Contract research laboratory insurance covers businesses that carry out research, testing or analysis for clients, including contract research organisations, analytical and testing labs and bioanalytical services. Because clients make decisions based on your results, professional indemnity is the most important cover. A wrong result, a lost sample or a missed deadline can lead to large claims, especially from pharmaceutical and food clients. Labs also need cover for client samples and materials in their care, deterioration of stock, equipment, business interruption and liability. Insurers look at the services you provide, your clients and their sectors, accreditation and quality systems, contract terms and liability caps, and how client samples are stored and tracked.

Running a contract research or testing lab? We'll arrange PI and property cover that reflects the reliance clients place on your work.

Key facts at a glance

  1. PI is the core cover. Clients rely on your results to make expensive decisions.
  2. Client samples need cover. Materials held for clients must be insured in your care.
  3. Contracts set the exposure. Liability caps and indemnities shape the risk.
  4. Accreditation helps. ISO 17025 and GLP or GMP status reassure insurers.
  5. Pharma clients raise the stakes. Errors in drug development work can be very costly.

What insurance does a contract research lab need?

A CRO or testing lab needs professional, property and liability covers working together.

Why do client contracts matter so much?

Large clients, especially pharmaceutical companies, often send contracts that ask the lab to accept wide or unlimited liability.

Your PI policy will only pay up to its limit, and it may not cover liabilities you agree to by contract that you wouldn't otherwise have. Before signing, check the liability cap, any indemnities, and the insurance clause. Where possible, cap liability at the fee or a multiple of it. Send contracts to us if you're unsure; it's much easier to fix wording before signature than after a claim.

Unlimited liability clauses

An uncapped indemnity in a client contract can leave you exposed beyond your insurance. Negotiate a cap or check with your broker before signing.

What do insurers ask a contract research lab?

  • Services. Analytical, bioanalytical, stability, microbiology or other testing
  • Clients. Sectors such as pharma, food, environmental or industrial
  • Fees. Income split by service and largest client
  • Accreditation. ISO 17025, GLP, GMP or others
  • Quality. Data integrity and sample tracking systems
  • Contracts. Standard terms and liability caps
  • History. Complaints, re-testing and claims

How can contract labs reduce their risk?

  1. Use your own terms. With sensible liability caps.
  2. Track samples. From receipt to disposal.
  3. Protect data integrity. Audit trails and secure systems.
  4. Keep accreditation current. And act on audit findings.
  5. Report issues early. Tell insurers about potential claims promptly.

Where the information comes from

Our articles are compiled from a range of sources: regulators and public bodies such as the FCA, the Civil Aviation Authority, the Health and Safety Executive and Companies House; government publications and legislation; industry and trade bodies; insurer and market documentation; and published research and news reporting. Not everything stated originates from Miller & Partner. Where information comes from a third party we believe it to be accurate at the date of publication, but we haven't independently verified every external source and we don't warrant its accuracy or completeness. Where a point matters to a decision you're making, go to the original source and check it.

Figures, examples and case studies

Premium ranges, cost figures, limits and worked examples are illustrative only. They are not quotations, not offers of cover, and no cover is provided or implied on the basis of them. What you're actually charged depends on underwriting, and what you're actually covered for depends on the policy wording issued to you. Where an article includes a claim example, scenario or case study, it is illustrative unless we say otherwise — such examples are typically composites written to show how a policy section responds, and they don't describe an identifiable client, claim or settlement.

Interactive tools

Any calculators, cover checkers, risk assessors or similar tools on our site produce general guidance from the small number of answers you give them. They can't see your business, and their output is not a personal recommendation, an assessment of your actual risk, or a quotation.

Rules and market conditions change

Law, regulation, tax treatment, insurer appetite and policy wordings all change, sometimes at short notice. Content is accurate to the best of our knowledge on the date shown on the article and we don't undertake to update it as things move. An article you're reading some time after publication may be out of date.

Third parties and external links

References to insurers, underwriters, trade bodies, software, training providers or other organisations are for information only. They don't imply endorsement, recommendation, partnership or affiliation in either direction unless stated. We're not responsible for the content of external websites we link to.

Not legal, tax or accounting advice

Nothing here is legal, tax, accounting or regulatory advice. Where an article discusses statutory duties, contract terms or compliance obligations, take advice from an appropriately qualified professional on your own position before acting.
