Great company
My whole experience of Think Green was positive, from the initial consultation with Mike to completion of the work. Everything was done to a high and professional standard and I am very pleased with the result. I also feel safer in my home. Thank you Think Green, I would happily recommend you
Jonathan from GTP - what a great guy
Jonathan the guy that came to give us advice on our existing solar system which has been failing us was a very personable, knowledgeable young man. Most of all he wasn’t pushy. He showed my husband all around the system pointing out failings which all pointed to a poorly installed system in the first place. We were under no pressure to make a quick decision but we have decided on a care package, new wiring and new batteries, we were very happy with the company. Jonathan came on Wednesday and they are here today fitting it all.
Trapped
Did not realise that T.G.P.are only middle men, who send out other companies to do the work! They sent someone to me who had travelled from far too far away. He was a really nice guy, but did not fully understand my system which I had specifically asked for help with. I'm now trapped in a contract with T.G.P. for 5 years.

THINK GREEN PARTNERS
Marc, the sales guy was very thorough with both the system survey and information relating to its day to day usage. We have now signed up for the comprehensive 10 year cover plan which included a yearly service and clean. Obviously, we currently have no experience of how efficiently problems are resolved, but, for now we do feel confident that we made the right decision with the purchase and using THINK GREEN PARTNERS.

Had my inverter installed in 10/2024 asked s few questions, everything sorted.
Better than average by a good distance
This is definitely a much better company than the usual Solar company. We had some issues after the installation but they responded so quickly and sorted out the problem all the fitters were polite and good and special mention to Luke head of installation who responded so quickly and efficiently good company I would recommend
The installation was seamless
The installation was seamless. The team worked quickly but carefully, and they left everything clean and tidy afterwards. You wouldn’t even know they’d been apart from the great new system!

Aggressive and deeply unprofessional sales behaviour after cancellation
We were initially contacted by the marketing team at Think Green Partners and offered a “free assessment” of our solar panels. After some persuasion, we agreed to a survey, which was carried out by their engineer, John Henderson.
During the visit, we were sold a 10-year maintenance plan for £4,000. As we did not have the funds available to make a one-off payment, John then assisted us in applying for an interest-free credit card in order to pay for it. We were also told that our inverter was broken and were offered a “free” inverter replacement if we signed up to the 10-year plan.
After taking time to think about it and doing some research, we decided we were not comfortable proceeding and exercised our right to cancel. We contacted the company by both email and phone to cancel the plan.
We were told that John would call us to explain the next steps.
What happened next was absolutely unacceptable.
When John phoned, he initially seemed unsure why he was even calling. Once I explained that we had changed our minds and cancelled the plan, his entire attitude changed. The conversation quickly became pushy, confrontational, and deeply inappropriate.
For around 20 minutes, instead of simply accepting our cancellation professionally, he repeatedly questioned our decision and demanded to know what we were going to do about our broken inverter and cleaning/protecting the panels. I explained that we had our own plans in place, but he would not let it go.
He then went so far as to start making personal comments about my son, questioning whether he was qualified or insured to help us, and even *googled my son’s workplace during the call in an attempt to “prove” his point. This was completely outrageous, intrusive, and none of his business whatsoever.
Even after I clearly told him that:
* our family arrangements were none of his concern
* his assumptions were inappropriate
* his tone was becoming unpleasant and unprofessional
* and that he needed to accept that customers are allowed to change their minds
…he continued.
He then tried to pressure us again by offering a **5-year plan for £2,000**, while claiming he was “not being nasty” but was “very offended.”
Let me be clear:
A customer cancelling a service does not justify being spoken to in a pushy, berating, defensive, and frankly intimidating manner.
By the end of the call, I felt extremely shaken, angry, and upset. I had to hang up because he simply would not stop.
This experience has completely destroyed any trust or respect I had for both John Henderson and Think Green Partners. What began as a professional interaction turned into one of the most uncomfortable and aggressive sales follow-up calls I have ever experienced.
My advice to others:
Be extremely cautious.
If you decide to cancel, do not expect that decision to be respected professionally.
This felt less like customer service and more like harassment after cancellation.
No customer should be made to feel pressured, interrogated, or personally criticised for exercising their right to change their mind.
Based on my experience, I would strongly advise anyone considering this company to think very carefully before signing anything.
Absolutely unacceptable customer service.

First time
This is my first time I used them to clean my 66 panels and they did a great job.I went in a 5 year agreement that includes 2 cleans a year.

I’ve been trying to be a customer of TGP for about two months now. Had a call about fitting pigeon protection to my solar panels, had the engineer out, expected a quote. Nothing. Asked for a call back, nothing, left voicemails, nothing. Got a quote on the phone, asked for it to be emailed. Nothing. Promised an email by the end of the day. Nothing. It shouldn’t be this hard to give someone your business.

Each year they come to service my system, they persuade me to spend money, this year I had optimizers fitted as I was told my system had high voltage, last year I paid what I thought was more than necessary, and again this year, I am not an electrician so I am having to trust that I am not being sold something I don't really need. When I purchased the batteries, I was given a 10 year guarantee. ! I cannot afford to keep paying out money every year

Speedy and professional service
Adding an extra battery to my system took little more that 15 minutes and was done and in use in that time. I am very happy with the service and the continuing support I receive from TGP
