We're in Wales and are going to get in touch with Western Power
distribution tomorrow but I have a feeling that an electrician will be
required, hence the initial question re good, reliable electricians in
the area.

Do I go for an electrician with certain credentials to avoid the
cowboys?

I've used local electric PoCo as they were less than
half the price of local contractors.
By 'trip' do you mean an RCD or an MCB ?
