Energy Performance Certificates (EPCs) for Commercial Buildings

An Energy Performance Certificate (EPC) is a legal requirement for commercial and public buildings in the UK when they are constructed, sold, or let. It provides a rating of the building’s theoretical energy efficiency and is a key part of your organisation’s energy compliance obligations.

Compliant, Strategic EPCs for Commercial and Public Buildings

At Arthian, we deliver EPC assessments as part of our wider energy compliance consultancy. Whether you need a single certificate or a coordinated strategy across a large property portfolio, we ensure your buildings are compliant, efficient, and aligned with your sustainability goals.

What Is an EPC?
An Energy Performance Certificate rates a building’s energy efficiency on a scale from A (most efficient) to G (least efficient). It is based on the building’s construction, services (such as heating and lighting), and energy use assumptions.

When Is an EPC Required?
You must have a valid EPC if:

You are selling or letting a commercial property
A building is newly constructed or modified
You are applying for funding or grants linked to energy performance
You are required to comply with Minimum Energy Efficiency Standards (MEES)

EPCs are valid for 10 years and must be lodged on the national register.

What’s Included in an EPC Assessment?

Our EPC service includes:

A site visit by a qualified non-domestic energy assessor
Data collection on building fabric, HVAC systems, lighting, and controls
Energy modelling using approved software
Issuance of an EPC with a rating from A to G
Lodgement on the national EPC register

We also provide a recommendation report outlining cost-effective measures to improve your rating.

Why EPCs Matter

Legal Compliance: EPCs are a statutory requirement under the Energy Performance of Buildings Regulations. Non-compliance can result in fines and enforcement action.

MEES Compliance: to let a commercial property, it must meet a minimum EPC rating of E under the Minimum Energy Efficiency Standards. Arthian can help you assess risk and plan improvements.

Asset Value: a higher EPC rating can enhance the value and marketability of your property, making it more attractive to tenants and buyers.

Sustainability: EPCs support your organisation’s environmental goals by identifying opportunities to reduce energy use and carbon emissions.

Frequently Asked Questions (FAQs)

How long is an EPC valid for?
An EPC is valid for 10 years unless the building undergoes significant changes that affect its energy performance.

What happens if I don’t have a valid EPC?
You may face fines and enforcement action. Letting or selling a property without a valid EPC is a breach of regulations.

Can I improve my EPC rating?
Yes. Our recommendation report outlines practical steps to improve your rating. We can also support implementation through our consultancy services.

Do I need an EPC for each building I own?
Yes, if the building is being sold, let, or newly constructed. We can help you assess which buildings require EPCs and manage the process across your portfolio.
