The Fire Safety Order gives fire authorities significant enforcement powers. We explain the hierarchy from informal advice to prosecution.. Enforcement Hierarchy Fire and rescue authorities have a graduated enforcement approach: 1. Informal notification — advice letter highlighting deficiencies 2. Formal notification (Article 31) — official notification of fire safety deficiencies 3. Enforcement notice — legal requirement to remedy deficiencies within a timeframe 4. Prohibition notice — immediate closure of premises where serious risk exists 5. Alterations notice — requirement to notify before making changes 6. Prosecution — criminal proceedings for serious breaches (up to 2 years imprisonment and unlimited fine) Building Safety Act Powers The BSR has additional powers for higher risk buildings including compliance notices, building assessment cancellation, and criminal prosecution of duty holders.
