TG30 Compliance Sheets Explained

As system scaffolds become increasingly common across construction projects, many contractors are being asked to provide evidence that their scaffold complies with recognised industry guidance. A TG30 Compliance Sheet is one way of demonstrating that a system scaffold configuration falls within the scope of TG30:24 and the relevant manufacturer's guidance. Understanding what these documents contain—and when they can be used—is important for scaffold contractors, temporary works coordinators and site managers alike.

Quick Answer

A TG30 Compliance Sheet is a document that demonstrates a system scaffold complies with TG30:24 guidance and the relevant manufacturer’s requirements. It provides evidence that the scaffold falls within recognised industry guidance and does not require a bespoke scaffold design.

What Is a TG30 Compliance Sheet?

A TG30 Compliance Sheet is a document used to demonstrate that a system scaffold configuration complies with TG30:24 guidance and the manufacturer’s approved scaffold arrangements.

Like a TG20 Compliance Sheet for tube and fitting scaffolds, it provides evidence that a scaffold falls within recognised industry guidance and can be erected without requiring a bespoke scaffold design.

A compliance sheet is not a design drawing or structural calculation. Its purpose is to demonstrate compliance with established guidance.

What Information Does a TG30 Compliance Sheet Contain?

A TG30 Compliance Sheet typically includes details of the scaffold configuration being assessed, together with key compliance information such as dimensions, loading classifications, tie requirements and other parameters relevant to the scaffold system being used.

The exact content will vary depending on the scaffold manufacturer and configuration, but the objective remains the same: demonstrating that the scaffold falls within recognised compliance limits.

When Can a TG20 Compliance Sheet Be Used?

System Scaffold Type

Tied Independent Scaffold

Birdcage Scaffold

System Stair tower

Access Scaffold

Loading Platform

Bridged Scaffold

Suspended Scaffold

Temporary Roof Scaffold

When Is a TG30 Compliance Sheet Not Enough?

A compliance sheet cannot be used where the scaffold falls outside TG30 guidance or manufacturer limitations.

This may include:

  • Large bridging arrangements
  • Significant cantilevers
  • Complex temporary roofs
  • Heavy loading conditions
  • Non-standard configurations
  • Suspended scaffolds
  • Unusual tie arrangements

In these situations, a scaffold design may be required to demonstrate structural adequacy.

TG30 Compliance Sheets vs Scaffold Designs

TG30 Compliance Sheet

Demonstrates Compliance with TG30:24

Used for Standard scaffold configurations

Based on recognised guidance

No Bespoke Calculations Required

Suitable for Compliant Scaffolds only

Scaffold Design

Provides bespoke Engineering Assessment

Used for Non-standard scaffolds

Produced by a Scaffold Designer

Includes Bespoke structural calculations

Required for Scaffolds that fall outside of Guidance

Why Was TG30 Introduced?

Before a compliance sheet can be produced, the scaffold must be assessed against TG20 requirements.

This includes verifying:

  • Scaffold geometry
  • Platform loading
  • Tie arrangements
  • Bracing requirements
  • Wind loading assumptions
  • Access arrangements

Many scaffold companies now use digital compliance tools to verify compliance before progressing with projects, helping to reduce risk and improve consistency.

The Relationship Between TG20 and TG30

TG20 and TG30 perform similar functions but apply to different scaffold types.

Guidance Scaffold Type
TG20:21 Tube and Fitting Scaffolds
TG30:24 System Scaffolds

Both guidance documents help determine whether a scaffold can be considered compliant without requiring a bespoke design.

CADS and the Development of Scaffold Compliance Guidance

CADS has supported the scaffolding industry for decades through engineering expertise, software development and collaboration with industry bodies.

The engineering and software teams behind the SMART Scaffolder product range have also played a significant role in the development of both TG20 and TG30 guidance, providing a unique understanding of how scaffold compliance guidance is developed and applied in practice.

This experience helps ensure that CADS remains at the forefront of digital innovation within the scaffolding sector.

Frequently Asked Questions

Is a TG30 Compliance Sheet a scaffold design?

No. A TG30 Compliance Sheet demonstrates compliance with TG30 guidance and manufacturer requirements. It does not replace a scaffold design where one is required.

Does TG30 apply to tube and fitting scaffolds?

No. TG30 applies to system scaffolds. Tube and fitting scaffolds are covered by TG20:21.

What happens if a scaffold falls outside TG30?

The scaffold may require a bespoke design prepared by a competent scaffold designer.

Can all system scaffolds use TG30?

Only where the scaffold configuration falls within TG30 guidance and the relevant manufacturer’s approved arrangements.

Who uses TG30 Compliance Sheets?

They are commonly used by scaffold contractors, temporary works coordinators, site managers and principal contractors to demonstrate scaffold compliance.

Risks of Assuming a Scaffold Doesn't Need a Design

Incorrectly treating a scaffold as TG20 or TG30 compliant can result in:

Delays on site

Failed inspections

Additional costs

Project disruption

Increased liability

Safety risks

For this reason, scaffold contractors should always verify compliance before erection begins.
