Customer Reviews
Boiler service was quick
Booked an annual boiler service. It was pretty straightforward to arrange. The guy came, did his thing in about an hour, everything seemed fine. Not much fuss, which is good.
Reliable service, as always
This was my third time using WarmZilla, this time for a boiler repair. Just like with my previous boiler installation and the CP12 landlord certificate last year, the service was really consistent. The engineer arrived on time and fixed the issue pretty fast. It's why I keep coming back, they just get it done right.
Great combi boiler, so efficient!
I got a new combi boiler installed last month, and it's been fantastic! The installer was super quick and tidy. My hot water is consistent now, and the house feels warmer without cranking the thermostat. I'm definitely coming back for my annual service, and I've already told my neighbor about them!
Good value for a new boiler
I needed a new boiler but didn't want to overspend. I checked a few places, and WarmZilla's fixed-price quote for a system boiler installation seemed the best deal, especially with the boiler scrappage scheme. I saved about 200 pounds which was nice. The installation took most of the day, but the engineer was polite. It felt like a solid purchase without breaking the bank, which was my main concern. Happy with the overall cost.

Can you use a referral code AND a scrappage scheme discount at the same time? Trying to get the best deal possible.
Thinking of getting a new boiler from here, are the prices actually fixed? Like, no hidden extras on installation day?
Hey, how long does it typically take from getting the quote to actually having the new boiler installed? Need to plan around it.
Does anyone know if they actually do NHS discounts? My partner works for the NHS and we could really use it for a new boiler.
Anyone compared WarmZilla to Boxt or Heatable? Trying to figure out who's better for a combi boiler replacement.
