Market rent against LHA
The Rental Value Calculator gives you an estimated market rent for a postcode and bedroom type, and sets it against the Local Housing Allowance: the maximum housing benefit a tenant in that Broad Rental Market Area can receive (frozen for 2026/27 at the 30th-percentile rate).
Coverage, top-up and summary
It shows how much of the rent LHA covers, the monthly top-up a benefit tenant would face, and a clear summary, with the area highlighted on a UK map. In lower-value areas LHA often covers most or all of the rent, which is why some investors look at benefits tenants as a long-term income source; in London it falls far short.
You can send the estimated rent straight into the Buy to Let Calculator to run the full numbers.
