Absolutely brilliant service from start to finish! I ordered a new boiler on Friday and it was installed just three days later. The installation took a little over two hours and was completed perfectly with no issues at all. Any enquiries I had before and after purchasing were answered straight away, which was really reassuring. Fast, professional, and hassle-free - I couldn't be happier and would highly recommend them!

Excellent Service
Excellent communication from WarmZilla throughout the process. First class installation by Warmserve. The two installation engineers were absolutely excellent. They were courteous, friendly and helpful. Problems were dealt with constructively and in a no-fuss manner. A professional installation. Recommended.

Excellent experience
A new boiler was installed in a rental flat yesterday. We had a problem in not being able to find the stockcock but the engineer managed to find a solution, which was excellent.

Insurance doesn't work.
I took out boiler cover in March 2025.
The annual inspection was carried out in the summer, but when I started using the central heating in October I noticed the pressure gauge was always in the red zone.
Despite an extensive email exchange more than 35 - well attended by Amy- the comapny was unable to arrange anyone to come and see what the problem was.
As a resuult I cancelled the cover.

Hi Rob,
Thank you for taking the time to share your experience.
We’re sorry to hear about the frustration you encountered after taking out boiler cover with us. While we’re pleased that the annual inspection was completed, we regret that we were unable to arrange a follow-up visit when you later identified an issue with the pressure gauge. We appreciate you highlighting the efforts Amy made to assist via email, but we understand that this did not resolve the problem. This is not the level of service we aim to provide, and we’re sorry that this led you to cancel your cover.
Your feedback has been noted and will be used to help us improve our processes going forward.

Very poor service
Took nearly 7 weeks before I could get my boiler serviced. I had to call the plumber twice before service was completed. Two days latter it developed a leak. Now it's taken 2 days to get someone the fix it. I am still waiting.

Conversion from to combi
Warmzilla installed a new combi boiler for me, replacing an old hot water tank system in a fairly complex setup. The work was carried out professionally and to a high standard. Throughout the process, the Warmzilla support team were proactive, polite, and clearly very knowledgeable. They took the time to understand my specific technical situation and communicated clearly at every step. Overall, a very professional experience and I would happily recommend them.

Hi,

It’s great to know that both the installation work and the support from our team met a high standard, and that our communication and technical understanding helped make the process clear and smooth for you.
Your recommendation means a lot to us, and we truly appreciate you choosing Warmzilla.
Nice job carried out by Warmzilla and team
Customer rep that i chatted with was helpful in getting a competitive price and arranging a lot quick. any changes, i was informed on time and in one occasion, i was compensated for the delay. All through the team was helpful and the installer tried his best to get the boiler working. The only sad part was that the installer used my cleaning products and equipment without my knowledge and this is absolutely wrong.
