What is liability insurance?
Liability insurance pays compensation and legal costs when a business is held responsible for injury, illness, damage or financial loss suffered by someone else. Each type answers a different kind of claim: from the public, from employees, from customers relying on your products or advice, or against directors personally.
Most established firms hold several liability covers at once. Employers' and public liability are the usual starting point, often written together or inside a commercial combined policy. Professional, management, cyber and environmental covers are then added according to what the business does, who it contracts with and how it is run.
The skill is in choosing limits and making sure the policies meet without gaps, which is where a specialist commercial broker earns their keep.

How much does liability insurance cost?
Each liability policy is priced on its own measure of exposure, so there is no single figure. These are the factors that move the premiums most across the range.
What the business does
Hazardous processes, work at height, heat work and work at customers' premises weigh more than office activity. Insurers rate the riskiest part of what you do, not the average.
Turnover and wage roll
Public and products liability usually follow turnover, employers' liability follows wages. Both are often adjusted to actual figures after the policy year.
Limit of indemnity
Higher limits cost more, but the increase is rarely proportional. Matching the limit to contracts and realistic claims avoids paying for cover you cannot use.
Where you trade
Exports and work overseas, particularly to North America, change the rating of products and public liability considerably.
Claims record
Frequency matters as much as size. Several small claims can concern an insurer more than one large one with a clear explanation.
Risk management
Health and safety systems, subcontractor checks, contract terms, quality control and cyber controls are all reviewed, and evidence of them helps.
Where liability policies leave gaps
No liability policy covers everything. These are the gaps that catch firms out, and the cover that usually fills each one.
- Advice, design and specification errors under public liability, which need professional indemnity cover
- The cost of recalling or replacing your own faulty products, which falls to product recall insurance
- Gradual pollution, as most public liability policies cover only sudden, identifiable, unintended and unexpected incidents; environmental liability goes further
- Liability you accept under a contract beyond what you would owe anyway, unless the insurer has agreed it
- Vehicles used on the road, which belong under a fleet policy or motor cover
- Data breaches and network failures, which need a cyber policy
- Work or exports in territories not shown on the schedule
- Claims against directors personally, which sit under directors' and officers' insurance
Public liability or professional indemnity?
These two are confused more than any other pair. The difference is the type of loss, not the type of business.
| Feature | Public liability | Professional indemnity |
|---|---|---|
| Claims it answers | Physical injury to people and damage to their property | Financial loss caused by your advice, design or service |
| Typical example | A visitor trips over cabling in your premises | A client loses money after relying on a flawed report |
| How claims are handled | Usually on the date the incident happened | Usually on the date the claim is made, so cover must stay in force |
| Who usually needs it | Firms with premises, visitors or work at customers' sites | Firms that advise, design, specify or certify |
| Asked for by | Main contractors, landlords and venues | Clients, professional bodies and lenders |
| Can be combined | Often with employers' and products liability | Sometimes packaged with technology or management cover |
How to choose the right liability cover
A short review of your activities and contracts tells you which policies you need and at what limits.
Map who could claim
Staff, visitors, customers, clients relying on your advice, shareholders and anyone affected by pollution or a data breach.
Collect your contract terms
Note the limits and covers that customers, main contractors, landlords and lenders require of you.
Check what you already hold
A combined or package policy may already include employers', public and products liability, so review the schedule first.
Agree sensible limits
Set each limit on the largest realistic claim and your contract terms, not on a default figure.
Compare the gaps, not just prices
Look at territorial limits, heat and height conditions, contract exclusions and whether policies are written on a claims made or occurrence basis.

Compare quotesChoosing liability insurance: FAQs
Which liability insurance does my business need?
Most firms with staff start with employers' and public liability, and add products liability if they make, sell or import goods. Professional indemnity follows if you advise or design, and D and O or management liability once there is a board and outside investors or lenders.
Is any liability insurance compulsory?
Employers' liability is compulsory for most businesses with employees, and the certificate must be available to staff. Other liability covers are not compulsory in general, but contracts, landlords, trade bodies and clients frequently make them a condition of doing business.
What is the difference between D and O and management liability insurance?
Directors' and officers' insurance protects individual directors and the company's obligation to indemnify them. Management liability is a wider package that usually adds employment practices liability and corporate legal liability, and sometimes crime cover. Larger firms often buy D and O on its own with higher limits.
Do I need product recall cover if I already have products liability?
Products liability pays for injury or damage your goods cause to others; it does not pay to withdraw them. Recall insurance covers the cost of the recall itself, lost profit and often consultants' fees. Food, drink, automotive and consumer goods firms are the usual buyers.
Can I put all my liability covers on one policy?
Employers', public and products liability are routinely written together, often inside a combined policy. Professional indemnity, D and O, cyber and environmental cover are usually separate policies with specialist insurers, though some packages bundle them for particular sectors.
How much liability cover do I need?
Look first at your contracts, which often set a minimum limit, then at the largest claim your activities could realistically produce. Employers' liability must meet a minimum limit, and most insurers include more than that as standard. A broker can test your chosen limits against claims in your sector.
Does public liability cover injuries to my own staff?
No. Injuries and illness suffered by employees through their work are claims under employers' liability. Public liability covers third parties, such as visitors, customers and members of the public, and damage to their property.
How much does liability insurance cost?
It depends on what you do, your turnover and wage roll, the limits you choose, where you trade and your claims record. Because each policy is rated differently, the mix of covers you buy has more effect on the total than the size of the firm alone.
How do I get a liability insurance quote?
Start with the quote button above; a specialist commercial broker picks it up from there. Have a description of your activities, turnover, wage roll, any contract requirements and five years of claims details ready so they can approach the right insurers.
