Triggers for Serving the Deed of Certificate
Under Regulation 6 of the Building Safety (Leaseholder Protections) (England) Regulations 2022, a leaseholder can serve a Deed of Certificate on their landlord at any time.
However, serving the certificate becomes urgent under three specific legal triggers:
1. Notice from Landlord: When the landlord serves a formal notice stating remediation works are required, the leaseholder has exactly 2 calendar months to return the completed Deed of Certificate.
2. Sale of the Property: When selling the flat, the buyer's conveyancer and mortgage lender require the certificate to establish that the buyer will inherit £0 cladding liability.
3. Transfer or Assignment: Whenever the lease is formally assigned to a new legal proprietor.
If a leaseholder fails to return the Deed of Certificate within the statutory 2-month window (or any 14-day reminder notice), the lease is legally deemed 'non-qualifying'. All statutory protections are forfeited, exposing the owner to uncapped repair bills.
Required Supporting Evidence to Attach to the Deed
A completed Deed of Certificate must be accompanied by verified evidence proving status as of 14 February 2022:
• Principal Residence Proof: Utility bills, bank statements, or electoral roll records dated between November 2021 and February 2022, or a copy of the Council Tax bill for the 2021/2022 tax year.
• Property Portfolio Proof: If the flat was not the principal home, title deeds proving the owner held 3 or fewer UK residential properties on 14 February 2022.
• Purchase Price Evidence: A copy of the historical completion statement or Land Registry price paid register if the flat was acquired within 12 months preceding 14 February 2022.
The Landlord's Reciprocal Obligation: The Landlord Certificate
Within 4 weeks of receiving the Leaseholder Deed of Certificate (or when demanding service charges for building defects), the landlord must issue a Landlord Certificate under Regulation 7.
The Landlord Certificate discloses: (1) Whether the current landlord or developer group was responsible for the defects, (2) The landlord's net wealth (the 'developer test' and 'landlord net wealth test' of over £2m per building), and (3) What historical costs are lawfully recoverable from leaseholders. If the landlord fails to provide this certificate within 4 weeks, they are legally barred from recovering ANY defect costs.
