Handing Back the Keys: Asbestos Accountability at Lease End

Lease endings are usually handled as a commercial and legal event: dilapidations, reinstatement, service charge reconciliation and the return of keys. Asbestos often sits outside that conversation until a contractor opens a ceiling or a buyer asks for the building file. By then, the window for a clean handover may have closed. This article sets out a practical approach for landlords and tenants who need to manage asbestos duties when a UK lease ends.

The duty follows control, not just the lease wording

Regulation 4 of the Control of Asbestos Regulations 2012 places the duty to manage asbestos in non-domestic premises on the dutyholder. In practice, that is usually the person who has responsibility for maintenance and repair, or who has control of the premises. In a single-let building, the tenant may hold that duty for the demised area while the landlord retains it for common parts. In a multi-let building, responsibilities can be split. At lease end, control may pass on surrender, expiry or the grant of a new lease. Contractual clauses can allocate cost and liability, but they do not automatically rewrite the statutory duty. The first step is therefore to establish who has control at each stage: during the final months of occupation, during any dilapidations works, and after handover.

Audit the inherited register before negotiating

A register that has not been updated since the last fit-out is a historical document. Tenants should obtain the current register, the survey reports, sample certificates, photographs and the management plan for the areas they occupy. Landlords should do the same for the areas they will receive back. Compare the register with the physical condition of the premises and with any alterations made during the term. Look for fit-out works, removed partitions, new ceilings, service penetrations and plant changes that may have disturbed or concealed ACMs. If the records are incomplete, treat the gaps as a finding rather than an administrative inconvenience. A joint inspection, recorded in writing, is often more useful than an exchange of emails after the event.

Read dilapidations and refurbishment clauses together

Dilapidations clauses often require the tenant to remove alterations, reinstate the premises or make good damage. Refurbishment clauses may require consent before alterations and may trigger survey or notification obligations. Read them together. A requirement to remove a partition is also a requirement to consider what is behind it and above it. If the exit works will disturb the fabric of the building, a refurbishment and demolition survey may be needed before work starts, and the Construction (Design and Management) Regulations 2015 may apply to the project. Removal of asbestos-containing materials is regulated work; it is not simply a line item in a dilapidations schedule. The handover should identify who is responsible for any removal, how it will be procured and what records will be passed on.

Do not assume the landlord's register covers the tenant's area

In multi-let buildings, the landlord's register may cover common parts and the building shell but not tenant alterations. A tenant's fit-out can introduce or disturb materials that never appear in the landlord's file. At lease end, the tenant should provide a record of any asbestos-related work, surveys or removals carried out in the demised area. The landlord should check that record against the building-wide register and update the management plan before the next occupier arrives. If the information cannot be established, the safe default is to presume the presence of asbestos until a competent survey says otherwise.

Document the transfer as a controlled handover

An email attachment is not a handover unless receipt and acceptance are recorded. Use a handover schedule that lists the register version, survey reports, sample results, photographs, drawings, action log and management plan. Record the date of transfer, the named recipient and any caveats. If limitations remain, state them plainly. If work is outstanding, identify who will complete it and by when. The aim is to leave the incoming dutyholder with a register they can use, not a box of files that requires a new survey to interpret.

Close the loop after the keys are returned

The lease event does not end when the keys are handed over. The incoming dutyholder should confirm that the register has been updated, that the management plan reflects the new occupation and that contractors have access to the current information. The outgoing party should retain its records for as long as they may be needed. A short post-handover review can identify missing certificates, unresolved recommendations or areas that were inaccessible at the time of survey. Neither party should inherit an unknown risk by omission. A clear transfer of asbestos information is part of a clean exit.
