EPC- upcoming changes to the Minimum Efficiency Standards (MEES) regulations


Assets are at risk of becoming stranded by the upcoming UK regulation changes.  Non-Domestic rented properties need to achieve a minimum of EPC C by 2027 & EPC B by 2030.  Domestic rented properties are required to achieve an EPC C rating by 2030.

Market research currently shows approximately 75% of Central London commercial building stock* does not comply so leaving existing landlords at risk.

Non-compliant assets will be liable for penalties:


Fine of up to £150,000, policed by Trading Standards and Environment Health Department

Charged per asset and is calculated by the size of the asset

Increases after 3 months


Fine of up to £4,000 for renting out a non-compliant property for more than 3 months

Charged per dwelling including flats

Publication on the PRS register

Prospective renters/purchasers unable to comply with the requirements for green mortgages


The following stages explain the Assessment Process and gives more information about Minimum Energy Efficient Standards.

STAGE 1 – Asset Compliance Assessment

EPC Assessment / The Minimum Energy Efficiency Standards (MEES)




This comprehensive design analysis will focus on long term value add strategies to reposition your asset at the forefront of the rental and sales market.

We will review the existing asset performance alongside lease periods, dilapidations and current refurbishment schedules to create a bespoke scope and programme of works to mitigate any rent free periods.

DAA have an extensive portfolio of comprehensive commercial refurbishments which maximise the sustainable performance of the existing buildings


Sustainable Passport

An EPC provides an initial metric for sustainable performance, but our combined service does not stop here.  It is focused on building a sustainable passport tailored to your asset.

As decarbonising the build environment becomes ever more critical, we will work within the framework of NABERS/LETI/BREEAM/WELL/BUILDING REGULATIONS to understand the core pieces of the existing asset and create a design pathway to achieve Net Zero.
