Welcome to our website and thanks for taking the time to find out more about our company!

Octagon were established in Bristol in 1963 providing a quality local service supplying and installing warm air and radiant heating.

Back then we were one of the first companies to achieve CORGI registration!
Over the years the company has grown and changed to become one of the South-Wests leading mechanical companies, and indeed now work all over the UK from our Head Office in Bristol.

We have been proud from those early years through to today to focus on top quality service and technical ability, constantly investing in training and technology to keep our engineers at the forefront of the industry. We are currently investing into developing our Renewable Energy division and see this as being a major part of our future business as the way the world works changes. In view of this, in 2010, recognising the ever expanding range of services we provide, and the fact that heating is now just a part of those services, we re-branded as OHS Services.

Over the years we have worked for many of the most prestigious companies and organisations in the UK, from blue chip construction companies, retailers, water authorities, church diocese, privates schools and the like, as well as our design and install involvement on many luxury private residences.
Our client base ranges from small local organisations and businesses as well as large corporations, and many of these have annual service contracts in place to ensure their servicing and maintenance needs are fully and professionally met.
We are not here to constantly look for new customers, but, as we have done since 1963, to have on-going relationships that last for years, based on service, expertise and reliability! We would now love to be able to demonstrate the wide breadth of skills and services we can offer to yourselves too.
Elsewhere on this website you will find the range of services we provide, which range from service contracts through to major new build mechanical installations.

Whatever your needs, please contact us today to discuss with a member of staff, and we look forward to working with you.

THE OHS VISION! - TO PROFESSIONALLY CREATE AND MAINTAIN YOUR LIVING AND WORKING ENVIRONMENT!
