How to Handle a BTL Flat With Cladding Issues

Introduction

Cladding remediation has been the defining BTL crisis of the post-Grenfell decade. The Building Safety Act 2022 brought meaningful protections — but explicitly excluded landlord portfolios from the most generous of them. Here's where you stand in 2026.

EWS1 form

External Wall System form, introduced 2019. Rates the external walls A1 (no combustible materials, no action), A2 (compliant materials, no action), B1 (combustible but acceptable), or B2 (combustible, remediation required). Mortgage lenders typically need A1, A2 or B1. B2 is mortgage-blocking until works complete.

Building Safety Act 2022 — qualifying leases

Leases qualifying for full protection: owned on 14 February 2022, building 11m+ or 5 storeys+, owner's principal home OR owner had 3 or fewer UK properties total at qualifying date. Qualifying leases pay £0 for cladding and a capped service charge contribution to non-cladding fire safety works (£10,000 outside London, £15,000 inside).

Why BTL portfolios are excluded

The qualifying threshold of 'three or fewer UK properties' deliberately excludes professional landlords. Most portfolio landlords have 4+ properties and lose statutory protection — exposing them to the full remediation cost (sometimes £50,000–£150,000 per flat).

Developer Remediation Contract

150+ major housebuilders signed up — Barratt, Persimmon, Taylor Wimpey, Berkeley, etc. Covers cladding and other fire safety defects on buildings 11m+ they developed since 1992. Landlord cost in scope: £0 even for non-qualifying leases. Check via the government's Building Safety Portal.

Building Safety Fund and Cladding Safety Scheme

Government-funded for buildings 11m+ where developer can't pay. Covers cladding remediation only (not other fire safety works). Application by responsible person (usually freeholder/RMC). Non-qualifying leaseholders contribute to non-cladding works subject to the cap (where eligible) or full cost (where not).

Selling a stranded flat

Buyers are scarce; cash buyers dominate. Typical discount 30–60% off pre-2017 vacant possession. Specialist buyers (Open Property Group, Cladding Buyers, We Buy Any Home) make low-ball cash offers. Selling to other portfolio landlords is harder than ever — protect yourself with full disclosure to avoid misrepresentation claims.

Renting it out

Cladding doesn't stop you letting unless a Prohibition Order is in force. Building insurance premiums on tall cladded buildings have risen 5–10x — these costs flow through service charges. Tenant disclosure best practice: confirm the building's fire safety status in writing before tenancy.

The wait

Most cladding remediation programmes complete 2027–2030. Sales market will gradually unfreeze as buildings get clean EWS1 certificates. Holding through the remediation period — uncomfortable as it is — usually recovers value better than fire-sale exit.
