Why this exists
When you receive a rent increase letter, the landlord usually has all the information and you have very little. Listing portals are built for renters looking to move, not tenants weighing up whether to stay. The tribunal route exists, but most tenants never use it because the first step — proving the proposed rent is above market — feels too opaque.
RentCharter narrows that information gap. We turn what's already public (rental statistics, tribunal practice, tenant rights) into something practical: a free check, a printable evidence pack, and plain-English guides.
What we are
- Free, with no advertising and no commission.
- Independent — we don't take money from landlords or letting agents.
- Privacy-first — your figures stay in your browser.
- Open about uncertainty: every estimate shows confidence and source.
What we are not
- A regulated legal service. We don't give legal advice.
- A substitute for advice from Shelter, Citizens Advice, or a solicitor.
- A scraping operation. We don't copy listings from third-party portals.
Where the data comes from
For the MVP, RentCharter uses an indicative dataset built around publicly stated ONS Private Rental Market Statistics and VOA local authority private rents. Over time we plan to add:
- Tenant-submitted rents (with moderation).
- Uploaded tenancy agreements.
- Licensed listing snapshots.
- Letting agent submitted comparable evidence.
- First-tier Tribunal outcome data.
