In 2026, UK building owners are expected to hold: a fire risk assessment recorded in full (all buildings covered by the Fire Safety Order); quarterly communal and annual flat entrance fire door check records (residential buildings over 11 metres); a digital “golden thread” of building information (higher-risk buildings of 18 metres or seven storeys); evacuation plans for residents who need assistance (from April 2026); and evidence of fire protection works: what was installed, where, when, by whom and with which materials.
That last category is where the distinction that increasingly separates well-run assets from troubled ones shows up. It isn’t whether the building is fire-safe; it’s whether the owner can prove it. A building can have perfectly good fire-stopping behind its walls, but if nobody can evidence the work, then as far as a regulator, an insurer, a lender or a buyer is concerned, it may as well not exist. Increasingly, the record is the asset.
UK fire safety record-keeping requirements in 2026
The direction of travel is unmistakable. The Building Safety Act 2022 created the golden thread, a digital, accessible record of building information that must be created for higher-risk buildings and kept current through the building’s life. Since October 2023, section 156 of the same Act has required every responsible person, in every building covered by the Fire Safety Order, to record their fire risk assessment in full. The Fire Safety (England) Regulations 2022 added quarterly communal fire door checks and annual flat entrance door checks in residential buildings over 11 metres. These duties only mean anything if they are documented.
The pace has not slackened this year. The Building Safety Regulator became a standalone body, moving out of the Health and Safety Executive at the start of 2026, with a mandate to sharpen scrutiny of higher-risk buildings. From 6 April 2026, the Fire Safety (Residential Evacuation Plans) (England) Regulations require responsible persons in taller residential blocks to identify residents who may need help evacuating and put person-centred plans in place: another duty, another record. And developers face the updated Approved Document B from 30 September 2026, including second staircases in new residential buildings over 18 metres.
Every one of these measures shares a design principle: the burden of proof sits with the building owner, permanently.
How missing fire safety records affect valuations, insurance and sales
The financial consequences of thin records are no longer theoretical. Refinancing and disposals stall while lawyers chase documentation that should take minutes to produce. Insurers price uncertainty into premiums, or exclude what can’t be evidenced. Remediation disputes turn on precisely the questions undocumented buildings cannot answer: who installed what, when, and with which materials. That leaves owners funding investigations into their own walls before they can even apportion liability.
And in transactions, the discount is real. Two comparable blocks come to market; one produces a complete, current evidence pack (fire risk assessment recorded in full, fire door check history, remediation records with photographic proof) and the other offers certificates of unknown provenance and a promise to dig further. Buyers price the second building’s uncertainty, if they proceed at all. Provable fire safety has become a component of value in the same way a clean title is, and it sits alongside the other hidden issues that quietly damage property values and transactions when they surface late in due diligence. The difference is that this one is entirely predictable.
How fire safety compliance evidence is created on site
Here is the part owners and asset managers sometimes miss: the records that regulators, insurers and buyers want don’t originate in the boardroom. They originate on site, at the moment a fire door is inspected, a penetration is sealed, a damper is fitted or a cavity barrier goes in. If the evidence isn’t captured then, it is reconstructed later at great cost, or never. And on sites where construction schedules are under pressure from the moment they’re approved, any record-keeping that adds friction is the first thing to be skipped.
That is why the fire protection trade’s own digitisation matters so much to the people who own the buildings. Contractors increasingly record their work through fire protection software, capturing time-stamped photographic evidence of each install and inspection, pinned to an exact location on the building’s drawings, with materials logged and the whole record exportable as structured reports for clients and auditors. Work evidenced that way arrives golden-thread-ready: a location-referenced, chronological account of what sits behind the finishes, produced as a by-product of doing the job rather than as an afterthought.
For an owner, the difference surfaces years later, when a regulator asks, an insurer queries, or a buyer’s technical team wants to know exactly what was installed on level six.
What building owners should specify when procuring fire protection works
The practical response is to treat evidence as a deliverable, contractually. When procuring fire safety works (surveys, fire-stopping, fire door remediation, damper maintenance), specify digital, location-referenced photographic evidence for every item of work, with material records, and a structured handover that slots into the building’s fire safety information under Regulation 38 and, for higher-risk buildings, the golden thread. Ask prospective contractors to show how their records are captured and produced; the answer reveals a great deal about what the handover will look like.
For standing assets, the same logic applies to the ongoing record: fire risk assessments, door check schedules and remediation histories held in a form that can be retrieved in minutes, not reassembled over months. And in acquisition due diligence, ask for the evidence pack itself: not a list of certificates, but the underlying proof of what was done and where.
Frequently asked questions
What is the golden thread under the Building Safety Act?
The golden thread is the digital record of a higher-risk building’s information covering its design, construction and ongoing safety management, created through the building’s gateway approvals and maintained by the accountable person once occupied. It must be accurate, accessible and kept up to date throughout the building’s life.
Do all buildings need a written fire risk assessment?
Yes. Since 1 October 2023, section 156 of the Building Safety Act requires every responsible person under the Fire Safety Order to record their fire risk assessment in full, regardless of the building’s size or the number of people employed.
What fire safety changes take effect in 2026?
Three stand out: the Building Safety Regulator became independent of the HSE in January; the Fire Safety (Residential Evacuation Plans) (England) Regulations came into force on 6 April, introducing evacuation-planning duties for taller residential buildings; and the updated Approved Document B applies from 30 September, including second staircases in new residential buildings over 18 metres.
The bottom line
Fire safety has moved from an operational cost line to a balance-sheet consideration, and the hinge is provability. The regulatory regime, reinforced again in 2026 by a standalone regulator and fresh duties, assumes owners can evidence their buildings continuously. The ones who can are finding that transactions, insurance renewals and regulatory engagements run faster and cheaper. The ones who can’t are discovering that an undocumented building is, in the eyes of everyone who prices risk, a different and lesser asset.
