The Building Safety Act and much of its associated secondary legislation came into force in October 2023. Since then, it has become increasingly clear that the construction industry faces significant challenges in complying with the new legislation. For buildings that are 11 metres high or have 5 storeys (and contain at least two dwellings), the Building Safety Act 2022 provides that accountable persons, which include landlords and management companies, may in some circumstances be able to pass on remediation costs to leaseholders. Whether a leaseholder has a qualifying lease or non-qualifying lease will determine if they are liable for building safety remedial costs.
As the remedial works can at times be very costly, it is vitally important for leaseholders to know whether they will be responsible for such costs. And, if they are responsible, how much, which costs, and to what extent, is further dependent on whether a lease is qualified or not.

What is classed as a qualifying lease?
A lease is a qualifying lease under BSA 2022 where it is a long lease of a single-dwelling, under which the leaseholder is required to pay a service charge and which was granted before 14 February 2022 and, as of at that date, was either the leaseholder’s home, or the leaseholder owned no more than 2 additional dwellings in the UK.
The new law created legal protections for qualifying leaseholders from historical building safety costs. There is also a limit of the costs that the building owner could recoup from the leaseholder. There is also a limit of the costs that the building owner could recoup from the leaseholder.
Since 26 December 2023, a lease extension will not automatically cause a leaseholder to lose qualifying status. Where a qualifying lease is replaced by a new lease on substantially the same terms (a “connected replacement lease”), the new lease can itself be treated as qualifying, provided the relevant conditions are met.

Cladding related remediation work
Government cladding funds
The government has a comprehensive plan for the removal of an unsafe cladding system on all buildings above 11 metres. Where the developer of a building above 11 metres cannot be identified or held responsible, funding will be made available through the Cladding Safety Scheme.
The scheme is being delivered by Homes England and is open for applications for buildings between 11-18 metres in London and buildings over 11m in the rest of England, where a responsible developer cannot be identified, traced, or held responsible.
Leaseholder
- Qualifying lease – no claim for costs can be made against the leaseholder;
- Non qualifying lease – if no government cladding fund is available and no manufacturer is available, the leaseholder will have to bear the costs.

Developer
Most major developers and housebuilders have agreed to fix “life-critical fire safety defects” and have entered into developer remediation contract with government. You can check the link below for more information.

Landlord
Landlords which are associated with the developer of the building, being part of the same group or owned directly or indirectly by the developer or vice versa, no claim for costs can be made against tenants.
- In other circumstances, landlord will also not be able to claim remediation cost from qualifying leaseholder if it has a group net worth of over £2 million times the number of relevant buildings in the landlord’s group.
The landlord must provide a Landlord certificate when they want to pass on part of the cost of remediation onto leaseholder, through the service charge or within 4 weeks of leaseholder requesting a landlord’s certificate.
Since 24 July 2024, there is a limited exception to this protection: a Right to Manage company or resident management company can apply to the court for a Remediation Contribution Order to split certain litigation costs among leaseholders.
Leaseholders
Qualifying lease
How much building owners can recoup from the leaseholder depends on the value of the relevant lease. If it is below £175,000 outside London, or £325,000 within London, no costs can be recouped from the leaseholder. If it is not less than £175,000 outside London or £325,000 in London, but does not exceed £1,000,000, any contribution by the leaseholder will be capped at £10,000 outside London or £15,000 in London.
However, if the property value exceeds £1,000,000 but does not exceed £2,000,000, any contribution by the leaseholder is capped at £50,000. If it exceeds £2,000,000, any contribution by the leaseholder will be capped at £100,000.
In the meantime, any remedial contribution by the leaseholder must be spread evenly over 10 years, hence a maximum of £10,000 a year.
Non-qualifying lease
The landlord can claim cost without limit from leaseholder in relation to any remediation works.
It should be noted that the Building Safety Act 2022 only applies to properties constructed from 28/06/1992 to 27/06/2022 or any subsequent work to remedy the historic defects originated from this period of time. For any building which is completed after 27/06/2022, it is expected that they should have met all the relevant safety requirements and hence be free from such risks.
