Sole practitioner cover

Sole practitioner cover is professional indemnity (PI) insurance arranged for a regulated professional who carries on business as an individual without a separate corporate or partnership vehicle, indemnifying the civil liability arising from the professional's own acts, errors, and omissions.

Definition §

A sole practitioner is a regulated professional who practises in their own name, taking on personal contractual obligations to clients and bearing unlimited personal liability for the consequences of professional negligence. The sole practitioner has no separate corporate or partnership shield; their personal assets are exposed to claims, and the PI policy is the only practical insulator between a successful claim and the practitioner's house, savings, and future income.^[1]

Sole practitioner cover is structured around this profile. The policy is written in the individual's name (or in the name of a sole trading style, with the individual identified as the principal). Cover responds to civil liability arising from the practitioner's own acts, errors, and omissions in the conduct of the professional business. Where the practitioner employs staff, the policy typically extends to the acts of employees performed in the course of their employment, although the principal remains personally liable as the contracting party.

The PI policy is normally arranged on a claims-made basis with prior acts cover going back to the date the sole practitioner first commenced practice. The retroactive date is therefore critical: a sole practitioner with 20 years' history needs a retroactive date that captures the entire span, since a claim could relate to any work done within the limitation period.^[2]

The financial exposure of a sole practitioner is materially different from that of a partner in a partnership or a member in an LLP. There is no firm to absorb claims, no other principals to share an excess, and no internal indemnity arrangement. As a result, sole practitioner cover is typically priced with that personal exposure in mind, and brokers usually advise on appropriate limits of indemnity that reflect the practitioner's full client base.

Legal / Regulatory basis §

The framework varies by profession. For solicitors, the Solicitors Act 1974 governs the right to practise and the SRA Indemnity Insurance Rules and SRA Minimum Terms and Conditions (MTC) prescribe the form of PI cover that sole practitioners must hold. The MTC require sole practitioners to maintain qualifying insurance with a per-claim limit of at least two million pounds.^[3]

For RICS surveyors, the RICS Rules of Conduct 2022 require all firms (including sole practitioners) to maintain PI cover meeting the RICS minimum standards, with limits set by reference to turnover.^[4]

For ICAEW chartered accountants in practice as sole practitioners, the ICAEW PII Regulations apply on the same basis as for larger firms.^[5]

For ARB-registered architects practising as sole practitioners, the ARB Code of Conduct requires adequate and appropriate PI cover.^[6]

For FCA-regulated insurance intermediaries, MIPRU 3.2.7R applies whether the firm is a sole trader or a corporate body, with the same minimum limits.^[7]

The Partnership Act 1890 is relevant by negative implication: a sole practitioner is not a partnership, and the joint-and-several liability provisions of the Act do not apply. The practitioner is solely liable in personal capacity.^[8] The Insurance Act 2015 governs the placement of the policy itself; the duty of fair presentation in sections 3 to 8 applies fully to sole practitioner placements, although in practice the disclosure exercise is concentrated on a single individual's history rather than that of multiple principals.^[9]

The Insolvency Act 1986 is relevant where the sole practitioner becomes bankrupt: the rights under the PI policy are not necessarily transferred to the trustee in bankruptcy, but third-party claimants may, under the Third Parties (Rights against Insurers) Act 2010, proceed directly against the insurer.^[10]

How it works in practice §

Placement begins with a proposal form completed by the sole practitioner. The form covers the practitioner's qualifications, length of practice, breakdown of work by discipline, fee income, claims history, and known circumstances. The disclosure exercise is more concentrated than for a multi-partner firm but no less rigorous; the practitioner's personal history is the only history.

The policy schedule names the practitioner as the insured and may also name any trading style. The retroactive date is set to capture the practitioner's full practising history. The limit of indemnity is selected to reflect the practitioner's largest realistic transaction value, with brokers typically recommending a margin of safety above bare regulatory minimums.

In claim handling, the policy responds to claims first made against the practitioner during the policy period and arising from acts after the retroactive date. The practitioner notifies the insurer of any claim or circumstance, cooperates with the conduct of defence, and consents to settlement decisions in accordance with the policy. The QC clause (or equivalent counsel arbitration mechanism) is often used to resolve disputes between insurer and insured about whether to settle a defensible claim.

On retirement or closure, the sole practitioner arranges run-off cover. For solicitors, the SRA MTC require six years of run-off, with post-six-year arrangements administered through the Solicitors Indemnity Fund (SIF) successor structures.^[3] For other professions, six years is the standard run-off period, although longer terms are commonly negotiated to capture latent claims under the Limitation Act 1980 and the Latent Damage Act 1986.^[2][11]

The sole practitioner faces particular continuity risks. If they fall ill or die, the firm has no continuing partners to maintain cover and pursue notifications. Brokers often advise on contingency arrangements, such as nominated successors or arrangements with another firm to take over the practice. Without such arrangements, the practitioner's estate or attorneys may need to manage run-off cover on the practitioner's behalf.

The sole practitioner's personal liability also creates particular interaction with the dishonesty exclusion. Where a sole practitioner is alleged to have acted dishonestly, no other principal can rely on an innocent partner provision, because there is no other principal. The MTC for solicitors address this by requiring qualifying insurance to respond to claims against innocent parties even where the sole practitioner is dishonest, but the protection is limited to claimants and does not protect the dishonest practitioner.^[3]

Common variations §

Variations include the choice of trading vehicle. A sole practitioner may operate as an unincorporated sole trader, in which case all personal assets are exposed. They may instead incorporate as a single-member limited company or single-member LLP, in which case the corporate shield provides some protection against contractual liability, although personal liability for the practitioner's own negligence typically survives the corporate veil. Each vehicle generates a different PI policy structure.

Some sole practitioners share office space, support staff, or branding with other practitioners under a chambers or office-sharing arrangement. Such arrangements do not create a partnership unless the practitioners share profits, but they can create coverage ambiguity. PI policies should be reviewed carefully to confirm that the cover responds only to the named individual's acts and that there is no inadvertent extension to other practitioners' work.

Sole practitioners who occasionally act as consultants to other firms (or who take on locum work) may need separate cover or an extension to address that activity. The host firm's policy may provide some protection, but the sole practitioner's own policy should also be considered.

For some professions, sole practitioner cover is harder to obtain at competitive rates because of the concentrated risk profile. Brokers often work with specialist underwriters who write sole practitioner business as a distinct category, with risk selection based on the practitioner's personal track record rather than the firm's broader portfolio.

Example §

A sole practitioner solicitor specialising in residential conveyancing has practised for 12 years. Their PI policy carries a per-claim limit of three million pounds, no aggregate limit, a retroactive date matching the start of practice, and the MTC wording. A client claims that the practitioner failed to identify a covenant restricting use of the purchased property. The claim, when received, is notified to the insurer; the insurer appoints defence solicitors; the practitioner cooperates with the defence under the policy. The insurer ultimately settles for 280,000 pounds plus costs, all within the per-claim limit. If the practitioner had instead retired the previous year, the run-off policy would have responded on the same basis.
