LLCR

LLCR is a private compliance register for landlords and letting agents in England. It keeps every certificate, deadline, notice and proof of service for each property in one tamper-evident record, so the evidence exists in order when a tenant, a council or a court asks for it. It is not a government service and is separate from the Private Rented Sector Database and any other statutory register.

The tools answer one question each. LLCR keeps the certificates, deadlines and notices for every tenancy you hold.
