Finding a Trusted Heat Pump Installer just got Easier
The heat pump industry is growing fast. But for homeowners, finding an installer they can trust isn’t always easy. Poor-quality installs damage trust across the industry, costing homeowners money and confidence, and harming the reputation of every installer working to do things properly.

That’s why Heat Geek, the leading name in heat pump training and system design, has partnered with Which? Trusted Traders, the UK’s consumer champion, to raise standards in the industry and help homeowners find trusted heat pump installers they can rely on.
Which? Trusted Traders is known for its rigorous approach to vetting businesses, ensuring homeowners can trust the people they let into their homes. At Heat Geek, we take the same approach with installer training, giving professionals the skills and knowledge they need to design and install systems that actually work, efficiently and effectively.
Together, we share a vision: an industry where quality is non-negotiable, where homeowners can trust the tradespeople they hire, and where the best installers are recognised for the work they do.
"By combining Heat Geek’s rigorous approach to training with Which?’s gold standard in consumer trust, we’re making it easier for homeowners to find skilled, reliable installers — and for great businesses to stand out."
