How Often Can My Landlord Increase The Rent In 2026?

Your landlord wants to put the rent up. Since 1 May 2026 there is exactly one lawful way to do that, and a fairly short list of things that make it invalid.

Here's what they have to do, what you can do about it, and the tribunal route almost nobody uses.

The short version

• Once a year, and never in the first twelve months of a tenancy.
• Two months' notice minimum, on the prescribed form.
• No rent review clauses. A clause in your agreement saying rent rises automatically every April no longer works.
• You can challenge it at tribunal, free, if the proposed rent is above market rate.

The only lawful route

Since the Renters' Rights Act, a landlord raising the rent on an assured periodic tenancy has to use the statutory process. There is no other valid method.

That means:

1. The prescribed form. Not an email, not a letter, not a text saying rent goes up in April. Form 4A.
2. At least two months' notice before the new rent starts.
3. No more than once in any twelve month period.
4. Not during the first twelve months of the tenancy.

If any of those is missing, the increase isn't valid and you don't have to pay it. That's worth checking carefully rather than assuming, because informal rent rises by email were extremely common and habits take time to change.

What stopped working

Rent review clauses. Plenty of older agreements contain a clause saying rent increases by a set amount or by inflation each year automatically. Those no longer take effect. The statutory route is the only route.

Increases as leverage. Raising the rent to push out a tenant who complains is now much harder to make work, because you can challenge the amount and there's no Section 21 to follow it up with.

Fixed-term renewal negotiations. Fixed terms are gone. There's no renewal moment where a landlord can present a higher rent as the price of staying.

How much can they increase it by?

There's no percentage cap. A landlord can propose whatever they like.

What limits it is that the increase must be to market rate, and if you think the proposal is above what the property would actually let for, you can challenge it. That's the control, rather than a fixed ceiling.

In practice most landlords propose something defensible, because an unrealistic figure is likely to be reduced at tribunal and costs them the two months anyway.

Challenging an increase

This is free, and very few tenants do it.

You apply to the First-tier Tribunal (Property Chamber) before the new rent is due to start. The tribunal decides what the market rent for the property actually is, looking at comparable local properties.

Two things worth knowing before you do it.

The tribunal decides the market rent, not a fair rent. If the proposed increase is genuinely in line with the market, it will be confirmed. Challenging on the basis that you can't afford it, or that it feels like a lot, will not succeed.

Get your evidence together. Screenshots of comparable properties currently advertised nearby, at similar size and condition. Note anything about your property that makes it worth less than those comparables: no parking, poor EPC, outstanding disrepair.

That last point is important. If there are repairs outstanding, say so and evidence them. A property in poor condition is worth less on the open market, and that is directly relevant to what the tribunal is deciding.

Before you challenge, talk

Worth trying first, because it often works and it costs nothing.

A landlord facing a void period, re-letting costs and a new tenant of unknown quality has a real incentive to keep a reliable tenant. If you've paid on time for two years and never caused a problem, say so, and propose a figure you can manage.

Put it in writing, be specific, and be realistic. "I can do £900 but not £975" gets further than "that's too much".

Our guide on keeping a good relationship with your landlord is genuinely relevant here.

What to do when a notice arrives

1. Check the form. Is it the prescribed form, or an email?
2. Check the dates. At least two months, and not within twelve months of the last increase or the start of the tenancy.
3. Check the market. Look at what similar properties nearby are actually advertised at, today.
4. Decide quickly. A tribunal application has to be made before the new rent takes effect, so don't sit on it.
5. Keep paying the existing rent in the meantime. Arrears are a mandatory ground for possession at three months, and nothing about a disputed increase changes that.

That last one matters. Challenging an increase is not a reason to stop paying. Pay the old amount while the challenge is decided.

If you can't afford it either way

Talk to your landlord early, and check what you're entitled to. Universal Credit housing element, Discretionary Housing Payments and council hardship schemes all exist and go unclaimed.

Our guides on paying rent, saving money when renting and what renting actually costs cover the practical side. And if moving is the answer, staying or moving on weighs it up.

The short answer

Once a year, never in the first twelve months, two months' notice, prescribed form. No percentage cap, but you can challenge anything above market rate at tribunal for free.

Check the paperwork before you accept it, because an invalid notice doesn't take effect, and informal increases by email are no longer lawful however normal they used to feel.

And if your landlord handled a rent rise badly, or used one to push you out, put it on the record. It's the only way the next tenant knows.
