The Ban on Rental Bidding: What it Means for Landlords and Setting Compliant Market Rent

Defining the Illegal Practice

The ban on rental bidding practices is one of the main components of the new Renters’ Rights Act 2025. This legislation represents a fundamental change to how tenancies are negotiated in the UK. This ban is designed to eliminate the ‘silent auction’ environments that have historically forced prospective tenants to compete against one another, often pushing rent prices significantly above advertised rates.

Under the new legislation, the practice is clearly defined as illegal through two specific, prohibited actions that landlords and agents must not undertake:

Asking for rent offers that exceed the property’s initially advertised price.
Accepting rent offers that are higher than the price that was formally listed.

This means that properties must be advertised at a fixed rent, and landlords or agents must refuse offers above that listed figure. Encouraging or inviting tenants to bid higher will constitute a breach of the Act. The legislative trigger for this ban is the Renters’ Rights Act 2025, which, following Royal Assent, is scheduled to commence in its major phases from mid-2026.

Breaching these new affordability controls will not be without consequence. Landlords and letting agents found to be non-compliant will be open to civil penalties and fines, enforced by local authorities and Trading Standards. The government introduced this measure to foster a more transparent, predictable, and fair rental market for all.

Setting Compliant Market Rent (Pre-Advertising)

With the ban on rental bidding, the era of testing the market with an introductory price is over. The new legal environment, enforced by the Renters’ Rights Act 2025, makes diligent, accurate preparation before advertising a property an absolute necessity for compliance and maximising legal income.

The key compliant strategy for landlords and agents is straightforward advertising. You should advertise the absolute maximum rent you are prepared to accept for the property. If you receive an offer at this price, you must select a suitable tenant and proceed without demanding any further increase. Any attempt to solicit or accept a higher offer is unlawful.

This shift emphasises the importance of detailed pre-advertising market research. Landlords must undertake diligent comparative analysis to ensure the asking price is both accurate and robust. To achieve this, we strongly advise instructing a professional letting agent for a precise valuation. Framing this as a necessary compliance step is vital; a professional valuation helps avoid both:

Under-pricing, which tempts illegal bidding.
Over-pricing, which risks lengthy void periods.

Moving forward, transparency is a legal necessity. Agents must avoid all suggestive language, such as “offers over” or “rent negotiable,” and standardise their application processes to ensure selections are based purely on merit and suitability, not an ability to pay a higher rent.

How to Legally Adjust Rent (Post-Advertising)

The ban will alter the marketing process, but it does not remove a landlord’s right to value their asset accurately. A typical scenario is when a listing generates an unexpectedly high volume of offers at the advertised rate, suggesting the initial market price was underestimated.

If this occurs, the compliant strategy for a landlord is to implement a legal adjustment to the asking price. This is permitted only if no offers have yet been accepted by the landlord or agent. You will need to formally withdraw the property and re-list it at the revised rate.

Crucially, the increase must be justifiable by prevailing market conditions, and all new advertising must be clear, transparent, and state only the fixed price the landlord genuinely intends to accept. You must not simply take the highest private offer from the initial round.

Remember, the Act prohibits price competition, but it does not interfere with your right to choose a tenant based on lawful criteria such as references and suitability. Under the new law, you must reject even unsolicited offers that exceed the advertised rent.

Furthermore, once a tenancy is established, rent reviews are limited to one increase per year under the revised Section 13 procedure of the Housing Act 1988, requiring two months’ notice. This provides a clear, compliant pathway for managing long-term rental income growth, away from prohibited bidding practices.

Conclusion: Transparency and Compliance

The Renters’ Rights Act 2025 means rental bidding is now illegal, replaced by a statutory requirement for transparency and professional conduct in the rental market. This measure is not about restricting a landlord’s right to earn a fair return, but about protecting tenants from rent inflation driven by desperation rather than justifiable market value.

UK landlords and agents must now shift entirely towards setting an accurate, justifiable final price before marketing. The practice of testing the market or relying on bidding to determine value is over. To ensure legal compliance and maximise rental yield, the advertised price must be the highest rent you are willing to accept.

Navigating this new era requires expertise and a commitment to detailed, documented valuation. Don’t risk reputational damage or significant financial penalties by relying on guesswork.

Rental Bidding FAQs

Is the Ban on Rental Bidding already in effect?

The ban will come into effect once the Renters’ Rights Act 2025 is fully implemented in its main phase, which is expected in mid-2026. However, given the significant consequences of non-compliance, landlords and agents should now prepare and adjust their operational procedures to ensure a smooth transition and avoid inadvertently breaching the law.

Can a landlord accept a higher rent if the tenant offers it unsolicited?

No, this is strictly illegal. Under the new legislation, landlords and agents must reject all offers that exceed the property’s advertised fixed rent, even if the tenant initiates the offer without any prompting. The advertised price sets the non-negotiable legal maximum.

What penalties might I face if I accept a higher offer?

Breaching the rental bidding prohibition can lead to significant civil penalties and fines imposed by local authorities or Trading Standards. Beyond financial repercussions, non-compliance could also result in serious reputational damage and may even affect your ability to secure or retain a landlord licence in areas with licensing schemes.

Does this rule apply to HMOs and student leases?

Yes. The ban on rental bidding applies broadly to all private rental agreements that fall within the scope of the Housing Act. This means properties let as single residences, as well as Houses in Multiple Occupation (HMOs) and student tenancies, must all comply with the fixed-rent advertising requirement.

Can I adjust the rent after a tenancy has started?

You retain the legal right to review and increase the rent once per year. However, you must follow the correct statutory procedure (such as the revised Section 13 notice process), giving the tenant two months’ notice. You absolutely cannot solicit or encourage higher bids during the initial marketing or tenant selection process.
