The right person answering emails

Very good experience. My anxiety got the better of me and I emailed to enquire about delivery. I was contacted by, i think his name was Jack, who kept in touch until the item was dispatched. Item received, installed and working perfectly. Give Jack, if that's the correct name, a clap on the back😁😁

Excellent service.

We have used Glow for a new boiler and also to replace a radiator. On each occasion we have been extremely happy with the quality of work. The fitters have been courteous and efficient and done an excellent job. Recommended to family who have also had the same quality of service. Would definitely recommend Glow.

Incompetent and take no accountability

Incompetent engineers damage property and they take no accountability.
Before carrying out the work they failed to disconnect the water supply, so when they sawed a pipe open water came flooding out into the room, damaging a computer, all captured on a security camera.
When talking to them they said they'd arrange for it to be repaired which they did not, they also handled some other belongings recklessly by bashing into them and throwing them luckily no damage caused.
They never arranged for the computer to be repaired, they had to come back multiple times after the job was completed to carry out other minor work and to fix issues, the computer was mentioned each time but with no resolution.
Due to being disabled this computer is my only connection to the outside world and I had to go into debt to fix it myself.

Do not use glow.

Hi Amy,

Thank you for your feedback.

The heat pump installation was instructed to us by the landlord/local council at your mother’s property. During the week commencing 02/12/24, there was a small leak during the heat pump installation. This was related to a dead leg of pipe that was already partially drained.

After the installation, your mother, Rebekah, who is the responsible person for the tenanted property, informed us of your concerns. We immediately arranged a visit, which took place on 12/12/24 and this visit was fully documented. Our lead engineer, Alan Johnson, attended the site and spoke with your mother to look to resolve this issue. He offered to take the computer to a local repair shop for independent assessment, but this offer was declined. Instead, your mother chose to arrange the assessment herself and agreed to keep us updated. Evidence of this conversation is time stamped/dated in our job management software.

We requested to be informed once the computer had been taken for inspection. To assist, we provided details of a local repair shop near your mother’s property. When our engineer Ben attended on 17/12/24 for follow-up work, he also inspected the computer, taking images and videos, which we still have on file. He found no visible signs of water damage, and the computer was notably dusty. During this visit, Ben reiterated that if an independent assessment confirmed damage as a direct result of our work, we would cover the costs. However, we were again denied permission to take the computer for inspection ourselves.

As a company, we cannot issue financial compensation without verifying claims through an independent third party. This is a standard and reasonable request, which was initially agreed upon. Unfortunately, you proceeded with the repairs independently without providing us with any evidence of damage.

We are disappointed to receive this review, as we were not given a fair opportunity to resolve the matter. Additionally, this complaint was never escalated to us directly or to the council, which would have allowed us to address it formally.

If your computer was indeed damaged as a result of our work, I sincerely apologise. However, we have made every reasonable effort to address your concerns fairly directly through your mother who is the named tenant at the property where your computer was located.

Best regards,
Jack

Pump replacemnt

Once again Glow Heating Services surpassed themselves with excellent service from the office staff to the engineer. I was kept in the loop from initial contact to the end of the job. The pump was replaced quickly and efficintly, no mess. Having had my fair share of cowboys in the past I have no hesitation if highly recomending this company.

Annual boiler service

Just had our annual boiler service. Great communication from both the office from Millie when needing to rearrange the appointment and Josh, the engineer. Text and call to advise he was on the way, service done professionally and considerate of property. Highly recommend The Glow Group, thank you

Very happy customer who has just had a new boiler installed

We have just had a new boiler fitted by Alex & Dane and have to say, what an excellent service they provided. They arrived promptly each day, worked conscientiously and were polite and professional throughout. Their workmanship was first class and each day they tided up before they left. We are very happy with the service we have received and more than happy with the new boiler. Thank you so much.

I would also like to thank the office staff, who have made the whole process straightforward and stress free. I cannot recommend The Glow Group highly enough.

Air source heat pump

We had our heating system redone with The Glow Group, new pipe work everywhere and an Air Source Heat Pump installed. The team took 1 week to install, everyone was really nice, took the time to speak with us and made sure everything was clean and tidy after each day. Dan was especially hard working, first to arrive and last to leave. Teething issues with the system have been sorted promptly with great comms between Jack, the office and myself where necessary. Truly professionals who love their jobs. Thank you so much.

Great service

Been meaning to write this review for a while. Had glow to change our boiler last year changing over to a combi. Great people and service and advice. Had them round since for minor problems and speedy service and sorted no problem. Highly recommended

Avoid. Used to be great but really not any more

I used to rave about The Glow Group and actively recommended them. Not any more. We had a brand new boiler installed and it leaked water through the house, they came out and the guy was quite rude but replaced a part. A few months later, water through the house again as it hadn't been fixed properly! We had their Glow Plus service and wanted to book the service in as it was included and then cancel the Glow Plus extra. We were told that the boiler was serviced when it was installed and that we could only have a service if we paid for another year. Who services a boiler when it's installed?! It's such a shame as they started really well. We cancelled the Glow Plus and was told to cancel the DD which we missed the date for and they have a payment of ours in their bank so now have to try and get that back. I really would no longer recommend.

Gold star service

Contacted The Glow Group after being let down by British Gas. From the very first message the service I received was A1. Had a couple of hurdles to jump due to boiler location but everything was dealt with efficiently. I was kept informed along the way. Jack & his team go above & beyond . Will not be using anyone else now

We have used the Glow Group several times. Jack fitted us a new hive heating system and his service couldn’t have been better! Can’t recommend him and his team more. Professional, personable and definitely reliable!

Wonderful Local Heating Company

Our heating went down last week. Having had our boiler fitted with British Gas we attempted to get in touch with them, despite us having a 6 month old baby in the house the best appointment they could offer was over 3 weeks! Several friends recommended Glo Group and we are so glad they did. Calling and speaking to an actual human who was super helpful and an appointment with an engineer was booked in for less than 2 days away was a great start. Superb. The engineer was on time, professional and got our system working again in less than an hour. We have signed up to one of their monthly plans given how impressed we are with this company.
