The enforcing authority have the power to inspect your premises and to check that you are complying with the current legislation; they will also require proof that you have an adequate Fire Risk Assessment for the premises.
If the enforcing authority is dissatisfied with the outcome of your fire risk assessment or the action you have taken, they may issue an enforcement notice that requires you to make certain improvements, or in extreme cases a prohibition notice, that restricts all or part of your premises until improvements are made.
