We purchased our Solar PV and battery installation from FDG after being very impressed with their salesman Steve F, who was friendly, knowledgeable, fair and honest, and whose level of service was head and shoulders above the other companies who quoted us. We felt that their offering was good value in the market so chose to go with them. Installation was duly arranged, and everything went downhill from there... pinpointed pretty much to the moment we handed the money over. FDG had subcontracted the work out, so we found that engineers did not turn up when they should have done, and when they did turn up some of the critical parts were missing so we had to wait around a week for them to come back to finish the work and activate the system. The standard of workmanship was good, but they missed off all the safety labels for the system, and we got no demonstration of the product or any information on how to get the best out of it. After a lot of chasing FDG sent their own electrician out to rectify the lack of safety labels. The app for us to analyse our usage didn't work, which turned out to be because the inverter was running on old firmware and needed updating, which he also did. (We understand from FDG that they have since stopped using subcontractors). Regulatory paperwork was either missing or very late, and we had to keep chasing for months for some of this, including the paperwork to register our system with the network operator. FDG kept insisting that we didn't need it, but our utility providers insisted we did. We eventually got it after several months after lots of chasing. Meanwhile the director mistook us for another customer and started emailing us chasing payments that we didn't owe. We have since had some errors pop up on our system and have emailed the company a number of times to get some advice, but we have never received a response. We've given them a very generous three stars because we're overall pleased with our system and were very impressed with Steve F. But their aftersales service leaves a lot to be desired and we felt this let them down.
