W4-EPC provides Energy Performance Certificate services for properties across the UK. The business helps property owners and agents comply with legal requirements when selling or letting residential and commercial buildings. Natural referral partners include estate agents, lettings agents, property developers, and conveyancing solicitors who regularly need EPC documentation for their clients. Surveyors and building consultants can also refer clients who require energy assessments. A referral to W4-EPC makes sense whenever a property transaction is underway and an up-to-date EPC is needed before marketing or completing a sale or tenancy agreement.
