Can Landlords Still Increase Rent in 2026? The New Rules Explained

The short answer

Can landlords increase your rent in 2026? Yes. Are they free to do it as often or as aggressively as they want? No, and that is genuinely new.

The new rules are simple at the top level: once per twelve months, with two months' written notice, and the new rent must be in line with the local market. That last bit is where most of the arguments live.

The once-a-year rule

Rent can only be raised once in any twelve-month period. If your landlord pushed it up last September, they cannot touch it again until next September — full stop.

This is huge if you ever lived through a tenancy where the rent moved twice in a year. You can now plan your budget with confidence. You know what your housing costs will be for the next twelve months once a notice has landed.

Two months' written notice — properly served

Your landlord must give you formal, written notice — not a casual text or a comment at the door. The notice must use the correct form (a Section 13 notice in most cases) and give two clear months before the new rent kicks in.

If they get the form wrong, the date wrong, or the notice period wrong, the increase is not valid. You can ignore it and keep paying the old rent until they redo it properly. That's not a technicality — it's your protection.

The 'fair rent' clause — and where it gets messy

The increase has to be in line with market rate for similar local properties. That sounds clear and isn't. Market rate is a range, not a number, and reasonable people can disagree about it.

If your landlord raises by 15% but similar nearby flats have only risen 5%, that's a defensible challenge. If the whole street has shot up, your landlord has a point. The First-Tier Property Tribunal exists exactly to settle the cases in between.

What you can actually do

Don't accept a notice on autopilot. Three steps.

First, check the market. Search Rightmove, Zoopla and OpenRent for the last sixty days of let agreed (not asking) prices on similar properties in your postcode. Save the comparables.

Second, do the maths. Is the increase 3%, 8%, 15%? A small percentage rise on a high rent is still a lot of money — but the tribunal cares about the rate relative to local market movement.

Third, write back. Calmly explain why you think the increase is above market and propose a number you'd accept. Many landlords will negotiate rather than risk a tribunal that could fix the figure lower.

The market-rate defence

Be fair to your landlord. If the local market has genuinely moved — and in many areas it has — a reasonable increase is legal and proportionate. The Act isn't rent control. It stops abusive rises, not all rises.

If your evidence shows the proposed rent is roughly in line with what other landlords are achieving in your area, you may not love it, but you'll struggle to challenge it.

Challenging an unfair increase

If you believe the increase is unfair, you can refer the notice to the First-Tier Property Tribunal before the new rent takes effect. It's a relatively low-cost process; you don't need a lawyer.

Crucially, your landlord cannot retaliate. Section 21 'no-fault' evictions are gone. You can challenge without fearing the door.

If the answer is no — you're not trapped

Sometimes the increase is legal but still bad for you. That's the moment to remember the new market reality: you can post on RentRequests, describe what you need at the budget you can actually afford, and let landlords come to you.

You don't have to stay somewhere that no longer works.
