Can I take in a lodger or sublet my rented home?
Short answer
Only if your tenancy agreement allows it or your landlord consents in writing. Most private agreements prohibit subletting without prior written consent, and doing it anyway is a breach giving grounds for possession. In social housing, unlawful subletting can also be a criminal offence.
The first distinction to get right is between a lodger and a subtenant. A lodger lives in the property alongside you, without exclusive possession of any part of it. Subletting means granting someone else the right to occupy all or part of the property while you remain the tenant — and it creates a landlord-and-tenant relationship between the two of you.
Private tenancies
Read your agreement. Most prohibit subletting without the landlord’s prior written consent; many are silent about lodgers, which can leave more flexibility where you continue living there. If you want either, ask in writing and keep the reply — verbal permission is worth very little in a later dispute.
Subletting without consent is a breach of the tenancy. Your landlord can serve a Section 8 notice relying on Ground 12 (breach of a tenancy obligation) and seek possession through the court, and may also apply for an injunction to stop the subletting.
Social housing: the criminal risk
For council and housing association tenants, unlawful subletting is not just a tenancy breach. Under the Prevention of Social Housing Fraud Act 2013 it is a criminal offence carrying an unlimited fine, any profit made can be recovered through a civil order, and you will almost certainly lose the tenancy. Landlords refer suspected cases to the police. If your circumstances have changed — you need to be elsewhere for work or care — talk to the landlord about a lawful option instead.
Short lets and the trap at the end
Listing a rented home on a short-let platform is only lawful where the agreement permits it and the landlord consents; without that it is almost certainly a breach. In London, short-term letting is also subject to the 90-night annual cap under the Deregulation Act 2015, and many leases and mortgages ban it outright.
The worst position to end up in is one people rarely anticipate: you sublet without permission, and the subtenant refuses to leave. You are now their landlord and must follow the proper legal eviction process, while your own landlord takes action against you. Get urgent advice from Citizens Advice or a housing solicitor if that happens — you are carrying obligations in both directions at once.
