Efficient and tidy fitters.
Our boiler was fitted on the second attempt after the first fitter broke down on route. The men were prompt and efficient fitting the new boiler and left the place tidy. Unfortunately as yet the boiler doesn't seem to be running as often as we'd like and I've yet to understand it. I have worked out how to put it on for a few hours which helps but more research is needed. I've looked at the hub but not found information yet.

Super quick. Kept informed. The engineer (Marcos) was outstanding in every way. Professional, polite, helpful, patient and highly skilled. Incredible how much he achieved in less than 2 days and left our house better than he found it (thanks for taking out some other old pipes). Can't recommend WarmZilla and especially Marcos enough. Many thanks.

Good value service
We had ongoing issues with our boiler and struggled a bit with contacting Warmzilla, however once we had established communication an engineer was found and came to us within a day, and our agent was extremely helpful. A good service for the price we pay.

A company that gets customer service
A company that gets customer service. If only all companies were like Warmzilla. Just made my second major purchase with them of air con having bought a boiler off them before. I also have a boiler cover policy with them. Their prices cannot be beaten - lowest to be found but they operate a price match in the unlikely event that you find a better price - and their customer service is phenomenal. Nothing is too much for them. They respond quickly and professionally to any query you raise. They really are my go to company for the household items they offer and they should be yours too!

Let down by British Gas, but Warmzilla didn't disappoint!
British Gas had let me down when it came to providing a quote so I thought I'd go directly to the manufacturer for a price.
Warmzilla are the national installation partners for Worcester Bosch and their pricing was very competitive and the agent I dealt with (Kian) for the quote and survey (via a WhatsApp video call) was helpful, efficient and in no way overbearing or pushy for me to go ahead with the quote.
On the day of installation, everything went smoothly and the engineer that fitted the boiler was very tidy, friendly and professional, making sure that everything was left working as it should and made sure to answer any questions I had.
All in all, this was a first rate service and I would recommend them to friends and family and also use them again if the need arose.

I recently had an EV charger installed by Warmzilla, and the entire experience from start to finish was exceptional. Communication was top tier throughout the process—I’ve honestly never experienced such high-quality customer service and aftercare.
From the initial contact, to arranging the appointment, and through to the installation itself, everything was handled in a professional and efficient manner. The installation was first class, and the team made the whole process smooth and stress-free.
Warmzilla truly sets the standard for how this type of service should be delivered. I wouldn’t hesitate to recommend them.

Extremely Disappointed
Extremely Disappointed – Avoid if You Value Reliability and Safety
The ordering process was quick and easy, but everything after that was a nightmare. The installation was delayed by six weeks, with the engineer failing to turn up on four separate occasions. Each time I was promised a call back from customer service, but none ever came.
When the boiler was finally installed, the work was sloppy and unsafe — the chimney wasn’t fitted correctly, and the electrics were poorly done. Because of the chimney issue, smoke entered my home and made my family ill. It was terrifying and completely unacceptable.
After waiting again for corrections, I noticed a strong smell of oil that has only worsened. Three weeks later, my oil levels have dropped, suggesting a leak in the pipework, and the boiler is losing pressure too.
What should have been a straightforward job turned into weeks of stress, health risks, and constant chasing. I would strongly advise anyone considering this company to look elsewhere until they improve their reliability, communication, and workmanship.
