Every builder knows that accidents happen on site. A visitor trips over a tool bag, a window gets cracked during a renovation, or a water pipe is damaged during groundwork. Without the right cover, these everyday incidents can turn into expensive legal claims that threaten your business. That’s where a robust builders insurance policy comes in. Understanding exactly what it covers helps you choose the right policy for the work you do.
That's where builders liability insurance comes in. Understanding exactly what it covers helps you choose the right policy for the work you do.
What Is Builders Liability Insurance?
Builders liability insurance is a type of tradesman insurance that protects you against claims made by third parties for personal injury or third party property damage connected to your work. The "third party" could be a client, a member of the public, a neighbouring property owner, or anyone else who is not you or your employees.
Most builders take out builders public liability insurance as the core part of their insurance policy. This handles the legal costs and compensation payments that can arise when something goes wrong on a construction site. Public liability insurance cover for tradespeople can be arranged with limits of up to £25 million, depending on the nature and scale of your work.
What Does Builders Liability Insurance Actually Cover?
You may be asking: what does builders liability insurance cover and do I really need it? The answer is yes, and here is a clear breakdown.
Builders liability insurance typically covers the following:
Third-party bodily injury: If a client, visitor, or member of the public suffers an accidental injury because of your work or activity on site, the policy covers legal expenses and any compensation awarded against you.
Property damage: Accidental damage to a client's property, or to a neighbouring property, caused by your work is covered. This includes situations such as breaking a pipe that floods a property, cracking a wall, or damaging a roof during repairs. The policy covers repair costs for the damaged third party property.
Legal costs: Whether a claim is settled out of court or goes to a full legal dispute, builders liability insurance covers the solicitor fees, court costs, and any damages awarded.
Claims arising from completed work: If a problem emerges after a job is finished, such as a structural fault discovered months later, your policy can still respond to the claim under the products and completed operations section.

What Builders' Liability Insurance Does Not Cover
Builder's liability insurance does not cover damage to your own tools or equipment, which requires separate tools insurance. It also excludes injuries to your employees, which fall under employers' liability, faulty workmanship or the cost of redoing poor work, and any damage outside the scope of activities described in your policy.
This is why speaking to a specialist broker makes such a difference. Rather than buying a generic policy online, a broker can review exactly what you do and ensure your builders' liability insurance actually matches your work. If you also need cover for your tools, tools insurance for tradespeople can be added to the same policy for straightforward management.
Do Builders Need Liability Insurance by Law?
Public liability insurance cover for builders is not legally required in the same way that employers' liability insurance is. However, most main contractors, local authorities, and housing developers require you to hold minimum cover before you can start work on construction projects. Many contracts will specify a minimum of £1 million, with some commercial sites requiring £5 million or more.
Even if a client does not ask for it, the financial exposure of working without cover can be significant. A single personal injury claim on a domestic project can result in financial loss running into tens of thousands of pounds in legal expenses alone.
How Much Does Builders Insurance Cost?
The cost of builders liability insurance depends on several key factors, including the type of work you do, the contract value of your projects, the number of people working with you, and the level of cover you need. Your claims history and previous claims can also affect your premium, so maintaining a good safety record on site pays off.
At RAW Insurance, tradesman policies can start from as little as £80 including Insurance Premium Tax and fees for basic cover. Many insurance providers will vary premiums for builders working on larger commercial projects or requiring higher liability limits. The best way to get an accurate figure is to obtain multiple quotes through a direct conversation with a specialist rather than an online comparison.

Building a Complete Business Insurance Package
Builders liability insurance is usually the starting point, but a complete builders insurance policy for most builders will include additional covers. Public liability handles third-party claims, but your construction company has other exposures too.
If your building business has employees, even if they are casual workers or bona fide subcontractors under your direction, employers' liability insurance is legally required. Under UK law, failure to hold it can result in fines of up to £2,500 per day.
A comprehensive policy can also include contract works insurance, which protects building materials and work in progress on site against damage or theft, and hired plant insurance for any machinery or equipment you bring in for construction projects.
For builders who offer design, specification, or project management services alongside their physical work, professional indemnity insurance provides cover against professional negligence claims arising from advice or errors in design. You can bring all of these together under a single builders insurance policy, keeping your paperwork simple and your renewal dates aligned.
Frequently Asked Questions
Do I need builders liability insurance as a sole trader?
Yes. As a sole trader you are personally liable for any claims made against your work, which means your personal finances are at risk if something goes wrong on site. Builders liability insurance protects you whether you work alone or with a team, and many clients and contractors will require you to hold it before starting a job.
What's the difference between public liability and employers' liability insurance?
Public liability covers claims from third parties, such as clients or members of the public, who are injured or suffer property damage because of your work. Employers' liability covers claims from your own employees if they are injured or become ill as a result of their work. If you have anyone working for you, even on a casual basis, employers' liability is a legal requirement in the UK.
Does builders insurance cover subcontractors?
This depends on your policy wording. Some policies automatically extend cover to labour-only subcontractors working under your direct supervision, while others require you to declare them separately. It is important to check this with your broker before taking on subcontract labour, as a gap in cover here can leave you exposed to significant claims.
How much public liability cover do I actually need as a builder?
Most domestic projects require a minimum of £1 million in public liability cover, though £2 million is more common. Commercial contracts often require £5 million or more. If you are working for a local authority, housing association, or large main contractor, always check the contract requirements before agreeing to start work.
