some extent the Government is dragging its feet behind the real gate-keepers here.

The Next Steps

Keep in mind, these proposals still need to pass through secondary legislation before becoming absolute law, and we're expecting a more detailed full response from the government down the line.

But as your go-to compliance partner, our advice is always the same: know where you stand.

Don’t guess your ratings, and don't rely on an outdated certificate from any old assessor. Start reviewing your portfolio, identify the cost-effective quick wins now, and build a long-term asset strategy that keeps you ahead of the game.
