Had to chase the for our annual boiler service
Had to chase the for our annual boiler service. They do not automatically remind you or book in advance. When I rang to arrange service the engineer came out and condemned the boiler as unsafe. The time between my annual service date and me chasing them to arrange we were living with a dangerous boiler. When the engineer cut the boiler off he said WarmZilla would be in touch to discuss a replacement, they never did so I went to BoxT (very good service).
I would not recommend WarmZilla.

Hi Gary,
Thank you for your feedback. We’re very sorry to hear about your experience and the concerns you’ve raised.
We understand how worrying it must have been to discover your boiler was unsafe, and we sincerely apologise that you felt you had to chase for your annual service and did not receive follow-up contact after the boiler was condemned. This is not the level of service we aim to provide, and we appreciate you bringing this to our attention.
Your comments regarding service reminders and the lack of follow-up have been noted, as this is something we take very seriously and will review internally.
Thank you again for sharing your experience — feedback like this helps us identify where we need to improve.
Excellent service
Warmzilla`s website gave me a good choice of boilers and made it easy to pick one. After I picked one, I sent pictures over and no costs were added on. Engineer came out and fitted on the chosen day no hassles. Excellent job done. Very happy. Would recommend.

Boiler service good, everything else was poor
Where the service of the boiler was top notch, having to be at least 2 months from boiler should have been done was disappointing part of the process. Having to keep getting in touch to see when the boiler was going to be serviced was not good.

Hi John,
Thank you for your feedback.
We’re really pleased to hear that the boiler service itself was top notch, but we’re very sorry to hear about the delays and the need to chase for updates.
Waiting that long for a service and having to follow up multiple times is not the experience we want for our customers, and we completely understand your frustration. Your comments are really important and will be shared with the team to help improve our scheduling and communication.
Thank you again for bringing this to our attention, and we appreciate your patience.
ZERO communication
ZERO communication.
Spent a grand getting an EV charger installation booked. They allowed me to book a good date.
As soon as they had my money they went quiet. Ended up having to speak to their live chat nearly every day. Excuses about suppliers letting them down, but they made no attempt to update me. On day of delivery, they say their supplier tried to deliver but nobody replied. I was here all day and nothing showing on ring doorbell.
Excuse after excuse and no communication. Even after raising a written complaint I was ignored.

Terrible service
I have home care boiler cover with Warmzilla. They have been awful. I have had a problem with my boiler for over 6 weeks now and it’s still not fixed.
It takes days for the company to reply to my emergency breakdown requests and then days more to get an engineer out. I waited 2 wees for 1 engineer.
In the mean time I’m paying a fortune in bills because my boiler won’t turn the heating off!
I’ve finally had an engineer identify the problem but have been waiting a week to hear from Warmzilla about getting the problem fixed now we know what the problem is.
Terrible service. Won’t be renewing my contract

Simple
Simple, efficient process from start to finish. Placed the order online, submitted photos of my property & boiler was fitted 4 days later. I was kept informed at all stages. The fitter turned up on time, did a good job, tidied up & took away the old boiler & all other rubbish from the job. Would highly recommend WarmZilla.

Extremely Poor Radiator Installation and Stressful Aftercare Experience with WarmZilla
I am extremely disappointed with the radiator installation carried out by WarmZilla in my living room. The quality of the work was far below what any homeowner would reasonably expect from a professional heating company.
The installation was left in a very poor and unfinished condition. The pipework was exposed and poorly aligned, the wall around the radiator was left damaged, and the overall finish looked careless and unprofessional. Instead of a clean installation that blends into the room, it looked as though the work had been abandoned halfway through, making the radiator area look messy and poorly executed. Seeing this every day in the main living space of my home was extremely upsetting.
What made the experience even worse was the long and stressful process of trying to get WarmZilla to resolve the issue. I spent over one and a half months raising complaints and communicating with them repeatedly. Despite the significant amount of time, emails, and effort involved, the problem was never properly resolved. Throughout this period, I felt there was no genuine intention to correct the poor workmanship.
In the end, I had no option but to hire an independent professional heating engineer to correct the installation. The engineer had to reinstall the radiator to a proper professional standard and repair the damage left behind. He also managed to hide the pipework and leave the installation looking neat and properly finished.
This resulted in significant additional costs that I should never have had to pay, as well as a prolonged period of stress dealing with the situation.
This experience caused unnecessary financial loss and a great deal of stress, negatively affecting my daily life. Based on my experience, I strongly recommend that others think very carefully before using this company. The installation left in my home and the lack of resolution afterwards were extremely disappointing.

We're really sorry about this situation. I can see that the team has sent you proof that we were trying to contact you to do whatever was necessary regarding the work but those emails were missed by yourself.
We regret that we weren't able to come to an agreement but thank you and wish you all the best :)
