Improving the EPC rating of your commercial building can make the difference between successfully leasing the property or facing fines of up to £150,000.

Fortunately, significant improvements to the score can often come from conducting an air tightness test and including these results in the final calculation, replacing default data that often negatively skews the results.

Commercial EPC ratings will become increasingly important to improve as we head nearer to 2030 and local authorities ramp up their net zero ambitions.

Our commercial energy assessors can advise on the best way to carry out an energy assessment and what actions can be taken to improve the final EPC rating.

Why work with us?


Our sustainability consultants have extensive experience in meeting regulatory requirements, yet work hard to go beyond mere compliance with the building regulations.

We pride ourselves on delivering decarbonisation advice to help our clients build lower carbon, energy-efficient properties.


We reduce the amount of assumed data in each calculation to the bare minimum, meaning that your EPC calculation is as accurate as possible.

Conversations with clients are key to this process and our work improves each time we work on a new project, thanks to the collaborative approach we adopt with our clients.


Our office-based staff work hard to book all appointments as quickly as the delivery schedule allows.

We work on a two-week schedule, with the vast majority of commercial EPCs being delivered well within that window.


Our rate card prices for all services are reviewed regularly, so we’re confident that you won’t find a better service for a better price anywhere else.

If you think you’ve found one, we’ll either beat or match it.


Navigating the complexity of energy efficiency, decarbonisation, and building regulation updates isn’t easy. We’ve worked hard to explain a range of topics related to commercial decarbonisation in plain English to help non-experts get the information they need.
