It was ok, the installation took 3hrs and 15 mins. The electrician was polite. The charger is on the wall and works. I did have my electrician pre-fit an isolator so that no drilling or damage would be necessary, but the electrician said that i had to have another cable fitted in case the supply was overloaded, even though the new power supply was 3 core 25mm armored cable from the house. I heard hammer drilling, even though the garage is timber frame, and the electrician had drilled from inside and split out the timber cladding which was a shame. Anyway....it works
