Who we are

We’re a fast-growing integrated engineering, environmental and building consultancy. We’re currently doubling in size year on year through strategic business acquisitions and organic growth.

Our journey began in energy assessment and testing services but now includes building services design, building control and our original building compliance offering. The combined experience of the Group exceeds 50 years, so we fully understand the complexities you may face during the construction cycle.

Although the Group is continuously developing, we are a collective of SMEs, allowing us to offer a full suite of services without compromising on service quality or standard of work. When you choose us, you get the Group benefits of security, knowledge, UK-wide coverage and availability of staff, but also the advantage of SMEs: flexibility, quick decision making, entrepreneurial thinking and modern methods of working.

Our clients always come first in our solutions-focused approach and we care about the projects we work on, always seeking the best outcomes for you, whether that’s saving you time and money or increasing your project’s sustainability and environmental performance.


Our mission is to provide the highest level of integrated services, going above and beyond to make our clients’ lives easier, reduce costs and ensure their construction projects are a success with the help of our knowledgeable employees that care.


Our vision is to be one of the most progressive building consultancies in the UK. By 2025 we will provide a full suite of construction consultancy services and employ over 300 like-minded passionate experts.

When a company joins C80 Group, we always aim to protect the legacy and brand values of the existing business whilst growing it alongside the other C80 firms.

We always look to retain and work closely with existing management teams to ensure a smooth process and protect existing employees.

The services provided by each company are designed to work seamlessly alongside each other, so a client of one company can easily become the client of another in the Group.
