- Fire Safety Act 2021: What It Changes & Who It Affects
Fire Safety Act 2021:
The Fire Safety Act 2021 was introduced to clarify how the Regulatory Reform (Fire Safety) Order 2005 applies in multi-occupied residential buildings. In particular, it makes clear that the Fire Safety Order applies to a building’s structure, external walls, and flat entrance doors between domestic premises and common parts. That includes relevant external wall systems such as cladding, balconies and windows where fire risk needs to be considered.
This was an important legal change because, before the Act, there had been uncertainty about whether these parts of a building were fully within scope of fire risk assessment duties under the Fire Safety Order. The Act was designed to remove that uncertainty and make responsibilities clearer for responsible persons, landlords, managing agents and others with fire safety duties.

A Clearer Scope for Residential Fire Safety Duties
In practice, the Fire Safety Act 2021 means that, where a building contains two or more sets of domestic premises, the responsible person must make sure their fire risk assessment properly considers the structure, the external walls, and flat entrance doors if those elements have not already been assessed. The Act therefore sharpened the legal focus on building fabric and fire spread risk, not just the internal common areas.
The Act matters most in multi-occupied residential buildings because those buildings often involve shared escape routes, common parts, flat entrance doors and external wall systems that can have a serious effect on life safety. By clarifying the law, it became easier for responsible persons and enforcing authorities to identify what must be considered as part of proper fire safety management.
What the Fire Safety Act 2021 Changed
The Fire Safety Act 2021 is closely tied to the Fire Safety Order. Rather than replacing it, the Act amended it to make the position clearer in buildings containing two or more domestic premises. That means the responsible person must consider more than just the obvious communal escape routes. They must also look at how the structure, external walls and flat entrance doors may affect fire risk and fire spread.
This is especially important in buildings where external wall systems, cladding, balconies, insulation, windows or entrance doors may influence compartmentation or the spread of smoke and fire. The Act was intended to make sure these matters could no longer be overlooked within the fire risk assessment process.
This can include:
- Clarified the scope of the Fire Safety Order in multi-occupied residential buildings.
- Confirmed that the structure of the building must be considered where relevant.
- Confirmed that external walls fall within scope, including relevant attachments such as cladding and balconies.
- Confirmed that flat entrance doors opening onto common parts must be considered.
- Strengthened the link between residential building risk and fire risk assessment duties.
- Helped remove legal uncertainty for responsible persons and enforcing authorities.
Who the Fire Safety Act 2021 Affects
The Act mainly affects responsible persons for multi-occupied residential buildings, along with landlords, freeholders, managing agents, housing providers and others with fire safety duties under the Fire Safety Order. It is particularly relevant where a building contains two or more domestic premises and shared common parts.
It also affects fire risk assessors and those advising on compliance, because it makes clear that risk assessments in relevant buildings must not ignore external wall systems or flat entrance doors. In other words, the Act raised the standard for what a suitable and sufficient assessment must take into account in those settings.
The Act did not replace the Fire Safety Order. It clarified how the Order applies in certain residential buildings.
Responsible persons must consider relevant external wall systems, including cladding, balconies and other attached elements where they create fire risk concerns.
The Act makes clear that flat entrance doors opening onto common parts are part of the fire safety picture in multi-occupied residential buildings.
The Act is especially relevant where a building contains two or more domestic premises and shared common parts.
Responsible persons must ensure their fire risk assessments account for the elements clarified by the Act if not already covered.
By clarifying scope, the Act makes it easier for compliance duties to be understood and, where necessary, enforced.
Key Takeway:
The Fire Safety Act 2021 is important because it removed doubt about what must be considered under fire safety law in multi-occupied residential buildings. For responsible persons, it means there is far less room for uncertainty around external walls, building structure and flat entrance doors when reviewing fire risk and compliance duties.
