Outstanding customer service. Reference CALL 98684-F

Today I woke to not having any electric in my home.
I called national grid at 7.30am and spoke to a lovely, caring professional lady, unfortunately I did get her name.
The engineer arrived less than 2 hours later and fixed the problem within 5 minutes.
The serice was outstanding.
Thank you so much.

Kind regards
Linzey

If it breaks they dont fix it!

National Grid prioritises installations over support. They did a failed batery installation for me and after 2.5 months still nothing from them on fixing the issue. Please realise if you get a problem with their equipment they do not follow their 21 day SLA or Service Desk KPI's and just ignore you. I have no idea when they may get to it and am considering legal action

Battery installation

Shannon who sold us the batteries was very helpful and knew what he was talking about. What ever question we asked if he couldn’t answer it he would get back to us asap. We had to wait a while to get the batteries finally installed but once all done we started saving money straight away! The guys have installed them and made them look very neat against our wall.

NGSS great service

The system was well explained by Connor as was the details of the sale and installation.
As there was a delay with installation my solar panels were upgraded without cost.
The installation was extremely well done. NGSS kept me updated as to when the next step was to be taken.
The whole experience was very satisfying.
I have no trouble recommending NGSS to family and friends should they be thinking of getting a battery solar system.

No contact what so ever still waiting

Had someone come around and give a quote in December 2025.It is now March 2nd 2026.They have not contacted us with an installation date.We have been approved through bright for a no interest loan.No one has responded to our queries. Was only supposed to be 1 month after approval for installation still waiting on a call back. 3 full months of nothing.

Has been a nightmare dealing with this…

Has been a nightmare dealing with this company. Issues still needing to be resolved months after installation. Power company assessed work done by installers as defective. Lack of interoperability between solar panels and micro inverters and battery systems.

System Size: 18 KWPanel Purchased: Longi-LR5-54HTB-440M*Purchase Price: $32,000

It's just a Simple Process

I was looking around to expand my existing solar system and was having difficulty getting anyone to come and see me - everyone wanted to just look at google maps and send me a quote.
When Rod came and met with me to discuss options, he was only focused on finding out what I wanted, and how best to meet those needs. From then on it was an easy process to order the new system. NGSS took care of all the paperwork with my electricity provider and kept me in the loop when that took a little more time than expected. Once approved, the service team contacted me, and we agreed on an installation date. John and his team were bang on time and worked till after dark to get my system installed. They came back the next day to check and commission the system - and I was on my way.
Overall, an exceeding simple process, and great service from a group of people that knew what they were doing. I can't recommend these guys highly enough. I've said this before, but you do get what you pay for - you won't go wrong with NGSS.
