Cladding Remediation Costs in 2026: What Leaseholders Actually Have to Pay

The Post-Grenfell Legal Framework

Following the Grenfell Tower fire, the government introduced sweeping reforms through the Building Safety Act 2022, aimed at stopping the cost of fixing unsafe cladding and other fire safety defects from landing on the leaseholders who live in affected buildings — often people who had no role in choosing the original building materials or design.

The core protections apply to "relevant buildings" — broadly, self-contained residential buildings in England at least 11 metres tall or with five or more storeys — where a defect was caused during construction or refurbishment work carried out (or arranged) by the freeholder, developer, or an associated party.

What Leaseholders Are Protected From

The non-cladding defect caps broadly work on a sliding scale — properties in London have different (generally higher) caps than the rest of England, and very low-value flats can be exempt from contributing to non-cladding costs entirely. The specific cap amounts are set out in regulations under the Act and should be confirmed against current gov.uk guidance for your property's value band, since detailed figures are updated periodically.

Who Isn't Fully Protected

The protections are not universal. Key exceptions to be aware of:

• Leaseholders who own three or more UK residential properties (in addition to their main home) have reduced statutory protection and may face uncapped liability in some circumstances.
• Buy-to-let landlords with larger portfolios fall into this reduced-protection category.
• Buildings under 11 metres are outside the main statutory protection regime, though separate advice and, in some cases, funding routes may still apply depending on risk assessment.
• Commercial freeholders that have gone into insolvency with no traceable developer can complicate and slow down (though not usually eliminate) access to remediation funding.

The Building Safety Fund and Cladding Safety Scheme

Where a developer cannot be identified, has ceased trading, or refuses to pay, the government's funding schemes are designed as a backstop:

• Building Safety Fund — funds removal of unsafe cladding on eligible buildings 18 metres and above (originally), with eligibility criteria evolving over time
• Cladding Safety Scheme — extended funding to eligible buildings between 11 and 18 metres

Applications are made by the building owner or managing agent, not by individual leaseholders directly — if you're a leaseholder, your first step is asking your freeholder or managing agent about the building's application status, not applying yourself.

Checking Your Building's Status

1. Ask your freeholder or managing agent directly for the building's remediation status and whether a Building Safety Fund/Cladding Safety Scheme application is active or complete.
2. Request a Leaseholder Deed of Certificate, which formally confirms your protected status under the Act, including your qualifying lease status and any contribution cap that applies to you.
3. Check whether the building's developer has signed the government's Building Safety Pledge, committing to fund remediation without leaseholder contributions.
4. If buying or remortgaging, ask your solicitor to specifically check remediation status and whether an EWS1 form (or updated equivalent assessment) is required by the lender.

Practical Implications for Buying, Selling and Remortgaging

Even with strong statutory protections in place, unresolved remediation status can still cause serious practical problems:

• Mortgage lenders may be cautious about buildings without confirmed remediation completion or a valid EWS1/PEFA assessment, even where the leaseholder themselves owes nothing
• Marketability can be reduced — some buyers and their lenders will avoid affected buildings until remediation is complete
• Service charges may still rise to cover interim safety measures (such as a waking watch) while remediation is pending, even if the leaseholder isn't liable for the remediation cost itself

Anyone buying a flat in a building constructed or clad after the mid-1990s in a taller residential block should specifically ask about fire safety and remediation status as part of conveyancing, regardless of statutory protections, simply because of the practical impact on future sale and mortgage prospects.
