WarmZilla Avis 1 993

They turned up on time were polite courteous and professional very careful around the areas that they were working very good installation minimum fast minimum mass very polite would use again

Engineer, Kevin McGlynn, turned up exactly when scheduled and was extremely helpful and friendly. Old boiler removed and new one fitted in a very short period of time, and with an extremely high standard of workmanship. New system and controls fully explained, and all waste removed and tidied up.
Would highly recommended WarmZilla, and Kevin, for their efficiency and standards of workmanship.

I've requested a Warmzilla quote after local plumbers were giving me quotes for a new boiler at way higher prices. Paul was sent out to my property in Aberdeen, and he was really professional and friendly. He was done with the whole thing in a day.

I can't speak of the aftercare, but so far my experience with this company has been excellent.

🔥 Shoutout to WarmZilla! 🔥
I recently purchased a boiler from WarmZilla, and I couldn’t be happier with their service. From start to finish, everything was smooth and professional. They offered a Blue Light Card and Emergency Worker discount, which was a great bonus. The team arrived exactly on time, completed the installation within the promised timeframe and provided excellent advice throughout the process.
Their 0% finance option made the purchase even more convenient, and the entire experience felt hassle-free. WarmZilla truly delivers on their promises brilliant service, reliable, and customer focused. I highly recommend them to anyone looking for a new boiler! WarmZilla is the way to go! 💯

Turned up on time and did a great job fitting it in a very quick time. Clean job, nothing left, no mess, explained everything on how to operate and great value for money. Now have hot water on demand instead of an inefficient boiler and tank.

We had a new boiler fitted over a year ago with warmzila and they did a brilliant job cannot fault them I took out my boiler cover with them also so thank you to all

Work men were on time seemed nice & I felt contented to trust them & leave them alone

Joined WZ just under 9 months. I decided to contact them about my boiler service which is included in my package. Considering I contact the 2 months ago about this via WhatsApp email and online chat. There incompetence exceeds their service.
Still waiting for a reply: after being told on the last two contact occasions that they will get back to me
...WHEN???

However, someone did text me at 23.30 one evening asking if I'd be in the next day.. I responded the next day to say I would, they responded saying they had already passed by...who texts at 23.30 from a reputable gas service company.??? to ask such info from a customer.

They didn't even answered my most important question as to what company they were from. Only that they were asked by WM to do a service.

I checked with WZ and NOT even they know who this dickens this person is..what the hell!

Now waiting AGAIN for WM to reply and sort out who will be attending my boiler service.

Pathetic!

So sorry I joined WZ.

Professional great service, contacted before arriving and arrived on time.

Excellent, efficient and reliable

WarmZilla’s customer service is, I would say one of the best. Whether email or phone or via whatsapp, they respond quickly and give you quality customer service. They are friendly, professional, and knowledgeable. They check in with you before and after and are not pushy when it comes to selling. They sent out a good engineer who knew what he was doing, and with good experience. Im really glad I went with them, and I wouldn’t hesitate to use them again (hopefully I wont have to with a new boiler now haha).

Purchased a boiler and went through finance. Waited nearly two weeks then one working day before installation I was told they don't cover my country.

They could've easily told me this at the start

Spot on time
Engineer Steve brilliant 👏
Can't fault nothing

Arrangement of new boiler was prompt with good communication from WarmZilla throughout. Boiler engineer chosen was to a high standard with everything sorted out and explained in good time.
Follow up call after the installation was good with any question properly answered.
A pleasure to work with from start to finish.

Consistency reliable and competent

The service was really good. The man that installed ( lee ) was very informative, clean and tidy and very knowledgeable

**UPDATE: We have managed to have a visit by an engineer (arranged within days) to connect up Opentherm and it is all working well. Considering this and the previous issue where the sub-contractor didn't do the job to my expectations, and the fact that the sub-contractor misled myself and the Warmzilla customer service - I will keep the rating at 3 stars. I do have faith that Warmzilla will improve on their Opentherm installations and hopefully sub-contractors tarnishing their reputation will not be used again. The only thing that I am waiting for is the boiler warranty documents - I hope to receive them soon. **

**EDIT: Rhys is looking to get this rectified and the errors are being rectified. Rhys's response is really encouraging and they seem really keen to fix the issues. I have revised the star rating since. The issues of the customer service knowledge has been refreshed, so this shouldn't happen again. **

I ordered a Veissmann 100W Combi to take advantage of the 12 year warranty along with the great reviews. I have my own smart controls that are Opentherm compatible (previous boiler wired up for opentherm), so I selected reconnect the thermostat in the ordering process.
Warmzilla were initially very helpful and proactive. Although the installation date had to be moved, it wasn't too big of an issue for me.

On installation day, a third party contractor showed up and I explained at the time that I want to retain Opentherm connections to the boiler.

At the end of the install, the engineer was packing up and didn't mention the connections until I asked if Opentherm was operating. He responded that he couldn't do it, and to my surprise didn't even know what open therm does. He made up some story about a special connection, but it turns out they just needed a £1 cable to connect it all up to the two terminals on the thermostat and the boiler. The engineer left, with the boiler in on/off configuration.

I noticed that the engineer had thrown a load of rubbish to obscure areas of the attic space and failed to reconnect the loft ladder. There was also a scattering of suitcase thrown across the place - the least of my issues.

I reported the issue to Warmzilla, but the response has been so slow. It had taken a week to contact the installer to only receive some made up story that the thermostat is not opentherm compatible from the installer- despite being connected to it before. I've also received false information from Warmzilla about veissmann claiming that the maximum efficiency of the boiler can be achieved in on/off configuration - Just google 'Veissmann Opentherm' and they have a web page devoted to the benefits in increased efficiency.

I am now getting frustrated that the company is not offering a solution to the issue. It's an easy fix, probably 20 minutes work with a £1 cable.

So far, I have rejected to release the interest free finance to Warmzilla and will continue to do so until this is resolved and the 12 year boiler warranty is registered.

They need to improve their customer service response time and test their installers. iheat, heatable etc has plenty of information about opentherm and the benefits, I am regretting my decision to go with warmzilla. The one star is down to both the installer and warmzilla trying to mislead me on the benefits of opentherm and poor communications after installation.

Caused more issues than help - the only reason they get 2 stars is because of their customer service response times (shout out to Josh for his persistence)

- Their contractor arrived much later than estimated on the day, with no updates
- Their contractor caused our wiring to smoke and continued to do so despite tripping the electrics several times, we were later told by a serviceman sent by the boiler manufacturer that we were lucky a house fire did not occur
- Their contractor failed to come prepared with basic materials, using our own cement instead
- This first installation left us without heating and a broken boiler despite being brand new. It was left non-functional for eight days as a result of their contractor frying the circuit board of a brand new boiler
- Two repair appointments were arranged by Warmzilla in between the first failed installation and the fix, one where no one turned up so we were left waiting, and another that was cancelled less than 24 hours before.
- Warmzilla claimed we had to take it up with the manufacturer directly as it was under warranty. When the manufacturer sent someone to look, they showed us the fried circuit board (thanks to Warmzilla's contractor) which meant the boiler was not faulty.
- It has taken almost 7 weeks to receive the gas safety certificate and warranty, supposedly a timeline outside of their control

Warmzilla eventually repaired the boiler and after some negotiation received compensation in the form of 11% of the price we paid, but it was so much hassle, back and forth, re-arranging plans/working arrangements after Warmzilla did not stick to their appointment dates.

The only reason there are stars in this review is because the customer service was quick albeit painful and stand-offish at times.

Great service, fast, timely
Great follow up support

Excellent service from getting the quote to fitting .
