The RICS rules of conduct matter because they define the professional standard expected of RICS members and regulated firms. For a quantity surveyor, they are not abstract ethics statements. They affect how you price work, report risk, communicate with clients, manage records, challenge poor behaviour, deal with conflicts and maintain public confidence in the surveying profession.
A chartered surveyor can be technically strong and still create professional risk if they fail to communicate clearly, work outside their competence, ignore a conflict of interest, treat people unfairly or allow commercial pressure to override professional judgement. That is why the Rules of Conduct should be understood as part of everyday QS practice, not something to revise only before an APC interview or disciplinary issue.
This guide explains what the five RICS Rules of Conduct mean in practice, how they apply to quantity surveyors in the UK construction industry, and how APC candidates, MRICS members and commercial teams can use them as a practical decision-making framework.
Quick Answer: What Are the RICS Rules of Conduct?
The RICS Rules of Conduct are the core professional rules that apply to RICS members and regulated firms. They cover honesty, integrity, professional competence, service quality, respect, inclusion, public interest, responsibility and public confidence. In practical terms, they require surveyors to act professionally, work within their competence, deliver a diligent service, treat others properly, take responsibility for their actions and avoid conduct that damages trust in the profession.
For quantity surveyors, the rules are especially relevant when dealing with cost reports, valuations, payment notices, compensation events, final accounts, procurement advice, claims, tender evaluations, client communications and internal commercial reporting. A QS is often trusted with financial information that affects clients, contractors, subcontractors, employers and public bodies. That makes professional conduct central to the role.
RICS Rules of Conduct
RICS Rules of Conduct at a Glance
| Rule Area | Plain English Meaning | QS Example |
|---|---|---|
| Honesty and integrity | Be truthful, transparent and professionally accountable. | Do not hide an overspend, inflate a valuation or present uncertain assumptions as fact. |
| Competence | Work within your knowledge and keep your skills current. | Seek senior or specialist input before advising on complex claims, legal issues or expert matters. |

Why the RICS Rules of Conduct Matter for Quantity Surveyors
Quantity surveying is a commercial profession, but it is also a trust-based profession. Clients, employers and project teams rely on the QS to report financial information accurately, administer contract mechanisms properly and give professional advice that is not simply shaped by convenience or short-term pressure.
The Rules of Conduct matter because they turn professional judgement into an accountable standard. A QS may be asked to approve an inflated forecast, delay reporting a risk, understate a compensation event, ignore a conflict in procurement or soften advice to avoid a difficult conversation. In each case, the rules give the surveyor a professional anchor.
They also matter for career progression. APC candidates are assessed on ethics and professional practice. MRICS members must maintain competence and CPD. Commercial managers are expected to set the tone for their teams. Regulated firms must have systems that support competent, ethical and responsible service delivery.
The Five RICS Rules Explained in Plain English
Rule 1: Honesty, integrity and professional obligations
This rule is the foundation. It means a chartered surveyor must be truthful, transparent and professionally accountable. In QS practice, this affects cost reporting, valuations, tender advice, final account negotiations and contractual notices. You should not manipulate data, hide known risks, mislead a client or allow commercial pressure to distort your advice.
A practical example is a monthly CVR or cost report. If a package is forecast to overspend, the professional response is not to bury the issue in a vague risk note. The QS should explain the position, identify the cause, quantify the exposure where possible and record the assumptions behind the forecast.
Rule 2: Competence and appropriate expertise
This rule means surveyors must maintain professional competence and make sure services are provided by people with the right expertise. For a QS, this is important because construction contracts, measurement rules, procurement routes and cost advice can be technically complex.
Competence does not mean knowing everything. It means understanding the limits of your knowledge, seeking support when needed and avoiding work you are not properly equipped to undertake. A junior QS should not be left to advise on a complex loss and expense claim without supervision. A senior QS should not present specialist tax, legal or planning advice as if it were within their professional expertise.
Rule 3: Good-quality and diligent service
This rule is about the standard of service provided to clients, employers and those who rely on the surveyor. For QSs, it means timely, careful, evidence-based work. A poor-quality cost plan, unsupported valuation, late payment assessment or vague final account recommendation can create commercial harm.
Diligence includes record-keeping. In practical QS work, good records help support valuations, variations, compensation events, instructions, change control, payment notices and dispute avoidance. If a decision cannot be explained months later, the commercial file is weak.
Rule 4: Respect, diversity and inclusion
This rule requires surveyors and firms to treat people with respect and encourage diversity and inclusion. In construction, this is relevant because QSs often work across site teams, clients, subcontractors, consultants, supply chain partners and internal departments. Professional behaviour is not limited to formal client meetings. It applies to site conversations, emails, commercial meetings, interviews, negotiations and team management.
For a commercial manager or senior QS, this also means challenging poor behaviour when it appears. A high-performing team cannot be built on intimidation, discriminatory comments, bullying or exclusionary practices. The professional standard is not only about how you act personally, but also about what behaviour you allow to become normal around you.
Rule 5: Public interest, responsibility and public confidence
This rule is particularly important because RICS is a public-interest profession. Surveyors are not only service providers; they are professionals whose work can affect safety, value, public money, built assets, housing, infrastructure and market confidence.
For quantity surveyors, public interest can arise in public sector procurement, building safety expenditure, housing maintenance, infrastructure investment, valuation advice, cost benchmarking and claims involving public funds. Taking responsibility means acknowledging errors, correcting records, escalating material risks and avoiding conduct that could reduce confidence in the profession.
How the Rules Apply to Everyday QS Work
The Rules of Conduct become useful when translated into day-to-day commercial decisions. A QS may not use the words honesty, competence or public interest every day, but the principles sit behind common commercial tasks.
When preparing a valuation, the QS should make sure quantities, rates, progress percentages and supporting evidence are reasonable. When preparing a cost report, the QS should separate actual cost, committed cost, forecast cost and risk allowances. When assessing a compensation event, the QS should focus on contractual entitlement, evidence and forecast effect rather than negotiation pressure alone.
The same logic applies to procurement. If a QS is involved in tender analysis, they should treat tenderers fairly, manage conflicts and record the basis of recommendation. If they are involved in subcontractor payment, they should assess applications properly and avoid using administrative delay as a commercial tactic. If they are advising a client, they should be clear where assumptions, exclusions and limitations apply.
QS Conduct Risks
Where RICS Conduct Issues Commonly Appear in QS Work
Cost reporting
Weak forecasts, hidden risks, unclear assumptions or pressure to improve margin artificially.
Valuations and payments
Unsupported progress assessments, poor records or failure to follow contract payment procedures.
Procurement
Conflicts of interest, unfair tender treatment, poor audit trails or unclear recommendation criteria.
Change and claims
Inflated submissions, weak entitlement checks, missing notices or unclear assessment logic.
Team culture
Disrespectful behaviour, bullying, exclusion or failure to challenge poor conduct in commercial teams.
Competence
Acting outside expertise, poor supervision of junior staff or failure to keep technical knowledge current.
Use this as a practical internal checklist for QS teams, APC candidates and commercial managers.
Common Mistakes That Put Surveyors at Risk
Most conduct issues do not begin with a dramatic breach. They often start as small compromises: weak records, unclear advice, unmanaged conflicts, poor supervision, overconfidence or a decision to stay quiet when something looks wrong.
- Working outside competence: A QS should recognise when specialist advice is needed, particularly on legal, tax, planning, technical design or complex expert matters.
- Poor evidence trails: Commercial decisions should be supported by documents, dates, assumptions and reasoning, especially where money or entitlement is disputed.
- Blurred conflicts of interest: A surveyor should be transparent where a personal, commercial or organisational interest may affect judgement.
- Overstating certainty: A QS should distinguish between known facts, reasonable assumptions, forecasts and opinion.
- Poor communication: Delays, vague reporting and unexplained changes can create professional risk even where the technical answer is broadly right.
- Ignoring disrespectful behaviour: Bullying, discriminatory language or exclusion in project teams should not be treated as normal construction culture.
RICS Rules of Conduct and the APC Ethics Competency
For APC candidates, the Rules of Conduct are central to ethics, professional practice and final assessment preparation. Candidates should not memorise the rules mechanically and then struggle to apply them. The stronger approach is to connect each rule to real project examples.
A quantity surveying APC candidate might explain how they maintained integrity in a valuation, how they knew when to seek senior review, how they recorded assumptions in a cost plan, how they dealt with a conflict in procurement, or how they challenged inappropriate behaviour in a meeting.
The best APC answers are practical. Assessors want to see that the candidate understands professional obligations and can apply them under commercial pressure. It is not enough to say that surveyors should act ethically. You should be able to explain what you actually did, why it mattered, what rule or principle it related to, and what you learned from it.
RICS CPD and Maintaining Professional Competence
Professional competence does not stop once someone becomes MRICS. Chartered surveyors must keep their knowledge current through continuing professional development. For QSs, this should include contract updates, procurement changes, cost management practice, building safety, digital tools, sustainability, professional ethics and sector-specific knowledge.
A practical CPD plan for a QS should be linked to real responsibilities. If you assess NEC compensation events, CPD on accepted programmes, early warnings and quotation assessment is relevant. If you work in public procurement, CPD on transparency, conflicts and social value may be relevant. If you manage a team, CPD on supervision, equality, inclusion and professional decision-making is also valuable.
How Firms Can Embed the Rules into Commercial Practice
Regulated firms and commercial teams should not treat the Rules of Conduct as a document saved in a compliance folder. The rules need to appear in systems, supervision, training and decision-making. This is especially important where teams are under pressure to improve margin, close out final accounts, defend claims or accelerate reporting.
- Use standard reporting templates: Cost reports, CVRs and dashboards should make assumptions, risks, exclusions and evidence visible.
- Maintain clear approval routes: High-value payments, claims, tender recommendations and final account settlements should have appropriate review and sign-off.
- Record conflicts: Conflict checks should be part of procurement, consultant appointment, expert witness and client-advisory work.
- Train junior staff: Assistant QSs should understand not just what to do, but why the record, notice or valuation matters professionally.
- Encourage escalation: Staff should know how to raise concerns where they believe professional standards are being compromised.
- Review lessons learned: Recurring commercial errors should be treated as competence and process issues, not just individual mistakes.
Practical Application
Turning the RICS Rules into Practical QS Behaviours
| Professional Principle | What a QS Should Do | Evidence to Keep |
|---|---|---|
| Integrity | Report commercial risk clearly, even where the message is uncomfortable. | Cost reports, risk registers, meeting notes and email advice. |
| Competence | Escalate complex issues and avoid presenting specialist advice outside your expertise. | Review notes, senior sign-off, CPD records and specialist input. |
| Diligence | Check quantities, rates, notices, payment dates, assumptions and contract requirements. | Valuation files, take-off records, notices, assessments and audit trails. |
| Respect | Communicate professionally and challenge poor behaviour in meetings or correspondence. | Meeting actions, escalation records, training records and HR/process notes where relevant. |
| Public confidence | Correct mistakes, disclose material issues and avoid conduct that undermines trust. | Correction records, revised reports, client notifications and lessons learned. |
A QS should be able to explain the judgement behind a commercial decision, not just the number in the report.
What This Means Today
In 2026, the RICS Rules of Conduct are especially important because surveying work is becoming more visible, more data-led and more exposed to public scrutiny. Clients expect faster reporting. Contractors face margin pressure. Public bodies expect better governance. Digital tools make information easier to process, but they also increase the importance of accountability and professional judgement.
For a quantity surveyor, the practical lesson is simple: do not treat conduct as separate from commercial management. The way you prepare a valuation, record a compensation event, issue advice, manage a conflict, supervise a junior QS or challenge poor behaviour is part of your professional identity.
The safest QS is not the one who avoids difficult decisions. It is the one who makes decisions transparently, records the basis of advice, stays within competence, respects others and understands that professional trust is built through repeated, disciplined conduct.
