Introduction
If you’re buying a new-build home, you may have heard about snagging inspections, but should you book one before you complete, or after you move in?
The answer depends on timing, access, and how much leverage you want with the developer.
Let’s break it down.
What Is Pre-Completion Snagging?
Pre-completion snagging is carried out before legal completion, usually after the builder finishes construction but before you hand over final payment.
Advantages:
- Maximum leverage (you haven’t fully paid yet)
- Issues identified before move-in
- Cleaner documentation process
- Some developers prioritise pre-completion fixes
Disadvantages:
- Access depends on developer permission
- Sometimes rushed due to timelines
Pre-completion snagging is often considered the strongest position for buyers.
What Is Post-Completion Snagging?
Post-completion snagging is carried out after you’ve moved in, usually within the first few weeks.
Advantages:
- Full access to test systems
- Can identify issues that appear after use
- No developer approval needed for inspection
Disadvantages:
- Slightly reduced leverage
- Repairs may disrupt daily life
Most warranties cover defects for 2 years, but early reporting is essential.
Which One Is Better?
Ideally: both.
Pre-completion catches visible and compliance issues.
Post-completion can identify:
- Heating performance issues
- Water pressure problems
- Settlement cracks
- Door warping
If you must choose one, pre-completion offers stronger negotiating power.
What Developers Don’t Always Tell You
Many buyers assume new-build homes are “perfect.” They rarely are.
Developers expect snag lists — it’s standard practice. Professional snagging simply ensures nothing significant is missed.
When Should You Book?
- 2–3 weeks before completion date (for pre-completion)
- Within first 2–4 weeks after move-in (for post-completion)
Always confirm access arrangements in advance.
FAQs
Can a developer refuse a pre-completion survey?
Some may restrict access, but many allow independent inspections.
Will snagging delay completion?
Usually no, but it may affect when issues are fixed.
Is it expensive?
Compared to potential repair costs, snagging is relatively low-cost.
Conclusion
Snagging isn’t optional if you want full peace of mind.
Choosing the right timing ensures:
- Better leverage
- Faster defect resolution
- Stronger protection
For most buyers, pre-completion offers the strongest advantage.
