opndoor

Opndoor is a UK professional guarantor service helping tenants secure homes when they do not pass standard referencing or do not have a suitable guarantor.

We work with letting agents, landlords, Build to Rent operators, PBSAs and other property partners to provide a practical alternative to upfront rent, helping more applicants move forward while giving property providers greater confidence in rental income.

Through Opndoor, eligible tenants can access professional guarantor support backed by robust underwriting and insurance arrangements. The service is designed to sit alongside existing referencing and tenancy processes, making it easy for partners to refer applicants without changing how they operate.

Our aim is to make renting more accessible, reduce failed applications, and give property providers a compliant, practical way to support tenants who need additional backing.

Problems we solve for agents

Letting agents are losing viable tenants and taking on unmanaged risk. Under the Renters' Rights Act, agents can no longer ask for rent in advance or lean on informal safeguards, yet many good tenants still don't have a UK guarantor. Agents are left choosing between turning away decent tenants or exposing landlords to arrears risk. opndoor solves this by giving agents an insured, professional guarantor replacement: tenants pay a one-off fee for 12 months of insurance-backed cover, so agents can place more tenants confidently, stay compliant with the new legislation, and protect landlords from unpaid rent.
