Free tools and plain-English guides for the most common UK rent questions.
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.
