MEES Exemptions & the Seven-Year Payback Test: What Property Owners Need to Know
For commercial property owners, a building below the applicable EPC standard does not automatically mean every recommended improvement must be installed.
The non-domestic Minimum Energy Efficiency Standards (MEES) include several exemptions. One of the most important for portfolio owners is the seven-year payback test.
How does the seven-year payback test work?
A recommended energy-efficiency measure — or package of measures — fails the test when:
The expected energy-bill savings over seven years are less than the cost of purchasing and installing the measure.
Where this applies, the landlord may register a MEES exemption rather than undertake that particular improvement.
For example, if an improvement costs £50,000 but is expected to generate only £35,000 of energy savings over seven years, it would not meet the seven-year payback test.
What evidence is required?
This is not simply a desktop calculation.
To register a seven-year payback exemption, current government guidance requires:
three quotes from qualified installers;
confirmation that the landlord is satisfied the measure fails the test; and
the calculations demonstrating the result.
The exemption lasts five years. Once it expires, the landlord must reassess the property and attempt to improve its EPC rating again.
Why this matters across a portfolio
For owners managing tens, hundreds or thousands of properties, the challenge is determining which assets warrant detailed investigation first.
UpGreen can screen a portfolio to identify properties where exemptions may warrant further investigation and separate them from assets requiring active Capex planning.
In one 67-property mixed-use portfolio, this process identified 51 likely exemption candidates and 16 properties requiring active Capex attention, reducing the active retrofit requirement by more than 70%.

The formal exemption still requires the appropriate evidence and registration. UpGreen helps identify where that work should be focused.
What happens under the proposed 2031 EPC B standard?
In June 2026, the government confirmed its intention to introduce EPC B from 2031 for privately rented non-domestic buildings over 1,000 m² in England and Wales, where cost-effective.
Importantly, the government also intends to retain existing flexibility mechanisms, including the seven-year payback test and exemptions. The EPC B change is not yet in force and remains subject to secondary legislation.
For portfolio owners, this makes early triage increasingly valuable.
The question is not simply:
Which properties are below the target EPC?
It is:
Which properties require investment, which require further validation, and where might an exemption legitimately apply?
