Through detailed EPC surveys and expert technical advice, our experienced team of commercial Energy Performance Certificate (EPC) assessors can help improve the energy efficiency of non-domestic properties and ensure compliance with energy performance certificate regulations.
Energy Performance Certificate Regulations
An Energy Performance Certificate (EPC) is legally required whenever a building is constructed, modified, sold, or let.
Only an accredited energy assessor can carry out an EPC survey and lodge valid EPC reports. They will rate the building from A (most efficient) to G (least efficient) and recommend measures for improvement.
All EPCs are valid for 10 years and should be made available to any prospective buyer or tenant. You must also display your certificate by fixing it to your commercial building if it has a total useable floor area of over 500 square metres and is frequently visited by the public.
The penalty for non-compliance is a fine between £500 and £5,000 based on the rateable value of the building.

Commercial Energy Performance Certificate Ratings Explained
Your commercial Energy Performance Certificate (EPC) will tell you how energy efficient the building is on the scale A (very efficient) to G (inefficient). It will also show how costly the building is to heat and light, as well as its current and projected carbon emission levels.
Following an EPC survey, the EPC assessor will provide a full EPC report outlining:
- The estimated energy costs of the property over 3 years
- The energy efficiency rating (current & potential)
- A summary of the property’s energy performance-related features
- Actions that can be taken to save money & improve efficiency
- The costs of potential improvement strategies against future savings
- A carbon dioxide (CO2) rating (current & potential)

Frequently Asked Questions
What is an EPC survey?
An Energy Performance Certificate survey (EPC survey) determines the energy efficiency of a building. It involves assessing the property's performance-related features (e.g., insulation, lighting, and heating) to produce a certificate of energy performance. You will need an EPC for any domestic or non-domestic building being sold, let, modified, or constructed.
What are the EPC rules for commercial property?
In the UK, commercial properties must have a valid Energy Performance Certificate (EPC) when they are built, sold, or let. It is currently a legal requirement that any commercial property being let must have an EPC rating of E or above, unless an approved exemption has been registered.
How often do you need a commercial EPC?
A commercial EPC is valid for 10 years. However, you will need new EPC reports whenever you make significant changes to a building that could affect its energy performance (e.g., alterations to heating, lighting, insulation, or layout). You’ll also need an up-to-date Energy Performance Certificate (EPC) rating whenever the property is put on the market or offered for lease.
What are the benefits of commercial EPCs?
Energy performance certificate companies specialising in commercial EPCs can advise you on how to assess, improve, and maintain your rating, helping you:
- Ensure you meet legal requirements & avoid penalties
- Identify ways to reduce energy use & lower costs
- Make your property more attractive to tenants & buyers
- Stay ahead of future energy efficiency regulations
- Improve your building’s environmental performance
Who can carry out an EPC survey?
EPC surveys must be carried out by an accredited energy or EPC assessor, which you can find via the government’s official EPC register.
Is an EPC survey disruptive?
The EPC survey itself is non-intrusive and will not damage the building. However, an Energy Performance Certificate (EPC) is thorough and requires access to all areas of the property. The size and ease of access will determine how much time the EPC assessor will need.
Where do you get an energy performance certificate?
You can get a commercial Energy Performance Certificate survey (EPC survey) through a qualified energy assessor, like ACI Reports.
