Search results for “how much can my landlord increase my rent” in England give the same misleading answer over and over: “Around 5%”, or “In line with inflation”, or “Whatever's reasonable”. None of these is the law. The actual answer is more useful, and more empowering, than the rumour.
The short answer
In England there is no statutory cap on the amount of a rent increase. Your landlord can ask for any figure they like. What the law caps is the process: how often they can raise it, how much notice they have to give, and what evidence they need if you challenge it at the tribunal.
The real ceiling is the local open-market rent. Under the Renters' Rights Act 2025 the First-tier Tribunal can only confirm or lower the proposed rent — it can't set it higher. So the landlord's figure is always the maximum, and good local evidence often pulls it down.
Why there's no cap (and what actually is capped)
England has chosen a market-led approach to rents rather than rent control. (Scotland, Wales and Northern Ireland have their own rules, which this article doesn't cover.) The Renters' Rights Act 2025 reform in England did not introduce statutory rent caps. So the substantive amount is uncapped.
What is capped is:
- Frequency: rent rises via Section 13 no more than once every 12 months — the new rent can't take effect within a year of the tenancy starting or the last increase.
- Notice: at least two months before the new rent starts (RRA 2025 — up from one month).
- Form: the increase must use the prescribed Section 13 notice form unless the tenant agrees in writing.
- Tribunal outcome: the First-tier Tribunal can only confirm or lower the proposed figure — it can no longer set a rent higher than what the landlord asked for. This used to be the chilling effect that stopped tenants challenging.

The Section 13 framework
Most tenants on a periodic (rolling, month-to-month) tenancy will see a rent rise via a Section 13 notice. The mechanics:
- Landlord serves a Section 13 notice on the prescribed form.
- The notice specifies the new monthly rent and the date it starts — at least two months from when it was served.
- If the tenant does nothing, the new rent takes effect on that date.
- If the tenant disagrees, they apply to the First-tier Tribunal (Property Chamber) before the new-rent date.
- The tribunal sets a rent equal to the open-market rent for the property, capped at the landlord's proposed figure.

How often rent can go up
Short answer: once every 12 months on a periodic tenancy via Section 13. For the full mechanics — including what happens if your landlord tries twice in a year — see our dedicated piece on how often a landlord can increase rent in the UK.
Under the Renters' Rights Act 2025:
- Periodic tenancies (private assured tenancies from 1 May 2026): once every 12 months via Section 13. Not negotiable, not contractually shortened.
- Rent review clauses: from 1 May 2026, a rent-review clause in your tenancy agreement can no longer be used to put the rent up — Section 13 is the route. If you're unsure how this applies to an older agreement, check with Shelter or Citizens Advice.
- Informal requests: an email or letter asking for more rent doesn't change the rent by itself. Keep paying your existing rent — paying the new figure without comment can be argued as agreement.
- By agreement: a tenant can always agree to a higher rent in writing, outside the Section 13 process. Don't. You give up the tribunal route by doing this.
Why ‘market rate’ is the real ceiling
The First-tier Tribunal determines what the rent should be by looking at what willing tenants are paying for similar properties in the area today. They look at:
- Comparable lets in the same postcode prefix (e.g. SW18, M14, BS1)
- The same property type (flat, house, studio, room)
- The same bedroom count
- The same level of furnishing and condition
- The state of repair
They don't consider:
- The landlord's mortgage or yield expectations
- How long you've lived there or how nice you've been
- Inflation, CPI, RPI, or wage growth
- What the landlord wants to charge a future tenant
This is why running a quick check on a tool like RentCharter's rent checker matters: you can instantly see whether your proposed rent sits below the lower quartile, around the median, or above the upper quartile of comparable lets. If it's within range, you're negotiating around the edges. If it's above the upper quartile, you may have a stronger case for a challenge.
Mid-tenancy and renewal increases
Two scenarios people confuse:
Mid-tenancy (your tenancy is rolling on indefinitely): the landlord uses Section 13. Two months' notice, max once a year, tribunal route available. This is the framework above.
“Renewal” (being asked to sign a new agreement at a higher rent): before 1 May 2026, landlords often used the end of a fixed term to propose a new figure. From 1 May 2026 private assured tenancies are periodic, so an increase you don't agree to has to go through Section 13. Signing a new agreement at a higher rent is agreeing to it — you don't have to, and knowing the Section 13 route exists is itself negotiating leverage.
What to do if the figure is too high
The playbook hasn't changed:
- Diary the dates. Note the new-rent date from the Section 13 notice — that's the tribunal deadline.
- Run a quick check at RentCharter to see where the figure sits in your local market.
- Reply in writing with a counter-offer based on comparable evidence. Our response template walks through it.
- If negotiation fails, apply to the First-tier Tribunal (form MR1) before the new-rent date. The fee is £47 for notices dated from 1 May 2026 (waived for earlier notices; Help with Fees can reduce it to £0), and no solicitor is needed. Our tribunal finder shows where and how.
The single most important fact post-RRA 2025: the tribunal cannot raise the rent above what your landlord proposed. So the risk of applying is limited: the worst case is usually the rent being confirmed at what the landlord asked for, plus the fee and your time. The best case is the tribunal cuts it materially. Its decision isn't backdated, so keep paying your current rent in full until it decides.
Frequently asked questions
Is there a legal cap on how much a UK landlord can raise rent?
No — England has no statutory cap on the amount of any single rent increase. The cap is procedural (you need a valid Section 13 notice for periodic tenancies, two months' notice, and only once every 12 months) and economic (the tribunal can lower a rent it thinks is above open-market rate). Scotland and Wales have separate rules — this article is England-specific.
How often can my landlord raise the rent?
Under the Renters' Rights Act 2025, no more than once every 12 months, via a Section 13 notice — the new rent can't take effect within a year of the tenancy starting or the last increase. From 1 May 2026 private assured tenancies are periodic, and rent review clauses in tenancy agreements can no longer be used to put the rent up.
Can the landlord raise the rent in line with inflation?
They can propose any figure they like — including 'inflation' or 'CPI plus 1%'. But 'inflation' isn't a legal benchmark in England. If you challenge at tribunal, the test is whether the proposed rent matches the local open market — not whether it tracked CPI. Sometimes inflation lags the market and the increase is conservative; sometimes inflation leads the market and the increase is excessive.
What's the most a landlord can increase rent at one go?
There's no statutory ceiling — but the practical ceiling is the local market rate. If the landlord asks for £2,000 and comparable lets in your postcode go for £1,500, the tribunal is likely to set the rent at or near £1,500 — it depends on the evidence. The landlord's number is the ceiling; the tribunal can only confirm or lower it under the Renters' Rights Act 2025.
Can my landlord evict me for refusing a rent increase?
Section 21 'no-fault' evictions were abolished from 1 May 2026 by the Renters' Rights Act 2025. A landlord now has to use Section 8 grounds for possession — and refusing or challenging a rent increase isn't a Section 8 ground. But other grounds exist, including rent arrears, selling the property or the landlord moving in, so keep paying your current rent in full while you challenge, and get advice from Shelter or Citizens Advice if you're worried.
How much can my landlord raise my rent every year?
Any figure they choose — there's no annual percentage cap in England. But the new rent has to be served via a Section 13 notice on the prescribed form with two months' notice, and the First-tier Tribunal can confirm or lower the proposed rent (never raise it) by reference to local open-market rent. So 'every year' is capped procedurally (once per 12 months) and economically (the local market), not by a fixed percentage.
What is the maximum rent increase per year in the UK?
There is no statutory maximum in England. Scotland, Wales and Northern Ireland have separate rules — this article covers England only. The practical maximum on a Section 13 increase is whatever the local open-market rent is for similar properties: anything above that, the tribunal is likely to lower if you challenge in time.
How much can they raise my rent in one go?
Whatever figure the landlord puts on the Section 13 notice — that's the ceiling. The tribunal can confirm it or set a lower figure if you challenge. There's no statutory percentage cap, but in practice the realistic ceiling is often around the local upper quartile of comparable lets.
