Snagging meaning: what is snagging in a new build?
Snagging means checking your new build home for faults and documenting them in writing, so that your developer or housing provider can resolve them.
This page outlines what a snag is, what snagging involves, how a snag differs from a defect, why it matters to you as the buyer, and what a good snag list contains.
The content in this article applies to any new build home in the UK, whether you inspect before completion or after you move in. sendingsnags is independent. We're not part of, or endorsed by, the New Homes Quality Board or the New Homes Ombudsman Service.
What is a snag?
A snag is something in your new home that is damaged, broken, badly fitted or unfinished.
Most snags are small. A door that catches on its frame, a patch of thin paint above a radiator, sealant missing at the back of the kitchen worktop, a socket that does not work. They are the faults left behind when a home is built to a deadline by many different trades, and almost every new home has them. In the Home Builders Federation's national customer satisfaction survey, published in March 2026, 93% of new build buyers said they had reported a problem with their home to their builder since moving in, and around a quarter had reported sixteen or more.
Where the New Homes Quality Code applies to your home, it describes a snag in the same terms: a minor imperfection or fault that does not meet the quality or finish you were sold, usually something damaged, broken, not fitted properly or looking unfinished. The Code applies where your developer is registered with the New Homes Quality Board and you reserved on or after the date their registration was activated.
A snag is not a matter of taste. A colour you would not have chosen is not a snag unless it differs from what you were sold.
What is snagging?
Snagging is walking through your home, room by room, and writing down every fault you find.
You open every door and window, run every tap, test every light and socket, and look closely at every wall, floor and ceiling. Each fault goes on your list with where it is, what you can see and a photo. You then send the list to your developer or housing provider in writing, and keep a dated copy.
Many buyers do the first part well and the second part badly. A walkthrough that finds thirty faults and records them as "paintwork poor throughout" is not useful. Your list is what your developer works from, and it is your record of the condition of the home on the day you took it on.
What is the difference between a snag and a defect?
A snag is a fault in the finish or the fittings. A defect is a fault in the way the home was built.
The two words are often used loosely, and you do not need to decide which one applies. Report everything you can see to your developer or housing provider, and say where a fault may be a sign of a potentially larger issue. A crack you can see is something to report. Whether it is a snag, a defect, or both is for your developer or a specialist to assess.
A structural defect may be covered by your new home warranty, which has its own process. Your warranty documents should say what it covers and when you can use it.
Why does snagging matter?
The faults you report early are your developer's to resolve. The faults you never report may become yours.
Four reasons to snag your home properly:
- Money. Where the New Homes Quality Code applies, your developer is responsible for resolving snags and defects that arise in the first two years after completion. Where it does not apply, your reservation paperwork and your warranty name the period. A fault found after that period may be yours to pay for.
- Safety. A loose handrail, exposed wiring or a front door that will not lock is a hazard, and a walkthrough is how you find it before it hurts someone. Anything that poses an immediate threat is reported the day you find it, through your developer's emergency contacts, not through your list.
- Evidence. A dated list with photos records the condition of the home on the day you took it on. A crack that grows, or a leak that appears in the first winter, is far harder to dispute when you can show what was there at the start.
- A finished home. Dozens of small faults add up. The home you paid for is the one with them resolved.
Where the Code applies, it also asks you to report issues as soon as possible so that your developer can meet their responsibilities, and it gives you two years from reservation or completion, whichever is later, to make a formal complaint.
Who does the snagging?
You can, and most buyers do.
You do not need qualifications, or equipment beyond a phone, a tape measure and somewhere to record what you find. A second person can make the process faster. A professional inspector is worth considering for a large or complex home, for signs of damp or movement you cannot assess, or where your developer has disputed your list.
Our page on whether you can do your own snagging inspection covers what to bring and what you can realistically check yourself, and our page on your right to inspect your own new build covers what the Code says about inspecting before completion.
Should you pay for snagging?
Not necessarily, and most buyers do it themselves for free.
Professional snagging inspections are typically advertised at £350 to £600 for a single visit, depending on the size of the home, where it is, and what the inspection includes. Larger homes, London and the South East, a second visit and add-ons such as thermal imaging cost more. Get a written quote for your home if you are considering one.
A professional inspection is worth it where you cannot be there yourself, where the home is large or complex, or where you want an independent record for a disputed claim. It is not required.
You are entitled to inspect your own home, and once you have the keys you can walk through it as often as you like. Where the New Homes Quality Code applies and you reserved on or after 2 March 2026, your developer must also give you the opportunity to carry out a pre-completion inspection yourself, using the NHQB Pre-Completion Inspection Checklist for a house or an apartment. The NHQB notes that the checklist was designed for a suitably qualified professional, so a buyer may overlook or misinterpret some of the standards the builder must follow. Read its guidance before you start. You do not need professional equipment, qualifications, or a fee to snag your own home.
Our page on whether you can do your own snagging inspection covers what a buyer can realistically check without paying for an inspector.
When does snagging happen?
At three points: at the pre-completion inspection (PCI), in your first weeks after completion, and again as the home goes through its first year.
Before completion. Where the New Homes Quality Code applies to your home, your developer must give you the opportunity to carry out a pre-completion inspection, known as a PCI, either yourself or through a suitably qualified inspector you appoint. The inspection takes place after your developer serves the notice to complete (the estimated completion date in Northern Ireland) and before the completion date, or earlier if you and your developer agree, and it is recorded on the NHQB Pre-Completion Inspection Checklist, the standard checklist the Code requires. Anything the inspection finds that falls below the warranty technical standards is your developer's to resolve, ideally before completion and within 30 days where that is not possible. The Code applies where your developer is registered with the New Homes Quality Board and you reserved on or after the date their registration was activated. Where it does not apply, you can still ask to inspect before completion, and many developers allow it.
After completion. Your first days with the keys, before your furniture arrives where possible, are the best time to snag thoroughly. An empty home has every surface visible, and nothing can be attributed to your own use of it. If you move in on the day you complete, snag each room as you unpack it, and report what you find promptly with dated photos. Where the Code applies, snags identified after completion are dealt with through your developer's after-sales service, which must run for at least two years from the date of completion. Where it does not apply, your reservation paperwork and your warranty documents name the equivalent period.
During the first year. A new build continues to change after you move in. Plaster dries out, the structure settles, and the heating and the weather test the home for the first time. We recommend snagging again as these changes happen, and dating every list, so that a new or worsening fault can be compared against your earlier record.
Our page on your right to inspect your own new build sets out the pre-completion inspection in full, including the window for each version of the Code, and our page on when you can snag your new build covers the timing after completion, how long to allow and the best time of day.
What does a good snag list look like?
Every snag on it has a location, a plain description, a grade and a photo.
Each snag on your list carries:
- Where it is: the room and a fixed feature, such as "above the kitchen window"
- What you can see: one or two plain sentences, including the size, without guessing the cause
- How serious it is: Major, Below Standard or Cosmetic
- A photo: ideally three, one from a step back, one of the whole problem and one close-up
A list written this way is easy to act on and hard to dispute. Our pages on how to describe a snag so it's harder to dispute and what photo evidence you need for a snag cover the description and the photos in full.
How we can help
sendingsnags is an app that turns your own walkthrough of a new build home into a clear, photographed snag report you can send to your developer or housing provider. It takes you through every room with a checklist of what to look for, and each check explains what good looks like with an example drawing of the fault.
Every snag you log is photographed, described in your words with clearer wording suggested alongside, and graded, and your report comes with a sending guide for your home: who to send it to, what to expect back, and what to do if it is not resolved.
You can start your report at sendingsnags.com. We hope you find it useful.
