AI rules for estate agents: TPO, National Trading Standards and RICS

Aipedia, by the Apex broking team · Last reviewed 2026-10-27

There are no AI-specific rules for most UK estate and letting agents, so existing duties in the TPO Code, the DMCC Act 2024 and data protection law apply to AI use. RICS-regulated agencies also face a mandatory AI standard from 9 March 2026.

Part of: AI in estate and letting agents

In short

National Trading Standards, The Property Ombudsman and Propertymark have not published AI guidance for agents. The TPO Code for residential estate agents (March 2026 edition) does not mention AI, but its marketing clauses apply to AI output: 7i accuracy and material information, 7j seller approval, 7m liability for doubtful statements, 7n honest ads and 7o third-party material. Section 226 of the DMCC Act 2024 makes misleading overall presentations unlawful. UK GDPR Articles 22A to 22D govern automated significant decisions such as tenant rejection. The RICS standard on responsible AI use is mandatory for RICS-regulated agencies.

Who regulates estate and letting agents

Estate agency in the UK is regulated through a mix of statute, redress schemes and professional bodies rather than a single licensing regulator.

The National Trading Standards Estate Agency Team (Powys) oversees the Estate Agents Act 1979, issues prohibition and warning orders against people unfit to practise, and approves redress schemes.
The National Trading Standards Letting Agency Team (Bristol) enforces the Tenant Fees Act 2019 in England and issues penalties for missing redress or client money protection membership.
The Property Ombudsman runs a redress scheme with Codes of Practice approved by the Chartered Trading Standards Institute.
Propertymark is the professional body, with conduct and membership rules for members.
RICS regulates firms and members that are RICS-regulated, including some agencies.

What each body has said about AI

Body	AI publication	Status
National Trading Standards (estate and letting teams)	No AI guidance on the team pages	Existing law applies
The Property Ombudsman	None; the March 2026 Code does not mention AI	Code clauses apply to AI output
Propertymark	No AI material found	Conduct rules apply
ASA	No AI-specific property guidance; CAP News on altered imagery, 11 September 2025	Advertising codes apply
RICS	Responsible use of artificial intelligence in surveying practice, 1st edition September 2025	Mandatory professional standard from 9 March 2026 for RICS members and regulated firms

So for an agent that is not RICS-regulated, the question is not "what are the AI rules?" but "how do the existing rules apply when a tool did the work?"

The TPO Code clauses that matter most

The TPO Code of Practice for Residential Estate Agents (England, March 2026 edition) contains the duties most often engaged by AI tools:

7i: comply with consumer protection law; statements accurate and not misleading; all material information disclosed with no material omissions.
7j: particulars agreed with the seller before marketing.
7m: liability for anything in the particulars the agent has reason to doubt.
7n: advertisements legal, decent, honest and truthful.
7o: permission needed for third-party material, relevant to AI-generated or scraped images and text.
1h: confidential information used only for the purpose given, and data protection compliance.
1i and 18t: full written records for six years, including emails and digital messages.
4c: comparable evidence for market appraisals retained on file.
5f and 9b: customer due diligence on sellers and buyers; 9c: contemporaneous records of all offers.
18p: the definition of material information.

Consumer law: DMCC Act section 226

Section 226 of the Digital Markets, Competition and Consumers Act 2024, in force from 6 April 2025, defines misleading actions. A practice is misleading if it contains false information, or if its overall presentation is likely to deceive the average consumer even where every detail is true. This is the provision most relevant to AI-staged photos, enhanced images, AI-written descriptions and generated video tours, because the problem with AI content is often the overall impression rather than one false fact. A staged room may contain no false statement, yet still leave a buyer with the wrong idea of size, condition or setting. Agents should therefore review AI marketing as a whole, asking what an ordinary buyer or tenant would take from it, not just whether each line can be defended. The same test applies to chatbot answers and generated social media content.

Material information

National Trading Standards published Part A material information guidance on 12 July 2022, covering price, council tax band and tenure, with Parts B and C then in development. Agents using AI or data tools to populate these fields remain responsible for them under TPO 7i. The government's June 2026 announcement on home buying and selling reform, including intended homebuying sales packs, is noted on the material information page. See AI and material information.

Data protection and automated decisions

UK GDPR Articles 22A to 22D, in force from 5 February 2026, require safeguards where a significant decision is made solely by automated means: information, the ability to make representations, human intervention and the right to contest. Automated tenant referencing or rejection is a clear example. The Data (Use and Access) Act provisions were brought into force by SI 2026/82. TPO Code 1h adds a confidentiality duty for vendor, landlord and tenant data entered into AI tools. See AI tenant referencing.

The RICS AI standard for regulated agencies

RICS-regulated agencies and valuers must follow the RICS standard where AI materially affects service delivery. It requires a written AI systems register, a risk register reviewed at least quarterly, documented reliability decisions on material AI outputs, advance written client disclosure, and competence and procurement due diligence. See what the RICS AI standard means for PI and telling clients you use AI.

What it means in practice and for PI

No UK ruling, ASA adjudication or National Trading Standards action specifically about AI use by an estate or letting agent has been found. That does not mean there is no risk: complaints and claims will be decided under the existing duties above. In practice, agents should build human checks around every AI output that reaches the public, keep records of what the tool produced and what a person approved, and review their PI wording. No regulator has made a statement on AI and PI. See does estate agents' PI cover AI mistakes? and AI in estate and letting agency.

Frequently asked

Are there AI-specific rules for UK estate agents?

Not for most agents. National Trading Standards, The Property Ombudsman and Propertymark have not published AI guidance. Existing duties in the TPO Code, the DMCC Act 2024 and data protection law apply. RICS-regulated agencies must also meet the RICS AI standard.

Does the TPO Code mention AI?

No. The March 2026 edition of the Code of Practice for Residential Estate Agents does not mention AI. Its clauses on accurate marketing (7i), seller approval (7j), doubtful statements (7m), honest ads (7n) and third-party material (7o) still apply to AI output.

When did the RICS AI standard become mandatory?

The RICS professional standard on responsible use of AI in surveying practice, first published in September 2025, became mandatory on 9 March 2026 for RICS members and regulated firms where AI materially affects service delivery.

Has any agent been penalised for AI use?

We are not aware of any UK ruling, ASA adjudication or National Trading Standards action specifically about AI use by an estate or letting agent. Complaints would be judged under existing rules.
