Eight years after Grenfell, thousands of residential blocks across England still have unsafe cladding on their walls. That single fact explains why Parliament introduced new legislation on 14 October 2026 and why the cladding remediation bill 2026 leaseholders have been waiting for is now moving through the Commons. For anyone buying, selling, or already living in a flat above 11 metres, this is not background political news. It directly affects mortgage approvals, service charges, and how quickly a sale can complete.
This article explains what the Bill and the new Building Safety Levy mean in practical terms, and what Prince Surveyors recommends checking before you commit to a purchase.
Key Takeaways
- The Building Safety (Remediation of Unsafe Cladding etc) Bill had its first reading on 14 October 2026 and still needs second reading and further stages before becoming law.
- It creates a legal duty on building owners to assess, plan, and fix life-critical cladding risks, backed by a new building register and criminal penalties for serious delays.
- Manufacturers of unsafe cladding products face easier legal claims, which could speed up funding for remediation works.
- The Building Safety Levy on new residential development started on 1 October 2026, adding a cost layer to new-build flats.
- Buyers of flats in 11m+ blocks should always check EWS1/FRAEW status, remediation plans, and leaseholder protection terms before exchanging contracts.
Why This Bill Exists
The Grenfell Tower fire killed 72 people. Since then, successive governments have tried various routes to force building owners to remove dangerous cladding, with mixed results. According to the National Housing Federation, thousands of buildings still have unsafe cladding today. The Remediation Acceleration Plan, announced in July 2025, promised firmer legal tools to speed things up. The Bill introduced in October 2026 is that promise taking legislative shape.
"Another important step" is how Kate Henderson, chief executive of the National Housing Federation, described the Bill, adding that the measures against manufacturers are "particularly important."
What the Cladding Remediation Bill 2026 Leaseholders Should Know Contains
The Bill is still subject to change as it passes through Parliament, but as drafted it includes several measures with direct relevance for leaseholders and buyers.
A Legal Duty to Fix Life-Critical Risks
"Responsible entities" for medium and high-rise residential buildings would have a clear legal duty to:
- Assess external wall fire safety risks
- Produce a remediation compliance plan
- Carry out remediation and mitigation works
- Keep life-critical risks under control throughout the process
A National Building Register
A register would be created covering all residential buildings between 11 and 18 metres in England. This closes a gap, since taller buildings already face more scrutiny under existing building safety rules.
Consistent Fire Risk Assessments
The Bill pushes for a standardised, audited approach to Fire Risk Assessments of External Walls (FRAEWs), replacing the inconsistent practices that have frustrated surveyors, lenders, and leaseholders for years.
Tougher Enforcement
Regulators would gain powers to act against building owners who delay remediation, including criminal prosecution in the most serious cases. As a last resort, a public authority could step in and carry out the remediation itself.
Easier Claims Against Manufacturers
This is arguably the most significant change for funding remediation. Under proposed amendments to section 149 of the Building Safety Act 2022:
- Claimants would need to show the cladding "caused, or contributed more than trivially to" the building being unfit for habitation.
- Manufacturers would be liable where they "engaged in misleading conduct."
- Parties who funded remediation, including developers, could bring claims to recover costs.
- Building Liability Orders would extend to these claims, allowing associated companies within a corporate group to be pursued.
- Claims would be resolved after remediation work is completed, so litigation cannot be used to stall urgent safety works.
- The Bill would commence two months after Royal Assent, with claims sitting within the existing 30-year limitation period.
Where the Bill Stands Now
As of October 2026, the Bill has only had its first reading. Second reading in the House of Commons is the next stage, followed by committee scrutiny, report stage, and the House of Lords process. This means the detailed provisions above could still be amended. No remediation deadlines or fine amounts have been specified in official sources, so treat any claims of fixed dates or penalty figures with caution until the Bill progresses further.
The Building Safety Levy: Already in Force
Separate from the Bill, the Building Safety Levy on new residential development in England took effect on 1 October 2026. This levy applies to new-build development and is designed to help fund building safety work, adding another cost consideration for developers that can feed through to pricing on new-build flats.
What This Means for Flat Buyers and Leaseholders
Checking a Flat's Cladding Status
Before making an offer on a flat in a block over 11 metres, always ask for:
| Document | Why It Matters |
|---|---|
| EWS1 form | Confirms external wall system fire risk status |
| FRAEW report | Details the fire risk assessment of external walls |
| Remediation compliance plan | Shows whether works are planned, funded, and scheduled |
| Building safety case | Required under the Building Safety Act 2022 for higher-risk buildings |
| Service charge accounts | Reveals any interim or historic remediation costs being passed to leaseholders |
How Lenders View Unremediated Buildings
Mortgage lenders remain cautious about blocks without clear fire safety documentation. A missing or unfavourable EWS1 or FRAEW can mean:
- Valuation down-valuing or refusal
- Mortgage offers withdrawn or delayed
- Reduced pool of buyers if you come to sell
This caution is unlikely to ease until remediation plans under the new Bill are clearly documented and verified.
Leaseholder Protections Already in Place
The Building Safety Act 2022 already gives many leaseholders protection from uncapped remediation costs, depending on the building's height, the leaseholder's circumstances, and who is liable. The new Bill does not replace these protections, it reinforces the pathway to actual remediation, which is what ultimately resolves the underlying risk and removes the uncertainty around future bills.
Service Charge Exposure
Even with leaseholder protections, interim measures such as waking watch, fire alarm upgrades, or insurance premium increases can appear on service charge demands. Buyers should always review at least two to three years of service charge accounts and ask the managing agent directly about any known remediation costs, pending or in progress.
Why a RICS Survey and Lease Review Matter More Than Ever
A standard mortgage valuation will not tell you enough about cladding risk, remediation funding, or legal exposure. A RICS Level 2 or Level 3 Home Survey, combined with a thorough review of the lease and management pack, gives buyers a much clearer picture of:
- The physical condition of the building, not just the flat
- Any visible signs of remediation work, scaffolding, or temporary fire safety measures
- Red flags in service charge accounts or building safety case documentation
- Whether the building appears on, or should appear on, the new residential building register
Prince Surveyors routinely flags these issues for clients buying in blocks affected by cladding concerns, helping buyers negotiate price, request further documentation, or walk away from unsuitable purchases before exchange.
Frequently Asked Questions
Has the cladding remediation bill 2026 leaseholders have been hearing about become law yet?
No. It had its first reading on 14 October 2026. It must still pass second reading, committee stage, report stage, and the House of Lords before receiving Royal Assent.
Does the Bill set a fixed remediation deadline?
No specific deadlines have been confirmed in the Bill as introduced. Any claims of fixed dates should be treated as unconfirmed until later stages of the legislative process.
What is the Building Safety Levy?
It is a charge on new residential development in England, in effect since 1 October 2026, intended to help fund building safety work.
Will the Bill help leaseholders claim against cladding manufacturers?
Yes, in principle. It proposes easier routes to hold manufacturers liable for misleading conduct relating to unsafe cladding products, and allows those who funded remediation to bring claims.
Should I still buy a flat in a block with unresolved cladding issues?
It depends on documentation, pricing, and lender appetite. A thorough survey and lease review can help you understand the real risk and negotiate accordingly rather than avoiding the market entirely.
How can Prince Surveyors help?
Prince Surveyors provides RICS Level 2 and Level 3 surveys alongside building safety documentation checks, giving buyers and leaseholders a clear, independent view before they commit to a purchase.
Conclusion
The cladding remediation bill 2026 leaseholders have been anticipating marks a genuine step toward resolving a problem that has lingered since 2017. It strengthens legal duties on building owners, creates a clearer register of at-risk buildings, and opens new routes to hold manufacturers accountable. But it is not yet law, and it will not instantly fix every building with unsafe cladding.
For buyers and leaseholders, the practical response is the same regardless of where the Bill ends up: get the documentation, understand the remediation status, and commission a proper survey before exchanging contracts. Contact Prince Surveyors to arrange a RICS Level 2 or Level 3 survey and a full review of your lease and building safety documentation before your next purchase or sale.
