Matthew Roper
MRICS Director,
Development and Construction Risk
Property development lender
J3 Advisory has been a valuable specialist resource to Shawbrook across a number of areas relating to development risk.
The team has provided practical guidance around general insurance requirements, helping us consider the structure and level of cover we should request.
We have also worked with J3 in relation to structural warranty and latent defects insurance matters, where their specialist knowledge and understanding of lender requirements has helped navigate more complex cases.
We have found the team knowledgeable, pragmatic and commercially minded, with a strong understanding of both the insurance market and the requirements of development lenders.
Dan Bryant, Director
Tier 1 construction contractor
I’ve used J3 for a number of years and have always found them to be extremely helpful, professional and responsive. If we’re working with a new client, we would always recommend they speak to the guys at J3.
Their quick quote service is particularly useful at the outset, giving us an early indication of cost and helping us get things moving quickly.
What I particularly value is that they understand the practical side of delivering a project and stay involved throughout. If issues arise, they’re always available to help us work through them and keep things moving.
I wouldn’t hesitate to recommend Jack, Johnny and the team.
Tom Brown
Director
Real estate development lender
I’ve known Jack for a number of years and have watched J3 develop from a specialist business into a team we increasingly rely on when transactions become more complicated.
From a lender’s perspective, identifying a problem is only part of the job. What matters is understanding what it means for the transaction, providing a clear view and then helping the parties find a sensible way through it. J3 are very good at that.
We’ve worked with them on straightforward development matters, but also in situations where projects became distressed and existing insurance & warranty arrangements have needed to be unpicked and resolved. They understand the commercial realities, deal well with borrowers and other advisers, and importantly, stay involved until the issue is actually resolved.
I’ve also watched Jack build the business and the team around him. There is a strong culture at J3, good people and a genuine depth of specialist knowledge. I trust their judgement and I’m always very comfortable introducing them into a situation where I think they can add value.
Emma Burke
Director
Property development lender
I’ve worked with Jack and J3 for a number of years on a range of development transactions and specialist issues.
They understand the lender side of a deal and, importantly, they know when something that looks small can become a much bigger problem. They’re commercial, they give you a straight answer and they don’t disappear once the issue has been identified.
They’ve built a strong team around that approach. If something needs sorting, they’re people I trust to get involved and see it through.
Tom Wilmot
Managing Director
Regeneration developer
On complex regeneration projects, execution matters just as much as strategy. J3 Advisory understands how insurance fits within the wider delivery programme and consistently provides practical, commercially focused advice that helps maintain momentum. They become part of the wider professiona team, working collaboratively with consultants, contractors and funders to help keep projects moving. They’re knowledgeable, responsive and easy to work with.
Oliver Cummings
Managing Director
Real estate investor and lender
Johnny and the J3 Advisory team have been great to work with from start to finish in obtaining the right level of LDI coverage for multiple PBSA developments. Having worked with Johnny for the past 5 years, his specialist market knowledge has been invaluable in unlocking the right insurance package for our needs
Mark Wordsworth
Director
Property receivers and advisers
Knowledgeable, enthusiastic and helpful. Johnny has assisted with various warranty issues in recovery situations .
Eamon Roberts
Building Consultancy
We’ve worked with J3 as insurance advisor on a number of complex, often distressed lending projects, as well as more straight-forward ‘from-the-start’ schemes and they’ve consistently delivered. They have close relationships with warranty insurance providers and senior decision-makers, which means things can often move faster than if we went direct.
Their knowledge of complex lending situations, including developer administrations and defaults, is excellent, and they’re always quick to respond, whether that’s a call or hopping on Teams. Their back-end support with auditing and approval teams has also been a real time-saver. We would happily recommend them.
David Chilton
CEO
Property developer and contractor
Jack and the team take the time to fully understand what’s needed, and then provide clear, practical advice. Their expertise and ability to seamlessly coordinate multiple requirements is always appreciated.
Emma Brown
Financial Director
Property developer and contractor
We work extensively with local authorities and registered providers, so performance bonds and other contractual requirements are a regular part of our projects. J3 have supported us on a number of these and understand that it isn’t simply about finding a price – the wording, capacity and requirements of the employer all need to work.
They are good at getting underneath what is actually required, dealing with the surety market and finding a practical route through, particularly where a requirement is more complicated. They’re responsive, commercial and stay involved until the bond is actually in place.”
