Excellent and highly recommended

The sales information was clear and helpful without oversell. The prompt follow up was great and gave us confidence on what was to be delivered. Communication is first class. The installation process was really good. The team were efficient and friendly and polite and kept us up to speed with what was going on and progress. Follow-up and after service timely and did what was needed.

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.

Hi David,

Apologies for the issue with WiFi signal, it is something we have since improved our process around capturing this information.

I’m pleased to hear the rest of the experience went so well.

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

There are better Options out there, DON'T use Spark!!

If I could give a negative, or a zero rating even, I would! From Day 1, there has been some issue or other, from the first installation team not being able to put the panels on, due to some issue with my roof, that disappeared when the second team arrived, the scaffolding was then left on my house for weeks after, giving anyone who wanted it (luckily no one did!) access to the rear of my property! Then after only 6 months or so, something went wrong with the equipment, an inverter malfunctioned, which, apparently, 'never happens', then 4 months or so after that, I noticed my tablet wasn't registering any energy being pumped back into the system from the solar panels, and I had to contact THEM, to find out what was going on, despite assurances from the sales guy about how it is always monitored and any issues will be spotted and dealt with! THEN, once I had chased THEM and had a couple of phone calls to ascertain that a technician would need to visit the house, an appointment was made for Wednesday the next week, so already over a month offline, so, a little urgent, you would think? I took a day off work and waited, I chased at 3 and was then told at 10 to 5 that the CONTRACTOR was running behind and wouldn't be able to make the appointment! So, as it stands, at this moment, I have really expensive paper weights on my roof, doing nothing! That for me was the pick axe that broke the camel's back, so I want these panels removed and a reputable company to come in and replace them, only to be told this is going to cost me EVEN MORE, if I want them to send a team around to remove them!! I don't think so, thank you very much. The experience with them has been unsatisfactory at every turn, I would implore you to keep looking and not use this company, you have been warned!!

Hi Dan, wow, you ARE very quick to respond to negative reviews, if only I got that sort of customer service from your operations department and not have to wait AGES for an unsatisfactory reply who ignore all questions I've asked!! (How's the investigation into why your contractor didn't turn up to my appointment going??) So, is EcoFlow going to remove your shoddy equipment? No? So, why do I need to speak to them? They can't fix how I feel about your useless company, so the only people I need to hear from are your accounts department to arrange my full refund and your team that needs to come and take this worthless kit away. If EcoFlow can do that, get them to call me after work, around 7, thanks

Hi Greg,

As we have advised on email, if you are unable to take the call from the manufacturer of your equipment - EcoFlow - we are unable to help further.

Great installation, waiting for scaffolding removal

The communication before the installation was great. The date for scaffolding section & panel installation agreed within a week.
Both installations completed on time. The installers were polite and diligent.
Spark agreed to have the scaffolding removed within 2 weeks, but this looks unlikely as I’ve not been given a removal date.
Ordinarily this wouldn’t be an issue, but as some of the scaffolding is on a neighbours land, it’s causing unnecessary frictions.
Maybe get a scaffolding removal date agreed before signing up if you have similar concerns.

Hi Charlie,

Im really pleased that the vast majority went well and you were happy overall!

Unfortunately our scaffolding contractor has had a few teams off due to illness and is running behind. We have contacted them again to stress the urgency of the situation.

We are sorry if our communication with you has not been up to standard in this regard and will learn from this experience to improve in future.

They arrived in good time and were polite and respectful and they got on with the job efficiently and demonstrated everything well once completed. They also left the front of the house as clear as it was when they arrived
