The hidden costs of defects
Buying a new-build home should feel like stepping into your dream property. Fresh paint, modern fittings, and the peace of mind that comes with a brand-new space. But for many UK homeowners, the reality is far less perfect.
Research from the Home Builders Federation shows that over 93% of new-build buyers report defects or snags after moving in. Some of these are minor - a loose hinge, a scuffed wall - but others can become costly structural or water-damage problems if left unchecked.
That’s where snagging inspections make a difference. By identifying issues before you move in (and while the builder is still responsible for fixing them), snagging can literally save you thousands of pounds in repair bills.

The Hidden Costs of Defects
At first glance, a £500 snagging inspection might look like an unnecessary extra. After all, shouldn’t a new home be flawless? The reality is quite different.
Here are common defects and their potential hidden costs if missed:
Leaking shower tray → Small leak, unnoticed for months, leads to £4,500 water damage repair.
Poor roof flashing → One winter storm causes ingress, £7,000 roof replacement required.
Missing insulation → Cold draughts, rising bills = £1,200 extra heating costs over 5 years.
Electrical socket faults → Safety risk and rewiring costs £2,000+ if not caught early.
When you add up just one or two of these, the cost of missing defects dwarfs the price of an inspection.
Why Snagging Delivers ROI
Snagging is not just about identifying issues - it’s about protecting your position as a homeowner.
Benefits include:
Financial ROI → Average snagging inspection uncovers 20–50 defects with potential repairs worth thousands.
Negotiation leverage → Builders are obliged to fix defects before handover if flagged.
Peace of mind → Move in knowing issues are documented and addressed.
Professional eye → Inspectors use tools and experience to spot defects homeowners rarely notice.
Think of snagging as an insurance policy you control: a one-time investment that prevents major future costs.
The Bigger Picture
Snagging is not about criticising builders - it’s about ensuring quality, safety, and compliance. Even the best developers can miss details when working at scale. With nearly every new build in the UK containing snags, ignoring the issue simply isn’t worth the risk.
For self-builders and SME developers, snagging inspections are equally important. They:
Ensure lenders and insurers see quality evidence.
Reduce disputes between contractors and homeowners.
Build trust and confidence in your finished product.
Conclusion: A Small Step, a Huge Saving
Skipping a snagging inspection might save you a few hundred pounds upfront. But it could cost you tens of thousands later in repairs, disputes, or reduced property value.
With defects found in over 9 out of 10 new-build homes, the smarter choice is clear: get your property inspected before you sign off.
