The average UK rent increase in 2026, and why yours may look nothing like it

A rent increase notice has landed and the first thing you want is a reference point. Is this normal? Is everyone getting this? Are you being singled out, or is this just what 2026 looks like?

It is a fair question, and there is a real answer. But the honest version comes with a warning attached: the national average is a useful bit of context and a poor legal test. Knowing the average will tell you whether your increase is unusual. It will not tell you whether it is challengeable. Those are two different questions, and the second one is the one that decides whether you can do anything about it.

Here is both halves. This guide is for private renters in England on an assured periodic tenancy.

What the average actually is

The Office for National Statistics publishes the most reliable measure of UK rent inflation. Its most recent figures, published on 22 July 2026, cover the 12 months to June 2026.

Where	Annual increase	Average rent
UK	3.3%	£1,388
England	3.4%	£1,446
Wales	4.9%	£843
Scotland	1.3%	£1,012
Northern Ireland	2.9%	£877

So the headline number is 3.3% across the UK, and 3.4% in England. That is a good deal calmer than the 9% plus growth renters faced in 2022 and 2023, and the rate has been easing through the year. Zoopla currently expects rents to rise by somewhere between 2% and 3% across the rest of 2026.

If your increase is roughly in that 3% to 4% band, it is squarely in line with the national picture.

The average hides a very wide spread

Now the caveat. A single UK figure flattens some enormous regional differences.

In the 12 months to June 2026, private rent inflation in England ranged from 6.3% in the North East, the fastest in the country, down to 2.2% in London, the slowest. That is close to a threefold gap between two parts of the same country over the same period.

The irony is that London renters saw the smallest percentage rise while still paying by far the largest amount, at an average of £2,302 a month against £781 in the North East. A 2.2% rise on a London rent is a bigger cash increase than a 6.3% rise on a North East one.

So "is 5% a lot?" has no national answer. In London it would be well above the local trend. In the North East it would be below it.

Why the average is probably not your number

There is a second reason the headline figure may not match your experience, and it catches people out constantly.

The ONS figure measures all private tenancies, including the many renters whose rent did not move at all during the year. Averaged across everyone, including the unchanged, the number comes out modest. But if your landlord has not raised your rent since 2023 and has now decided to catch up in one go, you are not experiencing the average. You are absorbing three years of it at once.

Advertised rents tell a different story again, because they show what landlords are asking for homes available right now rather than what existing tenants are paying. Our own figures, sampled from live listings in early August 2026, show the gap clearly:

Town or city	Average advertised rent
London	£2,790
Oxford	£2,322
Bournemouth	£2,185
York	£1,639
Newcastle	£1,454
Reading	£1,321
Southampton	£1,176
Leicester	£1,053
Liverpool	£925
Hull	£791

London asking rents average £2,790 against the ONS all tenancy figure of £2,302. Neither number is wrong. They are measuring different populations, and the difference between them is roughly the price of having moved recently. You can see the full set on our average rent by town pages.

The bit that actually decides your case

Here is where the averages stop being the point.

England has no cap on private rent increases. There is no percentage your landlord must stay under, no formula tied to inflation, and no rule that says a rise must be reasonable in the abstract. What the law does say is that a rent increase must not take you above the open market rent for your property, which is what your home would realistically let for today if it went back on the market. That is the test in section 14 of the Housing Act 1988, and it is the only test a tribunal applies.

Which means both of these are true, and both surprise people:

• A large increase can be perfectly lawful. If your rent has sat untouched below market for years, a 12% rise that lands at market rent is not challengeable on the amount. The tribunal is not asked whether the jump was kind, only where the new figure sits.
• A small increase can be challengeable. If you were already paying above the going rate, even a 3% rise takes you further above market. The percentage looks unremarkable. The figure is still too high.

This is why comparing yourself to the national average can quietly mislead you in either direction. It can talk you out of a good challenge because your increase "only" matches inflation, or into worrying about a large increase that a tribunal would wave through.

The number that matters is not the size of the rise. It is where the new rent lands against comparable local properties.

What to do with your own notice

Three practical steps, in order.

Benchmark the new figure, not the jump. Find three to five genuinely comparable listings nearby: same number of bedrooms, similar property type, similar area, currently available. Where does your proposed rent sit against them? If it is at or below, the amount is likely defensible. If it clearly overshoots, you have something to work with. Our rent calculator is a quick way to get a starting benchmark for your area.

Check the notice itself is valid. This is the step people skip, and it is often the strongest ground of all. Since 1 May 2026, a Section 13 notice on the correct form is the only lawful route to raising rent on an assured tenancy in England. Rent review clauses and privately agreed variations no longer work, even if you said yes. If the notice has the wrong dates, the wrong form, too little notice or the wrong details, the increase may not be valid at all, regardless of whether the amount was fair. There is more on this in our guide to Section 13 rent increases and on how much your landlord can increase rent.

Mind the deadline, and keep paying. If you want to challenge the amount, you must apply to the First-tier Tribunal before the date the new rent is due to start. Miss it and the increase takes effect. While a challenge is running, keep paying the old, undisputed rent so no arrears build up. Since 1 May 2026 the tribunal cannot set your rent above the figure your landlord proposed, so the proposed rent is your worst case. There is no fee to apply.

The short version

The average is 3.3% across the UK and 3.4% in England, with a genuine range from 2.2% in London to 6.3% in the North East. Use that to understand whether your increase is unusual. Then set it aside, because your landlord is not bound by the average. They are bound by the market rent for your home, and that is the only figure worth measuring your notice against.

If you are not sure where yours lands, a free check on your notice will tell you whether there are grounds worth pursuing, on the amount or on the paperwork, before the deadline passes.
