Professional indemnity (PI) insurance for surveyors is not a single market. The cover a surveyor must hold, the wording it must contain, and the run-off period that follows the closure of a practice all depend on which professional body the surveyor is regulated by. The Royal Institution of Chartered Surveyors (RICS) is the dominant regulator in the UK surveying market, and its Minimum Terms and Conditions (MTC) are among the most prescriptive PI regimes in any professional sector. Other bodies — including the Faculty of Architects and Surveyors (FAS), the Chartered Association of Building Engineers (CABE), and various Construction Industry Council (CIC) member bodies — set their own, often lighter, requirements that reflect different member populations and different scopes of practice.
This article compares those regimes side by side as they are understood at the time of writing in May 2026. The aim is to help surveyors, practice principals and finance directors see where the requirements converge, where they diverge, and what that means when arranging or renewing a PI policy. The figures and rule positions cited here are drawn from publicly available material published by each body and are subject to periodic review — practitioners should verify the current position with their own regulator before relying on any specific figure.
What this comparison covers
The scope of this article is UK-regulated surveyors operating in England, Wales, Scotland and Northern Ireland whose professional body sets PI requirements as a condition of membership or regulated status. It looks at the published minimum cover position, the prescription of wording (including civil liability basis and aggregation), the required run-off period on cessation, and the availability of any assigned risks pool or equivalent safety net.
The comparison does not cover surveyors regulated outside the UK, nor does it cover contractual PI demands that may be placed on a surveyor by a third party — for example, lender panel requirements for residential valuation work, or PI clauses in development consultancy contracts. Those contractual demands frequently exceed a professional body's published minimum and are negotiated separately. The article also does not constitute regulatory or legal advice; it is a general comparison of publicly known positions intended to help readers frame the right questions with their broker.
Why the bodies set different requirements
The different shapes of these PI regimes are not a value judgement on the rigour of the bodies. They reflect different member populations, different risk profiles and different histories. RICS regulates a large and heterogeneous body of surveyors covering everything from residential valuation for mortgage lenders through to commercial agency, quantity surveying, building surveying, plant and machinery valuation and dispute resolution. Because RICS-regulated firms touch consumers, lenders and major commercial counterparties, the body has historically taken a prescriptive approach to PI cover — specifying not just a minimum limit but the wording, the treatment of defence costs, the aggregation rules and the run-off period.
Smaller bodies regulate narrower or differently shaped populations. FAS, for example, includes practitioners whose work overlaps with smaller-scale residential and architectural surveying. CABE represents building engineers and surveyors who may also be members of allied technical bodies. The lighter prescription that some of these bodies apply reflects the narrower exposure profile of their members, not a relaxation of professional standards. A surveyor choosing between routes to qualification — or a firm employing surveyors from multiple bodies — needs to understand each regime on its own terms.
Body 1: RICS
Who it applies to
RICS regulation applies to RICS-regulated firms and to individual RICS members where they are personally accountable for regulated work. Any firm in which more than 50% of principals are RICS members, or which holds itself out as an RICS-regulated firm, falls within the regime. This captures the great majority of UK surveying practices doing valuation, building surveying, quantity surveying and commercial work.
Minimum cover position
Under the MTC as understood at the time of writing in May 2026, the minimum limit of indemnity is set by reference to a firm's prior-year fee income. The publicly known position is that the floor for smaller firms is GBP 250,000 each and every claim, scaling upward through fee-income bands to higher minimum limits for larger practices. RICS publishes updated bandings periodically and practitioners should verify the current band that applies to their fee income directly with RICS. Whatever the band, the limit is described as "any one claim" rather than as an annual aggregate for firms below higher fee-income thresholds.
Aggregation rules
The MTC restricts the use of aggregate limits for firms below certain fee-income thresholds. For those firms, each-and-every-claim cover is required, meaning the policy limit resets for each separate claim rather than depleting over a policy year. Firms above the published thresholds may be permitted aggregate limits but typically with reinstatement provisions. The intention is to ensure that a single large claim does not exhaust the cover available to subsequent claimants.
Run-off cover
RICS requires six years of run-off cover from the cessation of a firm's regulated activity. The six-year period aligns broadly with the statutory limitation period for contractual claims in England and Wales, although tortious and latent damage claims can sit on longer timescales. Run-off must be on MTC terms throughout the six years.
Wording requirements
The MTC are prescriptive. Cover must be on a civil liability basis (rather than the narrower negligence-only wording sometimes seen in other sectors), defence costs must be treated in addition to the limit for firms below the relevant fee-income thresholds, and the policy must not contain exclusions that would conflict with the MTC list. RICS publishes the current MTC text and a list of approved insurers — practitioners should refer to that list when placing or renewing cover.
Assigned risks pool
RICS operates an Assigned Risks Pool (ARP) which provides PI cover for RICS-regulated firms that have been unable to obtain cover on the open market. The ARP is intended as a short-term safety net rather than a long-term placement, and firms in the ARP typically pay a higher premium and face conditions on continued use. The existence of the ARP is one of the distinguishing features of the RICS regime.
Critical compliance points
The practical compliance points that catch firms out tend to be the same year after year: confirming that the policy is on the current MTC version, confirming that defence costs are in addition where required, ensuring the limit matches the correct fee-income band, and securing run-off promptly on closure or merger. A change of legal entity — incorporation, conversion to an LLP, or a merger — is a common trigger for run-off questions and should be discussed with a broker in advance.
Body 2: FAS — Faculty of Architects and Surveyors
Who it applies to
The Faculty of Architects and Surveyors regulates a smaller community of architects and surveyors, including practitioners whose scope overlaps with residential and smaller-scale commercial surveying. Membership is independent of RICS, although some practitioners hold dual membership. FAS members operating in their professional capacity are expected to hold PI cover appropriate to that work.
Minimum cover position
Publicly available guidance from FAS sets a minimum PI requirement for members operating in private practice, with the figure calibrated to the smaller-scale practices that make up much of its membership. The published minimum is materially lower than the RICS floor in many cases, reflecting the narrower exposure profile. Practitioners should verify the current FAS-published minimum directly with the body, as the figure is subject to periodic review.
Aggregation rules
FAS does not impose the same prescriptive aggregation rules as RICS. Cover can typically be arranged on either an each-and-every-claim or an aggregate basis, subject to the practitioner's commercial judgement and any contractual requirements from clients. The lighter prescription reflects the differently shaped member population rather than a different view of the importance of PI cover itself.
Run-off cover
FAS guidance encourages members to maintain run-off cover on cessation, with a period commonly aligned to the six-year statutory limitation window. The body's published position is less prescriptive than the RICS MTC requirement, and practitioners should confirm the current expectation with FAS.
Wording requirements
FAS does not publish an equivalent of the RICS MTC. Members and their brokers have more discretion over policy wording, although civil liability cover is generally regarded as the appropriate basis for surveying work and is what most insurers in this segment offer as standard.
Critical compliance points
For FAS members, the practical points are to ensure that the policy genuinely matches the scope of work being undertaken — including any work that might fall under reserved areas where lender or contractual requirements apply — and to confirm run-off arrangements at the point of cessation. Members who also undertake work that would attract RICS scrutiny if they were RICS-regulated should consider whether to arrange cover that meets the higher RICS-style standard as a matter of prudence, even where it is not strictly required by FAS.
Body 3: Other bodies — CABE, CIOB-adjacent routes and CIC members
Who they apply to
The Chartered Association of Building Engineers (CABE) regulates building engineers and building surveyors. The Chartered Institute of Building (CIOB) primarily regulates construction managers and project professionals, some of whom undertake surveying-adjacent work. The Construction Industry Council (CIC) is an umbrella body whose member organisations include several with surveying overlap. Each body has its own published PI expectations for members in private practice.
Minimum cover position
The minimum cover positions across these bodies vary. CABE publishes guidance for members in private practice that sets a minimum limit appropriate to building surveying and building engineering work. CIOB members operating as principals are expected to hold appropriate PI cover but the body's prescription is generally lighter than the RICS MTC. CIC does not itself impose a uniform minimum across its member bodies; each constituent body sets its own. Practitioners should verify the current position with their specific body.
Aggregation rules
Across these bodies, aggregation tends to be a matter for the practitioner and broker to determine in light of the work undertaken and any contractual requirements. None of these regimes imposes the level of prescription found in the RICS MTC.
Run-off cover
A six-year run-off period is commonly recommended across the sector as it aligns with statutory limitation, but the requirement is generally expressed as guidance rather than as a mandatory MTC-style rule. Practitioners closing a practice should make a positive decision about run-off rather than assuming the obligation will be discharged automatically.
Wording requirements
There is no published MTC equivalent for these bodies. Cover is typically arranged on a civil liability basis with defence costs treated as the market norm for the relevant insurer rather than as a body-mandated requirement.
Critical compliance points
The single most important compliance point for surveyors regulated by these bodies is to recognise where their work crosses into reserved areas. A CABE-regulated building surveyor who undertakes a residential valuation for a mortgage lender will face the lender's own PI requirements, which often mirror the RICS MTC position regardless of the surveyor's professional body. Contractual PI demands from clients — particularly lenders, public-sector procurers and large developers — can effectively pull a non-RICS practitioner up to RICS-style cover. That is a commercial reality to plan for, not a regulatory failure of the smaller bodies.

Dimensions worth comparing
When comparing the regimes in practice, the dimensions that matter most are these:
- The minimum limit or floor. A higher published floor does not by itself mean better cover for a given firm — it means the regulator has chosen a higher baseline. A firm's actual cover need is driven by the work it does, the value of the assets it advises on, and the contracts it signs.
- Aggregation. Each-and-every-claim cover is more protective than an aggregate limit, but it is also more expensive. The MTC's prescriptive position for smaller RICS firms removes a commercial choice that practitioners regulated by other bodies retain.
- Run-off length. Six years aligns with statutory limitation but does not catch every long-tail latent damage claim. Practitioners with significant valuation or structural exposure may consider whether longer voluntary run-off is appropriate.
- MTC prescription level. The MTC removes wording risk in the RICS market because non-compliant wordings cannot be offered to RICS firms. The trade-off is that practitioners have less flexibility to negotiate exclusions or limit-of-liability mechanics.
- Defence costs treatment. Defence costs in addition to the limit are valuable in any sector, but particularly so where claims are technically complex. RICS prescribes the position for many firms; in other regimes it is a market norm to be checked rather than assumed.
- Assigned risks or safety net availability. The RICS ARP provides a route for firms that cannot place cover in the open market. Other bodies do not publish equivalents, so a practitioner who finds the market closing should engage their broker early.
What to ask before choosing your PI cover
Whether a surveyor is a sole practitioner regulated by FAS or a 50-partner RICS firm, the questions that drive a good PI placement are similar. Confirm which body or bodies regulate the practice and whether more than one set of rules applies. Identify the contractual PI demands from clients — lender panels, public-sector procurers and major developers all bring their own requirements. Check that the limit matches the higher of the body's minimum and the contractual demands placed on the firm. Confirm the basis of cover is civil liability and that defence costs are in addition to the limit, or understand the consequences if they are not. Establish what aggregation applies and whether reinstatement is included. Plan run-off cover in advance of any change of legal entity, merger, retirement or cessation, rather than treating it as a last-minute item. Ask the broker to walk through the exclusions and confirm how each one interacts with the actual scope of work the practice undertakes.
A broker who works in this market regularly should be able to map these questions onto a specific firm's circumstances and produce a placement that satisfies the regulatory minimum and the contractual demands without unnecessary cost. The Apex team is happy to discuss any of the above with surveyors thinking about their renewal or about a change of practice structure — readers can get in touch to arrange a conversation.
When each body's regime suits which buyer
Different bodies suit different practitioners, and the PI regime is only one input to that decision. A chartered surveyor whose work centres on residential valuation for mortgage lenders, commercial valuation or major project work will generally be RICS-regulated because of the market expectation rather than because of a free choice of regulator. The prescriptive RICS MTC fits that population because the work touches consumers, lenders and major counterparties whose own risk frameworks expect a standardised, predictable PI position.
A building surveyor working in a small practice whose scope is limited to defect surveys, party wall work and project monitoring may be well served by FAS or CABE regulation, where the lighter PI regime matches the lower exposure profile. The practitioner still needs cover that genuinely matches the work undertaken, but the regulatory prescription is calibrated to the population rather than to the highest-exposure cases.
A technical surveyor in a niche practice — for example, plant and machinery valuation, telecoms infrastructure surveying or specialist heritage work — may find that the choice of body is driven by membership eligibility and professional identity rather than by PI considerations. In those cases, the contractual PI demands from clients are likely to be the dominant driver of the placement, and the body's published minimum is often a floor rather than a ceiling.
None of these positions is inherently better than another. They are different calibrations for different populations, and a well-arranged PI policy translates the regulatory baseline and the contractual reality into a single placement that the practitioner can rely on.
Frequently asked questions
Is RICS PI cover more expensive than cover for FAS or CABE members?
Premium depends on a wide range of factors — fee income, claims history, scope of work, limit purchased, deductible and the insurer's view of the practice. As a general observation, the MTC prescription on each-and-every-claim cover and defence costs in addition removes commercial choices that can reduce premium in less prescriptive regimes, so RICS cover often carries a higher base cost for an equivalent practice. The differential is not uniform and should be assessed for the specific firm.
Can a surveyor be regulated by more than one body at once?
Yes. Dual membership is common, particularly between RICS and bodies such as CABE or CIOB where members hold complementary qualifications. Where more than one body's rules apply, the practitioner should ensure the PI policy meets the higher of the requirements on each dimension — typically the RICS MTC where RICS is one of the bodies in the mix.
Does the RICS MTC apply if a firm is only doing non-regulated work?
The MTC applies to RICS-regulated firms and to RICS members carrying out regulated work. A firm that holds itself out as RICS-regulated or that meets the principal-membership test is within the regime regardless of the specific work being done at a point in time. Practitioners who think their scope might fall outside RICS regulation should take advice from RICS directly before relying on that conclusion.
What happens if a firm cannot obtain RICS-compliant cover on the open market?
The RICS Assigned Risks Pool exists for that situation. The ARP is intended as a short-term placement at a higher premium, and firms in the ARP typically need to demonstrate a route back to open-market cover. The ARP is one of the distinguishing features of the RICS regime and has no published equivalent among the smaller bodies.
Is six years of run-off enough?
Six years aligns with the statutory limitation period for contractual claims in England and Wales and is the period required by RICS. It does not capture every possible long-tail claim — latent damage and certain tortious claims can sit on longer timescales. Practitioners with significant historic valuation or structural exposure sometimes choose to maintain run-off voluntarily beyond the regulatory minimum.
Do lenders require RICS-regulated surveyors specifically?
Many mortgage lenders maintain panels that require RICS membership and MTC-compliant PI cover. A non-RICS surveyor undertaking residential valuation for a lender on that lender's panel will typically face PI requirements that mirror the RICS position regardless of their own body. Practitioners working outside lender panels have more flexibility but should confirm the position with each client.
How often does RICS update the MTC?
RICS reviews its MTC and the associated fee-income bandings periodically. Practitioners should check the current MTC version published by RICS at each renewal rather than relying on a previous year's understanding. The figures and rule positions in this article are correct to the best of our understanding at the time of writing in May 2026 and are subject to change.
Does PI cover automatically include cyber, EPL or directors' and officers' exposure?
No. PI cover responds to professional liability arising from the provision of professional services. Cyber, employment practices and directors' and officers' liability are separate cover lines with their own wordings and limits. A surveying practice should consider these alongside PI rather than assuming any one policy covers the full risk picture.
