Our heating system (installed 37 years ago) had died. We looked on Which Trusted Traders website for a local company and HeatGlow were exemplary. The initial survey by Gareth showed what needed to be replaced (i.e. everything apart from the radiators and pipework which they were able to save with some TLC and a flush through). They turned up as promised and installed a new Worcester Bosch boiler, replaced the hot-water cylinder and installed a header tank plus the flush through in 4 days and charged exactly as per their quotation. All of their people were very polite, considerate and tidied up afterwards. Strongly recommended.

Returned from holiday on a Friday to find our 14-year-old gas boiler in its death throes. By Sunday it was no more! Contact via email that night and they managed to fit us in due to a cancelled appointment the next day. Very thorough in the diagnosis of the problem (broken valve). Part ordered and fitted 48 hours later. The boiler is back to full function and with a new PCB board and electrodes 2 years ago should run for a while yet. Hopefully! Very happy with the service and professionalism. No mess or damage to the surrounding kitchen, unlike the previous gas-fitter. I will be returning to them for my gas and plumbing needs.

Contacted the firm Monday afternoon. Jack arrived the following morning at agreed time. The issue was the pressure in the boiler which was erratic and various issues had to be ruled out. Also it’d been leaking water which Welsh Water weren’t too happy about. Jack was helpful in that score as well checking throughout the house for leaks and stabilising the boiler. This is a small but customer focussed company with a great ethos. Thank you folks.

I usually have my boiler serviced by the company who installed it (back in 2007). However, due to Covid, they were unavailable and so, I looked up Trusted Traders reviews. It was so easy to book an appointment online (which was within a few days) and received several communications with confirmation and updates as to the appointment. They arrived on time, were polite, took off their shoes ( wasn’t necessary, but noted and appreciated). I informed them of ongoing issues (losing pressure frequently and a little leak from bathroom towel radiator). No leak since and pressure issue is looking good. Thank you Heatglow - you’ve got it nailed in my view!!! It’s left me with conflicting feelings. I still trust the original company, but I am impressed and very happy with Heatglow’s service from beginning to end..... whilst I don’t have a ‘relationship’ with them (I know them/they know me type of thing), I am converted!!

I found HeatGlow on the Which trusted traders site. Booked a boiler service via their web site - it was very straightforward and I was able to book a time and date for the visit. The price was even less than what I had paid 3 years previously with another firm. From then on I received both emails and messages with my invoice and confirmation of date/time including the name of 5he engineer carrying out the work. Everything completed on time and certificate issued electronically. Every aspect of dealing with HeatGlow was excellent and I would certainly use and recommend to everyone.

Heatglow installed a new Worcester Bosch boiler, replaced two radiators and fitted a new electric shower in one day as promised. They gave me good advice when then visited to quote for the work and provided a competitive price. They were helpful, friendly and easy to deal with. I will definitely use them again.

The guys responded to an urgent request promptly and scheduled in the work whilst agreeing to honour a much earlier quote. On the day, they worked professionally, demonstrating excellent social distancing disciplines. They communicated well throughout. Given that carpets and floorboards were lifted you would not have noticed if you hadn't seen it due to their commitment to putting everything back in its place and cleaning up after themselves. The new boiler was fitted with the minimum of fuss despite having to work around the challenges of an old house. We will certainly use their services again and have no hesitation in recommending them to others.

I have used Gareth and Tom for a number of years and have recommended them to numerous friends and Neighbours. They are very responsive, punctual and extremely polite. Their annual service is very thorough and much better than the very large national company we used to use. All work is explained and carried out as per explanation. They are very clean and tidy and one they leave the property you do not know they have been there. Am excellent example of a Local business serving the local community and with the added benefit of being Welsh speaking.

Over the last 3 years Gareth and Tom at Heatglow have installed my home combi boilers, underfloor heating and new radiators. On top of this scheduled work they have responded to call outs for frozen pipes etc. Not only is there service excellent, the quality of work has been outstanding. Additionally, they are very careful and respectful. It is not often that rooms are left tidier after a callout than they were before.

New boiler and small radiator installed. So professional and reliable, unlike many tradespeople these days! I immediately felt comfortable having them in my home. Work was completed swiftly, on time and as per quote. The price was also competitive and good value. Gareth was approachable and offered lots of help and advice, beyond the work that he was carrying out. Aftercare was also excellent. I can not recommend this company highly enough! Do not hesitate to have them carry out work for you as they will exceed your expectations!

Gareth and Tom have serviced our boiler regularly since 2015. Always with efficient and friendly service with a smile. A call out on December 5 for heating failure needed a valve replacement in the boiler. Tom came at the end of a long working day. He had to drive miles across Cardiff during rush hour traffic for the part. Then all the way back , still during rush hour, to do the job, which was a long one, without complaint about either the distance, heavy traffic both ways or his late finish after completing the job. Highly, highly recommended and have recommended to friends who have used them for boilers and bathroom replacement and were equally delighted. So glad a friend recommended them to us. An added bonus that they are Welsh speakers!

Tenants at a rented property were left without hot water when an old boiler broke down. Heatglow replaced the boiler within days. They were professional, communicated the options well and once I decided on the best option got to work straight away. This was 18 months ago and we haven't had any issues with the new boiler.

Gareth was able to call the next working day to look at our problematic heating which another company had left unresolved. He identified two faults which he explained in clear terms and quoted a reasonable price for fixing. He had both the required parts with him and did all the work within two hours. I shall be using HeatGlow without hesitation for any future heating and plumbing work.
