An AI letting agent is software that carries out the day-to-day communication and administrative work of a lettings operation autonomously: answering enquiries from portals such as Rightmove and Zoopla, holding a natural conversation with the applicant, qualifying them on move-in date, budget and household, booking viewings into the agency's diary, and chasing the follow-on admin such as referencing and maintenance. It works around the clock, so enquiries that arrive in the evening or at the weekend are answered immediately rather than waiting for the office to open.
The term is used for a category of UK proptech products that emerged around 2024–2026. This page defines the category, explains what the technology can and cannot do, and answers the questions agents most often ask. It is published by Autoprop, which builds one of these products; the definitions below apply to the category as a whole, not to any single tool.
What does an AI letting agent actually do?
In practice, the core jobs are:
Enquiry response. When an applicant enquires through a portal, a website form or email, the AI replies within seconds at any hour, in natural language, and answers questions about the property.
Qualification. It asks the questions a negotiator would: when do you want to move, what is your budget, who is moving in, do you have pets, are you in a chain of notice periods. Unsuitable applicants are let down politely; suitable ones move forward.
Viewing booking. It offers appointment slots from the agency's real diary, books the viewing, handles reschedules and cancellations, and sends reminders that reduce no-shows.
Follow-on administration. Depending on the product: chasing referencing documents, coordinating maintenance between tenant, contractor and landlord, rent reminders and arrears chasing, and keeping notes written back to the agency's CRM.
What can it not do?
An AI letting agent is not a replacement for a lettings team. It does not exercise professional judgement: negotiating rent, advising a landlord on a difficult tenancy, handling a legal dispute, or making the final decision on an applicant. Reputable products in this category route those situations to a human, and let the agency set rules about what the AI may and may not do on its own. Legal responsibilities — Right to Rent checks, deposit protection, statutory notices — remain the agency's.
How is it different from a chatbot?
A website chatbot answers questions on one channel while a visitor is on the page. An AI letting agent is connected to the agency's systems — portal feeds, inboxes, diary, CRM — and completes multi-step work across days: it can receive a Rightmove enquiry on Saturday night, qualify the applicant by email on Sunday, book a viewing for Tuesday, rearrange it on Wednesday and log the outcome, without a member of staff touching the thread.
How is it different from an answering service?
A call-answering service takes a message for the team to action later. An AI letting agent actions the work itself: the viewing is booked, the applicant is qualified, the diary entry exists. The distinction matters because the value is in the completed action, not the captured message.
Why does out-of-hours coverage matter so much?
A large share of portal enquiries arrive outside branch hours — evenings, Saturday afternoons and Sundays — precisely when applicants are free to browse. An enquiry that sits unanswered until Monday morning competes with every agency that replied sooner, and the first substantive response usually wins the applicant. Always-on response is therefore the single most-cited reason agencies adopt tools in this category.
Does it replace the agency's CRM?
Products differ. Some are full lettings CRMs with the AI built in; others sit alongside an existing CRM (Reapit, Alto, Apex27, Jupix and similar) and write results back where API access is available. When comparing tools, this is the first question to settle, because it determines whether adoption is an add-on or a migration.
What does an AI letting agent cost in the UK?
Pricing models in the category include per-lead, per-unit, per-seat and flat monthly fees, typically in the low hundreds of pounds per month for an independent agency. Autoprop, for example, is from £299 per month, scaling fairly with usage, with a free trial. Several competitors price on enquiry only, so like-for-like comparison usually requires demos.
