Rent guarantee insurance is optional cover that may help with lost rent if a tenant stops paying, subject to the policy’s terms, and is often offered alongside legal expenses cover. Providers commonly require satisfactory tenant referencing, a written tenancy agreement, deposit compliance and prompt action when arrears arise. It may not cover every missed payment or periods when the property is empty, and waiting periods, exclusions, excesses and claim limits vary. Compare the total cost and conditions, read the policy wording carefully, and check details with an FCA-authorised provider; for tenancy or legal concerns, consider a solicitor regulated by the SRA.
