PI insurance for UK family office and high-net-worth advisers

Reviewed by Apex Insurance Brokers · Published 14 July 2026

In short: Family office and HNW advisory work in the UK sits inside a specialist PI market. Cross-border structures, sophisticated clients, and complex asset arrangements create both higher potential claim quantum and specific coverage considerations. This page maps the specialist market.

Who this applies to

Multi-family offices serving multiple HNW client families with pooled infrastructure.
Single-family offices serving one principal family.
HNW-focused IFAs, wealth managers and discretionary managers.
HNW-focused legal advisers on private client, trust, and probate work.
Tax advisers serving HNW clients with complex UK/international structures.
Investment advisers serving sophisticated retail or professional clients under FCA rules.

Distinctive underwriting features

Higher potential claim quantum. HNW client wealth and complex structures mean individual losses can be materially higher than mainstream retail advice.
Cross-border exposure. UK-resident non-domiciled clients, offshore trusts, US-connected individuals, EU cross-border matters.
Regulatory overlap. FCA, HMRC, Bank of England PRA, plus overseas regulators.
Sophisticated-client classification. Some clients qualify as professional clients under COBS — different rules apply.
Long-tail advisory. Multi-generational advice creates extended limitation risk.

Regulatory landscape

FCA-authorised firms operate under MIPRU 3 / ICOBS 5A / COBS. Consumer Duty applies to retail clients even in HNW contexts.
DPB-regulated activity under ICAEW, ACCA, ATT, CIOT for accounting-firm advisers.
SRA MTC applies to solicitors doing HNW private-client work.
Trust and Company Service Provider (TCSP) rules apply to firms holding HNW client assets.
Anti-money-laundering and Beneficial Owner rules apply.

Cover-sizing considerations

HNW client assets and structures often support cover limits of £5m-£25m per claim; some family office arrangements require £50m+.
Aggregation across a family or across a family office's client base can materially compound single-loss exposure.
Cross-border cover extensions may be needed — territorial scope, jurisdictional limitations.
Layered programmes are the norm for material family office practices.
Reinstatement provisions matter given the aggregation risk.

Common claim triggers

Suitability challenges on complex investments. Alternative assets, private equity co-investment, unusual structures.
Tax-scheme advice. HMRC challenge to tax structuring, GAAR engagement, DAC6 issues.
Cross-border errors. UK/US treaty missteps, non-dom rules, offshore trust management.
Trustee errors. Where the firm acts as trustee or in trustee capacity.
Estate planning failure. Wills, IHT planning, transfer errors.
Cyber and data. HNW client data breach as targeted attack.

Insurer market

Specialist company market with HNW-focused underwriters.
Lloyd's syndicates specialising in professional-firm PII with HNW appetite.
Institutional captive arrangements for large multi-family offices.
Bespoke wordings often needed — cross-border extensions, high sub-limits, specific claims-handling protocols.

Frequently asked

What limit do family office advisers typically hold?

£5m-£25m per claim is common for mid-market family office work. Larger multi-family offices and single-family offices serving very-large-wealth families often carry £25m-£100m in layered programmes.

Are HNW advisers regulated differently from mainstream IFAs?

Same underlying FCA framework where the firm is FCA-authorised. Client classification (retail vs professional under COBS) matters materially — different rules apply to different client types. HNW does not automatically mean professional-client classification.

Do family offices need PI cover?

Yes typically. Even single-family offices serving one principal family carry PI cover — the family itself is the client, and errors can generate claims. Multi-family offices essentially always carry PI.

How does cross-border work affect PI?

Materially. Territorial scope of the policy must cover the jurisdictions the client operates in. US-connected clients attract particular attention. Some insurers restrict cover for specific jurisdictions.

What is TCSP and how does it interact with PI?

Trust and Company Service Provider regulation applies to firms providing trustee, corporate secretarial, or nominee services. TCSPs face specific supervision and PI expectations distinct from general professional advisory PI.

Do I need bespoke wording for a family office practice?

For material family office work, yes typically. Standard PI wordings may not address cross-border exposure, high aggregation, trustee-adjacent activity, or specific HNW-client scenarios. Specialist broker structures the placement.

How does Consumer Duty apply to HNW advice?

Where clients are classified as retail under COBS, Consumer Duty applies fully. Where classified as professional, PRIN 2A applies more narrowly. HNW does not automatically remove Consumer Duty; classification matters.

What about privacy and confidentiality for HNW clients?

Family office and HNW client confidentiality is paramount. PI must respond to confidentiality-breach claims. Cyber cover addresses the technical-breach exposure. Practical protocols matter as much as insurance.

How these figures are produced

This guide is built from Apex's own market data: the premiums insurers have actually quoted and charged on professional indemnity risks we have handled. Each night that data is aggregated into anonymised rate bands by profession, fee income and limit of indemnity. No client information is published — a band only appears where it contains at least five separate records, and unusually high premiums are excluded so a single atypical risk cannot distort the guide.

The range shown spans the typical spread of recent market outcomes for similar risks. Individual quotes can fall outside it in either direction. Figures exclude insurance premium tax at 12%.

This calculator is not a quote and is not an offer of insurance or advice. Your actual premium depends on full underwriting of your business, including your activities, claims record and insurer appetite at the time.
