Commercial Energy Performance Certificates (EPCs) in London

If you own, lease, or manage a commercial property in London, a valid Energy Performance Certificate (EPC) is not just good practice—it’s a legal obligation. At We Know How, we offer expert Commercial EPC assessments throughout London, including Clapham, Brixton, Balham, and beyond.

Whether you run a retail unit in Battersea or manage offices in Southwark, our accredited energy assessors deliver reliable, fixed-cost EPC reports that help keep your business compliant—and more energy efficient.

What Is a Commercial EPC and Why Is It Required?

A Commercial EPC evaluates the energy efficiency of a non-domestic property, giving it a rating from A (most efficient) to G (least efficient). You’re legally required to have one if:

You’re selling or leasing commercial premises
You’re modifying or constructing a commercial building
Your property has been recently split or merged

Not having a valid EPC can result in fines of up to £5,000. Our local surveyors help you avoid unnecessary delays and penalties by producing compliant reports quickly and accurately.

What’s Included in a Commercial EPC Survey?

Our commercial EPC assessments cover all essential aspects of energy performance, including:

Building fabric, layout & orientation
Heating, ventilation & cooling (HVAC) systems
Lighting systems and energy usage
Insulation and glazing
Use of renewable energy technologies
Zoning and occupancy details

You’ll receive a digital EPC report within 48 hours, alongside clear, tailored recommendations to improve your building’s energy rating and reduce operational costs.
