The rental bidding ban: why the advertised rent is now a ceiling

A landlord advertises a flat at £1,300 a month. Three people want it. One of them offers £1,400 to get to the front of the queue. For years that was simply how a competitive rental market worked.

Since 1 May 2026, accepting that offer is unlawful.

The rental bidding provisions of the Renters’ Rights Act came into force in England as part of the first phase of the reforms, and they change the advertised rent from an opening position into a hard ceiling. This is one of the least discussed parts of the Act and one of the easiest to breach by accident, so it is worth setting out exactly what it requires.

What the rule actually says

There are two duties, and they work together.

First, you must publish an asking rent. Any written advertisement for a property to let has to state a specific amount of rent. “Rent on application”, “offers invited” and a bare price range are no longer sufficient. The figure has to be there, in the advert, before anyone views.

Second, you must not ask for, encourage, or accept an offer above it. All three verbs matter, and the third is the one people notice. The first two are where landlords and agents get caught.

“Encouraging” is broader than most people expect

You do not have to name a higher number to breach this rule. You do not have to run a formal sealed-bid process. Encouraging a higher offer is enough on its own, and it can be done in a single sentence at the end of a viewing.

Consider a few things that are said on viewings every week:

• “We have had a lot of interest — someone has already offered above the asking price.”
• “If you want to stand out, you might think about what you put forward.”
• “The landlord will go with the strongest offer.”

None of those name a figure. All of them invite a tenant to bid above the advertised rent, and that is the behaviour the provision is aimed at. If you would not be comfortable seeing the sentence written down next to the advert, it is probably the wrong sentence.

The safe position is straightforward: the advertised rent is what you are asking, and the conversation with an interested tenant is about whether they want the property at that figure — not about what they might pay to beat someone else.

The penalty, and who pays it

A breach carries a civil penalty of up to £7,000, and further penalties are available where a landlord or agent continues to breach the rule or breaches it repeatedly. This is not a one-off risk that can be priced in.

The part that catches private landlords is who carries the liability. The duty binds anyone acting directly or indirectly on the landlord’s behalf, which means an agent. If a letting agent encourages a higher offer on your property, the exposure is not confined to the agent. This is a good reason to know precisely how the people marketing your property talk to applicants, and to ask them.

The other half of the same rule: rent in advance

The bidding ban arrived alongside a restriction on rent in advance, and the two are easy to confuse.

Before a tenancy is signed, no rent in advance can be required at all. After it is signed, a landlord cannot require more than one month’s rent up front — or the equivalent of 28 days where the rental periods are shorter than a month.

Large advance payments were often used the same way bids were: as a way for one applicant to outrun another. Closing one route without the other would have achieved very little, which is why both changed together.

What this means if you let a property in Luton

In practice, the ban rewards pricing a property correctly at the outset. If the advertised rent is the most you can achieve, then the advert is no longer a negotiating position — it is the whole of your case. Set it too high and the property sits empty while you carry the cost. Set it too low and you have capped yourself for the length of the tenancy, with no lawful way to recover the difference from a keen applicant.

That makes an honest valuation more valuable than it used to be, and it makes an agent who inflates a figure to win your instruction considerably more expensive than they look.

How we let

We have never run a bidding war on a property, so this rule did not change how we work. Every property we market carries its rent in the advert, we agree that figure with the landlord before it goes live, and it is the figure the tenant pays. Applicants are assessed on affordability and references, not on who offers the most.

If you are letting a property in Luton or the surrounding area and you want a realistic figure rather than a flattering one, we offer a free, no-obligation valuation. Our fully managed service is 6% until 31 December, and 6% means 6% — there is no VAT to add.

Common questions

Can a tenant still offer more than the advertised rent?

A tenant is not prohibited from making the offer, but a landlord or agent cannot accept it, and cannot do anything to invite it. In practice the answer to an unsolicited higher offer is that the rent is the advertised figure.

Does this apply across the UK?

These provisions apply in England. Scotland, Wales and Northern Ireland have their own separate rules on rents and lettings.

Can I advertise a rent range instead?

No. The requirement is a stated amount of rent in the advertisement.

What if the property genuinely attracts several strong applicants?

You choose between them on the ordinary grounds — affordability, references, suitability, start date. What you cannot do is choose on the basis of who will pay more than you advertised.
