Yes, I have had a mixed experience with this company. We have undertaken a new build and approached ESP at the NSBRC in Swindon for all our energy products, that is MVHR, Ecocent Hot water, Heliotherm ASHP and lastly, but the most painful, a 10kw PV as in-roof array. All in all we have spent over £50,000 on energy products. The "internals", UFH, MVHR, ASHP etc were all done professionally and as I would have expected by a competent company, the PV array however was a different story. The installation was done poorly, has taken over two years of constant communication with the chairman, Harold Wilson, re trying to fix poor paperwork, noisy inverter, mismatched panels, buckling flashing and lastly but not least, failing our 10yr warranty for the PV installer puncturing our roof waterproof membrane no less than 150 times with the fixing screws through the battening for the panels. Oh, I nearly forgot, we paid for a 10kw array and shifted from a single phase supply to three phase as the best way due to the limit of 3.4kw on single phase by Western Power. Our reason for 10kw? Because we knew that the british climate meant we would struggle to get a full output throughout the year but at last we should get enough for home use during cloudy periods too with such a size. Our roof could take it and the cost was double but the output was treble. Unfortunately I had to find out myself that our 10kw array wasn't in reality a 10kw array but split into three over the three phases, which meant it was an impossibility for us to charge our electric vehicle via our purchased 7kw charging point without drawing from the grid as the max we could get on a bright sunny day was 3.4kw over that phase. When I approached Harold with this fact that we had been left with something that was not what we bought, he started quoting warranty and taking it up with the PV installer (subcontracted by ESP, which I was never made aware of, and subsequently gone bust). All in all, totally unhelpful and not what I expected, considering the excellent work done on the other aspects of the energy work.
To date over those two years of complaining, we have had the inverter exchanged for the obsolete model installed which has no fans, much quieter, but have lost the remote internet access we had with the former inverter, the incorrect paperwork was never corrected, the mismatched panel, never corrected, the buckling flashing, seems to be fixed after third visit and intervention of Nick Hales from ESP, but we await the hot weather to see, the incorrect design (split over three phase?), still denial from Harold, the latest 150+ punctures to the waterproof roof membrane?, no reply whatsoever from Harold. As you can see, this approach from Harold Wilson of ESP has left a blight on an otherwise dream build which is still ongoing and looks like it may well have to go to court to be resolved. Would I recommend this company to anybody? Mixed. I would deal with Nick Hales again as he bent over backward to help with any issues with the ASHP, UFH and MVHR etc. Would I deal with Harold Wilson? Absolutely not and I would definitely NOT recommend this company as he is the chairman.
