Energy Performance Certificates (EPC) in London
EPC assessments and energy ratings for landlords, letting agents, rental properties, and managed portfolios across London.
Energy Ratings for Landlords and Rental Properties
An Energy Performance Certificate explains how energy efficient a property is, gives it an A to G rating, and includes recommendations that may help improve efficiency and reduce typical energy costs.
Landlords usually need a valid EPC before marketing a property to rent. Wasser Group helps landlords, agents, and property managers arrange EPC assessments across London for individual rental homes, HMOs, and managed portfolios.
Once the assessment is complete, the EPC can be used to show prospective tenants the property rating and to support landlord compliance records.

What the EPC Assessment Covers
The assessment records the main features that affect the property's energy rating.
Heating and Hot Water
Boilers, heating controls, hot water systems, and fuel type are reviewed as part of the energy performance calculation.
Lighting and Recommendations
The EPC includes the current rating, potential rating, typical energy costs, and recommended improvements where applicable.
Who Needs an EPC Certificate?
An EPC is needed when a property is sold, rented out, or newly built, unless an exemption applies. Landlords should order an EPC before marketing a rental property to prospective tenants.
- Private landlords preparing a flat or house for rent.
- Letting agents listing rental properties in London.
- Property managers coordinating EPCs across portfolios.
- Owners checking whether an older EPC has expired.
When Should It Be Renewed?
An EPC is valid for 10 years. You may need a new EPC if the existing certificate has expired, if the property is not on the register, or if energy improvement works mean the rating may have changed.
Privately rented properties covered by minimum energy efficiency rules generally need to meet at least EPC band E unless a valid exemption applies.
