You bought a flat to live in. It is your only home. Now you discover that your protection from certain historical building-safety costs may depend on the circumstances of someone who owned it before you.
For a buyer, that can be difficult to understand. Why should the previous owner’s property portfolio affect the financial risks attached to your home?
The government has recognised this problem in proposals announced on 27 October 2026. For owners already facing questions about costs, selling or remortgaging, the announcement also brings the original purchase advice into focus: what was established about the lease’s status, and what were you told?
The qualifying date can matter more than your purchase date
Under the Building Safety Act 2022 leaseholder cost-protection framework in England, qualifying status depends on statutory conditions, including circumstances at the beginning of 14 February 2022.
The tests address the lease, building and ownership circumstances. Among the ownership conditions, the dwelling could qualify where it was the relevant owner’s only or main home, or where that owner held no more than three UK dwellings in total at the qualifying time.
A later buyer does not simply establish qualifying status by moving into the flat as their only home. The lease’s existing status can pass to subsequent purchasers.
The government’s guidance on qualifying leases and the qualifying date explains the framework. The complete tests and supporting evidence need assessment for the particular property.
A buyer discovered the issue before completing
In a HousingUK discussion posted on 13 December 2023, a prospective purchaser described finding a London flat they wanted to buy.
The buyer reported that their solicitor had identified a non-qualifying lease because of the seller’s circumstances, including ownership of multiple properties. They were concerned about inheriting that position.
They also described the building as currently safety compliant, with no cladding issues requiring rectification. That left them weighing the uncertainty of possible future costs against their wish to proceed.
This is an anonymous account of a proposed purchase, not a verified assessment of the building or evidence that the transaction completed. It illustrates the decision a buyer can face even where no substantial remediation bill has yet been identified.
What has the government proposed?
The government announcement of 27 October 2026 identifies later purchasers who miss out on cost protections because of a previous owner’s circumstances.
It says the government is exploring how to narrow that gap. It also announces an intention to increase the relevant property-ownership limit from three to six and support for certain collectively owned and enfranchised buildings.
These are different proposed responses to gaps in protection. They should not be combined into an assurance that every affected leaseholder is now protected.
In particular, an announcement about a future ownership threshold does not itself establish the status of your lease, remove an existing demand or satisfy a mortgage lender. Obtain advice on the rules and arrangements actually applicable to your property.
Non-qualifying does not mean every bill is yours
Non-qualifying status requires careful investigation, but it should not be translated into a blanket statement that the owner must pay every building-safety cost.
Other protections and funding arrangements may apply. Government guidance explains that the developer test can protect qualifying and non-qualifying leaseholders where the statutory conditions are met.
Developer commitments and remediation funding may also be relevant. Establish the particular defects, works and costs covered, rather than relying on a general statement that the building is funded.
The government’s guidance on remediation costs explains the distinctions. The lease, statutory restrictions and actual funding arrangements need to be considered together.
A satisfactory safety document answers a different question
An EWS1, fire-risk assessment or other technical report may provide information relevant to the building’s condition or a lender’s valuation requirements.
It does not, by itself, determine the lease’s qualifying status or who must pay for particular works.
Likewise, the absence of planned works is relevant information, but it is not a guarantee that no defect will be identified or expenditure proposed later.
Our article on selling a flat after cladding remediation explains why funding, completed works and mortgage acceptance need separate answers.
Why can this affect a sale or remortgage?
A prospective buyer may want to understand the potential financial exposure before committing. Their conveyancer may need certificates, supporting information and clarification of the available protections.
The proposed mortgage lender may also have requirements concerning the building, lease and evidence supplied. Acceptance by the lender involved in an earlier purchase does not establish what another lender will require now.
Before describing the flat as unmortgageable, identify the actual outstanding issue. Is it missing documentation, an identified cost, uncertainty about protection or a particular lender’s instruction?
Our broader guide to cladding, EWS1 and building-safety problems when selling considers those transaction questions.
What was established when you bought?
If you bought after the statutory protections became relevant, the original file may help show whether the lease’s status was investigated and explained.
Useful records can include:
- The lease and title documents.
- Any leaseholder deed of certificate and supporting evidence.
- Any landlord’s certificate and related correspondence.
- The management pack and replies to building-safety enquiries.
- Information about known defects, proposed works and funding.
- The Report on Title and other advice given before exchange.
- Reports to the mortgage lender and its responses.
A missing document and a confirmed non-qualifying lease are different findings. Establish what the available evidence actually demonstrates and what remains unresolved.
If you purchased before the protections existed, the investigation must reflect that earlier legal and factual context. Today’s certificate requirements should not simply be applied retrospectively.
Was the status recorded or its significance explained?
A report may use the expression “non-qualifying lease”. The question is what explanation accompanied it.
Were you told why that conclusion had been reached? Were the potential consequences, available protections and outstanding uncertainties explained? Were you advised to obtain further information or specialist advice before committing?
The significance also depends on what was known about the building at the time. A transaction involving identified defects and substantial proposed expenditure raises different questions from one where no such issue had been disclosed.
Our article on a signed Report on Title and client understanding considers why receiving a document does not, by itself, settle whether a material risk was adequately explained.
A proposed reform does not establish an earlier mistake
The government’s recognition of a gap does not prove that the original conveyancer failed in their duties. Nor does a later demand, mortgage difficulty or buyer’s concern establish negligence.
The relevant questions concern the retainer, purchase date, information available, enquiries made and advice actually given.
Where mortgage instructions are relevant, obtain the historical wording for the appropriate dates rather than assuming today’s requirements applied. The lender’s instructions and the advice owed to the purchaser are related but separate questions.
Keep the immediate problem moving while gathering those records. Obtain advice about any payment demand, transaction deadline or applicable legal time limit.
