We offer all aspects of air and water, validation, commissioning and balancing services. Commissioning ensures the mechanical and electrical services of the building are operating in accordance with the design specification and provide the conditions intended by the designer and expected by the end user.

Our staff are dedicated and committed to our clients, many of whom have been with the company from the beginning and have a passion to fulfil their roles to the best of their ability.
Careful management and close attention to the needs of our clients has ensured repeat business from many large corporations within London, the South East and also nationally. Projects are undertaken from small single offices to large multifloor establishments. Our quotations are realistic and we have an excellent track record for completing projects on budget and on time, resulting on a very good working relationship and ongoing business with many clients.
