RICS residential valuation and survey standards: what applies in 2026

Reviewed by the Apex broking team · Last reviewed 2026-08-22 · Position stated as at August 2026

Two frameworks, two different jobs

• The Home Survey Standard is an RICS professional standard covering the delivery of condition-based surveys of residential property. It is where Levels 1, 2 and 3 come from.
• The Red Book — formally RICS Valuation – Global Standards — governs the production of a valuation. It applies wherever a written opinion of value is given, residential or otherwise, subject to the exceptions in the standard itself.

A Level 2 survey with a valuation engages both. A Level 3 survey without a valuation engages only the first. A mortgage valuation for a lender engages the second and not the first. Getting that mapping right in the terms of engagement is the single most useful risk control available to a residential practice.

The Home Survey Standard

The Home Survey Standard is an RICS professional standard, published on 2 November 2020 and effective from 1 March 2021. It defines three levels of service:

• Home Survey Level 1 — the most limited inspection and report, giving an overview of condition without extensive detail.
• Home Survey Level 2 — a more detailed inspection and report, available with or without a valuation.
• Home Survey Level 3 — the most thorough inspection and report, covering the construction and condition of the property in detail.

The levels are service definitions, not report titles, and the standard is concerned with matching the service to the client’s needs, describing the scope clearly, and reporting consistently within the level agreed.

The Red Book

The current global edition is RICS Valuation – Global Standards, published and effective from 31 January 2025. It incorporates the International Valuation Standards, which were published on 31 January 2024 and became effective on 31 January 2025.

In the United Kingdom the global standards are read with the RICS Valuation – Global Standards: UK national supplement, published on 19 October 2023 and effective from 1 May 2024, reissued in January 2025 to align with the updated global standards.

For residential work the relevant part of the UK supplement is UK VPGA 11, which covers the valuation of UK residential property. RICS describes the revised UK VPGA 11 as setting high-level principles for residential valuation as a whole rather than going into significant detail on residential mortgage valuation specifically, and has indicated that a dedicated professional standard for residential valuations for owner occupation is in development. As at August 2026 we cannot confirm a publication date for that standard, so this page does not state one.

Why the standards drive PI claims

Three patterns account for most residential surveyor claims, and all three are really scope arguments.

• Scope mismatch. The client believes they bought an investigation; the surveyor delivered the level engaged. Where the terms of engagement do not describe the level clearly, the argument is one the surveyor has to win on documents that were never written to win it.
• Defects not reported. A defect a competent surveyor should have identified within the agreed level, or one that was visible and not followed up. The standard of care is that of the reasonably competent surveyor undertaking that level of service, which is why the standards are evidence in these claims — see Bolam for surveyors and valuers.
• Valuation accuracy. Where a valuation is challenged, the argument is usually about whether the figure fell outside the range a competent valuer could have reached. Our page on the permissible margin of error covers how the courts have approached that.

The related case law is worth knowing: Smith v Eric S Bush on the surveyor’s duty to the purchaser and the limits of disclaimers, Hedley Byrne on assumption of responsibility, and Merrett v Babb on the personal liability of the signing surveyor.

What this means for the PI programme

RICS sets its own professional indemnity insurance requirements for regulated firms, separately from the practice standards above. The current UK requirements took effect on 1 July 2024 and set a minimum level of indemnity by turnover: £250,000 where turnover is £100,000 or less, £500,000 for turnover between £100,001 and £200,000, and £1,000,000 where turnover is above £200,000.

Alongside the limit, the requirements set a maximum uninsured excess of the greater of 2.5% of the sum insured or £10,000 for limits of £10,000,000 or less, require cover on a full civil liability basis using the RICS minimum policy wording or something more comprehensive, and require firms ceasing practice to obtain fully retroactive run-off — including, for consumer claims, a limit of £1,000,000 in all for six years from expiry of the policy at cessation.

For residential practices there are two further points to raise with a broker. First, whether the wording carries any restriction on external wall or fire safety work, which the RICS minimum wording contemplates as a permitted exception. Second, how aggregation operates where a single error is repeated across many reports, which is covered on aggregation under the RICS minimum wording.

Practical points for a residential practice

• State the survey level in the terms of engagement, in the report, and in the fee quote, using the standard’s own language.
• Where a Level 2 is delivered with a valuation, make explicit that the valuation is a Red Book valuation and identify the basis of value.
• Record what could not be inspected and why. Most disputes about a missed defect become disputes about whether the limitation was properly reported.
• Do not let the service drift upward without changing the engagement. Answering detailed questions after a Level 1 is how a Level 1 becomes a Level 3 in the client’s mind.
• Keep the site notes and the photographs. In a claim brought years later they are the only contemporaneous evidence of what was visible on the day.

Frequently asked questions

What are the RICS home survey levels?

The RICS Home Survey Standard defines three levels of service. Level 1 is the most limited inspection and report, giving an overview of condition. Level 2 is a more detailed inspection and report, available with or without a valuation. Level 3 is the most thorough, covering construction and condition in detail. They are definitions of service, not report titles. A fuller description of using a specialist broker for surveyors PI sits on its own page.

Is the Home Survey Standard the same as the Red Book?

No. The Home Survey Standard governs condition-based residential surveys and defines Levels 1, 2 and 3. The Red Book — RICS Valuation – Global Standards — governs the production of valuations. A Level 2 survey with a valuation engages both frameworks; a Level 3 survey without a valuation engages only the Home Survey Standard.

Which edition of the Red Book applies in 2026?

RICS Valuation – Global Standards published and effective from 31 January 2025, incorporating the International Valuation Standards effective on the same date. In the UK it is read with the UK national supplement published on 19 October 2023 and effective from 1 May 2024, reissued in January 2025 to align with the updated global standards.

Has the Home Survey Standard been replaced by a second edition?

Not as far as we have been able to confirm. RICS consulted on a second edition, with the consultation closing on 14 October 2025, and in April 2026 said it was still working through the consultation comments with an updated publication timeline to follow. We cannot confirm a publication or effective date, so this page states the first edition position. Check the RICS standards pages before relying on it.
