Definition

In an APC context, methods of data gathering refers to the range of techniques a surveyor uses to collect the information needed to fulfil a client's instruction — from the initial client briefing through site inspection, desk research and third-party enquiries. The purpose is to build a sufficiently complete and reliable evidence base from which to form and document a professional opinion. The RICS Rules of Conduct (effective 2 February 2022) require members to act competently; selecting appropriate data-gathering methods is an expression of that competence.

Why this matters for Client Care

  • Inadequate data gathering is a leading cause of professional negligence claims; a systematic approach reduces risk for both surveyor and client.
  • Clients commission surveyors for their ability to identify, source and interpret information they cannot access themselves.
  • Assessors expect Level 2 candidates to explain which methods they used for a given instruction and why they were appropriate.
  • Data quality directly affects the reliability of conclusions; a well-gathered evidence base supports confident, defensible advice.
  • Understanding the limitations of each data source is as important as knowing how to use it.

Key principles

Client briefing and desk research

Every instruction begins with the client briefing, establishing scope, objectives and constraints. Structured desk research follows: reviewing title documents, planning history, Land Registry data and any existing reports. Desk research identifies known issues before the site visit, making fieldwork more targeted and efficient.

Site inspection

The site visit is the primary data-gathering event for most disciplines. The candidate must plan the inspection using a systematic methodology appropriate to the instruction — an elemental schedule for a building survey, a floor-by-floor measurement regime for an area schedule. Photographs, notes and measurements should be contemporaneous. Limitations (access restrictions, concealed areas) must be recorded and disclosed to the client.

Third-party enquiries

Many instructions require information from statutory authorities, utility companies, environmental search providers or specialist consultants. Responses should be obtained in writing and checked for currency. Where the surveyor relies on third-party information, the source and any caveats should be cited in the final report so the client understands the basis of the conclusion.

Comparable evidence

Valuation and some agency instructions require market evidence. Comparable evidence should be sourced from reliable databases, verified against primary sources where material, and adjusted for differences in location, specification, time and lease terms. The candidate should be able to explain their selection and adjustment process to an assessor.

Relevant RICS guidance and legislation

  • RICS Rules of Conduct (effective 2 February 2022) — Rule 3 (competence)
  • RICS Red Book Global Standards (effective 31 January 2022) — requirements for information gathering and reliance on third-party data in valuation
  • Data Protection Act 2018 / UK GDPR — personal data obtained during an instruction must be handled lawfully and securely

Ethics and Rules of Conduct angle

Rule 1 (Honesty and Integrity) requires the surveyor to accurately represent the evidence gathered and not selectively discard information that contradicts a preferred conclusion. Rule 3 (Competence) requires that methods are appropriate for the instruction and that the surveyor recognises when specialist input is needed. Failing to gather sufficient data, or relying on unreliable sources without disclosure, risks misleading the client.

APC-style Q&As

Q (Level 1)Name three primary methods of data gathering used by a surveyor at the inception stage of an instruction.

The three primary methods are: the client briefing (to understand objectives, scope and constraints); desk research (reviewing title documents, planning records and mapping data); and site inspection (physical examination of the property using a systematic methodology).

Q (Level 1)Why is it important to record the limitations of a site inspection?

Recording limitations — such as areas not inspected due to restricted access — is essential for honesty with the client about the basis of the advice and protects the surveyor from claims arising from matters that could not reasonably have been identified. The client can then decide whether further investigation is warranted.

Q (Level 2)On a building survey, the roof space was not accessible. How do you handle this in your report?

(example) I noted clearly in the report that the roof space could not be inspected due to a fixed hatch with no ladder available, explained why this was significant (thermal insulation, structural timber condition, water ingress), and recommended a specialist inspection before exchange of contracts. I also provided a provisional cost range for likely remediation based on the age and construction type visible externally, so the client had a sense of potential exposure.

Q (Level 2)How do you assess the reliability of comparable evidence used in a valuation?

Reliability depends on the source, currency and degree of similarity to the subject property. I verify key transactions against primary sources — Land Registry records or direct agent confirmation — rather than relying solely on database figures. I consider how recently the comparable transacted, whether deal terms are known, and how significant the adjustments required are. The larger the adjustment, the less reliable the comparable as a direct pointer to value.

Q (Level 3)You are undertaking a secured lending valuation and the client is pressing you to complete quickly. Your desk research reveals a pending planning application affecting the subject property. The client says it is not material. How do you proceed?

I would not defer to the client's assertion without investigation. A pending planning application can be highly material to value. I would obtain and review the application documents, assess the possible outcomes and their likely impact, and if necessary consult a planning specialist. My report would reflect the planning uncertainty explicitly, including any appropriate assumptions. If the client's pressure to overlook material information persisted, I would document my professional position in writing and consider whether I could continue to act.
