What Is Plasterer Insurance?
Plasterer insurance is a package of covers designed for self-employed plasterers, rendering contractors, and drylining businesses. The core covers are public liability (PL) and employers liability (EL) where employees are involved, with add-ons for tools, plant, and occasionally professional indemnity for specification or design input.
Plastering work involves water, heavy wet materials, dust, and work in close proximity to sensitive finishes. Spilled plaster water affecting floors and ceilings, dust contaminating occupied spaces, and accidental damage to adjacent tiles or joinery are among the most common PL claim scenarios in the trade.

Public Liability: Key Risks for Plasterers
Plastering work generates several common PL claim scenarios. Wet plaster and plaster water spilling or dripping onto floors, through ceilings, or onto newly decorated surfaces in adjacent rooms is one of the most frequent. Plaster dust settling on and damaging sensitive equipment, furnishings, or decorated surfaces in occupied properties is another. Accidental damage to floor finishes, skirting boards, door frames, and window reveals during preparation work also generates claims regularly.
Standard PL policies cover these third-party property damage scenarios. The cover applies to accidental events during the course of the work. Damage caused by the contractor deliberate or grossly negligent actions may be excluded, though the threshold for this exclusion is high in practice.
EL and Dust Exposure Claims
Plastering operatives face occupational health risks from silica dust (from sand and aggregate) and from airborne plaster particles during mixing and sanding. EL covers claims from employees who develop respiratory conditions or other occupational illnesses attributable to their work environment. COSHH assessments, appropriate PPE, and LEV (local exhaust ventilation) are required by law and also expected by EL insurers. A failure to implement required dust controls can affect claims settlements if the employer is found to have breached their COSHH duties.
How Much Does Plasterer Insurance Cost?
Annual indicative costs for 2026:
- Sole trader plasterer, domestic work, PL GBP 1 million: approximately GBP 100 to GBP 180
- Sole trader, commercial and domestic, PL GBP 2 million + tools: approximately GBP 180 to GBP 300
- Small limited company, 2-3 employees, PL GBP 5 million + EL: approximately GBP 500 to GBP 1,200
Plastering is generally considered a medium-risk trade for insurance purposes, below electricians and scaffolders in risk profile, which is reflected in the relatively modest premiums for standard domestic work.

Frequently Asked Questions
Do I need insurance to work as a plasterer?
You are not legally required to hold PL insurance to work as a self-employed plasterer, but most clients - from homeowners to main contractors and housing associations - will require proof of PL insurance before allowing work to commence. EL is legally compulsory if you have any employees or qualifying subcontractors.
Does plasterer insurance cover damage to a client floor from spilled plaster water?
Yes. Accidental damage to a client property caused by your plastering activities is covered under standard PL insurance. Spilled plaster water damaging a floor finish, drips penetrating a ceiling, or plaster contaminating a newly decorated surface would all be covered claims. The policy covers the repair or replacement cost for the damaged third-party property.
Does my insurance cover the cost of repairing cracked or failed plasterwork?
Standard PL does not cover the cost of rectifying your own defective workmanship - for example, plasterwork that cracks due to incorrect mix ratios or failure to key the background properly. A defective workmanship extension covers the cost of repairing or re-doing failed plasterwork. Check whether this extension is available under your policy.
What tools should I insure as a plasterer?
Key tools to insure include trowels and floats, mixing drills and paddles, angle grinders and disc cutters, mixing buckets and baths, and any specialist equipment such as spray plastering machines. Tool cover should reflect the replacement value of all tools carried in the van or stored at a yard. Minimum security conditions usually apply for overnight van storage.
Is there a difference in insurance requirements for drylining and wet plastering?
The risk profile is broadly similar but drylining work typically involves more cutting and fixing activity with power tools and less water risk. Both activities are covered under standard tradesman PL policies. If the business carries out both wet plaster and drylining, confirm that both are explicitly included in the policy description of activities covered.
