Homeserve are pants
Yes it was their own man who came out initially. When the original installer came, it took him about half an hour and was aghast at what had gone on.
If that's their own tech then that's disappointing; new boards cost up to about £100 (see Ebay) and swapping them should be an easy half hours work.
ditto, Scottish power phoned me to offer this deal but already get it included with admiral house insurance
I signed up to homeserve hastily, tempted by an offer making it £3 a month. It rose to £14 a month in the 2nd year, all with a £95 excess. The one time I had to use them, I paid a £95 fee and they guaranteed someone would come the same day as we've got 2 toddlers. After a series of cancelled appointments, someone eventually turned up 2 days later and fixed it within 5 minutes.
