LBB delivers major cost saving warranty advice on complex 743-unit mixed-use scheme
Protecting developments today. Powering the communities of tomorrow.
Project Overview
Developer: Berkeley Homes (Southall)
Location: The Green Quarter, Southall
Development: New-build, mixed-use 11-block apartment scheme comprising 743 homes across Private Sale, BTR, Social Housing, and Commercial tenures.
LBB Lead: Rachel Bryant, Account Director
LBB recently advised Berkeley Homes (Southall) on the placement of structural warranty cover for Phase 2 East of The Green Quarter in Southall, a major mixed-use development comprising 743 homes across 11 blocks. The transaction highlights LBB’s ability to unlock competitive market solutions for highly complex, large-scale urban regeneration schemes.
Led by Rachel Bryant, Account Director at LBB, the project required a flexible warranty solution capable of addressing significant legacy construction and interface risks. Phase 2 East presented a complex risk profile due to a shared basement running beneath earlier phases completed under different warranty providers. Historically, the region relied on restrictive warranty norms, which limited the client’s ability to compare broader market options.
By introducing a suitable, value-add provider, Rachel achieved a cost saving of over £1m, and ensured that cover was sufficient. LBB has been advocating for better awareness around underinsurance and the risks of capped policies that don’t fully cover the reinstatement value of the project.
To break through these regional constraints and manage the unique structural overlaps, Berkeley required a partner who could deliver:
-
Technical Pragmatism: An underwriter willing to take a practical, risk-managed view of the shared basement arrangement.
-
Full Reinstatement Cover: Securing comprehensive, full reinstatement value cover on a highly non-standard risk.
-
Institutional Credibility: Strong balance-sheet backing and reputational comfort to satisfy long-term stakeholders.
-
Cash-Flow Efficiency: A deferred payment structure, with the majority of the premium payable at Practical Completion.
Drawing on LBB’s longstanding relationship with Berkeley, Rachel Bryant introduced the scheme to a wider panel of warranty providers, enabling a full-market comparison for the first time on this project. Following detailed technical and commercial engagement, BLP Insurance was selected as the optimal partner. BLP demonstrated a clear willingness to underwrite the shared basement arrangement and interface risks with previous phases, standing out through very favourable technical terms despite the inherent complexity of the scheme.
The final placement secured full reinstatement value cover at a highly competitive price, with the reassurance of tier-one Aviva backing to provide critical long-term comfort for the client. Crucially, LBB structured the agreement so that the majority of the premium is deferred until Practical Completion, significantly supporting the project’s ongoing cash flow.
By leveraging LBB’s market access and technical expertise, Berkeley Homes benefited from:
-
Expanded Market Access: Moving beyond legacy regional norms to introduce genuine market competition.
-
Streamlined Procurement: A clear, evidence-based breakdown of technical cover, pricing, and payment structures.
-
Complex Risk Resolution: Facilitating meaningful insurer engagement to secure full reinstatement cover on terms previously considered difficult to obtain.
-
Optimised Financial Structures: Achieving significant cost savings versus traditional incumbent providers alongside cash-flow-efficient deferred payments.
This transaction highlights how active market engagement and rigorous technical negotiation can unlock improved commercial outcomes on the UK’s most ambitious, phased urban developments. By addressing complex structural challenges head-on, LBB enabled Berkeley to secure robust, institutionally credible warranty protection that ensures long-term certainty for this landmark 743-home community.
