In short: Subletting means letting all or part of your rented home to someone else, who becomes your tenant. Most private tenancies forbid subletting without the landlord's written consent; doing it anyway is a breach and can lead to possession proceedings. Taking a lodger who shares your living space is different from subletting a self-contained part, but still usually needs permission. Subletting a whole council or housing association home and moving out is a criminal offence. Fraser Bond can advise landlords on consent requests and manage properties to prevent unauthorised occupation.
