Who can see your information

Verified landlords and agents

A verified landlord searching Letline sees a shortened renter name, such as first name and surname initial, together with search area, income, maximum rent, bedroom need, move date and document or credit-check status. Uploaded documents, email address, full postcode and Home Office share code are not shown in the search results.

A landlord may privately share a property and photographs with a chosen renter. If the renter accepts and requests a viewing, the landlord receives the information needed to handle that request. Full contact details are intended to be released only as the match progresses, rather than in the initial applicant search.

Renters

A renter sees property information and photographs privately shared with their account, together with viewing updates relating to that match.
