Article 50 Guide for Agencies

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

Last reviewed 1 November 2026

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.

What applies to a property bot

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

The AI disclosure

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.

Answering questions about a property

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.

The energy rating

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.

Booking viewings

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 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.

Screening tenants

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. Check the current application dates, which the Digital Omnibus changed.
