Who We Are
AssessPlus provides professional EPC and retrofit assessments across London and Essex, helping landlords, homeowners and property professionals stay compliant, improve energy performance, and plan property upgrades with confidence.
The business was founded to offer a more reliable, transparent and efficient alternative to traditional energy assessment services.
