Fire Safety Act 2021 — what it changed, and why you now cite the Order instead

What it requires

The Act does not, by itself, impose duties on anyone. It is an amending Act, and its work was to settle an argument.

Before it, there was genuine uncertainty about whether the Fire Safety Order reached the structure and external walls of a multi-occupied residential building, and the entrance doors to individual flats. Section 1 removed that uncertainty by clarifying that where a building contains two or more sets of domestic premises, the Order applies to those elements. Section 3 amended the guidance power in article 50 of the Order.

Section 2 does something different: it gives the Secretary of State, and the Welsh Ministers, power to make regulations changing or clarifying which premises the Order applies to.

What this means in practice

For day-to-day compliance work, the practical answer is that you cite the Order, not this Act. Sections 1 and 3 did their work at the moment they commenced and are now part of the Order's text. A fire risk assessment that needs to state the legal basis for including external walls or flat entrance doors is citing article 6 of the Order as amended, not section 1 of the 2021 Act.

The Act still matters for two reasons. It explains why the Order reads as it does, which is useful when reading an assessment or a report written before the amendment took effect. And section 2 remains available: the scope of the Order can be changed by regulations without further primary legislation.

Where it stands

Fully commenced, with no outstanding effects recorded at the date checked. Note that commencement differed by nation — section 1 came into force in Wales on 1 October 2021 and in England on 16 May 2022 — so a Welsh building and an English building were subject to the clarified position at different times. That difference can matter when reading an assessment carried out in that window.

One caveat on currency: legislation.gov.uk did not display an "up to date with all changes known to be in force on or before" line for this Act when checked, so the date recorded on this page is the date we verified it, not a currency the source itself vouched for. The page did state that there are no known outstanding effects.
