Solicitors Professional Indemnity Insurance — The Complete UK Guide 2026

If you run an SRA-regulated firm, your professional indemnity insurance is not optional, it is not generic, and the rules around it are stricter than most other UK professions. This guide pulls together everything you need to know to renew well, switch brokers without disruption, or set up cover for the first time.

It is written for partners, sole practitioners, COFAs, COLPs, and practice managers who handle the renewal each year and want to understand the regulatory framework, the cost drivers, and the negotiating levers — not just receive a number from a broker.

TL;DR — the headline points

If you already know the basics and are here for one specific topic, the sections below are designed to be read in any order.

What SRA-regulated firms must have

The Solicitors Regulation Authority requires every firm it authorises to hold qualifying insurance that meets the Minimum Terms and Conditions. The MTC is a published statutory framework, not a guideline — its terms are mandatory and override any narrower wording an insurer might prefer to write.

The key requirements are:

Indemnity limit. £2 million each-and-every-claim for sole practitioners and partnerships. £3 million each-and-every-claim for LLPs and other incorporated practices (technically: relevant recognised bodies and relevant licensed bodies). The "each-and-every-claim" basis is fundamental — it means every separate claim against the firm attracts the full limit, not a shared annual pool. A firm that suffers three unrelated negligence claims in the same year gets three full limits, not one.

Approved insurer. The cover must be placed with a Participating Insurer under the Participating Insurers Agreement. (The legacy term was "Qualifying Insurer"; the substantive framework is the same.) The composition of the panel changes annually. The live list is published by the SRA at sra.org.uk/solicitors/resources/professional-indemnity/qualifying-insurers/ — the URL still uses the legacy slug.

Civil liability cover. The policy must cover civil liability arising from your practice, with no carve-out for negligence, breach of trust, breach of duty, or breach of warranty.

Defence and mitigation costs. Defence costs cover (which includes mitigating circumstances that might give rise to a claim) is payable in addition to the limit with no monetary cap. The excess does not apply to defence costs.

Aggregation provisions. The MTC defines when multiple matters can be treated as a single claim (and therefore share a single limit and excess) versus when they are treated separately. The application of aggregation can materially affect outcomes; recent case law has created some uncertainty around how aggregation operates in cases involving dishonest individuals within a firm.

Run-off cover. When a firm ceases to practise, six years of run-off must be maintained at the MTC minimum limit (clauses 5.3 / 5.4 of the MTC). The cover cannot be cancelled — the insurer must continue to provide cover for the full six years even if the firm fails to pay the run-off premium, and the insurer must pay claimants directly if the insured firm does not.

Successor practice cover. If your firm merges with or is acquired by another, the surviving practice generally inherits responsibility for run-off on the prior practice. This catches a lot of firms by surprise during M&A — the buyer's insurer may load the premium to absorb the seller's exposure.

Excess. The excess sits between the insurer and the insured firm. Under the MTC there is no monetary cap on the excess level, but it cannot apply to defence costs and cannot erode the limit of indemnity. If the insured firm fails to pay an excess within 30 days, the insurer must pay the claimant directly.

The MTC also requires specific terms around when cover applies, how claims are notified, what counts as a "claim" versus a "circumstance," and what discretion the insurer has.

Why solicitors PI is structured differently from other professions

Other regulated professions in the UK — architects, accountants, surveyors, financial advisers, engineers — all have professional indemnity requirements, but each is set by its own regulator with its own logic.

Architects (regulated by the ARB) need £250,000 each-and-every-claim minimum, on a civil liability basis. Exceptions are permitted for cladding and fire-safety matters, asbestos, and pollution, which can be written on aggregate.

Surveyors under RICS have a banded minimum from £250,000 up to £1 million depending on fee income — currently (effective 1 July 2025) £250,000 for firms with fee income below £100,000, £500,000 between £100,000 and £200,000, and £1,000,000 above £200,000.

Accountants under ICAEW or ACCA work to graduated limits based on fee income, typically expressed as a multiple of gross fee income.

Financial advisers under the FCA work to the cover requirements in IPRU(INV) Chapter 13. Current minimums for personal investment firms are a single-claim limit equivalent to at least €1,300,380, and an aggregate limit of the higher of €1,924,560 or 10% of annual income (capped at €30 million).

Solicitors stand apart for three reasons:

Higher minimum limits. £2 million or £3 million is materially above almost all other UK profession minimums. These limits reflect the SRA's view that the severity of professional negligence claims against solicitors — particularly in conveyancing, deadline-driven litigation, and trust drafting — warrants a higher floor than most other UK professions.

Statutory each-and-every-claim basis. The SRA does not permit annual aggregate limits to dilute cover. This is a strong protection for clients but it forces a particular risk model on insurers, who must price for tail risk rather than average expected loss.

Embedded run-off requirement. Most other professions allow firms to choose whether to buy run-off on closure (with regulatory pressure to do so). The SRA makes it mandatory, prescribes the length, and makes the cover non-cancellable.

The practical consequence: brokers and insurers who do not specialise in solicitors PI often get the technical detail wrong. Common errors include selling cover described as "aggregate" (regulatorily impossible under the MTC), failing to disclose the run-off implications of a structural change, or quoting against a non-Participating Insurer (which would leave the firm in breach of the Indemnity Insurance Rules).

Common claim types and how they arise

Conveyancing

Conveyancing is consistently identified by the SRA and the Law Society as one of the largest sources of claims by both volume and value. The common patterns:

Conveyancing-heavy firms typically pay higher premiums for this reason. Risk management measures — strong file-opening protocols, mandatory anti-fraud checks, partner-level oversight on high-value transactions — directly affect both claim frequency and premium.

Litigation — limitation and deadline claims

Missed limitation periods remain a steady source of claims. The Limitation Act 1980 has dozens of distinct time limits depending on the cause of action.

These claims are often individually severe because the limitation period is a complete bar — the client loses the underlying claim entirely and the lost-chance value is the measure of the claim against the firm.

Trust, estate, and probate

Drafting errors in wills and trusts are a steady source of medium-severity claims:

Commercial and corporate work

Client account and SRA Accounts Rules

Strictly, breaches of the SRA Accounts Rules are not always covered by PI. Misuse of client money is generally excluded under most policies. Claims arising from genuine error in accounting (rather than dishonesty) may attract cover.

Post-six-year claims and SIF

Post six-year claims fall outside mandatory run-off and are covered by the Solicitors Indemnity Fund (SIF), which the SRA took direct control of in October 2023. After years of uncertainty about SIF's closure, the SRA confirmed it will continue to provide indemnity for late claims as part of its consumer protection arrangements. Lester Aldridge has been appointed by the SRA to manage claims on SIF's behalf, and there is no additional cost to former principals.

What actually drives your premium

Insurers price solicitors PI on a combination of objective factors and underwriter judgement. The main drivers, in approximate order of weight:

Gross fee income. The primary rating factor. Premium is typically expressed as a percentage of fee income, with the specific percentage varying materially by firm size, work mix, and claims history.

Work mix. Conveyancing, particularly in volume, is the most heavily-loaded work type because of the claims experience described above. Commercial work, immigration, employment, family, and will-writing are typically rated more favourably. Litigation rates sit in the middle and depend heavily on the type. Some insurers will not write firms with conveyancing above a threshold percentage of fee income.

Claims history. Insurers typically look back over five to six years when underwriting, though some review the full claims history of the firm. A clean record over the look-back window gets the firm the best terms available for its size and work mix. Recent severe claims can put the firm into the assigned-risks part of the market with materially higher premiums. The age of the claim matters — older claims carry less weight.

Number of fee-earners and partner ratio. Insurers want to understand supervision. A firm with one partner supervising fifteen fee-earners is rated differently from a firm with five partners and ten fee-earners. The fee-earner-to-partner ratio is a proxy for risk control.

Regulatory history. Any prior SRA investigation, intervention, or finding affects the underwriting decision and the price. Routine SRA monitoring visits are not material; specific findings are.

Firm structure changes. A merger, demerger, partner exit, or change in legal entity within the look-back window will affect the underwriter's view. The successor practice rules in the MTC can create unexpected exposures.

Excess level. Higher excess reduces premium. The MTC does not cap the excess, but the excess cannot apply to defence costs and cannot erode the limit of indemnity. Firms with strong cash positions sometimes opt for higher excesses to manage premium.

Cover limit above the minimum. Most firms buy above the MTC minimum, particularly for work where a single claim could exceed £2-3 million. The cost of additional layers is typically much cheaper per million than the primary layer, because the probability of a claim breaching the higher attachment point is lower.

Risk management. Firms with documented risk procedures, COLP / COFA arrangements, formal file-opening protocols, second-partner sign-off on high-value matters, and continuing professional development structures attract better terms. This is not a tick-box exercise — insurers will look for evidence in their underwriting process.

Office locations. Geography occasionally affects premium, particularly for firms with multiple offices in different jurisdictions or those operating cross-border.

How to choose a broker for solicitors PI

Choosing a broker for solicitors PI is materially different from choosing a broker for other commercial lines. There are currently 52 Participating Insurers on the SRA's published list for 2025/26 — the highest number ever recorded, double the 26 at the start of the 2019 hard market. Brokers vary widely in how many of these they can access.

The five things that matter:

1. Whole-of-market access. A broker that only accesses a subset of Participating Insurers cannot deliver the best terms on the market — they can only deliver the best from their available panel. Ask explicitly which Participating Insurers your broker can approach on your behalf. The best answer is "all of them," and the next-best is a strong relationship with the four or five insurers most likely to write your specific risk.

2. FCA authorisation. Verifiable on the FCA Register at register.fca.org.uk. The firm reference number lets you check the authorisation status, scope of permissions, and any regulatory history. Apex Insurance Brokers Limited is FCA-authorised under FRN 724952.

3. Specialism in solicitors PI. The MTC is technically detailed and the Participating Insurer market behaves differently from general commercial PI. A broker that handles a steady volume of solicitor placements knows the underwriters personally, knows which insurer is currently appetite-positive for which work mix, and knows how to present a firm's risk in the way each underwriter likes to see. Ask how many solicitor placements they handle annually.

4. Named broker continuity. PI is a relationship-driven product. A named broker who handles your renewal each year, knows your firm's history, and has a track record with your incumbent insurer will deliver materially better outcomes than a generic call-centre relationship. Ask who specifically will handle your account.

5. Claims advocacy. Brokers vary enormously in how they handle the moment when a claim or circumstance arises. The best brokers handle the insurer interaction directly, ensure the notification is in the form the insurer needs, advocate on coverage decisions, and stand between the firm and the loss adjuster. This is when you find out whether your broker is a transaction shop or a relationship.

A note on tied brokers: some firms are approached by brokers tied to a single Participating Insurer (or a small handful). These can be perfectly adequate for firms whose risk profile matches the tied insurer's appetite. But they are not whole-of-market and will not deliver the best terms across the panel.

Renewal — what to do and when

Renewal is where the difference between a well-run process and a rushed one shows up in the premium.

The "1 October common renewal date" was formally abandoned by the SRA in 2014, but around 75% of firms still renew on 1 October as a market convention. Most market commentary still refers to "1 April" and "1 October" as the two main renewal seasons, with 1 October by far the busier.

We recommend starting your renewal process well in advance — typically several months before the renewal date — so that there is room to gather information cleanly, brief the broker, approach the market, and negotiate variations rather than accepting take-it-or-leave-it terms because there is no time to switch.

The principle: a rushed renewal forces the broker to approach a limited set of insurers quickly. Underwriters who have time to engage properly tend to offer better terms. There is also room to negotiate excess levels, cover limits, and other variations when the timetable allows it.

Special situations

Sole practitioners

Sole practitioners face a particular set of structural pressures. The MTC minimum (£2 million each-and-every-claim) is the same as for partnerships, but with no partners to spread either the work supervision or the cost. Common reasons sole practitioner premiums are positioned higher as a percentage of fee income include:

Sole practitioners considering retirement should plan run-off cover well in advance, as the cost is typically several multiples of the final annual premium and payable on closure.

Mergers, acquisitions, and demergers

The successor practice rules in the MTC are some of the most complex provisions in the regulatory framework. The default position is that the surviving practice inherits the predecessor's claims exposure, including the obligation to maintain run-off cover for the predecessor's prior business.

In practice this means:

The financial impact varies. A clean-record acquisition of a clean-record firm typically produces a combined premium close to the sum of the two prior premiums. An acquisition where one firm has a claims history can produce a step-change in the combined premium that should be factored into the deal economics.

Firm closure and run-off

Closing a firm — whether through retirement, sale, or merger — triggers the run-off obligation. The MTC requires six years of run-off cover at the MTC minimum limits, with no cancellation right and no requirement on the firm to pay the premium for cover to continue (the insurer remains on risk regardless). This is one of the largest predictable costs in the lifecycle of a law firm.

Practical guidance:

Partners retiring without firm closure

When an individual partner retires but the firm continues, the firm's ongoing PI provides forward cover and the past acts of the retiring partner remain covered under the firm's policy and any subsequent renewal — provided the firm continues to exist. The retiring partner does not need to arrange personal run-off cover unless they continue to practise (in which case they need new cover).

The SRA-approved (Participating) insurers

The SRA publishes the list of Participating Insurers annually. The composition changes year to year as insurers enter and leave the market. For the 2025/26 indemnity period there are 52 Participating Insurers listed — the highest number ever recorded, and double the 26 at the start of the 2019 hard market. The current list is published at sra.org.uk/solicitors/resources/professional-indemnity/qualifying-insurers/.

A broker with whole-of-market access can approach any insurer on the current list. The right choice for any particular firm depends on the firm's size, work mix, claims history, and the current appetite of each insurer.

Important: PI cover written by an insurer not on the Participating Insurer list does not qualify under the SRA Indemnity Insurance Rules. Any firm placed with a non-Participating Insurer would be in breach of the rules. Confirm before binding that your insurer is on the current Participating list.

Frequently asked questions

What is the minimum PI cover an SRA-regulated firm must hold?

£2 million each-and-every-claim for sole practitioners and partnerships, and £3 million each-and-every-claim for LLPs and other incorporated practices (technically: relevant recognised bodies and relevant licensed bodies). These limits are statutory under the SRA Minimum Terms and Conditions.

Is solicitors PI cover written on an aggregate basis?

No. The SRA Minimum Terms and Conditions require cover on an each-and-every-claim basis. Each separate claim attracts the full minimum limit. There is no shared annual ceiling. Any policy written on an aggregate basis does not meet the SRA's requirements.

How long is the run-off cover requirement on firm closure?

Six years from the date the firm ceases to practise (clauses 5.3 / 5.4 of the MTC). The cover must be maintained at the MTC minimum limit and cannot be cancelled. The insurer remains on risk for the full six years even where the firm does not pay the run-off premium.

Can I switch insurers mid-year?

You cannot cancel a Participating Insurer policy mid-year because the MTC prevents cancellation. You can switch at renewal each year. Most firms review the market every one to three years; reviewing every renewal is not necessary but can be useful when there has been a structural change in the firm.

Does run-off cover apply if I retire as a sole practitioner?

Yes. A sole practitioner ceasing to practise triggers the run-off requirement on the same terms as a firm closure. Six years at MTC minimum limit. The cost should be planned well before retirement.

What happens to PI when two firms merge?

The surviving firm generally inherits responsibility for the prior business of the acquired firm, including the obligation to maintain run-off cover for the predecessor's exposure. The acquirer's PI insurer typically rates the acquired firm's claims history into the combined premium. Both firms' PI history should be fully disclosed during the merger process.

Do I need to notify my insurer of a claim or just a complaint?

You must notify your insurer of any circumstance that might give rise to a claim — not only crystallised claims. The MTC defines "circumstance" broadly. Failure to notify a circumstance within the policy period can compromise cover when the claim later emerges. When in doubt, notify. Notification is not an admission of liability.

Are conveyancing firms harder to insure?

Conveyancing-heavy firms typically pay higher premiums as a percentage of fee income because conveyancing claims account for a substantial share of solicitors PI claims by both number and value. Some insurers will not write firms with conveyancing above a threshold percentage of fee income; others have specific appetite for the segment. A broker with whole-of-market access can identify which insurers are currently appetite-positive for conveyancing-heavy firms.

Can I just buy the SRA minimum or should I buy more?

Most firms buy above the minimum. Conveyancing transactions, commercial work, and high-value litigation can all generate individual claims well above £2-3 million. Additional layers above the primary limit are typically priced at a discount per million compared to the primary cover. The right level for any firm is a function of the work being done and the firm's risk appetite — your broker should walk you through the cost-benefit at renewal.

What happens to claims notified after the six-year run-off period?

Late claims notified after the mandatory six-year run-off period are covered by the Solicitors Indemnity Fund (SIF). The SRA took direct control of SIF in October 2023, having confirmed in 2023 that it would continue to provide post-six-year indemnity rather than close SIF. There is no additional cost to former principals. Lester Aldridge manages claims on SIF's behalf.
