Massive thankyou to Kenny hughes for the work hes completed, very well mannered and polite and really professional at his job..

Very polite and professional couldn’t explain enough and very helpful , many thanks to Dan Hartley

The company provided detailed documentation and were always happy to help when phoned. the sign up process was easy and the customisable initial proposal meant that we could tailor our system to how we wanted it. Our Renewables Coordinator, Zoe, was also very helpful and responsive to emails.

GSL are always prompt with their appointments and their staff are helpful, polite and experienced. Only had good experiences with the company, most recently for a post installation inspection carried out by David Joyce, who was polite, efficient and thorough, going out of his way to correct any minor adjustments. Thoroughly recommend.

David was very friendly and made sure everything was clear, understandable and thorough and was very understanding to the needs of the household. Household consists of people with social anxieties and made everyone feel comfortable for the entire duration of his visit.

Excellent all round service. Many thanks to John who inspected all the work which had been carried out, adjusted heating settings etc.and explained how everything worked.

Daniel Hartley is an understanding,thorough Surveyer! Talked me through the process of having the Heat Pump and the Boiler in situ. How it will help my health problems and disability issues. Thank you for your valuable advice

Joiner made a really good job closing and plastering hole and wall. Kenny Huges was wonderful and kept me informed every step of the process he cleaned afterwards and even washed the patio when plaster power got on it

Craftsman’s job expertly done by Simon Harrington

Kenny Hughes did an excellent job putting up a stud partition and door to box in my new system and making good part of the ceiling next to the roof hatch. Kenny was very polite, friendly and professional. Thank you

Excellent service at all stages in the installation, with frequent visits to check that everything is working correctly. All transfer documents and warranties have been received. Final visit today from Matt Cunningham, his second visit. Everything is working well. I am recommending GSL to my neighbours. Thank you very much.

The installation by Grant Store Ltd was completed many months after my initial application via Solar Together.
The survey and proposal was sorted out promptly and I was surprised to be told that 12 panels would fit on my roof rather than the 10 I had expected. I agreed to a 12 panel system fitted on 3 separate roof aspects. This included a 5kWh inverter, a 10kWh battery and emergency power supply to give us power in the event of mains failures (which I consider a growing risk due the Government energy policy). This was in November 2024.
The recommended system needed to be approved by the Distribution Network Operator (DNO) because of the size of the inverter.
I enquired about the status of the approval several times subsequently and in May 2025 I was informed that the DNO would approve the installation but limit the export to 2kW. It was subsequently suggested that if I would have a 3.7kW inverter I would not need approval from the DNO and that the installation could be started almost immediately with no limit on the export. I agreed to this change and paid my deposit, some 6 months after the original proposal.
As an aside here, I am baffled why this option was not offered in the first place as the 5kW inverter was overspecified for my installation and was the primary cause of the delay..
The installation was scheduled quickly, but the scaffolders arrived a day late and delayed the other trades. The panel installers turned up and on surveying the roof from the scaffold announced that they could not fit 12 panels and would only be able to fit 10 (the number I originally thought was the maximum!). So on two of the roof aspects they fitted four instead of 6 panels.
When they went to fit the final 6 panels they were unable to because the scaffolding didn’t extend far enough.
The electricians agreed to work whilst the four panels were being installed, fitted the inverter, battery and associated switchgear on an outside wall, did all the internal wiring and commissioned the 4 fitted panels, so we eventually had 40% of the planned output on the day we expected to have the full system.
I was given some handover documents by the electricians. I read through this and discovered that despite all our previous conversation, they had fitted a 5kW inverter, not the 3.7 one we had agreed!
Another week or so later the scaffolders turned up and fitted the extra platform in less than an hour. A few days after that the extra panels were fitted to the roof and the system was fully commissioned. I reminded them about the inverter and a few days later the electricians turned up again to swap inverters.
Almost immediately the invoice for the balance was emailed demanding effectively next day payment.
However the invoice was for the original 12 panel system with 5kW inverter!
They promptly corrected and replaced this and I paid up quickly, and then waited for the DNO to sign off the installation.’
A few days later I was contacted by Grant Store for my electricity meter number. Apparently the number taken during the survey was incorrect. To their credit the DNO reacted quickly this time and I am now in possession of system which actually works very well.
My electricity supplier OVO then processed the SEG payment in just over a day.
It has been a protracted exercise riddled with errors throughout. I should say that I found all the tradesmen (all sub-contractors to Grant Store}were hard working, very courteous and skilled despite being sent on wild goose chases that must have wasted their time.
All Grant Store’s telephone staff were extremely pleasant and helpful; I spoke to them a lot because I had to keep ringing to chase them up. All these hard-working people seem to have been let down by what, as a previous business owner, I would class as very poor planning and administration, with apparently no slack built into their schedules and the tradesmen having to accommodate this, I guess at their cost.
It is a shame that what should have been a quick and easy installation was dragged out for so long, because their prices through the Solar Together scheme and the recommendation from my local authority were the reason I took this route in the first place.

Had David Joyce (heating engineer) at our property today in Lancaster and very knowledgeable and friendly. All questions answered and very efficient. Top bloke 👍

Very helpful and really good job, very polite

we had Liam the Electrician today to complete the central heating fitting.
He was here early and completed the electrical work quickly and efficiently. He was very polite and friendly and certainly knew what he was doing!
He was a pleasure to have in our home and is a credit to himself and your company
(p.s. he explained about no thermostat on the radiator in the hall because the main thermostat is there....silly us!!!)

Mick and Linda Cook
It has been a pleasure to deal with you all. Thanks once again

Excellent service from the survey through to installation of a solar battery and inverter.

Matt Cunningham

The installation of my Solar Panels and Battery Storage with GSL went very smoothly. From initial survey to scaffolding removal the process and communication was excellent and any of my questions dealt with promptly. Many Thanks GSL!

Amazing job by Grant Store. Special thanks to Daniel the surveyor, Savannah, Kayleigh, Gemma and their team who worked so hard to get the paperwork right, Sam who coordinated the work, Ryan and Rhys for loft insulation and Saul Elliott and Ethan for the boiler and radiators. All were professional, friendly and efficient. Excellent service. Thank you
