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.

All the best,
Spark

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.

Hello Paul,

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.

Your kind words mean a lot, and we’re so happy you’re enjoying your new system. Thank you for choosing Spark!

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

My house can now operate off grid, and huge savings in electricity consumption are likely.

From the visit of the salesman who went through everything in fine detail to all subsequent communications Spark have been fantastic. The 3 guys that came out to install the system were great and put a huge shift in to get it all done. They explained how it all works and tidied up after themselves.

Sales and installation experience

Both the sales and installation teams were very good and personable. They kept me well informed through the journey and the installation was completed tidily and with little fuss. Next is to get sorted with my energy provider and Spark will no doubt assist if any hiccups.

I would not recommend the company

The lady who picked up the phone earlier said Yes we can do a survey and give you a quote. But then, suddenly lost interest in providing a quote after they found out about my low annual usage and that someone had referred me. Told me the surveyors in my area are not available for a few weeks and don't know when they can come.

Hello Ujwala,

Thank you for bringing this to our attention, and we're genuinely sorry to hear about your experience.

What you’ve described is not the standard of service we aim to provide at Spark. Every enquiry should be treated with the same level of care and professionalism—regardless of your energy usage or how you found us. If there was any confusion or miscommunication, we take full responsibility and apologise for the way it made you feel.

We’d like the opportunity to put this right. If you’re still interested, please reach out to us directly and we’ll do everything we can to get a survey arranged at a time that works for you. Your interest in going solar is valued, and we appreciate your patience while we work to improve our customer experience.

Sincerely,
Spark
