In the booklet "The Design of Free-standing Walls", there is a map
showing the speeds that are used for building design in the UK. I
am not going to summarise it (as it is very complex), but here are
a few examples:

London 37
Colchester 41
King's Lynn 44
Newcastle 46
Truro 48
Edinburgh 50
Glasgow 52
Lewis 55

Interested to know how they derived those figures, and whether builders are
legally required to use those figures. I wouldn't worry about your house
blowing down - even the lowest figure (for London) is over F12 on the
Beaufort scale and barely survivable in the open.
