RentProof – UK Rent Deal Data

Gives UK tenants real agreed-rent data to negotiate with letting agents

Problem

A user was asked for a 30% rent increase but found tenants only see asking prices, not actual agreed deals, while agents see transactions across their whole portfolio. The information asymmetry makes it easy for agents to justify big increases.

Solution

Aggregate public UK rental data, Land Registry records, and anonymized user-submitted rents into a searchable agreed-rent reference by postcode, property type, and size. Users generate a rent-reasonableness report for negotiations and subscribe to alerts for their target area.

Users

UK renters, international students, tenants negotiating renewals or increases, and small landlords.

MVP

Input postcode and property type to see recent public rent ranges; anonymous user submissions of actual rents; generate a shareable rent-reasonableness PDF; price-drop alerts for target areas.

Revenue

Free basic ranges; Pro subscription at £4/month for detailed reports, alerts, and comparisons; affiliate deals with moving and insurance services.

Why now

UK rental data is increasingly open, and public APIs are affordable; tenant awareness is rising while agents still rely on information gaps.
