Guild Patrons
Guild Patrons are a small, select group of organisations that support this entire initiative. Their role is not to influence the content but to enable the spread of good information.
Being a Guild Patron signifies a commitment to the growth of a skilled, knowledgeable, and transparent heating sector.
Castrads
When the internet opened up for retail, it brought a flood of radiator sellers. Unfortunately, the quality of some of the cast iron radiators my customers bought was genuinely shocking. While they often looked beautiful on the surface, they frequently suffered from internal metal flaking, which inevitably led to problems in the overall heating system.
Another perennial issue, and one that sadly persists today, is sellers of all types of radiators over-quoting the heat outputs of their radiators.
That’s why I'm pleased to have UK Castrads onboard. They are a family business absolutely devoted to quality, not just appearance. They're used by some of the best heating engineers I know, and it's a pleasure to have them as a Guild Patron.

Primary Pro is the brainchild of my friend, Dave Smith, who's been a massive supporter of the work I do. Dave saw a need for better external pipework and has helped the heating industry understand how to correctly insulate and seal it. He's also helped the industry understand pipe insulation in general. Stuff people hadn't been thinking about. Dave is committed to life long learning and is great in helping other engineers understand the benefits and importance of professional development.

Renewables Centre
The Wolseley Group Renewables Centre is a new, nationwide initiative launched by the Wolseley Group (which includes Plumb Centre) to support plumbing and heating professionals in transitioning into the growing low-carbon heating and renewables market.
It is designed as a one-stop solution that addresses the main barriers installers face: training, technical complexity, and the MCS accreditation process. I'm looking forward to the exciting things I can do to help the Wolseley Group and it's a pleasure to have them help me with the Guild.
Becoming a Patron
By becoming a Patron, you can actively fund the creation and dissemination of engineer-led case studies, helping to break down silos and raise standards across the entire heating industry.
They are seen as collaborators in a crucial mission: to create a trusted source of truth that benefits everyone from homeowners to policymakers.
As Chris Stark has expressed:
"Nathan is one of the UK's clean heat leaders, so I always watch him closely. This collaborative media venture is an exciting next step. We need positive voices like Nathan's to help broaden knowledge around retrofit and heat pump installations."
