DHA Fire Stopping, the Weston-super-Mare-based specialist provider of passive fire protection and fire safety services, is accelerating its national expansion after recording around 20 per cent organic growth year-on-year for the past five years. The move is supported by investment in its team, fleet and two new compliance-focused services.
Founded in 2010, the business now employs a team of around 30 specialists delivering fire stopping, fire door surveying, fire protection inspections and compliance support for organisations managing large and complex building estates across the UK.

Recent contract wins include work for a global online retailer, a multinational technology company and a global real estate organisation, reflecting the growing demand for accredited, competence-led providers.
As part of its continued expansion, DHA Fire Stopping has invested in new Euro 6 fleet vehicles and confirmed a further £20,000 investment in professional training and development during 2026. The programme supports staff across the whole business, from administration and project teams to surveyors and site operatives, reflecting the company’s long-standing commitment to building an inclusive, highly qualified workforce in a traditionally male dominated industry.
The company’s growth is being driven by the post-Grenfell regulatory environment, in which building owners, duty holders and estates teams are under increasing pressure to demonstrate that fire safety is being actively managed.
In particular, Regulation 38 of the Building Regulations requires that accurate fire safety information is passed to the responsible person so a building can be operated safely once occupied, placing greater emphasis on the quality and accessibility of compartmentation, fire door and fire stopping records.
This month, the company is launching two new services in response to the latest regulations. One is trigonometry-based fire containment and compartmentation plans, which provide accurate, auditable building safety information. The other is CPD-accredited, in-person training delivered on site to support responsible persons and facilities management teams in managing fire safety across existing buildings.
Dave Alsop, Managing Director of DHA Fire Stopping, said: “Our growth has come from focusing on professional standards, ethical delivery and investing in our people. The investment we’re making in new services, vehicles and training reflects the way the industry is moving and the responsibilities our clients now carry.”
Steve Young, Operations Director at DHA Fire Stopping, said: “The expectations placed on building owners and estates teams have changed significantly over recent years. Organisations now need clear, accurate information about their buildings and the competence to act on it, not just at handover but throughout a building’s life.”
DHA Fire Stopping continues to support organisations across the UK in meeting their fire safety and compliance responsibilities within existing building estates. For more information, visit: www.dhafire.co.uk
