Scaffolding public liability insurance is the cover that a scaffolder, or a firm that puts up scaffolds for others, is often asked to show before work starts in the UK. This guide sets out what councils, the trade body and the Health and Safety Executive (HSE) say, why height limits and licence dates matter, and where employers' liability fits. We checked the pages on 4 November 2026. We explain and do not recommend a policy.
Quick answer
We found no law that requires scaffolding public liability insurance, but highway licences and the trade body set minimums, from £5 million to £10 million in the examples we read. Employers' liability is a separate cover.
Scaffolding Public Liability Insurance at a Glance
| Question | Short answer |
|---|---|
| Is it compulsory by law? | We found no statute that says so |
| When does a licence come in? | HSE says a scaffold that encroaches on the highway needs a licence under section 169 of the Highways Act 1980 |
| What do councils ask for? | £5 million to £10 million in the five examples below |
| What does the trade body ask of members? | Employers' liability of £10 million and public liability of £5 million |
| Does it cover your own staff? | No, that is employers' liability |
| What can void cover? | A height limit in the wording, according to one trade article |
| Can we give a price? | No, no source we opened supports one |
What Scaffolding Public Liability Insurance Responds To
Public liability responds to claims by third parties for injury or damage that your work causes. For a scaffolder that means people and property outside the firm: a passer-by, a neighbour, a parked vehicle, the client's building. Our hub guide explains the cover in general terms, so we focus on what is particular to scaffolds.
HSE's page, updated on 19 May 2026, shows why the public side matters. It says erection and dismantling should not take place over people or busy pavements, that barriers and warning signs should keep people out of danger zones, and that guard rails and toe boards should stop objects falling. Picture a scaffolder dismantling a pavement scaffold when a board slips and damages a parked car. That is a third-party property question. The same fall injuring a labourer on the team is an employers' liability question.
| Event | Cover that usually responds | Check in the wording |
|---|---|---|
| A board lands on a passer-by | Public liability | Injury to the public |
| A pole damages a parked car | Public liability | Third-party property damage |
| A team member falls | Employers' liability | Who counts as an employee |
| The scaffold is stolen | Tools and equipment cover | Whether it is included |
Highway Licences and Scaffolding Public Liability Insurance
A scaffold on a pavement needs permission from the highway authority, and the licence often carries an insurance condition. The table sets out five councils we read. Each is one council's wording, not a national rule, and several pages are old.
| Council | Public liability asked | Other points | Page date |
|---|---|---|---|
| Hampshire | £10 million | Employers' liability of £10 million where operatives are employed | Undated |
| Swindon | At least £10 million | Certificate uploaded with the application | Metadata of 23 November 2015 |
| Lincolnshire | At least £10 million | Certificate must cover the dates requested | Metadata of 30 April 2020 |
| Southwark | £10 million for emergency scaffolding | No amount stated for standard licences | 20 April 2021 |
| Medway | At least £5 million | Public liability, not employers' liability | 10 December 2019 |
Four of the five say £10 million, and Medway says £5 million, so on our arithmetic the higher figure is twice the lower. Treat the 2015, 2019, 2020 and 2021 pages as old, and confirm the live requirement with the council. Our construction guide owns the wider comparison of contract limits. The so what: read the licence for your highway authority before you ask for a quote, because the figure changes by council.
Licence Dates, Extensions and Who Applies
The dates on the licence and the dates on the certificate need to line up. Lincolnshire says a scaffold licence runs for up to 28 days, with two extensions permitted up to 28 days each, and that the certificate must cover the dates requested. On our reading, a policy that ends before an extended period would leave the extension uncovered, though we cannot say how an insurer or council would treat that case.
Hampshire says the licence cannot be transferred to another firm, and that erection cannot start before the date on the licence. It also says the licensee must indemnify the highway authority against related liability. Lincolnshire says a suitably qualified provider, not a resident, must apply. The step is to tell your seller the licence period and any likely extension at the outset.
The Trade Body Baseline
The National Access and Scaffolding Confederation (NASC) is the trade body that the charter comes from. Its membership charter, issued in October 2024, says member businesses must hold employee liability and public liability insurance to £10 million and £5 million. It does not say whether the limits are per claim or in the aggregate. The charter uses the words "Employee Liability", and we assume it means employers' liability.
Lincolnshire says it may ask for a regulated scaffolding association membership certificate. The comparison is the useful part. Four councils ask for £10 million of public liability, while the trade body asks members for £5 million, so on our arithmetic membership alone would sit at half the council figure. Membership is a separate requirement, and a council can ask for more. Check both documents.
Employers' Liability and Subcontractors
Scaffolding teams often include labour-only workers, which makes the employers' liability question harder. Gov.uk says most employers need at least £5 million of employers' liability, and Hampshire's licence asks for £10 million where operatives are directly employed.
Two commercial sources differ on subcontractors. A trade article published on 7 December 2020 says employers' liability does not apply to bona fide subcontractors. A broker page with no date says its employers' liability covers labour-only subcontractors. We cannot reconcile them, and neither defines the status test. The step is to ask your insurer in writing how it treats each person on your gangs.
Height Limits and Other Conditions in the Wording
Height is the condition most specific to scaffolding. The trade article calls height restrictions the most obvious restriction for scaffolders, and warns that working above a restricted height could void cover. A Partners& page, last modified on 23 September 2025, tells readers to check for a height limit and for restrictions on where they work. The broker page above says various height limit options exist, including unlimited.
| Source | What it says about height | Date |
|---|---|---|
| Trade article | Working above a restricted height could void cover | 7 December 2020, old |
| Partners& | Check for a height limit and location limits | 23 September 2025 |
| Broker page | Various height limit options, including unlimited | Undated |
The Partners& page also says fewer insurers now offer this cover, so renewal problems or price rises are possible. That is a commercial claim, and we cannot test it. The takeaway: compare the height limit in the schedule with the tallest scaffold you expect to build in the policy year.
Safety Duties That Sit Beside the Policy
Insurance does not replace the safety rules. HSE says scaffolds must be designed, erected, altered and dismantled only by competent people under a competent supervisor, a requirement of the Work at Height Regulations 2005, on a page dated 26 February 2026. It says the law requires inspection of scaffolding from which a person might fall 2 metres or more, with a report on completion and at least weekly after that.
HSE's other page adds that users must ensure inspections happen before first use and after events such as high winds, and that a plan for assembly, use and dismantling must be kept until the scaffold is down. A tag system is not a legal requirement. We found no source that says an insurer makes inspections a condition of cover, so that is a question for your seller. Our requirements guide covers the contracts that ask for cover.
Questions to Ask Before You Buy
Say a small scaffolding firm wins a job on a high street frontage. The council wants a licence with its own insurance figure, the firm's trade body charter sets a lower public liability figure for members, and the client's contract adds a third. The firm holds one policy, so the question is which of the three documents asks for the most, and whether the schedule meets that one. We cannot say what any particular insurer would accept, and we do not advise on limits.
The sensible order is to collect the three documents first, note the highest figure and the dates, and only then ask for quotes. A quote requested before that step can come back with a limit or a height cap that fails one of the documents, and the gap is easier to spot on paper than at the licence desk. The list below is ours and does not tell you what to buy.
- Which licence or contract sets the limit, and is it per claim or in the aggregate?
- Does the certificate cover every licence date, including any extension?
- What height limit does the schedule state?
- How does the policy treat labour-only and bona fide subcontractors?
- Does the schedule cover tools and equipment, or is that separate?
Our cost guide covers what moves a premium. The Insurance Act 2015 duty of fair presentation applies to business contracts, and Part 2 of the Act, as enacted, asks you to disclose what you know or ought to know, so describe your heights and your gangs accurately.
Checking the Seller and Making a Complaint
Check the seller on the FCA Financial Services Register, last updated on 13 February 2026. If you need to complain, contact the firm first. You can then go to the Financial Ombudsman Service within 6 months of the final response, subject to its size tests.

Frequently Asked Questions
What is scaffolding public liability insurance? It is public liability cover for claims by third parties for injury or property damage caused by scaffolding work. A trade article lists it among the covers for scaffolders, alongside employers' liability. Your wording decides what it pays.
Is scaffolding public liability insurance a legal requirement? We found no statute that requires it. HSE says a scaffold on the highway needs a licence, and councils attach insurance conditions to those licences. Employers' liability is compulsory for most employers.
How much cover do councils ask for? In the five examples we read, four asked for £10 million and one for £5 million. Hampshire asks for £10 million. Several pages are old, so confirm with the council that issues your licence.
What does the trade body ask of members? The NASC charter, issued in October 2024, says member businesses must hold employers' liability of £10 million and public liability of £5 million. A council licence may ask for more.
Does a height limit matter? Yes, according to one trade article, which says working above a restricted height could void cover. Check the height limit in your schedule against your tallest jobs, and ask for the answer in writing.
Does it cover my labourers? Not public liability, which responds to third-party claims. Employers' liability is the relevant cover, and gov.uk says most employers need at least £5 million. Sources differ on subcontractors, so ask your insurer.
Do I need the certificate to match the licence dates? Lincolnshire says the certificate must cover the dates requested. Check the wording on your own licence, and tell your seller about any extension.
