Plasterer Insurance (Site Work, Materials): A UK Guide to Construction Insurance

Plastering is one of those trades that looks straightforward from the outside—until you’re the one carrying boards up stairs, mixing materials on a busy site, and trying to finish a perfect surface while other trades work around you. Whether you’re a sole trader doing domestic skimming jobs or a subcontractor on commercial builds, the risks are real: accidental damage, injury claims, tool theft, and disputes about workmanship can all hit hard.

That’s where plasterer insurance comes in. In the UK, most plasterers need a mix of construction insurance policies to protect themselves, meet contract requirements, and keep cashflow stable if something goes wrong.

This guide focuses on the realities of plastering—site work and materials—and explains the main types of cover plasterers typically need, what’s usually included/excluded, and how to choose the right setup.

Why plasterers need specialist construction insurance

Plasterers work in environments where small mistakes can become expensive problems.

Common plastering-related risks include:

• Damage to client property (e.g., splashed plaster on flooring, damaged skirting/frames, cracked tiles from dropped materials)

• Injury to third parties (e.g., a customer trips over your hop-up/extension lead; a visitor slips on dust)

• On-site hazards (scaffolding, stairwells, wet surfaces, manual handling injuries)

• Materials issues (stolen bags of plaster, damaged boards, contaminated materials, incorrect storage)

• Tool theft (from vans, site cabins, or properties)

• Allegations of poor workmanship (e.g., uneven finish, cracking, delamination, damp-related failures)

• Contract disputes (retentions withheld, snagging disagreements, delays caused by other trades)

The right insurance won’t stop issues happening—but it can stop one incident from wiping out months of profit.

The core policies for plasterer insurance

Most plasterers build their insurance around a few key covers. Your exact mix depends on whether you’re working domestic vs commercial, whether you use labour-only subcontractors, and what your contracts demand.

1) Public liability insurance (the non-negotiable for most plasterers)

Public liability insurance protects you if your work causes injury to a member of the public or damage to third-party property.

For plasterers, this is often the first policy clients ask about—especially builders, principal contractors, and letting agents.

Typical examples:

• You spill plaster slurry on a client’s hardwood floor and it stains

• A customer slips on dust or wet plaster near a doorway

• You accidentally damage a radiator pipe while prepping a wall

• A ladder knocks a window and it cracks

Common limits: £1m, £2m, £5m, or £10m. Many commercial sites require £5m as standard.

What to watch:

• Make sure the policy wording covers plastering, rendering, dry lining, skimming, and any related activities you do

• If you do external rendering or work at height, confirm it’s included

• If you use heat tools (e.g., drying equipment), check any heat work conditions

2) Employers’ liability insurance (legal requirement if you employ anyone)

If you employ staff—even part-time—or you have labour-only subcontractors who could be deemed employees, you may need employers’ liability insurance.

In the UK, it’s a legal requirement in most cases, and the usual minimum cover is £5m (many policies provide £10m).

It covers claims if an employee is injured or becomes ill due to work.

Examples:

• A mate strains their back lifting boards and claims you didn’t provide safe manual handling support

• A worker develops respiratory issues after repeated exposure to dust

• A subcontractor trips over poorly managed materials and gets injured

Tip: If you regularly use subcontractors, it’s worth getting clear advice on whether they’re “bona fide” subcontractors or labour-only—because that can change what you legally need.

3) Contractors’ all risks (CAR) / contract works insurance

This is one of the most overlooked covers for plasterers, but it’s highly relevant—especially on site work.

Contract works insurance (often part of Contractors’ All Risks) can cover:

• The plastering work you’ve completed but not yet handed over

• Materials you’re responsible for on site

• Sometimes, temporary works (depending on the policy)

Examples:

• You finish a full re-skim, and before sign-off a leak from another trade damages the work

• Fresh plaster is ruined by vandalism overnight

• Boards and bags of plaster stored on site are stolen

Important: Some policies only cover materials once they’re on site, and some only cover them while in transit if you add that extension.

4) Tools and plant insurance (and why “site” matters)

Plasterers rely on tools: mixers, drills, lasers, stilts, hop-ups, trowels, sanding systems, and sometimes spray equipment.

Tools insurance can cover theft, loss, or damage—often with options for:

• Cover in your van

• Cover at home

• Cover on site

• Cover in locked site cabins/containers

What to watch:

• Many claims fail because of security conditions (e.g., van must have deadlocks, tools must be out of sight, cabin must be locked to a certain standard)

• Check whether the policy covers hand tools and powered tools separately

• Confirm if hired-in equipment is covered (or add hired-in plant cover)

5) Van insurance and goods in transit (materials and tools on the move)

Standard van insurance often covers the vehicle—but not necessarily the tools and materials inside.

If you regularly transport:

• Bags of plaster

• Plasterboard

• Beads, scrim, adhesive

• Expensive tools

…you may benefit from goods in transit cover (for materials) and/or tools in transit cover.

This can be especially useful if you’re moving materials between suppliers, storage, and multiple sites.

6) Professional indemnity (for plasterers who design/specify or advise)

Many plasterers don’t need professional indemnity insurance—but some do.

If you provide advice or specification that a client relies on, PI can be relevant. Examples:

• You advise on a particular system for damp-prone walls

• You specify materials or build-ups for fire-rated or acoustic systems

• You provide written recommendations that later lead to a dispute

PI typically covers financial loss arising from negligence in professional advice, not physical injury or property damage (that’s public liability).

7) Personal accident and income protection (protecting your earnings)

If you’re self-employed, the biggest risk is often you.

A broken wrist, back injury, or serious illness can stop you working immediately. Personal accident cover can pay a weekly benefit if you’re unable to work due to an accident.

Some policies also offer:

• Hospitalisation benefit

• Fracture benefit

• Death benefit

It’s not the same as full income protection, but it can be a practical option for trades.

Site work: the plasterer’s risk profile (and how insurance responds)

Plastering on site is different from domestic work. There are more people, more moving parts, and more contractual pressure.

Working alongside other trades

On busy sites, you’re often working around electricians, plumbers, joiners, and decorators.

Risks include:

• Someone else damages your finished work

• You’re blamed for damage caused by another trade

• Delays push you into rushed work and snagging disputes

Insurance can help with certain losses, but it’s also about documentation:

• Take date-stamped photos before and after

• Get sign-off on prep work where possible

• Keep records of materials used and batch numbers (useful if there’s a defect allegation)

Working at height and access equipment

Plasterers frequently use:

• Hop-ups and podium steps

• Mobile towers

• Scaffolding (provided by others or hired)

If you’re working at height, insurers may ask:

• Maximum working height

• Whether you erect towers yourself

• Whether you use harnesses or edge protection

Be honest—if your declared work doesn’t match reality, claims can become messy.

Dust, respiratory exposure, and health claims

Plaster dust and sanding dust can cause long-term health issues. Employers’ liability is the main policy for employee illness claims, but even as a sole trader, it’s worth treating dust control seriously.

Practical risk controls that can also help with underwriting:

• Use dust extraction sanding systems

• Provide masks/respirators (fit-tested where required)

• Keep COSHH assessments for materials

• Follow HSE guidance on silica and dust exposure

Materials: what you should consider (and what insurers often ask)

Materials are a big part of plastering costs, and they’re surprisingly vulnerable.

1) Where are your materials stored?

Insurers may ask whether materials are stored:

• At your home

• In a lock-up

• In a van overnight

• On site (open or in a locked container)

The risk (and premium) changes based on storage.

2) Are materials “your responsibility” under the contract?

On many jobs, the main contractor supplies materials. On others, you supply and store them.

If you’re responsible for materials, consider:

• Contract works cover for materials on site

• Goods in transit for materials being transported

• Clear written terms about when materials become the client’s responsibility

3) What about damage to materials (not theft)?

Materials can be damaged by:

• Water ingress

• Incorrect storage (e.g., plaster absorbing moisture)

• Fire

• Vandalism

Some policies cover accidental damage; others focus mainly on theft/fire. Always check the wording.

What plasterer insurance usually doesn’t cover (common exclusions)

Insurance is powerful, but it’s not a blank cheque. Common exclusions and limitations can include:

• Defective workmanship (the cost to redo your own work is often excluded)

• Wear and tear or gradual deterioration

• Poor maintenance of tools/plant

• Theft from an unattended vehicle unless strict security conditions are met

• Damage to property being worked on (sometimes excluded unless you add an extension)

• Contractual liability beyond what you’d be liable for in law

• Asbestos and certain hazardous materials

• Heat work exclusions if you use blowtorches or hot works without permits

A good broker will help you align the policy with how you actually work.

How much does plasterer insurance cost in the UK?

Pricing varies a lot based on:

• Turnover

• Number of employees/labour-only subcontractors

• Claims history

• Type of work (domestic vs commercial)

• Height work and access methods

• Whether you do rendering/external work

• Tool values and storage security

As a rough guide, a sole trader plasterer with basic public liability could pay from a relatively low monthly amount, while a subcontractor working on larger sites with employers’ liability, contract works, and tool cover will pay more.

The key is not to buy the cheapest policy—it’s to buy the policy that will actually respond when you need it.

What information you’ll need for a plasterer insurance quote

To get accurate cover, be ready with:

• Your business structure (sole trader/limited company)

• Turnover estimate for the year

• Number of employees and subcontractors

• Typical job types (skimming, dry lining, rendering, patching, full refurb)

• Domestic vs commercial split

• Max working height and access equipment used

• Any hazardous work (e.g., work in high-risk premises)

• Tool value and storage details

• Claims history (if any)

Choosing the right cover: practical recommendations

If you want a sensible, “covers the real world” setup, here’s a common approach.

For a sole trader doing mainly domestic work

• Public liability (often £2m)

• Tools cover (including van and site, if needed)

• Personal accident (optional but smart)

For subcontractors on commercial sites

• Public liability (often £5m)

• Employers’ liability (if required)

• Contract works / contractors all risks

• Tools and plant (with site cover)

• Goods in transit (if you carry materials regularly)

For plastering firms with staff and bigger contracts

• Public liability (£5m–£10m)

• Employers’ liability

• Contractors all risks (including materials)

• Tools/plant + hired-in plant

• Professional indemnity (if advising/specifying)

• Commercial vehicle fleet (if multiple vans)

Simple risk management tips that also help your insurance

Insurers like well-run trades. These habits can reduce claims and sometimes help with premiums:

• Keep a written RAMS pack for site work (risk assessments and method statements)

• Take photos of pre-existing damage before you start

• Use dust extraction and appropriate PPE

• Store materials off the ground and away from water sources

• Don’t leave tools in the van overnight (or meet the policy’s security conditions)

• Confirm in writing who is responsible for materials on site

• Keep invoices and serial numbers for tools

FAQs: Plasterer insurance (UK)

Do plasterers legally need insurance?

Public liability isn’t legally required, but many clients and contractors will insist on it. Employers’ liability is usually a legal requirement if you employ staff.

Is plastering considered high risk for insurance?

It can be, especially if you work at height, do external rendering, or work on large commercial sites. The risk is manageable with the right cover and good site practices.

Does public liability cover my workmanship?

Public liability can cover injury or property damage caused by your work, but it usually won’t pay to redo your own defective workmanship. Some policies offer limited “damage to property being worked on” extensions—always check.

Are my materials covered if they’re stolen from site?

Only if you have the right cover (often contract works/CAR) and you meet the security conditions. Theft from open sites can be restricted.

Do I need insurance if I’m a subcontractor?

Yes—most main contractors will require proof of public liability, and sometimes employers’ liability and contract works cover depending on your responsibilities.

Does tools insurance cover theft from my van?

It can, but only if the van meets the policy’s security requirements (locks, alarms, where parked, tools out of sight). Always read the conditions.

Final thoughts

Plasterer insurance isn’t just a box-ticking exercise for site access—it’s a practical safety net for the real risks of the trade: working around others, handling messy materials, and delivering a finish clients expect to be perfect.

If you want to keep moving forward without worrying that one accident, theft, or claim could derail your business, the right construction insurance package is a smart investment.
