Taking the Key

Homeowners, Tenants & Letting Agents

We work closely with many landlords, letting & estate agents assisting them with EPC assessments, & MEES Surveys advising clients on potential energy efficiency measures to be installed to ensure they are compliant with government legislation when renting or leasing out a property.

When selling a property a valid EPC is required to be produced if the property does not already have one. EPC’s have a ten year lifespan.
