Customer Reviews
Good installation experience
I ordered a new combi boiler installation from WarmZilla back in October. The online quote tool was straightforward, asking all the right questions about my home setup. I went with the free smart thermostat offer, which was a nice bonus. Scheduling was easy; they gave me a few dates, and I picked one about a week out. The installer arrived on time and was very professional, laid down dust sheets and everything. He got the old boiler out and the new one in within a day, including setting up the smart thermostat. He even showed me how to use the new controls before leaving. Everything worked perfectly right after, and I haven't had any issues since. Customer support responded quickly to a question I had about the warranty via email before the installation. Overall, a smooth process from start to finish.
Easy boiler swap
Got a new system boiler from WarmZilla! The process was super quick and easy, I just answered a few questions online. The quote was fixed, no surprises. Installation happened fast too, took only a few days from ordering to getting it installed. Installer was great, really knew his stuff. Definitely shopping again for my annual service!
Decent service, minor hiccup
I had WarmZilla install a new gas boiler last month. The online quoting process was pretty good, gave me a clear price with installation included, which was helpful. The installation itself was mostly smooth; the engineer was polite and efficient. He finished the job in about 6 hours. My only small gripe was that the communication about the exact arrival window on the day of installation could have been a bit clearer. They just said 'morning' and he showed up quite late in that window, so I was waiting around a bit. But the boiler is working well, and the price was competitive compared to other quotes I got. I'd probably use them again, just wish for a tighter arrival estimate.

Thinking of getting a new boiler from here. Are their installers actually any good, or is it just random contractors?
Does anyone know if WarmZilla does those scrappage schemes for old boilers? My ancient one needs replacing and every little helps.
