A snag list format that works for a contractor groups defects by trade and location with enough detail to price and schedule the fix, while a homeowner format groups the same defects by room so an occupant can track what’s outstanding.
Why format matters more than most people think
A snag list is only as useful as the person who has to act on it. A homeowner reading a list wants to know what is wrong in each room and whether it has been fixed. A contractor reading the same list wants to know what trade it belongs to, where exactly it is, and what needs to happen to close it out. Those are different jobs, and a list built for one reader often frustrates the other.
This matters at handover stage on a new build, where the list might pass between a buyer, a site manager, and several subcontractors before anything gets touched. If the format does not match how the work gets allocated, items get missed, duplicated, or sit unassigned.
The homeowner format: grouped by room
Most snagging lists handed to a buyer are organised room by room, because that is how a person walks a house and that is how they will check it off later. A typical entry reads something like: Kitchen, cabinet door misaligned, photo attached.
- Easy to cross-reference against a floor plan
- Simple for a non-trade person to verify a fix has happened
- Does not tell you who is doing the work or in what order
The trade format: grouped by trade and ready to action
A contractor or site manager working through a list needs it sorted by trade, not just by room, because that is how work gets scheduled and subcontracted. The same cabinet door issue becomes: Joinery, kitchen, cabinet door misaligned, hinge adjustment required.
- Grouped by trade so a joiner, electrician or decorator only sees their own items
- Still tagged by room or location so nobody has to search for it on site
- Includes enough description to price and schedule, not just note that something looks wrong
- Photo evidence with the defect marked on it, so there is no argument about what was actually flagged
What a trade format needs to include to be useful
A list that just says ’paint chip, bedroom 2’ is not much help to the decorator who has to return and fix it. A format built for trades tends to carry a few things as standard.
- 1Trade category, so items route to the right subcontractor without someone re-sorting the list manually
- 2Location detail precise enough to find the defect without a second visit
- 3A photo with the defect circled or marked, not just a general room shot
- 4A short spoken or written note describing what is wrong, not just a label
- 5Status, so closed items do not keep reappearing on every reissue of the list
This is the gap most paper or spreadsheet snag lists fall into. Photos end up in one folder, notes in another, and matching them back up at the point of handover takes longer than the original inspection. An app built for site visits, such as SayScope, keeps the photo, the marked-up circle, and the spoken note together against each item, then sorts the same list by room or by trade depending on who is reading it.
Formal pre-completion inspections and format
Under the New Homes Quality Code Version 2, March 2026, a buyer has the right to a pre-completion inspection and may appoint a professional from a recognised body such as CABE, CIOB, ICWCI, RICS or RPSA with professional indemnity insurance, or carry it out themselves using the NHQB checklist. Where issues breach warranty technical standards, the developer addresses them, ideally before legal completion or within 30 days.
A professional snagging survey typically costs £300 to £600 depending on property size, and the report that comes back from one is usually already built in a trade-ready format, because the surveyor knows it will be passed to site staff for action, not just kept by the buyer as a record.
