Automatic reinstatement of limit clauses in PI insurance

Reviewed by Matthew Bartlett, Director · Last reviewed 01 July 2026

An automatic reinstatement of limit clause is a professional indemnity (PI) policy provision that restores the annual aggregate limit after a claim has been paid, so a firm keeps meaningful cover for the balance of the policy year. It is often the difference between a policy that pays a large loss and a policy that also survives to pay the next one.

Aggregate limits and why reinstatement matters

Most UK PI policies are written on an annual aggregate basis. The limit of indemnity — say £5m — is the maximum the insurer will pay for all claims made during the policy period, not per claim. Once claims and defence costs erode that aggregate, the cover is spent. A firm that suffers two significant matters in the same year can find itself uninsured for the second, even though the policy is still in force.

A reinstatement clause tops up the aggregate. Typical policy wording reads: "the aggregate limit of indemnity shall be automatically reinstated one time upon payment of a claim, subject to the terms and conditions of this policy." Mechanics vary by insurer, but the principle is the same — after a paid claim, a fresh limit becomes available for later matters notified in the same period.

The main structures on offer

• One automatic reinstatement. The most common commercial-market position. The aggregate is refreshed once during the year, giving effectively two full limits — though never more than one available at a time.
• Unlimited reinstatements. Rare and generally expensive, occasionally seen on very large programmes or on excess layers. The aggregate is topped up each time it is eroded.
• Restoration on payment. The limit is only refreshed once a specific claim has been settled and paid. That matters for firms with slow-moving matters where a claim may be notified but unpaid at the point a second issue arises.
• Costs-inclusive versus costs-in-addition. A reinstatement is more valuable where defence costs sit outside the limit, because the aggregate is not eroded by the costs of the first claim before the second is notified.

Cost and underwriting

Reinstatement is usually rated. Some insurers include one automatic reinstatement within the base premium for standard commercial risks; others charge an additional premium, particularly where the firm's claims experience or sector is regarded as higher-frequency. Underwriters look at discipline profile, fee income, historic claims record, and retention level before agreeing to reinstate. On distressed placements, reinstatement is often the first feature to fall away.

The Minimum Terms and Conditions position

Under the Solicitors Regulation Authority (SRA) Minimum Terms and Conditions, the aggregate limit structure is prescribed — practices with corporate structures have an aggregate limit and unincorporated practices have an each-and-every-claim limit. Any reinstatement above the mandatory minimum is a matter for the individual policy and the negotiated wording, not the MTC itself. Firms that want reinstated cover above the minimum need to buy top-up layers with the feature specifically negotiated. The Law Society of Scotland Master Policy sits under a different arrangement, and reinstatement questions there are handled through the Master Policy broker.

ICOBS 6 requires that customers are given clear information about the essential features of a policy before contract, and the aggregate structure — including whether and how it reinstates — is exactly the sort of feature that needs to be presented fairly.

Worked example — architectural firm, £5m aggregate with one reinstatement

The following is an illustrative worked example only, not a quotation for any specific firm.

An architectural practice buys a PI policy with a £5m aggregate limit and one automatic reinstatement. In April, a claim arising from a design dispute is settled at £4m. In November, a second unrelated claim is notified and eventually settled at £3.5m.

Without a reinstatement, the aggregate after April would stand at £1m remaining. The November claim of £3.5m would breach the aggregate by £2.5m — an uninsured exposure the firm and its principals would have to fund from balance-sheet reserves.

With one automatic reinstatement, the aggregate is refreshed to the full £5m once the April claim is paid. The November claim of £3.5m sits comfortably within the refreshed limit, and the firm remains fully insured. The reinstatement, in this example, prevents a £2.5m uninsured loss.

Practical value and the broker's role

Reinstatement matters most for firms in higher-claim-frequency areas — busy conveyancing practices, high-volume architectural or engineering firms, IFAs advising on complex products, and any professional business where a single event might generate more than one notification. It also matters where the aggregate limit sits close to the value of a single significant instruction.

At renewal, Apex negotiates the reinstatement position as part of the placement rather than accepting the standard wording without challenge. That includes checking whether the reinstatement is one-time or unlimited, whether it operates on payment or on notification, whether defence costs are inside or outside the aggregate, and whether any additional premium is proportionate to the exposure. Apex documents the position in the demands and needs statement so the client can see what has been arranged and why.
