The installation when it finally happened was good. It certainly wasn't easy given my supply enters the house through a solid floor and ends up in a cupboard under the stairs. I knew therefore this would be a non standard installation and indeed it took nearly 5 hours but the result is a neat and tidy finish and the unit works perfectly so far. However the install was only after the company (Sol Electrical) had made two previous appointments which they failed to make resulting in me wasting the best part of two mornings and making two unnecessary phone calls. I did as a result get the engineer to reduce the extra charge from £100 to £60 (+ VAT) for the inconvenience but in the light of my experience I would not be confident in recommending anyone to choose this charger.
