Professional indemnity insurance for consultants UK 2026

What consultants pay for PI cover in 2026

Professional indemnity (PI) insurance for a typical UK consultant costs between £150 and £400 a year for £1 million of cover in 2026. Low-risk, desk-based disciplines — HR, training, marketing — regularly find £1m policies from around £7–£8 a month, while higher-risk fields such as engineering design or financial consulting are usually quoted £500–£1,000 or more. Your premium is rated on fee income, discipline, cover limit, claims history and contract terms, not a flat tariff, so two consultants with identical job titles can pay very different prices.

Most consultants buy £1m–£2m of cover because that is what client contracts and public-sector frameworks demand before work can start. For the full market picture across every profession — not just consulting — see our professional indemnity insurance cost guide for 2026.

What consultant PI insurance covers — and what moves the price

What it covers. PI insurance responds when a client claims your professional advice or services caused them financial loss. For consultants that typically means:

• Negligence and errors: a flawed recommendation, a mis-scoped project, a missed dependency that costs the client money.
• Breach of duty or contract terms: failing to deliver to the professional standard your engagement letter promises.
• Confidentiality and IP slips: unintentional disclosure of client information or accidental copyright infringement in deliverables.
• Defamation and lost documents or data arising from your professional work.
• Legal defence costs — often the largest exposure, payable even when a claim ultimately fails.

Who actually needs it. For most consultants PI is not a legal requirement, but it is a commercial one. Corporate procurement teams and public-sector frameworks routinely demand proof of £1m–£2m before a purchase order is raised, and regulated professions carry mandatory minimums: ICAEW requires accountancy firms to hold at least £2m, RICS scales its minimum with firm turnover, and FCA-authorised intermediaries must meet the limits set in the FCA Handbook (IPRU-INV). If your clients are large organisations, assume the contract will specify a limit — and read it before you buy.

What moves the price. Insurers rate consultant PI on fee income (bigger books of business mean bigger potential claims), discipline risk (advice that moves large sums or safety-critical designs costs more to insure), the cover limit, your claims history, the excess you choose, and even contract type — bespoke liability clauses and US exposure both push premiums up. The cheapest wins are usually a sensible voluntary excess, paying annually rather than monthly, and re-quoting at renewal instead of rolling over.
