“We’ve just had a new air conditioning system installed by WarmZilla at our London property and the experience was excellent from start to finish. The team were friendly, professional and clearly very knowledgeable. Everything was explained clearly, the installation was neat and tidy, and the system works perfectly. One unexpected benefit has been how much quieter the home feels. Being able to keep the windows closed has made a big difference with outside noise, which is a real plus in London. Overall, we’re extremely happy with the installation and wouldn’t hesitate to recommend WarmZilla to anyone considering air conditioning.”

“I have a monthly payment plan with WarmZilla and the experience has been completely unsatisfactory. It took an excessive amount of time and numerous emails just to arrange a routine boiler service. After the service was finally completed, the boiler was left dripping and leaking. It has now been 20 days and despite repeated reassurance that the issue was being treated as urgent, it remains unresolved. There has been no meaningful communication or action. This company shows no regard for customer care. I would strongly advise avoiding them altogether. They take your money and provide little to no service in return.”

“I recently had a new boiler installed by WarmZilla and the whole process was exceptional. From the moment I made the enquiry to final setup, communication was clear and every step was handled with care. The booking was easy, the quote transparent, and the engineering team turned up on time. The installer was polite, tidy and very knowledgeable — they explained how everything works, tested the system thoroughly, and left the site clean. Best of all, there were no nasty surprises with hidden costs. The boiler’s performance has been great, and WarmZilla’s customer service didn’t stop after the install — both follow‑up and after‑care were impressive. Would highly recommend WarmZilla for anyone seeking a warranty backed, reliable boiler installation with excellent service throughout.”

“Thank you for my new EV charger!”

“I had my EV charger supplied and fitted by WarmZilla, and the whole experience was first-class from start to finish. The ordering process was simple, the communication was clear, and the installation team arrived right on time. Everything was fitted neatly and professionally, with zero hassle. The charger itself is excellent — fast, reliable, and easy to use. The app makes it simple to schedule charging at cheaper off-peak times, and I love being able to track usage and costs. It looks sleek on the wall, and I can tell it’s built to last. WarmZilla took all the stress out of getting set up. They handled everything smoothly, and I now have the confidence that my EV will always be ready to go. I’d highly recommend WarmZilla to anyone looking for a top-quality EV charger with service that goes above and beyond.”

“Got recommended WarmZilla and I'm so glad I went with them. Getting a quote was so quick and easy and gave me the option to pay on finance (interest free!) which is a huge relief as getting a boiler can be costly. Shoutout to Josh and Caryl for making sure I was informed every step of the way to dates of the installation, what time the engineer would arrive, and even going beyond to call after it called installed to check if I had any further questions. All in all, very happy with the service provided from WarmZilla and will recommend them to anyone”

“This was the best and easiest boiler installation ever. Survey took away the uncertainty of buying a boiler. And I could spread the cost over 2 years without interest was just what I needed! And the customer support was amazing, between Josh and Caryl, they both always made sure to keep me informed, the communication was empathetic and clear. A great experience and one I'd happily do again.”
