pcmesq - the building will already be insured. Ask the people you're buying the freehold from for a copy of the policy certificate (our freeholder always sent us a copy with the bill we had to pay for it). When I bought our freehold, I then just contacted the broker named on the certificate and changed the name on the policy (the policy was paid up until June and we purchased the freehold in March). Now we have to renew the insurance policy, the insurer and broker we're with already are offering us a good deal to stay with them.
