Business insurance is not a single product — it is a category covering multiple different risks that affect businesses and self-employed individuals in different ways. Getting cover right matters: both because some types are legally required, and because operating without appropriate cover exposes you to potentially business-ending liabilities.
This hub covers the main types of business insurance needed by UK businesses and self-employed workers in 2026: what each type covers, who legally needs what, typical costs, and how to work out what your business actually requires.
Business Insurance — What Exists and What It Covers
| Insurance type | What it covers | Who needs it |
|---|---|---|
| Employer’s liability | Injury or illness to employees | Legally required for all employers |
| Public liability | Injury or damage to third parties / public | Any business dealing with the public |
| Professional indemnity | Claims for negligent professional advice or service | Consultants, professionals, advisers |
| Product liability | Injury or damage caused by products you sell or make | Manufacturers, sellers |
| Business contents / equipment | Damage, theft, loss of business property | Any business with equipment or stock |
| Cyber insurance | Data breach, ransomware, cyber attack costs | Businesses holding customer data |
| Key person insurance | Financial loss if a key person dies or becomes critically ill | SMEs dependent on specific individuals |
| Business interruption | Lost income if business is forced to stop trading | Any business with fixed costs |
| Landlord insurance | Property used for letting | Property landlords |
The Legal Minimums
Employer’s liability insurance is the only business insurance required by law. Under the Employers’ Liability (Compulsory Insurance) Act 1969:
- Minimum cover: £5 million (most policies provide £10 million+)
- Must be from an FCA-authorised insurer
- Certificate must be available to employees (can be kept digitally)
- Applies to all employees, including part-time, temporary, and casual workers
- Penalty for non-compliance: up to £2,500/day
Motor insurance for any vehicle used for business purposes must include business use on the policy. Standard social, domestic, and pleasure motor cover does not extend to driving for business — check your existing policy if you use a personal vehicle for work.
Professional Indemnity — What You Need to Know
PI insurance covers the cost of defending a negligence claim and paying any compensation. It is essential for any business providing advice, professional services, or expertise.
| Profession/sector | PI typically required by |
|---|---|
| Financial advisers | FCA — mandatory |
| Solicitors | SRA — mandatory |
| Accountants | ICAEW/ACCA — mandatory |
| Architects and structural engineers | ARB/ICE — mandatory |
| Other consultants, IT, marketing | Contract requirement or good practice |
PI cover is typically purchased by annual limit (£250,000 / £500,000 / £1 million / £5 million). The right limit depends on the value of contracts you undertake and the potential scale of financial loss a client could suffer. Contracts may specify a minimum level.
Typical Business Insurance Costs in 2026
| Business type | Typical annual insurance cost |
|---|---|
| Sole trader consultant (PI + public liability) | £300–£800/year |
| Small professional services firm (5 staff) | £1,500–£5,000/year |
| Retail shop (employers, public liability, contents) | £1,000–£3,000/year |
| Tradesperson (public liability, tools, van) | £600–£2,000/year |
| Landlord (building, liability, loss of rent) | £200–£600/year per property |
What Landlord Insurance Covers
Landlord insurance is a specialist product combining building cover, contents (landlord’s own furnishings), property owners’ liability, and loss of rent. Key distinctions:
- Building insurance — structurally required if you have a mortgage; covers the structure against fire, flood, subsidence, and other perils
- Property owners’ liability — covers claims if a tenant or visitor is injured on the property
- Loss of rent — pays your rental income while the property is uninhabitable due to a covered event
- Malicious damage by tenants — an add-on that covers damage caused deliberately by occupants
Standard home insurance does not cover rented properties — you must switch to a landlord-specific policy as soon as you start letting.
Worked Example: Why PI Insurance Matters
Scenario: Charlotte runs a one-person IT consultancy. She implements a software migration for a client. A configuration error causes the client’s systems to be down for 48 hours, costing the client £120,000 in lost transactions.
The client sues Charlotte for £120,000 plus legal costs. Without PI insurance, Charlotte is personally liable (as a sole trader) for the entire amount, which would likely mean bankruptcy.
Charlotte’s PI insurance (£250,000 limit, costing £600/year) covers: her solicitor’s costs (£15,000) and the client’s compensation (£85,000 agreed settlement). Total payout: £100,000. Charlotte’s business survives.
