Glow Green Reviews 

I opted for GG having had a very helpful and patient sales person advising, having had a reasonable quote, and having seen their very good Also TrustPilot scores and independent reviews.

On the positive side
The panels and battery were eventually installed and are working fine.
Most of the tradespeople were good (especially the electricians and the roofer who had to work solo because his mate was called to another job to cover illness).

Problems:
1. Delay.
GG quote
Got quote and paid initial deposit 11 Dec 25, contract signed 19 Dec. Scaffolding booked for 18 Mar; installation finally completed 30 Apr 26.
I was warned getting DNO (Grid) approval could take a number of weeks and cause delay. This was achieved by 9 Jan 26.
Turned out the scaffolders were sub-contracted (to a less-than reliable firm) as part of a sequence of other factors which delayed both installation and removal.

2. Wrong roof tiles
Part of the delay was because the assessment of the roof was by photo and they depended on me to advise the type of roof tiles (put in 25 years earlier). I'm not a builder. It turns out the panel rail fixing brackets were for a different type of concrete tile so the first installer had to await different brackets arriving.

3. Comms.
During these nearly seven weeks of installation I got little useful help or information from the various people I rang and emailed. It was always 'sorry', being 'chased up', or 'looked into', but no actual explanation. Also, see #7 below.

4. Tesla refund
I was initially told there was an offer of £750 refund with Tesla batteries. It turned out that it's £325 per battery for up to two batteries. I only had one battery.

5. Waste removal
Our garage was full of waste which took 8 days to be removed. The car had to to be left outside for this period. I had assumed the installer would take the waste with them when they finally finished the job and left but it needed a separate subcontractor to get the job done.

6. TV reception
After installation, the TV reception was significantly impaired and we had to get a TV person in to diagnose and resolve the problem (the aerial in the roof space needed to be moved to a different place away from directly under the panels, and have a signal booster added).

7. Follow-up
On 25 Apr (i.e. before the rubbish had been cleared and Before the final payment made) I was approached by GreenGlow for feedback about the installation. I was too annoyed at that stage to give considered feedback. It has taken until now for me to feel able to do so neutrally.

In short: the seven week installation period was *very* frustrating indeed (1/5). Once the work was finished and waste removed the system works well, though (5/5).
Thus overall my 3/5 score.

Fitter luke great service great good comunication from office and fitter thankyou

The staff was very professional, respectful and quick to do the servicing.

The installation was flawless and Conner the installer was a true customer service individual as well as being very friendly. The electrical installation went better than expected and Chris even came back in Friday evening to check in a problem which was not as a result of his work - in this day and age truly great service.

Sean was very thorough with the boiler service. Clean and tidy and I felt that he had taken extra care to make sure everything was safe and well prepared for the winter.

Great product boiler and price. The installation went well and we are happy with our new boiler. Would recommend this service to all.

Installer was great. Initial boiler was incorrect and didn't fit despite providing measurements and photos. Didn't know when different stages were happening including collection of incorrect boiler or delivery of new one. As mentioned the installer was great and got the challenging job done professionally. Still having issues with finance agreement being messed up and to be fair we're not sure if that's GlowGreen or finance company but frustrating all the same. The customer care team at GlowGreen are friendly and seem to be limited by red tape in getting things done. All in all we probably wouldn't recommend using them but would recommend the installer.

Fantastic service

We had an agreed date for installation, so I booked my last 2 days annual leave. The scaffolding was supposed to go up 5 days before. This was agreed, so my wife stayed in all day, no show. To be told lunch time the consecutive day. No show. Then the Saturday, so I stayed in, no show. They turned up the Monday.
Installation started, but had to be stopped scaffolding loose and insecure. No sign of electrician.
To then be told scaffolding needed to be redone.
Solar panels finalised on 3rd day. No sign of electrician.
Some nearly a wk later electrician sorted it all.
With all the issues I was told the DNO would be prioritised.
I then got an aftersales call, went through it all, to be told the DNO would be prioritised.
10 working day after install, no signs of DNO. Called to be told it would be prioritised.
1mth on and its still not completed.
So much false hope, so many will do this, will do that.
I seriously would recommend anyone else. Please do not use.

Fantastic value for money, easy service to use. Great customer care and after care

Mike, my gas engineer contacted me on the day to give me a three hour window for my appointment.
He arrived within this time slot and was friendly, professional and efficient in servicing my boiler.
Thank you Mike.

I had a solar and battery installation that just did not go well from start to finish:
-Appointments were not kept
-Installation was delayed months
-Customer service was unable to explain delays
-DNO certificate withheld for over a month
-Feedback was provided directly to follow up team and nothing has been heard since.

Not impressed at all!

Excellent service from Mike. Professional, punctual, knowledgeable, and very thorough. He serviced my boiler efficiently, explained everything clearly, and left everything clean and tidy. Highly recommended and I will definitely use his services again.

No nonsense engineer - helpful and courteous. Went the extra mile and stayed late to meet Cadent engineers when problems discovered with incoming mail gas pressure

My boiler service was due in September as i have a yearly subscription to get the boiler serviced and this was arranged through glow green who ensure that a convenient day and time appointment is booked and they send me an email confirming the appointment.
This works well for me and is easy to arrange through glow green and they have never let me down.

Boiler serviced by Patrick, great guy. Clean and tidy

The engineer was friendly, efficient and considerate. He gave the boiler a thorough service, with a running commentary (mostly to himself) as he worked! He also found that a filter had not been cleaned properly on a previous occasion. We appreciated being informed in advance of the initial delay, and then being told when Sean would arrive. A good service!

In my recent search for suitable companies Glow Green stood out - in particular, Connor who was my contact at Glow Green. Connor was polite, considerate, effective, communicative and concise. He was very good to deal with.
