Heat pump installation
Reviews

Reviewers of Grant Store LTD often describe solar panel, battery and heating installations as smooth, with good communication and tidy work. Several reviewers mention being kept informed through the process, and some praise the politeness of installers and office staff. One reviewer reports a problem with a ventilation job, where a door was left not closing properly and wall holes were not sealed at first. Another reports panels fitted with screws coming through roof struts and an overflow pipe damaged, while a further reviewer says the office added unexpected charges and did not resolve them. A separate reviewer describes poor aftercare and being fobbed off when raising issues.
If it’s anything solar these are the ‘ go to ‘ guys nothing was too much. from the original contact to ronnie the surveyor to the installers the office staff and the accounts department they are all superb the install went without a hitch scaffolding was put up Friday the install was done Tuesday the install was done before 1pm that’s 16 panels an inverter and a battery The one thing I did notice that grant store actually care they actually want to help you get your system installed. The big box companies like edf ,boxt, octopus all give quotes that are drastically more for less kit ie smaller batteries and less panels and then don’t even call you back My system has been installed 3 months now and it’s amazing how much extra I am generating which is of course going back to the grid and making enough to cover standing charges as well You don’t have to look any further Thanks for all your help guys
Very impressed with Grant Store. From the very start the communication was top class. The survey was thorough so there could be no hidden extras. The price was very fair. We were listened to and the system was exactly what we wanted. There were some minor issues around the fitting etc (aren’t there always?) but the most important thing is that communication was excellent throughout. The issues were sorted in a timely fashion and we now have an excellent solar system which is working perfectly. Highly recommend.
The guys did an amazing job and the ease in dealing with the main office, could not have been easier. I highly recommend these guys
Excellent prices and service
As an existing owner of a small array of solar panels, I wanted to add a battery. Grant Store Ltd installed it in February 2026. It was installed with care and efficiency and there were two follow up visits by an inspector. It was easy to contact the company when I had a query. By choosing an appropriate tariff, my bills have reduced massively (45p in June!!) and I feel I have helped our poorly planet a little bit.
Totally satisfied with GSL This isn’t my first solar installation as my previous home was fitted with a system and that one was a poor experience. GSL on the other hand couldn’t have been more professional and I am extremely satisfied with the GSL Solar Installation process and end result. From the outset the quotation contact was straightforward, clear, concise and flexible. Follow up calls were helpful and not pushy. After deciding to go with GSL, the site survey visit was thorough and accommodating of my preferences. The surveyor was considerate and detailed, no doubt helping the installation which also went smoothly. The office support staff dealt with all the paper work and DNO application. Once the DNO approval was received, a date was set for the install and within a week the scaffolding was up, two days ahead of the system being installed. The fitting team installed the panels, inverter and battery in very poor weather conditions working hard until the job was completed, all within a day. The attention to detail and regulation compliance was particularly noticeable. A week after the install the office support followed up with a call and arranged for the scaffolding to be removed which was down a few days later. Communication throughout the process has been timely and helpful. Even a small change to the panel spec (540W instead to 535W) was followed up with new schematics delivered to my home in person. The paperwork pack (MSC documents, warranties, user guides etc) arrived when promised and I only await the DNO certificate for my export MPAN which is out of GSL hands. I thoroughly recommend GSL and would like to thank the whole team.
Excellent service. Turned up on time, installation very smooth and cleaned up after so I’m happy
Great job from start to finish,excellent work by the roofing team,electricians and follow up team.would definitely recommend Grant store for solar panel and battery installation.
Can't complain at all and I had 8 panels and no battery (not enough evening electricity demand to justify) fitted very efficiently and quickly as part of a council subsidised offer. All subcontractors (scaffolders, fitters and electricians very good) except it took the scaffolders a week to come back and take it away again. They came the same day as I complained to the firm.
We can highly recommend Grant Store to any one that requires any of their services. We had a new heat pump and new radiators installed throughout our house. Staff were excellent from start to finish, work staff were very courteous and respectful of our property, they kept all their work areas extremely clean and tidy, workmanship was extremely high. Had no issues during our installation, everything ran smoothly throughout the job.
Hi. I had a first time central heating system installed on Friday 23rd 2026 by grant store ltd.and the team that came to install it are out of this world [ Martin.garry.and kiaa.] Talk about professional it was all completed in a day.they were very clean.so very friendly.they certainly know there job.kept me informed to what they were doing. I give them 10 out of 10.if you want a team like these guys.then don't hesitate get in touch with g.s.l.again thanks guys.
Excellent installation. Great team! Kieran, Elliot and TJ on heating with Ash & Leon on Electrical installation. GSL did a brilliant job from design through to installation.
All teams came on time and done very satisfied with the work done
Central heating guys were brilliant ventilation guys poor took my doors off to cut a 10mm gap at the bottom living room door back on gap is more like 2 inches and the door doesn't close properly any more and the holes cut in the kitchen &bathroom walls weren't sealed properly someone had to come back last week to seal them as they had been chiseled out and left gaps around the rubber seals but they're done now but I will have to get my door taken off and re hung and a piece put back on the bottom or a new door cut and hung correctly
Just to say two really nice chaps Tom and Dave that came to my home today were clean and tidy in there work and weren't in a rush to listen or a quick chat before leaving. Nice one lads.
Experience Before Installation What made you decide to look into solar energy in the first place? It was a combination of factors. We like to think of ourselves as environmentally conscious, & it had been in our minds for a while, but it is a big expense, & we weren’t confident in our abilities to assess installers for quality. But with rising electricity prices & thinking of investing in a second electric car, it made sense. When we got a leaflet through the door from the council, that made the decision for us. We’d be able to get a good price and a company that had been thoroughly vetted. What challenges or concerns did you have about your energy costs before going solar? Rising electricity prices with two electric cars is obviously a major outlay. The solar panels have massively reduced our bill now. Choosing Us What made you choose our company for your solar installation? It’s really hard to know what you should be looking for as a solar-panel customer. We were hugely reassured by the council choosing Grant Store. We knew they would have thoroughly vetted the company they selected. How was your experience working with our team throughout the process? Grant Store has been brilliant at every stage: communicative & professional, explaining every step of the process clearly, not rushing anything & involving us in all the decisions. Installation Process How would you describe the installation process? Was it smooth and efficient? It was a very smooth & efficient process, with minimal disruption. Did our team meet your expectations in terms of communication, professionalism, and timelines? The whole team have been fantastic. It’s a daunting process, with lots of unfamiliar technology, but they took the time to help us understand everything, so we could work out exactly what we needed.
Thank you all . I've never been eligible for anything free/grant before in my life. All insulation and plastering was done diligently and clean. Communication was great too. Boiler conversion and electrical work went smoothly. Big thank you from me for everything . Phil and Tracey in Waterloo, Liverpool.
James was absolutely brilliant, the sign of a really good company is when they make a mistake, and then how they correct that mistake, grant store didn't get everything right ,along comes James and he never stopped till all was 100% right ,even communication with the office was so professional and very easy.from my solar panels, to my heating system grant store were simply brilliant. I would deafinatly recommend them if you want a good job doing well .the place to go for your heat pump ,heating and solar installations.
Kevin did an amazing job. He got the job done in roughly an hour. The netting looks good, he did repairs on the roof that we didn't realise were needed. Kevin gave us lods of useful information and we look forward to using his services in the future.
Brilliant experience with GSL. They are very responsive and easy to get hold of, whenever we had any issues they were able to sort it out quickly and without any fuss. Very happy with the work which was done to install the solar panels.
Workman don't give a crap. Shoddy work
Just had grantstore with an eco4 grant to install loft insulation, new combi boiler in different position and rad stats, controlled by a remote hive programmer. Only got Martin and garry's names ( plumbers ) sorry, but all the staff involved did an excellent job, the firm kept me informed about fitting dates and times, and they all turned up promptly. Everything was done neatly and no damage to decoration at all and cleaned up very well afterwards. All of the staff went out of their way to explain how everything works and kept their humour, despite my repeated questions!.The ideal boiler is working perfectly , I am very pleased with the whole experience . Definitely recommend. Colin
Very painful journey but got there in the end. Install date was moved, requested a call before installers came to make sure I was in but didn't get one. Full bill sent a few hours after issues were raised on a Friday evening with payment due the next day, Saturday (Never pay full until the full job is complete). Screws for the panels came through the side of the roof struts, wago clips used outside and told by installers it's fine, overflow pipe damaged, raised with isaac over email with photos who forgot some of the issues but after a lot of frustration eventually got him to fix things
We have just had a solar/battery installation completed by Grant Store Ltd through the Cheshire East & Warrington Solar Together scheme. Our overall experience has been extremely positive with excellent communications from the company by both emails and phone calls throughout the process. The survey was completed promptly and accurately and once approved by the Distribution Network Operator the installation was completed in around 4 weeks. The work was carried out over 2 separate days with both the roofing team and electrical installer being friendly and professional throughout. Frankly we were surprised by how quickly the work was completed and by how little disruption there was. The system has been in place for a week now and we are very pleased with its performance. We would have no hesitation in recommending Grant Store Ltd for this type of work based on our own experiences.
Thank you Dave Joyce for the survey last week. And for putting my mind at rest Tues 7th Jan 2025
Grant store installed a full central heating system and insulation for us back in February this year. Our home is so much warmer. Cant say we are saving on energy bills as the rates are sky high but so grateful to be much warmer than we have been! :) One star nocked off because the floor boards were left badly damaged after the heating was installed,…. we had to get them done up afterwards. Other than that, service from start to finish was brilliant! Thank you so much.
Dan H was really knowledgeable helpful good manners went above and beyond to explain everything nice guy
Great Service Provided and Good Communication, Very Pleased With New Combi Boiler.
Easy company to deal with good communication. All engineers friendly professional and clean & tidy
Deane and his team at Grant Store did a great job of retro fitting the Eco4 system to our home. Deane kept informed throughout and no question we had was too much trouble to answer. All the trades were great, respectful, tidy in their work, and very efficient. We added extra solar panels and a battery which we paid for, which Deane sourced and his team fitted for us. I would highly recommend them.
I was so happy with the hard work and politeness of Elliot and Nathan The new boiler is a dream come true. Thankyou so much
I'm very satisfied with them 100% from start to finish and the work men very good can't praise them enough thank you for a brilliant job
Was very pleased with all work i had done 5star service
All the fitters were wonderful, didn’t stop all day & were very helpful & olite
The team at GSL Ltd are very polite and professional. They kept me informed throughout the process of having my old Central heating system replaced. I am very happy with their work. Thankyou GSL for everything.
Did very good job of installing new boiler and radiators very professional everything was perfect very good trades men / installers polite and left no mess at all very satisfied with service from start to finish would recommend them to anyone also after sales service excellent highly recommend Grant store
Superb from start to finish in every department.l would recommend this company to anyone , highly recommended.
We recently had central heating fitted by GSL and we can't speak highly enough of the company. All the staff are polite and very professional. Excellent
AVOID find another installer This company was used as a sub contractor by another firm called Northern ECO installations,see my review on them as basically its the same review
Recently had my boiler upgraded to a newer more efficient model -due to the old one being on it's last legs. I couldn't be more happy with completed work, it was was very neat and tidy. The gas engineer was very concise and clear in explaining the basics of how to use the boiler i.e. adjusting the heat, pressure. I would definitely recommend Grant Store to anyone thinking of having their boiler upgraded.
Just had internal wall insulation fitted by Alex and Rick. Wonderful guys, tidy, friendly, excellent finish on the work and they went above and beyond for us. Highly recommend this company for its efficiency and top quality workers.
I had Alex & Simon at my house. Hands down, they are the best workmen EVER, by miles. They arrive on time, are polite, super clean & tidy in their work & cleaning up afterwards. Spectacularly good work was carried out by them both. They clearly take pride in the quality of work they do & their cleanliness in people’s homes, which is sadly lacking for most trade's people today who just don’t care how shoddy their work is or have no respect for people’s property. If only everyone worked to the very high standards of Alex & Simon. Big pats on the back & gold stars for them, it was a pleasure having them working in my home. 👏⭐️
Great job done by Rob and Danny there a credit to the company
Garry and Martin came to fit all my central heating this week every body has been absolutely brilliant care and respect all staff came to my property on time told me exactly wat was going to happen on the days they were hear had wall insulation by GSL and had Craig and Danny brilliant lads all have been so good thankyou
Abysmal customer service.
GSL is OK with installation. Those are done by professionals HOWEVER interacting with the office is a pain. Be aware of the extortionate addons to the quotes and unreasonable pricing for repairs/alterations. I was quoted £720 for effectively 1hr job and threatened with loss of warranty if I dare to use cheaper contractor for a fix... Job wasn't even that difficult...
What a great company to bring in to your home.arrived on time,was told what was to be done with the boiler. And after that the job was carried out with out fuss/mess. Acouple of great fitters, and very friendly office staff. All followed off by anice friendly inspection by a senior member of grant store. Will highly recommend this company for any work you need doing from the office staff upto the inspector who calls invited within 24hours. Many thanks.
Good lads who do the fitting but everyone be very careful with the contribution charges the office adds on. I paid £270 after originally being quoted £80 due to so called extra materials needed. When the lads finished and the extra materials were not used or needed I have contacted the office over 20 occasions now and Jordan and a female staff member just fob me off with promises of getting back to me.
The two surveyor's who came out were very professional and personal, we had a laugh about one being a Wigan warriors fan and we're Rhinos fans lol. Then Rob who came out to fit the boiler again very professional and personal, very tidy workmanship. Can't thank your company enough, new boiler fitted in less than a week and easy to deal with.
The fitters arrived spot on time and both worked hard informing us exactly what they were going to do,Rob+Paddy were very professional and were good reflection for grant store. boiler installation was great but let down by not having a electrition on same day
New boiler was fully installed and new hive smart meter within 10 days of initial phone call All workmen were professional, polite and friendly and worked to a high standard Company itself kept me fully informed of appointments/progress at all stages Great service No hesitation to recommend!
I have Alzheimer’s, so don’t like disruption . Grant store were brilliant . The men’s who arrived to fit , boiler , underfloor insulation , & hive , were fantastic . House left spotless . Thank you all for fantastic customer service . You are a credit to your profession . Regards & thanks . Paul .
Be very wary of this company before getting any work done, they are unreliable, dishonest and unprofessional and I would stay clear. I am extremely disappointed with the level of service received. Their promise you one thing and then end up doing something else. We have contacted them several times to resolve some issues, however they don’t appear bothered and seem to fob us off. Their customer after care is practically non-existent.
Sämsta jag varit med om. Mailat flertalet ggr och inget svar. Först när hot om ARN skickades hände något och trots det dröjde det ytterligare 2 veckor förens jag ens fick något i brevlådan. Totalt tog det över 6 veckor att erhålla något som de lovade skulle ta 1-3 dagar...bluff
I could not fault any of the workmen who came. They were there when they said, did the work efficiently and cleaned everywhere up after them. Wouldn't hesitate to recommend.
If your not on benefits don't bother calling them as you can't even pay them come and improve your home. Speachless! Unbelievable!
Had insulation and central heating fitted. Some work was poorly done still waiting to have floor boards sorted. Electrician came to fit the hive but would need to come back as needed two electricians. Came back but sent electrician and plumber so work again could not be completed. Not happy needs better communication of what is needed. Made a complaint but waiting of a reply and work still needs completing. Wasted my time of waiting in not happy at all.
I recognise good service when I receive it. Despite there being a fault in my Home EV Charger which was down to the manufacturer, Grant Store (GSL) never gave up at finding a resolution, even to the point of offering an alternative brand to suit my requirements. Communication was good from Jay, Neil and Steve. Steve came out at the earliest opportunity to re-check the installation. I don't expect e-mails to be answered outside of office-hours but GSL's customer service goes above and beyond. When the manufacturer eventually sent the part, Steve offered to fit on a Saturday. Another couple of days didn't make much difference to me and the charger was up and running on the Monday... after Storm Dennis had passed! I wholeheartedly recommend these guys to take care of your EV charging requirements. Mike
Fantastic service from first contact to fitting. Call centre staff very informative, 1 simple form to complete then sign online. 1 week later boiler fitted. Surveyor and gas fitters very professional and everything cleaned up afterwards. Thanks.
Hopefully get my new boiler in the next week
