Hi,
Thanks for the replies.
The house has a cavity but I have been cautioned against getting cavity
insulation as it alows moisture to bridge from the stone layer through to
the inner brickwork.

Who told you that?

We've had it for years and hzve been 100% satisfied with it on all counts.

Dear All
It all depends on the insulation! The whole idea and purpose of the
cavity is to prevent water going from outer to inner leaf. So.....any
form of insulation that bridges this permanently in such a manner that
water can get thru is not appropriate. Ideally, as with most building
alterations, it is best to be reversible i.e. you can suck out the
insulation as in beading or rockwool blown fibres etc as opposed to PU
foam or the like which sets and that is it!
In other words - chose the right product and application method and
its fine to do
