How Much Insurance Does a Sole Trader Need?

Ed Dixon Friday, 30 October 2026

The amount of insurance cover a sole trader needs depends on their trade, the value of the contracts they take on and the risks involved.

Key points

  • Sole traders should consider how much a claim might cost should something go wrong, and ensure their business is protected by insurance accordingly.

  • Having the right level of cover helps protect sole trader businesses in the UK against unexpected costs, compensation claims and financial liabilities.

  • The amount of insurance a sole trader needs depends on various factors. This includes the trade they’re in, the risks involved in their work, and the terms and conditions of the contracts they sign.

How much insurance does a sole trader need?

There is no simple answer to this question. It’s true that having the right insurance in place is highly valuable to any sole trader – but when it comes to which policies – and the limits of cover – we are in “how long is a piece of string?” territory.

The amount of insurance needed by a sole trader varies a lot. The following factors will all affect your insurance requirement if you’re a sole trader:

  • The nature of your work. The riskier it is, the more insurance cover you’ll need to smooth over whatever may go wrong. Find out how insurers determine the risk of your trade here.

  • The potential cost of a claim. Your cover needs to be sufficient to cover the potential cost of claims made against you

  • Whether or not you’re offering advice. If you provide professional advice as part of your services, you may need a policy to cover this should it backfire.

  • Whether you’re an employer. Whether you employ any staff within your sole trader enterprise affects which cover you need.

For example, a sole trader carrying out lower-risk work (such as assembling furniture) may need less Public Liability Insurance cover than a builder working at height or an electrician navigating complex wiring systems. Consider the potential financial impact of an accident or claim when deciding how much cover your business needs (or talk to Rhino – we can take the guesswork out for you).

What level of public liability cover is typical for sole traders?

Again – it depends. Public Liability Insurance protects sole traders against the financial impact of claims for injury to third parties, or damage to third party property arising from their business activities. The upper cover limit for this insurance usually varies from £1 million up to £5 million, although the amount you choose as a sole trader will depend on your trade and the risks it carries.

A limit of cover on the higher side may be appropriate where a claim could involve substantial injuries, property damage or significant legal costs. Think of it this way – if there’s a genuine chance someone could get badly hurt or even die as a result of what you do, then you’ll need a policy limit that reflects this eventuality.

Often, public sector bodies and commercial clients in the UK will have specific requirements as to how much Public Liability Insurance you’ll need before they’ll work with you. It’s important to check contractual requirements carefully before agreeing to take on a new customer or contract.

Does the amount of cover depend on the trade or contract size?

Both. Firstly, different trades face different risks, meaning that riskier trades may require more cover and higher indemnity limits. For example, an electrician working on a large commercial site may face more risk than someone painting internal walls in a private home, meaning the sparky would likely need more cover.

  • The size and nature of a contract can also influence the level of insurance required. For example, a contractor working for a major company may need higher public liability limits than someone working exclusively for private customers.

  • You should consider:

  • The potential severity of a claim

  • The value of the property or equipment you work with

  • The activities involved

  • The conditions of insurance specified in your contract.

Choosing insurance cover that reflects these factors helps ensure your business is fully protected. Remember – Rhino are here to guide you through our straightforward process to discover the insurance types and limits that are right for you.

Can sole traders adjust their cover as their business grows?

Yes. As a sole trader, your insurance needs may change as your business does. If you start to take on larger contracts for example, begin to offer new services, take on staff or branch out into a new customer base (e.g., commercial rather than private), you will need to adjust your insurance to fit the new status quo of your sole trader business.

Review your policies regularly, at least once per year, to ensure that your cover levels are still plenty to cover the risks you face as a sole trader. Review them more frequently if your business circumstances change to avoid unwanted nasty surprises. For example, as soon as you decide to employ staff, you need Employer’s Liability Insurance in place to be legally compliant.

Are there minimum cover levels set by clients or contracts?

Yes. Some clients, contractors and commercial organisations specify minimum insurance requirements in their contracts before allowing a sole trader to work with them.

Projects may also ask to see proof of your Employers' Liability Insurance, Professional Indemnity or other specialist insurance types, depending on the work involved and the contract terms.
