Excellent Service from Start to Finish
The entire experience, from purchase through to installation, was seamless. The pricing and finance options were very competitive, and customer service was both friendly and efficient. The Worcester boiler we ordered has been a significant upgrade from our old Baxi. Above all, Matthew Jones, the installer, did an excellent job. He communicated clearly, was very respectful of the property, and went above and beyond to complete the work to a very high standard. I would wholeheartedly recommend Matthew and Warmzilla.

Wow — thank you for such an amazing review! 😄

We really appreciate you choosing WarmZilla and taking the time to share your experience. If you ever need anything in the future, we’re always here to help.
Will recommend to friends
I've been part of WarmZilla for a while. They've been super helpful with a couple of boiler issues. Their customer service team and engineers were polite, well informed, organised and communicated really well. The value (for the subscription and the call out if you need it) are super competitive and worth it, even for just the annual service and the odd boiler blip. Would happily recommend.

I need some help
I need some help,
On 2nd of January I ordered a new boiler from WarmZilla .
I contacted the company on 5th (the day before the installation) ti ask if there is anything needed from my end. Before that I also had provided multiple photos if the old boiler. To my surprise they said that they will postpone the installation for 8th, and that nothing else is needed from my end.
The new date and time was 8th of January between 8am and 11am. No ine arrived so I contacted the company again, and said that they will try to make by the end of the day.
Around 16pm a technician arrived, and he obviously never saw the images because he was surprised when he saw the old boiler and that he had to remove that.
After his inspection he said he can’t do the installation because the cupboard is blocking the process, and also that the pipes will need work and he doesn’t have time to do that. After that he left.
I contacted WarmZilla support, and they just said that they can’t help me until the cupboard is removed, which they knew is there from the very beginning. At the moment they refuse to refund or finish the service.
Any advice what to do?

Thank you for the recommendation; it really means a lot to us.
Great customer service.
Having no central heating or hot water with a newborn was rather distressing. I was lucky enough to communicate with Amy on the online chat bot. Although the chat bot added to my stress of trying to source a boiler as quickly as possible Amy made the experience very easy, she was extremely friendly, approachable and very knowledgable. I was able to order a boiler at around 1330 and no more than 24 hours later our boiler has been installed. Thanks again to Amy for her help, she deserves some recognition.

Horrific company to deal with
I have a monthly payment plan with WarmZilla which has been a completely unsatisfactory experience. It took ages to actually book a routine boiler service and MANY emails. Once it was serviced, the boiler was left dripping and leaking. It has been like this for 20 days and despite being reassured it was being dealt with urgently, it has still not been fixed. They simply do not care. Avoid this company at all costs. They are a scam and just want your money for no customer service.
