Thank you for your feedback. We are disappointed to read your review, as it does not reflect the circumstances surrounding this installation.

The installation was completed in accordance with the agreed contract. However, the system could not be brought online due to issues with your internet connection. As discussed at the time, the wifi was not connecting correctly, which prevented the system from getting online. We also discussed the star link WiFi connection with you to boost the signal.

In an effort to assist, we made multiple visits to your property to diagnose and resolve the connectivity issue, despite the internet service being outside the scope of our installation. You subsequently arranged for a third-party engineer to attend and investigate the internet connection, and we worked cooperatively throughout this process.

We also offered compensation as a gesture of goodwill for the inconvenience caused, despite the underlying issue relating to the internet service rather than the installation itself.

We always strive to provide a professional service and are disappointed that our efforts to assist beyond our contractual obligations have not been acknowledged.

Professional and prompt service

After falling prey to previous rogue companies that have disappeared when needed, TGP are in a league above. Their smart, polite and professional staff give me confidence that they will still be around if needed in the last ten years of my FIT period. Regular inspections and calls from their compliant team are reassuring.

Aggressive salesman

I am writing to complain about the conduct of one of your engineers, John Henderson.

I requested an engineer to come and give us, me and my elderly mum, a no obligation quote for a clean and service of my solar panels and equipment.
On arrival John spent ages showing us power points and trying to sell us a voltage optimiser as he said the voltage into the house is too high which is affecting the use of the solar.
After a while and thinking that we were not going to learn anything else, information overload! I stopped his presentation stating that we needed time to discuss and research what he had told us. I thanked him for coming and said we would contact him if interested.
John ignored me and carried on showing power points and repeating what he had already told us.
John then said he would go outside and make some calls for ten minutes before returning to hear our decision. I asked him not to come back as we needed time to decide and weren’t going to make a decision today.
John then became very pushy asking why we needed to do any research as he had just given us all the facts, he then started showing us more power points, phoned head office, dropped the price, offered to help us to get a no interest credit card.
I must have asked John to leave about 10 times. My 83 year old mother also asked him to leave. John said there is something wrong with you! He also asked why I was being so horrible to him. I told him because he was being too pushy and wouldn’t leave.
John asked if I expected him to tell me what was wrong with my solar set up for free. I said yes that it was a no obligation quote to fix whatever may be wrong and because he was being so pushy I wasn’t going to buy anything off him.
John finally left after my mum shut herself in her bedroom and I opened the door and stood in the back garden so people could hear me telling him to get out of my house. I thought at one point I was going to have to call the police.
We both felt very intimidated and vulnerable and were shaking after he left.

This is the sort of aggressive and high pressure sales tactic that needs to be reported to trading standards.

I also noticed that this particular engineer has been mentioned on Trust Pilot for being aggressive in his sales tactics.

Thank you for taking the time to share your feedback.

We are very concerned to read your comments, as the experience you have described does not reflect the standards of professionalism and customer service we expect from our team.

Our engineers are trained to carry out a thorough assessment of a property's electrical and solar system before discussing any recommendations. We do provide information on products that may benefit a customer's system, but we expect all recommendations to be presented professionally and without obligation. If a customer indicates they do not wish to proceed or would like more time to consider their options, that decision should always be respected.

We take allegations regarding high-pressure sales tactics extremely seriously and have begun reviewing the details of your visit internally. We are committed to ensuring that all customer interactions are conducted with courtesy and respect.

We would welcome the opportunity to discuss your concerns further and establish a full understanding of what took place. Please contact our customer service team directly with your address and the date of your appointment so that we can investigate this matter thoroughly.

We appreciate you bringing your concerns to our attention.

It is early days, but first impressions have been very good. I have found all the staff that I have connected with to be efficient and polite. Service so far has been excellent

Thank you TGP & Ricky!

Had issues on my battery system - Ricky came out and checked all my system and took the time to explain how it’s all running and what the issue was. No pressure tactics like most companies and got the issue resolved promptly. Installers came and did an amazing job.

Thank you TGP & Ricky!

They charge VERY high prices compared to other firms for doing the same job . They bamboozle you with the prices and what needs doing I was charged way higher than I understood .
According to my bank what they are doing [is a good job for some people and very much scamming old vulnerable people ] which is Bad Practice but not illegal.
I would advise ANYONE who is approached by them to get quotes from other firms and leave them well alone .That's a very polite way of puting what I think of them.

Thank you for your feedback, Sara. We are sorry to hear that you are unhappy with the service provided.

We would, however, like to clarify a few important points regarding your installation and agreement with us. The work carried out included both the supply and installation of goods, together with a service plan. This plan provides cover for parts and labour for the entire system for a specified number of years, which was fully explained and agreed to prior to proceeding. This level of cover has been selected by many homeowners across the UK.

At no stage during the point of sale or installation process was any concern or dispute raised, and all documentation, pricing, and terms were accepted before the work was completed.

The installation was carried out promptly, and the compliance process was completed successfully with you, including all required checks and procedures. Following your later cancellation request, the matter was reviewed, and the maintenance plan was subsequently cancelled, with a refund arranged accordingly.

Our pricing reflects the quality of the products, installation standards, level of service, and aftercare support we provide. We fully appreciate that customers may wish to compare quotations from other companies before making a decision, and we always encourage this.

We respectfully reject any suggestion of wrongdoing or misleading conduct. We believe we fulfilled the agreed contract professionally and in accordance with the agreed terms.

We wish you all the best moving forward.

Thank you for your review.

We would like to clarify that we are a solar company and specialise in electrical and heating services. We do not deal with damp, ventilation, or insulation matters, so we are unable to advise regarding loft insulation or foam insulation concerns.

Hassan is a member of our team, and during his visit he would have discussed the current status and performance of your solar system, including the inverter output, along with any options available to you regarding the system. There was no obligation or commitment required from our side.


We aim to provide support and cover for solar and heating customers across the UK, and we pride ourselves on delivering a professional and honest level of service to all of our customers.

Thank you for bringing your concerns to our attention.

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.

In light of this, we kindly ask that you either remove or amend your review to reflect the correct information.

Kind regards,

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.

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!
