Most tenancy agreements say you cannot sublet without your landlord's permission. Here is what is allowed, and the risks if you don't follow the rules.

In short
Usually not without the landlord's permission. Most tenancy agreements ban subletting. Or they ask for written permission first. Subletting without it risks eviction. Social tenants face stricter rules still. Here is how it works.
What your agreement usually says
Most private tenancy agreements hold one of these:
- A clear ban on subletting
- A duty to ask the landlord in writing. Permission must not be unreasonably refused
- Limits on overnight stays, or on taking in a lodger
Check your tenancy agreement carefully.
Social tenants: stricter rules
- Subletting your whole home is usually a crime. The Prevention of Social Housing Fraud Act 2013 makes it so
- Fines, prison, and a lost tenancy can all follow
- Some social tenancies allow one lodger. The landlord must agree first
What to do if you want to sublet
- Read your tenancy agreement.
- Ask the landlord in writing, even where the agreement stays silent.
- A social tenant should never sublet without proper permission.
