Summary
- A professional snagger checks a new-build home for problems or unfinished work that most buyers wouldn’t notice.
- They give you a report with photos and details of where the problems are, so you can ask the builder to fix them.
- If the builder agrees, arrange the inspection before you move in.
- Before booking, make sure you understand what the inspection will cover, what it won’t cover, and what proof (like photos and a written report) you’ll receive.
- Typical cost: £300–£600. Price depends on size of the property and whether extras (thermal imaging, drone) are included.
New builds should be finished properly. But something we see a lot through our platform is buyers who only realise how many issues there are once they have moved in and started living with them. By that point, the developer's attention has moved on, and chasing fixes without a clear record becomes frustrating.
The problem is not just spotting the defects. It is having them documented clearly, with photos and locations, so the conversation with the developer stays practical rather than turning into a dispute about what counts as a problem and what does not.
That is the main reason to use a professional snagger and get a snagging survey. They bring method, experience, and evidence.
This guide explains what they actually do, whether it is worth it for your situation, when to book, and how to choose a good one.

Quick Steps to Arrange a Snagging Inspection
- Check whether your property is a new build or a newer home still within its warranty period.
- Ask your developer when access is allowed, before completion or only after.
- If pre-completion access is possible, book a pre-completion inspection (PCI).
- Check what the inspection covers: interior, exterior, drainage, driveway, roofline, and basic system checks.
- Ask what evidence you will receive: photos, locations, severity notes, and a summary you can forward to the developer.
- Compare snagging survyeors based on scope and report quality, not just price.
- After the inspection, send the snag list to the developer in writing and keep a copy.
What Does a Professional Snagger Actually Do?
A professional snagger inspects a new build property and records everything that is not right. "Snags" means defects, poor workmanship, or finishing that has not been completed properly. Snagging is most common with newly built homes, but it can also be useful for newer properties where problems have appeared within the first year or two.

The reason most people use a professional rather than doing it themselves is the method and the evidence. Rather than walking around with a loose list, they work systematically, room by room and element by element. They know what to look for and where problems tend to hide, especially the kind of issues you might miss when you are tired, rushing, or not sure what "good" looks like in a new build finish.
A snagger is not there to redesign your home or guarantee perfection. Their job is to find defects and incomplete work and present them clearly so you have something solid to raise with the developer.
What They Check
A snagging checklist usually includes:
- Interior finishes: walls, ceilings, paintwork, tiling, flooring, skirting, and sealant lines.
- Doors and windows: operation, alignment, locks, handles, drafts, and visible damage.
- Kitchens and bathrooms: fitting quality, visible leaks, silicone and grout, and finishing around units.
- Electrical and plumbing basics: visible workmanship and function checks where safe and accessible, plus obvious faults like loose fittings or leaks.
- Heating and ventilation basics: visible issues, control operation, and obvious extraction problems where accessible.
- Exterior: brickwork, pointing, render, cladding, gutters, downpipes, and visible defects.
- Outdoor areas: paths, driveways, patios, fencing, and drainage issues you can see without invasive testing.
What is included varies between inspectors. Before you book, get clarity on whether the inspection covers loft areas, roofline visibility, garages, outbuildings, and gardens, and whether any specialist testing is part of the service.
What You Should Get in the Report
A good snagging report should make it easy to take action. Look for:
- A clear list of snags with plain-English descriptions.
- Location details so issues can be found quickly (room, wall, window, or area).
- Photos where helpful, especially for defects that are hard to describe.
- A simple way to prioritise issues, for example separating functional defects from cosmetic finishing.
- A summary you can copy into an email to the developer.
If the report is vague, missing locations, or light on evidence, it becomes much harder to use and more likely to trigger back-and-forth.
Home movers we speak to often say the biggest benefit of using a professional is not just the snags themselves, but having them documented properly so the conversation with the developer feels simpler and less emotional.

Is a Snagging Survey Worth It?
Snagging survey costs in the UK are £300-£600 on average, depending on the location, size and type of home. Compared with the cost of a new build home, this is a relatively small price to pay for peace of mind.
When It's Worth It
A snagging survey is usually worth it when you want confidence that you are not missing issues that could become time-consuming to sort out later.
It is especially useful if you are buying your first new build and do not know what to look for, if your handover is being rushed and you cannot inspect calmly on the day, or if you want a proper report you can forward to the developer without having to write it yourself.
It is also worth it if you are worried about things you cannot easily judge yourself, like inconsistent finishing, poor sealing, or defects that are only obvious to someone who sees new builds regularly. The report gives you something concrete to work with, rather than trying to negotiate from memory.
When You Might Not Need One
You might decide to skip a professional snagger if you have relevant construction experience, you have enough time to inspect carefully, and you are comfortable documenting issues in a structured way. Some buyers prefer to do an initial DIY snag list first, then bring in a professional only if they spot problems they are not sure about.
If you do skip it, still take your time at handover, photograph anything that concerns you, and follow up with the developer in writing so there is a clear record.
Professional Snagger vs Surveyor
These two terms get used interchangeably, but they are not always the same thing. A professional snagger typically focuses specifically on defects and finishing in new builds. A surveyor may offer snagging as one of their services, but many surveyors also carry out broader home surveys for older or existing properties.
The simplest way to think about it:
- Snagging focuses on identifying defects, incomplete work, and workmanship issues in a new build.
- A home survey is usually broader and is commonly used when buying an older home, assessing condition and risks.
If you're unsure what you need, ask for clarity on scope and deliverables before booking.
Can You Do Your Own Snagging Survey?
Yes, but be honest with yourself about what you will catch. DIY snagging can work if you are methodical and you know what you are checking. The risk is that you miss things, you don't record them clearly enough, or you end up with a list that the developer finds easy to dismiss.
If you do it yourself, work room by room, then check exterior and outdoor areas. Photograph each issue and note the exact location. Separate functional problems from cosmetic ones. Send the list in writing and keep a copy.
If you want a report that carries more weight with the developer, a professional inspection with clear evidence is usually easier to use and harder to push back on. That is the main reason most buyers use one.
When Should Snagging be Done?
Pre-Completion Inspection
The best time for snagging is usually before you move in. A pre-completion inspection, often called a PCI, is carried out before legal completion if the developer allows access. It means defects are logged while the property is still being handed over, which makes it harder for the developer to push back or deprioritise fixes.
If you are aiming for a PCI, check with your developer when access is allowed, whether your inspector can attend, and whether utilities will be on for basic checks.
Post-Completion Snagging
Not all developers allow third-party inspections before completion. If yours does not, a post-completion snagging survey is still valuable. You can document issues early, create a clear record, and avoid the risk of forgetting details once you are busy settling in.
A post-completion inspection can also pick up problems that only become noticeable after living in the home for a while, like doors that stick, heating that does not work evenly, or drainage issues after rain.
What If the Developer Will Not Allow Access Before Completion?
If you can only get access after completion, focus on speed and evidence. Book the inspection as soon as you can after moving in. Keep your own notes and photos from day one, in case anything changes over time. Make sure the inspector provides clear locations and photos so the developer can act without guesswork.
Send the snag list to the developer in writing and keep copies of all emails and attachments. In Scotland, this would follow the conclusion of missives, which is when the sale is legally finalised.
If you are under time pressure, tell the snagger upfront. Something we see a lot is buyers who need a report they can forward quickly, with a clear summary at the top rather than pages of detail to wade through.

How to Choose a Professional Snagger
1. Independence
Start with independence. You want someone who is working for you, not someone with ties to the builder. Ask whether they have any relationship with the developer or the site. If the answer is unclear or evasive, that's a warning sign.
Independence matters because snagging involves judgement calls, like whether a finish is acceptable or whether something looks incomplete. An inspector with no ties to the developer is more likely to document issues honestly and thoroughly.
2. Qualifications and Experience
There's no specific qualification required to work as a snagging inspector. That said, look for relevant experience in new builds and clear evidence of professionalism. Useful indicators include an NVQ in The Built Environment, membership of the Chartered Institute of Building, or membership of the Chartered Association of Building Engineers.
When comparing professional snaggers through Compare My Move, all surveyors in our network are vetted. They must be registered with either the Royal Institution of Chartered Surveyors (RICS) or the Residential Property Surveyors Association (RPSA) before joining our partner network. Our partner support team monitors all partners to check they continue to meet our standards.
3. Questions to Ask Before You Book
Before you commit, ask what exactly is included and excluded, in writing. Check whether exterior areas and grounds are covered. Ask whether the report will include photos and clear location references, and how it will be structured so you can forward it to your developer easily.
Request a sample report so you can judge the clarity and usefulness for yourself. And ask whether there is any follow-up support if you spot new issues after the initial inspection.
4. Red Flags to Watch Out For
Be cautious if a snagger can't provide a written scope, or if they use vague "we check everything" language. If there's no sample report available, you have no way of knowing what you will actually receive.
Be wary of anyone who promises a fast turnaround but is unclear on what evidence they will provide, or who pushes you to book without answering basic questions. Refusal to discuss independence or potential conflicts with the developer is a serious concern.

FAQs
How much does a professional snagger cost?
Costs vary by property size, location, and what’s included in the inspection and report. A new build snagging survey costs £377 on average, with most buyers paying between £363 and £500. However, if you want a realistic range for your home, comparing quotes is usually more reliable than relying on a generic average.
What’s the difference between a snag list and a snagging survey?
A snag list can be your own notes. A snagging survey is a structured inspection with a written report, often with photos and clear locations, produced by a professional snagger.
Does a snagging inspection cover the garden and driveway?
Sometimes. Ask for the scope in writing before booking, especially for external areas, drainage visibility, garages, and boundaries.
What should I do after I receive the report?
Send the snag list to your developer in writing, attach the report, and keep a copy. If there are urgent functional or safety concerns, highlight them clearly at the top so they are triaged first.
