Is my rent increase fair?

If your landlord has proposed a rent increase, you are probably trying to answer one urgent question: is the new rent reasonable?

The clearest way to check is to compare the proposed rent with the open market rent for similar homes nearby. The percentage increase matters for your budget, but it is not the main evidence question. A large increase can sometimes reflect the market if the rent has been low for several years. A smaller increase can still be too high if the current rent is already above similar local homes.

Check your rent increase for free using the UpRently Rent Rise Checker. It compares the proposed rent with local market evidence where suitable comparable data is available.

What fair means when rent is increased

For private renters in England, the official question is whether the proposed rent is above the open market rent. This means the rent a landlord might reasonably expect if the same home was available to rent on the open market now.

That definition matters because it shifts the question from opinion to evidence. It is not simply about whether the increase feels high, whether the landlord’s costs have gone up or whether a percentage looks reasonable. Those points may matter to you, especially for affordability, but the market rent question is about what similar homes are renting for.

A useful comparison needs to start with the right market. A room in a shared house, a studio flat, a two-bedroom flat and a three-bedroom semi-detached house are not the same market. A two-bedroom flat in a town centre may not compare well with a two-bedroom flat several miles away if transport links, parking, condition or demand are very different.

This is where many people get stuck. Search results on property websites can be helpful, but they are not always enough on their own. You need to look at whether the examples are genuinely close to your home. The more differences there are, the less reliable the comparison becomes.

How to compare your home with other homes

Start with the details that usually have the biggest effect on rent:

• the property type
• the number of bedrooms
• the local area
• the condition of the home
• outdoor space
• parking
• furniture
• whether bills, Council Tax or services are included

A home with a garden, parking, recent refurbishment or good energy performance may achieve a higher rent than a similar-sized home without those features. A property in poor condition, above a shop, on a busy road or further from transport links may achieve less.

You also need to check what is included in the rent. If one advertised rent includes bills and another does not, the headline figures are not comparing the same thing. A rent that includes Council Tax, internet or utilities may look higher but could still be reasonable once those included costs are considered.

Think of comparables as evidence with a strength rating. A very strong comparable is close by, has the same number of bedrooms, is the same type of home and is in similar condition. A weaker comparable may still be useful, but you should explain the differences. For example, a two-bedroom flat with parking is not the same as a two-bedroom flat without parking.

Why percentage increases can mislead

Online discussions often focus on whether a landlord can increase rent by a certain percentage. This can be misleading.

A 20% increase may sound excessive, but if the rent has not changed for several years, the proposed rent may still be close to the current local market. A 5% increase may sound modest, but it could still be above market if similar homes nearby are cheaper.

Percentage is still useful for understanding affordability. If the proposed rent would make the home unaffordable, that is an important personal and financial issue. But if you are deciding whether the rent looks fair against the official market rent question, you need comparable evidence.

Example: if your current rent is £900 and the landlord proposes £1,080, the increase is 20%. That feels significant. But the next question is what similar local homes are advertised for. If similar homes are usually around £1,050 to £1,100, the increase may be easier to evidence. If similar homes are usually around £950 to £1,000, the proposed rent may need closer checking.

What to check before deciding what to do

If you have been given a Form 4A rent increase notice, officially called “Landlord’s notice proposing a new rent for assured tenancies in the private rented sector”, read it carefully.

Check the proposed new rent, the date it is due to start and whether the landlord has given enough time before that date. GOV.UK says private landlords in England must generally use Form 4A and give at least two months’ notice when using the section 13 process.

This guide does not check whether your notice is valid. That is a legal question and may depend on your tenancy and the details of the notice. The practical point is that the date matters. If you want to challenge the proposed rent through the official market rent process, you need to act before the proposed new rent starts.

If you are unsure, get advice quickly. Waiting too long can reduce your options.

How UpRently can help

UpRently is designed to reduce the evidence problem.

The UpRently Rent Rise Checker asks for the information needed to compare the proposed rent with local market evidence. This includes the current rent, proposed rent, postcode, property type and number of bedrooms. Where suitable comparable data is available, it gives a result that shows whether the proposed rent looks close to the local market or above it.

It also shows a confidence rating. This is important because rent evidence is not always equally strong. If there are several good comparables, the result is more useful. If there are too few comparables, the honest answer may be that there is not enough data to give a reliable indication.

The Evidence Pack gives you a clearer record of the comparables, the method used and the evidence summary. It does not decide your case or tell you whether to challenge. It helps you understand the local market and keep the evidence in one place.
