My landlord is encouraging a bidding war on the property — is that legal?

No. Bidding wars on rental properties are now illegal under the Renters' Rights Act 2025. A landlord must advertise a property at a fixed asking rent — and they cannot accept or encourage any offer above that amount.

This closes a loophole that was driving up rents in competitive cities. Previously, landlords (or their agents) would list a property at £1,500 and then quietly let multiple applicants know that whoever offered more would get it. That practice is now prohibited.

The asking rent in any written advertisement or offer must be the actual price. A landlord who accepts rent above that price faces a financial penalty of up to £7,000.

If you're in a viewing or application process and a letting agent suggests you offer more than the advertised rent to beat other applicants, that is also unlawful. You can refuse and report it.

Report a landlord or letting agent encouraging a bidding war to your local council's housing enforcement team. Keep screenshots or any written evidence of what was said — that makes the complaint much stronger.
