English magistrates courts can issue a warrant of entry. This gives the right to force entry provided the correct procedures are followed.
Even without a warrant if you give a bailiff entry into your property they can take 'Distraint' over any goods or chattels they see. They do not need to remove them at that time but may then come back. This is probably where the confusion comes from, google distraint.
Rules are different for utilities, other creditors or Customs and Revenue.
