What is a Snagging List for New Build 2026

13 April 2026 • 4 min read

A snagging list is a formal record of defects or unfinished work, used to notify the developer so problems can be fixed. Because construction moves quickly, buyers must inspect early to catch any issues before they escalate.

Key Takeaways:

A snagging list is a detailed report of defects or unfinished work identified in a new build property before or shortly after completion.
In England and Wales, developers are responsible for fixing snags under the terms of the purchase contract and new build warranty schemes such as NHBC.
A snagging inspection can be carried out before completion (pre-completion inspection) or after moving in, depending on the developer’s process.
Common snagging issues include cosmetic defects, poor finishes, plumbing faults, and incomplete installations.
Buyers can carry out their own inspection or instruct a professional snagging surveyor for a more detailed report.
Snagging lists help ensure issues are formally recorded and resolved, reducing the risk of disputes after completion.
Developers are typically given a reasonable timeframe to fix defects, although timelines can vary depending on the issue.

In England and Wales, most new builds are covered by warranty providers such as NHBC and Buildmark and must comply with the Consumer Code for Home Builders. Since 2022, the New Homes Quality Code (NHQC) and the New Homes Ombudsman Service have introduced additional protections, providing buyers with a structured route to escalate unresolved disputes. Developers of higher-risk buildings also have additional obligations under the Building Safety Act 2022 to ensure safety and quality standards are met.

What Is a Snagging List for a New Build Property?

A snagging list documents defects, incomplete work, or quality issues in a new home. Snags can range from minor cosmetic problems, such as paint imperfections, to more serious issues, including plumbing, electrical, or structural concerns. It serves as a formal notice to the developer, so issues are addressed either pre-completion (if allowed) or shortly after moving in. It also complements the wider legal and quality protections provided under the Consumer Code, NHBC Buildmark, and NHQC.

How a Snagging List Protects Buyers Before Completion

A snagging list protects buyers by formally recording defects, so the developer cannot claim they were unaware of an issue. Early inspection and documentation give buyers leverage to request remediation before completion, helping to avoid costly repairs later. Conveyancers can advise on whether to delay completion if serious issues are unresolved, and they can help protect the deposit until defects are addressed.

What Should Be Included in a New Build Snagging List?

A thorough snagging list should cover:

Internal finishes: walls, ceilings, floors, doors, windows, kitchens, bathrooms, and appliances.
External elements: brickwork, roofing, drainage, driveways, landscaping.
Systems: plumbing, heating, electrics, ventilation.
Professional inspection details: photographs, measurements, and detailed descriptions for clarity and record-keeping.

Professional snagging surveys typically cost £300–£600 for standard new builds. Look for RICS-accredited surveyors or firms with specialist new build experience.

When Should You Carry Out a Snagging Inspection in the UK?

Some developers allow pre-completion inspections, giving buyers a chance to identify defects before legal completion. Most inspections occur shortly after moving in, ideally within 7–14 days, when defects are easier to spot and record. Prompt reporting ensures eligibility for repair under the two-year defect liability period, while the ten-year structural warranty covers major structural faults, such as foundation issues, roof collapses, or load-bearing wall failures.

Who Is Responsible for Fixing Snags in a New Build Home?

The developer is responsible for correcting defects under the purchase contract and warranty agreements. Minor cosmetic issues are usually scheduled within a few weeks, while major or safety-related issues are prioritised. Warranties and the Consumer Code provide guidance on expected response times, which buyers can reference if delays occur.

If a developer fails to act, buyers can first escalate the issue to the warranty provider, such as NHBC Buildmark, and, if necessary, to the New Homes Ombudsman. Keeping detailed records, photographs, emails, inspection reports, and correspondence, strengthens any claims under warranties or legal contracts.

How Snagging Intersects With Conveyancing

Snagging affects the legal side of buying a new home. Unresolved defects may influence whether you proceed with completion or request remediation first. Conveyancers can advise on notices to complete and help protect your deposit if delays occur. At Muve, we help buyers navigate snagging alongside conveyancing to ensure deadlines are met, contracts are reviewed, and deposits are safeguarded.

FAQs: Snagging Lists for New Builds (UK)

How legally important is a snagging list?

A snagging list itself is not a legally binding document, but it is extremely important in practice. It serves as a formal record of defects, unfinished work, or issues with a newly purchased property. By documenting these problems, the buyer officially notifies the developer, which can be critical if disputes arise later. The list doesn’t replace legal contracts or warranties, but it can support claims under the builder’s warranty, the terms of the purchase agreement, or even under consumer protection laws.

Can I do my own snagging inspection?

Yes, buyers can carry out their own snagging inspection, especially for obvious defects such as scratches, paint issues, plumbing leaks, or misaligned fittings. However, professional snagging surveyors often spot hidden or technical issues that a typical homeowner might miss, such as poor insulation, electrical faults, or structural concerns. Hiring a professional can provide a more comprehensive report, often with photographic evidence, which can be useful if disputes arise with the developer. Even if you do the inspection yourself, it’s recommended to document everything carefully and include photos, measurements, and dates.

How long does a developer have to fix snags?

There is no universally fixed timeframe for developers to resolve snags, as it often depends on the issue’s complexity and the terms of the contract. Generally, developers are expected to resolve defects within a “reasonable period.” Urgent safety-related issues, such as electrical hazards or leaks, are usually prioritised and addressed more quickly. Minor cosmetic issues, such as small paint defects or finishing touches, may take longer to schedule. It’s good practice to follow up regularly and request written confirmation of completion timelines. If delays become excessive, the snagging list and associated correspondence can support any claims you make under your warranty or contract.
