It took ages to get a survey done, then once it was done it took ages to get the installation agreed. Finally they gave me 3 different dates (they didn't realise this was what they were doing - chaos). Once that was sorted out the engineer came and fitted it and as soon as he left switches started tripping all over the house every time we put a load on them, even without the car plugged into the charger. The office gave me a date two months ahead to fix the problem. Luckily, I was able to get hold of the engineer the next day and he offered to come back, which he did, without the office knowing. He started remedial measures but when his boss rang me up to respond to my complaint, not knowing the engineer was here, it turned out he was doing the wrong thing. So he had to start again. In the end it works fine now. But it was like dealing with the general post office before privatisation. Like they were doing me a favour. I was left with little confidence. Hopefully I won't have to deal with them again. They also sold me a charger lead I didn't need because it comes with the vehicle, and wouldn't take it back.
