Builders insurance helps cover financial losses if something goes wrong on site, whether it’s an accident, property damage, theft or an injury claim. If you work in construction, it’s one of the most important things to have in place before you start any job.
Whether you’re self-employed, run a small team or manage larger projects, the right insurance protects you from the unexpected – and can help you win more work. In this guide, we’ll explain what it covers, why it matters and how you can find and fund the right policy for your work.
Construction work is full of moving parts. Even with careful planning, there’s always a risk that something might not go as expected. Insurance for builders protects you against financial risks such as on-site accidents, damage to a client’s property, or stolen tools.
Then there’s the perception aspect (an intangible but vital part of securing new work). Having cover in place tells clients that you’re serious about safety and responsibility.
Builders insurance isn’t just about reassurance, though. It’s a requirement in some cases. Contractors and local authorities often ask for proof of insurance before you can start a job.
The right builders insurance helps protect you from the financial aftershocks caused by:
In short, builders insurance protects your reputation, your finances and your ability to keep working.
No law requires every builder to have full commercial builders insurance. But it's often essential in practice. Many clients won’t let you on site without proof of builders insurance, and some contracts specify minimum cover levels.
If you employ anyone – even part-time or temporary staff – you must have employers’ liability insurance by law. This protects you if an employee is injured or becomes ill because of their work.
There are several types of insurance for builders, each designed to cover a different risk area. You can often combine them into one policy package to suit your needs.
Public liability insurance
This covers injury or property damage claims made by third parties – for example, if a passer-by is injured by falling debris or you accidentally damage a client’s property.
Builders risk insurance (AKA contract works insurance)
This protects the work in progress, along with tools, equipment and materials on site. If there’s a fire, flood or theft, this cover helps you recover the cost of replacing or repairing what’s been lost or damaged.
Employers’ liability insurance
If you employ anyone, this is a legal requirement. It protects you from claims if an employee gets injured or falls ill as a result of their work.
Professional indemnity insurance
If you offer design or advisory services, this cover protects you against claims related to professional mistakes or omissions – for example, if your design advice leads to costly rework.
Tool and equipment insurance
This protects your tools against theft, loss or accidental damage, whether they’re kept on site, in your van or at home.
Public liability covers injuries or damage caused to other people or their property because of your work. Builders risk, on the other hand, covers the project itself – the building materials, tools and unfinished works.
In most cases, you’ll want both. That way, you’re covered for incidents affecting others as well as damage to your own materials and progress.
If you’re a sole trader or self-employed builder, you’re not legally required to hold all types of cover – but it’s still worth it.
Even without employees, having public liability insurance protects you if something goes wrong on site. Many clients will expect you to have it before hiring you. Tool insurance is another smart choice if you rely on your equipment to work. Losing tools to theft or damage can be both costly and disruptive.
As a minimum, consider: Public liability insurance (for accidents or property damage involving third parties), tool and equipment cover (for theft or loss), personal accident cover if you’re unable to work because of injury, and, if you provide design or project advice, professional indemnity insurance may also be useful.
The cost of builders insurance depends on a few key factors, such as:
A small self-employed builder might pay less than £200 per year for basic public liability insurance, while larger contractors with multiple employees and vehicles could pay several thousand.
When comparing builders insurance quotes, consider the level of protection you need rather than just opting for the cheapest policy. The right cover can save you far more in the long run if something goes wrong.
The best way to find suitable builders insurance in the UK is to compare multiple providers. Specialist brokers can help you find policies tailored to construction work, while online comparison tools give you a quick overview of prices and options.
When applying for quotes, be clear about the types of projects you undertake and your safety procedures. A good claims history and clear risk management can help reduce your premiums.
Tailor your policy to your actual needs – if you only work on small domestic jobs, there’s no need to pay for cover designed for large commercial sites. On the other hand, be sure not to leave any gaps in protection just to save on costs.
Paying annual premiums upfront saves money in the long run – but it can strain your cash flow now (especially if you’re juggling multiple projects). Some insurers offer monthly payments, but they can include extra interest or fees.
If you want more flexibility, an iwoca small business loan can help you manage these kinds of costs more easily. You can borrow from £1,000 to £1,000,000, with no early repayment fees and the option to repay as soon as you like.
That way, you can spread the cost of essentials such as builders insurance, materials, or tools without locking up your working capital. We’ve designed the Flexi-Loan to help you stay in control – so you can keep projects running smoothly and focus on what you do best.
