Complete Scaffolding Inspection Checklist for UK Construction 2026

Scaffolding collapses and falls from scaffolding remain among the leading causes of serious injury and death on UK construction sites. Regular, thorough inspections are not just a legal requirement. they are essential to protecting lives. This guide provides a comprehensive inspection checklist aligned with current UK regulations and industry best practice for 2026.

Legal Requirements for Scaffolding Inspections

Scaffolding inspections in the UK are governed by several pieces of legislation that every site manager and scaffolding contractor must understand.

Work at Height Regulations 2005

The Work at Height Regulations require that scaffolding is inspected:

• Before first use after erection
• After any event likely to have affected stability (strong winds, impact damage, subsidence)
• At regular intervals not exceeding 7 days

Inspections must be carried out by a competent person, and the results must be recorded in a scaffold inspection report. Reports must be kept on site until the scaffold is dismantled, and then retained for 3 months.

CDM Regulations 2015

The CDM Regulations place duties on the principal contractor to ensure that scaffolding is erected, used, and maintained safely, and that all necessary inspections are carried out.

NASC Guidance

The National Access and Scaffolding Confederation (NASC) publishes technical guidance notes (TG20, SG4) that provide detailed standards for scaffolding design, erection, and use. While not law, NASC guidance is widely accepted as representing industry best practice.

Who Can Inspect Scaffolding?

A scaffolding inspector must be a "competent person". someone with sufficient training, knowledge, and experience to identify defects and hazards. This typically means:

• CISRS (Construction Industry Scaffolders Record Scheme) qualified scaffolders for the initial inspection after erection
• Site managers or supervisors with appropriate scaffolding inspection training for the 7-day inspections
• NASC recommends that the inspector holds at least CISRS Part 1 scaffolder qualification or CISRS Scaffold Inspector training

The Complete Inspection Checklist

Use this checklist for every scaffolding inspection. Document the findings and retain the records.

1. Foundation and Base

• Base plates properly positioned on firm, level ground
• Sole boards provided where ground is soft or uneven
• No undermining of foundations by excavation or water erosion
• Adjustable base jacks not extended beyond safe limits
• No visible settlement or movement of standards

2. Standards (Vertical Tubes)

• All standards are plumb (vertical within acceptable tolerance)
• No bent, damaged, or corroded tubes
• Correct spacing maintained throughout
• All joints are staggered (not at the same level)
• Spigot joints correctly made with internal sleeves

3. Ledgers (Horizontal Tubes)

• All ledgers are level and properly connected to standards
• No missing or disconnected ledgers
• Correct spacing maintained at each lift height
• No damaged or bent tubes

4. Bracing

• Diagonal bracing in place as per design
• Ledger bracing fitted where required
• Plan bracing at appropriate levels
• All bracing couplers tight and secure
• No missing bracing members

5. Platforms and Decking

• All working platforms are fully boarded with no gaps exceeding 25mm
• Boards are in good condition. no splits, warping, or excessive wear
• Boards are properly supported with no excessive overhang (maximum 150mm)
• Platform width adequate for the intended work (minimum 600mm for access, wider for work platforms)
• No debris, tools, or materials creating trip hazards
• Trap doors or access gates close properly

6. Guard Rails and Toe Boards

• Top guard rails fitted at all open edges at 950mm minimum height
• Mid rails fitted to prevent gaps exceeding 470mm
• Toe boards fitted at 150mm minimum height
• Brick guards or mesh panels where there is a risk of materials falling
• All guard rail couplers tight and secure
• No guard rails or toe boards missing or removed

7. Access

• Internal ladders provided at each lift, properly secured
• Ladder access gates fitted and functional
• Ladders extend at least 1 metre above the platform
• Staircase towers in good condition where provided
• Access routes clear and unobstructed

8. Ties and Anchors

• All ties present as per the scaffold design
• Ties secure and undamaged
• No ties removed without authorisation and temporary replacement
• Reveal ties wedged tight and not loose
• Through ties properly installed and tightened
• Tie pattern compliant with TG20 or specific design

9. Couplers and Fittings

• All couplers are the correct type for their application
• Couplers are tight (check by hand. should not rotate freely)
• No damaged, cracked, or defective couplers
• Swivel couplers used only where permitted by the design

10. Loading

• Scaffold is not overloaded beyond its design capacity
• Materials are not stacked excessively on platforms
• Loading bay signs clearly displayed where applicable
• No unauthorised modifications to the scaffold that could affect its load capacity

11. Signage and Information

• Scaffold tag system in place (green = safe to use, red = do not use)
• Scaffolder's handover certificate displayed
• Load capacity signs displayed at each level
• Incomplete scaffold areas clearly marked and access prevented

12. General Condition

• Sheeting or netting secure and not creating wind-loading issues
• No unauthorised modifications to the scaffold
• Scaffold clear of excessive debris and waste materials
• No contact with overhead power lines or other services
• Adequate clearance from moving vehicles

After the Inspection

Once your inspection is complete:

1. Record findings. Complete the inspection report immediately, noting any defects found
2. Classify defects. Is the scaffold safe to use, safe with restrictions, or must not be used?
3. Take action. Report defects to the scaffolding contractor for rectification. Critical defects require immediate exclusion from the scaffold
4. Update the scaffold tag. Ensure the tag reflects the current inspection status
5. Retain records. Keep inspection reports on site and store digitally for long-term access

Digital inspection tools like FORGE Command allow you to complete scaffold inspections on your phone, attach photos of any defects, and maintain a permanent digital record that is instantly available during audits or investigations.

When to Stop Work

If any of the following are found during inspection, the scaffold must not be used until rectified:

• Missing or disconnected ties
• Missing guard rails at working platforms
• Significant structural damage to tubes or fittings
• Foundation settlement or movement
• Scaffold not built to the approved design
• Overloading beyond design capacity

Never allow work to continue on a scaffold that has failed inspection. The risk to life is too great, and the legal consequences of knowingly allowing unsafe scaffolding to be used are severe.
