Needing a special safety sign? Why not create your own?
If you work on or around construction sites, you have probably seen small coloured tags attached to scaffolds. These are Scafftags, and they are far more important than many people realise. A Scafftag is not just a label or decoration. It is a visual inspection record that tells workers at a glance whether a scaffold is safe to use, who inspected it, when it was last checked, and when the next inspection is due.
Understanding what Scafftags mean and when they must be updated is essential for anyone managing scaffolds or working at height. Get it wrong and you risk enforcement action, serious injuries, or prohibition notices that shut down entire projects. Get it right and you create clear, visible safety systems that protect workers and demonstrate professional competence. Let me explain exactly what Scafftags are, what the different colours mean, and when they must be updated to maintain compliance and safety.
A Scafftag is a proprietary inspection tag system developed specifically for scaffold safety management. While the term “Scafftag” is a brand name, it has become widely used across the UK construction industry to describe any scaffold inspection tag system that uses colour coded status indicators to communicate scaffold safety information.
The purpose of a Scafftag is straightforward: to provide visible, immediate confirmation that a scaffold has been inspected by a competent person and is safe for use. Rather than requiring workers to check written inspection records filed in site offices, Scafftags display critical safety information directly on the scaffold structure where decisions about use are made.
This visible communication system addresses a fundamental problem in construction safety. Workers arriving on site, contractors from other trades, or temporary staff may not know the inspection history of scaffolds they encounter. Without visible status indicators, they cannot verify whether structures are safe, incomplete, or awaiting inspection. Scafftags solve this problem by making inspection status impossible to miss.
The Work at Height Regulations 2005 require that scaffolds are inspected before first use, after any alteration, after adverse weather, and at least every seven days. The regulations also require that inspection results are recorded and made available to workers. While the regulations do not mandate any specific tag system, Scafftags have become the industry standard method for demonstrating compliance with these information duties.
For comprehensive detail on why scaffold inspection signs are essential, see our guide on whether you need scaffold inspection signs on every job.
Scafftags use a colour coded system that allows workers to assess scaffold status instantly without reading detailed text or checking paperwork. Understanding what each colour means is essential for safe scaffold use.
A green Scafftag indicates that the scaffold has been inspected by a competent person, found to be complete and safe, and is approved for use. Workers seeing a green tag know they can access and work on the scaffold without restriction, provided they stay within stated load limits and follow standard safe working practices.
Green tags show the inspection date, inspector name or identification number, next inspection due date, and any load restrictions or special conditions. This is the only colour tag that authorises normal scaffold use.
A red Scafftag indicates the scaffold is unsafe, incomplete, or awaiting inspection and must not be used under any circumstances. Red tags are attached to scaffolds during erection before completion, after significant alterations, following identification of defects, or when structures are being dismantled.
Workers must never access scaffolds displaying red tags regardless of how complete or safe they appear. Only competent scaffolders conducting construction, modification or inspection work should be present on scaffolds with red tags, and even then only when specifically authorised.
Some Scafftag systems include amber or yellow tags indicating restricted or conditional use. These tags show the scaffold has been inspected but has limitations or special requirements. For example, a scaffold might be approved for light duty only, restricted to specific trades, or limited to certain platform levels while other areas remain incomplete.
Amber tags should state the specific restrictions clearly so workers understand exactly what is and is not permitted. If restrictions are complex or ambiguous, consider using red tags with “Do Not Use” messaging until conditions allow full approval with green tags.
For comprehensive guidance on all types of scaffold signage requirements, see our article on what signs should be displayed on scaffolding.
Effective Scafftags display specific information that allows workers to verify scaffold safety and identify who to contact with concerns or questions.
Inspector Details
The name, initials or identification number of the competent person who conducted the inspection. This accountability ensures inspections are traceable and that workers know who approved the scaffold for use.
Inspection Date
The date when the most recent inspection was completed. This shows workers that checks are current and have not lapsed beyond required intervals.
Next Inspection Due
The date when the next inspection must be completed, typically seven days from the last check. This forward looking information allows supervisors to schedule inspections before deadlines lapse and helps workers identify scaffolds with expired inspection cycles.
Scaffold Reference or Location
On sites with multiple scaffolds, reference numbers or location identifiers link physical tags to written inspection records and scaffold registers. This connection supports compliance audits and incident investigations.
Load Limits and Restrictions
Maximum safe working loads, scaffold classification (light, general, heavy or special duty), and any specific restrictions such as “No Storage Above Platform Level” or “Maximum 2 Persons at Any Time.” This information prevents overloading and misuse.
Special Conditions or Warnings
Notes about overhead hazards, fragile surfaces nearby, restricted access routes, or other site specific conditions that affect safe scaffold use.
Well designed Scafftags present this information clearly with high contrast text, durable materials that survive weather exposure, and layouts that prioritise the most critical details. For guidance on selecting appropriate materials, explore our signs.
Understanding when to update Scafftags is just as important as knowing what they mean. Outdated tags create dangerous situations where workers believe scaffolds are safe based on old inspection information when conditions may have changed significantly.
The Work at Height Regulations 2005 require scaffold inspections at least every seven days. Each time a competent person conducts one of these routine inspections, the Scafftag must be updated to show the new inspection date and the next check due date. This creates a visible record that inspections are happening on schedule.
Sites that conduct inspections but fail to update tags create confusion and compliance failures. Workers cannot distinguish between scaffolds inspected yesterday and those last checked three weeks ago if tags show outdated information. HSE inspectors viewing expired tags will assume inspection cycles have lapsed regardless of what written records claim.
Whenever scaffolds are extended, reconfigured, have components added or removed, or undergo any modification that could affect stability or safety, they must be inspected before re-use. The Scafftag must be updated to reflect this new inspection, typically by replacing the existing tag with a fresh one showing the post-alteration inspection details.
Attempting to update dates on existing tags without conducting fresh inspections is a serious compliance failure. The inspection requirement is triggered by the alteration, not by the passage of seven days, so tags must reflect the actual inspection sequence.
High winds, heavy snow, prolonged freezing conditions or severe storms can damage scaffolds or affect their stability. Following such weather events, scaffolds must be inspected before continued use, and Scafftags updated to show the post-weather inspection has been completed.
The definition of “adverse weather” depends on scaffold design, location and exposure. Sheltered scaffolds in urban areas may withstand conditions that compromise exposed coastal or hilltop installations. Competent persons should use judgement to determine when weather events warrant additional inspections beyond the routine seven day cycle.
When scaffolding contractors complete initial scaffold erection, they should attach a green Scafftag showing the handover inspection details. This tag confirms the scaffold is complete, meets design specifications, and has been approved for use. Without this initial green tag, scaffolds remain under red tag status as incomplete structures awaiting inspection.
If routine inspections, worker reports or incident investigations identify scaffold defects, red tags should immediately replace green tags to prevent continued use. Once defects are rectified, competent persons must inspect the scaffold to verify repairs are adequate, then update to green tags authorising resumed use.
The tag update cycle following defect identification is: green tag removed, red tag installed, defect rectified, inspection conducted, new green tag installed. Skipping any step in this sequence creates dangerous situations where workers may access scaffolds believing repairs have been inspected and approved when they have not.
For detail on the serious consequences of missing or outdated scaffold tags, read our article on whether missing scaffold signs can lead to site shutdowns.
Not everyone on site has authority to update Scafftags. Only competent persons who have conducted scaffold inspections can update tags, and their updates must accurately reflect inspection findings.
A competent person for scaffold inspection purposes is someone with sufficient training, experience and knowledge to identify whether scaffolds are safe for use, whether they comply with design specifications, and whether any defects or dangerous conditions exist. This typically means qualified scaffolders with additional inspection training, dedicated scaffold inspectors, or experienced site managers who have undertaken formal scaffold inspection courses.
Site labourers, general operatives or supervisors without specific scaffold competence cannot conduct inspections or update tags regardless of how experienced they are in other construction trades. The consequences of incompetent inspections are too serious to allow informal delegation of inspection duties to unqualified personnel.
Competent persons conducting inspections should carry supplies of blank Scafftags, permanent markers and fixings so they can update tags immediately after completing inspections. Delays between inspection and tag updates create periods where scaffold status is unclear, potentially allowing use of structures that have not yet been formally approved.
For sites implementing comprehensive scaffold safety systems, see our guidance on scaffold safety signage rules every site should follow.
Even sites with good intentions make preventable mistakes with Scafftag systems. Understanding common errors helps you avoid them.
Tags Updated Without Actual Inspections
The most serious error is updating inspection dates on tags without conducting genuine inspections. This creates false records suggesting compliance when scaffolds may be unsafe. Always ensure inspections precede tag updates, never the reverse.
Illegible or Weather Damaged Tags
Tags written with non-permanent markers fade quickly in rain or sunlight. Tags made from poor quality materials tear, crack or become illegible within days. Use waterproof permanent markers and weatherproof tag materials designed for outdoor construction use.
Tags Positioned Where Workers Cannot See Them
Tags attached to scaffold bases, tucked behind standards, or positioned facing away from approach routes provide no benefit. Position tags at primary access points where workers will see them before ascending, typically at eye level on scaffold standards or access gates.
Single Tags on Large or Complex Scaffolds
Scaffolds with multiple access points require tags at each entry so workers cannot access the structure without seeing current inspection status. A single tag at one location leaves other access points uncontrolled.
Outdated Tags Left in Place After Updates
When updating tags, remove and dispose of old tags to prevent confusion. Leaving multiple tags with different dates on the same scaffold creates ambiguity about which inspection is current.
No System for Tracking Tag Supplies
Inspectors arriving for seven day checks without blank tags cannot update signage properly. Maintain adequate stocks of Scafftags at site level and ensure inspectors know where to find them.

Successful Scafftag implementation requires more than buying tags and handing them to inspectors. It requires systematic approaches that embed tag updates into routine scaffold management.
Establish clear procedures specifying who conducts inspections, how often, what gets inspected, and how tags are updated. Provide competent inspectors with adequate supplies of tags, permanent markers and fixings. Train all site personnel on what tag colours mean and the importance of checking tags before using scaffolds.
Maintain scaffold registers tracking all structures on site, inspection due dates, and tag status. Use these registers to trigger inspections before seven day deadlines lapse and to verify that tags remain current and visible during site audits.
Conduct weekly compliance checks verifying that all scaffolds display current green tags or legitimate red tags for incomplete structures. Treat missing or expired tags as urgent defects requiring immediate rectification, not minor administrative oversights.
All scaffold tags should comply with ISO 7010 standards where applicable, using standardised symbols and colours that ensure universal recognition across multilingual workforces.

Scafftags are simple tools that serve a critical safety function. They transform abstract inspection requirements into visible status indicators that workers can verify instantly. Green means safe, red means unsafe, and the inspection date tells workers whether checks are current or overdue.
Update Scafftags every seven days during routine inspections, after any alteration or adverse weather, and whenever scaffold status changes. Only allow competent persons to conduct inspections and update tags. Position tags where workers will see them before accessing scaffolds. Use durable materials that survive construction environments.
