Your building is EPC E. Here's what that actually means for letting it
MEES turned energy performance from a nice-to-have into a legal condition of letting. What the rules require, what the work costs, and when to do it.

Most landlords I speak to know their EPC rating. Far fewer have worked out what it now stops them doing.
The Minimum Energy Efficiency Standards regime made energy performance a condition of letting rather than a piece of paperwork. A sub-standard building cannot lawfully be let, and the standard has been tightening. That turns an aesthetic decision into a legal one — and a building that cannot be let is a building that cannot earn.
The practical position
If you own commercial property and the rating is weak, you have three options and only one of them is good.
- Do nothing and hope. Your building sits empty or you carry enforcement risk. Neither is cheap.
- Wait until the tenant leaves and rush it. You pay a premium for speed and you lose rent during the works.
- Do it in a planned void, alongside a Cat A refresh you were going to fund anyway. Half the cost, none of the panic.
The third option is available to nearly everyone and almost nobody takes it, because energy work gets deferred until it becomes urgent.
What the work usually is
People imagine solar panels and heat pumps. Usually it is far less dramatic.
- Lighting — swapping to LED with proper controls is the fastest, cheapest single improvement in most buildings
- Heating and cooling controls — often the plant is fine and the controls are the problem
- Fabric — insulation where it is accessible, draught sealing, glazing where it is genuinely failing
- Metering and building management, so the improvements are actually evidenced
The order matters. Doing the cheap, high-impact items first often gets you over the line without touching the expensive ones.
The number
For a typical older office floor, moving from a weak rating to a compliant one usually sits in the low tens of thousands rather than the hundreds. It is almost always less than one void period.
When to do it
Now, if the building is empty. At the next break or expiry, if it is not. The worst time is when a tenant is signed and waiting.
Get it assessed before your next void, not during one. We survey the building, tell you what the rating costs to fix, and do the work — and if it makes more sense to combine it with a Cat A refresh, we will say so.
