After Grenfell, the law changed — and so did developers’ balance sheets. The Building Safety Act 2022 made building owners and the developers who built them responsible for fixing unsafe cladding, backed by a legally-enforceable industry deal worth around £5 billion. The public story is a government progress table. The more useful question — which specific companies are carrying this liability, and which are starting to strain under it? — is one only GalimAI’s data can answer. This study uses that proprietary view.
What GalimAI’s own data reveals
A remediation liability is only useful intelligence if you can attach it to a specific company — and that is precisely what GalimAI’s map does. Within the 463,022 property-owning companies and more than 1,000,000 owners it tracks across England and Wales sit the freeholders, developers and building-management companies the Building Safety Act made responsible for unsafe cladding. Each is linked to its directors, its filing and charge history, what it owns and the distress signals around it.
That is the difference between a national headline and a workable list. The Act turned a deniable risk into a dated, enforceable cost; GalimAI’s data shows which companies are carrying it and which are starting to strain — the most heavily-leveraged owners, those flashing stacked distress signals, and the concentrations in GalimAI’s regional distress map. A large diversified housebuilder can absorb a nine-figure provision; a single-building freeholder or small developer with no other income is exactly the company whose distress GalimAI surfaces first.
For an investor or counterparty that is the unique edge: the building-safety overhang becomes visible at company level — which owner, which directors, which financing — so the liability can be assessed and the owner reached directly, rather than inferred from a government progress table.
What changed: from Grenfell to a legally-binding pledge
The Building Safety Act 2022 received Royal Assent in April 2022. Alongside it, the government secured a legally-enforceable agreement on 13 April 2022 under which major housebuilders committed to fix life-critical fire-safety defects in buildings over 11 metres that they had built — around £5 billion of funding in total, with developers committing roughly £2 billion to their own buildings and the wider industry £3 billion through an expanded levy, on top of a new Residential Property Developer Tax.
The Act also extended the windows in which owners can be pursued for defects — retrospectively, by up to 30 years in some cases — and created the Building Safety Regulator, whose approval is now required before remediation can start on higher-risk buildings.
The public backdrop
| Developer | Cladding-remediation provision |
|---|---|
| Barratt | ~350m-400m pounds extra, on top of 184m already provisioned |
| Taylor Wimpey | ~245m pounds |
| Persimmon | 75m pounds |
The largest housebuilders could absorb these nine-figure provisions. The harder problem is pace and who is left holding the bill: by January 2025, 96% of the 514 high-rise ACM buildings had started or completed remediation, but of 5,025 buildings 11 metres-plus identified with unsafe cladding only 48% had — with a 2029 deadline now applying or landlords face penalties. The public table stops there; GalimAI’s map shows which of those owners are strained.
The most plausible mechanism
Regulation turned a contingent, deniable risk into a dated, enforceable liability with a price tag. Large developers diversified across hundreds of sites absorbed the provisions; the pressure concentrates further down — on freeholders and smaller developers who own one or a handful of affected buildings, face the same fixed cost and regulatory delay, but have no diversified income to carry it. We present this as a clear regulatory cause with an uneven distribution of effect, rather than a claim that the Act alone explains any individual failure — rates, build costs and a soft new-build market press on the same companies.

Frequently asked questions
What does GalimAI's own data add here?
It attaches the liability to specific companies. GalimAI maps 463,022 property companies and 1M+ owners across England and Wales - including the freeholders, developers and management companies the Act made responsible - each linked to its directors, financing and distress signals, so you can see which owners are strained rather than reading a national progress table.
What did the Building Safety Act 2022 do?
It made building owners and original developers responsible for fixing unsafe cladding on buildings over 11 metres, backed by a legally-enforceable deal worth around 5 billion pounds, a developer tax and levy, and extended liability windows up to 30 years. It also created the Building Safety Regulator.
Where does the financial strain concentrate?
On freeholders and smaller developers who own one or a few affected buildings - they face the same fixed remediation cost and regulatory delay as the big builders but without diversified income to absorb it. GalimAI's distress signals surface these first.
How far has remediation got?
By January 2025, 96% of the 514 high-rise ACM buildings had started or completed remediation, but only 48% of the 5,025 buildings 11 metres-plus with unsafe cladding. A 2029 deadline now applies or landlords face penalties.
