Ready to challenge your rent increase?

Receiving a rent increase notice can feel overwhelming, but you're not powerless. English law gives tenants clear rights to challenge rent increases, and many tenants who push back end up paying less than their landlord originally proposed. There are two distinct ways to challenge a rent increase. First, the notice itself may be legally defective -- if your landlord didn't follow the rules set out in Section 13 of the Housing Act 1988, the increase simply cannot take effect. Second, even with a valid notice, you can apply to the First-tier Tribunal to argue the proposed rent is above market rate. Many tenants don't realise they have these options, or assume the process is too complicated. In reality, checking a notice for errors takes just a few minutes, and applying to the Tribunal costs just £47, with Help with Fees available if you are on a low income.

Before anything else, check whether your landlord's Section 13 notice complies with the legal requirements. Common errors that invalidate a notice include: Using the wrong prescribed form -- since 1 May 2026, when the Renters' Rights Act 2025 came into force, the notice must be on Form 4A. The older Form 4 is no longer valid for new notices. Giving insufficient notice -- your landlord must give at least two months' notice, the minimum for all tenancies since 1 May 2026. Setting the start date too early -- the new rent cannot begin less than a year after your last increase or tenancy start. If the notice is invalid, your landlord must serve a fresh, correct notice before any increase can apply. RentSOS checks all of these rules automatically -- you just answer a few questions about your tenancy and notice.

If the notice is valid, the next question is whether the proposed rent is reasonable. The First-tier Tribunal assesses rent increases based on what a willing tenant would pay for your property on the open market, ignoring any improvements you've made. RentSOS compares your proposed rent with median rents for similar properties in your postcode area. If the data suggests your landlord is asking for above-market rent, that's a strong basis for a Tribunal application. Our negotiation pack includes local market data that you can reference directly in your Tribunal application or your letter to the landlord. Having concrete figures strengthens your position significantly.

Many rent increase disputes are resolved without ever reaching the Tribunal. A well-written letter to your landlord, citing specific legal issues or market evidence, often leads to a negotiated outcome. RentSOS generates a personalised letter that references the exact problems found with your notice and includes local market data. The tone is firm but professional -- exactly what's needed for an effective negotiation. If your landlord doesn't respond or won't negotiate, you still have the option to apply to the Tribunal. The important thing is that you've started from a position of knowledge and strength.

If negotiation doesn't resolve the issue, the First-tier Tribunal (Property Chamber) is your next step. The application is made on Form MR1 with a £47 fee (the Help with Fees scheme can cover it), and the process is designed to be accessible without a solicitor. You must apply before the rent increase start date shown on your notice. The Tribunal will consider evidence from both sides and set a fair market rent. They cannot set the rent higher than what your landlord proposed, so there's no risk of the process backfiring. RentSOS provides a pre-filled Tribunal application template as part of the negotiation pack, saving you time and ensuring all the key information is included.
