J3 Advisory Structural Warranty

New Build Warranty Insurance

New Build Warranty Provider

The increased number of providers in the new build warranty market has resulted in property professionals being inundated with various proposals from providers offering their services.

As a result, the need for unconflicted, truly independent advice has become essential. With experience in advising and arranging policies across the residential spectrum, J3 guides their clients through the process with concise, accurate and timely advice on all options available to them.

Since our launch in 2021, we have placed building warranties on a number of projects – the more notable cases include a £17m residential scheme in East London & structural warranties on £26m worth of developments across Skillcrown & Epicho Homes.

At J3, we don’t always go to every corner of the market- our experience, relationship, and networks ensure we have access to the right ones, ultimately saving our clients time and money. When your next project does come into focus, we would be happy to talk through the scheme and offer our pragmatic and unconflicted advice on the right building warranty insurance policy for you.

For developments containing a combination of homes for sale, private rental, social housing and commercial, it’s vital to seek trusted and impartial warranty advice. At J3 Advisory, we cover this under our Mixed Use Scheme.

Projects with a contract value above £25m, professionals will benefit from our Major Projects Scheme.

The benefits of our New Build Warranty:

  • First party insurance
  • Flexible defect periods for 0-2 years
  • 10-to-12 year new building warranty cover from practical completion
  • UK Finance approved, recognised and accepted by mortgage lenders
