Snagging
Plain English. Practical detail. UK context.
Snagging is the process of identifying and recording defects or incomplete details for correction. It is a practical inspection activity, not a substitute for technical testing or required compliance checks.

What it means in practice
Use precise descriptions and locations. “Bedroom door catches at the top corner” is more actionable than “door bad”. Separate cosmetic defects, incomplete work and functional problems, and give each an owner and a status.
Keep an agreed record of corrections and reinspect them. A list which grows without version control can create disputes about what was reported, what was completed and what is genuinely new.
For homeowners
Inspect methodically and photograph issues in context. Check operation as well as appearance, but do not dismantle equipment or perform unsafe tests. Keep technical documents, commissioning checks and approvals on a separate completion checklist so that a tidy-looking finish is not mistaken for complete handover.
Practical checks
Agree a correction plan and a way to confirm completion. Escalate urgent safety concerns immediately rather than burying them among minor paint or sealant issues.
Build a list somebody can close out
Use a consistent room or element reference, a short factual description and a photograph showing both the detail and its location. State the expected correction where it is already agreed, but avoid prescribing an unsuitable technical repair. Record the date raised and when it is rechecked. Separate an incomplete item from later damage or a newly requested change, because their responsibilities may differ. Homeowners should agree reasonable access for correction and avoid covering evidence before the contractor has an opportunity to inspect. A trainee can use snagging to learn quality standards, but should not turn personal taste or a vague adjective into an unsupported defect claim.
Safety, certification and disputed work
A snagging visit is not a structural survey or a substitute for specialist testing. Escalate electrical damage, suspected gas issues or unsafe access immediately through the appropriate competent route rather than wait for a decorative list to be completed. Citizens Advice explains steps for dealing with unsatisfactory building work and the need to keep evidence of the agreement. Contractual completion and payment consequences need their own assessment; a long list does not automatically justify any amount of withholding. Keep correction records alongside commissioning and approval documents, and obtain appropriate independent advice where a disagreement cannot be resolved from the scope and evidence.
Frequently asked questions
Does snagging replace electrical or gas checks?
No. Snagging records visible defects and incomplete details within its scope. Specialist inspection, testing and certification have different purposes and need appropriately competent people.
Should I include faults I cannot safely inspect?
Record the concern and seek an appropriately competent inspection. Do not dismantle equipment, climb unsafe access or perform hazardous tests to produce a snagging photograph.
