London’s property market sees thousands of new builds handed over every year, from high-rise flats in Greenwich Peninsula to apartment developments in Barnet. Many buyers assume a brand new home will be flawless, especially with a ten-year NHBC warranty in place. The reality is different.
The Home Builders Federation (HBF) has consistently found that the majority of new home buyers report snags to their builder. In 2021, 95% reported defects and around 1 in 4 flagged 16 or more. Now let’s find out if you really need a home survey on a new build in London, as quickly and succinctly as possible.
Hidden Defects Behind Fresh Paint
Developers face intense pressure to meet completion targets, and the finishing suffers. Plaster cracks, poorly fitted doors and badly connected plumbing turn up in new properties all the time. Most new builds come with an NHBC Buildmark warranty, but the cover isn’t as broad as buyers expect:
- For the first two years the builder is on the hook for workmanship defects against NHBC standards.
- From years 3 to 10 the cover narrows sharply to structural and weatherproofing issues only.
- There’s also pre-completion deposit protection if the builder goes bust before handover. Still, the parts that matter most to buyers are the two points just above.
Loose skirting, poor tiling and scratched glazing sit outside the insurance side entirely, so if you don’t catch them before completion you’ll be chasing the developer directly. Booking an independent home survey in London before you complete will flag these defects in writing, so you’ll hand the developer a clear fix-list while you still have leverage.
The Truth About New Build Warranties
The NHBC Buildmark won’t protect you from bad finishing. In years 3 to 10, it only covers structural damage to things like foundations, load-bearing walls and roofs. Cosmetic problems, minor plumbing issues and poor finishing are your problem once that two-year builder warranty ends.
And even during those first two years, getting a developer back on site to fix snags after you’ve moved in and they’ve moved on to the next phase is a fight most buyers lose.
The Verdict: Yes, You Need One
Spending a tiny bit on an expert inspection upfront will save you months of arguments with developers. Don’t risk your deposit on the assumption that new always means perfect.
