Our second boiler purchase and…
Our second boiler purchase and installation from Warmzilla. Overall an easy pleasant experience. Sales team and engineers were really helpful. We have a maintenance contract with Warmzilla as well and when Craig the installation engineer fitted the boiler he also sorted out a problem we had with the zone value. All in all really pleased. First class service.

Not a Smooth Process, But They Put Things Right
My wife and I had been planning to install air conditioning at our home for a while, so I spent some time researching companies in West Yorkshire.
I looked at a few but decided to go with Warmzilla because the whole process was really simple. Getting a quote was easy, I answered a few questions about what I needed, was given three options to choose from, and the price was fixed for the installation. After choosing the units I wanted, I could book an installation date and choose a payment option. Everything up to that point was quick, easy and a very good experience.
The road started getting a bit bumpy after I booked the installation. My original Thursday appointment had to be changed because of a delay with the delivery, so I moved it to a Saturday. So I lost one day of my Hollidays I was booked for Thursday install
I also wanted the pipework chased into the walls for a cleaner finish. Warmzilla told me they do not carry out surveys and that the installers work from the photos customers upload. I wanted to speak to someone about this, so I requested a call. They rang me the next working day and agreed that the installer would contact me. That did not happen until I chased it up myself, and I later found out the engineer had been on holiday. We ended up having a video call instead and he confirmed where I should chase the walls.
I then took another day off work to prepare everything before the installation. On the Friday evening I received an email saying the electrician was off sick, but the air conditioning engineer would still come and finish most of the work. The next morning I got a text from the engineer saying he was off sick too. That was probably the most frustrating part of the whole experience.
My house was covered in dust sheets, from wall chases and left for ac installation, as its lived house
On Sunday I received a email from Rhys, the Installation Director, who apologised and promised to get everything sorted.
On Monday I received call from Warmzilla and they try to push install for nearly 1 month, which I not agreed and asked call from more senior staff, I have call back from same guy who's emailed me on Sunday, and after explaining my situation, including the fact that my house was covered in dust sheets because I had already chased the walls, Rhys really stepped in and did everything he could to help. He arranged another contractor to come the following Monday and they completed both the air conditioning installation and the electrical work. Rhys also kindly offered a free service next year to make up for all the hassle, which I really appreciated.
The other issue was having to chase the paperwork, which took about four weeks.
Overall it was a stressful few weeks and communication could definitely be better. It would also help if customers had dedicated person looking after their installation, instead I don't know who's responsible for that install, luckily like mentioned I have email from Rhys and I able to ask question directly to him
In the end, though, everything works perfectly and I am happy with the finished installation. Despite the problems, I would probably still choose Warmzilla again because when things went wrong they did make the effort to put them right. I hope they take this feedback on board because there is definitely room for improvement, especially with communication and keeping customers updated.

Average
We went with Warmzilla in December for our boiler service. Have left 2 previous 1 star reviews which they asked us to remove while they sorted issues. First boiler service and they did not even take the front off the boiler so not convinced it was serviced. Arranged for someone else to come out who did not turn up. Finally got the service done. Then had an issue with our boiler and it took 3 months for them to send someone out. We had a new boiler installed last week and can’t fault the guy who did it. Would give 5 stars for him and the boiler fitting. Not sure I believe all the positive reviews as they ask people to remove negative reviews while they sort out the issues. Not sure if we will renew in December based on our overall experience. This is an honest review base on our overall experience. If you get a good tradesman to come out it’s fine but not all are good and the timescales are not great. Yes we had heating and hot water so not expecting same day or next day check but three months is far to long to wait for a boiler check when you report an issue, they are cheap and if you get the right tradesman it’s worth the money but there are issues and delays

Questionable business practices
Update: A lot of proactive comms from WarmZilla after this review - I has to chase everything before that! I have since been contacted by WarmZilla with a legal-style letter threatening action if I do not remove my review. I was then offered £50 as a goodwill payment in return for taking it down. Despite this, the website still shows new customers being offered installation dates such as 3 September, whereas the earliest date I was given for my order (placed on 3 July) was October 2026, communicated to me by email. Just building a winter order book.
———
Our AC order was taken with a confirmed installation date. We were told the installation would happen quickly, but after a month of confusing WhatsApp messages, we were only then informed of major delays. The deposit was also requested before any confirmed installation date could be given, which felt unreasonable and unprofessional.
The whole experience has been frustrating and has not felt transparent. If supply issues were already a problem, that should have been made clear at the outset instead of leaving customers in the dark. I would strongly advise others to be cautious before placing an order.

They went the extra mile
We got air con across two bedrooms and our living room. There were a few bumps along the way with scheduling and pipe routing, but WarmZilla really bent over backwards to get it right, listening properly when we had questions and adjusting the plan until we were happy. End result is genuinely great, quiet, does exactly what we needed, and the engineers left everything spotless. They clearly cared about getting the outcome right, not just finishing the job. Would recommend without hesitation.

Proactive resolution, efficient order process in testing conditions
Although I have had an interesting encounter with WarmZilla, they have taken the feedback seriously and I have had a few conversations with Rhys who has been very proactive and upfront. Although the installation didn't happen today, they've tried to work with me and find a date within the next 14 days. As we are going overseas for an extended period of time, we may not opt to go with this date but the post experience follow-up has been positive and we may end up going with WarmZilla as a result of this,

Not reliable anymore
I’ve had a plan with WarmZilla since November 2023. For the first two years, everything worked smoothly: quick responses, friendly service, and easy bookings. Unfortunately, the last 12 months have been a very different experience.
It has become almost impossible to book anything. You have to chase them constantly, and communication feels slow and fragmented. I requested a boiler service on 9 June — it’s now 6 July and it still hasn’t been booked.
Earlier this year, in January, I had an issue that took more than two weeks and around twenty emails before someone finally came out to look at it. The fact that there is no customer service phone number makes the whole process even more complicated.
WarmZilla used to be reliable, but sadly the service has declined significantly.

Postponed but decent customer service
We booked an installation for AC with Warmzilla and 3 days before the installation date they postponed the installation because of nationwide stock issues.
Initially unhappy as this AC is very important for my health issues and also barely any notice given of the postponement. However, they did everything in their power to source a unit and I have a new installation date for next week which is only a week later than planned.
Decent customer service during a time of difficulty with stock issues.

So i recently had Air Conditioning installed, or if the government's watching, it identifies as an Air-to-Air heat pump. From start to finish, Warmzilla kept me informed of any delays, which, when it's 30 degrees outside, is expected. The engineers who fitted the system did a great job with very little obstruction to my day-to-day work, and in all. Fantastic job, would highly recommend Warmzilla to anyone looking for Air Conditioning , so its 5 stars from me,

Don’t bother
Update following response:
WarmZilla. I’m sorry you are confused by my comments. Your response to my review here is clear and concise - had I had this level of honesty and transparency from your customer support service I would have been able to manage my expectations. Somethings clearly got lost in translation from you being able to set out the below and how your agents curate their narrative through the WhatsApp service
Originally review
Don’t bother. Filled out survey online and used their what’s app service as directed by the website. They take ages and I mean two days on average to get back to you. Gave them all the info they asked for, in every response they say how busy they are, fine I don’t mind, I was just looking for some quotes annmd install dates. Jump through all the hoops then get a final message to say ‘it’s a big install, come back in Aug for prices and dates’…oh so you don’t want to even entertain taking my money then. Fine I’ll go with a local independent installer who know how to treat customers

Excellent Service Despite a Challenging Installation ⭐⭐⭐⭐⭐
Here’s a polished Trustpilot review that sounds natural and detailed:
I had an excellent experience with Mozilla from start to finish and wouldn’t hesitate to recommend them.
I live on the 14th floor of a high-rise block, and my boiler flue is located on the outside of the building, which makes it difficult to access. Because of this, I’d previously contacted three other companies. They initially said the work would be possible, but after attending they changed their minds, or tried to charge extortionate prices for scaffolding and other access equipment without properly exploring alternative solutions.
Mozilla were completely different. The colleague I spoke to took the time to listen to all the details of my specific situation and understood the challenges straight away. Rather than dismissing the job or immediately suggesting expensive access methods, they explained that there was another approach they could take. They were knowledgeable, helpful, and gave me confidence that they knew what they were doing. They also got everything booked in quickly and kept me informed throughout.
On the day, the engineer arrived on time, was very friendly and professional, and explained everything to me in great detail before carrying out the work. He completed the job in around half a day despite the complications with access, and everything was left clean and tidy afterwards.
I’m extremely happy with the service I received. It’s refreshing to find a company that takes the time to understand a customer’s situation instead of looking for ways to overcharge. If anyone asked me for a boiler company, Mozilla would definitely be my first recommendation.
