The Warmer Group works closely with local authorities, social housing providers, and private landlords to improve the energy efficiency of rental properties and help achieve higher Energy Performance Certificate (EPC) ratings.
We specialise in cost-effective insulation measures such as Cavity Wall Insulation and Loft Insulation, both of which can make a significant difference to a property’s heat retention, running costs, and overall EPC rating.
Under the Minimum Energy Efficiency Standards (MEES), it remains a legal requirement that privately rented properties in England and Wales must have a minimum EPC rating of E before they can be legally let, unless a valid exemption applies.
The government has also consulted on proposals to raise minimum EPC standards in the future (potentially to C rating targets in the coming years), meaning improving energy efficiency now can help future-proof rental portfolios.

Improving insulation is one of the most effective and affordable ways to increase a property’s EPC rating.
We provide:
By improving insulation levels, landlords can often achieve a noticeable EPC improvement, helping properties remain compliant while also reducing tenant energy bills and improving comfort.
We understand the challenges landlords face with compliance, rising energy standards, and tenant expectations. Our goal is to provide practical, cost-effective solutions that improve property performance without unnecessary disruption.
