AI chatbots for estate agents and lettings: disclosure, viewings and what the bot may say

A guide drafted by an AI agent outlines how estate agents and letting agencies should deploy property chatbots under the EU AI Act's Article 50, requiring an AI disclosure at the first message and grounding answers about size, price, condition and energy ratings in listing data rather than model output. It notes that energy performance indicators must be stated in property adverts under the Energy Performance Buildings Directive, that tenant pre-screening must not filter on protected grounds, and that creditworthiness scoring tools may qualify as high-risk AI systems under Annex III. The guide cites Moffatt v. Air Canada (2024 BCCRT 149) as precedent that an agent is responsible for what its chatbot tells customers.

This guide was drafted by an AI agent from the primary sources linked at the bottom, and has not been reviewed by a lawyer. It is general information, not legal advice. The original is at https://mdodeja.github.io/eu-ai-act-article-50-guide/guides/estate-agent-property-chatbot-ai-disclosure.html https://mdodeja.github.io/eu-ai-act-article-50-guide/guides/estate-agent-property-chatbot-ai-disclosure.html . Short answer. A property chatbot needs the Article 50 AI disclosure in its first message, like any other chatbot. The bigger risks are in what it says. Answers about a property's size, price, condition or energy rating are the agent's statements, so they should come from the listing data, not the model. Energy performance indicators have to appear in property adverts under EU energy law, and a bot that screens tenants must not filter people by ethnic origin or other protected grounds. Where a tool scores applicants' creditworthiness, check whether it is a high-risk AI system. | Part of the chat | Rule | What to do | |---|---|---| | Bot greets the visitor | AI Act Article 50 1 and 5 | Say it is an AI, at the latest at the first message | | Questions about a property | Unfair Commercial Practices Directive | Answer from the listing data only | | Energy rating | Energy Performance of Buildings Directive | Give the indicator from the certificate, never an estimate | | Booking a viewing | GDPR Articles 6 and 13 | Ask only what the viewing needs, with a short notice | | Pre-screening tenants | Race Equality Directive, GDPR | No questions or filters on protected grounds | | Scoring applicants' credit | AI Act Annex III, point 5 b | Check whether the tool is high-risk | Article 50 1 applies to any AI system that interacts directly with people, so a property assistant needs the disclosure before the visitor types. Property bots often take the name of a branch negotiator, which makes a clear first line more important: "Hi, I'm the AI assistant for Harbour Estates. I can answer questions about our listings and book viewings. A member of the team confirms every viewing." More wording options are in the disclosure wording guide https://mdodeja.github.io/eu-ai-act-article-50-guide/guides/chatbot-ai-disclosure-wording.html . Property buyers and tenants make large decisions from small facts. The Unfair Commercial Practices Directive treats false or deceptive information, and leaving out material information, as misleading practices. A bot that guesses "yes, it has parking", "the service charge is about EUR 1,200" when the listing says nothing creates exactly that risk, and the statement is the agent's. Practical limits: A Canadian tribunal held Air Canada responsible for a refund policy its website chatbot described wrongly Moffatt v. Air Canada, 2024 BCCRT 149, reported; not EU law . The same logic applies to a bot describing a flat. Under the Energy Performance of Buildings Directive, when a building or unit with an energy performance certificate is offered for sale or rent, "the energy performance indicator of the energy performance certificate" has to be stated in advertisements in commercial media Directive 2010/31/EU, Article 12 4 . The 2024 recast, Directive EU 2024/1275, carries this rule forward and adds the energy performance class, reported; national law sets the detail. For a bot, that means: when asked about energy, give the rating from the certificate, and don't estimate one from photos or the property's age. A viewing booking needs a name, contact details and a time. Give a short privacy line before asking "We use your details to arrange the viewing. Privacy policy: link " , and keep marketing consent as a separate, unticked choice. The sales and lead-capture guide https://mdodeja.github.io/eu-ai-act-article-50-guide/guides/ai-sales-lead-capture-chatbots.html covers consent for follow-up email. Say clearly whether the bot's booking is confirmed or still needs a person to confirm it. A visitor who arrives at a viewing nobody knew about blames the agent, not the bot. Letting bots are sometimes asked to pre-screen applicants. The Race Equality Directive 2000/43/EC bans discrimination on grounds of racial or ethnic origin in access to goods and services available to the public, "including housing" Article 3 1 h . National law usually adds other protected grounds. If a tool behind the bot scores applicants' creditworthiness, look at Annex III of the AI Act: AI systems intended to evaluate the creditworthiness of natural persons or establish their credit score are listed as high-risk point 5 b , with obligations well beyond Article 50.
