Glow Green Reviews 

Had a bad start 2 cancellations then Saj came. He is a young lad maybe 34 and said if I want to know anything just ask. He explained how the procedure worked and how his work is checked by his boss to see that everything was as it should be. The people who sent the flue sent the wrong one and Saj had to go to Dundee to get a replacement. He finished at 8.30pm with only the cementing to do but it was dark and raining. He came back next morning at 7.30am and finished the cementing and checked the boiler ,set the wireless programmer. He was so relaxed and pleasant when he was speaking and said 'My lovely'at the end of his question. 5 stars and more.

Service engineer phoned on Sunday to say he'd be here on Monday at 0800 - 0900.
First service of the day.
He arrives at 0910 and says he's sorry he's 10 minutes late due traffic.
I told him I'd been waiting since 0800 - like he asked and arranged - why didn't he call? No reason. Just didn't bother.
Inconsiderate and disrespectful of my time.

Edit 1 : A very professional manager from Customer Services contacted me quickly to apologise for the less than professional service from this particular engineer. Hopefully he will be re-briefed on importance of punctuality.
Thank you 'Y', much appreciated.
Edit 2 : I have changed my star rating to 3* to reflect the excellent customer service offered by GlowGreen HQ. Can't fault their response.
It's still 1* for the engineer but 5* for GG Customer Services , so average = 3*.

the engineer was knowledgable very friendly and gave us confidence oin his work

The price was good and the panels and battery were installed when promised.
On the other hand, after installation, they haven't been proactive in keeping me updated about the MSC certificate or when the scaffolding will be removed.
Overall, I recommend Glow Green.

Engineer was Friendly and pleasant ,got straight to the job efficiently and thoroughly.

Fantastic service and great communication

Arrived within the scheduled time slot. Carried out the service in a thorough and tidy manner. Everything was left as it was found.

Iuke very nice arrived on time and explained every process on the boiler which was first time since i had boiler installed,now i understand the boiler more.

The first engineer sent to fit a new boiler failed to arrive. No reason given.
The second did arrive but decided the job was complicated and left.
The third was very competent although his mate made a mistake resulting in permanent water staining on wallpaper.
Three weeks elapsed between first proposed fitting date and actual fitting!
It appears Glow Green is accepting more work than it has competent people to undertake and seem unconcerned.

Very easy to book a service for the boiler…customer service and communication very informative and very helpful…the engineer answered all my questions and queries professionally…taking time to process and answer the same…would encourage anyone to use this excellent service…

The new Vaillant EcoTec Plus 836 was virtually a like for like so the installation was quickly completed with upgraded kit as required.

I informed the supplier that the hot water supply was poor in comparison to the original 20 year old Vaillant EcoTec Plus 837. On inspection it was found the water supply was being restricted due to an undersized water softener which has now been replaced. I understand they won't be using this type again on high capacity boilers.

The new boiler is very quiet.

We started the process of getting Glowgreen to install our solar panels and battery on April 24th 2026. Now it is September 18th 2026.
Glowgreen is a very disorganised company. it displays poor inter-department communication. the materials to be installed were delayed 3 times before delivery. No explanation was given. The actual installation date came and went twice without anyone showing up: 23 days elapsed between original date and actual date of installation. The installation was not finished though and we had to wait another 34 days (during which time we had to chase Glowgreen repeatedly via phone and email) before the electrician returned to finish the job. the scaffolding is STILL UP despite being given 2 dates on which the scaffolders were due to dismantle it. Nobody showed up. In total we have spent 5 days waiting at home for Glowgreen's men to arrive. No explanation was given for these 5 no-shows. Just apologies and then silence. The scaffolding has now been up for 100 days. We have no idea when it will come down. We really regret using Glowgreen and recommend you give them a wide berth.

Amer, the engineer, from Glowgreen, who came to do my annual boiler service was friendly and professional. He explained what he there to do, was efficient and worked quickly and made sure he tidied up. An excellent service- I would be happy to recommend him as I'm sure he'd do a good job wherever he is sent. Marks out 10? 10 out of 10 for Amer and Glowgreen.

We had our boiler serviced again this year and had the pleasure of Luke for the 2nd year. Luke always asks if we have had any issue with the boiler, then gets on with the service. He engages with us to make sure we know what to do if there is an issue. He is always pleasant and professional Thankyou Luke

Mike. Arrived on time. He was very friendly and chatty. Explained everything. Did additional checks. Great guy

It was time for my annual service on the boiler, booking a time is a bit of a slow process as you can’t book a slot you have to wait and see when they can fit you in. Patrick the engineer who came was very polite and called when he was on his way he apologised that he had to come back as he needed a part. He left making sure everything was safe.

All great , happy with the service.

From the first call to ordering it found the experience so easy, was informed every step of the way.
The engineer James was lovely, very polite and knowledgeable.

From start to finish glow green have kept me informed, what was going to happen. When it was going to happen. Both enginneers turned up on time. Went through the installation, were I wanted the AC unit going etc. Rob and Stuart both did a good job. Very impressed. Spent time after going through how the unit works. And what to expect. Would recommend glow green for your AC installation.

Boiler service - engineer was friendly and very efficient.
