Over the course of 65 years, HBS has established itself as a leading provider of mechanical, electrical and renewable solutions. The company has remained family run throughout its growth and is dedicated to delivering the highest levels of quality, service and reliability.

HBS was first set up by Harry Bull in 1950, providing plumbing and heating services across Hampshire. More than six decades on, his son Kevin has taken the company to where it is today, a leading provider of building services, specialising in fully-integrated solutions. This expansion has been made possible with the help of his sons, James, Alex and Charles, who continue to work alongside him.

We have developed a wealth of experience in developing and implementing mechanical, electrical and renewable solutions for the new build, commercial and public sectors. This has been matched with an assured reputation for quality, service and reliability. Today, many of the UK’s major developers, contractors, social housing providers and blue-chip companies choose us as their preferred contractor of choice.

Why choose HBS?


Depending on your project requirements, we can deliver mechanical, electrical and renewable services in isolation or as part of an integrated solution. By having interlinked divisions operating under one roof, we can guarantee a more effective transition through each phase of your project. It also means stronger communication channels are in place to ensure a smoother project completion.

We design and install bespoke solutions, delivering on time and on budget, no matter what size the project is. Furthermore, through key relationships with industry leading manufacturers, we can price competitively, delivering maximum value.
