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


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

Research currently shows approximately 75% of Central London commercial building stock* does not comply leaving existing landlords at risk.  Darling Associates, in partnership with PSH and Dalbergia provide a bespoke MEP, architectural and cost service to review assets and wider portfolio performance to highlight buildings at risk and a sustainable route to compliance.



Non-compliant assets will be liable for penalties:

▪ Publication penalty and/or 10% of the rateable value of the property up to £500,000 from local authority for renting out a non-compliant property for less than 3 months.

▪ Publication penalty and/or 20% of the rateable value of the property up to £150,000 from local authority for renting out a non-compliant property for more ant 3 months.

▪ Stranded asset – unable to lease or sell the property without penalty.

Alongside this your asset will be stranded in an ever growing commercial landscape:

▪ Inability to raise ESG focused funding

▪ Diminish asset value and low tenant interest due to poor sustainable fundamentals

▪ Inability to charge premium rental rates due to poor performance

▪ Higher energy and running costs due to poor building performance

▪ Unable to achieve corporate compliance



Asset Compliance Assessment Report:

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 building performance, but our combined service does not stop here. It is focused on building a sustainable passport tailored to your asset.

As decarbonising the built 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.
