Do tradespeople need public liability insurance?

Public liability insurance is one of those things most tradespeople know they should probably have but aren't quite sure whether they have to. The short version: it's usually not a legal requirement for a sole trader, but plenty of customers, contracts and trade schemes won't deal with you without it, and one accident without it can wipe you out. Here is what it actually covers, when you genuinely need it, and the trades that need more on top. This is general information, not legal or financial advice, so check your own situation and speak to an insurer.

What public liability insurance covers

Public liability insurance covers you if your work injures someone or damages their property, and they make a claim against you. Think of the realistic disasters: a tool dropped from height, a flood from a fitting that fails, a customer tripping over your gear, a fire traced back to your work. The policy covers the compensation and the legal costs of defending the claim. For a trade working in other people's homes and businesses, those are exactly the things that can and do go wrong, and the cost of a serious claim can be far more than the work was ever worth.

Is it a legal requirement?

For a sole trader, public liability insurance is generally not required by law. You can legally trade without it. That's different from employers' liability insurance, which is a legal requirement once you employ staff, even casually, with limited exceptions. So the honest answer to "do I have to have it?" is usually no, not by law. But "not legally required" and "safe to go without" are not the same thing, and that's where most trades get caught out.

When you'll need it anyway

Even though the law doesn't force it, plenty of other things do. In practice, you'll often find you can't work without it:

• Many customers, especially businesses, landlords and larger clients, won't hire a trade who can't show cover.
• Main contractors almost always require it before they'll let you on site, and will ask for proof.
• Trade bodies, competent-person schemes and accreditations often make it a condition of membership.
• Some commercial and public-sector contracts specify a minimum level of cover you must hold.
• It's a basic mark of being a professional business, and increasingly customers simply expect it.

So while no law compels it, going without can quietly shut you out of a lot of work, and it leaves you personally exposed to a claim that could cost more than you have.

Some trades need extra cover

Public liability is the baseline, but it isn't the whole picture, and the right mix depends on your trade and how you work. Depending on what you do, you may need more on top:

• Employers' liability if you have any staff, which is the legal requirement mentioned above.
• Professional indemnity if you give design or advice as part of your work, not just carry it out.
• Tools and plant cover, since public liability won't replace your own kit if it's stolen or damaged.
• Higher levels of cover for certain work, sites or contracts that specify a minimum.
• Trade-specific considerations, for example heat-work or higher-risk activities an insurer wants to know about.

How to decide for your own situation

Don't treat any of this as a yes-or-no rule that fits everyone. Look at who your customers are, the sites you work on, the schemes you belong to, and the realistic worst case if something goes wrong on a job. Then talk to an insurer or a broker who knows your trade and get cover that matches how you actually work. The point isn't to tick a legal box, it's to make sure one bad day doesn't end your business. It's also worth noting your cover on your paperwork where relevant, because it tells customers they're dealing with a proper business.
