RE St Pauls - They can only be dealt with through an insurance broker I think,
or at least that used to be the case years ago.
They were part of the "Travellers Insurance company LTD".
I think this Travelers Ireland
is the Irish site, but they are a huge international company and AFAIK do lots of specialist insurance in the UK.
BTW they might have dropped the St. Pauls bit from their name recently perhaps?
My current 2008 insurance cert has
"Travelers Insurance Company LTD" on it.
My 2007 one had
"St Paul Travelers Insurance Company LTF"
And an earlier one had
St Paul International Insurance Company LTD
So maybe the St Pauls name was being absorbed into the Travelers brand or something.
Sorry I cant be more helpful, since I have had no direct dealings with them myself, I just dealt with my insurance broker.
I'm sure folks on the Pistonheads forum or similar might have ready local info for you..
