Sole practitioner solicitors, and small partnerships of two or three partners, sit in the part of the solicitor PI market most obviously affected by insurer appetite. The Solicitors Regulation Authority's Minimum Terms and Conditions (SRA MTC) apply to every SRA-regulated firm in England and Wales in the same way, whether the firm has one principal or thirty. The commercial reality of placing the risk, however, is different for a sole practice than a mid-sized firm — and different again at retirement, when six years of run-off cover become the practice's largest single financial obligation.
This page sets out how the market works for smaller solicitor firms, what the SRA MTC requires, and how Apex Insurance Brokers approaches the placement. It is written for solicitors already in practice on their own account, those considering setting up alone, and two- and three-partner practices told they sit below a specialist broker's partner minimum.
This page is for SRA-regulated law firms in England and Wales that fall into any of the following: a sole practitioner (one principal, trading as a sole trader, a single-director limited company or a recognised sole practice); a two-partner firm; or a three-partner firm. It covers general civil practice and niche disciplines — private client, conveyancing, family, employment, immigration, commercial, criminal and mixed practice all sit under the same MTC and qualifying insurer regime.
Solicitors regulated by the Law Society of Scotland are covered by the Master Policy administered by Lockton, not the SRA MTC. If that is you, go to our page on the Law Society of Scotland Master Policy.
The solicitor PI market is specialist — the SRA MTC imposes cover terms no ordinary commercial combined policy can meet, and only a defined list of participating insurers underwrites the risk on MTC-compliant paper. That list currently sits at around six to eight insurers, and composition shifts each October as insurers enter, exit or narrow appetite. Within that finite pool, insurers pick and choose on risk profile.
Sole practitioner firms and very small partnerships feel that pressure in three ways.
First, some specialist solicitor PI brokers set a partner minimum on their scheme — a rule that a firm must have at least four principals to qualify for the panel arrangement. That is a commercial choice by the broker and by the insurer providing the facility. It is not a comment on the underlying risk of the sole practitioner, but it does mean that a large body of one- to three-partner firms cannot access that route. For those firms, an individually placed quotation — approached insurer by insurer, on the merits of that specific practice — is the alternative.
Second, direct writers (the insurers that offer PI to accountants, consultants and other professions on a direct-to-firm basis) do not cover solicitors. The SRA MTC contains cover requirements that fall outside a standard direct-writer product — see our page on professions direct writers cannot cover for the mechanics. For a sole practitioner, this means the only realistic route to market is a broker with access to the qualifying insurer panel.
Third, the underwriting itself is more sensitive at the sole practitioner end. Insurers look closely at supervision, file management, cyber controls, the mix of work, the proportion of conveyancing (where the SRA MTC exposure is highest per pound of fee income), and any past claims or notifications. A well-presented submission is placeable in the normal course. A thin or late submission is a much harder conversation.
The SRA Indemnity Insurance Rules require every SRA-regulated firm to hold qualifying insurance that complies with the Minimum Terms and Conditions. The MTC are set out at Appendix 1 of the Rules. The obligations that matter most for a sole practitioner are as follows.
Clause 1.1 of the MTC sets the minimum limit of indemnity at £2 million any one claim for a partnership or sole practice, and £3 million any one claim for a recognised body constituted as an LLP or limited company. The choice of structure therefore drives the minimum limit — an incorporated single-director practice sits at £3 million, an unincorporated sole practice at £2 million. The limit applies to each and every claim, not on aggregate, which is one reason solicitor PI premiums per £1 million of limit are typically higher than for professions such as architects or engineers, whose regulatory minima commonly work on an aggregate.
Firms are free to purchase excess-layer cover above the minimum — commonly known as "top-up" — and many do. The excess layer sits outside the MTC and is placed on ordinary commercial terms.
The MTC requires the policy to respond to all civil liabilities arising from the firm's practice, with no retroactive date. A sole practitioner cannot restrict past cover by moving insurer — the incoming policy picks up prior liabilities. Protective for clients, but a firm cannot buy its way out of a legacy claims history simply by switching at renewal.
Clause 2.5 of the MTC deals with related claims. The wording aggregates claims arising from "one act or omission", "one series of related acts or omissions", "the same act or omission in a series of related matters or transactions", or "similar acts or omissions in a series of related matters or transactions". The interpretation of "matters or transactions" is one of the most litigated points in solicitor PI — the Supreme Court's decision in AIG Europe Ltd v Woodman (2017) and the earlier line of authority including Lloyds TSB v Baines Jewellery are the touchstones. For a sole practitioner exposed to similar transactions — conveyancing plots on the same development, a series of investment schemes — aggregation determines whether one limit responds or many. Our page on the aggregation clause and "matters or transactions" case law covers this in more depth.
The MTC requires defence costs to be paid in addition to the primary limit of indemnity, and requires cover to respond notwithstanding the dishonesty of any principal, subject to specified carve-outs. For a sole practitioner, the fraud provisions carry particular weight because the firm has no non-dishonest principal — the MTC nonetheless requires the innocent client to be indemnified within the clause framework.
Every SRA-regulated firm's PI renewal falls on 1 October, unless the firm has been granted an extended policy period. This creates a market-wide submission peak in July, August and September, with the qualifying insurers processing the majority of the profession's renewals in a compressed window.
For a sole practitioner, the timing pressure is amplified by the absence of a partnership to share the workload. A renewal submission — proposal form, claims record, complaints record, cyber controls narrative, work-type split, fee-earner CVs, financial position — is not a single afternoon's work. Leaving it to late September, alongside client work, is where sole practitioners come unstuck.
The practical guidance is straightforward. Start three months out — early July for a 1 October expiry. Populate the proposal form once, in a form that can be issued to more than one insurer without rework. Sit with the past year's complaints and notifications and have a considered narrative on each. If conveyancing is part of the mix, be ready to evidence source-of-funds procedures, ID checks, cyber controls and response to APP fraud and vendor-impersonation risk — this is where the qualifying insurers focus.
Expect detailed insurer enquiry on cyber security posture, response to any dear-CEO or dear-purchaser style fraud attempt, the mix of purchase-money and remortgage conveyancing, any file audit or SRA visit findings, and the arrangements the firm has in place for supervision and cover during absence — a specific point of underwriting interest for a sole practitioner.
The SRA MTC requires that on cessation, the last qualifying insurer provides six years of run-off cover to the closed firm. This obligation sits within the participating insurer regime and is one reason the qualifying insurer commitment is not simply a twelve-month subscription.
For a sole practitioner, run-off is normally the single largest financial exposure at end of career. Retirement, career change or a move to employed practice all trigger the obligation, unless there is a successor practice that assumes the liabilities — in which case the successor's MTC policy responds and no separate run-off is bought.
The commercial pricing of run-off is set by the participating insurer's rate card. As a market indication, run-off premiums for solicitor firms commonly fall in the range of two to three times the last annual premium for the full six-year period, though the actual figure depends on the firm's work mix, claims history and the insurer's rating basis. Some insurers permit the premium to be spread over the six years; others require a single up-front payment on cessation. A claims-active recent history or heavy conveyancing exposure moves the multiplier upward.
The planning implication is significant. A sole practitioner intending to retire in three years should already be discussing the run-off basis with the incumbent insurer — whether the multiplier is fixed, whether the premium can be spread, and whether the firm's structure permits a successor practice arrangement that would remove the run-off obligation from the closing firm. Our page on the six-year run-off obligation works through the mechanics.
Solicitors regulated by the Law Society of Scotland are not covered by the SRA MTC. Scottish solicitor PI is arranged through the Law Society of Scotland Master Policy, administered by Lockton and placed with a defined panel of insurers on a collective basis. Direct placement of Scottish solicitor PI is not available — a Scottish sole practitioner is covered by the Master Policy as a matter of professional membership, not by an individually arranged MTC policy. Our page on the Law Society of Scotland Master Policy covers the top-up layer, cessation run-off, and cross-border moves.
Apex Insurance Brokers Limited places solicitor PI across the qualifying insurer market for firms of every size, including sole practices and two- and three-partner firms. The firm is directly authorised by the Financial Conduct Authority (firm reference number 724952) and is not restricted to a scheme with a partner minimum.
The service is director-led. Matthew Bartlett — SMF3, SMF16 and SMF17 approved — is the named broker on the account. Sole practitioners speak to the same person at submission, renewal, claim notification and end-of-practice run-off.
The submission is prepared with the practitioner. The proposal form is completed once, cleanly, and issued to the qualifying insurers whose current appetite aligns with the firm's work mix and history. The claims and complaints record is presented with a considered narrative rather than a bare list.
Beyond the placement, Apex publishes the sector-mechanics reference material sole practitioners need — the aggregation case law, the run-off multipliers, the successor practice question, and the interaction with the SRA's adequate and appropriate insurance guidance. Our complete guide to solicitors' PI insurance and our reference on the SRA MTC in detail sit alongside this page.
Yes. Every SRA-regulated sole practitioner in England and Wales is required to hold qualifying insurance on the MTC, and cover is available across the participating insurer market. The placement route for a sole practitioner is a broker with access to the qualifying insurer panel — direct writers do not underwrite solicitor PI, and some specialist scheme brokers set partner minimums that exclude sole practices from their facility.
The premium is driven by gross fees, mix of work by discipline, claims and notifications history over the past six years, cyber and supervision posture, and the limit of indemnity purchased. Firms with a material conveyancing exposure sit at a higher rate per pound of fee than firms confined to private client, employment or commercial advisory work. Any figure quoted without reference to those drivers should be treated with caution — the qualifying insurers rate each firm individually and the range across the market for a given firm size is wide.
The SRA MTC sets the minimum limit of indemnity at £2 million any one claim for a sole practice or partnership, and £3 million any one claim for a recognised body constituted as an LLP or a limited company. The choice of firm structure therefore determines the minimum. Firms can, and often do, purchase excess-layer cover above the MTC minimum.
Yes, unless there is a successor practice that assumes the closed firm's liabilities. The SRA MTC requires six years of run-off cover from the last qualifying insurer, and the run-off premium is normally payable on cessation — either as a single up-front payment or, where the insurer permits, spread over the six-year period. Planning for this obligation is part of any retirement or succession conversation and should start well before the cessation date.
Some specialist solicitor PI schemes operate a partner minimum — commonly four principals — as a rule of their panel facility. This is a commercial choice by the broker and by the insurer providing the scheme paper, and it excludes sole practices and two- and three-partner firms from that particular route to market. It is not a comment on the underlying insurability of the smaller firm. For firms below a scheme's partner minimum, an individually placed submission across the qualifying insurer market is the alternative.
Direct writers — the insurers that offer PI directly to accountants, consultants and other professions — do not underwrite solicitor PI. The SRA MTC contains cover requirements that fall outside a standard direct-writer product, and solicitors are one of the professions that a direct writer cannot cover. Our page on professions direct writers cannot cover sets out the mechanics of that exclusion. Apex is a broker with access to the qualifying insurer market and places solicitor PI on MTC-compliant paper, including for sole practices and small partnerships.
