How the Building Safety Act Affects Leaseholders

Leaseholder protections under the Building Safety Act 2022: who qualifies, what costs are capped and what it means for selling and buying flats in affected buildings.

Overview

Leaseholder protections explained

The Building Safety Act 2022 introduced comprehensive protections for leaseholders in buildings with fire safety defects. These protections determine who pays for remediation and cap the amounts that qualifying leaseholders can be charged. Understanding your status under the Act is essential if you own a flat in a building affected by cladding or fire safety issues.

Qualifying vs non-qualifying leaseholders

The Act distinguishes between qualifying and non-qualifying leaseholders. A qualifying leaseholder is one who owned the lease on 14 February 2022 and either occupied the flat as their main home or owned no more than three UK residential properties. Qualifying leaseholders benefit from cost protections; non-qualifying leaseholders (those with larger property portfolios) do not.

Cost caps and protections

For qualifying leaseholders, the Act establishes a hierarchy of liability. First, the developer or original builder must pay if they can be identified and are solvent. Second, the freeholder must pay if they are linked to the developer. Only where neither of these can be made to pay do leaseholder contributions come into play, and even then they are subject to caps: £15,000 in London for non-cladding defects in buildings over 18 metres, with lower caps for smaller buildings and outside London. For cladding defects specifically in buildings over 18 metres, qualifying leaseholders pay nothing.

Impact on the market

The protections have significantly improved the position for leaseholders in affected buildings. EWS1 certificates provide the standardised assessment that lenders require, and the combination of government funding schemes and leaseholder protections has restored confidence in many buildings that were previously unmortgageable. However, buildings with unresolved issues may still face lending and insurance difficulties until a clear remediation pathway is established.

FAQ

Frequently asked questions

What is a qualifying leaseholder?

A leaseholder who owned the lease on 14 February 2022 and either occupies it as their main home or owned no more than three UK residential properties. They benefit from cost protections for remediation.

What costs are leaseholders protected from?

Remediation of cladding and fire safety defects, associated professional fees, and temporary safety measures. Non-qualifying leaseholders do not benefit from these protections.

Are there caps on leaseholder charges?

Yes. In London: £15,000 for non-cladding defects in buildings over 18m, £10,000 for 11-18m buildings. For cladding defects in buildings over 18m, qualifying leaseholders pay nothing.

How does this affect selling a flat?

The protections and EWS1 process have improved lending confidence. Buildings with clear remediation pathways are more readily mortgageable, though unresolved issues may still cause difficulties.
