WarmZilla is here to take the hassle out of purchasing your new boiler. No more salespeople, hidden extras or waiting weeks for a new boiler. We wanted to give people the opportunity to go online and within minutes buy a boiler.

The founders have worked at every level of the industry and have built up over 25 years experience. With this experience they created the service they knew was lacking for customers. WarmZilla was born.

WarmZilla uses a network of Gas Safe installers who have passed our vetting process. We only send trained professionals in to your home.

The aim is to provide an easy, hassle-free service to buy your new boiler online. Our team, together with Derek the Dinosaur, strive to meet this aim every day.
