£2.3 Billion: The True Cost of BSA Compliance

£2.3 billion. That's what Building Safety Act compliance has cost UK landlords collectively to date. Cladding remediation, fire safety improvements, safety case preparation, professional fees, and the army of consultants, lawyers, and specialists that the Act has spawned.

And we're not done. The BSR's enforcement acceleration in Q1 2026 signals that the next wave of compliance spending is about to begin — targeting the buildings that have been hoping the problem would go away.

Where the £2.3 Billion Went

• Cladding remediation: £1.4 billion — the largest single category, covering ACM and non-ACM cladding removal and replacement
• Fire safety improvements: £420 million — fire doors, compartmentation, detection systems, sprinkler retrofits
• Safety case preparation: £180 million — consultancy fees for preparing the safety case reports the BSR requires
• Professional and legal fees: £300 million — building surveyors, fire engineers, lawyers, and the specialists needed to navigate the Act's requirements

What's Still to Come

The £2.3 billion covers the buildings that have already acted. The BSR's data suggests that a significant proportion of in-scope buildings haven't started their compliance journey. Conservative estimates put the total eventual BSA compliance cost at £4-5 billion when all buildings have been addressed.

Who's Paying

The political narrative was that developers would pay. In practice, costs are split across building owners (who bear the upfront cost), leaseholders (through service charges for non-cladding works), and taxpayers (through the Building Safety Fund for qualifying cladding remediation). The allocation is contentious, legally complex, and varies building by building.

Frequently Asked Questions

Can leaseholders be charged for BSA compliance work?

For cladding remediation in qualifying buildings, leaseholder contributions are capped. For non-cladding fire safety works, costs can be passed through service charges but are subject to reasonableness challenges. The legal landscape is still evolving.

Is government funding available for BSA compliance?

The Building Safety Fund covers ACM cladding remediation for residential buildings over 18m. The Cladding Safety Scheme covers non-ACM cladding. Other fire safety improvements are typically unfunded. Check eligibility criteria carefully — the funds have specific qualifying conditions.
