Grant Store Ltd (GSL) - Solar & ASHP Installer レビュー 

The surveyor from GSL (Grant Store Ltd), conducted a thorough assessment for the installation of equipment needed to increase the energy efficiency and ventilation of my property. He explained an outline plan for the improvements, which I clearly understood, and am happy to proceed with the programme.

A young man called John came and fixed our boiler he explained everything that needed to be done he showed us the part that needed changing and what had broken he was very polite and we wouldn’t hesitate to have him back excellent service

The last day of the full installation was the electricians, Andy, Mike & Jack. Friendly, skilled and very efficient.
Overall GSL are outstanding.

Martin &garry arrived to fit the central heating they both worked none stop and we couldn't fault their work it is very neat and tidy , both were very pleasant and professional

I had solar panels and battery fitted. Everyone who was involved was great.from scaffolder who called to let me know he was running late, the team that fitted panels were so efficient, and neat and tidy, right to last team who were electricians. Really pleased all working well so far.

Ryan Fowler & Rhys jay done a amazing job job stripping walls n cleaning up after them selves

Yesterday I had the pleasure of having Mark , the electrician from Stockport come to my house to carry out work to my new boiler ....he did a great job and was very helpful explaining how everything worked . He even gave me his own personal phone number in case I had any further problems with the hive WiFi system. Thanks again mark ...great job.

Two great lads arrived to fit our central heating system, Martin and Garry they worked nonstop and had the system working perfectly. They came back the next day to check that everything was running smoothly and did the paperwork. There work was carried out professionally with no problems and no mess very much appreciated. Thanks.

This company has been great from start to finish. We had some pipes that needed covering. The company booked in a joiner, Kenny Hughes, who came and carried out the work to a very high standard. Everything was left clean and all looks very neat. Very happy with his work!

We recently had solar panels installed by GSL. Just wanted to praise the electrician Ash and apprentice who completed the work. They were very knowledgeable and tidy workers and respectful to our property, would highly recommend them.
Thank you Ash

This company has helped us all along the way with our installation of solar panels and a heat pump heating system.

Today 2/06/2025 we had exceptional help from John. He was patient, thorough and very helpful.
However everyone who has come out to work have been great. Since the work started on the 10th March. I would also like to mention that Zoe who works in the office has been very helpful to us. Thank you everyone.

work is excellent, his attention to detail is second to none. 10/10 with his work ethics, left everything as he found it.

Kenny Hughes was great, turned up on time. Friendly and polite. Did a great job of boxing in pipes and extending a cupboard. Lovely neat tidy job. Thankyou.

1.Surveying - 12 panels quoted "found out day of install", no way could 12 panels fit in my roof "this seems to be a common theme looking at your reviews.
2.Quote had additional fuse board which was informed not required as a new board had been installed with 6 spare RCDs
3.Quote received after corrections, 12 panels hybrid inverter proceeded with quote, then got called to ask if I wanted to have batteries at some point if so would need hybrid inverter, explained it was already on the agreed quote and contract, was agreed quote was ok to proceed. I was then called 2 additional times asking the same thing and again agreed it was fine, was called a third time and told you would only proceed with a panel install if I didn't pay so I had to pay for batteries for you to install. This is extremely concerning engaging in this type of behavior.
4.Scaffolders never turned up, called 3pm told they will be here never arrived.
5.Scaffolding still up - whens this coming down?
6.Installers confirmed no chance 12 panels will fit offers £78 refund for each panel, the survey should have picked this up, this seems another common theme over quoting for equipment
7. Electrician called Togo a car charging job "why" at 3pm returned 6:30pm finished 9:30pm, this is not ok, not his fault.
8.According to MCS cert must be issued within 10 working days along with installation pack, never happened till chased.
9. According to contract remaining invoice to be paid on completion, you are now advising this is not correct.
10.DNO was not requested until a month after I agreed the quote even though I was informed it was submitted, obtained the information from National grid show GSL where just misinforming me.

Update Scaffolders turned up today unannounced no knock at the door threw a ladder up to the bedroom wife was in while she was getting changed, Lorraine at GSL advised not their problem.lucky got ring cameras up which shows them entering the property unannounced.

Wonder how they would feel someone looking threw the window while getting changed and not knowing and the company saying not their problem.

With regard to my earlier review..Following instruction from the surveyor the vent was fitted as instructed. After contacting the company to complain, the fitters Ryan and Rhys are back today to remedy the problem. I realise now that they were following instructions. Well done lads the new placement is great. Thank you manager Chris,for contacting me with an explanation and getting your lads here to sort the
problem.

Dave Joyce was very efficient and understood balancing requirements against aesthetics of the install. Very helpful, friendly and efficient during the drawing/survey stage.

Very easy to deal with and really pleased with the installation.

Well pleased. Good product, speedy installation, and good service. Best of all - a great price.
Thank You.

This has been a seamless process from end to end with timely, helpful administrative support.

All stages completed to agreed dates. Careful and diligent installers and no mess.

Also care taken to ensure no damage to property and panel locations which are both effective and in keeping with the character of our home. 😃

Also good value.
