Scaffolding contractors' insurance is the set of policies a firm that erects, alters, inspects and strikes scaffolding needs, so that a claim from a member of the public, a worker, another trade or a client doesn't land on the business's balance sheet. It's a specialist risk. Scaffolders work at height every day, put structures on public pavements, tie into buildings they don't own, and leave those structures for other trades to use long after the gang has left. Insurers price all of that, and most standard "tradesman" wordings either exclude scaffolding or load it heavily.
This guide is for scaffolding contractors in the UK: sole-trader scaffolders, small firms with one or two gangs, and established companies with yards, lorries, designers and inspectors. It follows the life of a scaffold, from tender to strike, and shows which policy responds at each stage and what the law and your clients expect. If your question is about moving scaffold kit by lorry (goods in transit, loading and unloading, the vehicles themselves), that's a different job, covered in our guide to scaffolding haulage insurance. For trades in general, start with contractor insurance.
The short answer: what a scaffolding contractor usually buys
Cover | What it pays for | Why scaffolders need it |
|---|---|---|
Public liability | Injury to third parties and damage to their property caused by your work | A fitting dropped onto a pedestrian, a collapse onto a neighbour's roof, a tie that cracks a façade. Councils and main contractors ask for proof and set minimum limits. |
Employers' liability | Claims from your employees injured or made ill at work | A legal requirement once you employ people, with a minimum of £5 million. Falls from height and manual handling make it a core cover for scaffolders. |
Own plant and scaffold stock | Loss of or damage to tube, fittings, boards, system components, beams and ladders you own, on site, in the yard and in transit if extended | Stock is often the biggest asset a scaffolding firm owns, and it sits on open sites for weeks. |
Hired-in plant | Your liability for equipment you hire in, plus continuing hire charges in some wordings | Hire contracts usually make you responsible for hired kit until it's returned. |
Contract works (contractors' all risks) | Damage to the works you're building or responsible for under the contract | Needed when your contract makes you responsible for the works, such as a temporary roof or a structure you're building, not just access. |
Professional indemnity | Financial loss from negligent design, calculation, specification or advice | Relevant if you design bespoke scaffolds, issue calculations, or sign off designs for others. |
Tools | Theft or damage to hand tools, spanners, levels, tie testers | Often a section of the own plant cover; check the van theft conditions. |
Some firms add personal accident cover for directors and sole traders, and business interruption for the yard. Lorries, goods in transit and loading are the transport side, covered in the haulage guide linked above.
Stage 1: tendering and signing the contract
Most scaffolding insurance problems start before the first tube goes up, when the contract is signed without anyone checking the insurance clauses against the policy.
Limits the client asks for
Main contractors, housebuilders, facilities managers and public bodies usually set a minimum public liability limit in their subcontract or framework. Highway authorities set their own limit as a condition of a scaffold licence (more on that below). If your policy limit is lower than the contract asks for, you can be in breach of contract even if no claim ever happens, and you may be removed from approved supplier lists.
Indemnity clauses
Many subcontracts ask the scaffolder to indemnify the main contractor or client against claims arising from the scaffold. A public liability policy covers your legal liability for injury and damage. It doesn't automatically cover every promise you make in a contract. Look for:
Indemnity to principals. Wording that extends cover to the client or main contractor for claims arising from your work. Many contracts require it.
Contractual liability. Some liability you take on by contract that wouldn't exist at law is excluded unless the policy says otherwise. Send the clause to your broker before you sign, not after the claim.
Waiver of subrogation. Some contracts ask your insurer to give up its right to recover from the client. Not every policy allows it.
What the contract says about the scaffold itself
Check who is responsible for loss of or damage to the scaffold while it's on site. On most jobs it stays your property and your risk. That's what own plant cover is for. If the client takes responsibility, get that in writing. If the contract asks you to insure "the works", ask whether that means the scaffold, the building, or both.
CDM 2015 duties you're signing up to
Under the Construction (Design and Management) Regulations 2015, every contractor must plan, manage and monitor its own work so that, so far as is reasonably practicable, it's carried out without risks to health and safety. On projects with more than one contractor, you must follow the principal designer's and principal contractor's directions and the relevant parts of the construction phase plan. You mustn't employ or appoint anyone on site unless they have, or are getting, the skills, knowledge, training and experience for the work. You also mustn't start work on site unless reasonable steps have been taken to prevent unauthorised access. And if you're the only contractor on a project, you must draw up a construction phase plan before setting up the site. Insurers read your answers about CDM as evidence of how you manage risk, not as box-ticking.
Stage 2: design, before anything is erected
When a scaffold needs a design
The Work at Height Regulations 2005 say strength and stability calculations for scaffolding must be carried out unless a note of the calculations covering the structural arrangements is available, or the scaffold is assembled in conformity with a generally recognised standard configuration. HSE gives the National Access and Scaffolding Confederation's TG20 guidance for tube and fitting scaffolds, and manufacturers' instructions for system scaffolds, as examples of a generally recognised standard configuration.
Depending on the complexity of the scaffold, an assembly, use and dismantling plan must be drawn up by a competent person. It can be a standard plan supplemented with details specific to the scaffold, and a copy must be kept available for anyone involved in its assembly, use, dismantling or alteration until it's taken down.
HSE lists structures that normally need a bespoke design. They include shoring scaffolds, truss-out scaffolds, façade retention, temporary roofs and temporary buildings, pavement gantries, towers that need guys or ground anchors, slung and suspended scaffolds, and system scaffolds outside the manufacturer's guidance. HSE also says that any alteration that takes a scaffold outside a standard configuration must be designed by a competent person and proven by calculation.
Why design matters to your insurance
This is where professional indemnity comes in. Public liability is built for physical injury and property damage. When the problem is a design error, especially one that costs the client money without anyone being hurt, a liability policy may not respond. Examples include a design that has to be re-done, a programme delay because a scaffold has to be re-designed, or a temporary roof that has to come down and go back up. Liability wordings often exclude loss arising from design or advice given for a fee.
Ask yourself three questions:
Do we design in-house? If you employ or contract a scaffold designer, or produce calculations, you need to tell your insurer and consider professional indemnity. See our professional indemnity guide.
Do we use an outside designer? Check that the designer carries professional indemnity and that your contract with them lets you recover if their design is wrong.
Do we only erect to TG20 compliance sheets or manufacturers' configurations? You may still give advice about loading, ties or sheeting. Tell your insurer what you do so the wording matches.
Information that keeps the design right
HSE says the user should brief the scaffold contractor at the start (period and intended use, dimensions, boarded lifts, loads, access, sheeting, ground conditions and the building tied into), and the contractor or designer should state the load class, bay lengths, lift heights, tie spacing and duty, and leg loads. Keep this exchange in writing. If the client changes the brief and the scaffold fails, that paper trail is often what decides who pays.
HSE also warns that sheeting or debris netting should never be attached to a scaffold without telling the people who designed and erected it, because the scaffold must be designed for it. Sheeting changes wind loading. If a client's trade adds sheeting without telling you, record it and tell the client in writing.
Stage 3: putting scaffolding on the public highway
The licence
In England and Wales, section 169 of the Highways Act 1980 says that no one may erect or retain scaffolding or another structure that obstructs a highway, in connection with building or demolition work or the alteration, repair, maintenance or cleaning of a building, without a written licence from the highway authority. The authority can attach whatever terms it thinks fit.
Once licensed, you have three statutory duties under section 169(4). You must make sure the structure is adequately lit between half an hour after sunset and half an hour before sunrise. You must follow the authority's written directions about traffic signs. And you must do what statutory undertakers reasonably ask to protect or give access to their apparatus. The lighting and signs duties don't apply where no part of the structure is less than 18 inches horizontally from the carriageway and no part over the footway is less than 8 feet above it. Breaching the licence requirement or these duties without reasonable excuse is an offence, with a fine up to level 5 on the standard scale.
Section 169(7) gives some protection: no civil or criminal proceedings lie for an obstruction caused by a licensed structure if the licensee carries out its section 169(4) duties. That's protection for obstruction only. It doesn't stop a claim from a pedestrian hit by a falling fitting, and it won't help if you've let the licence lapse or ignored its terms.
In Scotland and Northern Ireland, permissions for structures on roads come under different legislation. Check with the local roads authority before you erect.
The public liability limit councils ask for
Highway authorities set their own insurance conditions, and the figure varies. In October 2026 we checked several council websites. Oxfordshire, Luton, Buckinghamshire and Manchester all asked for evidence of £10 million public liability. Warwickshire asked for £10 million public liability from both the scaffolder and the applicant, plus £10 million employers' liability where operatives are directly employed, and said it may ask for more on sites that need a higher level of cover. Some councils also ask for evidence of competence. Buckinghamshire asked for a scaffolding qualification and New Roads and Street Works Act accreditation; Luton asked for the scaffolder's accreditation.
What this means in practice:
Check the limit before you apply. If you work across several councils, a £5 million limit may stop you getting licences.
Your employers' liability limit may need to be higher too. The legal minimum is £5 million, but some councils and main contractors ask for more.
Keep the certificate current for the whole licence period. Councils often want a certificate that covers every day the scaffold is up. Check your renewal date against the licence end date.
Name the right entity. The licence, the certificate and the company erecting the scaffold should match. Councils often issue the licence to the scaffolding company, not the builder.
Pavement risks insurers ask about
Street scaffolds bring pedestrians under live lifts, vehicle strikes on standards and children climbing at night. Insurers will ask whether you use pavement gantries, fans and brick guards; how you light and sign the structure; and how you stop access out of hours. Under the Work at Height Regulations, a scaffold that isn't available for use, including during assembly, dismantling or alteration, must carry warning signs and be physically fenced off from the danger zone. HSE has issued a safety alert on preventing unauthorised access to scaffolding, and many claims come from people who should never have been on the scaffold.
Stage 4: erecting, altering and dismantling
Competence and supervision
The Work at Height Regulations say scaffolding may be assembled, dismantled or significantly altered only under the supervision of a competent person, and by people with appropriate and specific training. That training covers understanding the plan, safety during the work, preventing people and materials from falling, weather changes, permissible loads, and any other risks.
HSE refers scaffolders to the National Access and Scaffolding Confederation's guidance SG4, Preventing falls in scaffolding operations, or to manufacturers' guidance for system scaffolds. The priority is collective fall protection, so operatives spend as little time as possible relying on harnesses. HSE also links to the Construction Industry Scaffolders Record Scheme (CISRS), the industry's card and training scheme for scaffolders.
Insurers typically ask:
what proportion of operatives hold CISRS cards, and at what level;
whether you follow SG4 or a manufacturer's safe system;
whether you're a member of a trade body or accreditation scheme (NASC membership is one example many main contractors look for);
how you supervise trainees and labourers.
Trade body membership isn't a legal requirement, but it and good training records help show an underwriter you manage the risk.
Your people: employees, labour-only and self-employed
Employers' liability is compulsory once you employ people. It must be from an authorised insurer, for at least £5 million for any one occurrence. The certificate must be displayed where employees can easily see it; GOV.UK says that can include online, such as on your website or intranet. GOV.UK also says you can be fined £2,500 for every day you're not properly insured, and £1,000 if you don't display the certificate or show it to an inspector when asked. See our guide to employers' liability insurance.
Scaffolding firms often use labour-only subcontractors who work under your direction, with your kit and on your jobs. For insurance purposes they're usually treated as employees, whatever their tax status. Tell your insurer how many there are. If you use bona fide subcontractors (separate firms with their own insurance and their own kit), get copies of their public and employers' liability certificates and check the limits before they start. If they're uninsured, a claim against them can end up as a claim against you.
If you're a sole trader working alone, employers' liability isn't usually required by law, but a main contractor may still ask for it. And the moment you take someone on, even for one job, you need it.
Stage 5: while the scaffold stands
This is where scaffolders are most exposed: the gang has left and other trades are using the scaffold.
Inspections and handover
Under regulation 12 of the Work at Height Regulations, every employer must ensure that a working platform used for construction work, from which a person could fall 2 metres or more, isn't used unless it's been inspected in that position within the previous 7 days. Equipment whose safety depends on how it's assembled must be inspected after assembly in that position before use. And it must be inspected again whenever exceptional circumstances could affect its safety.
The person inspecting a platform covered by the 7-day rule must prepare a report before the end of the working period. That report must be given to the person the inspection was done for within 24 hours. Schedule 7 says what it must include: who it was for, the location, a description of the equipment, the date and time, any risks found, actions taken, further action needed, and the inspector's name and position. The report must be kept on site until the construction work is completed, and then at an office for 3 months.
HSE says the scaffold user or hirer is responsible for making sure the scaffold is inspected. Inspectors must be competent, and HSE says competence may have been assessed under CISRS. Tag systems aren't a legal requirement, but HSE describes them as a useful supplement to inspection reports.
The insurance point is simple. If you're contracted to inspect, the inspection is part of your work and your liability. Your insurer needs to know you do it. If you aren't contracted to inspect, your handover documents need to say so clearly. Insurers ask whether you issue handover certificates, whether you inspect for clients, and how long you keep the records.
Regulation 12(5) also matters if you hire scaffolding to others or take it from another firm: equipment leaving one business, or used after it comes from another, must be accompanied by physical evidence that the last inspection was carried out.
Other trades and unauthorised alterations
Ties removed by a window fitter, boards lifted by a roofer, a loading bay overloaded with blocks: these are common causes of scaffold failures. If the collapse injures someone, the claimant may sue everyone: you, the main contractor and the trade that made the change. Clear handover terms, a "no unauthorised alterations" notice, signed inspection records and photos at handover help your insurer show the scaffold was safe when you left it.
HSE describes load classes: general-purpose scaffolds should be assumed to carry a maximum of 2 kN/m² unless the provider says otherwise. "Very light duty" is 0.75 kN/m² and "heavy duty" is 3.0 kN/m². Write the load class on the handover certificate. It's the best evidence you have if a trade later overloads the scaffold.
Weather, theft and vandalism
High winds can bring down sheeted scaffolds, and storms can trigger the "exceptional circumstances" inspection duty. Your own plant cover should pay for damaged stock, but check:
Theft conditions. Some policies only cover theft from sites with secure compounds, or from locked vans with visible signs of forced entry.
Unattended sites. Ask whether cover applies when the scaffold stands on an empty site for weeks.
Stock counts. Insurers want to know how you track tube and fittings. Unexplained shortages found at strike usually aren't covered.
Stage 6: the yard, the stock and the kit you hire
Your own scaffold stock
Tube, fittings, boards, system components, beams and ladders can be worth a lot, and they're spread across many sites. Own plant cover (sometimes called contractors' equipment) insures them against loss or damage. Ask your broker to confirm:
the sum insured is based on replacement cost at today's prices, not what you paid years ago;
cover applies on site, in the yard and, if needed, in transit;
the limit per site is high enough for your biggest job;
the policy covers kit you've hired out to others, if you do that.
If you hire scaffolding to other firms or to the public, tell your insurer. Hiring out is a different risk from erecting, and some policies exclude it unless agreed.
Hired-in plant
When you hire in system scaffold, hoists, beams or towers, the hire contract usually makes you responsible for the kit until it goes back, and sometimes for hire charges while damaged kit is repaired. A hired-in plant extension or policy covers that liability. Check the limit against your biggest hire and whether continuing hire charges are included.
The yard
If you own or lease a yard, consider property cover for buildings and contents and business interruption if a fire or flood stops you loading out. Insurers will ask about fencing, lighting, CCTV and alarms.
Six claims, and which policy responds
A coupler falls from the fourth lift and hits a pedestrian. Public liability. The council licence terms, the fans and brick guards, and your inspection records all feed into the defence.
A labourer falls from an incomplete lift during erection. Employers' liability. Insurers will look at SG4 compliance, supervision and training records.
A scaffold collapses after a roofer removes ties without permission. Public liability may respond to claims against you, but your handover certificate, inspection reports and "do not alter" signage are what show where liability lies.
Your designer's calculation for a temporary roof is wrong. It has to be taken down and re-erected, delaying the main contractor by three weeks. Professional indemnity, if you have it. A public liability policy may not respond to pure financial loss from a design error.
Thieves take a load of fittings and boards from an unattended site over a weekend. Own plant cover, subject to the theft and security conditions.
Hired-in system scaffold is damaged in a storm. Hired-in plant cover, plus continuing hire charges if the wording includes them.
Ten questions an insurer will ask a scaffolding contractor
What do you erect: domestic, commercial, industrial, heritage, events, or a mix?
What's the maximum height you work at, and do you work over roads, railways or water?
Tube and fitting, system scaffold, or both?
Do you design scaffolds, and who does the design?
Do you erect only to TG20 compliance sheets or manufacturers' configurations?
How many employees, labour-only and bona fide subcontractors do you use?
What CISRS card levels do your operatives hold?
Do you inspect scaffolds for clients, and how do you hand over?
What's your stock worth, where is it kept, and do you hire it out?
What's your claims history for the last five years, including incidents that haven't become claims yet?
Under the Insurance Act 2015 you must make a fair presentation of the risk, disclosing every material circumstance you know or ought to know, or at least enough to put the insurer on notice that it needs to ask more. Answer the questions above in full, and don't understate the height or the design work you do.
What changes the price
We don't publish "from £X a month" prices for scaffolding insurance, because the premium follows the work you do. The factors that usually move it are:
Height and location. Working on high-rise, over public highways, next to railways or over water.
Design work. Bespoke designs and temporary works need professional indemnity and more underwriting.
Headcount and labour mix. Payroll, numbers of labour-only operatives and use of subcontractors.
Training and accreditation. CISRS cards, SG4 compliance and trade body membership.
Limits. Higher limits cost more, but may be needed for licences and contracts.
Claims history. Especially falls from height and dropped objects.
Stock value and security. The value of your kit and how you protect it.
There are fewer insurers for scaffolding than for most trades. That's why it helps to present the risk well. Ways to keep the price down are covered in our guide to reducing commercial insurance costs.
How scaffolding fits with the other trades on site
On a typical job the scaffolder is one of several trades, each with its own cover. Electricians and plumbers working from your scaffold carry their own public liability for their own work: see electrician insurance and plumbing and heating engineer insurance. The main contractor usually arranges contract works cover for the building. The scaffolder's policy covers the scaffold and the scaffolder's work. Where those overlap, contracts and handover documents decide who pays. Our general guides to public liability insurance and contractor insurance explain the basics for every trade.

Frequently asked questions
Is scaffolding insurance a legal requirement?
Employers' liability is compulsory once you employ people, with a minimum of £5 million. Public liability isn't required by law, but highway authorities require it as a condition of a scaffold licence, and main contractors require it in subcontracts. In practice, a scaffolding contractor can't trade on most sites without it.
How much public liability does a scaffolder need?
It depends on your contracts and the councils you work in. Several councils we checked in October 2026 asked for £10 million for a scaffold licence. Some main contractors ask for more. Check the highest limit any of your clients or councils require and buy at least that.
Do I need professional indemnity as a scaffolder?
If you design scaffolds, produce calculations, or advise clients on scaffold design, yes, you should consider it. If you only erect to TG20 compliance sheets or manufacturers' configurations, you may not, but tell your broker what advice you give so they can check the wording.
Does my insurance cover scaffolding that other trades have altered?
Your public liability may respond to a claim against you, but the key question is liability. Clear handover certificates, signed inspection reports and "no unauthorised alterations" signs help show that the scaffold was safe when you handed it over.
Do I need a licence to put scaffolding on a pavement?
In England and Wales, yes. Section 169 of the Highways Act 1980 requires a written licence from the highway authority for scaffolding that obstructs a highway. Apply to the council for the area. Each council sets its own terms, fees and insurance requirements.
Is my scaffold stock covered by my public liability policy?
No. Public liability covers your liability to others. Your own tube, fittings and boards need own plant (contractors' equipment) cover. Hired-in kit needs hired-in plant cover.
I'm a sole trader scaffolder with no employees. What do I need?
Public liability at the limit your clients and councils ask for, cover for your own kit and tools, and possibly personal accident cover. Employers' liability isn't usually required by law if you work alone, but you'll need it as soon as you take anyone on, even a labourer for a day.
Can you cover scaffolding firms?
Sometimes. Scaffolding is a specialist risk, and fewer of the insurers on our panel write it than write general trades. Tell us what you do and we'll say honestly whether we can place it.
