Snagging List: The Ultimate UK Guide (2026)

A snagging list is the running record of defects, unfinished items and quality issues found on a UK construction project — most commonly at handover on a new build. It's what a builder gives a client (or an independent snagging inspector prepares on behalf of a client) to make sure everything the contract promised has actually been delivered. This guide is the complete UK explainer: what a snagging list is, what belongs on one, what a good template looks like, how to manage the list on a live site, and how to move the whole thing off paper without the wheels coming off.

If you're a homeowner about to take handover on a new build — or a builder about to hand one over — this is the piece to read before you sign. And if you're already knee-deep in a paper snag list that nobody can find, skip to the BRCKS snagging app for the digital version of the same document.

What is a snagging list?

Snagging list meaning: a snagging list — also known as a snag list — is a written record of every small defect, unfinished item or quality issue on a construction project that needs putting right before the client accepts the works as complete. In UK residential construction, snagging is a distinct discipline: it's the last-mile quality control between "the build is finished" and "the client is happy".

The list itself is a document. It lives on a spreadsheet, a clipboard, an app or (in most cases) a mess of WhatsApp photos, and it captures for each snag: what it is, where it is, whose trade is responsible, what needs doing and whether it's been closed out. It sits alongside the site diary as one of the two most important documents at handover on a UK residential project.

Is a "snag list" the same as a "snagging list"?

Yes. "Snag list" and "snagging list" are used interchangeably in UK construction. Both refer to the same document. Americans would call it a "punch list" — but on a UK site nobody calls it that. "Snag list template" and "snagging list template" also mean the same thing.

What is a snagging report?

A snagging report is a formal write-up of a snagging inspection — usually prepared by an independent snagging inspector on behalf of the buyer of a new build. It's essentially a snagging list with a covering page, photos and (sometimes) recommendations for the developer. The snagging list is the working document; the snagging report is the deliverable.

Why the snagging list matters

On a UK residential job, the snagging list is where money is won or lost at handover. Do it well and the client accepts practical completion, the retention is released on schedule and the defects liability period runs down without drama. Do it badly — or not at all — and you're back on site every weekend for a year, chasing subcontractors for closeouts, and staring at a retention that never quite gets paid.

Three specific reasons it matters:

1. Practical completion depends on it. Under most UK residential contracts (JCT and its cousins), the client is entitled to withhold sign-off until the outstanding snag list is agreed. No snag list, no sign-off, no final payment.
2. The defects liability period is measured from it. The 12-month defects period only starts running from practical completion — which means from the moment the snag list is closed. Every week you delay closing snags is a week added to your liability.
3. Retention is released against it. Retention money — typically 3–5% of the contract value — is released in tranches tied to snag close-out. On a £1.5m contract that's £45,000–£75,000 sitting in the client's account until the snags disappear.

New build snagging list: what should be on it?

A good new build snagging list covers every room and every trade in a systematic order. Below is a working template of what to include — structured the way a good UK snagging inspector will walk the property.

Externals

• Brickwork — pointing, colour match, cracks, staining.
• Render — cracks, colour consistency, weep holes.
• Roof — tiles/slates aligned, ridge/hip caps sealed, valleys clear, flashing complete.
• Gutters and downpipes — brackets secure, discharge to gullies, no ponding.
• Windows and doors — operation, seals, ironmongery, drips.
• Driveways, paths, landscaping — falls, edging, jointing, planting.
• External lighting, sockets, meter boxes.

Every room, systematically

• Walls: plaster finish, paint coverage, joins, hairline cracks, corners.
• Ceilings: finish, cracks around downlights and access hatches, cornice/coving.
• Floors: level, squeaks, joinery joins, skirting alignment.
• Skirting and architrave: mitres, filler, paint finish.
• Doors: hang, close, catch, hinges, latches, seals.
• Windows: operation, seals, trickle vents, sill finish.
• Electrical: sockets tested, switches, downlights, cover plates, test certificates.
• Radiators/heating: secure, level, bleed valves, TRVs.
• Sanitaryware (bathrooms): silicone lines, tap operation, waste flow, tile finish.
• Kitchen: unit doors, drawer runners, worktop joins, appliance install, tap operation.

Services and commissioning

• Boiler commissioning certificate.
• Electrical Installation Certificate (EIC) and Part P notification.
• Gas Safe certificate.
• MVHR/ventilation commissioning.
• Fire alarm commissioning.
• Building Control completion certificate.
• NHBC / LABC / structural warranty documents.

Handover pack

• Operation and maintenance manuals.
• Product datasheets and warranties.
• Appliance manuals.
• Keys and codes.
• Emergency contacts.

If you're a homeowner walking a new build for the first time — take this list with you, room by room. If you're a builder handing over — walk it yourself two weeks before you invite the client. It's much cheaper to find the snag before the client does.

Snag list template: the fields that matter

A good snag list template — or snagging list template, same thing — has a small number of well-chosen fields and no fluff. If your template has thirty columns nobody will fill in twenty-five of them. Here's the minimum viable set:

• Snag ID — a number or reference so the snag is traceable.
• Location — plot, room, position ("plot 4, master bathroom, wall behind door").
• Description — what's wrong, in one sentence.
• Photo — always. A photo of a snag is worth ten paragraphs.
• Trade responsible — plasterer, decorator, plumber, electrician.
• Priority — critical / major / minor / cosmetic.
• Raised by / on — who spotted it, on what date.
• Target close-out date — when it needs fixing by.
• Status — open / in progress / closed / disputed.
• Proof of fix — photo of the completed fix, signed off by whom, on what date.

That's it. Ten fields. Everything else — categories, cost impact, risk ratings, escalation flags — is either derivable from those ten or unnecessary for a residential snagging list. Keep the template tight; you'll thank yourself at handover.

Snagging list example

Here's a snagging list example for a single entry, in the format above:

Snag 47. Plot 4, master bathroom, wall behind door. Hairline crack in plaster running 200mm vertically from door frame. Photo attached. Trade: plasterer. Priority: minor. Raised by James on 12 April. Target close: 26 April. Status: open.

Multiply that by 180 open snags across an eight-plot development and you can see why paper spreadsheets fall apart. Which brings us to the next section.

Managing the snagging list on site

The mechanics of running a snag list are where most UK builders come unstuck. The list itself is straightforward. What kills you is the ongoing operation: capturing new snags without missing them, routing them to the right trade, chasing close-outs, verifying fixes, closing the loop and keeping everyone on the same version of the truth.

The paper approach — clipboard, spreadsheet, WhatsApp photos, weekly email — falls over in three predictable places:

1. Snags get spotted and never logged. The site manager sees a cracked tile on Tuesday, means to add it to the list on Friday, doesn't. It resurfaces at handover as a new item and the client is unimpressed.
2. Photos disappear into WhatsApp scrolls. Someone sends a photo of a snag with no context. Two months later nobody knows which plot it was, which room, which trade or whether it was ever fixed.
3. Close-outs aren't verified. The decorator says the touch-up is done. Nobody goes to look. At handover the client points at the same mark and asks why it's still there.

The pattern behind all three is the same: the snag list lives in one place, the evidence lives somewhere else, and the trades are working from memory. To fix it you need one place where the snag, the photo, the assignment, the fix and the sign-off all live together.

From paper snagging list to digital snag list

Turning the snag list into a shared digital document is the single highest-leverage change you can make to your handover process. A digital snag list — captured through the BRCKS snagging app — solves the three failure modes above in one move:

1. Every snag is captured at the moment it's spotted, from a WhatsApp photo. The site manager snaps a cracked tile in Plot 4 master bath and drops it into the BRCKS number — BRCKS reads the location cues, creates snag #47, files the photo, assigns it to the decorator and drops it into the trade's daily list.
2. The photo lives with the snag. Not in a group chat. Not on someone's phone. On the snag record, at full resolution, with the date and time it was taken. Six months later it's still there.
3. Close-outs need photo proof. The decorator can't tick the snag as closed without sending back a proof-of-fix photo. The office sees the before-and-after side by side and decides whether to accept the close-out.

The result is a live, shared, dated, photographed snagging list that produces a clean handover pack automatically. No end-of-project rebuild of the spreadsheet. No hunt for photos. No "I know we agreed it, I just can't find where". And crucially, the site team doesn't have to change how they work — they carry on messaging photos to the same WhatsApp number they already message the office on.

If you want to see it running on a live snag list before you commit, the trial is free and takes about ten minutes to set up.

Snagging list FAQ

What is a snagging list?

A snagging list is the running record of defects, unfinished items and quality issues on a UK construction project, captured for close-out before the client accepts practical completion. It sits alongside the site diary as one of the two most important documents at handover on a UK residential job.

What should a snagging list template include?

A minimum viable snag list template has ten fields: snag ID, location, description, photo, trade responsible, priority, raised by and date, target close-out date, status and proof-of-fix. Anything beyond that is optional. Anything less than that is incomplete.

Who prepares the snagging list?

The site manager or the client's independent snagging inspector prepares the initial list; the builder adds to and closes items as trades work through them. On smaller residential jobs the builder and the client walk it together. On new builds it's increasingly common to appoint an independent snagging inspector to prepare the handover snag list — see our forthcoming snagging inspection guide for how that works.

How do I move my snag list off paper?

Use a digital snag list tool — the BRCKS snagging app is built for exactly this. Every snag captured from a WhatsApp photo, filed against the right plot and trade, closed out with photo proof, exported as a PDF handover pack. Free trial, card required at signup.

What's the difference between a snag list and a defect?

A snag is typically a minor quality issue captured before or at practical completion. A defect is anything that emerges during the defects liability period (usually 12 months after PC). The snag list closes at handover; the defects list runs for a year afterwards. Same underlying discipline, different phase of the project.
