/ Minimum Energy Efficiency Standards (MEES)


MEES was introduced in March 2015 under the Energy Efficiency (Private Rented Property) (England and Wales) Regulations 2015, to specifically tackle energy inefficiency in the UK’s poorest performing building stock – and the wider aim of contributing towards the UK’s longer term national carbon reduction targets. The structure of MEES was developed to overcome the traditional barriers to the implementation of energy efficiency works in let properties, through a robust legislative approach.

Penalties for Non-Compliance

Failure to comply with the MEES regulations will result in a financial penalty and publication of non-compliance. Financial penalties will be based on the rateable value of the property in question, with a maximum fine of £150,000 per asset.


Ability to market impacted properties or demises will be impossible if they are not upgraded.
Risks to cashflow from revenue generating portfolios.
Likely reduction in the capital value of impacted properties.
Significant implications for rent reviews and dilapidation assessments with existing tenants

The average lease length is now 7.2 years with two-fifths of leases having a break clause, allowing the lease to be terminated early*. Given that after 1st April 2018, the MEES regulations will be activated when a new tenancy is signed, the turnover of tenants will also impact the number of buildings which must be improved.

Our consultants will review your EPC portfolio and the status of your tenancies. We will then assess your level of risk and provide a quotation of a MEES assessment if required. We will guide you through the most appropriate route to compliance and ensure any sites which fall within PRS exemptions are reported to BEIS register.
