J3 Advisory
About Us
Independent advice on structural warranties, transactional risk and property finance
J3 Advisory advises developers, lenders, investors and professional teams on the insurance, risk and funding considerations that shape successful property development. Our expertise spans structural warranties, latent defects insurance, legal indemnities, transactional risk and structured property finance, helping clients make informed decisions from early planning and funding through to practical completion, refinancing and exit.
Insurance is rarely an isolated decision. A structural warranty can influence lender requirements, funding and project delivery, while legal risk and finance often need to be considered alongside technical information. Our role is to understand those relationships early, helping clients make informed decisions that support both programme and commercial objectives.
Every development is different. Rather than recommending products, we advise on the most appropriate strategy for the project, taking account of its technical requirements, funding structure and commercial objectives.
We work with developers, lenders, investors, housing associations, contractors, insolvency practitioners, receivers and professional advisers across residential, Build to Rent (BTR), Purpose-Built Student Accommodation (PBSA), commercial and mixed-use developments. Our experience includes projects involving Cain International, Fusion and HG Construction, where insurance formed part of wider funding, technical and delivery considerations.
Alongside new developments, we regularly advise on part-complete, distressed and receivership projects, helping clients review existing technical information, secure appropriate insurance solutions and support refinancing, completion or disposal strategies where certainty is critical.
Whether arranging a structural warranty, advising on transactional risk or supporting a development finance instruction, our objective remains the same: to provide clear, independent advice that helps clients reduce execution risk, maintain momentum and deliver projects with confidence.

Why we exist
J3’s role is to support sound decision-making across complex real estate transactions.
Property development rarely depends on a single decision. Structural warranties, latent defects insurance, legal indemnities and funding are often considered separately, yet each can influence lender requirements, project delivery, refinancing and ultimately the successful completion of a development. Bringing those disciplines together earlier helps reduce uncertainty and gives clients greater confidence in the decisions they make throughout the project lifecycle.
J3 Advisory exists to provide that joined-up advice. By understanding how insurance, technical requirements and funding interact, we help developers, lenders and investors make informed decisions from the earliest stages of a project through to practical completion, refinancing and exit. Our advice is independent, commercially focused and shaped by real project experience, ensuring insurance supports the wider objectives of the development rather than becoming an obstacle to delivery.
Our Role
Where insurance, funding and technical risk need to work together.
Clients engage J3 at different stages of the development lifecycle. Some appoint us during the planning and funding stages, where early advice on structural warranties, insurance strategy and lender requirements can help inform key project decisions before construction begins. Others require support during construction, coordinating technical information, managing underwriting requirements and keeping projects progressing towards practical completion.
Our involvement doesn’t end when a policy is placed. We continue working alongside developers, contractors, surveyors, insurers and lenders throughout the build, helping manage technical queries, coordinate inspections and support the warranty through to issuance. Whether acting on a straightforward residential scheme or a complex refinancing, our objective remains the same: to provide practical advice that helps projects progress with confidence.
