INSURANCE GUIDE Scaffolding Insurance - what cover scaffolders need in 2026 |
TL;DR
- Scaffolding contractors must hold Employers Liability (EL) insurance of at least GBP 5 million under the Employers Liability (Compulsory Insurance) Act 1969 if they have any employees.
- Public liability (PL) insurance covering at least GBP 5 million is required by most principal contractors and local authority contracts.
- A comprehensive scaffolding package policy typically combines EL, PL, contract works (the scaffold structure itself), tools and plant, and scaffold design liability.
- The Health and Safety Executive (HSE) can inspect EL certificates and issue fines of up to GBP 2,500 per day for non-compliance.
- Scaffold design liability (professional indemnity for TG20 compliance) is a separate cover increasingly required for complex birdcage and suspended scaffold designs.

What Is Scaffolding Insurance?
Scaffolding insurance is a package of insurance covers tailored to the specific risks of scaffolding contractors, whether sole traders, partnerships, or limited companies. Scaffolding work carries above-average risk compared to many trades: operatives work at height, the scaffold structure itself can cause serious injury or property damage if it fails, and materials and plant left overnight on urban sites are vulnerable to theft and vandalism.
A specialist scaffolding package policy assembles multiple covers into a single policy rather than requiring the contractor to arrange each separately. This simplifies the insurance process and ensures there are no gaps between covers that could leave the contractor exposed in the event of a claim.
The Health and Safety at Work etc. Act 1974 and the Work at Height Regulations 2005 impose statutory duties on scaffolding contractors that underpin the insurance requirements. While insurance is not itself required by health and safety law (except for EL), non-compliance with the underlying safety duties can affect claims outcomes and insurability.

What Does a Scaffolding Package Policy Cover?
Employers Liability (EL): Legally compulsory for any scaffolding business with employees. EL covers claims from employees who suffer injury or illness in the course of their employment. The minimum statutory limit is GBP 5 million, though most policies are issued at GBP 10 million. The EL certificate must be displayed at the employer premises or be electronically accessible to employees. HSE inspectors can request to see it and issue fixed penalties of GBP 2,500 per day for each day the business trades without a valid certificate.
Public Liability (PL): Covers claims from third parties (members of the public, property owners, adjacent occupiers) for bodily injury or property damage caused by the scaffolding operation. A scaffold collapse, a tube falling from height, or damage to adjacent glazing from erection activity would all generate PL claims. Standard PL limits for scaffolding are GBP 5 million to GBP 10 million. Many principal contractor supply chain agreements now require GBP 10 million as a minimum.
Contract Works (Scaffold Structure): Covers the scaffold structure itself against accidental damage, fire, storm, flood, vandalism, and theft while erected. This is particularly important for long-duration scaffolds on major refurbishment projects where the erected value of materials and plant is significant. Without contract works cover, the cost of replacing a damaged or stolen scaffold falls entirely on the contractor.
Plant and Tools: Covers scaffolding tubes, fittings, boards, and other equipment against theft from site and accidental damage. Given the high value of scaffold material stock, this is a significant cover. Many policies specify minimum security conditions for plant left on site overnight.
Scaffold Design Liability (Professional Indemnity): Where a scaffolding contractor provides a bespoke scaffold design rather than using a standard TG20 configuration, professional indemnity cover is required for the design element. Increasingly required for complex temporary works designs including birdcage scaffolds, tied fan scaffolds, and suspended systems.
What Is Not Covered?
- Injury to the contractor own operatives caused by their deliberate or reckless breach of safety rules - though EL still covers most workplace injury claims
- Damage to the scaffold caused by the contractor own defective workmanship
- Consequential loss arising from scaffold unavailability - project delays are not covered
- Scaffold design errors where no PI cover is in place
- Theft of materials from unattended sites where minimum security conditions have not been met
How Much Does Scaffolding Insurance Cost?
Scaffolding insurance premiums are higher than most trades due to the elevated risk profile. Indicative 2026 annual costs:
- Sole trader scaffolder, turnover under GBP 100K, PL GBP 5 million + EL + tools: approximately GBP 2,000 to GBP 3,500
- Small limited company, 3-4 operatives, turnover GBP 300K, PL GBP 10 million + EL + contract works + plant: approximately GBP 4,000 to GBP 8,000
- Medium contractor, 10+ operatives, specialist or high-rise work: GBP 10,000 to GBP 25,000
Key factors affecting premiums: number of operatives, annual turnover, type of scaffolding (standard access vs. suspended vs. demolition support), claims history, NASC membership, and CISRS card status of operatives.
NASC membership and CISRS-carded operatives are viewed favourably by insurers and typically reduce premiums. Non-NASC contractors undertaking complex or high-rise scaffolding may find the market significantly more expensive or restricted.

Frequently Asked Questions
Do I need scaffolding insurance as a sole trader?
EL insurance is not legally required for sole traders with no employees. However, PL insurance is required by virtually all principal contractors and clients before any work commences. If you use labour-only subcontractors who are classified as workers rather than genuinely self-employed, EL is also required for them. Most sole trader scaffolders arrange a package combining PL with tools and contract works cover.
What is NASC and does membership affect my insurance?
The National Access and Scaffolding Confederation (NASC) is the trade association for scaffolding contractors. NASC membership requires compliance with SG4 (safety guidance), TG20, and regular safety audits. Most specialist scaffolding insurers view NASC membership favourably and may offer lower premiums or more competitive terms to members. Some insurers restrict cover for certain types of high-risk scaffolding to NASC members only.
Does my PL cover the scaffold if it falls and damages a neighbouring property?
Yes. Public liability insurance covers third-party property damage caused by your scaffolding operations, including scaffold collapse or falling materials. The claim would be brought against your business by the property owner or their insurer, and your PL policy would respond subject to the policy terms and your PL indemnity limit.
What is contract works insurance and do scaffolders need it?
Contract works (also called erected scaffold insurance or material damage) covers the scaffold structure itself while it is erected on site. If the scaffold is damaged by storm, vandalism, fire, or vehicle impact, the cost of making it safe and re-erecting the damaged sections falls on the contractor without this cover. For long-duration scaffolds with high erected values, contract works cover is an important part of the package.
Is there a difference between scaffolding insurance and general contractors insurance?
Yes. General contractor insurance typically provides PL and EL cover for construction activities but may exclude or significantly limit cover for scaffolding operations specifically, or require a specialist scaffolding endorsement. Scaffolding-specific package policies are underwritten by insurers with appetite for the scaffolding sector and include contract works and scaffold-specific extensions not found in a generic contractor policy.
