The cost of getting building safety wrong

The cost of getting building safety wrong is usually counted after the fact, in remediation bills and enforcement notices. But the larger cost is quieter and arrives earlier: it is the accumulating expense of a building whose records cannot answer the questions put to them, whose obligations are tracked in someone's head, and whose compliance is reconstructed in a panic whenever it is challenged. By the time the visible costs appear, the invisible ones have usually been paid for years.

The regime built after Grenfell has raised the stakes considerably, and the direction of travel is towards more scrutiny, not less. Understanding where the costs actually fall — and that the avoidable ones are mostly upstream — is the difference between managing a building and being managed by it.

The system the failures reshaped

The framework managers now work within exists because the old one was found wanting. The Grenfell Tower Inquiry Phase 2 report, published 4 September 2024, ran to seven volumes and roughly 1,700 pages and made 58 recommendations, 37 to government and 21 to other bodies (gov.uk; Bevan Brittan; FBU). Its first recommendation was a single construction regulator for England and Wales, the report having described the previous regime as too complex and fragmented (Construction Briefing). The government accepted the direction, and a single construction regulator is expected to be operational from 2028 (Building; gov.uk).

That is the macro cost — a wholesale reordering of how the sector is regulated, paid for collectively. For the individual manager, the question is narrower: what does getting it wrong cost me, and where is that cost incurred?

Enforcement is the visible end

The most visible cost is enforcement. Under the Building Safety Act 2022, occupied higher-risk buildings — those at least 18m tall or with at least 7 storeys and containing at least two residential units (gov.uk; RICS; ICE) — must be registered, must have an Accountable Person or Principal Accountable Person, and must hold a safety case report the Building Safety Regulator can examine (RICS). The BSR became Building Control Authority for all higher-risk buildings in England in October 2023 and, from January 2026, is being established as a standalone body (ICE; Building).

A regulator with that mandate can compel action, and the cost of being compelled is always higher than the cost of acting in good order. But enforcement is the symptom, not the disease. By the time a notice arrives, the underlying failure — a record that was never kept, an obligation that was never tracked — has usually been present for a long time.

The costs that accrue quietly

Most of the real expense of getting building safety wrong never appears as a fine. It accrues in ordinary operation, in forms that are easy to discount individually and ruinous in aggregate:

• Duplicated effort, because the same information is gathered repeatedly by people who cannot find what already exists.
• Reactive emergencies, because a missed planned check became an unplanned failure.
• Stalled transactions, where a sale, a refinance or an insurance renewal hangs on records that cannot be produced quickly.
• Lost institutional knowledge at every change of staff or managing agent, because nothing was written down in a form the next person could use.

Each of these is a tax on disorder. None of them generates an invoice with "building safety failure" written on it, which is exactly why they are tolerated for so long. Set side by side, the two kinds of cost behave very differently.

The pattern is consistent: the avoidable costs are the quiet, continuous ones, and they are also the cheapest to prevent.

Why the record is where the cost is decided

The thread connecting the visible and invisible costs is the record. The Building Safety Act 2022 frames the golden thread as an accurate, up-to-date digital record of building information held through design, construction and occupation (ICE). A manager who has that can answer a regulator, satisfy an insurer and brief a new colleague at speed. A manager who does not pays — in enforcement risk, in duplicated work, in transactions that stall — every time the building is questioned.

The economics are unsentimental. The cost of keeping a current record is small, predictable and spread over time. The cost of reconstructing one under pressure is large, unpredictable and concentrated at the worst possible moment. Getting building safety wrong is, more often than not, a records failure that only later becomes a safety or enforcement failure. We have written more about how a regulator reads the trail in reading a regulator's enforcement notice.

Predictable work is the cheap work

The reassuring part is that most compliance is predictable. The servicing intervals, the inspection cadences, the FRA review, the statutory checks — these are known in advance and can be budgeted and scheduled. The Fire Safety (England) Regulations 2022, in force 23 January 2023, require monthly checks of firefighters' lifts and key equipment in high-rise residential buildings (NFCC; gov.uk); LOLER requires lift examinations every six months for passenger-lifting equipment (HSE). None of this is a surprise. The expensive failures are the ones that turn predictable work into unplanned emergencies because nobody was tracking the date.

A compliance calendar that chains its own deadlines is, in cost terms, one of the highest-return controls available, precisely because it converts the most expensive failures back into the cheapest routine work.

Spending where it counts

The honest summary is that getting building safety wrong is rarely a single dramatic event. It is the slow cost of disorder, occasionally punctuated by an expensive one. The way to avoid both is the same: keep a current record, track the obligations you can predict, and make sure the building can answer the questions that will be asked of it.

In SAMRISK, that means the safety case, the audits, the certificates and the calendar sit together against each building, so the record is a by-product of running the building rather than a project undertaken in a crisis. The cost of getting it right is modest and known. The cost of getting it wrong is neither.
