PAT Tester Insurance: Cover, Requirements and Quotes
On this page
Insurance should match the PAT work you actually undertake. Public liability, professional indemnity and tools cover serve different purposes, while legal duties and client contract requirements must be checked separately.
The information below helps you discuss the scope with an insurer or broker; it is not a statement that every tester needs one fixed package or limit.
The four types of insurance most PAT testers need
Public liability insurance
The foundation. Covers you if your testing work causes harm or damage to a third party — typically:
- Injury to a client or member of public during your testing
- Damage to client property during testing
- Consequential losses arising from your work
Choose a public-liability limit appropriate to the work and any customer contract. Ask the insurer or broker what is covered, what is excluded and whether the proposed limit meets those requirements.
Professional indemnity insurance
Covers you if your professional advice or services cause financial loss to a client. For PAT testing specifically:
- Failed appliance testing missed during your work
- Incorrect classification of an appliance leading to inappropriate testing
- Errors in certification leading to client compliance failures
- Wrongful advice on testing frequency or appliance disposal
Agree a professional-indemnity limit and policy terms suited to your inspection, reporting and advice activities. Customer contracts may specify a limit; there is no single amount that fits every PAT business.
Tools and equipment cover
Tools cover can protect suitable equipment against specified theft, damage or loss. Check replacement values, security conditions, excesses and whether calibration or other restoration costs are included; do not assume ordinary maintenance is insured.
Standard approach: separate tools cover (£500-£3,000 covered) or extended coverage as part of business contents insurance.
Vehicle cover (for business use)
Tell your motor insurer about travel between work sites and obtain the appropriate business-use cover. Insurers’ class names and permitted uses differ, so check the actual policy.
What's not covered
A few things that PAT testers sometimes assume are covered but aren't:
Direct work-related injuries to yourself
Public liability covers injuries to others. If you're injured at a client site testing equipment, your standard insurance won't cover lost income or treatment costs. You'd need separate personal accident or income protection insurance.
Equipment damage caused by faulty testing
If your test damages a client's appliance (rare but possible — particularly with sensitive electronics on full insulation testing), professional indemnity may cover it. Public liability typically won't.
Failure of your own testing skills
Professional indemnity covers errors of professional judgment but doesn't cover deliberate negligence or fraud. If you certify equipment as safe that you knew was dangerous, no insurance will help.
Loss of business if you can't work
Sickness, accident, or family emergency that takes you out of work for weeks isn't covered by any business insurance. Income protection insurance handles this separately.
Getting a comparable insurance quote
Obtain a quote for your actual activities, turnover, employees, equipment, claims history and requested cover. A general price range cannot tell you what a policy will cost for your business.
Compare limits, excesses, exclusions, retroactive dates and whether claims are covered on a claims-made basis, as well as the premium.
What insurance providers ask about
When applying for PAT tester insurance, expect questions about:
- Relevant training and practical competence for the agreed work; confirm any specific qualification required by the customer.
- Years of experience
- Annual revenue from PAT testing
- Maximum value of equipment you typically work on
- Types of premises you work in (commercial, residential, industrial, special)
- History of any previous claims
- Whether you provide professional indemnity-relevant advice (testing frequency recommendations, equipment classifications, etc.)
- Geographic area of operation
Honest answers reduce the risk of policy dispute later. Cheap insurance from a comparison site that didn't ask the right questions is the worst-of-all-worlds because cover may be invalid when you need it.
Working without insurance
A claim can create substantial costs. Some clients require particular cover before work starts, but public liability and professional indemnity are not automatically universal statutory requirements for every PAT tester.
If you employ staff, check the employers’ liability insurance rules and exemptions. Separately confirm that your vehicle policy covers the journeys and business activities involved.
Catastrophic claims
A single fire traceable to an appliance you certified as safe could lead to:
- Potential property-damage and interruption costs, depending on the incident and the policy.
- Personal liability where you're held responsible
- Loss of all personal assets
Client losses
Most professional clients (commercial, HMO, holiday lets, schools) require evidence of insurance before engaging you. Without it, you simply can't compete for that work.
Personal risk
Even for sole-trader work, an accident or negligence claim against your name is yours personally, not just business-related. Without insurance, judgments against you become personal debts.
Insurance premiums and potential claims vary substantially. Compare suitable policies and the financial exposure of the work rather than relying on a generic break-even calculation.
Special considerations
The role of qualifications in insurance
Ask the insurer which competence evidence it needs for the activities being insured. A named award is not a universal condition of every policy. Describe your actual training and experience accurately and confirm any exclusions for specialist work.
Documentation requirements
A PAT course can help develop inspection and testing skills. Competence also depends on practical ability, experience, the equipment involved and understanding the results. Successful learners on our classroom course receive a Skills Training Group certificate within one working day. Check the course scope and arrange additional training or specialist assistance for work outside it. See the course details and available locations.
Describe your work accurately, including any specialist equipment or high-risk sites, employees, subcontractors and work performed away from your premises. Ask which activities are included and what training or competence evidence the insurer requires.
If cover is claims-made, discuss continuity and run-off needs when changing insurer or stopping work. There is no single suitable run-off period for every business.
Frequently asked questions
Is public liability legally compulsory for PAT testing?
It is commonly useful and may be required by a client contract, but there is no general PAT-specific statutory public-liability requirement stated here. Employers’ liability and motor-insurance duties are separate.
What limits should I choose?
Choose them with the insurer or broker using the work, client requirements and potential losses. A universal £2 million or £250,000 minimum cannot be assumed.
Will a course certificate guarantee cover?
No. The insurer assesses the actual activities, competence evidence and policy conditions.
How much will it cost?
Get a current quote based on the complete scope. Unsourced generic premiums are not a reliable budget.
The takeaway
Agree the scope and limits with an insurer or broker, meet the legal duties that apply to your business and understand exclusions before taking on work. Insurance does not replace competent testing and safe working.
