Ethics is the only mandatory competency assessed at Level 3, the assessor guidance instructs that it must be tested to a greater extent than anything else, and the chairperson is required to put specific ethics questions to you. Fall short here and the panel must refer you, whatever else went well in the hour.
That sounds severe. It is also the most predictable part of the interview, because the scenario families repeat and the correct answer structure is stable. What changes is the framework underneath, and it has changed recently: two of the supporting standards are new since late 2025. Here is the current ground, and how to stand on it.
The framework you are answering from
The five Rules of Conduct (effective February 2022, unchanged since) are the spine of every answer:
- Honesty, integrity and compliance with professional obligations, including obligations to RICS.
- Maintain professional competence, and ensure services are provided by competent individuals with the necessary expertise.
- Provide good-quality and diligent service.
- Treat others with respect and encourage diversity and inclusion.
- Act in the public interest, take responsibility for your actions, and act to prevent harm and maintain public confidence in the profession.
They rest on six ethical principles: honesty, integrity, competence, service, respect and responsibility. Each rule comes with example behaviours, and citing the relevant behaviour ("Rule 1, the improper influence behaviour") is the difference between a memorised list and working knowledge.
The supporting standards move, and 2026 candidates need the current set:
- Countering financial crime (2nd edition, effective 17 December 2025) replaced the 2019 bribery and money laundering statement, adding sanctions screening duties and addressing AI-enabled fraud and digital assets. It carries the absolute line every candidate should know: nothing may be offered or accepted, directly or indirectly, that could constitute a bribe.
- Conflicts of interest (professional statement, 2017) remains current, with its three conflict types and the prior informed consent regime. An updated edition has been signalled for consultation, so know the 2017 document as the mandatory one and watch for change.
- Responsible use of artificial intelligence in surveying practice (effective 9 March 2026) is the new arrival, and panels treat it as an issue of current concern.
- The Professionalism module you complete before final assessment covers this ground, and passing it does not exempt you from ethics questioning in the room.
The answer structure that survives follow-ups
Assessor questioning probes in a chain: what would you do, then what if that fails, then who do you tell. A structure that holds through the chain:
- Identify the issue and name the rule engaged, ideally with the behaviour.
- State the obligations from the relevant standard, by name and edition.
- Act: the immediate practical steps, which almost always include pausing the instruction, documenting, and checking the firm's own policy.
- Escalate in order: line manager, then the firm's compliance or whistleblowing route, then RICS Regulation through its reporting channels, then statutory bodies where the law requires.
- Anchor in the public interest, which is Rule 5 doing its job, including the duty to report significant breaches, your own included.
The scenario families, under the current rules
Gifts and hospitality. A contractor you are certifying offers you rugby tickets during a live tender. The trap most candidates fall into is quoting a monetary limit, and there is none: no RICS document sets a gifts threshold. The correct answer runs on the bribe test (could this constitute or be perceived as improper influence, and timing makes the tender period close to decisive), the firm's own gifts and hospitality policy and register, declaration to your employer either way, and declining or escalating in doubt. The Countering financial crime standard expects registers of gifts, hospitality and donations, and expects facilitation payments to be refused.
Conflicts of interest. Classify it first: own interest, party conflict, or confidential information conflict. Then the discipline: do not continue while conflicted; proceed only with prior informed consent from all affected parties, and only where you are satisfied proceeding serves all of their interests; use information barriers that actually work; record the decisions; decline or step away where consent is unavailable. Conflicts must be checked throughout an assignment, and dual agency in UK commercial investment agency is banned outright.
Confidentiality. Client information is used only for the purpose given, with consent, or where the law requires or permits. The sharpest follow-up is the money laundering one: a suspicious activity report through the firm's reporting officer is required by law, and tipping off the client is itself an offence. Knowing that pairing signals genuine understanding rather than recital.
Acting beyond competence. Rule 2 is blunt: only take on work you have the knowledge, skills and resources to do competently. The professional options are to decline, to proceed under competent supervision, or to bring in specialists, always with the client aware of who is doing the work. A strong answer mentions the professional indemnity consequences of quietly winging it.
Pressure to alter figures. A director wants a valuation nudged, a client wants a claim inflated, an employer wants a cost report softened before a board meeting. Your opinion is evidence-based or it is nothing: correct genuine errors transparently, refuse changes without evidence, document the request and your response, and escalate up the chain, with RICS at the end of it for significant breaches. Recent published disciplinary decisions show document falsification treated as dishonesty carrying the severest sanctions, and that context strengthens an answer.
Backdating documents. However administrative it feels, dating a document to pretend it was issued earlier is misleading and treated as dishonesty. If a deadline was genuinely missed, the professional answer is to advise the client honestly about consequences and options, never to falsify the record.
Social media. The Rules apply online exactly as offline, on personal accounts as well as professional ones where conduct could undermine public confidence. Respectful criticism is fine; abusive or discriminatory conduct is regulatory territory. RICS updated its dedicated guidance on this in September 2024, having first published it in 2021.
AI use. The newest scenario family, and increasingly asked. The standard effective March 2026 requires competence in the tools you use, protection of confidential data, advance written disclosure to clients where AI materially affects service delivery, and a named, qualified surveyor accountable for judging output reliability. The principle to lead with: AI assists professional practice, with professional responsibility remaining the named surveyor's alone. And for your own APC: generative AI must not be used to produce any part of your submission, and submissions are checked.
Preparing without memorising
Panels want to watch you reason under the framework, on scenarios shaped like your own projects, rather than hear the rules recited. So rehearse aloud: pick two scenarios per family, answer them to a colleague using the five-step structure, and have them push the "what if that fails" follow-up until escalation feels automatic. It is the highest-return hour of interview preparation after the case study, and the full-length mock panel in the Cohort Programme drills exactly this questioning.
