Buildings monitored with unsafe cladding
Government data · May 2026
Cladding remediation tracker
See how remediation of unsafe cladding is progressing nationally and in reporting local authorities, using a transparent snapshot of MHCLG’s latest monthly release.
National position
Remediation status across England
“Completed” can include buildings awaiting building-control sign-off. “Not started” means works have not begun, even where a building has entered a programme or has plans.
1,672 completed
659 underway
2,080 not started
are estimated to be in monitored buildings where remediation had not started at the data date.
Programme comparison
Progress differs sharply by remediation route
Programme rows overlap and use different eligibility and reporting rules, so they must not be added together. Each bar compares status only within that row.
ACM programme
516 buildings- Complete
- 91%
- Underway
- 5%
- Not started
- 4%
High-rise buildings with unsafe ACM; completion includes awaiting sign-off.
Building Safety Fund
640 buildings- Complete
- 75%
- Underway
- 12%
- Not started
- 13%
Eligible high-rise non-ACM buildings proceeding with an application.
Cladding Safety Scheme
1,325 buildings- Complete
- 8%
- Underway
- 19%
- Not started
- 73%
Eligible 11m+ buildings; separate pre-eligible applications are not included here.
Developer cladding defects
1,815 buildings- Complete
- 31%
- Underway
- 16%
- Not started
- 53%
Developer-reported buildings with cladding defects; overlaps with other programmes can occur.
Beyond the monitored total
The identified portfolio is not the whole problem
Government estimates and management information describe different aspects of the remediation challenge and use different reference dates.
Residential buildings 11m+ estimated to have or have had unsafe cladding, March 2026.
Estimated share of buildings expected to enter government programmes that was being monitored.
March 2025 estimate; it has not yet been updated for the March 2026 building estimate.
11m+ buildings with suspected unsafe cladding subject to local-authority Housing Act action as at 22 May 2026.
Regional comparison
Completed-remediation rate by region
Regional percentages are rounded and describe the monitored portfolio, not every residential building in the region.
How to read the tracker
Coverage and limitations matter
It is programme monitoring data
The figures combine ACM remediation, the Building Safety Fund, Cladding Safety Scheme, developer-led remediation and social-provider self-funded work while accounting for known overlap.
It is not an individual-building register
Local counts are banded. The tracker cannot tell a leaseholder whether their particular block is safe, funded or complete.
The methodology changed
From April 2026, developers report cladding and non-cladding work separately. That improved accuracy but reduced direct comparability with earlier totals.
Completion needs context
Government totals can include completed work awaiting building-control sign-off. Building owners should retain scheme, design, completion and FRA evidence for their own block.
For responsible persons
Manage fire risk while remediation is planned or underway
Remediation status does not suspend Fire Safety Order or Building Safety Act duties. The responsible and accountable persons should keep the external-wall evidence, FRA, safety case and interim arrangements aligned as information and site conditions change.
- Record the external-wall evidence and specialist limitations
- Review the FRA when risk information, evacuation strategy or work changes
- Control temporary fire loads, access, alarms and escape routes during work
- Communicate proportionately with residents
- Keep completion, commissioning and building-control records
Frequently asked questions
Cladding remediation tracker FAQs
Does this tracker list individual buildings?
No. The government publishes aggregate programme and local-authority data. Local building counts are banded where necessary to avoid identifying individual blocks.
Does completed remediation mean building control has signed off the work?
Not always. The government completed category can include buildings awaiting building-control sign-off. Check the building’s own records for its exact status.
Why can totals change between releases?
Buildings enter, leave or transfer between programmes, duplicated records are reconciled and reporting methods change. April 2026 introduced separate developer reporting for cladding and non-cladding defects, affecting comparisons.
Is every unsafe-cladding building in this dataset?
No. It covers buildings monitored through specified government programmes and reporting routes. The department estimates that more buildings require remediation than are currently monitored.
Does remediation replace the fire risk assessment?
No. The responsible person must keep the FRA current, consider the external wall and manage interim precautions and other fire-safety risks throughout the works.
