Scaffold tags, inspections and handover: what the HSE actually requires in 2026

Right, let's talk about tags and paperwork, because this is one of those areas where the law and the industry rules do not quite line up, and the gap costs people their jobs. Scaftag is a brand, not a regulation. The HSE wants the inspection and the record. Everything else, the plastic holder on the ladder, the colour of the tag, the little clipboard in the site hut, is industry practice.

If you are a scaffolder, you probably know this already. If you are a trade working off scaffold, read on, because the 7-day rule and the handover certificate are the two bits that catch everybody else out.

The regulation that counts

The Work at Height Regulations 2005 are the UK law. Regulation 12 sets out the inspection duties for working platforms. Scaffolding falls under this, and so does a mobile tower, a cherry picker platform, a roof edge protection system and any other platform where a person could fall 2 metres or more.

Three events trigger an inspection: completion of the scaffold or any substantial addition or dismantling, any event that is likely to have affected its stability (a vehicle impact, a severe storm, a load dropped onto it), and the passage of seven days. The 7-day rule is the one most sites tag off because it is the easiest to miss. If the scaffold was handed over Monday and the paperwork says the next inspection is due the following Monday, Tuesday is already late.

The inspection must be done by a competent person. In practice that means a Part 2 CISRS-trained scaffolder for simple structures and an Advanced CISRS for complex ones. A site manager with CITB SMSTS and a bit of scaffolding knowledge is usually not the right person to inspect anything more than a basic tower, but a lot of smaller sites rely on exactly that arrangement and get away with it until an inspector turns up.

The written report

Regulation 13 says a written report must be produced before the end of the working day in which the inspection was carried out, and a copy must be given to any person for whom the scaffold is being used within 24 hours. The report has to include who inspected, when, which scaffold, what was found and any defects.

The report lives on site for 3 months and is then kept with the main contractor's health and safety file for the duration of the project plus a reasonable period after. If an accident happens on a scaffold six months later and the reports from the last three months are missing, the HSE investigation gets a lot harder, and so does the operator's defence.

The tag system, and what it does

A scaftag or similar tag holder is bolted to the base of the ladder or the main access point. Inside sits a card with the last inspection date, the next inspection due date and the inspector's signature. Some sites use a green card for safe, red for unsafe or do not use, and yellow for restricted use.

Nobody is legally required to use the tag. But the industry grew up with it because the alternative is reading the inspection report before you climb, and the inspection report is in the site office. A tag on the ladder gives you a visible, immediate confirmation that the structure was inspected this week. If the tag is missing, blank, red or out of date, treat it the same way you would treat a scaffold with a visible defect. Do not climb. Report it to the site manager and the scaffolding contractor.

Blank tags are the quiet trap. A blank tag often means the scaffolder hung the holder when they built the scaffold and never came back to fill in the first inspection card. The scaffold is technically unused and uninspected, which means it is not fit for use. Walking past a blank tag because you assume someone forgot is the same as climbing on an unsigned structure.

The handover certificate

SG35:21 is the NASC publication that sets out the handover procedure. Not law, but it is the industry benchmark and the HSE treats it as the competent position. The handover certificate is signed by the scaffolding contractor's competent supervisor on completion. It names the scaffold, states the safe working loads, lists the intended uses, and notes any restrictions, like no sheeting without additional ties, or maximum two bays loaded simultaneously.

The site team signs the certificate to accept the scaffold. That signature transfers responsibility for the 7-day inspection cycle to the receiving party, unless the contract between scaffolder and principal contractor keeps the scaffolder on the hook for ongoing inspections (which is the more common arrangement on bigger sites).

If no handover certificate was issued, the scaffold has not formally been handed over. In theory nobody should be on it. In practice, trades go onto scaffolds without a certificate every day on small jobs. If an HSE inspector finds you on a scaffold without a handover and no first inspection on record, the person on the scaffold is as much in scope as the scaffolder, because the regulations place a duty on anyone who allows work at height to proceed.

Alterations and the quiet break of the chain

Any alteration to the scaffold since handover resets the inspection clock. A tie removed to let a window in. A guardrail eased off to pass a long length of timber. A lift adjusted to drop a work platform six inches. Each of these should be done by a competent scaffolder, inspected and re-tagged. In practice they happen every day, often by trades who are not scaffolders, and the chain of inspection breaks.

The clean rule: nobody but a competent scaffolder adjusts the scaffold. If you are a bricklayer and you need the lift at a different height, phone the scaffolder. Yes, this is a delay. The alternative is you adjust it, it fails, and the HSE investigation finds that an unqualified person reconfigured the structure.

What a trade should check before climbing

Walk the base. The scaffold should sit on sole plates on firm ground. If the base is sitting on a muddy slope with no sole boards, do not climb. Look at the ties. There should be a tie roughly every 4 metres vertically and horizontally into a solid structure, not a window frame. Look at the boards. They should be fully boarded on the lift you are going to work on, with no gaps at the ends.

Check the handrails. 950mm top rail, 470mm maximum gap to the intermediate rail. Toeboards 150mm tall on the working platform. Diagonal braces visible on alternate bays. If anything is clearly missing, do not climb. Report it to the site manager.

Look at the tag. Green and in date, you are fine. Red, missing, blank or out of date, do not use. Yellow usually means restricted use and you need to check the handover certificate for the restriction.

Weekly, daily and pre-use

The weekly inspection is the legal minimum. Any serious site runs a daily pre-use visual check, where the first trade on the scaffold each morning looks for anything obviously wrong: a plank out of place, a loose fitting, a missing clip. The daily check is not written up, but a verbal report to the site manager is standard.

After bad weather, after a vehicle impact, after any lift has been loaded with material and unloaded again, re-inspect. The regulation says any event likely to affect stability. Common sense says the same thing. The time to find out that the storm last night loosened a tie is before you climb to the fourth lift, not after.

If the HSE turn up

They will ask for the handover certificate, the latest inspection report and the inspector's qualification. If any of those three is missing, the inspector has grounds to issue a prohibition notice stopping work on the scaffold until the paperwork is sorted. On smaller sites, that often means the scaffolder has to come out same day to re-inspect and sign the paperwork, which costs the main contractor the day.

The pattern of defects the HSE sees most are: inspections overdue by one to three days (the Friday to Monday problem), handover certificates never issued on domestic work, trades altering the scaffold themselves, and tags left blank. None of these are hard to fix. The cost of fixing them in advance is 20 minutes of paperwork a week. The cost of not fixing them is a day's shutdown and a note on the company's HSE record.
