Summary

Insurance is the single most important overhead a tradesperson needs to budget for. Public liability insurance protects you if your work causes injury to a member of the public or damage to someone else's property -- a burst pipe flooding a customer's kitchen, a ladder falling onto a parked car, or a passer-by tripping over your materials. Employer's liability is the only insurance that is legally compulsory, kicking in the moment you take on staff. Beyond those two, professional indemnity insurance covers you if your advice or design work causes a client financial loss, while tool cover and contract works insurance protect your livelihood and the jobs you are working on. Most tradespeople can get a comprehensive package covering all of these for somewhere between £30 and £80 per month, depending on trade and risk level.

Key Facts

  • Public liability insurance is not a legal requirement in the UK, but most customers, main contractors, and local authorities will refuse to hire you without it.
  • Employer's liability insurance is a legal requirement if you employ anyone -- the minimum cover is £5 million, and the fine for non-compliance is up to £2,500 for every day you are uninsured.
  • Most main contractors require subcontractors to hold at least £2 million in public liability cover; many require £5 million, and local authorities often insist on £10 million.
  • Professional indemnity insurance is not legally required for tradespeople, but is strongly recommended if you carry out any design work, provide specifications, or give technical advice.
  • Tool theft costs UK tradespeople an estimated £99 million per year, with 94% of stolen tools never recovered.
  • Standard van insurance typically does not cover tools left in the vehicle -- you need separate tool cover or a specific add-on.
  • Contract works insurance (also called contractors' all risks) covers materials and labour on site against fire, flood, theft, and accidental damage during the build.
  • Insurance premiums are tax-deductible as a business expense.

Note: Many insurers offer combined tradesperson packages that bundle several of these covers together at a lower total cost than buying them separately.

Detailed Guidance

What is public liability insurance and do I need it?

Public liability insurance covers your legal liability if your work causes injury to a member of the public or damage to third-party property. This includes customers, neighbours, passers-by -- anyone who is not your employee.

Typical scenarios it covers:

  • You accidentally drill through a water pipe and flood a customer's home
  • A member of the public trips over your tools or materials on a pavement
  • You damage a customer's existing flooring, furniture, or fittings while carrying out work
  • Dust or debris from your work damages a neighbour's car

Cover levels available:

  • £1 million -- suitable for very low-risk sole traders doing small domestic jobs
  • £2 million -- the most common level for domestic tradespeople; covers the vast majority of residential work
  • £5 million -- required by many main contractors and larger commercial clients; considered the industry standard for construction subcontractors
  • £10 million -- often required by local authorities, housing associations, and large commercial projects

Typical costs by trade (annual, £2m cover):

  • Painter/decorator, carpet fitter, locksmith: £50--£100
  • Plumber, joiner, carpenter: £60--£150
  • Electrician, gas engineer: £120--£200
  • General builder, roofer: £200--£500+

Higher cover levels cost more, but the jump from £2m to £5m is often only an extra £30--£80 per year -- well worth it if it opens the door to larger contracts.

Do you need it? Technically, no -- there is no law requiring it. In practice, yes. Almost every customer will ask if you are insured, most main contractors will not let you on site without proof of cover, and membership of trade bodies like the Federation of Master Builders (FMB) or Checkatrade requires it. Without public liability insurance, you are personally liable for any claim -- and a serious injury claim can easily reach six figures.

What is employer's liability insurance?

Employer's liability (EL) insurance is the only insurance that UK law requires you to have if you employ anyone. It covers your legal liability for injury or illness suffered by your employees during the course of their work.

Key legal requirements:

  • The Employers' Liability (Compulsory Insurance) Act 1969 requires every employer in Great Britain to hold EL insurance with a minimum cover of £5 million (most policies provide £10 million as standard)
  • You must display the certificate of insurance where employees can see it, or make it available electronically
  • The HSE (Health and Safety Executive) enforces the law and can inspect at any time

Who counts as an "employee"?

  • Full-time and part-time staff on your payroll
  • Apprentices
  • Temporary and casual workers
  • In some cases, labour-only subcontractors (if HMRC considers them to be employees for tax purposes)
  • Family members working in the business (unless they live with you and you are not a limited company)

Penalties for non-compliance:

  • £2,500 fine for every day you do not have valid EL insurance in place
  • £1,000 fine for failing to display the certificate or make it available to inspectors

Who is exempt?

  • Sole traders with no employees
  • Family businesses where all employees live with you (and the business is not a limited company)
  • Some public bodies

Typical cost: £70--£300 per year depending on the number of employees, what they do, and your claims history. The cost per employee is relatively modest -- usually between £50 and £100 per head per year for construction trades.

Do I need professional indemnity insurance?

Professional indemnity (PI) insurance protects you if a client suffers a financial loss because of your professional advice, designs, or specifications. It covers legal defence costs and any compensation you are ordered to pay.

You should seriously consider PI insurance if you:

  • Design heating, plumbing, or electrical systems
  • Prepare drawings or specifications for building work
  • Provide written advice that clients rely on to make decisions
  • Carry out feasibility studies or surveys
  • Specify materials, products, or methods
  • Inspect or certify building or construction works
  • Offer design-and-build services

Trades that commonly need it:

  • Architects and architectural technologists (required by ARB)
  • Structural engineers
  • Building surveyors and quantity surveyors
  • Electricians who design circuits and distributions
  • Heating engineers who design heating systems
  • General builders offering design-and-build packages
  • Kitchen and bathroom designers
  • Landscape designers

Cover levels: Typically range from £50,000 to £5 million. For most tradespeople doing design work alongside installation, £100,000 to £500,000 is usually sufficient. Check your contracts -- some clients will specify the minimum PI cover they require.

Typical cost: £150--£500 per year, depending on the cover level, your trade, and your turnover.

Important note: PI insurance is usually written on a "claims made" basis, meaning the policy that responds is the one in force when the claim is made, not when the work was done. This means you need to maintain cover continuously, even after completing a project. Most PI policies include "run-off" provisions, but check the terms.

What about tool and equipment insurance?

Your tools are your livelihood. If they are stolen or damaged, you cannot work -- and the cost of replacing a full van load of professional tools can easily run into thousands of pounds.

What standard van insurance covers: Most standard van insurance policies either do not cover tools at all, or provide only a very small amount of cover (often £150--£300). This is nowhere near enough for a working tradesperson.

What dedicated tool cover provides:

  • Theft from your van (including overnight, subject to security requirements)
  • Theft from site
  • Accidental damage
  • Tools in transit
  • Hired-in tools (optional)

Typical cover limits: £2,500 to £25,000+, depending on the policy. Make sure the limit matches the actual replacement cost of your tools.

Security requirements: Most policies require specific security measures to be in place for overnight van cover, such as:

  • Deadlocks or slamlocks on van doors
  • Tools stored in a locked toolbox or racking system within the van
  • Visible deterrents (no tools signage, tinted windows)
  • Some insurers require approved van locks (e.g. Locks4Vans)

Typical excess: £100--£500. Higher excess means lower premiums, but make sure you can afford the excess if you need to claim.

Typical cost: £50--£400 per year depending on the cover limit and security measures in place.

The scale of the problem: Tool theft costs UK tradespeople an estimated £99 million per year. "Peel and steal" attacks -- where van doors are forced open -- are the most common method. An average tool theft claim is worth over £3,000. Investing in good security and adequate insurance cover is essential.

How much cover do I need?

The right level of cover depends on your trade, the type of work you do, and who you work for.

For domestic work only (sole trader, residential customers):

  • Public liability: £2 million (minimum)
  • Employer's liability: £5 million (if you have employees -- legal minimum)
  • Tool cover: match to replacement value of your tools
  • Consider personal accident cover if self-employed

For subcontracting to main contractors:

  • Public liability: £5 million (industry standard; check each contractor's requirements)
  • Employer's liability: £10 million (most policies include this as standard)
  • Professional indemnity: £100,000--£500,000 if you do any design work
  • Contract works: enough to cover the maximum value of works you have on site at any time

For local authority or public sector work:

  • Public liability: £10 million (commonly required)
  • Employer's liability: £10 million
  • Professional indemnity: as specified in the tender documents
  • Contract works: as specified

For commercial or high-value residential work:

  • Public liability: £5--£10 million
  • Consider increasing all cover levels
  • Check the JCT or bespoke contract terms for specific insurance requirements

General rule: It is better to have slightly more cover than you think you need. The cost difference between £2m and £5m public liability is often only £30--£80 per year, but it can open the door to higher-value contracts.

What happens if I'm not insured and something goes wrong?

Without insurance, you are personally liable for the full cost of any claim. Here is what that looks like in practice:

Scenario 1: Property damage You are fitting a bathroom and accidentally rupture a water main, flooding the customer's ground floor. The damage to flooring, kitchen units, and personal belongings comes to £18,000. Without public liability insurance, you pay the full amount out of your own pocket -- plus the customer's legal costs if they have to take you to court.

Scenario 2: Personal injury A customer's child trips over your tools left in a hallway and breaks their arm. The family claims £25,000 in compensation plus £8,000 in legal costs. Without insurance, you are personally liable for the full £33,000. If the injury were more serious -- a head injury, a fall from height -- claims can reach £100,000 to £500,000 or more.

Scenario 3: Employer injury Your labourer falls from scaffolding and suffers a spinal injury. The compensation claim is £350,000. Without employer's liability insurance (which is illegal if you employ anyone), you face personal bankruptcy. You also face criminal prosecution and a fine of £2,500 per day for every day you were uninsured.

Scenario 4: Design failure You design and install a heating system. The system fails due to an undersized boiler, causing the customer to spend £4,500 on a replacement and losing rental income of £3,000 while the property is uninhabitable. Without professional indemnity insurance, you pay the full £7,500 plus legal costs.

Scenario 5: Tool theft Your van is broken into overnight and £5,000 worth of tools are stolen. Without tool cover, you cannot work until you replace them -- losing income on top of the replacement cost. Most tradespeople cannot absorb a £5,000 hit and continue operating normally.

The bottom line: Insurance for a typical sole trader plumber or electrician costs around £30--£60 per month. A single uninsured claim could cost tens or hundreds of thousands of pounds and end your business.

Frequently Asked Questions

Do I need insurance if I am a sole trader with no employees?

You do not legally need any insurance as a sole trader with no employees (employer's liability is only compulsory if you employ people). However, public liability insurance is strongly recommended for every tradesperson. Most customers, letting agents, property managers, and main contractors will require proof of insurance before letting you onto a job. Without it, you are personally liable for any damage or injury your work causes, with no cap on the amount you could owe.

Does my van insurance cover my tools?

Almost certainly not to an adequate level. Standard van insurance typically provides either no cover for tools and equipment, or a very small amount (£150--£300). If your tools are worth thousands of pounds -- as most working tradespeople's are -- you need separate tool cover, either as a standalone policy or as an add-on to a tradesperson insurance package.

Can I get insurance if I have had a claim in the past?

Yes. Having a previous claim will likely increase your premium, but it will not prevent you from getting cover. Be honest about your claims history on the application -- if you fail to disclose a previous claim and then make a new one, the insurer can refuse to pay out entirely.

Do I need insurance to join a trade body or scheme?

Most reputable trade bodies and accreditation schemes require public liability insurance as a condition of membership. Examples include Checkatrade, TrustMark, the Federation of Master Builders (FMB), the National Federation of Builders (NFB), and most competent person schemes. Check the specific requirements for any scheme you want to join.

What is the difference between public liability and professional indemnity?

Public liability covers physical injury to people and physical damage to property. Professional indemnity covers financial loss caused by your professional advice, designs, or specifications. For example, if you drop a tool on a customer's floor and crack a tile, that is a public liability claim. If you design a drainage system that does not meet regulations and the customer has to pay to have it redesigned and rebuilt, that is a professional indemnity claim.

Is insurance more expensive for certain trades?

Yes, significantly. Premiums are based on risk. Low-risk trades like painting and decorating, carpet fitting, or locksmithing pay the least. Medium-risk trades like plumbing, joinery, and electrical work sit in the middle. High-risk trades like roofing, demolition, scaffolding, and general building pay the most. Working at height, working with heat or flame, and working on occupied premises all increase the risk profile and therefore the cost.
