Very approachable and honest sales team

I contacted the Spark sales team today and spoke with Adam Charles with an initial enquiry about a solar package for my house. I wanted to bottom out a few things with him before we got too far into making any arrangemements for a visit and he was very open and helpful in doing this. Due to his obvious knowledge and diligent questions back to me he quickly established that at this point in time, solar panels would not help me make any savings particularly as a long term project given how relatively low my current energy costs are. To be honest I was impressed with his honesty and it made such a change to speak to someone with integrity these days! My source of energy is reliant on a form of solid fuel that although will never run out it may well find itself outlawed in the next few years and I will have to consider other sources. At that point and due to the service I received today Spark will almost certainly be first on my list to call again. So a valued phone call that today might not have won Spark my custom may well do so in the future and I hope Adam is still around to talk to then. The company gets a thumbs up from me so far!

Hello Rich,

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

We’re delighted to hear that your conversation with Adam was helpful. His approach is exactly what we believe in at Spark: honest advice, no pressure, and clear guidance based on what’s genuinely best for each customer. If solar wouldn’t give you meaningful savings right now, it’s important you hear that upfront — and we’re glad you appreciated the integrity behind that.

Your situation with solid fuel is a great example of why every home requires a tailored assessment, and should things change in the future, we’d be more than happy to re-evaluate your options. It’s wonderful to hear that, when the time comes, Spark will be at the top of your list.

We’ll be sure to pass your feedback on to Adam — he’ll be thrilled to know the positive impact he made.

Thanks again for the thumbs up — we’re here whenever you need us.

The sales pitch was excellent and we…

The sales pitch was excellent and we paid the £3000+ deposit, but on reflection we found the price too high for our budget.
We aksked for the deposit to be returned, but are still waiting, it sits in our account waiting to be released by Spark. Not a real issue except I cancelled the agreement on 3 November and we are still waiting for our funds to be repayed. Come on Spark accounts, return our deposit, please.

It is 12 Nov and the deposit still has not been returned to my account, and sits there pending!!!
Sadly, Spark accept payment on the same day, but take over 10 days to return deposits, a common method to invest clients funds for a week or more.
Will i get interest on my payment???

Dear Patrick,

Thanks for getting in touch, and we're sorry for the frustration here.

To confirm: your deposit refund was processed on our side via Stripe on 3 Nov 2025, 14:40.

Refunds issued to the original payment method typically take 7–10 business days to appear on your statement (card issuers can sometimes take a little longer to post them). Since you cancelled on 3 November, you should see the funds shortly, within that normal window.

A couple of helpful next steps:

If the refund hasn’t shown after 10 business days, we can provide the Acquirer Reference Number (ARN) so your bank can trace it quickly.

You can also check with your card issuer for pending credits, as they sometimes show before they’re fully posted.

We don’t hold the funds after initiating the refund; at this stage it’s with Stripe and your card issuer’s processing timelines.

Should you have any further questions, feel free to contact us direct.

Sincerely,
Spark

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.

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.

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
