A single notified circumstance can move a renewal from a 10% increase to a 60% increase, or take an account off the market entirely — and the way the file is presented to underwriters matters as much as the file itself.
The renewal that follows a claim or notification is the renewal that tests the broker. Underwriters re-rate. New insurers ask hard questions. Existing insurers either lean in with a long-term view or use the notification as the cue to reduce participation. Retroactive dates become live points of negotiation. The market’s reluctance to novate prior-year cover means moving insurer carries hidden risks that buyers underestimate. This guide sets out what changes at renewal after a claim, how underwriters actually re-rate, and the broker techniques for managing a hard renewal without paying twice.
A notification or paid claim alters three things at renewal: the underwriter’s view of the risk, the wording the market will offer, and the price.
A notified circumstance that has not crystallised into a claim is treated very differently from a paid claim. A circumstance is forward-looking — underwriters discount it by their assessment of the likelihood of crystallisation, by the quantum at stake, and by how the firm has handled it. A paid claim is the fact. It is in the loss ratio, on the loss run, and on the renewal proposal. There is no discount.
The underwriter’s re-rating process draws on the firm’s loss history (typically five years), the nature of the notified matter or paid claim, the wider sector experience, and an assessment of remedial steps taken. A single GBP 50,000 settlement on a routine matter rarely moves the needle. A GBP 800,000 settlement on a project that the firm continues to undertake will. A circumstance involving allegations of dishonesty against a named partner will move the needle even if no money has been paid.
The wording also shifts. After a paid claim, underwriters often impose specific exclusions — for the particular client, project, transaction type, or activity. They may impose specific excesses on the affected category of work. They may push the retroactive date forward to exclude the period in which the matter arose. The firm trades broad cover for capacity.
Price is the most visible consequence but often the least important. A 50% premium increase on a GBP 25,000 premium is GBP 12,500 — a manageable number for most regulated firms. A retroactive date moved forward by three years on a GBP 5,000,000 limit can leave six- or seven-figure exposures uninsured. Buyers fixated on premium movement often miss the bigger structural changes happening in the wording.
The claims-made trigger and the retroactive date are the two mechanisms that determine which policy responds to a claim and which exposures remain insured.
In the UK regulated market, PI is written on a claims-made basis. The policy responds to claims first made — or circumstances first notified — during the policy period. The retroactive date determines how far back the policy reaches: it excludes claims arising from acts, errors or omissions before the retroactive date.
After a claim, two outcomes are common. Where the firm renews with the same insurer, the existing retroactive date is usually maintained. The notification is locked into the year of notification and the new policy responds to new matters. Where the firm moves to a new insurer, the new insurer will scrutinise the retroactive date carefully and may insist on a forward-moved retroactive date — excluding the period in which the notified matter arose. This is the single most dangerous outcome of a poorly-handled hard renewal.
The “no novation” practice in the PI market refers to insurers’ reluctance to take on a prior insurer’s accrued claims exposure. A new insurer takes on the future; the prior insurer keeps the past, including the notified circumstance and any subsequent claim arising from it. The firm is left with cover split across two insurers — the new one for future matters, the old one (or its successors in run-off) for the notified matter. This is workable, but it requires the firm to maintain a clear record of which insurer carries which exposure.
The Solicitors Regulation Authority Minimum Terms and Conditions of Professional Indemnity Insurance, at clause 1, require qualifying insurers of solicitors to provide a retroactive date no later than the start of the firm’s continuous PI cover with that insurer. The MTC effectively prohibits forward-movement of the retroactive date during a continuous renewal with the same qualifying insurer. There is no equivalent prescriptive protection for RICS, ARB, ICAEW or BIBA-regulated firms; retroactive date movement is a real risk for those sectors.
The Insurance Act 2015, section 3, governs disclosure at renewal. Every notified circumstance and every paid claim is a material circumstance. Non-disclosure exposes the firm to the remedies in section 8 — proportionate remedies for non-deliberate breach, avoidance for deliberate or reckless breach.
Consider an architects’ practice with a GBP 5,000,000 limit, paying GBP 32,000 of premium in 2024/25. In May 2025 the practice notifies a circumstance arising from a residential scheme — a cladding specification query. In December 2025 the matter crystallises into a claim and settles in March 2026 for GBP 420,000 plus GBP 110,000 defence costs.
The practice renews in October 2026. The expiring insurer offers renewal at GBP 58,000 premium with the retroactive date maintained, a GBP 75,000 specific excess on cladding-related claims for two years, and a category notification requirement for any further residential cladding matters. Two other markets quote: market A at GBP 51,000 with the retroactive date moved forward to 2024 (excluding the project on which the claim arose, but the matter is already notified to the prior insurer and locked there) and market B at GBP 49,000 with a more restrictive residential exclusion.
The practice’s broker recommends staying with the expiring insurer. The retroactive date is preserved, all prior exposures remain insured under the continuous coverage, and the specific excess on cladding falls off after two clean years. Market A’s lower premium hides the structural shift: the new retroactive date means any matter arising from work done before 2024 that surfaces in 2027 onwards would fall outside the new insurer’s cover and would only be picked up by the prior insurer if notified before that policy expired. Market B’s exclusion is too broad given the practice’s portfolio.
Net result: GBP 7,000 of premium savings on alternative quotes are forgone in favour of structural integrity. Three years later the next claim arises from a 2021 commercial project and is covered without dispute under the maintained retroactive date.
The hard renewal playbook:
Apex’s view: the renewal after a claim is the renewal where a specialist broker earns the year’s fee. We see the same scenarios repeatedly — buyers chasing premium, retroactive dates moving by stealth, exclusions creeping in that no-one explained at binding. The fix is process: long lead time, structured presentation, incumbent engagement before market-out, retroactive date as a non-negotiable. Firms that follow that sequence usually come out of a hard renewal in a stronger position than they expected. Firms that leave it late take what they are offered.
