Professional Indemnity Insurance for Chartered Building Surveyors
Reviewed by Matthew Bartlett, Director, Apex Insurance Brokers Limited · Last reviewed 2026-08-05
Why building surveyors need PI cover
Chartered building surveyors give opinions that clients rely on to make large financial decisions. A homebuyer commits to a purchase on the strength of a survey. A landlord budgets repairs from a condition report. A developer prices a scheme from a schedule of dilapidations. When that professional opinion is later alleged to be wrong, the claimed loss can dwarf your fee.
Professional indemnity insurance responds when a client (or sometimes a third party) alleges that your work was negligent, inaccurate or fell short of the reasonable standard of a competent surveyor, and that they suffered a financial loss as a result. It covers your legal defence costs and any damages or settlement you become liable to pay, subject to your policy terms and limit.
Is PI insurance mandatory for RICS surveyors?
Yes. Under the RICS Rules of Conduct and the associated professional indemnity insurance requirements, every RICS-regulated firm must hold PI cover that meets RICS minimum standards for as long as it carries out surveying work. This is not optional and RICS monitors compliance as part of firm regulation.
The key features RICS requires include:
- RICS-approved minimum wording. Your policy must be on terms that meet the RICS minimum policy wording, placed with an insurer that has agreed to it.
- A minimum limit of indemnity linked to fee income. RICS sets a sliding scale so that firms with higher turnover must carry a higher limit.
- Run-off cover. When a firm stops trading, RICS requires run-off cover to continue for a set period so past clients remain protected.
- Controls on excess and aggregation so that the cover is meaningful and not eroded by an unreasonably high self-insured amount.
Individual surveyors employed by a firm are usually covered under the firm's policy. If you practise independently, provide consultancy, or act as a sole practitioner or expert witness, you generally need your own PI policy in place.

Building surveying carries some of the most claim-prone exposures in the property professions, because so much of the work turns on inspection, judgement and forecasting. Common claim triggers include:
- Missed or under-reported defects. Damp, structural movement, timber decay, roof and drainage problems that a claimant argues should have been identified on inspection.
- Failure to advise on further investigation. Not flagging that a specialist report (structural engineer, damp, timber) was needed before purchase.
- Building survey vs. condition report scope disputes. A client alleging the report they received was less thorough than the service they believed they had bought.
- Valuation and reinstatement figures. Errors in reinstatement cost assessments for insurance, or in any valuation element, leading to under-insurance or loss.
- Schedules of dilapidations and condition. Disputes on party wall matters, dilapidations, or contract administration where the surveyor advises landlord or tenant.
- Project monitoring and defects certification on works the surveyor oversaw or signed off.
Because these claims often surface years after the work, PI is written on a claims-made basis: it responds to claims first made against you during the policy period, whenever the original work was carried out. That is why continuous cover and, eventually, run-off cover matter so much.
What limit of indemnity do you need?
Your minimum limit is driven by the RICS fee-income scale, but that floor is often lower than the exposure a single claim can create. The right limit reflects the value of the properties you survey, the type of clients you act for, and any contractual requirements imposed on you.
| Illustrative limit | Typically suits |
|---|---|
| £1m | Sole practitioners and small firms doing residential surveys of standard-value homes, where the RICS scale permits. |
| £2m | Firms with mixed residential and commercial work, higher-value properties, or clients who require a higher contractual minimum. |
| £5m+ | Firms handling commercial portfolios, high-value or complex buildings, project monitoring, or lender and institutional clients. |
These are generic illustrations, not a recommendation. Check your actual RICS minimum against your fee income, then consider whether contracts, lenders or the value of a single instruction justify a higher limit. It is worth confirming whether your limit is each and every claim or aggregate, and how defence costs sit against it.
Run-off cover: don't overlook it
When a firm closes, merges or a sole practitioner retires, claims can still arrive for years afterwards because of the claims-made structure. RICS requires run-off cover to remain in place for a defined period after a firm ceases surveying work. Building this into your planning early — before you wind down — avoids a scramble for cover at the point you have no ongoing income to fund it. We can help you understand what run-off will look like for your firm well ahead of time.
How Apex places PI for building surveyors
Apex Insurance Brokers is an FCA-authorised broker (FRN 724952) based in Bristol. We place professional indemnity cover for surveying practices with insurers who write on RICS-approved wording and who genuinely understand building-survey liability rather than treating it as generic professional risk.
Our approach is straightforward:
- We confirm your RICS minimum limit against your fee income and advise where a higher limit is prudent.
- We check the wording meets RICS minimum standards and flag any restrictions on activities such as valuations, project monitoring or expert witness work.
- We present the risk clearly to insurers, which matters on claims-made cover where disclosure and continuity are everything.
- We help you plan for run-off before you need it.

Common questions
Does my PI policy have to be on RICS wording?
To meet RICS requirements, yes — your cover must be on a policy that satisfies the RICS minimum policy wording and be placed with an insurer that has agreed to those terms. We only place surveying PI on compliant wording.
I'm an employed surveyor, do I need my own policy?
Usually not — you are normally covered under your firm's PI policy. You would need your own cover if you practise independently, do private consultancy or expert work outside the firm, or set up on your own.
What if a claim relates to a survey I did years ago?
PI is claims-made, so it responds to claims first notified during the current policy period regardless of when the work was done — provided you have maintained continuous cover. This is exactly why unbroken PI and, at the end, run-off cover are so important. Talk to us about continuity.
