Scaffolding plays a critical role in construction, providing a safe platform for workers to perform tasks at height. However, ensuring the safety of workers and the public requires strict adherence to scaffolding rules and regulations UK. The most relevant legislation for scaffolding includes the Work at Height Regulations 2005 and the Provision and Use of Work Equipment Regulations (PUWER) 1998. The industry-led National Access and Scaffolding Confederation (NASC) guidance includes TG20:21 and various SG guidance, along with manufacturers’ guidance for the scaffold type, whether tube and fitting, modular, or other systems.
This comprehensive guide outlines the essential scaffolding regulations, UK standards, and best practices for construction businesses, focusing on compliance with UK guidelines and HSE requirements. Understanding and implementing these regulations is not just about legal compliance; it is about protecting lives, preventing serious injuries, and safeguarding your business from prosecution and substantial fines.

UK Scaffolding Safety Statistics: Why Compliance Matters
Falls from height remain the leading cause of death in UK construction. According to HSE statistics, falls from height account for 40% of all construction fatalities, with 29% of major injuries involving scaffolding-related incidents. The financial consequences are severe, with businesses facing average fines of £180,000 to £450,000 for serious breaches, and company directors potentially facing up to two years imprisonment.
These statistics underscore why compliance with scaffolding regulations UK is a legal and moral obligation. At CHSP, we provide comprehensive scaffolding risk assessment services across the Midlands, helping businesses meet these critical obligations and protect their workforce.
Understanding Scaffolding Regulations in Construction
Scaffolding enables workers to access areas that would otherwise be out of reach, supporting workers, tools, and materials safely at height. However, safety benefits are only realised when scaffolding is erected and used correctly according to HSE scaffolding regulations. The Work at Height Regulations 2005 set clear legal requirements for planning, supervising, and executing all work at height.
Our IOSH-certified consultant has over 15 years’ experience helping construction businesses achieve full compliance with scaffolding regulations UK, protecting workers and businesses from legal penalties and HSE prosecution.
Common Uses and Risks
Scaffolding is essential for new construction, renovations, event setups, infrastructure projects, and industrial installations. Workers safely access elevated areas for bricklaying, painting, roofing, repairs, and maintenance work across these sectors.
However, poorly constructed scaffolding poses serious risks. Falls from height occur when guardrails are missing, bracing is inadequate, or platforms become unstable. Falling objects can injure workers below, making safety nets, brick guards, and toe boards essential. Structural collapses from inadequate securing or overloading can cause catastrophic injuries or fatalities. Scaffolds must be tied to buildings according to NASC TG20:21 guidance.
Understanding these risks emphasises the importance of following scaffolding regulations and best practices. Similar to our COSHH risk assessments and site safety inspections, comprehensive planning is essential for all scaffolding projects.
Basic Scaffolding Regulations You Must Follow
Several key scaffolding requirements must be followed to ensure safety and compliance under the Work at Height Regulations 2005.
Competent Personnel
Only trained and competent individuals may erect, alter, or dismantle scaffolding. This is a legal requirement under the scaffolding rules and regulations UK. Companies must verify that scaffolders hold current, valid CISRS (Construction Industry Scaffolders Record Scheme) cards.
CISRS qualification levels include:
Trainee Scaffolder – Works under direct supervision, learning basic tasks (0-6 months experience)
Scaffolder (Part 1) – Erects standard tube and fitting scaffolds up to 12 metres with periodic supervision (6-18 months experience)
Advanced Scaffolder (Part 2) – Works on complex scaffolds, interprets designs and TG20:21 compliance sheets independently (2+ years experience)
CISRS Supervisor – Supervises teams, conducts inspections, signs handover certificates (3+ years experience)
Advanced Scaffold Inspector – Conducts full statutory inspections, verifies complex designs (5+ years experience)
All CISRS cards must be renewed every five years through re-registration. Companies must maintain records of scaffolders’ qualifications and ensure competent CISRS Supervisors oversee all work. Failure to verify qualifications can result in HSE prosecution with significant consequences.
Licensing Requirements
Scaffolding placed on public pavements or highways requires a license from your local authority under the Highways Act 1980. The scaffolding contractor or principal contractor typically obtains this license, but clients must ensure proper documentation is in place. Erecting scaffolding on public land without a license is a criminal offence, causing potential project delays and enforcement action.

Regular Scaffolding Inspections
Scaffolding must be inspected regularly under Regulation 12 of the Work at Height Regulations 2005. These are legal requirements, not optional procedures.
When Inspections Are Required
Before first use – A handover inspection by a CISRS Supervisor or Advanced Scaffold Inspector verifies the scaffold is erected correctly and safe for intended use. A handover certificate must be issued before any work takes place.
Every seven days – Statutory inspections ensure the scaffold has not deteriorated, all components remain secure, and safety features remain effective. Inspections must cover foundations, standards, ledgers, transoms, ties, bracing, guardrails, toe boards, and access points.
After alterations – Any modifications require inspection before the modified scaffold is used. This includes adding or removing lifts, changing configuration, relocating ties, or modifying access.
After adverse weather – High winds over 40mph, heavy rain, snow, or ice require inspection before work resumes. Extreme weather can loosen fittings, displace components, or create hazardous surfaces.
All inspections must be documented in writing, with records retained for at least three months. Records must include inspection date and time, scaffold location, inspector name and qualifications, defects found, and remedial action taken.
Our ongoing retainer service provides regular scaffolding inspection schedules, compliance monitoring, and record-keeping support to ensure year-round compliance.
Working Safely at Height
The Work at Height Regulations 2005 require duty holders to do all reasonably practicable to prevent falls. This means following a hierarchy of control measures, with collective protection always prioritised over personal protective equipment.
Collective Protection (Always First)
Collective protection measures protect everyone without requiring individual action. These include:
-
Guardrails – Main guardrail at 950-1000mm height, intermediate guardrail, and toe boards, minimum 150mm high. Guardrails are mandatory on all working platforms above 2 metres where there is a fall risk.
-
Safety netting – Catches falling objects and provides secondary fall protection
-
Toe boards and brick guards – Prevent materials from falling
-
Debris netting – Essential on external scaffold faces near public areas
HSE guidance on guardrails specifies these requirements. Installation and maintenance must be verified during scaffold inspections, with deficiencies remedied immediately.
Personal Protection (Last Resort Only)
Personal protective equipment (PPE) should only be used when collective protection is not practicable. Safety helmets protect from head injuries and must comply with EN 397 standards. High-visibility clothing ensures workers are visible to others on site. Safety harnesses may be required during erection and dismantling when collective protection cannot yet be installed, but harnesses should never substitute for guardrails on completed scaffolds.
Employers must provide PPE at no cost and train workers in correct use, inspection, fitting, and defect reporting.
Mobile Towers: Alternatives to Scaffolding
Mobile access towers offer flexibility for shorter-duration tasks or work requiring frequent repositioning. The industry-recognised standards are provided by PASMA (Prefabricated Access Suppliers’ and Manufacturers’ Association).
Safety Requirements for Towers
Mobile towers must have stabilisers or outriggers deployed when in use, toe boards minimum 150mm high, guardrails meeting the same standards as scaffolding (top rail 950-1000mm, mid-rail, toe boards), internal ladder access (external climbing is prohibited), and castors with effective brakes locked during use.
Towers must be inspected after erection before first use and regularly thereafter, particularly after modifications or adverse weather. PASMA training is essential for anyone erecting, modifying, or using mobile towers. The HSE and PASMA advise against using harnesses on mobile towers as primary fall protection because falls can cause the tower to overturn. Complete guardrails provide effective collective protection. Our risk assessment and method statement services include comprehensive RAMS for mobile tower operations.
Scaffolding Standards and Guidelines
The scaffolding standards in the UK are set by the National Access and Scaffolding Confederation (NASC), providing comprehensive guidelines that support legal requirements. NASC guidance documents are widely recognised throughout the industry and referenced by the HSE in enforcement proceedings.
SG4: Preventing Falls in Scaffolding Operations
SG4 (Safety Guidance 4) offers detailed guidance on preventing falls during scaffolding erection, alteration, and dismantling. SG4 addresses the most dangerous phases when structures are incomplete and full collective protection cannot yet be provided. The guidance covers safe working methods, guardrail systems (Through the Trap and Advance Guardrail), risk assessment requirements, and competence and training needs. SG4 emphasises that collective protection should always be prioritised over personal protective equipment.
TG20:21: Technical Guidance for Tube and Fitting Scaffolds
TG20:21 provides comprehensive guidance on scaffold design, including loading tables for different configurations, standard design configurations that can be used without bespoke engineering, tie patterns and bracing requirements, and foundation and base plate specifications.
For standard scaffold configurations, TG20:21 compliance sheets can be used instead of bespoke designs. However, where scaffolds fall outside TG20:21 parameters due to complex designs, unusual loading, significant height, or uncommon configurations, a bespoke design by a qualified scaffold designer is mandatory.
Scaffolding Higher than 2m: Critical Safety Requirements
Scaffolding higher than 2 meters requires comprehensive safety features under the Work at Height Regulations 2005. The two-metre threshold triggers enhanced protective requirements because falls from this height are likely to cause major injuries or fatalities.
Essential Safety Features
Guardrails and Edge Protection – Main guardrail at 950-1000mm above the platform, intermediate guardrail, and toe boards, minimum 150mm high on all working platforms and edges.
Secure Joints and Bracing – All couplers tightened to correct torque with diagonal, ledger, and facade bracing according to design requirements.
Ties to Building Structure – Tied as per TG20:21 or bespoke design, typically at four-metre intervals horizontally and vertically.
Loading Capacity Marking – Load class clearly displayed (Class 3: 75kg/m² light duty, Class 4: 150kg/m² general purpose, Class 5: 200kg/m² heavy duty, Class 6: 300kg/m² masonry).
Safe Access and Egress – Properly secured ladders extending one metre above platform level, or staircase access for larger scaffolds.
Regular Seven-Day Inspections – By a competent person with records kept for at least three months.
The British Standard Scaffolding regulations (BS EN 12811), NASC TG20:21, and HSE guidance HSG150 provide detailed requirements.
Scaffolding Risk Assessments and Method Statements
Site-specific Scaffold Risk Assessments and Method Statements (RAMS) must identify hazards and outline risk mitigation steps before work begins. These documents must be communicated to all workers involved in erecting, using, or dismantling scaffolds.
The risk assessment must identify hazards, including falls from height, falling objects, structural collapse, manual handling injuries, adverse weather effects, contact with overhead services, and working near traffic. For each hazard, control measures must follow the hierarchy of control: elimination, risk reduction through design, collective protection, administrative controls, and personal protective equipment as a last resort.
The method statement details how work will be carried out safely, including erection and dismantling sequences, equipment and materials, scaffolder numbers and competence levels, supervision and inspection arrangements, measures to protect workers during erection, protection for other workers and the public, access and egress arrangements, loading and unloading procedures, and emergency procedures.
For complex scaffolds, a bespoke design by a qualified scaffold designer may be required. TG20:21 compliance sheets can be used for standard configurations within guidance parameters. Our risk assessment and method statement services provide comprehensive RAMS ensuring full compliance with HSE guidance and Work at Height Regulations 2005.
Frequently Asked Questions About Scaffolding Regulations UK
What are the main scaffolding regulations in the UK?
The primary scaffolding regulations in the UK are the Work at Height Regulations 2005 and PUWER 1998. These establish legal duties for planning, organising, and performing work at height. The regulations require proper planning by competent people, appropriate competence or supervision for those involved, risk assessment with appropriate control measures, proper selection, inspection, and maintenance of equipment, and identification and protection of fragile surfaces.
Industry guidance from NASC, including TG20:21 and SG4, provides detailed technical standards supporting legal compliance.
Do I need a license to erect scaffolding in the UK?
If scaffolding is erected on public pavements, highways, or public spaces, you need a license from your local authority under the Highways Act 1980. The scaffolding contractor or principal contractor typically obtains this license. The application requires detailed plans, pedestrian arrangements, traffic management measures, lighting and signing, and insurance documentation.
Erecting scaffolding on public highways without a license is a criminal offence resulting in immediate removal requirements, prosecution and fines, and project delays. For scaffolding on private property with no public land encroachment, no local authority license is required, but you must comply with all Work at Height Regulations 2005 requirements.
What qualifications do scaffolders need in the UK?
Scaffolders must hold valid CISRS cards demonstrating recognised training and competence. CISRS levels include Trainee Scaffolder (direct supervision required), Scaffolder Part 1 (standard scaffolds up to 12m), Advanced Scaffolder Part 2 (complex scaffolds independently), CISRS Supervisor (team supervision and inspections), and Advanced Scaffold Inspector (statutory inspections and complex designs).
CISRS cards must be renewed every five years through re-registration, which includes continuing professional development evidence and updated health, safety, and environmental testing. Employers must verify cards are in date and ensure competent CISRS Supervisors oversee all work.
How often must scaffolding be inspected in the UK?
Under Work at Height Regulations 2005, scaffolding must be inspected before first use (handover inspection with certificate), at least every seven days while in use (statutory inspection by competent person), after alterations or modifications (before the modified scaffold is used), and after adverse weather (winds over 40mph, heavy rain, snow, or ice).
Inspection records must be kept for at least three months and include the inspection date and time, scaffold location, inspector name and qualifications, defects found, remedial action taken, and inspector signature.
What is NASC TG20 and SG4 scaffolding guidance?
NASC TG20:21 is the comprehensive technical guide for tube and fitting scaffolds, including loading tables, standard configurations, tie patterns, foundation specifications, and design guidance. TG20:21 compliance sheets can be used for standard configurations instead of bespoke designs. Where scaffolds fall outside TG20:21 parameters, bespoke design by a qualified designer is mandatory.
SG4 focuses on preventing falls during erection, alteration, and dismantling. It covers safe working methods, guardrail systems, risk assessment requirements, and competence needs. Both documents are industry-recognised standards supporting Work at Height Regulations 2005 compliance.
What safety requirements apply to scaffolding higher than 2m?
Scaffolding higher than 2 meters requires guardrails (main rail 950-1000mm, mid-rail, toe boards 150mm minimum), secure joints and adequate bracing (all couplers correctly tightened), ties to building structure (typically every 4m horizontally and vertically), clearly marked loading capacity (Class 3, 4, 5, or 6), safe access and egress (secured ladders or staircases), and regular seven-day inspections by competent person.
These requirements are detailed in NASC TG20:21, SG4, and HSE guidance HSG150.
Who is responsible for scaffolding safety on a construction site?
Under the Work at Height Regulations 2005 and CDM Regulations 2015, responsibility is shared. The Principal Contractor coordinates overall site safety and ensures proper scaffolding erection, inspection, and maintenance. The Scaffolding Contractor provides competent CISRS-qualified scaffolders, ensures safe erection according to design, conducts handover inspections, and maintains inspection records. The Client or Employer ensures competent contractors are appointed, adequate time and resources are allocated, and designs are prepared for complex scaffolding. Individual Workers must use scaffolding safely, report defects, not remove safety features, and use required PPE.
All parties can be prosecuted for scaffolding safety failures with substantial fines, imprisonment in serious cases, and reputational damage.
Can I use scaffolding without guardrails if workers wear harnesses?
No. Under the Work at Height Regulations 2005, collective protection such as guardrails must always be prioritised over personal protection such as harnesses. Guardrails are mandatory for scaffolding above 2 meters on all working platforms and edges. Harnesses should only be used during erection and dismantling when guardrails cannot yet be installed, as temporary backup during specific high-risk tasks, or when working on incomplete scaffold lifts with advanced guardrail systems.
Using harnesses as a substitute for guardrails on completed scaffolding is a serious breach resulting in HSE enforcement action. Collective protection protects everyone without relying on individual actions, whereas harnesses require correct fitting and use with multiple opportunities for human error.
Final Thoughts on Safety and Compliance
Adhering to scaffolding regulations UK is fundamentally about ensuring worker and public safety by following industry guidance and legal requirements. Falls from height account for 40% of construction fatalities, with scaffolding-related incidents representing a significant proportion. Every scaffold must be planned, designed where necessary, erected by competent personnel, properly inspected, and maintained throughout its operational life.
By following the scaffolding rules and regulations UK in the Work at Height Regulations 2005, using only competent CISRS-qualified personnel, conducting regular statutory seven-day inspections with proper documentation, and implementing robust risk assessments and method statements, construction businesses can significantly reduce working at height risks and protect their workforce and business from the devastating consequences of scaffold-related accidents.
Whether using traditional tube and fitting scaffolds designed to TG20:21 standards or mobile towers erected according to PASMA guidance, following NASC guidelines with competent supervision and inspection arrangements throughout projects is essential. Investing in professional scaffolding safety management protects lives, maintains legal compliance, and safeguards business reputation and financial stability.
