Why do you need builders insurance?

Builders insurance FAQ

Whether you’re new to buying business insurance or you’ve been trading for a while, here are the answers to some commonly asked questions about builders business insurance. You can also check out our business insurance FAQs.

In some situations you may need more than public liability to cover certain kinds of property damage. Learn about hired-in plant cover and contract works cover.

Make sure you cover the total cost of replacing all your tools or you’ll only get a proportion of your claim paid out if something happens to them. Learn about tools cover.

Depending on what you use to do your work, you may need other covers.

You may need more than tools insurance – for example, business equipment insurance if you have a work laptop, plant insurance if you use machinery.

Employers’ liability insurance is a legal requirement if you employ people.

If you have people working for you, including bona fide subcontractors (BFSC), labour-only subcontractors (LOSC), part-timers, or full-time staff, employers’ liability insurance is required by law.

Read on for our simplified guide to the difference between labour-only subcontractors and bona fide subcontractors.

Make sure you’re picking the right cover to protect you properly. It’s important to know that if you have another trade or job, you’ll need additional cover. For example, do you need to consider roofers insurance or bricklayer insurance?

If you provide other services, make sure you’re covered.

Other types of insurance

Think about the maximum possible loss your business could face in the event of a claim, and make sure you take legal fees and damages into consideration. You can choose from three levels of coverage – £1 million, £2 million, or up to £5 million.

Insurance companies calculate the price of your policy based on a range of factors. The quotes you get to compare will be based on your unique business. The following factors could affect the prices you’re quoted:

  • your claims history
  • how long you’ve been in business in this particular trade
  • if you work in dangerous environments
  • if you work with dangerous materials
  • the value of your tools, equipment or materials
  • the number of covers you want to include in your policy

If you have people working for you, employers’ liability insurance is required by law. While you may not be legally required to have other types of insurance, there are some covers builders may want to consider.

Being covered may be especially important if you want the added mark of trust you get from membership of a trade body or professional accreditation. Some trade bodies may require you to have a certain level of public liability or professional indemnity cover, for example.

You can set up your insurance before you begin trading. At this point you don’t need trade licences, but as soon as you begin trading, you’ll need to have any required licences in place.

Under the terms of your builders insurance policy, you’ll need to comply with all relevant rules and regulations for your insurance – and any claims you make – to be valid. Check which licences apply to your unique business using the government’s licence finder.

Whether you set up as a sole trader or a limited company, you’ll also need to register with HMRC (and Companies House if you form a limited company).

No, your builders insurance won’t cover you for poor workmanship. Depending on your policy, your builders insurance could cover you for things like:

  • third-party claims made against you for accidental injury or damage
  • theft or loss of your tools
  • claims made against you by an employee who has been accidentally injured or fallen ill as a result of working for you

We cover a range of builders and building types, from new builds to alterations on existing builds. We also cover a wide range of locations from domestic to commercial. If you’re completing a self-build or class yourself as a property developer, then please call our contact centre who can help you to find the best policy for your needs.
