Best Boiler Brands

Best and worst boiler brands Below, we’ve collated the results of our annual boiler reliability survey and our annual boiler engineers survey. You can use our results to discover which brands are the most reliable, have the highest customer score, the best build quality according to boiler engineers, and are the most likely to be recommended by boiler engineers who aren’t paid to install boilers from that brand.  As you can see from our table, below, there’s a huge difference in overall score between the best boiler brands and the worst.
