Minimum Energy Efficiency Standards (MEES)
The UK government is consulting on proposals to further raise the minimum energy efficiency standard for rented buildings to an EPC band rating of 'C' by 2027 and to a Band rating of B by 2030.
This initiative aims to reduce carbon emissions and address fuel poverty. The consultation, which seeks feedback on these proposals, is open until 2 May 2025 for more information go to Reforms to the Energy Performance of Buildings regime - GOV.UK.

What is changing?
Since 2008, there has been a requirement for providing an Energy Performance Certificate (EPC) on the sale, rent or construction of a non-domestic building with a floor area greater than 50m2.
The certificate utilises an A to G scale / banding to demonstrate the efficiency of the building. Historically landlords only had to comply with producing an in-date EPC, however in the UK, the Minimum Energy Efficiency Standards (MEES) regulations were released in 2018 to improve the energy efficiency of privately rented properties.
Since this time, landlords have been prohibited from granting new tenancies for properties with an EPC rating below 'E'. This requirement extended to existing tenancies on 1 April 2020. Properties rated 'F' or 'G' cannot be legally rented out unless a valid exemption is registered.
How to achieve the new ratings
These evolving standards underscore the government's commitment to enhancing energy efficiency in the buildings sector, aligning with broader environmental goals. To achieve band C and above, there is a need for the introduction of low carbon technology measures.
Common solutions include:
- changing to LED lighting,
- installing / Improving building insulation,
- replacing fossil fuel boilers with a low carbon options e.g. heat pump,
- installing solar PV panels.
How can we help you?
Through our understanding of building design, construction and facilities management, Robertson recognises that a combination of these types of solutions would be required to ensure compliance typically.
Working with an experienced and trusted partner such as Robertson Group will provide support your organisation to achieve compliance with these new regulations.
Whilst it is recognised that landlords may need to invest in these low carbon technology measures going forward, there are significant positives.
- Maintaining rental income on owned properties.
- Improving the building and as associated services reducing asset lifecycle, operation and maintenance costs.
- Making the building more attractive to current / future tenants due to the improved environmental performance of the building and or reduced utility costs.
- Avoiding the £5,000 per property fines for non-compliance to MEES.
