I recently had an issue with my boiler and booked a repair through WarmZilla. From start to finish, the process was seamless. The online booking was straightforward, and I was kept updated throughout. The engineer arrived on time, was professional, and quickly diagnosed the problem. He explained everything clearly and had my heating back up and running in no time. The pricing was fair, and there were no hidden surprises. I highly recommend WarmZilla for anyone needing a fast, reliable heating repair!

A year ago, I found myself in a stressful situation when my boiler suddenly broke down in the middle of winter. I wasn’t sure whether it could be repaired or if I’d need a whole new system, but after searching online, I came across WarmZilla. The website was straightforward, and I quickly booked a boiler repair. From the start, the service was excellent. The process was seamless—I simply entered my details, and within minutes, I had a confirmed appointment. The engineer arrived on time, was polite, and quickly diagnosed the issue. He explained everything clearly and managed to get my boiler up and running again that same day. The pricing was transparent, and I appreciated that there were no hidden fees. For the rest of that winter, my heating worked perfectly, and I was really impressed with how smooth everything was. Fast forward a year, and while the repair had kept my old boiler going, I knew it was time to replace it for something more reliable and energy-efficient. Remembering my great experience with WarmZilla, I went straight to their website to get a quote for a new boiler. The process was just as easy as before. I answered a few quick questions, and within minutes, I had a selection of options tailored to my home’s needs. I placed my order, and within 48 hours, my new boiler was installed. The engineer who came out was friendly, professional, and extremely knowledgeable. He removed the old boiler, installed the new one, and made sure everything was working perfectly before he left. The difference in performance was night and day—the new boiler heats my home faster and is much more efficient, saving me money on my energy bills. Looking back, I can confidently say that WarmZilla has provided me with a fantastic experience from start to finish. Whether it was the initial repair or the new boiler installation, everything was handled with professionalism, efficiency, and great customer service. I wouldn’t hesitate to recommend them to anyone needing a boiler repair or replacement.

I recently had my boiler repaired by WarmZilla, and the experience was excellent from start to finish. The process began with their user-friendly website, where I booked a repair in minutes. Instead of filling out a long questionnaire, I uploaded pictures of my boiler, which was quick and convenient. I received a transparent quote upfront, and WarmZilla’s 48-hour repair guarantee reassured me my issue would be resolved quickly. The communication was clear and professional throughout. On the repair day, the engineer arrived promptly and was both friendly and knowledgeable. He quickly identified the problem—a faulty pump—and had the replacement part ready to go. The repair was completed in under an hour, and the engineer explained everything in detail, even providing tips to maintain my boiler. What impressed me most was how respectful he was of my home, leaving everything clean and tidy. WarmZilla followed up the next day to ensure everything was working smoothly, a thoughtful touch that showed their commitment to customer satisfaction.

I recently had a plumbing issue that needed urgent attention, and I couldn't be more impressed with how quickly WarmZilla responded. Living in London, I often expect longer wait times for services, but WarmZilla sorted the problem in double quick time. From the moment I reached out, their team was efficient, professional, and made sure everything was up and running again without delay. The whole process was seamless, and they communicated every step of the way. It's rare to find a company that offers such fast and reliable service, especially in a busy city like London. Highly recommended!

I recently used WarmZilla to replace my old boiler, and I’m beyond impressed with the entire experience. The process was completely hassle-free, from getting a quote to installation. The online platform was incredibly easy to use, and the picture survey feature made everything so much quicker than traditional surveys. What stood out the most was the speed and professionalism of the service. I was able to book my installation within 48 hours, and the engineer who came to fit the boiler was not only skilled but also friendly and efficient. WarmZilla truly feels like the future of home services. It’s clear they’ve thought of everything to make the customer experience as smooth as possible. I’d highly recommend WarmZilla to anyone looking for a reliable, modern, and affordable solution for their home heating needs. Thank you, WarmZilla, for making what is usually a stressful process so simple and seamless!

I couldn’t be happier with my experience with WarmZilla! The whole process was incredibly straightforward, and I managed to sort everything out right from my phone in no time at all. The team were absolutely brilliant, they kept me updated every step of the way, which really put my mind at ease. It’s not often you come across a service that’s this efficient and genuinely cares about keeping you in the loop.

Finally a quality service! After some bad experiences in the past, the engineer contacted me the day before to confirm and I'd already been sent a lot of information by customer services so I knew what was happening. Things didn't quite go to plan because a gas run was required, but the boys absolutely smashed it and were super cool about everything; didn't even need to run over into a second day. Was very stressed and now I'm very warm :)

I do not recommend this company. I paid them £3000 for a new boiler. They subcontracted a very young plumber who was unable to fit the new boiler properly. When I complained to them they sent me round in circles claiming that the problem is at my end, either in the hive or in the radiators. DO NOT USE THIS COMPANY. They have no engineers of their own. The new boiler is not working and is leaking water.
