From the initial consultation to the…final installation telephone call

From the initial consultation to the post installation tele[phone courtesy call, SPARK have done everything that they said they would. They dealt with their issue to my convenience.
They are extremely informative, keep referring back to you to keep you completely informed. Service staff and the installation staff were excellent. Special thanks to Steve the rep, the 3 guys who installed (apologies I forgot the names) and Alex (Junior Manager).Can't recommend you highly enough.

Hello Emyr,

Thank you so much for taking the time to leave such a detailed and thoughtful review — we really appreciate it.

We’re delighted to hear that everything went smoothly from the very first consultation through to the post-installation courtesy call.

Doing what we say we will, and keeping customers fully informed at every step, is exactly what we aim for. We’re also glad we could resolve the issue at a time that worked best for you!

We’ll make sure your thanks are passed on to Steve, Alex, and the installation team — they’ll be thrilled to hear your feedback. Your recommendation means a lot to all of us at Spark.

Thank you again for choosing us and for trusting us with your installation. If you ever need anything in the future, we’re only a phone call away.

All the best,
Spark

A company with integrity!

I was called by Spark based on an old inquiry I had made a while ago but at the time decided it wasn't the right time. Getting solar panels has always been something I've wondered about and whether I was missing out by not getting them. In any case, it turned out that my bills are that low due to my living circumstances that it just wasn't worth me getting them. The agents at Spark were very upfront with me about this and didn't try to sell me solar panels they didn't feel I needed. I was very impressed by this level of integrity and have vowed to recommend them to anyone interested in getting solar panels. They are also the first company I will contact if I'm ever in a situation where solar panels would be handy. All around I was very impressed with their service and their honesty!

Hello Graham,

Thank you so much for taking the time to share this — what a fantastic review!

We’re genuinely pleased to hear that you felt the conversation with Spark was honest and transparent. Not every home or circumstance is suitable for solar, and we believe it’s just as important to say when it’s not the right investment as it is to help customers who would benefit. Saving people from unnecessary costs is part of doing the job properly.

Your comments about our integrity mean a lot to the whole team. We’d far rather build trust than push a sale, and it’s great to know that came across in your experience.

Thank you for the recommendation — and if your circumstances change in the future, we’d be more than happy to help you explore solar again.

All the best,
Spark

Slick and professional with no hard sell

We had Ben B come and see our house in Exeter. He did a great job of explaining the tech and talking us through everything.

As and when we changed plans he called head office and they updated the quote and drawings immediately.

He called back a week later to see what we were thinking and answer any questions. I said I needed another week or 2 to go over the figures to which he said fine. No hard sell or any pressure.

So far it's been a great experience.

Thank you so much for your thoughtful feedback! We’re really glad to hear that your experience with Ben and the team has been such a positive one so far. It’s great to know he took the time to explain everything clearly, kept the process flexible, and made updates quickly to match your plans.

We’re especially pleased that you appreciated the no-pressure approach — that’s exactly how we believe solar should be discussed: informative, transparent, and at your pace.

We’ll be sure to pass your kind words on to Ben and the office team — they’ll be delighted to hear your feedback.

I’m really sorry to hear that you had a negative interaction. That’s definitely not the experience we want anyone to have. We take feedback like this seriously and would like to look into what happened so we can address it properly.

We’ve reviewed the communication in question and can confirm that our representative was merely following up with you to confirm customer interest and prevent unnecessary calls, closing your quotation if you were no longer interested. We’re sorry if the SMS interaction came across differently — that was never the intention.

Our team always aims to communicate respectfully and efficiently, and we appreciate the opportunity to clarify this.

Sincerely,
Spark

Incredible service - cannot fault a thing!

From enquiry, to quote to installation I cannot fault a single thing!
Everyone I spoke to was friendly, polite and not pushy at all. On the day of installation the team were so efficient and left everything so tidy. Really really pleased with the work.
Thank you so much!

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!

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!
