Which businesses need public liability insurance most?

Any business whose work brings it into physical contact with the public or their property: construction and trades, cleaning, hospitality, retail, beauty, fitness, events, and mobile services working in customers' homes.

Do online-only businesses need it?

The exposure is much lower if nobody visits you and you never attend a client site. Online businesses more often need professional indemnity, cyber and stock cover instead.

Do charities and clubs need public liability?

Yes, in practice. Venues, councils and grant funders routinely require evidence of cover before a group can use a hall, run an event or receive funding.

Do I need it if I only subcontract?

Almost certainly. Main contractors typically require every subcontractor on site to hold their own public liability cover at a stated limit, and will ask for the certificate before you start.

BUSINESS GUIDE

Who needs public liability insurance?

If your work puts you near other people or their property, someone will eventually ask for a certificate. Here are the business types that almost always carry it in the UK, and the ones where other cover matters more.

Last reviewed August 2026

Trades and construction

Builders, electricians, plumbers, roofers, plasterers, groundworkers, joiners and decorators are the clearest case. You work in other people's property, often alongside other trades, with tools that can cause real damage.

Site access is usually the deciding factor: main contractors will not let you through the gate without evidence of cover at the limit their contract specifies.

Businesses the public walk into

Shops, cafés, restaurants, takeaways, salons, barbers, gyms, studios and clinics all have members of the public on the premises. Slips, trips, hot drinks, falling stock and treatment reactions are the everyday claims.

Commercial leases commonly require public liability at a stated limit as a condition of the tenancy, so the landlord often sets the figure.

Mobile and in-home services

Working in someone's home concentrates the risk in a small space.

Cleaners, gardeners and window cleaners
Mobile hairdressers, beauticians and nail technicians
Dog walkers, groomers and pet sitters
Personal trainers, tutors and carers
Appliance repair, locksmiths and handypeople

Events, markets and stalls

Market operators, festival organisers, councils and venue managers almost always require stallholders and suppliers to hold public liability cover before they will confirm a pitch, with the certificate checked on arrival.

Where other cover matters more

Consultants, designers, accountants, IT firms and agencies rarely injure anyone, but they can be sued for advice, designs or work that caused a client a financial loss. That is professional indemnity, not public liability. Businesses holding personal data or trading online should also look at cyber cover.

Many of these businesses still buy public liability because clients ask for it, particularly when attending client offices.

And the compulsory one

Once you employ anyone, employers' liability is required by law in the UK, with limited exemptions. Public liability and employers' liability are usually arranged together for that reason.
