Let down by British Gas, but Warmzilla didn't disappoint!
British Gas had let me down when it came to providing a quote so I thought I'd go directly to the manufacturer for a price.
Warmzilla are the national installation partners for Worcester Bosch and their pricing was very competitive and the agent I dealt with (Kian) for the quote and survey (via a WhatsApp video call) was helpful, efficient and in no way overbearing or pushy for me to go ahead with the quote.
On the day of installation, everything went smoothly and the engineer that fitted the boiler was very tidy, friendly and professional, making sure that everything was left working as it should and made sure to answer any questions I had.
All in all, this was a first rate service and I would recommend them to friends and family and also use them again if the need arose.

I recently had an EV charger installed by Warmzilla, and the entire experience from start to finish was exceptional. Communication was top tier throughout the process—I’ve honestly never experienced such high-quality customer service and aftercare.
From the initial contact, to arranging the appointment, and through to the installation itself, everything was handled in a professional and efficient manner. The installation was first class, and the team made the whole process smooth and stress-free.
Warmzilla truly sets the standard for how this type of service should be delivered. I wouldn’t hesitate to recommend them.

Extremely Disappointed
Extremely Disappointed – Avoid if You Value Reliability and Safety
The ordering process was quick and easy, but everything after that was a nightmare. The installation was delayed by six weeks, with the engineer failing to turn up on four separate occasions. Each time I was promised a call back from customer service, but none ever came.
When the boiler was finally installed, the work was sloppy and unsafe — the chimney wasn’t fitted correctly, and the electrics were poorly done. Because of the chimney issue, smoke entered my home and made my family ill. It was terrifying and completely unacceptable.
After waiting again for corrections, I noticed a strong smell of oil that has only worsened. Three weeks later, my oil levels have dropped, suggesting a leak in the pipework, and the boiler is losing pressure too.
What should have been a straightforward job turned into weeks of stress, health risks, and constant chasing. I would strongly advise anyone considering this company to look elsewhere until they improve their reliability, communication, and workmanship.

Absolutely brilliant service from Warmzilla. My parents’ boiler broke down during Christmas week, which is about the worst timing possible, but they managed to sort everything out incredibly quickly.
From the first contact, they were responsive, professional, and really reassuring. They understood the urgency, especially with it being over the festive period, and went above and beyond to get everything up and running again with minimal disruption.
The installation was smooth, the engineers were friendly and efficient, and everything was explained clearly. It made a stressful situation so much easier for my parents.
Highly recommend Warmzilla if you need a reliable and fast boiler replacement, especially when timing really matters.
