What are the Minimum Energy Efficiency Standards?

It is unlawful to let residential or commercial properties with an EPC Rating of F or G.

MEES Compliance


Data from the National EPC register indicates that 18 percent of commercial stock has EPC ratings of F or G and another 20 percent are rated E. The Minimum Energy Efficiency Standards, or MEES, apply from April 2018. The government currently has a white paper in consultation to lower the minimum standards to a C by 2027 and a B by 2027. 

The measures to improve the rating must be cost effective. In commercial properties, the cost for installing the measures must be less than measure will save over a 7 year period. This is where NRG Assessments can help. In residential settings there is a cost cap of £3500, this is the maximum a landlord would be expected to pay.

Be Proactive not Reactive

The onus is on Landlords. If you have a large or small portfolio contact us to see if your property will meet this new criteria. We will analyse your property and also help you make cost-effective improvements.

Sales are not caught by the legislation; only leases. By 2023 all leases will be included: current and new. This will increase the demand for EPCs. Be proactive not reactive as this could have a huge financial impact.



The Commercial MEES Assessment Process

EPC Assessments


Attend site and completed the desk-based computer model as normal together with the recommendations to improve the energy efficiency of the building.

MEES Analysis


The EPC will be thoroughly checked and if it achieves an A-E it will be lodged as normal. If it achieves an F or G you will be informed and the next part of the assessment can be discussed.

MEES Reporting


Once you have agreed further analysis we will upload your EPC onto Arbnco's platform for them to analyse the recommendations made in the EPC.

MEES Savings


The report highlights cost-effective savings over a 7-year period, If the cost for installing a measure to improve the building's energy performance is less than the 7-year saving then these will have to be installed. If not, then it can be exempt from being installed.

If a boiler saves the occupant £3000 over a 7-year period, but costs £3001 or higher. EXEMPT

If the boiler costs £2999 or lower. NOT EXEMPT

MEES Quotes


For an exemption to comply with the regulations, a minimum of 3 quotations are required. For the cost-effective measure to be installed it must be less than the 7-year saving.

MEES Completion


If some elements have been installed to increase the energy performance of the building, our assessor will revisit to check and validate the measure installed in the building.

The EPC can be finished and if an exemption is required the EPC will be lodged together with the MEES report and the quotations to the government's exemption website.
