Insurance and Debt Advisory Specialists

Our leadership team

Having spent more than 20 years working across the insurance and finance landscapes, J3’s leadership team witnessed first-hand the fragmented and sometimes, disconnected manner in which these two markets converge.

Setting out with the mission to bring finance and insurance together seamlessly, J3 was launched to fuse the two markets. Our aim is to enable property professionals to make better decisions, faster, while getting both the best finance and insurance solutions for their individual projects.

Why clients choose J3 Advisory


Keep it simple

We know arranging finance and insurance can be fragmented and sometimes challenging. So we make it simple. Finance and insurance are intrinsically linked, so by fully connecting the two, we enable property professionals to make better, more informed decisions. We use state-of-the-art technology to collect project information and then simplify the process by ensuring we truly understand our clients’ goals and objectives to find the perfect finance and insurance solutions.



While being results driven and providing a fresh approach we also offer the benefits of continuity. We frequently take care of the finance and insurance on multiple schemes with the same client, becoming an extension of our clients’ businesses. Clients benefit from our detailed knowledge of their projects, their objectives and a deepening relationship with their people. This evokes confidence not only from our clients but also the lenders and insurance underwriters we place business with.

By truly understanding your goals we can provide objective advice, finding you the best rates for your project and your business. We have access to all A-rated insurance providers and to lenders across the whole market. We offer a comprehensive market comparison to find you the most appropriate terms for your project, enabling you to make decisions confidently and swiftly.
