What Is TG20 Compliance and Why Does It Matter?

Understanding TG20 compliance for scaffolding projects

TG20 compliance is a widely recognised system used within the scaffolding industry to help demonstrate that certain scaffold structures have been designed and erected in accordance with recognised standards.

For contractors, scaffolders and site managers, understanding TG20 compliance is important because it helps confirm that a scaffold structure is suitable for its intended purpose and has been properly considered from a safety perspective.

Statutory Scaffold Inspections provides independent scaffold inspections for construction projects across the South West, helping clients maintain safe working environments and accurate inspection records.

What is TG20 compliance?

TG20 is a guidance system developed by the National Access and Scaffolding Confederation (NASC) to assist with the safe design and erection of common scaffolding structures.

The system provides standardised guidance for scaffolds that fall within recognised parameters, helping users determine whether a scaffold can be considered compliant without requiring a bespoke design.

TG20 compliance is commonly used for standard scaffold configurations where the requirements of the guidance are met.

Why is TG20 compliance important?

TG20 compliance helps provide confidence that a scaffold has been planned and constructed using recognised industry guidance.

Benefits include:

Supporting safer scaffold design and erection
Helping demonstrate compliance with recognised guidance
Providing a consistent approach to common scaffold structures
Assisting contractors and site managers with scaffold management

It is important to remember that TG20 compliance does not remove the need for regular scaffold inspections.

Does TG20 compliance replace scaffold inspections?

No. A TG20 compliance sheet or confirmation that a scaffold is compliant does not replace the need for regular inspections.

Even when a scaffold has been erected in accordance with TG20 guidance, it must still be inspected throughout its use.

Scaffolding can be affected by:

Weather conditions
Site activities
Alterations
Damage
Changes in how the scaffold is being used

Regular inspections help ensure that the scaffold remains safe after it has been erected.

What is checked during a scaffold inspection?

A scaffold inspection involves assessing the actual condition of the scaffold on site.

Checks may include:

Overall stability of the scaffold
Condition of components and fittings
Scaffold ties and bracing
Access arrangements
Working platforms
Guardrails and toe boards
Changes or damage since erection

An inspection focuses on whether the scaffold remains safe and suitable at the time of checking.

Who uses TG20 compliance?

TG20 compliance is commonly used by:

Scaffold contractors
Construction companies
Principal contractors
Site managers
Developers

It provides a recognised way of demonstrating that standard scaffolds have been considered against industry guidance.

The importance of independent scaffold inspections

While TG20 compliance provides valuable guidance for scaffold design and erection, independent inspections remain an important part of ongoing scaffold safety management.

An independent scaffold inspection provides an impartial assessment of the scaffold condition and helps identify any issues that may have developed after erection.
