Unsafe Installation, Extra Charges & Ongoing Issues – Now Pursuing Section 75
I am extremely disappointed with my experience with WarmZilla.
From the beginning, the process was poorly handled. My installation was originally scheduled for 12 December 2025, but delays and confusion meant I had to take unnecessary time off work.
The engineer who contacted me beforehand did not appear fully aware of the job, which immediately raised concerns.
On the day of installation, I was asked to pay an additional £150 for an electrician to install a fused spur in the loft, as the installer said they could not complete this themselves.
I paid this, however:
No electrician ever attended
No Minor Works electrical certificate was provided
This is completely unacceptable.
The installation itself has been carried out to a poor and concerning standard:
The flue appears incorrectly installed and visibly protrudes
It drips water when the heating is on
After contacting Worcester Bosch, I was advised (based on photos) that the flue does not appear to meet manufacturer guidelines
This raises serious safety concerns, which should never happen with a new boiler installation.
Overall, I have been left out of pocket, with unresolved issues and a system I do not feel confident using safely. The experience has been stressful and time-consuming to try and resolve.
As a result, I am now pursuing a Section 75 claim with my finance provider due to breach of contract and the standard of work carried out.
If you have used finance or a credit card for a WarmZilla installation and are experiencing similar issues, I would strongly recommend looking into your Section 75 rights, as you may be able to recover your money through your lender.
I would strongly advise others to think carefully before using WarmZilla. A boiler installation should be safe, compliant, and completed properly the first time—not leave customers dealing with ongoing risks and disputes.

Hi,
Thank you for your feedback.
We’re genuinely sorry to hear that you feel disappointed with your experience, and we take all concerns raised by our customers very seriously.
Firstly, with regard to scheduling, the period leading up to Christmas is one of the busiest times of year across the heating industry. While delays can occasionally occur, we do always aim to communicate clearly and minimise disruption, and we apologise for any inconvenience caused in your case.
In relation to the electrical work, installing fused spurs or carrying out electrical modifications is not included within a standard boiler installation. This is clearly outlined within our terms and conditions agreed at the point of purchase. Despite this, we arranged for this work to be completed for you at a significantly reduced cost as a gesture of support, which we feel is important context.
We are concerned by the statements made regarding the safety and quality of the installation. Assessing an installation solely from photographs, without a full on-site inspection, can lead to inaccurate conclusions. At this stage, no issues have been formally substantiated through the appropriate inspection process.
WarmZilla has an excellent track record of installations carried out safely and compliantly across the UK, and we are fully committed to resolving any genuine, substantiated concerns. If there are outstanding issues, we would welcome the opportunity to investigate them properly and put things right where necessary.
We are here to help and remain open to working with you to reach a resolution. We kindly ask that you reconsider the statements made in your review, as they do not reflect the full context of the situation.

Used to be good, now completely unreliable. Do not recommend.
I have used this company before and even recommended them to friends, but I deeply regret it now. Their service standards have dropped significantly.
The booking process for my recent service was a mess with constant delays. More importantly, they have failed to provide the required service reports—not only for this year but also for last year, despite my multiple follow-up requests.
A company that ignores a loyal customer’s repeated inquiries and fails to provide essential documentation is not worth your money.

A company that gets customer service
A company that gets customer service. If only all companies were like Warmzilla. Just made my second major purchase with them of air con having bought a boiler off them before. I also have a boiler cover policy with them. Their prices cannot be beaten - lowest to be found but they operate a price match in the unlikely event that you find a better price - and their customer service is phenomenal. Nothing is too much for them. They respond quickly and professionally to any query you raise. They really are my go to company for the household items they offer and they should be yours too!

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.
