1. I was told i would be given a date for the install within 3-5 days. This did not happen and i had to chase it up. 2. Whilst the install was done efficiently and well the unit could not be activated becasue the RCD on the circuit to which it was attached was not a 'type A'. I had already had my electrician out to do some work ahead of the install. If i had known ahead of time this was a requirement i could have got him to address it at the same time. As it was i had to get him back which involved more expense and delay. I do not know why the reqt for a type A RCD is not flagged up front in the process, not after the install.
