PI cover sizing · Surveyor

How much PI insurance cover does a surveyor need?

Reviewed by Matthew Bartlett, Director, Apex Insurance Brokers Limited (FCA FRN 724952) · Published 15 July 2026

The RICS turnover-band PI scale sets a floor by fee income: firms up to £100k need £250k cover; firms over £200k need £500k; firms over £500k need £1m. Actual placements are often significantly higher.

The regulatory floor: RICS Rules of Conduct Rule 9

Regulatory floor: turnover-band scale (from £250k to £1m+).

But the regulatory floor is a floor, not a target. Actual placements are usually materially higher.

What drives the number above the floor

Valuation-only firms often carry £2m-£5m; residential surveying may need £1m+.
Building-safety exposure (BSA 2022) elevates limits for surveyors advising on higher-risk buildings.
Lender-panel work often has minimum limits set by the lender.
Chartered firms should also consider aggregate limits carefully.

Typical placement bands

Small practice: floor to 2× floor.

Medium practice: 2-5× floor.

Larger practice: 5×+ floor, guided by claim exposure and turnover.

Bespoke risks (larger transactions, complex work): bespoke sizing with the broker.

The Apex approach

We size PI limits by looking at three factors: regulatory floor, worst-case single claim exposure, and aggregation risk across the book of work.

For most firms, that produces a limit materially above the regulatory floor.

The right limit balances cost against catastrophe protection — we work through this with you at placement.

Frequently asked

What's the RICS Rules of Conduct Rule 9 minimum for a surveyor?

turnover-band scale (from £250k to £1m+). See RICS Rules of Conduct Rule 9 guidance for the exact wording.

Is the regulatory minimum enough?

For most firms, no. It's a floor — actual placements typically sit materially higher based on claim exposure.

How is my premium calculated?

Insurers price on turnover, work profile, claim history, cover level and territorial exposure. Higher limits cost more, but not proportionally.

Does aggregation matter?

Yes. If cover is on an aggregate basis, multiple claims in one year draw down the same limit.

What about run-off?

Ceased practices need run-off cover in line with the regulator's requirement — typically 6 years for most professions.

Can we change limit mid-year?

Yes, via mid-term adjustment. Broker involvement to price and place the change.

How these figures are produced

This guide is built from Apex's own market data: the premiums insurers have actually quoted and charged on professional indemnity risks we have handled. Each night that data is aggregated into anonymised rate bands by profession, fee income and limit of indemnity. No client information is published — a band only appears where it contains at least five separate records, and unusually high premiums are excluded so a single atypical risk cannot distort the guide.

The range shown spans the typical spread of recent market outcomes for similar risks. Individual quotes can fall outside it in either direction. Figures exclude insurance premium tax at 12%.

This calculator is not a quote and is not an offer of insurance or advice. Your actual premium depends on full underwriting of your business, including your activities, claims record and insurer appetite at the time.
