How long does new build conveyancing take?

The duration of the new build conveyancing process typically takes around 8-12 weeks from start to finish. However, this can vary considerably based on several factors: Shorter timelines: If the property is already built and ready to complete If you are a cash buyer with no mortgage If there is no onward chain of transactions Longer timelines: If the new build is still under construction If you hit delays or revisions from the developer If you are part of a chain of sales and purchases If any issues arise during conveyancing searches Developers often stipulate a tight timeframe of around 28 days from reservation to exchange of contracts . But this is often an ambitious goal.

What happens if my new build is delayed?

Depending on how long your new build is delayed by your conveyancer may need to take steps such as requesting a mortgage offer extension from your lender, renegotiating the contract exchange date with the developer, and potentially re-doing any expired legal work. Significant delays may also require rescheduling your removal plans and temporary accommodations.

Is new-build conveyancing more difficult?

Yes, new-build conveyancing is generally more complex compared to purchasing an existing property. This is because conveyancers must conduct additional checks on planning permissions, building regulations, and the full development title deeds. They’ll also need to review special construction warranties and incentives offered by developers. Dealing with developers rather than individual sellers can mean less flexibility.

New build conveyancing explained

Purchasing a brand new property is an exciting step. However, the conveyancing process and timeline for new builds work differently from existing properties – and understanding these differences upfront will help ensure a smooth journey to your new front door.

Unlike traditional property purchases where you’re buying from previous owners, new build conveyancing involves working directly with developers.

This brings unique opportunities like warranties, potential incentives, and the excitement of being a property’s first owner. It also means navigating different timelines, documentation requirements, and legal processes.

Whether you're exploring show homes or ready to reserve your plot, this guide breaks down new build conveyancing and the timeline for you, covering everything from legal fees to completion deadlines.
