From 01 November 2026, PTSG is bringing System Hygienics and Indepth Hygiene Services together as PTSG Specialist Fire Services Limited.
For customers, that means one specialist fire and ventilation partner, with the same trusted teams and more than 70 years of combined experience.
Part of PTSG’s Fire Solutions division, the new business combines specialist expertise with nationwide coverage, making it easier for customers to manage their fire safety and ventilation requirements.
Indepth brings over 40 years’ experience in specialist fire safety and ventilation hygiene while System Hygienics, established in 1993, has over 30 years’ expertise in ventilation and kitchen extract ductwork cleaning, fire damper testing and air hygiene surveys. Together, their teams deliver inspection, testing, cleaning, maintenance and remedial works across healthcare, education, hospitality, commercial property and the public sector.
Services include fire and smoke damper testing, ventilation and kitchen extract cleaning, fire compartmentation, fire stopping and indoor air quality testing.
Customers will continue working with the same teams and engineers they know. Existing contracts, agreed pricing and contractual obligations remain unchanged and services will carry on as normal.
Colin Harwood, Managing Director of PTSG Specialist Fire Services Limited, said: “Fire safety and building compliance rules are getting stricter, and property owners are carrying more responsibility and risk. Many want one trusted provider they can rely on rather than several suppliers to manage. Bringing System Hygienics and Indepth together gives them exactly that.
“The relationships our customers value will continue. They’ll work with the same engineers and contacts, with the combined capabilities of both businesses and the support of PTSG’s wider Fire Solutions division.”
