Since 1950 HBS Group Southern has established a strong reputation for consistently delivering quality and value every time for clients.

Founded in 1950 by Harry Bull, HBS began as a plumbing and heating contractor providing specialist services across Hampshire. More than seven decades on, his son Kevin has taken the company into an industry-leading mechanical, electrical and renewable energy specialist contractor. This expansion has been made possible with the help of his sons, James, Alex and Charles, who continue to work alongside him.

With an assured reputation for consistently delivering quality, service excellence and value, the award-winning business has built a wealth of experience and expertise in the new build housing, commercial and public sectors. This has seen many of the UK’s residential housing developers, construction companies and blue-chip companies choose HBS as their trusted mechanical and electrical building services partner time and time again.

We have the in-house expertise to manage projects from consultancy and design through to installation and aftercare, providing an end-to-end service tailored to specific project needs. By offering a complete package of mechanical, electrical and renewable heating installation services, we believe this allows our clients to partner with one specialist provider who can save them time and money in the procurement and delivery process.
