Rent calculator: check the average rent for your area

The open-market rent for your home is what it would realistically let for if it were advertised today: same property, same condition, a willing landlord and a willing tenant. There is no official register of market rents, so the figure is built from comparables, meaning similar properties in your area and what they are advertised for.

That is what the checker above does. It takes current asking rents for listings matching your bedroom count (and property type, if you set one) within a radius of your postcode and averages them. The sample size is shown with every result so you can judge how much weight to put on the number: an average built on 40 nearby listings is far stronger evidence than one built on 5.

Several things move market rent beyond location and size: condition (a tired kitchen, single glazing or damp all push it down), what is included in the rent (furniture, appliances, parking, bills), and energy efficiency, since a poor EPC rating means higher running costs. Our guide to how much a landlord can increase rent covers the market ceiling in detail.

The averages above are asking rents, and asking rents are the start of the negotiation, not the end. Homes often let for less than the advertised figure, and a listed price is not proof that anyone paid it. If your rent sits a little below the local asking-rent average, that is entirely normal.

Sitting tenants also tend to drift below the market over time. Landlords reprice a property most aggressively between tenancies, when it is empty and advertised, while rent inside an existing tenancy moves more slowly. So a long-standing tenancy at below-average rent is common, and it is not something a landlord can correct in one jump without following the legal process.

The comparison worth acting on is the other direction. If your rent is meaningfully above the average asking rent for similar homes nearby, you are paying more than the market would charge a new tenant, and that is worth investigating. Our is your rent too high guide walks through the warning signs.

First, nothing changes automatically. Being above market does not entitle you to a rent cut, and it does not oblige you to keep quiet about it either. What it gives you is evidence, and evidence is what moves negotiations.

Gather the facts: the average from the checker above, plus 3 or 4 live listings for genuinely comparable homes near you. Then raise it with your landlord in writing, briefly and factually. Renewal time is the natural moment, because a landlord weighing your request against the cost of a void month and re-letting fees has a real incentive to keep a reliable tenant. Many will settle for holding the rent flat, or a smaller figure, rather than lose you.

If instead of negotiating your landlord responds with a formal rent increase notice, the law is on your side more than you might expect, which is the next section.

Since 1 May 2026, under the Renters’ Rights Act 2025, rent on an assured periodic tenancy in England can only rise through a Section 13 notice on Form 4A. Rent review clauses in tenancy agreements no longer have effect. The increase can happen at most once a year, you must get at least 2 months’ notice, and the new rent must start on the first day of a rent period.

If the notice is valid but the proposed figure is above the open-market rent, you can apply to the First-tier Tribunal on Form MR1 before the start date on the notice. The fee is £47, there is no hearing fee, and the tribunal cannot set a rent higher than the figure your landlord proposed, so challenging carries no risk on the rent itself. The market comparison from the checker above is exactly the kind of evidence the tribunal considers.

Throughout any challenge, keep paying your current rent in full and on time. Arrears create a separate and more serious problem, and a clean payment record strengthens your position.

The affordability calculator above uses the long-standing budgeting guideline that rent should take no more than around 30% of your monthly take-home pay. At that level, most households still have room for bills, food, travel, debt repayments and some saving. Between 35% and 40% is a stretch zone: workable if your other fixed costs are low, uncomfortable if they are not. Above 40%, most advisers would describe you as rent-burdened.

Treat it as a guideline, not a rule. In London and other high-rent areas, plenty of renters pay 40% or more because the alternative is a longer commute or a smaller home; that is a trade-off, not a personal failure. And remember rent is not your whole housing cost: council tax, energy, water and contents insurance come on top, so two homes at the same rent can carry very different monthly totals.

Market figures come from PropertyData, which aggregates current asking rents from Rightmove, Zoopla and OnTheMarket for listings near the postcode you enter.
