Needed a new boiler soon as, as mine was done and l had no hot water or heating. WarmZilla got me sorted within 24 hours as promised. Everything arrived when they said it would including the engineer. Glad to have heating and hot water back, all l have to do now is work out how to set it properly to my needs.

Great fitting but annual boiler servicing is nightmare
Warmzila were great when they fitted my new boiler. The problem I am having with them is that I took a boiler service and maintaience contract with them over £170 per year but trying to get them to sort out my annual service is a nightmare. I have requested my service several times now but keep getting fobbed off saying they cannot get a engineer in my area to carry out the service. So buyer beware they talk a good game but cannot fulfill their side of the contract.

Hi,
Thank you for your honest feedback. First of all, we’re really pleased to hear that you were happy with the boiler installation itself — that means a lot to us.
However, we’re very sorry to read about the difficulties you’ve experienced arranging your annual service. We completely understand how frustrating this must feel, especially when you have a maintenance contract in place and expect it to be straightforward. That’s absolutely a fair expectation.
We would really like the opportunity to resolve this properly for you.
We’ll escalate this with our service team as a priority and ensure this is addressed as quickly as possible.
Thank you again for bringing this to our attention — we genuinely value your feedback and the chance to put things right.

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!

We’re really pleased to hear that the engineer was able to clean out the grit from the compressor unit and explain the manual versus auto settings clearly. It’s great to know this has given you better control over your heating. We’ll be sure to pass your kind words on to the engineer.
Thank you for taking the time to leave a review — it’s much appreciated.
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.

We’re pleased to hear that, despite the initial difficulty locating the stopcock, our engineer was able to find an effective solution and complete the installation successfully. We always aim to overcome any challenges efficiently and with minimal disruption, so it’s great to know this was reflected in your experience.
Thank you for choosing us.
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.
