The Building Compliance Testers Association (BCTA) and Cleaner Safer Group (CSG) formally merged on 2 March 2026, bringing five certification and compliance schemes together under a single governance structure. 

CSG is the parent organisation of HETAS and Woodsure – two well-established certification bodies in the solid fuel and biomass sector. HETAS run the UK’s only UKAS-accredited competent person scheme specialising in solid fuel and biomass, and Woodsure is the UK’s only wood fuel quality assurance scheme. 

Like BCTA, both HETAS and Woodsure are built on rigorous standards, consumer protection, and a genuine commitment to their members – making this a natural and complementary partnership. 

Both BCTA and CSG continue as legal entities, and members across all schemes will see no changes to their day-to-day registration or membership. This merger grants BCTA access to CSG’s established governance, IT systems, and quality infrastructure – creating a more resilient organisation with more resource to invest in members and quality. 

Future of The Building Performance Hub 

As part of the merger, The Building Performance Hub in High Wycombe will work with HETAS, sharing its experience and knowledge to support HETAS with future training developments. The intention is for the facility to operate as a development centre – a dedicated environment to research, trial, and refine course content – representing a significant investment in the expertise and facilities already established within BCTA. 

This will allow any developments to be implemented nationwide across the existing network of HETAS Approved Training Centres, ensuring continuous improvement and a commitment to the highest standards. All improvements would be rolled out across the whole network, so candidates receive the same high standard of training no matter where they are learning. 

Barry Cope, CEO of Cleaner Safer Group, said: “BCTA is an organisation built on genuine expertise, strong values, and a real commitment to its members. Being part of bringing these two groups together feels like a natural next step, and I’m genuinely excited about what we can achieve together.” 

Kaye Welfare, Chair of Cleaner Safer Group, added: “This is an exciting step forward for both organisations. By coming together, we can offer greater support, improved services, and a platform that benefits everyone – from existing registrants to the wider industries working in the built environment.”
