How much cover?

How Much PI Cover Does a Surveying Practice Need?

In short: RICS sets minimum professional indemnity requirements for regulated firms, scaled to the firm’s income and set out in its current requirements — but for most surveying practices the minimum is only the starting point. The right limit is driven by the work you do (valuation, building surveys, dilapidations, party wall), the limits your clients and lender panels require, and the worst credible claim your instructions could produce. Apex is an independent, FCA-authorised UK broker (FRN 724952) that places PI cover for surveying practices of all sizes.

This is the surveyors’ edition of our limit-sizing series, written for partners and directors setting the limit at renewal. For the broader picture of surveyors’ PI — what the cover does, what it excludes, how the market works — see our full surveyors’ PI guide.

The regulatory starting point: the RICS minimums

If your practice is regulated by RICS, you must carry professional indemnity insurance meeting RICS’s minimum requirements. Those requirements scale the minimum limit to the firm’s income, and they also deal with the basis of cover, permitted excesses and the terms the policy must meet. We deliberately do not quote the figures here: they are set out in RICS’s current requirements, they are revised from time to time, and the current documents — not a remembered number — should be your reference at every renewal.

Two things follow. First, compliance is checked against the rules in force now, so confirm the current thresholds each year with RICS or your broker. Second, and more importantly: the RICS minimum is a floor calculated from income bands. It is not an assessment of your firm’s actual exposure, and for many practices it bears little relationship to the size of claim their work could produce.

Why valuation work usually drives the limit

If your practice does Red Book valuation work, that work — not the RICS minimum — will usually set your limit. Two forces push it upwards.

The size of the asset, not the size of the fee. A negligent valuation claim is framed by reference to the lender’s or client’s loss on the property, which is anchored to the value of the asset. The fee for the valuation is irrelevant to the quantum. A practice valuing substantial commercial or development assets can face a credible single claim far larger than anything an income-scaled minimum contemplates.

Lender panel requirements. Lenders commonly specify a minimum PI limit — and often a basis of cover and maximum excess — as a condition of panel membership. Panel requirements routinely sit well above regulatory minimums, and the highest limit any panel or client terms require of you is your contractual floor. Firms are sometimes surprised, on reading their panel agreements properly, to find they have under-bought against their own contracts.

Different work, different claim profiles

Surveying is not one risk, and a sensible limit reflects the mix of work the practice actually does.

Building surveys. The classic exposure is the missed defect: something significant that a competent survey should have found. The claim is measured against the cost consequences for the buyer, so the value and condition of the buildings you survey frame the exposure.

Dilapidations. Schedules, diminution valuations and settlement advice at commercial lease end each carry their own negligence exposures, on both landlord and tenant instructions. We cover this in detail in our dilapidations PI page.

Party wall work. Statutory appointments bring their own duties and their own ways of going wrong — procedural missteps, award errors, disputes over damage. The sums are often smaller than valuation claims, but the frequency profile is different.

The exercise for renewal is to take each material strand of your workload and ask: what is the worst credible claim a single instruction could produce? To be clear, that is an illustrative framing, not a forecast — the point is to find the upper bound of your realistic single-claim exposure and to test your limit against it, rather than against an income band.

Policy mechanics that change what a limit is worth

Any-one-claim versus aggregate. An any-one-claim limit reinstates in full for each separate claim; an aggregate limit is a single pot for the year that every claim erodes. Two policies with the same headline figure are very different products, and client and panel terms often specify which basis they require. Check yours.

Defence costs in or out. If defence costs sit inside the limit, spend on lawyers and experts erodes what remains for the claim itself — and valuation and defect disputes are expert-heavy. A costs-inclusive limit buys less protection than the same figure with costs in addition, and should be sized accordingly.

The excess. A higher excess trims premium but is a real liability in a claims-made class where several claims can arrive in one year. Make sure the excess is one the practice could pay more than once, and check it does not breach any panel or client requirement.

When excess layers are the answer

Where a lender panel or a client contract requires a limit above your primary policy — or where your worst-credible-claim analysis points higher than your primary insurer will go — the usual solution is an excess layer stacked above the primary rather than a wholesale re-broke. Layering lets you meet a specific requirement efficiently and is standard practice for valuation-led firms. Our excess layer guide explains how attachment and terms work.

Run-off and past work

PI is claims-made: the policy answering a claim is the one in force when the claim is made, not when the survey was signed. That means today’s limit must be adequate for yesterday’s work, and it means retirement or closure needs run-off cover maintained afterwards — RICS’s requirements address run-off for regulated firms, and again the current documents state the detail. If your practice has shifted toward higher-value instructions, remember the reverse is also true: past lower-value work does not justify a low limit if a claim from it would be dwarfed by claims from what you do now.

How Apex approaches it

At renewal we check your compliance position against RICS’s current requirements, review panel agreements and client terms for contractual floors, work through the severity of your instruction mix, and price the structures — primary and layered — so you can see the cost of each option before deciding. The aim is a limit you chose on evidence, not one you inherited.

Frequently asked questions

Is the RICS minimum enough for my firm?

For some small practices doing lower-stakes work, it can be. For any firm doing Red Book valuations, lender work or surveys on higher-value property, it usually is not: the minimum is scaled to income, while claims are scaled to asset values and consequences. Treat the minimum as the compliance floor and size the real limit from your contracts and your worst credible claim.

A lender panel requires more cover than I hold. What now?

Either increase your programme to the required limit or add an excess layer that takes your total to the requirement — the layered route is often the more economical, particularly when only one panel drives the higher figure. Do not simply stay on the panel with non-compliant cover: that is a contractual breach that surfaces at the worst possible moment, when a claim arrives.

Where do I find the actual RICS figures?

In RICS’s current professional indemnity insurance requirements, published by RICS and updated periodically. Check the live documents at each renewal or ask your broker to confirm the position in force — quoting last year’s thresholds is a common and avoidable mistake.
