Overview

Subletting creates a new tenancy between the tenant and a sub-tenant while the original tenancy continues. Most agreements prohibit it without consent; unauthorised subletting is a breach of contract, a possession ground, and can create an unlicensed HMO or invalidate insurance.

Legal requirements

  • Unauthorised subletting of a whole social or private home may also be a fraud offence.
  • Consent, if given, should be in writing and conditional.

Practical guidance

  • Check listings sites for your address if you suspect short-term subletting.
