Boiler installation carried out

Boiler installation carried out. Kyle the engineer called ahead of time to inform me the time he was arriving. Him and the other engineer were very friendly and efficient. Few hours and the house was nice and warm. They left the house spotless.

DISHONEST COMPANY

After more than 20 calls, over 50 email messages with thousands of photos and hundreds of What's up messages a delivery date was agreed and hours before the scheduled installation Warmzilla CANCELLED! A combination of utter incompetence and complete irresponsibility delivers disservice to the consumer. They will promise delivery without hesitation, require 100% upfront payment and at the end leave a family without hot water for a week, having signed a contract. This type of company has no place in our society. It is up to us consumers to drive dishonest and irresponsible businesses like that out of business. DO NOT USE!

They would give Cowboys a bad name!

Right where do I start, I paid to have my boiler replaced with these guys, all helpful etc at the start then the day of the installation, engineer turns up and starts work, old boiler off, I here a angle grinder going but thought nothing of it, the doors to the kitchen were closed so I waited for the cutting to stop and went in, the engineer had cut my granite splash back with out my knowledge, I was flumming at him asked the hell had he done that, the new boiler was longer than the old one he said so he cut my splash back to make it fit, I said why didn't to board it out so it missed the splash back, and there is water pissing out of my ceiling, he's melted a plumbing fitting, no response from the idiot, but I then had to go to a hospital appointment so I had to leave him working, by the time I got back he was gone, my splash back is ruined, I found a hole in my ceiling and a massive water stain, I couldn't believe it, I had a leaking radiator, the boiler it's self is out of level on the wall, the pipe work underneath is not level, the electric cables were poorly done, he told my partner we can't use the heating only hot water as he couldn't get it to work, I go outside and he's left all his rubbish laying about, I look up and the flue is leaning to one side, he's also snapped off a toilet overflow and I'm guessing he used a hammer as he took a chunk out of the face of my brickwork, I was so pissed off, I contacted warmzilla, they were not much help, so I didn't feel safe using the boiler and thank god I didn't, I got gas safe put, they came about a week later, he checked everything that's to do with safety but not workmanship, he found a few issues they needed to put right, one thing was they never connected the condense pipe back up to the waist pipe under the sink so if I ran the boiler it would of leaked, warmzilla said everything would be sorted out, another engineer came out and put the gas safe issues right, I then wait for the company to say what they are going to do about fixing my damaged granite splash back, the hole in my ceiling, the massive water stain, straighten up boiler, pipes etc, fix the brickwork, I got a email a few days later offering me £50 for having to get rid of all the rubbish and £150 as a good will gesture, that doest even come close to the cost to repair the damage and put things right, I say no to there offer, I hear nothing, they then send me a email asking if I want to join thier warranty club a monthly fee, I reply and ask are you taking the P but a bit stronger words than that, I get a response that bad words will not be tolerated, we'll I'm now going to war with this cowboy company, I paid with a credit card so they are on the case, been told to speak to CA who should put me in contact with trading standards, then after that I'm taking them to the small claims court, I was a tradesperson, I was a stone mason, I then went on my own and fitted kitchens, bathrooms, small extensions, landscape gardening, I do have a eye for detail and would never do work to the low standard of WarmZilla,I just couldn't do it, Warmzilla you should be ashamed of your workmanship!.

Shocking service

Shocking service, took months to book in my boiler getting serviced even though I pay a monthly sub subscript.

The person came round, did it within five minutes then came back because they forgot something. It can be more rushed if they tried.

And apart from bang and crashing around my house, you left everything switched off so the Water when I get through to the radiators

Extremely suboptimal would not recommend from now on. I’ll get my own person to come and service the boiler.

My experience has been incredibly poor…

My experience has been incredibly poor unfortunately with Warmzilla. They book the service, then I wait the whole day and nobody turns up. They don’t even care to inform me. Then I have to chase to them for 3 weeks to get this sorted and still nothing. I personally don’t think they care as they have enough customers now. Personally I will say, avoid them.

Update: Following my review, Amy helped arrange the cancellation and refund, which I have now received. I appreciate her personal efforts. Without her help, I could have spent months chasing the refund. My original review still reflects my experience. I came to WarmZilla for a service, so the overall experience remains disappointing despite the refund.

Very poor service

This was the quickest service I've ever had. The central heating system wasn't even run at all which has always happened in the past.
On top of that I was told I'd be emailed a copy of the service for my own records which I still haven't received. I contacted Warmzilla to chase this up but that request seems to have been ignored as well.
