Disappointing customer service
Customer Service
Contacted FDG Group last week requesting a review of my system due to inadequacy in heating and energy usage. Was told by the lady on the phone I would get a visit from an engineer on Wednesday 7th July, on the day waited between 8am-3pm, nobody attended. Rang the company asking them what was happening, they were unable to say. They couldn't contact the engineer himself and left me in limbo with what to do with the heating system they installed. This situation has happened previously with this company when they didn't communicate with me during the installation and after the installation of my heating system. I was left in confusion as to what to do on some issues regarding the installation and working of the system. It took getting on nearly 6-8 weeks on understanding my heat pump before anybody came eventually to see me. Several requests I had with them which I asked them to follow through because I was on holiday during the installation did not come to fruition and I completely felt let down by the company. I will now reserve the right to complain at a later date if this issue is not resolved and baring in mind that the director came back to me shortly after installation with a sharp tone of voice asking why I'd given him below score on his rating.

Triumph through Adversity
Customer Service
The work itself was carried out efficiently and thoroughly. The Team that were sent were brilliant. Despite the fact that it seemed to rain continuously, the team worked well and were polite, considerate and minimised the chaos. The two that I would like to draw your attention to is specifically Mitch and Jason. They were both excellent. Nothing was too much for them and they were here late making sure that everything was sorted at the end of each day. A huge thanks to both of them as well as the rest of the team. They system is working well and we are delighted with the end product. One thing I would like to mention is that on day one the team didn't have the products on site to start the job. The radiators weren't delivered to us until day two, which was a shame, as this delayed the start and meant that a 5 day job became 7. Thanks lads. I am now hoping the back up to get the system registered and RHI claim sorted is carried out as efficiently as the job itself.

Renewable Energy provider and maintenance solution
Customer Service
FDG Nottingham is a company that has a family mentality. That means once they have installed the Air Source Heat Pump, they will continue to offer customer support. There was an issue with the ASHP (which is also covered by warranties by Vaillant and HIES) not working in the icy weather. The customer helplines were always open and we were never left without hot water at all, and heating once we called them. The issue we had, prompted an early annual service during which they checked all components of the ASHP and their workings. The entire ASHP was cleaned; mechanical components checked, cleaned and operation checked; levels checked; viz pressures and glycol levels; reservoir drained; electrical connections were checked and the operation in full. Checks on all system controls and operations were made. Adjustments to the control were made to suit us. We would definitely use this company again as they are extremely knowledgeable about renewable energy, efficient and approachable. The company has implemented a reliable customer aftercare call centre. What they could improve on is a more systematic approach to dealing with customers, with text or email 'paperwork' to follow up in response to every reported issue. FDG have now introduced a monthly payment maintenance scheme for ASHPs. This includes an annual service and the rectifying of any issues throughout the year.

Appalling work & customer service
Customer Service
My partner has dealt with FDG on this install and has been very patient and far too understanding with them, so I'm leaving an honest review. *Delayed install without notice - cost us in extra rent not planned for. *Plumbers who replaced pipework - shoddy - broke our toilet, caused many leaks (still finding some), had no respect for our property, left a mess. *ASHP install - ripped off a cover, balanced it back in place, didn't tell anyone, rain got in, system tripped. Left without heating for sometime while waiting for Vaillant to come out and sort. After trying to blame us for the failing? *Vaillant engineer pointed out our ASHP is an Aerotherm model not Aerotherm+ which we were quoted for? If we had any verbal comms about this change it hadn't been confirmed in writing and doesn't reflect in any paperwork we have received. * cold weather electric tripped - again blamed us/electrician and cable installed, our electrician installed as FDGs electrician advised us. caused a leak too. No response to rectify and this happened in Jan or Feb. *Green grant - well don't hold your breath, they may tell you its sorted fast but they don't even reply to various chase up requests to get it finalised. Very unhappy with the install and the none existent customer service. Will be logging complaints with all regulatory bodies and trading standards.

The trader replied (on 18/05/2021)
Good afternoon, If you see our other reviews you can see this is not how we operate. You asked us to repipe a 600 year old derelict property. Every inch of pipe is brand new and we refitted your old bathroom back. If there was any problem a call would have been all it took. The cover on the rear did break its a common issue. Vaillant had said they are waiting for more to be sent from Germany. They said tape it and they would go out to fix it which they did. As for the delay there was no plus heatpumps available and you wanted to move in so we upgraded you to a Split at no extra cost. As for the electrics your Electrican was briefed in what to do and he didn't do it as agreed. Hense all the electrical issues you've had. Your side was responsible for the electrical side. But as it was done incorrectly we sent up a specialist also at our cost to rectify. As for the green grant you are in receipt of the renewable heat incentive. The green homes grant is a complete failure. Not a single voucher has been paid since last September. This is down to them not us. We recommend no one uses the green homes grant and just pushes for the RHI. To add repiping a 600-year-old house with radiators and a state of the art split heat pump system cost us £18400.00 in materials and costs. You paid £20000.00 and you get £12000.00 back. In the middle of a lockdown so apologies that we struggled to get back to some customers. We have improved the service no end.
Fabulous system
Customer Service
Wonderfully comfortable system.. I love the fact that it helps the environment. So much better than my old oil heating system. The installation went very smoothly. The installers seemed extremely proficient and knowledgeable as well as congenial and polite.

UPDATED REVIEW: Snagging now nearly sorted.
Customer Service
UPDATE (received 08/04/2021): Further to my review of 25/03/2021. Today we've had a satisfactory visit from an FDG engineer to resolve outstanding snagging issues. Today's work was done to a good standard, and the one outstanding issue should be straightforward, once a new part is available. Certainly, into the future we are hoping that we can have a good ongoing relationship, as FDG maintains our ASHP system over the next 10 yrs. I was assured by today's engineer that FDG are working on after-sales responsiveness, with promise of a better level of communication when unforeseen events change the dates and times that engineers can attend to undertake work. I look forward to seeing this in practice. -------------------------------------------------------------------------------------------------------------------------------- ORIGINAL REVIEW (received 25/03/2021): With a heavy heart I write this review - as I am still hoping that the issues I raise will be remedied. I will gladly write a further review once issues are sorted. There was great enthusiasm from FDG group team members prior to installation, but it is difficult to motivate the sorting of snagging issues - now nearly 2 months on. Installation was said to take 3 days but took a week. I wait in for a visit and, only when I chase them up, I am told there was an emergency. The Vaillant ASHP circuit intermittently depressurizes for no obvious reason. Very poor quality of plumbing in the loft shows that there was insufficient supervision of junior tradesmen. The outdoor unit drips condensation - but has not yet been fixed. It seems to me that FDG are attempting to grow too quickly - and are not adequately supervising their sub-contractors. I hope that our issues will be sorted soon, and others do not have the same experience as us.

Air source heat pump
Customer Service
FDG via its subcontractor gas smart installed the air source heat pump system. Upon completion, they left with the bathroom radiators not working and have refused to sort it out, blaming it on other building works. The installer struggled to understand the plumbing and did not know much of the controls. The system was overheating and despite complaining about it, we were told that it would settle on its own. We had to contact Vaillant to get the settings changed on the system. Jon orange has since visited and has refused to sort the towel radiators problem. They broke the floorboards, destroyed the underlay and left us with no heating for a whole week. NEVER, NEVER GO WITH THEM...They do not understand their products and are unwilling to sort out the problems they have created.

Excellent Service beyond expectation!
Customer Service
From the moment we contacted FDG to the completion of the work we are so impressed with all of the team as well as the superb standard of the work. The whole team answered our questions no matter how trivial in a very professional and helpful manner. There was someone on call every step of the way that was extremely reassuring. It was a big decision for us to completely upgrade our heating and energy platforms, removing our gas boiler and replacing it with an Air source heat pump and an array of solar panels. However, the team reassured us all of the way and every part of the process explained was carried out perfectly. The standard of work was some of the best I have ever seen and the fitting team so helpful and accommodating. We were kept informed all the way through the fitting process and our input was encouraged which helped us not only understand the system better but also allowed us to influence how best the team could bespoke the system to our needs. The process was seamless all the way through, with the friendly teams working well together. The finished result has impressed our friends and family alike. The system initially is so smart it can be hard to grasp how it actually works but as said, the team has been on the end of a line 24/7 to answer any queries we had. We are so pleased with our decision to future proof our house. The added bonus of the RHI scheme also makes this so affordable along with the long term savings. We would thoroughly recommend to all.

A professional company with integrity
Customer Service
We have waited a while to review FDG Group to ensure the product and service reflected what we wanted and what was promised. We also wished to compare our energy usage v cost to be able to provide an honest review. We moved into our 'new' property in March 2019 with just weeks before the FiT ended. As part of our renovation project, energy efficiency is high on the agenda. Initial discussions with FDG were positive (although I would encourage anyone to do their own calculations before speaking to a 'salesman'). We didn't really require the hard sell, we wanted solar panels and more importantly battery storage to make the investment cost effective. In addition, we also have 'free' hot water via an iBoost. The installation was straightforward, a minor confusion on where the kit was to be installed but not an issue as it can be moved at a later date if required as part of the bigger renovation project. The aftercare is fantastic, I cannot name another company in any field that has provided such a high level of service. We have had a problem with the export meter which subsequently damaged our first quarter FiT payment. You have to expect teething problems and although we lost a little money, it was fixed easily and efficiently by FDG. We have received several phone calls in relation to the install and ongoing satisfaction of the product, any issues that do arise we are always encouraged to call immediately.
