Every practising Scottish solicitor is insured under the same policy, with the same insurers, on the same wording, placed by the same broker — and most do not own a copy of it.
The Master Policy is the collective primary professional indemnity insurance arrangement that the Law Society of Scotland procures on behalf of all practising Scottish solicitors. It is not a panel of qualifying insurers competing for individual firms’ business in the way the SRA Minimum Terms and Conditions work for English and Welsh solicitors. It is a single, collectively negotiated programme placed centrally — currently through Lockton as appointed broker — that gives every Scottish practitioner £2m primary cover per claim as a matter of regulation. This guide explains how it works, where it differs from the English model, what the Guarantee Fund adds on top, and how Apex helps Scottish firms decide what to buy above the floor.
In England and Wales, when a firm renews its PI cover it negotiates terms with one or more qualifying insurers, all of whom are bound to the SRA Minimum Terms and Conditions. Pricing varies, capacity varies, and a firm with a difficult claims record can find itself in the Assigned Risks Pool.
In Scotland, none of that happens at the primary layer. The Law Society of Scotland negotiates one programme for the whole profession. Every practising solicitor — whether sole practitioner, ten-partner conveyancing firm or a Magic Circle Scottish office — is automatically insured under that programme, provided the practising certificate is in good standing and the firm has paid its contribution. The programme renews on a single Society-wide date (1 November). Lockton, as the appointed broker, places the cover with a panel of insurers and is the day-to-day contact for claims under the Master Policy.
The primary limit is £2m per claim. Defence costs are in addition to the limit. There is a self-insured excess that varies by firm size and claims experience and is collected through the firm’s contribution. The wording is bespoke to the Master Policy — there is no comparable English document because there is no English Master Policy to compare it to.
What firms still need to think about, and where Apex’s role typically starts, is everything above and around that primary layer:
Mechanically, the Master Policy is a claims-made wording with Scottish law as the governing law. Trigger is the date a claim is first made against the insured solicitor and notified to the insurer.
Two features make it different from typical PI cover.
First, eligibility is collective. The insured under the Master Policy is, broadly, every practising Scottish solicitor as defined by the Solicitors (Scotland) Act 1980. A firm’s individual claim record affects its contribution and excess, but does not exclude it from cover. There is no Scottish equivalent of being declined by the market or pushed into an assigned risks pool.
Second, the Guarantee Fund sits alongside the Master Policy as a separate Society-administered fund under the 1980 Act. The Guarantee Fund compensates clients who suffer loss as a result of dishonesty by a Scottish solicitor — it does not respond to negligence, and it does not displace the Master Policy. Where dishonesty causes client loss, the Guarantee Fund is the relevant remedy; where negligence (or breach of trust falling short of dishonesty) causes loss, the Master Policy responds.
Top-up cover sits on a difference-in-conditions, difference-in-limits basis above the Master Policy. The excess layer wording is critical here: the buyer wants the excess layer to drop down to the Master Policy attachment, not to introduce new exclusions or notification conditions that fragment the programme. Apex’s standard approach is to insist on full follow-form to the Master Policy for the first excess layer wherever possible, and to negotiate any necessary carve-outs visibly rather than letting them sit buried in a generic London market wording.
A further structural feature is the way contributions are calculated. The Society uses a contribution-rating model that draws on firm size, fee income, work mix and individual claims history. A firm with a poor claims record pays a higher contribution and carries a higher self-insured excess but is not excluded from cover. The collective architecture absorbs the risk. By contrast, a poor claims record in the English market can result in non-renewal, placement in the Assigned Risks Pool, or withdrawal from regulated practice altogether. Whether the Scottish model is “better” is a debate for another day; what matters for the buyer is understanding which features are non-negotiable (you are in the pool) and which are negotiable (your contribution rating, your top-up cover, your run-off arrangements at closure).
Notification under the Master Policy is to Lockton. Notification under the excess layer is typically to the excess layer’s nominated agent. Firms must notify both on the same day; a circumstance reported only to the primary layer is not deemed reported to the excess layer.
The duty of fair presentation under section 3 of the Insurance Act 2015 applies to the placement of any top-up cover. The Master Policy itself is procured by the Society, not by the individual firm, but firms still owe disclosure duties around the contribution-rating exercise — and inaccurate disclosure on top-up renewal can trigger remedies under section 8 of the Insurance Act 2015.
Consider a six-partner Glasgow firm with a mix of commercial property and private client work. In 2024 they act on the £6m sale of a development site. A drafting error in the disposition fails to reserve a critical servitude over an access strip. The buyer completes, discovers the issue in 2026, and raises proceedings against the seller’s solicitors for £1.4m, being the diminution in value of the seller’s retained land plus expenses.
The firm notifies Lockton and its excess insurer the same day. The claim falls within the current Master Policy year. The Master Policy attaches first, paying up to its £2m primary limit. Because the claim resolves at £1.4m plus defence costs of £220,000, the £2m primary is sufficient to pay the indemnity element, and the excess layer is not drawn on. The firm’s self-insured contribution applies as the working excess.
Had the claim settled at £4m, the £2m Master Policy would have paid first, the £3m top-up purchased through Apex would have responded for the next £2m, and the firm would not have been out of pocket beyond its excess.
Apex’s view: the Master Policy’s collective architecture is a quietly excellent piece of regulation — it removes the worst features of the English qualifying insurer market, including the assigned risks pool. But it also lulls firms into under-buying above the primary. £2m is not enough for any firm doing commercial conveyancing. We routinely place £5m to £10m of top-up for mid-sized Scottish firms, and we model the underlying matters every year to justify the limit. Treat the Master Policy as the foundation, not the building.
