I’m very pleased with Spark for the professional installation

I’m very pleased with the work done by Spark on my home solar installation. They used the latest technology and showed great professionalism throughout the project. The job was completed quickly and tidily, and the results exceeded my expectations. I can highly recommend Spark to anyone looking for a reliable and efficient solar installation company.

Unprofessional, focused selling.

The initial call was misleading, offering solar panels for £100 upfront and then £49 a month. This may be possible for someone but was made out as if that was what I would be paying. Any questions I tried to ask were answered with the fact that the caller was only able to set up an appointment with a surveyor, but the surveyor would be able to answer all my questions. I had some concerns about my energy bill so set up an appointment. I specified that the person coming should have his ID ready, I suffered with anxiety and was careful who I let in. I was told I would receive an email with the persons name before the appointment. I didn’t get an email and the only ID was his drivers licence and a company fleece. He wasn’t a surveyor, he was a salesperson. He went through everything very thoroughly, walked round the outside of the house checking the roof, stuck his head in the loft and expressed concern over the type of insulation, butthen said it would be ok. I was told if I signed up that day I would pay £2000 less because they could guarantee the price on stock in the warehouse. However, if I took the 3 month option, ‘today’s price couldn’t be held. I said I couldn’t pay anything at present. Before I knew it I was signed up for panels, batteries and an inverter AND a 15 year loan. I asked for a couple of days to think about it before I signed but was told I would lose the price. If I signed up I always had my 14 days cooling off period.
2 days later I had a phone call asking if the contractors could come and do a check , they came 2 days after. Again, no ID, even worse, completely different fleeces, neither of them Sparkshome, and a plain white van.
I did use my rights under the cooling off period, on both the loan and the Solar setup. It all felt rushed. I felt my requests had been ignored. Everyone was very pleasant, no one was obviously pushy, although I was told the’surveyorl’ would be here an hour and he was here nearly 3. Mark, the salesman, said I could have a family member here if I wanted.
When I cancelled I said it was because of the length of the loan, which is true. I really didn’t want to have a loan, let alone for that long, but Ialso felt I had been hurried into making a decision and wasn’t really happy with the company’s lackadaisical attitude.

Dear Kay,

Thank you for taking the time to share your experience — we’re genuinely sorry to hear that your interaction with Spark left you feeling uncomfortable and rushed. We take feedback like this seriously, and while we respect your decision to cancel, we’d like to provide some context and clarification for anyone reading your review.

Firstly, Spark does not engage in misleading or high-pressure sales tactics. Our representatives are trained to provide accurate information about the range of finance options available — including examples of what customers might pay depending on system size, energy usage, and credit profile. The “£100 upfront and £49 per month” figure mentioned in your initial call would have been a general illustration, not a guaranteed quote.

Secondly, we’re sorry to hear that you did not see the appointment confirmation email with the representative’s name before the visit. Our records show that the email was successfully sent and that you've opened other communications from us, though it’s possible it may have been overlooked among other messages. Providing this information is part of our standard procedure, as we always want customers to feel fully informed about who will be attending their property. The individual who visited was one of our trained energy consultants (sometimes referred to as a surveyor), responsible for assessing your property and discussing suitable system options — not an installer.

We also want to stress that our policy allows every customer a full 14-day cooling-off period, exactly as you used, with no penalties or pressure to proceed. While our representatives do share time-sensitive offers based on stock or manufacturer pricing, Spark customers should never feel rushed into signing as our other customers can validate.

Regarding the follow-up visit, we understand your concern about the team who attended. An appointment had been arranged by us at your request and accepted by you, the visit was carried out by Spark. While vehicles may not always carry Spark branding, any team arriving at a confirmed appointment is working on our behalf and follows our professional standards and procedures.

We appreciate that you found everyone polite and professional, and we’re truly sorry that the overall experience didn’t meet your expectations. Transparency and trust are extremely important to us, and we’ll be reviewing this case carefully to ensure future customers feel fully informed and comfortable at every step.

Regards,
Spark

It all just happened like clockwork

It all just happened like clockwork once I had approved the quotation. No fuss, well communicated and finished in 6 hours or so. And that was in the rain too. Even the scaffolding will remain up for another week to ensure there are no leaks.

Hello Stephen,

Thank you for sharing your experience! We're so pleased to hear that everything ran like clockwork from approval to completion. Clear communication and a smooth, hassle-free process are exactly what we aim for, so it’s great to know that came through.

Finishing the job in just six hours — and in the rain, no less — is a testament to the team’s hard work and professionalism. Leaving the scaffolding up a little longer is part of our quality assurance, just to make sure everything stays watertight and perfect.

We really appreciate your feedback — thanks for choosing us!

All the best,
Spark

I had an excellent experience with Spark Solar. The whole team was amazing – very friendly, polite, and professional from start to finish. The installation was completed quickly and everything was done very cleanly and neatly.
What impressed me most was that everything we agreed on in the plan and the offer was delivered exactly as promised after signing the contract. True professionals who clearly care about their work and their customers.
I highly recommend Spark Solar to anyone looking for a smooth, professional, and stress-free solar installation.

Smooth Installation and Outstanding Support

I recently had solar panels and a battery installed by Spark, and I’m very happy with the process. Everything was well-organised, transparent, and carried out exactly as planned.

Mark from Sales was patient and clear in explaining the benefits versus costs, which gave us confidence in our decision. The team was professional, responsive, and quick to address any concerns.

The scaffolding and installation teams did a fantastic job. The work was clean, neat, and efficient, making the whole process hassle-free.

Special thanks to Tom from the Operations Department, who was incredibly patient, supportive, and went above and beyond to ensure I was happy with the installation.

Overall, Spark delivered excellent service. Highly recommended!

Honesty and integrity

Speaking to Abdul was an experience of honesty that I have not heard for many years if ever. We were interested in the possibility of having solar panels. Having explained myself and my wife's age and are very low electricity consumption Abdul without hesitation made us aware that we are more than likely not to get a return in less than 20 years on our investment and of course he was right .That being i would highly recommend your company for there honesty and integrity. And would not hesitate recommending you and s finally we feel that Abdul is an absolute credit too your company

Hello Nina,

Thank you so much for sharing your experience. It’s wonderful to hear that Abdul’s honesty and integrity stood out to you — he will be so pleased to know the positive impact he made. We believe it’s just as important to advise when solar may *not* be the right option, as it is to guide people when it is.

Your recognition of Abdul as a credit to Spark means a lot, and we’re proud to have him on our team. Thank you also for your kind recommendation, even if solar wasn’t the right fit for you, your trust in our approach is invaluable.

We wish you all the best, and please know we’re always here if you ever have questions in the future.

Excellent service

From start to finish, plenty of communication. No hard sell.

I was given no obligation quote with a call back on an agreed date, answered my questions before proceeding with the booking.

Onky a short wait for the installation date, the scaffolding came a few days before build. When the team came for installation, they were done in the day.

I had 14 panels on front and back, a battery and inverter fitted. Power was only turned off in my house for an hour.

The team were happy in their work, very productive, and happy to answer questions throughout.

After sales calls have also been received to check on our system and answer any questions we have, and I know if I call Spark,I will get a helpful, knowledgeable person on the other end of the phone.

Thank you for such a detailed and thoughtful review! We’re delighted to hear that the whole process was smooth and well-communicated from the very start. No hard sell, clear answers to your questions, and a no-obligation quote are exactly the kind of experience we want every customer to have!

It’s great to know that installation was arranged quickly, with scaffolding set up in advance and everything completed in just a day. Having 14 panels, a battery, and inverter fitted with only an hour’s power downtime is no small job, so we’re glad the team’s efficiency and professionalism stood out.

We’re also pleased that you’ve found our aftercare to be just as supportive, with follow-up calls and the reassurance that knowledgeable help is only ever a phone call away.

I have almost daily calls from an automated service using my name and pretending to be a person. The automated service says it is Solar Discounts and asks a series of questions, waits for any response, then after the three questions puts me through to Spark Solar. The lady that took the call at Spark Solar new my full name and address when I was put through and said she knew nothing about Solar Discounts or this automated service. Solar Discounts use a different number each time, so although I block the number the calls keep coming through. When they called today they called on 0333 053 6115. I don't even want solar panels.

Hello Matt,

Thank you for raising this — and we’re really sorry to hear about the nuisance calls you’ve been receiving.

To be clear: Spark does not use any third-party marketing companies like “Solar Discounts.” Unfortunately, we’re aware that some lead generation companies make unsolicited calls and then pass people through to legitimate installers without their consent. This can cause confusion and frustration, especially if you’re not looking for solar in the first place.

We understand how frustrating this must be, especially as you’ve no interest in solar panels. Please be assured these calls are not from Spark directly, and we do not condone such practices.

Sincerely,
Spark
