The Legal Mechanism: Section 119 and Lease-Based Status
When the Building Safety Act 2022 was drafted, Parliament introduced Section 119 to create a static historical assessment. Section 119(2) defines a 'qualifying lease' based entirely on criteria satisfied on a single fixed date: 14 February 2022.
Because the statute defines the lease rather than the individual, the Court of Appeal and government guidance confirm that statutory protection transfers with the legal title upon assignment, probate, or sale. The personal circumstances of the purchaser do not alter, diminish, or extinguish the statutory caps.
Many landlords mistakenly assume that because they own more than 3 rental properties, they cannot purchase a protected flat. If the vendor's lease was qualifying on 14 February 2022, the investor receives the exact same statutory £0 cladding shield.
The Non-Qualifying Trap: Why Non-Qualifying Leases Never Heal
The static nature of the 14 February 2022 date cuts both ways. If a flat was owned by a commercial landlord with 4 or more residential properties on 14 February 2022, that lease is classified as 'non-qualifying'.
Crucially, even if that non-qualifying flat is later purchased by a first-time buyer who will occupy it as their sole principal residence, the lease remains permanently non-qualifying under current English law. The purchaser remains liable for uncapped service charges for building safety defects, making comprehensive conveyancing pre-contract enquiries essential.
| Status on 14 Feb 2022 | Purchaser Type | Protection Transferred? | Remediation Cost Exposure |
|---|---|---|---|
| Qualifying (Sole Home) | First-time Buyer | Yes (Full) | £0 cladding; max £10k/£15k non-cladding |
| Qualifying (1-3 Properties) | Portfolio BTL Investor (10+ properties) | Yes (Full) | £0 cladding; max £10k/£15k non-cladding |
| Non-Qualifying (4+ Properties) | First-time Buyer | No (Never heals) | Uncapped remediation liability |
| Non-Qualifying (Commercial Owner) | Owner-occupier | No (Never heals) | Uncapped remediation liability |
Buyer Due Diligence: What Conveyancers Must Inspect
Conveyancing solicitors must ensure that the vendor provides both a fully executed Leaseholder Deed of Certificate (including contemporaneous council tax or utility bills from February 2022) and a Landlord's Certificate.
If the seller failed to return the Deed of Certificate within the landlord's statutory 8-week window, the buyer's solicitor must demand proof that the landlord has not recorded the lease as non-qualifying under Regulation 6(7). Without these documents in order, mainstream lenders will decline mortgage drawdown.
