Whether compensation is appropriate depends on the circumstances in each case.
This from PACE Code B:
"Compensation for damage caused when effecting entry is unlikely to be appropriate
if the search was lawful, and the force used can be shown to be reasonable,
proportionate and necessary to effect entry. If the wrong premises are searched by
mistake everything possible should be done at the earliest opportunity to allay any
sense of grievance and there should normally be a strong presumption in favour of
paying compensation."

In essence this means that provided the police did not get the address wrong and forced entry under lawful execution of a warrant or in their duty to protect life and limb they would normally not pay compensation, however an ex-gratia payment would be considered, for repair costs only, where the claimant either has no insurance or their insurers are refusing to cover them because the damage is outside the scope of their policy.
