FAQ

Common questions from tenants

Still unsure? Read our full guide to rent increase rights.

Is RentCharter free to use?

Yes. RentCharter is a free public-interest tool. We don't require an account and we don't store your data on a server.

How is the local market rent estimated?

We use a calibrated indicative dataset based on publicly stated ONS Private Rental Market Statistics and VOA local authority private rents. Where you have a postcode in our sample, we match by postcode prefix, property type and bedrooms; otherwise we fall back to area name.

Can I challenge a rent increase that's only slightly above market?

It depends on your tenancy and the increase mechanism. For Section 13 notices on assured shorthold tenancies you can apply to the First-tier Tribunal. We always recommend speaking to Shelter, Citizens Advice or a solicitor before formally challenging.

Do you sell tenant data?

No. We don't sell, share or market your data. Your rent figures stay in your browser unless you choose to print or save them locally.
