No, but it’s vital you check that the group hiring the building has its own public liability insurance that covers the event they are holding. If anyone is injured in the church due to negligence on the PCC’s behalf, you’ll be covered by your church policy, or by your church hall cover (if insured with us) if they’re injured in the church hall.
You should make sure that the buildings are well maintained so that they’re safe for people to use. Carry out a risk assessment of the building and the activities that are planned, and if you identify any risks make sure you take steps to minimise them. You should carry out risk assessments regularly so you can be sure they’re up to date. Make sure to write everything down, as this could be used to defend the PCC against any claim.
