Glowarm serviced my boiler for many years and I was very happy with the workmanship. I had a new boiler and 3 radiators installed within a day and to budget. The fitter arrived on time, carried out the work efficiently and left everything clean and tidy. This included alterations to the kitchen cupboard housing the boiler.

I needed my central heating completely replaced, with additional radiators, but retaining the current boiler which is only 5 years old. The price was by far the cheapest of the 4 companies contacted, and whilst one company advised it would take 10 man days, the engineer / installer only took 3 days. All pipe work was neatly done, including work under the floorboards. My house is on 3 stories, but this caused no problems for Glowarm. The was no damage to the property, and upon completion, everything was tidied-up and cleaned. There have been no leaks and the new radiators are really efficient. I am really pleased that I employed Glowarm, and I would recommend the Company to my friends.

The job was to install a new boiler and new pipework and attach to existing radiators in a 1930s flat, detaching the existing system from the estate-wide heating system, so creating a self-contained heating and hot water system for a 3-bed flat. Everyone in Glowarm did their job very well - from the initial survey and quote from Richard (this was done a year ahead of the time slot booked), the actual work undertaken by Mark and Gary and their sons, and the admin undertaken by Barry. The works were done on time and to an excellent standard, and some good solutions were achieved to the complexities of the project.

Glowarm were mandated to install and commission a new independent central-heating (combination boiler) with new radiators and a towel rail and new hot and cold water pipe systems in my entire flat. The team of plumbing engineers who executed this work did an excellent job - their workmanship was of a very high standard, they were neat and very tidy during the entire installation process. Glowarm consulted with me at each stage and, importantly, were prompt in responding to my queries with clear explanation and practical advice. Well done the team!

Glowarm were one of three companies I approached for a quote for a new boiler. I had a face to face visit immediately from them and an honest quote. The other two kept messing me about and wanting me to take photos of my old boiler and plumbing and email them to them. Then they kept emailing and phoning me without referring back to their old phone calls or emails and asking for more information. They came across as incompetent. Glowarm were a local (Mitcham) independent, long established family company who proved to be fast, efficient, reliable and professional. I would recommend them without hesitation.

Great service from the team at this company from quote to supporting us through all the after installation snags. Customer service was excellent throughout. The installation team team was very friendly and efficient, no matter what, turned up after hours when we had concerns and always helpful. Replacing a boiler is a big thing, and it was very re-assuring to have the installation manager and the team listen to our concerns, give help and guidance, do the necessary to check on things, and re-assure and support us when it looked like we may have a major problem. Fortunately it turned out to be a small thing with a big impact, but you held our hands all the way. Thank you.

I had a warranty for my old boiler which was over 10 years old which had been serviced by Glowwarm, for a number of years. All prior services and repairs work carried out by Glowwarm with no problems whatsoever. And I guess my old boiler had seen better days, upon a standard repair I was made aware, it was no longer cost-effective. The old boiler was in a built in cupboard, which I was worried about in regards to the new boiler being able to fit in it. True to the engineers word, the new boiler fitted in it with no problems, excellent job carried out from start to finish. Thank you Glowwarm *****

New boiler and radiators
The sales engineer visited, and explained what type of boiler would best suit our needs, making a saving on what we had expected. This meant we could also change some old and inefficient radiators. The installation team came on time, were efficient and tidy, were able to add an extra radiator at short notice. All men were very helpful.

From the initial visit and quotation through to completion of the installation, I cannot praise this company enough. I have to confess I was dreading having a new boiler - you hear such horror stories about the mess and inconvenience and I have cream carpets in the bedrooms. So I was very pleasantly surprised when the engineer completed the work efficiently and cleaned up any mess that was made. The only way I know I have had a new boiler fitted is because the house is warm and snug. Thank you.

I first used Glowarm Ltd around 14 years ago to install my heating system. The customer service and quality of work then was 1st class. They have always serviced my system. Again customer service 1st class, so I did not hesitate for them to install a new heating system. Their technical surveyor was most helpful. The work carried out by the gas engineer you could not fault in any way. Again, first class work carried out by a first class company.

After shopping round for 4-5 quotes, Glowarm came out with one of the most competitive for our boiler replacement. They clearly aim for high customer service and also know their stuff. During the installation itself they were let down by the no-show of an electrician they had sub-contracted, but apart from that they were great. Even when the project turned out to be more complicated than first thought, they came up with good solutions and didn't charge extra. Very tidy, good standards and a pleasure to deal with.

Quick and Smooth. Answered all questions/clarifications. Very friendly. Finished much quicker than told. Very happy and pleased. Will recommend. One recommondation. I realsed that one of the plumber had "something" on their shoes which created a kind of stink in the house. When the Virgin Media guys came to setup the broadband they wore a kind of plastic cover over their shoes just to ensure nothing stays behing. You can implement the same idea to leave nothing to chance. Nice work otherwise.

Gary was most professional at all times and took a pride in his work. He explained to me at all stages what he was doing.

The arrival of the electrician was spot on as was the initial delivery of the boiler itself. I cannot emphasize enough how pleasant the whole experience was.

I cannot fault the whole experience in the installation of my boiler. Gary arrived punctually on the Monday and immediately set to work in a calm and efficient manner. He had removed the 3 tanks in the loft (unruffled after I had stated I thought there was only 1). He cleared debris at all staged, tidying up as he went along. The airing cupboard tanks despite their bulk and weight were removed as was all related piping. The preparation for the insertion of the boiler was exemplary.Review 1 of 2
