sold my data

Someone came to our house so we could get a quote, we decided it wasn't what we wanted to do at this time. The sales man was pushy but whatever it is what it is. Since, I have had calls from many different people, someone warning me i have damp in my roof and they need to come and check it (not true). It's just ridiculous how they didn't make a sale and now i have different companies calling me referencing my recent solar quotation. Just steer clear if you want to protect your privacy.

Problems month after install

Over a month after installation, scaffolding still erected. Called Spark to let them know, they were completely unaware. They told me it would be sorted as soon as possible - we are now 10 days later and still the scaffolding is up and no contact from Spark. Due to multiple issues with our install, we were offered £250 compensation. After our previous review (11th December), Spark replied saying that compensation had been paid before completion of job - we are still awaiting that payment and yet again no contact from Spark.

Looking at other reviews, it seems we have been very unfortunate with the service we have received, however, would just like some acknowledgement of the poor service we have received, rather than being dismissed. Don't like making complaints or writing reviews like this, but it seems there is no other way for us to be heard.

Hi Rachel,

We are sorry that you had a rare poor experience. We were let down by our scaffolding subcontractors and have since removed them as a suppliers.

I am aware that the team have since resolved the issue and we will always be on hand to support in the future. We very rarely get things wrong but we did here and it is unfortunate that it happened to you.

I hope you have nothing but positive experiences with your system and any support we need to provide in the future.

Rated 5 out of 5 stars

Professional and efficient service throughout.

The initial presentation was very comprehensive and included a walk and talk through of the system and how it would be installed. After some research and having agreed a package, the install date was quickly booked. Scaffolding arrived earlier than expected and the team were professional. Installers turned up on time having messaged the day before, and kept me informed of progress throughout the installation. There were some slight differences in the installation to how it had been described on the original meeting, due to isolation switches but the Spark kit is as described and it has all been done neatly. The installer hadn't seen the tablet before so we were both learning, the only issue is it will use it's battery in an hour or so and requires to be permanently plugged in. It may need some settings changing but it's new to me, and I can't see anything obvious. Panels are very neat, really happy with how they look. Time will tell how efficient and worthwhile it all is, hard to judge in the depth of UK winter but they start producing as soon as the Sun starts to come up. Scaffolding is due down today, one day after completing the necessary paperwork with Spark following installation.

Hello C Kirman,

Thank you for taking the time to leave such a detailed and balanced review, we really appreciate it!

We’re pleased to hear that the initial presentation was thorough and helped you clearly understand both the system and the installation process, and that once you were happy to proceed, everything moved quickly. It’s great to know the scaffolding and installation teams were professional, punctual, and kept you informed throughout. That communication is something we place a lot of importance on.

Thank you as well for your understanding around the small differences during installation relating to the isolation switches. We’re glad to hear the Spark equipment itself met expectations and that everything was completed neatly. We also appreciate your comments regarding the tablet. As newer hardware is introduced, there can be a short learning curve, and we’re always happy to help with settings or advice if needed. If you’d like us to review the tablet setup or battery usage with you, just let us know.

We’re delighted you’re happy with how the panels look and that you’re already seeing generation, even during the darker winter months. As the days get longer, you should start to see even stronger performance!

Thank you again for your thoughtful feedback and for choosing us. If you need any support at all as you get used to the system, we’re always here to help.

All the best,
Spark

We recently had a solar panel and battery system installed at our home by SPARK, and we couldn’t be happier with the whole experience.

From the initial consultation to the final installation, the team was professional, knowledgeable, and very easy to deal with. They explained everything clearly, answered all our questions patiently, and helped us choose the right system for our household needs.

The installation team arrived on time, worked efficiently, and kept everything tidy throughout the process. The quality of workmanship was excellent, and they made sure everything was fully tested and properly set up before leaving. They also took the time to show us how to use and monitor the system.

Since the installation, the system has been working perfectly, and we’re already seeing the benefits in terms of energy usage and cost savings. Overall, SPARK provided an excellent service with great attention to detail.

Highly recommended to anyone considering solar panels and battery installation.

An excellent exhibition of teamwork

The team who installed the panels were punctual, polite, tidy and efficient. (This also applies to the team of sub-contractors who installed and removed the scaffolding). They all knew exactly what they were doing and worked together as an experienced team.

Great service from sales to install

The team were great as a whole. Mark did a great job during the sales process and did not try and oversell the product at all, which we greatly appreciated and even happily told us to look over everything to if we needed more time. On top of that the install team were fantastic. Mac, maculaley and Ollie were great and when things didn't go to plan (due to our WiFi setup) they happily came back and continued to try and assist us as much as possible without making us feel crap about it.

Would 100% recommend

Hello Victoria,

Thank you so much for taking the time to share such a thoughtful review!

We’re really pleased to hear that Mark made the sales process comfortable and pressure-free — giving customers the time and space to make the right decision is something we truly believe in. It’s great to know that approach was appreciated.

We’re also delighted to hear such positive feedback about the installation team. Mac, Macaulay, and Ollie will be thrilled to know their patience and willingness to come back and help — especially when things didn’t go perfectly due to the WiFi setup — made a difference. Making sure you felt supported, not uncomfortable, is exactly how we want our customers to feel.

Your recommendation means a great deal to all of us. Thanks again for choosing Spark!
