For business owners, property managers, and landlords in London, a Commercial Energy Performance Certificate (EPC) is a legal requirement. It assesses the energy efficiency of your commercial property and ensures compliance with UK regulations. Understanding the rules, costs, and process is critical to avoid fines and improve your property’s value.
What is a Commercial EPC?
A Commercial EPC measures energy efficiency for non-residential properties, including:
Offices
Shops & retail spaces
Warehouses
Industrial units
It provides:
Energy efficiency rating (A–G)
Estimated energy costs
Recommendations for improvement
Unlike domestic EPCs, commercial assessments often require detailed energy modelling.
