Rental bidding rules: an advert-to-offer workflow for letting agents

A letting agent in England must publish a specific asking rent and must not ask for, encourage or accept an offer above it. The control has to cover more than the portal advert: emails, texts, direct messages, social posts, viewing conversations and the rent entered in the tenancy record all need to follow the same figure.

If an applicant volunteers a higher offer, do not accept it. Record the message, reply that the property can only be considered at the advertised rent, and keep the selection decision separate from the amount offered. This article turns the rule into a practical workflow from landlord instruction to signed tenancy.

What the rental bidding rule covers

The GOV.UK guide for landlords says a landlord or letting agent cannot ask for, encourage or accept an offer higher than the advertised rent. A written advert or offer must state a specific amount; a range is not allowed. Written communications include online and printed adverts, social posts, emails, texts and direct messages. A physical “to let” sign is excluded from the written-advert definition.

The measures apply to assured periodic tenancies in England from 1 May 2026. The rule sits in section 56 of the Renters' Rights Act 2025, and the commencement regulations brought Chapter 6 of Part 1 into force on that date. The official council guidance says social and supported housing are outside these measures. Check the tenancy type before relying on an exception.

Hosting sites that only carry an advert are not liable under this rule, according to the official guidance. That does not remove the agency's responsibility for the advert it supplies or the messages its staff send through a portal.

Set one approved rent before anything is published

Start the file with the landlord's instruction and a single rent for the proposed letting. Record whether the amount is weekly or monthly and how it should appear on each channel. Reject wording such as “offers over”, “from £1,800” or a price range. The applicant should not have to infer the asking rent.

Treat the approved figure as locked for that marketing period. Theguidance for councils lists publishing another advert with a higher price for the same letting among the prohibited conduct. If the landlord wants a different strategy after marketing has begun, pause the instruction and obtain advice on the specific facts rather than quietly replacing the advert.

Before release, compare the portal feed, agency website, window card, email campaign and social copy. Syndication can turn one approved record into several public versions; an old price left on one channel makes the evidence harder to explain even if the main portal is correct.

Use enquiry and viewing scripts that do not create an auction

Staff can explain the application process, viewing timetable and selection criteria. They should not say that another applicant has offered more, ask for a “best and final” rent, or hint that paying above the listed amount will improve somebody's prospects. GOV.UK says a breach can occur where conduct leads a person to believe they need to bid above the advertised price.

Busy viewings and several applications are common. What staff say next matters. Use a direct script: the rent is the amount in the advert; the agency will not consider a higher figure; applications are assessed using the stated, lawful criteria. Managers should approve this wording for phone calls, viewings and follow-up messages rather than leaving negotiators to improvise.

Keep affordability and suitability decisions distinct from rent negotiation. The agency may need income evidence, references, Right to Rent checks and the landlord's final instruction, but none of those steps requires applicants to compete on rent. Apply the same published process to each applicant and record any exception.

Handle an unsolicited higher offer without accepting it

An applicant may offer more without being prompted. The official guidance gives an example where a landlord accepts such an offer and the council finds a breach even though the landlord did not invite it. The acceptance is enough.

Give staff a simple route: capture the original message, do not amend the rent, send the approved response, and refer the application back to the advertised figure. The record should show that the agency did not invite the offer and did not use it to pressure anyone else. Avoid celebratory replies or vague wording such as “we'll put that to the landlord”, which can look like the higher amount remains in play.

The applicant can still be considered on the same basis as others at the advertised rent if the agency's process allows. Make the reset explicit. If the applicant will only proceed at the higher figure, do not convert that proposal into the tenancy rent.

Lower offers and genuinely different propositions

A prospective tenant may offer less than the advertised rent. The council guidance includes an example where a landlord accepts a lower offer and finds no rental bidding breach. Record the amount and the landlord's decision in the ordinary offer file.

A genuinely different offering can carry a different advertised price. GOV.UK gives furnished and unfurnished versions of the same property as an example, where the difference is real and each version has its own price. The file should show the changed terms, not merely a relabelled route to a higher rent for the same letting.

Put a rent ceiling into the offer and tenancy workflow

Store the advertised amount against the marketing instruction and flag any higher offer when it is logged. Before the tenancy is issued, compare the agreed rent with the stored figure and require a recorded review if they do not match.

That check should also cover manual drafts and data passed between systems. A compliant portal advert does not help if a negotiator later types a higher rent into the tenancy agreement. Keep an immutable snapshot or export of the advert because live listings disappear or change after a property is let.

Keep the evidence a council is likely to ask for

Councils enforce the rental bidding rules. GOV.UK says an investigation may seek the original advertised price, messages or recordings that show what was said, the tenancy agreement and statements from the people involved. A council decides a civil case on the balance of probabilities, so a dated operational record matters.

Keep evidence proportionately and in line with the agency's data-retention policy. A focused file should contain the approved price, the adverts, relevant applicant communications, the decision record and the final tenancy, connected by a property and marketing reference.

A first breach can attract a civil penalty of up to £7,000. The council guidance also explains additional penalties for repeating the same type of breach within five years. Agencies should record any complaint or final notice centrally because a later letting at another branch or property may still matter.

Audit the hand-offs, not only the advert

Sample recently agreed tenancies and trace each one backwards: tenancy rent, accepted offer, applicant messages and original advert. Look for amounts that changed, “best and final” wording, private messages outside the normal system and adverts without a specific price. Correct the process and preserve the original record rather than rewriting history.

Train landlords as well as staff. An agency can follow the rule and still face a difficult case if a landlord contacts applicants directly or asks the negotiator to relay a higher bid. Put the restriction into landlord onboarding and the marketing approval. Escalate an instruction that would require the agency to encourage or accept more than the advertised rent.

Fit the control into the wider lettings process

Rental bidding governs the price and offer conversation. The pending-money rules are separate. Our tenancy deposit guide explains security-deposit protection, while the Direct Debit rent collection guide covers rent after the tenancy begins. Do not use either process to disguise an amount above the advertised rent.

For the wider tenancy reforms, read the Renters' Rights Act guide and run the Renters' Rights readiness check. Agencies mapping the control across portal feeds, CRM stages and tenancy generation can also review Tekniti's agency operations approach. Keep the final selection and legal judgement with an authorised person; automation should surface the mismatch and retain the evidence.

This workflow concerns assured periodic tenancies in England. Wales, Scotland and Northern Ireland have different tenancy systems, and other discrimination and consumer-law duties may apply alongside the rental bidding rule. Check the primary law and take advice on disputed or unusual facts.
