A great experience from start to finish.

Good communication from the head office all the way through. The installation was very quick and the installers were a great bunch of guys. They left the place very tidy. The tablet Spark provide shows how much energy the panels are providing and very pleased with the results so far.

Recently had Solar installed by Sparks

Recently had Solar installed by Sparks.
The salesman Jonathan came out at the agreed time and went through everything in detail. Was very professional and polite.
We had our date booked in, however on the day of installation their van broke down and they had to reschedule. This was done very quickly and they came out two days later due to it being the weekend.
On the day of installation they arrived on time and got straight to work. They were friendly and hardworking. They would sing as they worked, sadly not the best singers but the song choice was good.
There was a part missing from the order so they were unable to complete all of the work on that day and another team came out a few days later and fitted the part with no issues.
I had to do a little bit of chasing up to find out what time the second team would be coming out to fit the missing part. They came out around 19:30, I must admit I didn’t think they would be coming out that late. But they did and I was very appreciative of them coming out to finish the work. The electrician called Tony took the time to run through the app which was a big help.
Every is installed and working as it should.
Very pleased that I chose Spark for my Solar Panels.

Hi Louis,

Really appreciate you taking the time to write such a detailed review, it really helps other customers understand the reality of choosing us!

Obviously things do occasionally go wrong but it sounds like both occasions were sorted quickly and with minimum disruption.

Great friendly team

Great friendly team, answered all our questions using the newest and best products and making things work for us. Entire thing from start to finish took less than 3 weeks! Amazing. Hani was lovely on the initial consultation, Alex in the office was very prompt every time and sped everything along well. The scaffolders and install team were also incredibly quick, professional and friendly, thanks to Mick Riley and Evan on the install team :)

Exceptional team at Spark

Really pleased with service we have received from Spark. Through the whole process of installing solar panels from initial survey through to ordering,installation and set up the whole Spark team have been unfailingly polite, helpful and extremely patient.
It is so refreshing to actually speak to a real person who listens to your questions and explains in layman’s terms how to resolve the problem. Special mention to Maria who stayed on after her official hours to help me update the app. Great teamwork from Spark.

Couldn't be better

If i could I would give 6 or more stars for the service received from Spark. From the initial phonecall right through to the final removal of the scaffolding, they could not have been better. I've rarely if ever come across such a friendly and efficient group of people. The guys who put up the scaffolding and the lads who installed the panels worked in the heatwave with temperatures up to nearly 30c. No complaints, just hard work. Dealings with the office have always been excellent too. Great company.

Hi Alan,

Would love to take you up on the 6 stars! Thanks for leaving such a detailed review, its great to see that we're delivering to the level we set out and its really useful for other customers to judge how we operate.

We'll take the 30c over doing it in snow any day!

Harassing

Being harassed daily from lots of 0330 and mobile numbers and text and email after repeated being promised they would remove my details. Today I’ve been hung up on when I explain the breach to them and told i will be listed as a vulnerable customer as I couldn’t remember the correct company name.these people are awful.

Hi Caroline,

I have checked our system and you were removed and marked as 'Do Not Call' the first time we spoke to you and you made the request.

Subsequently, our system has been called by you a further 4 times. We cannot block you from calling us.

Cheers,

Very professional the install was done in a day and they were very diligent in their work. They double and triple checked their work before leaving especially when the system kept saying there was a fault when in fact there wasn’t one. Highly recommend

I can’t recommend Spark highly enough

I can’t recommend Spark highly enough. The service was excellent from start to finish. Although there were some issues with a third-party scaffolding company and a delay in our install of our panels, the team handled everything exceptionally well. Their response was second to none—they were consistently responsive, proactive, and kept us well informed throughout. I really appreciated their commitment to resolving any problems quickly and efficiently
