Buying a new build property in Portsmouth should mean purchasing a pristine, defect-free home with modern standards and warranty protection. However, as property surveyors who conduct numerous snagging inspections across Portsmouth's new developments—from Port Solent to Gunwharf Quays—we regularly identify 50-150+ defects per property that developers should have rectified before handover. Professional snagging surveys protect buyers by identifying construction defects, incomplete works, and quality issues before legal completion, ensuring developers remedy problems while they're still motivated and you haven't yet exchanged contracts. This comprehensive guide explains everything new build buyers need to know about snagging surveys, from common defects to understanding your rights and warranties.
Many first-time buyers assume new builds don't need surveys because they come with NHBC or similar warranties. This is a costly misunderstanding. Warranties are not substitutes for professional inspection, and identifying defects before completion gives you far stronger negotiating power than discovering them after you've moved in.
What is a Snagging Survey?
A snagging survey (also called a new build inspection or pre-completion survey) is a detailed professional inspection of a new or newly converted property, typically conducted in the weeks before legal completion. The inspector creates a comprehensive snagging list documenting all defects, incomplete works, and quality issues for the developer to remedy.
What Snagging Surveys Cover:
Snagging Inspection Scope
- Construction defects – poor workmanship, incorrect installation, building regulation non-compliance
- Finishing defects – painting, tiling, flooring, joinery issues
- Incomplete works – items not finished, missing elements
- Cosmetic defects – scratches, marks, chips, damage to fixtures
- Services testing – checking switches, sockets, plumbing, heating functionality
- External areas – driveways, boundaries, drainage, external finishes
- Safety concerns – handrails, guards, fire safety measures
- Specification compliance – verifying property matches agreed specification
Snagging vs Standard Building Survey:
Snagging surveys focus on identifying defects in brand-new properties before completion, while standard building surveys assess condition and structural integrity of existing properties. New builds require snagging surveys because:
- Defects must be identified before legal completion for maximum leverage
- Focus is on workmanship quality, finishing, and specification compliance
- Detailed checklist approach documents every issue for developer rectification
- Photographic evidence essential for disputed items
- Inspection conducted while developer still motivated to remedy issues
Why New Build Properties Need Professional Snagging Surveys
Several compelling reasons justify professional snagging survey costs (typically £300-£600):
1. Developers' Quality Control is Insufficient
Developers conduct their own inspections, but their priority is completing sales and moving to the next project. Our experience across Portsmouth developments shows average new builds have 50-150 identifiable defects, with some exceeding 200 issues. Developers' internal inspections typically identify only 20-30% of defects professional surveyors find.
2. Warranties Don't Cover Everything
NHBC (National House Building Council) and similar warranties provide important protection but have significant limitations:
NHBC Warranty Coverage:
- Years 1-2: Developer responsible for defects (Buildmark cover)
- Years 3-10: NHBC covers major structural defects only
- Not covered: Cosmetic defects, minor finishing issues, shrinkage cracks, many quality concerns
The Problem:
After completion, developers are less motivated to remedy defects. They may dispute whether items are defects or argue about responsibility. You'll face delays, inconvenience, and potential legal costs enforcing warranty claims. Identifying defects BEFORE completion means developers must remedy items or you don't complete—giving you maximum leverage.
3. Post-Completion Rectification is Disruptive
Discovering defects after moving in means:
- Contractors accessing your home repeatedly
- Furniture and belongings must be moved
- Disruption to your settled life
- Potential damage during remedial works
- Stress and inconvenience
- Delays in developer response
Professional snagging before completion avoids these problems, ensuring your home is truly finished before you take possession.
4. It's Your Only Opportunity for Strong Negotiation
Before exchange of contracts, developers are motivated to complete the sale. A professional snagging list provides documented evidence of defects, giving you leverage to:
- Insist on remedial works before completion
- Negotiate price reduction for items developer won't remedy
- Delay completion until critical defects are resolved
- Walk away if defects are too extensive (rare but possible)
After completion, your negotiating position is much weaker. Developers know you've committed to the purchase and legal recourse is expensive and time-consuming.

The Professional Snagging Survey Process
1. Timing: When to Book Your Snagging Survey
Optimal Timing
Ideal timing: 2-3 weeks before your scheduled completion date. This allows:
- Developer time to remedy defects before completion
- You to review the snagging list and agree priorities
- Follow-up inspection if needed before completion
- Renegotiation if developer can't complete works in time
Minimum timing: 1 week before completion if developer rushes you, but this provides limited time for rectification.
Too early: More than 4 weeks before completion may mean additional defects occur during final construction phases, requiring second inspection.
2. The Inspection Day
Professional snagging surveys typically take 3-5 hours depending on property size. The inspector will:
Systematic Room-by-Room Inspection:
- External areas first – gardens, driveways, boundaries, external finishes
- Internal spaces systematically – each room inspected thoroughly floor to ceiling
- Test functionality – switches, sockets, taps, heating, doors, windows
- Photograph all defects – creating visual record for developer
- Note location precisely – room, wall, specific location of each defect
- Check against specification – verify property matches agreed documents
- Test safety features – smoke alarms, CO detectors, guards, railings
- Review documentation – check provided manuals, warranties, certificates
3. The Snagging Report
You'll receive a comprehensive report (typically 20-60 pages) including:
- Executive summary – overview of findings and priorities
- Detailed defect list – categorized by room and severity
- Photographic evidence – images of every significant defect
- Location descriptions – precise identification of each issue
- Priority ratings – urgent, significant, minor classification
- Specification non-compliance – items not matching agreed specification
- Safety concerns – any building regulation or safety issues
- Recommendations – suggested actions and priorities
What to Do With Your Snagging Report
Post-Survey Action Plan
Step 1: Review the Report Thoroughly
Read your snagging report completely, understanding each defect and its significance. Discuss any unclear items with your surveyor—most include follow-up consultation.
Step 2: Submit to Developer Immediately
Send the complete report to your developer's customer care or site manager. Request written acknowledgment of receipt and proposed rectification timescales.
Step 3: Prioritize Critical Items
Identify defects that MUST be remedied before completion:
- Safety issues (faulty electrics, inadequate guards)
- Major defects affecting habitability (heating not functioning, water leaks)
- Structural concerns (cracks, settlement, building regulation non-compliance)
- Specification non-compliance (wrong materials, missing items)
Step 4: Negotiate Remediation Timeline
Work with developer to establish:
- Which items they'll remedy before completion
- Which items will be completed post-completion (if you agree)
- Timescales for all remedial works
- Written commitment to complete outstanding works
Step 5: Consider Your Options
Based on developer response, you have several options:
- Proceed with completion – if critical items will be remedied beforehand or you're satisfied with developer commitments
- Delay completion – insist on defect remediation before completing purchase
- Negotiate retention – solicitor holds back funds until specific works complete
- Request price reduction – for items developer won't remedy (rare but possible)
- Walk away – if defects are extensive and developer uncooperative (very rare)
Step 6: Arrange Re-Inspection if Needed
If developer completes significant remedial works before completion, arrange follow-up inspection (often included in original survey cost or £150-£250 additional) to verify quality of repairs.
Step 7: Document Everything
Keep copies of:
- Original snagging report
- All correspondence with developer
- Developer's commitments and timescales
- Photos of completed remedial works
- Signed-off items lists
Snagging Survey Costs
Professional snagging surveys in Portsmouth typically cost:
| Property Type | Typical Cost | Inspection Duration |
|---|---|---|
| 1-Bed Apartment | £250-£350 | 2-3 hours |
| 2-Bed Apartment/House | £300-£450 | 3-4 hours |
| 3-Bed House | £400-£550 | 4-5 hours |
| 4-Bed House | £500-£700 | 5-6 hours |
| 5+ Bed House | £650-£900+ | 6-8 hours |
What's Included: Comprehensive inspection, detailed report with photographs, defect list with priorities, follow-up phone consultation.
Additional Costs: Re-inspection after remedial works: £150-£300 depending on extent of works completed.
Is Snagging Survey Cost Worth It?
Absolutely yes. Consider:
- Average snagging survey identifies £3,000-£8,000 worth of defects
- Remediation post-completion is disruptive and stressful
- Developers are far less motivated after completion
- Legal costs enforcing warranty claims can exceed £2,000-£5,000
- Your £400-£600 survey investment provides leverage ensuring £3,000-£8,000 of work completed properly
ROI (Return on Investment) on snagging surveys typically exceeds 500-1,000%. It's one of the best investments new build buyers can make.
Understanding Your New Build Warranties
Most Portsmouth new builds come with NHBC Buildmark or similar warranty. Understanding coverage is essential:
NHBC Buildmark 10-Year Warranty:
Period 1: Pre-Completion (Developer's Responsibility)
Developer must complete property to NHBC standards before handover. Snagging surveys identify where they've failed to meet these standards.
Period 2: Years 1-2 (Developer Defects Coverage)
Coverage: Developer responsible for defects caused by non-compliance with NHBC standards, including:
- Defective workmanship and materials
- Damage to property, fixtures, fittings
- Incomplete works
Process: Report defects to developer who must remedy within reasonable timeframe. If developer fails, NHBC steps in.
Exclusions: Normal shrinkage, fair wear and tear, damage you cause.
Period 3: Years 3-10 (Major Structural Defects Only)
Coverage: NHBC covers only major structural defects affecting:
- Structural stability
- Weather-tightness
- Foundations, load-bearing walls, roofs
NOT covered: Cosmetic defects, minor issues, most finishing problems, general wear and tear.
Excess: Typically £1,000-£1,500 excess applies to claims.
Other Warranty Providers:
Similar warranties include Premier Guarantee, LABC Warranty, Checkmate, and Self-Build Zone. Coverage is broadly similar but check specific policy details.
Frequently Asked Questions
Do I really need a snagging survey if my new build has an NHBC warranty?
Yes, absolutely. NHBC warranties are valuable but they're not substitutes for professional inspection. Warranties cover you AFTER purchase, but snagging surveys give you leverage BEFORE completion when developers are most motivated. After completion, enforcing warranty claims requires time, persistence, and often legal assistance. Snagging surveys identify defects while you still have maximum negotiating power—before you've exchanged contracts.
Can't I just do my own snagging inspection?
You can, but professional surveyors have construction knowledge, experience, and trained eyes that identify defects most buyers miss. Professional reports typically find 3-5 times more issues than buyer DIY inspections. Additionally, developers take professional reports more seriously than buyer lists. If you're spending £200,000-£500,000 on a property, investing £400-£600 for professional inspection provides excellent value and peace of mind.
What happens if the developer refuses to fix items on my snagging list?
This is rare for legitimate defects identified in professional reports. If it occurs: 1) Escalate to developer's head office customer care; 2) Reference NHBC standards showing developer non-compliance; 3) Consider delaying completion until critical items remedied; 4) Negotiate price reduction for items developer won't fix; 5) As last resort, walk away before exchanging contracts. After completion, report unresolved defects to NHBC who may enforce compliance if defects breach standards.
How long does it take developers to fix snagging issues?
It varies significantly. Simple cosmetic defects might be completed within days; complex issues can take weeks or months. Typical timeline: Minor items (repainting, adjusting doors): 1-2 weeks. Moderate items (tiling repairs, kitchen adjustments): 2-4 weeks. Major items (heating system faults, structural concerns): 4-12+ weeks. Developers prioritize based on severity and your completion deadline. Critical defects should be remedied before completion; minor cosmetic issues might be completed post-completion with your agreement.
Should I delay completion if there are snagging issues?
It depends on severity. Delay completion if: critical safety issues exist (faulty electrics, inadequate guards); major systems don't function (no heating, water leaks); specification isn't met (wrong materials, missing items); structural concerns identified. Don't delay for: minor cosmetic defects; small finishing issues; items developer commits to remedy post-completion. Get written developer commitments for post-completion works with specific timescales. Many buyers accept minor outstanding items if developer provides credible commitments.
Can I claim compensation if my new build has defects?
Compensation for defects themselves is rare—developers are required to remedy defects, not pay compensation. However, compensation may be possible for: consequential losses (damaged possessions from water leaks); costs you incur due to developer delays; alternative accommodation if property uninhabitable during major repairs. For significant issues, consult a solicitor specializing in construction disputes. Prevention through professional snagging before completion avoids most compensation scenarios.
What's the difference between snagging and defects during the warranty period?
Snagging refers to defects identified before or immediately after completion—items that should have been completed properly initially. Warranty defects are problems that develop later despite initially appearing acceptable—for example, settlement cracks appearing after 6 months, or heating system failures after winter. Snagging surveys catch finish and workmanship issues; warranty claims address problems that emerge during occupation. Both are important, but snagging identification before completion provides strongest buyer leverage.
Conclusion
Professional snagging surveys are essential protection for new build buyers in Portsmouth. While developers provide warranties and conduct their own inspections, independent professional surveys identify significantly more defects and provide buyers with crucial leverage before legal completion.
