Professional Indemnity Insurance for Medical Device Design: A Practical UK Guide

Introduction

Medical device design is high-stakes work. A small mistake in a specification, risk file, software requirement, or usability study can lead to delays, recalls, patient harm allegations, or a client’s lost revenue. Even when you’ve done everything “right”, you can still face claims about professional advice, design decisions, documentation, or regulatory support.

That’s where Professional Indemnity (PI) insurance comes in. PI is designed to protect your business when a client (or another party) alleges that your professional services caused them a financial loss. For medical device designers, PI is often a contractual requirement, and it can be the difference between a manageable dispute and a business-threatening legal bill.

This guide explains what PI insurance is, why it matters in medical device design, what it typically covers (and doesn’t), and how to choose limits and wording that match how you actually work.

What is Professional Indemnity insurance?

Professional Indemnity insurance covers claims arising from your professional services: your advice, design work, specifications, calculations, documentation, and other “intellectual” outputs.

In plain terms, PI helps pay for:

• Legal defence costs (solicitors, experts, court fees)
• Compensation/settlement amounts you become legally liable to pay
• Certain associated costs (depending on the policy wording)

PI is different from Public Liability (injury/property damage to third parties) and Product Liability (injury/damage caused by products you supply). Medical device businesses often need a combination of covers.

Why PI is especially important for medical device design

Medical devices sit at the intersection of engineering, clinical risk, software, human factors, and strict regulation. Claims can arise even when the device never reaches market.

Common drivers of PI claims in medical device design include:

• Regulatory delays and rework costs
• Alleged non-compliance with UKCA/CE requirements
• Design changes late in the project due to documentation gaps
• Software issues (including cybersecurity or data integrity concerns)
• Usability and human factors allegations
• Supplier and subcontractor errors (where you’re accused of poor oversight)

Because projects can be complex and multi-party, disputes can escalate quickly. PI helps you fund a defence and protect cash flow.

Who needs PI in medical device design?

PI is relevant for many roles across the medical device design lifecycle, including:

• Medical device design consultancies
• Product development and engineering firms
• Industrial design studios working on medical products
• Electronics and embedded systems designers
• Software and SaMD (Software as a Medical Device) developers
• Human factors/usability specialists
• Regulatory and quality consultants (QMS, technical files)
• Test and verification consultancies (where advice or reports are provided)
• Manufacturers providing design services for clients (ODM/OEM)

If you provide professional advice or design outputs to a client, PI should be on your radar.

Typical PI risks and claim scenarios (real-world examples)

Below are examples of the kinds of allegations that can trigger PI claims.

1) Specification or requirements errors

A client alleges that your requirements document was incomplete or incorrect, leading to a redesign, missed milestone payments, or a failed verification plan.

2) Risk management and documentation disputes

A client claims your risk management file (for example, hazard identification, risk controls, or benefit-risk rationale) was inadequate, causing regulatory rejection and costly remediation.

3) Human factors and usability allegations

If a device is difficult to use, a client may argue that the usability engineering work was insufficient, leading to additional studies, labelling changes, or market withdrawal.

4) Software defects and cybersecurity issues

For connected devices or SaMD, a defect might cause incorrect outputs, downtime, or data loss. Even if no patient harm occurs, the client may pursue costs for remediation and reputational damage.

5) Design transfer and manufacturing readiness

A client alleges that your design transfer package was incomplete, causing scrap, rework, or production delays.

6) Subcontractor and supplier oversight

You use specialist subcontractors (firmware, testing, clinical writing). If their work is challenged, the client may still pursue you as the prime contractor.

What PI insurance usually covers for medical device designers

Every policy is different, but PI commonly covers:

• Negligence: alleged failure to meet professional standards
• Breach of professional duty
• Misrepresentation (often unintentional)
• Defamation (in some wordings)
• Breach of confidentiality
• Infringement of intellectual property (often limited and wording-dependent)
• Loss of documents/data (wording-dependent)

For medical device design, the most relevant triggers are typically negligence, breach of duty, and documentation/advice disputes.

Defence costs: the hidden value

Even if you’ve done nothing wrong, you may still need to respond to a formal allegation. Defence costs can be substantial because medical device disputes often involve expert evidence and detailed technical review.

Many PI policies pay defence costs in addition to the limit of indemnity, but some include defence costs within the limit. That difference matters.

What PI insurance may not cover (common exclusions)

PI is not a “catch-all”. Common exclusions and limitations include:

• Known circumstances: issues you knew about before the policy started
• Deliberate wrongdoing or fraud
• Contractual liability: liabilities you accept in a contract that go beyond common law negligence
• Product liability/patient injury from a product you supply (usually separate cover)
• Fines and penalties (often not insurable)
• Warranty/guarantee promises (for example, guaranteeing regulatory approval)
• Cyber events (may require a cyber extension or separate cyber policy)
• Work outside your declared activities

Because medical device design often includes software and regulatory support, it’s important to check that your “business description” and activities are accurate.

PI vs Product Liability vs Clinical Trials cover (how they fit together)

Medical device businesses often need multiple policies:

• Professional Indemnity: design, advice, documentation, services
• Public & Product Liability: injury/property damage claims from products or operations
• Clinical Trials/Clinical Investigations insurance: where required for studies
• Cyber insurance: data breaches, ransomware, incident response
• Directors’ & Officers’ (D&O): management liability

A common mistake is assuming product liability will cover design advice disputes. It usually won’t.

How much PI cover do medical device designers need?

There isn’t a single “right” limit. It depends on your contracts, client profile, and risk.

When choosing a limit, consider:

• Contract requirements (many clients specify £1m, £2m, £5m, or higher)
• Typical project value and potential rework costs
• Whether you work on safety-critical devices or high-risk classifications
• Whether you support regulatory submissions
• Whether you work internationally (jurisdiction and litigation costs)

As a practical starting point, many UK design consultancies carry at least £1m–£2m, but higher limits may be appropriate for larger projects or higher-risk work.

Key policy features to look for (medical device design)

When comparing PI policies, pay attention to these details.

Claims-made basis and retroactive date

PI is usually written on a claims-made basis. That means the policy that responds is the one in force when the claim is made (not when the work was done), as long as the work falls within the retroactive date.

If you stop trading or change insurers, you may need run-off cover to protect past work.

Contractual liability and “fitness for purpose” clauses

Medical device contracts sometimes include tough clauses that can increase your exposure.

Watch for:

• “Fit for purpose” obligations
• Unlimited liability clauses
• Indemnities for consequential losses
• Guarantees of regulatory approval or timelines

PI can help, but insurers may restrict cover where you accept liabilities beyond negligence.

Worldwide jurisdiction

If you work with overseas clients or devices sold internationally, check territorial limits and jurisdiction clauses.

Subcontractors and consultants

Confirm whether the policy covers work performed by subcontractors under your control, and what conditions apply (for example, requiring them to carry their own PI).

Intellectual property cover

If you provide design work, there’s a risk of IP allegations (for example, copyright in drawings, patent disputes, or trade secrets). Some PI policies include limited IP infringement cover; others exclude it.

Cyber and data extensions

If you handle patient data, clinical data, or connected device software, consider whether your PI includes cyber extensions or whether you need a separate cyber policy.

Practical steps to reduce PI risk (and improve insurability)

Insurers like well-managed risk. These steps can reduce claims and often help pricing.

• Use clear scopes of work and change control
• Keep version control for drawings, requirements, and risk files
• Document assumptions and client decisions
• Use peer review and design review gates
• Maintain a robust QMS (even if not fully certified)
• Confirm responsibility split between you, the manufacturer, and the client
• Avoid promising outcomes you can’t control (like guaranteed approval)
• Keep records of advice and sign-offs

Good documentation doesn’t just help compliance; it helps defend claims.

What insurers will ask (so you can prepare)

When applying for PI, expect questions about:

• Your exact activities (design, software, regulatory, testing)
• Turnover and largest contracts n- Claims history and any known issues
• Contract terms (liability caps, indemnities)
• Quality processes and standards used
• Whether you work on implantable devices or high-risk products
• Where clients are based and where claims could be brought

Preparing clear answers speeds up quotes and reduces the risk of cover gaps.

Common mistakes to avoid when buying PI for medical device design

• Understating your activities (e.g., calling it “engineering consultancy” when you do regulatory support)
• Choosing the cheapest policy without checking exclusions
• Letting cover lapse (claims-made policies are unforgiving)
• Not aligning limits with contract requirements
• Signing contracts with unlimited liability without advice
• Assuming product liability covers professional advice

When PI is required by contract (and how to respond)

Many clients will ask for:

• A minimum PI limit (e.g., £2m)
• Evidence of cover (certificate)
• Cover maintained for a period after project completion (often 6–12 years)

If a client asks for long post-completion cover, discuss run-off and continuity with your broker. The key is to avoid a gap between what you promise contractually and what your insurance actually provides.

How to get a PI quote that fits your work

A good PI quote starts with a clear picture of your services.

Before you approach the market, gather:

• A short description of services (design, software, regulatory, testing)
• Typical client types and sectors
• Example contracts and liability clauses
• Turnover split by activity
• Any certifications (ISO 13485, ISO 27001, etc.)
• Details of subcontractor use

The more accurately you present your risk, the more likely you’ll get terms that respond when you need them.
