Public Liability Insurance for Carpenters and Joiners

Public liability insurance for carpenters and joiners is meant to pay claims if your work injures someone or damages property that is not yours, from a dropped worktop cracking a tiled floor to a staircase you fitted failing after handover. Clients and main contractors may ask to see it before you start. If you make items in a workshop, employ staff or design structural timber, you may also need product liability, employers’ liability or professional indemnity cover.

What can go wrong in carpentry and joinery work?

Carpenters and joiners work with heavy materials, sharp tools and finished surfaces in clients’ homes and on building sites. Common sources of claims include:

• dropping a worktop, door or sheet material onto a floor, a bath or a client’s furniture;
• a circular saw or router damaging a finished surface, or cutting into a hidden cable or pipe;
• offcuts, cables or timber stacked in a corridor or on a pavement causing someone to trip;
• a staircase, balustrade, loft hatch or wall cabinet failing after the job is finished;
• a fire starting in a workshop with dust and timber stored together;
• disturbing hazardous material in an older building. HSE says asbestos may be part of any commercial or domestic building built or refurbished before 2000.

Example. A joiner makes and fits a new oak staircase with a glass balustrade in a family home. Four months later a visitor leans on the handrail, a fixing pulls out of the newel post and the visitor falls and breaks a wrist. The visitor claims against the homeowner, who passes the claim to the joiner. Because the injury happened after the job was handed over and involves something the joiner made, the claim may fall under public liability, product liability or both. How it is handled depends on the policy wording, which is why joiners who make as well as fit should check both covers are in place.

Which covers fit a carpentry or joinery business?

Cover	What it is for	When to consider it
Public liability	Injury to third parties or damage to their property caused by your work, subject to the policy wording	For any carpenter or joiner working in other people’s homes, premises or sites
Product liability	Injury or damage caused by items you make or supply	If you make doors, windows, stairs, kitchens or furniture in a workshop
Employers’ liability	Claims from employees for injury or disease caused by their work	As soon as you employ someone. GOV.UK says cover must be for at least £5 million from an authorised insurer
Tools and equipment	Theft of or damage to saws, routers, nail guns and hand tools	If replacing your tools would stop you working
Contract works	Damage to work in progress before handover	On first fix, second fix and timber frame work, or where a contract asks for it
Professional indemnity	Claims that your design, drawings or specification were wrong	If you design staircases, roof structures or bespoke joinery that a client relies on

Our guide to what public liability insurance is covers the main policy, and our page on product liability insurance explains the cover for items you make. If you design as well as build, read what professional indemnity insurance is.

Do I need employers’ liability insurance for apprentices or labourers?

GOV.UK says you must get employers’ liability insurance as soon as you become an employer, from an authorised insurer, with cover of at least £5 million. You can be fined £2,500 for every day you are not properly insured, and £1,000 if you do not display your certificate where employees can access it. The only exemptions GOV.UK lists are employing a close family member or someone based outside England, Scotland and Wales.

Joiners often work with labourers or other trades on a day rate. GOV.UK notes that the rules differ for agency staff, freelancers and contractors, so tell us how each person is engaged. Our page on employers’ liability requirements has more detail.

What may clients and main contractors ask for?

• Homeowners may ask to see your public liability certificate before a kitchen fit or staircase job.
• Main contractors may ask for public liability and employers’ liability at stated limits, evidence of competence, and method statements for site work.
• Developers and commercial clients may ask whether you hold product liability if you supply made items, and contract works cover for first fix or frame work.
• Architects and designers may ask about professional indemnity if you are taking on design responsibility.

On domestic jobs, HSE says that where there is a single contractor, the contractor must take on the legal duties of the client under the Construction (Design and Management) Regulations 2015, as well as their own. If you work on larger sites, our page on public liability for builders covers the wider construction risks.

Which health and safety risks affect cover for joiners?

• Wood dust. HSE says carpenters and joiners are four times more likely to get asthma than other UK workers, and that hardwood dust can cause cancer, particularly of the nose. The workplace exposure limit is 3mg/m3 for hardwood dust and 5mg/m3 for softwood dust, with the hardwood limit applying to mixtures.
• Dust control on site. HSE recommends H or M class on tool extraction for cutting and sanding, and says respiratory protection with an assigned protection factor of at least 20, such as FFP3, will be required for most cutting and sanding.
• Work at height. HSE says working at height remains one of the biggest causes of fatalities and major injuries, with falls from ladders among common cases.

These points are mainly about your employees and your own health, which is where employers’ liability comes in. A workshop also raises fire and machinery questions, so expect an insurer to ask about dust extraction, waste removal and how timber is stored.

What drives the price of cover for a carpenter or joiner?

We do not give typical figures. The price reflects your own business, and the main factors are:

• the split between site work, domestic fitting and workshop manufacture;
• whether you make and supply items as well as fit them;
• any structural or design work;
• your turnover, and your wageroll if you have staff;
• the heights you work at and the use of scaffolding;
• the limit of indemnity your contracts require and the excess you choose;
• your claims history.

What should I have ready when asking for a quote?

1. Your trading name, business structure and years of experience.
2. A description of your work, split between fitting, site carpentry and workshop manufacture.
3. Your expected turnover for the next 12 months and any wageroll.
4. Who works with you and whether they are employees or subcontractors.
5. Whether you design, draw or specify anything for clients.
6. Workshop details, if you have one, including extraction and security.
7. The limits of indemnity your clients or contractors ask for.
8. Any past claims or incidents.

Before a contract of insurance is entered into, the law requires the insured to make a fair presentation of the risk to the insurer, so include the less common jobs too. When you are ready, ask us for a quote or call 01795 841 310, Monday to Friday 9am to 5pm, and we will look for cover. If you also take on general repairs, see our page on public liability for handymen.

Frequently asked questions

Do I need product liability as well as public liability?

If you make or supply items such as doors, windows, stairs or furniture, product liability is worth discussing. Whether a policy includes both depends on what you buy, so check your schedule or ask us to confirm.

Does public liability cover damage to a kitchen I am fitting?

It depends on the policy wording. Damage to the work you are carrying out can be treated differently from damage to the rest of the client’s property, and contract works cover may be the relevant policy during the job.

When would a joiner need professional indemnity insurance?

When a client relies on your design or advice, for example if you design a staircase, a roof structure or a bespoke piece of joinery. If you only build to someone else’s drawings, it is less likely to be needed.

Will an insurer ask about wood dust?

If you have employees or a workshop, expect questions about dust extraction and protective equipment. Following HSE guidance on wood dust, and keeping a record of how you control it, puts you in a better position when you answer those questions.
