Review summary

Created with AI, based on recent reviews

Considering 228 reviews, reviewers overwhelmingly had a great experience with this company. Customers frequently praise the professional installation teams for being polite, efficient, and keeping work areas exceptionally clean and tidy. Consumers also note that the sales representatives are extremely informative, providing clear explanations, thorough answers to questions, and helpful guidance throughout the entire consultation process.

Quick Install, Great Service

I’d had a few phone conversations with Spark and they sent someone over to talk us through and run figures on the reality of what we could save with Solar. The salesman was a bit pushy but we did agree to move forward. From then on the support we got from Spark was absolutely brilliant. Mark the sales guy was available for support via WhatsApp and the customer service reps for spark have all been great. I was kept in the loop and less than 3 weeks after our initial consultation our solar is already in, generating power and saving us money!

The contracted installers were great, friendly, helpful and efficient. Scaffolders did cause us a few slight issues but resolved them really quickly so all in all, no complaints!

No customer service

No part after the sale was complete went smoothly from delayed scaffolding, contractors not arriving or arriving late with no warning, we may have been unlucky with sub contractors absences & weather conditions also delayed but we didn't receive a single courtesy call informing us of any issues & we had to chase them for updates at every step. Once the job was completed they did manage to call quite rapidly to request we confirm completion so they can get their money. Now complete we're happy enough with the install but a 1 day job took 6 days, Spark had no answers to any queries as they dont appear to communicate with their sub-contractors or the customers until something goes wrong. They did accept the install got off to a bad start & offered £250 apology & said this very rarely happens to them but we find that hard to believe as nothing improved afterwards, they clearly send the job request to their sub contractors & then cross their fingers & hope all goes well.

Hello Kristian,

Thank you for taking the time to leave a review. We appreciate honest feedback — but for anyone reading this, there are some points that need clarifying to ensure the situation is accurately understood.

You’ve stated there was "no customer service”, yet you also mention that Spark:

Acknowledged the issues early on
Accepted responsibility for the delays
Handled your complaint directly
Offered £250 in goodwill compensation

That is, by definition, customer service — and more than many companies would do when part of the delay comes from factors outside their control, including subcontractor availability and severe weather conditions.

To be clear:

Spark did not ignore the problems
Spark did not deny the delays
Spark did not refuse support
Spark did not walk away once payment was requested

In fact, you received compensation before the job was signed off, which demonstrates that we were actively working with you to acknowledge and resolve the situation — not avoiding communication.

Subcontractors & Weather

Scaffolding delays and weather-related issues are unfortunately possible in construction work. While we fully accept there were communication gaps (and apologised for them), these delays do not reflect a lack of care — they reflect unpredictable operational challenges, which we addressed directly with you.

The Outcome

You also stated that:

“Now complete we’re happy enough with the install.”

So the installation quality met expectations. The issue was the schedule, which we rectified, apologised for, and compensated.

In Summary

It’s absolutely fair to say your experience didn’t run perfectly — and we acknowledged that. But suggesting Spark provided “no customer service” does not accurately reflect the steps we took:

We admitted the job did not start well
We investigated the delays
We maintained communication once the issue was raised
We compensated you
We ensured the installation was completed to standard

We stand by the apology and goodwill gesture offered, and we remain committed to improving the subcontractor communication process so situations like this are minimised.

If you'd like to discuss anything further, we are still here and happy to continue supporting you.

Sincerely,
Spark

Sparks solar have just completed my solar installation.
The 3 lads John, Arun and the other lad turned up about 08.00 on Monday morning. After me quickly asking them a question about how things stand with any failure to the roof.
They rang Sparks and I spoke to a gentleman, who answered the question and put my mind at rest.
Once sorted they cracked on with the installation.
The jib was completed by about 13.30. Everything fitted clean and tidy. The lads cleaned as they went
Aron set up the app and the wifi connection did the test. They had fitted 12 panels, batteries and charger in 6 hours and cleaned up.
I would definitely recommend Sparks solar.
Previous to having solar fitted. We spoke to Kiefer over a zoom call who explained everything from how the whole system worked and hopefully what we will save.
Once again thanks to all involved.

Hello Mark and Karen,

Thank you so much, for taking the time to leave such a detailed and thoughtful review.

We’re really pleased to hear that John, Arun, and the rest of the team made a good impression and that your questions were addressed straight away. It’s great to know that a quick call to the office helped put your mind at ease before the team cracked on with the installation, that reassurance is exactly what we aim to provide.

Completing a full install of panels, batteries, and a charger in around six hours is no small task, so it’s fantastic to hear how impressed you were with how efficiently, cleanly, and professionally the lads worked. Setting up the app, Wi-Fi connection, and testing everything before leaving is all part of making sure you’re confident and ready to go from day one.

We’re also glad to hear that your earlier Zoom call with Kiefer helped explain how the system works and what savings you can expect, that groundwork is so important in making the whole process smooth.

Thank you again for your recommendation and for choosing Spark Solar. We wish you many years of benefit from your new system, and if you ever need anything at all, we’re always here to help.

All the best,
Spark

Hello Thomas,

Thank you for your feedback. We’re sorry to hear that parts of your experience didn’t meet expectations, and we appreciate you taking the time to raise this.

We’re pleased that the roof tile issue was repaired promptly, protecting your property is extremely important to us. However, we do understand your frustration regarding the system handover and support afterwards.

Our standard process is for the installation team to explain the system and monitoring before leaving, and if further help is needed, our support team is always happy to assist. While emailing questions can sometimes be the quickest way to ensure nothing is missed and the right specialist responds, we understand that this may not have felt sufficient in your situation.

This isn’t the level of reassurance we want our customers to feel, and we’re sorry if you felt unsupported. We’d welcome the opportunity to talk you through the system properly and answer any outstanding questions directly. Please reach out again and we’ll make sure you get the help you need.

Thank you
Spark

WOW! FANTASTIC!

WOW! Just where do we begin?
With Steve Marriott who is simply FIRST CLASS at explaining, to two old wrinklies who had no real prior knowledge of what exactly we needed of an appropriate system to suit our home and circumstances, with clarity, patience and expertise. At no time did my husband and I feel rushed or pressurised into making any decisions which in this day and age is a rare occurence and very much appreciated. Steve's attention to detail we consider second to none.
Once our decision was made to go ahead, the Office Team of Alex, Jordan and Nicola kept us informed throughout and explanations to our many reflective questions handled in a timely, reassuring and professional manner. Nothing was ever too much trouble and we felt extremely valued. Again very much appreciated.
Now on to the install. All the scaffolders were extremely friendly, respectful and courteous, arriving on time and then working in horrendous conditions to complete their install in such a tidy fashion. Next up we had A.J., Joe and the team arrive to place the solar panels on to our slate roof with internal exposed beams. Again, care, attention to detail and professionalism were the names of the day and we were absoltely thrilled with the quality of install of the nineteen solar panels over two roofs of our home. The panels themselves fit seamlessly and are so discreet with no silver edges breaking up the roof line. Absolutely fabulous - far better than we ever imagined aesthetically.
And finally on to the wonderful electricians. Only two companies had been able to quote for the three phase meter at our now residential property, so the electrics were not straightforward. The delightful Sully, Louie and Billy who worked tirelessly again in horrendous conditions to link us up and install our nine batteries. Well into the evening all of the concerns my husband and I as 70 year olds, shared regarding the technical implications and monitoring disappeared when Sully and Louie patiently installed our apps for us, offered advice and clearly explained each and every detail with genuine customer care and empathy. Thank you so very much.
When a slight glitch occurred in operations Sully even came out to us on a Sunday morning to diagnose the issue. What more could you ever ask for? Finally, Callum visited all the way from Cornwall to Leicestershire to run a software update and all batteries were equalised and up and running.
We cannot praise Spark Solar enough and would highly recommend this company to anyone considering solar panels. The communication, attention to detail, craftsmanship, the care and pride in the work they offer a customer is ABSOLUTELY TOPS.
Thank you all very much indeed.

Wow — thank you so much Jeff and Sue for such an incredibly generous, heartfelt, and detailed review. It truly means the world to everyone at Spark to read this.

We’re absolutely delighted that Steve made such a strong first impression and helped guide you both with clarity, patience, and care. Your words about feeling unpressured and fully supported are exactly what we strive for, and we’ll be sure to share your kind praise with him — he’ll be over the moon to hear it.

It’s also wonderful to know that Alex, Jordan, and Nicola helped make the journey smooth and reassuring from the office side. Feeling valued and well looked after is at the heart of what we do, so your comments really mean a lot to the whole team.

Your recognition of the scaffolders, the roofing team (A.J., Joe and the lads), and especially the electricians — Sully, Louie and Billy — is just fantastic. Working in such challenging conditions and still delivering such a high-quality, discreet, and beautifully finished installation is a real credit to their professionalism and pride in their work.

Completing a complex three-phase setup with nine batteries is no small task, and we’re so pleased you felt fully supported and confident with everything by the end — especially with the apps and monitoring side.

Sully returning on a Sunday and Callum travelling the distance to ensure everything was absolutely spot-on perfectly sum up the commitment our team has to doing things properly, no matter what it takes.

Your words about our communication, craftsmanship, and genuine care have genuinely touched all of us. Thank you, truly, for trusting Spark Solar with your home and for recommending us so highly. It’s customers like you that make all the hard work worthwhile.

If you ever need anything at all in the future, we’re always here for you.

All the best,
The entire Spark Solar team

Terrible SCAM company won’t take no for an answer. Constantly ringing asking for someone who does not exist in our lives. Very rude staff and AI system. Just another company out to make money through hard sales and if they don’t get their own way they get abusive and swear at you.
They also seem to think it’s funny when you try speaking to a manager to report abusive harassment and hang up on you.
A very sad pathetic group of Scammers who can’t do a real job so they prey on the vulnerable.

Highly recommend

Overall my experience has been excellent!
From enquiring about getting a quote to now the system being installed has taken about 3 weeks.

Laurence who came to do the initial assessment and quote was very knowledgable and friendly. We weren't 100% committed to getting solar panels, but the information pack provided along with Laurence's answers to our questions convinced us it was the right decision to go ahead.

The guys fitting the system were efficient and got the system up and running super quickly which I was impressed by, as I was warned they may need to come back a second day to do their checks (because of it being winter and limited daylight hours).

I am leaving a 5 star review however, I was disappointed by the team doing the scaffolding as they were meant to arrive on Friday, and my partner had taken the day to be in for them. Unfortunately, after waiting most of the day and not receiving any notification from them that they were running late or unable to attend, I eventually rang up Spark customer care as the sun was starting to set, and only after them chasing up with the contractor did I get told they were delayed and unlikely to attend and would be here first thing Monday (installation day) before the installers. Monday arrived and the installers got here at 8am, but were sat doing not very much because the scaffolding guys didn't arrive until 10am.

Thid adds to why I am incredibly impressed by the installers considering they had the delay and also having to work in fairly miserable weather, and yet they still managed to get everything fitted and working before sundown.

I couldn't recommend Spark enough as everyone has been very friendly and shown great skill and expertise.

Hello Rhian,

Thank you so much for taking the time to share such a detailed and thoughtful review... it really means a lot to us and the whole team.

We’re delighted to hear that your overall experience has been excellent and that the entire process, from enquiry to installation, took just three weeks. It’s great to know Laurence made such a positive impression with his knowledge, friendliness, and clear explanations. Helping customers feel confident and well-informed is exactly what we aim for, so we’re thrilled that this helped you decide solar was the right choice.

Your kind words about the installation team are hugely appreciated. They’ll be pleased to know you were impressed by their efficiency and ability to get everything up and running in one day, despite winter daylight limitations and some fairly miserable weather. Their commitment really does shine through in situations like these.

Regarding the scaffolding delay, we completely understand your frustration. You’re absolutely right to expect clear communication, especially when someone has taken time out of their day to be home. We apologise that the contractor did not keep you updated, and while this aspect sits outside our direct team, it's still our responsibility to ensure the process feels seamless. We’re grateful you flagged it, and we’ll be addressing this with the scaffolding provider so it doesn't affect future customers.

Thank you again for the 5-star rating despite the setback — and for recognising how hard the installation team worked to overcome the delay. Your recommendation means a great deal to us.

If you ever need any help or support with your system going forward, we’re only a call away.

All the best,
