Rental bidding

Rental bidding is the practice of inviting or accepting offers above the advertised rent from prospective tenants. It takes formal shapes, "offers over" listings, sealed-bid processes, requests for "best and final offers", and informal ones, where an agent hints that higher offers will be viewed more favourably. In a tight rental market, bidding wars have driven rents above what the property would otherwise achieve, creating a competitive dynamic that advantages tenants with the greatest financial flexibility and disadvantages those on fixed or lower incomes.

Rental bidding in England is now unlawful. Under Sections 55 and 56 of the Renters' Rights Act 2025, which came into force on 1 May 2026, landlords and letting agents are prohibited from inviting, encouraging, or accepting any rent above the advertised price.

What the law requires: the advertising obligation

When marketing a property to let, landlords and agents must now state a specific proposed rent, a fixed figure, in any written advertisement. This obligation applies to all online and printed listings, including property portals such as Rightmove and Zoopla, social media posts, emails, text messages, and printed particulars. The stated rent must be consistent across all platforms.

Simple "To Let" signs on boards or in windows do not need to show the rent. However, any listing that includes rent information, either online or printed, must state a fixed figure. Advertising with "price on application" (POA) for a residential let is a breach of the rules, because it withholds the proposed rent rather than stating it clearly.

Our guide to the 15 websites to advertise your rental property on covers the portals and channels where the stated rent must appear clearly.

What is and is not permitted once a rent is advertised

Once a property is advertised at a specific rent, that figure becomes the ceiling for any offer a landlord or agent may accept. Landlords may accept a lower offer than the advertised rent, there is no prohibition on negotiating down. They may not accept a higher one, under any circumstances.

Crucially, the prohibition extends to uninstructed higher offers from tenants themselves. If a prospective tenant voluntarily offers to pay more than the advertised rent, without any encouragement from the landlord or agent, the landlord is still prohibited from accepting it. MHCLG's implementation guidance is explicit on this point: the landlord bears the penalty, not the tenant, even where the higher offer was entirely unsolicited.

The rules also apply to indirect encouragement. Asking for "best and final offers", suggesting informally that competing applicants exist, or otherwise hinting that a higher bid will secure the property, all of these constitute a breach, even if no higher offer is actually received and the tenancy is eventually granted at the advertised rent. The Ministry of Housing, Communities and Local Government confirmed in its November 2025 guidance that "asking for offers, however obliquely worded," is deemed a request to pay higher rent.

Enforcement and penalties

Enforcement rests with local housing authorities, which apply a civil standard of proof, satisfied on the balance of probabilities, for the core advertising and bidding obligations. This is a lower threshold than the criminal standard and means that documentary evidence of the breach, such as email correspondence, portal listings, or WhatsApp messages, is sufficient to support a penalty.

Civil penalties are up to £7,000 for a first breach and up to £40,000 for a subsequent breach within five years. Breaches are also recorded on the Private Rented Sector Database once it launches from late 2026, making the enforcement history publicly visible.

Tenants also have a separate right of challenge. In the first six months of a new tenancy, a tenant may refer the initial rent to the First-tier Tribunal if they believe it was set above the local market rate, a route intended to act as a check against landlords inflating their advertised price to compensate for their inability to accept overbids. Landlords should retain evidence of the market-rate basis for their initial rent: comparable listing data, void period records, and the number of serious applicants who enquired.

August's rent tracking feature maintains a complete record of advertised and agreed rents per tenancy, useful evidence of market-rate compliance if a tenant exercises this first-six-months challenge right at the Tribunal.

Practical implications for landlords

The bidding ban changes the rent-setting process at its starting point. Landlords can no longer use the listing as an exercise in price discovery, accepting bids and selecting the highest. The advertised figure is now both the stated rent and the legal maximum, which means accuracy at the point of advertising matters more than it previously did.

Landlords with properties in high-demand areas should research comparable rents carefully before listing, using portal data, local agent intelligence, and their own historical void and enquiry records. Some landlords may set initial rents at the upper end of their assessed range to account for not being able to accept overbids, this is permitted in itself, but must be balanced against the risk of extending void periods and the tenant's first-six-months Tribunal challenge route.

The rental bidding ban sits alongside the rent-in-advance cap, both Phase 1 RRA provisions targeting the pre-tenancy period, both in force from 1 May 2026. The rental bidding ban governs the initial rent at the advertising stage. Rent increases after a tenancy has begun are separately regulated by the Section 13 notice procedure, which limits increases to once per year with two months' notice.

Frequently asked questions

Is rental bidding legal in England? 

No. Rental bidding, inviting, encouraging, or accepting offers above the advertised rent, has been unlawful in England since 1 May 2026 under Sections 55 and 56 of the Renters' Rights Act 2025. A landlord or agent who accepts a higher offer than the advertised rent, even if the tenant offered more without prompting, is in breach and faces a civil penalty of up to £7,000 for a first offence and up to £40,000 for a subsequent offence within five years.

Does the bidding ban mean landlords cannot charge what they want? 

Landlords remain free to set any initial asking rent they choose, there is no cap on what can be advertised. What is prohibited is using the listing as a price-discovery mechanism by accepting bids above the stated figure. The advertised rent is both the starting point and the ceiling for any offer the landlord may lawfully accept. Setting an initial rent that reflects the upper end of the local market range is permitted; testing the market by accepting the highest bid is not.

What counts as encouraging rental bidding? 

Encouraging bidding does not require explicit language. Asking applicants for "best and final offers", implying that competing applicants are bidding, hinting that a higher offer will be looked upon more favourably, or using "price on application" in online listings all constitute encouragement under the Act. MHCLG guidance confirms that a breach occurs at the point of asking, even if no higher offers are made and the property is let at the advertised rent.
