Customer Reviews
Good value, minor snag
I got a new gas boiler installed. The overall price was competitive, especially with the free smart thermostat included. Installation took a full day, which was expected. The engineer was polite and tidied up well. My main criticism would be that getting a precise installation date was a bit vague initially; it took some back and forth with customer service to nail it down. Still, the boiler works great, and I feel I got good value for money.
Boiler fixed fast!
My old boiler broke down, and it was getting cold! Booked a boiler repair with WarmZilla. They came out quickly, fixed the issue with my expansion vessel, and got the heat back on in no time. So relieved. The engineer was great. Will definitely use them again for my annual service next year!
Another smooth boiler replacement
Always come back for my heating needs. This time needed a new system boiler. The process was just as easy as my combi install a few years back. Quote was clear, no hidden extras. Installers were professional. Consistent service, that's why I keep returning.
