Buying a new build home often feels like a fresh start, a chance to move into a property that’s modern, clean, and ready to live in. But even brand-new homes can have hidden issues. That’s where a pre completion survey comes in. This inspection helps spot problems before you finalize the purchase, giving you peace of mind and a stronger position to request repairs or adjustments.
This post explains why a pre completion survey matters, what it involves, and how a snagging inspection by a professional snagging company can protect your investment.
What Is a Pre Completion Survey?
A pre completion survey is a detailed inspection of a new build property before you complete the purchase. It focuses on identifying defects, unfinished work, or poor-quality finishes that the builder needs to fix. This survey is different from a basic viewing or a valuation; it’s a thorough check of the property’s condition.
The survey usually happens a few weeks before the completion date. It gives you time to raise concerns with the developer and ensure they address any issues before you move in.
Why You Should Get a Pre Completion Survey on a New Build
Many buyers assume new builds are flawless, but this is not always true. Builders work to tight schedules and budgets, which can lead to mistakes or rushed finishes. A snagging inspection helps you:
Identify defects early: From cracked tiles to faulty wiring, a snagging company will spot problems that might be missed by an untrained eye.
Avoid costly repairs later: Fixing issues after you move in can be expensive and stressful. A pre completion survey helps you avoid this by making sure the builder fixes problems first.
Strengthen your negotiation power: If the survey finds defects, you can ask the builder to fix them before completion or negotiate a price reduction.
Ensure compliance with building standards: The survey checks that the property meets safety and quality standards, protecting your long-term investment.
What Does a Snagging Inspection Cover?
A snagging inspection is a key part of the pre completion survey. A newbuild snagging inspector will examine every part of the property, including:
Walls, ceilings, and floors for cracks, stains, or uneven finishes
Doors and windows for proper fitting and smooth operation
Plumbing and heating systems for leaks or faults
Electrical installations for safety and functionality
Kitchen and bathroom fittings for damage or poor installation
External areas like driveways, gardens, and fences
The inspector will prepare a detailed report listing all defects and issues, often with photos. This report becomes your checklist for the builder to fix before you complete the purchase.
How to Choose the Right Snagging Company
Not all snagging companies offer the same quality of service. When choosing a snagging company, consider:
Experience with new builds: Look for companies that specialize in new build properties and understand common issues.
Qualifications and certifications: Check if the inspectors have relevant qualifications or belong to professional bodies.
Clear and detailed reports: The report should be easy to understand and include clear photos.
Good reviews and recommendations: Ask for references or read online reviews to find a trusted company.
Transparent pricing: Make sure you understand the cost upfront and what the service includes.
Hiring a reputable snagging company ensures you get a thorough inspection and a report that helps you protect your new home.
When Should You Arrange a Pre Completion Survey?
Timing is important. The survey should happen close enough to completion that the property is nearly finished but early enough to allow time for repairs. Typically, this means booking the survey about 2 to 4 weeks before your completion date.
If you book too early, some defects might not be visible yet. If you book too late, the builder may not have enough time to fix issues before you move in.
What Happens After the Survey?
Once you receive the snagging inspection report, review it carefully. Share it with your solicitor or conveyancer, who can then contact the builder to request repairs or adjustments.
Most builders will agree to fix legitimate defects before completion, as it protects their reputation and avoids disputes. Keep a record of all communications and agreements.
If the builder refuses to fix serious issues, you may have grounds to delay completion or negotiate compensation. This is why having a professional report is so valuable.
Real-Life Example
A couple bought a new build home and skipped the pre completion survey to save money. After moving in, they found several problems: leaking taps, poorly fitted kitchen units, and cracks in the plasterwork. Repair costs quickly added up to thousands of pounds.
Had they hired a newbuild snagging inspector, these issues would have been spotted before completion. The builder would have been responsible for fixing them, saving the couple time, money, and stress.
Final Thoughts
A pre completion survey is a smart step when buying a new build. It uncovers hidden defects, helps you avoid unexpected repair costs, and gives you confidence in your new home. Working with a professional snagging company ensures a thorough snagging inspection and a clear report to support your case with the builder.
If you want to protect your investment and move into your new build with peace of mind, arranging a pre completion survey is a wise choice. Don’t wait until after you’ve moved in to discover problems that could have been fixed earlier.
