About Brennan & Son
Brennan & Son is a family plumbing and heating business based in Southampton, founded in 1985 by Derek Brennan. The business offers boiler repairs, servicing and replacements, central heating installations, unvented cylinder installations, kitchen and bathroom plumbing, gas safety inspections, and repairs to gas cookers and fires. Minor plumbing repairs cover blocked toilets, dripping taps, slow-draining waste pipes and water leaks. Powerflushing removes sludge from pipes and heating components that restricts water flow.
The team includes gas engineers and plumbers at various stages of training. Sarah joined in 2002 to oversee expansion, and Heather started a plumbing apprenticeship in 2025 as the third generation in the business. Demian has been with the business throughout his working life. Akbar previously worked as a British Gas service engineer. Brent worked on LPG boilers in mobile homes. Karl is a gas engineer and plumber. Amaan, Ellis and Luke completed plumbing apprenticeships with the business to gain gas qualifications. The office team includes Nataliia, Diane and Diamond in administration roles.
Brennan & Son serves Southampton and carries out boiler fault finding, heating system advice, kitchen and bathroom installations using copper pipework, and gas appliance servicing. The Gas Safe Register recommends annual boiler servicing for all boilers.
