Rental Bidding Is Now Illegal: UK Tenant Rights

The law is specific. Under the Renters' Rights Act 2025, a landlord or letting agent must advertise a clear, fixed asking rent. That number is not a starting point for negotiation. It is the price.

Once the asking rent is published, here is what the law prohibits:

• Inviting tenants to offer above the advertised figure
• Encouraging tenants to outbid each other
• Accepting an offer that exceeds the advertised rent
• Using vague language in listings that implies higher offers are welcome

The third point matters as much as the first two. A landlord who passively accepts a higher offer because a tenant volunteered one is still breaking the law. The obligation is on the landlord and agent to refuse it, not just to avoid asking for it (Whitegates, 2026).

The listed price is the price. There is no room to bid above it.

This shifts the entire dynamic of competitive rental markets. When ten people apply for the same flat, the landlord now has to choose between applicants on grounds other than who will pay the most. References, financial stability, and rental history become the legal basis for selection (Newton Fallowell, 2026). That is a different kind of competition, and a fairer one.

Informal bidding wars were not a quirk of a tight market. They were a structural advantage for landlords and a tax on tenants who could least afford it.

Consider how it worked. A landlord lists a property at £1,600 per month. Twelve people express interest. The agent calls each one and mentions, casually, that 'others have expressed interest at a higher level.' Some applicants walked away. Others, desperate not to lose the flat, offered £1,700, £1,750, £1,800. The landlord took the highest bid, and the advertised price became meaningless.

The people who could absorb that extra cost were, almost by definition, the wealthiest applicants. Everyone else either overstretched or lost the property. The advertised rent stopped being a signal of what you'd actually pay and started being a floor that the market would push above.

There are no published figures yet on how much the ban has moved average rents in contested markets, but the mechanism is clear. Removing price competition from the selection process means the advertised rent has to reflect what the landlord actually expects to receive. That is a meaningful change in how rental markets are supposed to function.

The ban also protects tenants from a subtler pressure: the feeling that you need to lock in a higher rent to 'secure' the property before signing a tenancy agreement. That kind of verbal commitment to above-asking rent was always legally murky, but it happened. Now it is off the table.

The ban on bidding does not mean landlords have to take the first applicant. They can still choose between people. They just cannot use price as the deciding factor.

Under the framework that has emerged since the Renters' Rights Act 2025 took effect, landlords are expected to use documented, objective criteria to select tenants. Northwood UK, a letting agent network that has published compliance guidance, describes this as a 'fair, documented process' that landlords can defend if challenged (Northwood UK, 2026).

In practice, that means assessing things like:

• Employment status and income verification
• Previous rental references
• Length of desired tenancy
• Move-in timeline

A landlord can prefer an applicant who wants a two-year tenancy over one who wants six months, if that suits the landlord's situation. What they cannot do is justify selecting a tenant on the basis that they offered £50 per month more.

For tenants, this matters. If you apply for a property at the advertised rent and are turned down, you now have a clearer basis to ask why. A landlord selecting on price is no longer making a lawful decision. If you believe a landlord is still running a hidden bidding process, document every communication. Keep the listing screenshot, save any messages from the agent, and note any verbal suggestions to offer more.

The Renters' Rights Act 2025 gives tenants a range of new protections worth reading in full, including changes to eviction rules and rent increases.

The ban is clear on paper. In practice, some agents will test the edges of it, at least for a while.

The most obvious breach is an agent telling you directly that another applicant has offered above the advertised rent and asking whether you want to match or exceed it. That is illegal. Tell them so, and put it in writing.

Subtler versions are harder to identify but still covered by the law. Watch for:

Vague listing language. Phrases like 'offers around £X' or 'guide price of £X' in a rental listing imply flexibility upward. The law requires a fixed, specific rent figure. 'Offers around £1,500' is not a fixed rent. Document it.

'Best and final offer' requests. This is the residential sales tactic imported into lettings. An agent asking you to submit your 'best offer' for a rental property is inviting above-asking bids. This is prohibited (Whitegates, 2026).

Pressure calls. An agent calling to say another applicant has 'gone further' without specifying what that means is nudging you toward offering more. This is hard to prove unless you save the call notes or follow up in writing to ask what they mean.

If you encounter any of these, your first move is to respond in writing, asking the agent to confirm the asking rent is the fixed rent and that no offers above it will be accepted or considered. Many agents will correct course immediately when they see the question in writing. If they don't, that written exchange becomes evidence.

The Renters' Rights Act 2025 bans the practice, but enforcement is not automatic. You have to take a step.

The most direct route for tenants who have already signed a tenancy at above-asking rent because they felt pressured is to consider whether a complaint to a relevant authority is appropriate. Trading standards bodies handle consumer protection complaints about letting agents. The Private Rented Sector Landlord Ombudsman, which becomes mandatory for landlords under the Renters' Rights Act, is another avenue for formal complaints.

Before any of that, document what happened. Screenshot the original listing with the advertised rent. Save every message from the agent. Write down the date and approximate content of any phone calls where a higher offer was suggested. That evidence base is what turns a grievance into a claim.

For the letter-drafting step, Remedy Legal can help. Remedy is an AI-powered legal platform built for tenants facing exactly these situations. You describe what happened, and Remedy drafts a formal letter to your landlord or agent citing the relevant legislation. There is a free tier with no card required that gives you an instant assessment of your situation.

If you want to understand the broader picture of what the Renters' Rights Act 2025 means for claims you might already be entitled to, the Renters Rights Act 2025: What Tenants Can Claim guide covers this in detail.

The bidding ban covers the moment of letting. A separate part of the Renters' Rights Act 2025 covers what happens once you are in the property.

Landlords can still raise your rent. But the process is now more tightly controlled. A landlord who wants to increase your rent must use a formal Section 13 notice, giving you at least two months' written notice. You have the right to challenge that increase at a First-tier Tribunal if you think it is above the market rate for the area.

This matters in the context of bidding wars because some landlords who previously relied on tenants bidding up to above-market rents may now try to recover that 'lost' income through larger annual rent increases. If your landlord serves a Section 13 notice for an increase that seems out of step with local rents, you can push back. The tribunal will assess the market rate, and you are not obligated to accept the increase before the tribunal date.

The process for challenging a rent increase is set out in detail in our guide on what to do when your landlord wants to raise your rent.

The connection between bidding bans and rent increase controls is not coincidental. Both sit within the same framework: the Renters' Rights Act 2025 aims to make the price you pay for your home predictable at the start of a tenancy and contestable during it.
