Why Professional Indemnity and IR35 Insurance Go Hand in Hand for Contractors

Why Contractors Face More Than One Type of Risk

Operating through a limited company offers contractors flexibility, tax efficiency and independence, but it also brings greater responsibility. Alongside delivering specialist services to clients, contractors must manage commercial risks, comply with tax legislation and protect their business against potentially significant financial losses.

Two of the biggest risks facing UK contractors come from very different directions. Clients may pursue claims if professional advice or services result in financial loss, while HMRC may investigate whether a contract genuinely falls outside IR35.

Professional Indemnity Insurance and IR35 Insurance protect against these separate risks, but together they create one of the strongest risk management strategies available to contractors.

 

What Does Professional Indemnity Insurance Cover?

Professional Indemnity (PI) Insurance protects contractors against claims arising from professional mistakes, negligence, errors, omissions or breaches of duty.

Unlike Public Liability Insurance, which covers injury or property damage, PI Insurance protects the advice, expertise and intellectual services contractors provide.

Many recruitment agencies and end clients require contractors to hold Professional Indemnity Insurance before work begins, particularly in sectors such as IT, engineering, consultancy, project management and finance.

 

Common Professional Indemnity Claims

Typical claims include:

• An IT consultant implements software incorrectly, causing operational disruption
• A project manager provides inaccurate scheduling advice that delays delivery
• An engineer produces drawings requiring costly redesign
• A business consultant gives incorrect recommendations resulting in financial loss
• A contractor accidentally omits critical information from a client deliverable.

Professional Indemnity Insurance can cover legal defence costs, settlements and compensation payments, preventing a single claim from threatening the future of a contractor’s business.

 

What Does IR35 Insurance Cover?

IR35 Insurance protects contractors if HMRC opens an enquiry into their employment status. Even genuinely independent contractors can face lengthy investigations requiring specialist tax advice, legal representation and extensive evidence.

Defending an IR35 investigation can take many months, if not years, and incur substantial professional costs.

Depending on the policy, IR35 Insurance may include:

• Specialist representation throughout the investigation
• Tax investigation experts
• Legal defence costs
• Technical advice
• Support during appeals where appropriate.

For contractors working outside IR35, this protection can provide valuable financial security and peace of mind.

 

What Happens During an HMRC Investigation?

HMRC may request contracts, correspondence, invoices and evidence of working practices. Interviews may also be required, with investigators examining factors such as substitution, supervision, direction, control and mutuality of obligation.

Having experienced specialists managing the investigation allows contractors to focus on their business while ensuring their case is professionally presented.

 

Why These Two Policies Complement Each Other

Professional Indemnity Insurance and IR35 Insurance protect different aspects of the same business.

Professional Indemnity protects your commercial relationships.

IR35 Insurance protects your tax position.

Imagine an IT contractor delivering a twelve-month transformation project.

Following completion:

• The client alleges implementation errors caused £80,000 of additional costs
• HMRC simultaneously opens an IR35 enquiry into the engagement.

Without insurance, the contractor may need to fund legal defence against the client while also paying specialist tax advisers to defend their IR35 status.

With both policies in place, the contractor has protection on both fronts, significantly reducing financial exposure.

This demonstrates why the two products should be viewed as complementary rather than alternatives.

 

The Importance of an Independent IR35 Assessment

Insurance should form part of a wider compliance strategy.

One of the strongest ways to demonstrate reasonable care is to obtain an independent IR35 assessment before commencing an engagement.

The Contractor Compliance Portal enables contractors to assess both contractual terms and real-world working practices, producing detailed evidence to support an outside IR35 determination.

This documentation can prove invaluable should HMRC ever question a contractor’s status and complements the protection provided by IR35 Insurance.

Together, robust assessments and specialist insurance create a much stronger defence than relying on either in isolation.

 

Why Choose a Specialist Contractor Insurance Provider?

Contractors face unique risks that generic business insurance providers may not fully understand.

Choosing a specialist provider ensures policies are designed specifically for limited company contractors, freelancers and consultants working across a wide range of industries.

Roots Contractor Insurance specialises in contractor-focused insurance solutions, including Professional Indemnity Insurance, IR35 Insurance, Public Liability Insurance and Contractor Legal Expenses Insurance.

Combined with the independent IR35 assessments available through The Contractor Compliance Portal, contractors can build a comprehensive protection package covering both commercial and tax-related risks.

 

Frequently Asked Questions

Do I need both Professional Indemnity and IR35 Insurance?

If you work outside IR35 through your own limited company, the two policies protect entirely different risks. Professional Indemnity covers claims from clients, while IR35 Insurance protects against HMRC enquiries.

 

Does Professional Indemnity Insurance cover HMRC investigations?

No. Professional Indemnity Insurance is designed to respond to negligence or professional advice claims made by clients. HMRC investigations require specialist IR35 or tax investigation insurance.

 

Is an IR35 assessment still worthwhile if I have insurance?

Yes. An independent assessment demonstrates reasonable care and helps support your outside IR35 position. It also provides valuable evidence should HMRC ever investigate your engagement.
