The Fire Safety Act 2021 fundamentally changed fire safety obligations for multi-occupied residential buildings. This comprehensive guide covers everything you need to know and do.. What the Fire Safety Act 2021 Changed The Fire Safety Act 2021 amended the Regulatory Reform (Fire Safety) Order 2005 to clarify that for multi occupied residential buildings, the FSO applies to: The structure of the building — including structural frame, floors, and walls External walls — including cladding, balconies, and windows Flat entrance doors — doors between individual flats and common areas Common parts — corridors, lobbies, staircases, and shared facilities This clarification was necessary because before the Act, there was legal ambiguity about whether external walls and flat entrance doors fell within the scope of fire risk assessments. Why This Matters Before the Fire Safety Act: Many fire risk assessors did not inspect external walls or flat entrance doors Building owners argued that flat entrance doors were the leaseholder's responsibility External wall assessments were not routinely conducted The scope of the Responsible Person's duty was unclear "The Fire Safety Act didn't create new obligations — it clarified obligations that should always have existed. The fact that clarification was needed tells you everything about the state of fire safety regulation before Grenfell." The Fire Safety (England) Regulations 2022 The Regulations provide the detail behind the Act, specifying what Responsible Persons must actually do: Fire Risk Assessment Requirements Fire risk assessments must now explicitly cover external walls and flat entrance doors Assessments must be conducted by a 'competent person' (though competence is not defined in law) The assessment must be recorded in full (not just a summary) Assessments must be reviewed regularly and after any material change Information Sharing The Responsible Person must share the following with residents: Fire risk assessment — make the full assessment available on request Fire safety information — provide to all residents, including fire action notices Fire door information — inform residents of the importance of self closing fire doors Building plans — provide building floor plans to the local fire and rescue service Fire Door Requirements For buildings over 11m (approximately 4+ storeys): Quarterly checks of all fire doors in common areas Annual checks of all flat entrance doors Best efforts to inspect flat entrance doors (residents cannot be forced to allow access) Records of all fire door inspections must be maintained Smoke and CO Alarms Smoke alarms required on every storey of residential buildings (already required under Smoke and CO Alarm Regulations) CO alarms required in rooms with fixed combustion appliances (gas fires, boilers) Lifts and Evacuation Equipment For buildings over 11m: Information about lifts must be provided to the fire service Evacuation plans for residents unable to use stairs must be developed Monthly checks of evacuation equipment (chairs, mats, etc.) where provided Who Is the Responsible Person? The Responsible Person is typically: Freeholder — if they control the common parts of the building Management company — if appointed to manage the building Right to Manage company — if residents have exercised their right to manage Local authority — for council owned housing stock Housing association — for social housing Multiple Responsible Persons In buildings with multiple dutied parties: The obligation falls on whoever has control of the relevant part of the building If multiple parties have control, all are Responsible Persons for their area They must co operate and co ordinate with each other A lead Responsible Person should be identified for the whole building Enforcement and Penalties Fire and Rescue Service Powers The fire service can: Inspect the building and request documentation Issue informal advice recommending improvements Issue enforcement notices requiring specific actions within a timeframe Issue prohibition notices restricting or prohibiting use of the building Prosecute for non compliance with the FSO Penalties Non compliance with enforcement notice : Unlimited fine Failure to maintain adequate fire safety measures : Up to 2 years imprisonment (on indictment) Putting persons at risk of death or serious injury : Unlimited fine and/or imprisonment Practical Implementation Checklist 1. Identify the Responsible Person(s) for your building 2. Commission a fire risk assessment by a competent person, explicitly covering external walls and flat entrance doors 3. Implement all recommendations from the fire risk assessment with documented action plan 4. Share fire safety information with all residents 5. Establish fire door inspection programme (quarterly common areas, annual flat doors) 6. Provide building information to the local fire and rescue service 7. Develop evacuation plans for residents who cannot self evacuate 8. Maintain records of a
