MEES, EPC Ratings and Roof Coatings: An Honest Guide

Q: Will a roof coating improve my commercial EPC rating?

Rarely on its own. Commercial EPCs are driven mainly by insulation, heating, controls and lighting. A reflective coating can support thermal performance and protects the roof, but confirm any contribution with your EPC assessor.

Q: Is EPC C compulsory for commercial property by 2027?

Not at the time of writing. The enacted minimum for most commercial lets in England and Wales is EPC E. EPC C has been consulted on but is not law.

Commercial landlords are being sold roof coatings as an EPC fix. Here is what a coating genuinely can and cannot do for MEES compliance, without the sales gloss.

Where MEES actually stands

Under the Minimum Energy Efficiency Standards (MEES), it has been unlawful since April 2023 to continue letting most commercial property in England and Wales with an EPC rating below E. The government has consulted on tightening this, with EPC C discussed for the late 2020s, but at the time of writing the C requirement is a proposal, not law. Beware of anyone selling work on the back of a deadline that has not been enacted. What is certain: energy performance expectations for commercial lets are moving in one direction, and planned improvement beats panic spending.

Straight answers

A coating is roof protection first, energy measure second

What a coating CAN doA reflective (cool roof) coating can reduce solar gain and summer overheating, protect the roof substrate, and extend the life of the existing roof while you plan bigger works.

What it RARELY does aloneAn EPC band is driven mainly by heating, insulation, lighting and building services. A coating on its own seldom moves a commercial EPC by a full band.

What actually moves an EPCInsulation levels, heating plant, controls and lighting carry most of the weight in a commercial EPC (SBEM) assessment. A coating can support the case; it is not a substitute.

The honest route

How to plan this properly

Start with the roof condition, not the EPC certificate. If the roof is weathered, a survey will tell you whether a coating, repairs or replacement is the responsible route, and a reflective system can be specified where it genuinely helps the building. Then have your EPC assessor confirm what any proposed work contributes before you spend on compliance grounds.

Common questions

MEES and roof coatings

Will a roof coating improve my commercial EPC rating?

Rarely on its own. Commercial EPCs (SBEM) are driven mainly by insulation, heating, controls and lighting. A reflective coating can reduce solar gain and support thermal comfort, and it protects the roof itself, but treat any claim that a coating alone delivers an EPC band jump with caution and confirm with your assessor.

Is EPC C compulsory for commercial property by 2027?

Not at the time of writing. The legal minimum for continuing to let most commercial property in England and Wales is EPC E (since April 2023). EPC C has been consulted on for the late 2020s but is not enacted law. Planning ahead is sensible; spending in a panic over an unenacted deadline is not.

What is a cool roof coating?

A light-coloured or reflective coating that reflects more solar energy than a dark weathered roof, reducing surface temperature and summer heat gain inside the building. On suitable substrates it also restores weather protection. Whether it is right for your roof depends on the condition found at survey.

Survey first, compliance second

A real surveyor inspects your roof, sets out the honest options in writing, and you take that to your EPC assessor with confidence.
