Customers frequently praise the professional installation teams for being polite, efficient, and keeping work areas exceptionally clean and tidy. Consumers also note that the sales representatives are extremely informative, providing clear explanations, thorough answers to questions, and helpful guidance throughout the entire consultation process.

Great guys.

Great guys who worked most efficiently and provided running commentary at every step of the installation. The lead engineer provided a good explanation of the set up and, in particular, the app and laptop. Very pleased with the guys from LJM Solutions. They tidied up and left our place clean. Just looking forward to the scaffolding coming down.

The whole experience from first contact…

The whole experience from first contact to completion was excellent
The salesman was totally honest and very informative and wasn't in a rush to made us sign up offered express fitment which meant from signing up to install and fully working only took 3 weeks the scaffolding went up 4 days before the install date we were keep totally informed as to everything that would happen .
On the day of install the 3 guys arrived on time worked hard only stopping for a coffee did a excellent job very professionally explained every step cleaned up everywhere after themselves
Explained how it all works set up the tablet included and the app on my mobile all within 4 hours
System now been working 4 days and already proving what salesman claimed so would recommend spark to anyone
Just want to add a update on this review the scaffolding was taken down this morning that's only 6 days after the install if you take out the weekend that's only 4 days after install so other reviews complaining about time of removal it is not sparks fault the scaffolders are local sub contractors just wanted to add to my review that since install we have earnings of £82.64 from what we have sold back to British gas that's on top of cutting our grid usage by about 60% so it's best thing we ever did thnk you everyone at spark

Easy communication either over phone or email. Whatever been said by Spark Solar is done practically. Outstanding quality work by professionals. No room for any complaints. I'm satisfied 100% with the installation of solar through Spark. I was afraid initially because of bad experiences before on purchase and after sale customer service, but, as a layman, each time I contacted Spark with doubts, they listened and explained to me with great patience. 100% satisfied.

Excellent install and service, very professional

Really professional guys, got the job done in one day and did an excellent job together with explaining how the monitoring app worked. When I called about an issue with Myenergi app as a result of the install they did, they sent an engineer out the next day to get it all sorted. Wonderful service from sales to install completion. Highly recommended. Great aftersales coverage and peace of mind with the lifetime warranty.

Very happy with everything

Very happy with everything , friendly and helpful installers who did a very professional installation. They did everything possible to get the system up and running. Only issue we had was that the Wi-Fi signal wouldn’t connect with the system. This should perhaps have been checked by the sales team in advance.

polite & professional

The team of young men that visited were polite, professional and kept my house tidy. The whole experience was pleasant overall. I had some questions and I felt that these were all answered, those I have spoken to on the phone have been patient and informative. I have neighbors on my street interested in getting solar and I would happily recommend spark
