Subletting Rules for Social Housing Tenants in Wales

Subletting a social housing property in Wales can be complicated, especially if you’re facing changes in your housing needs or plan to be away for an extended period. It’s important to understand your rights and the necessary steps before considering subletting, to avoid risking your tenancy or legal trouble.

What Does Subletting Mean in Social Housing?

Subletting is when a tenant rents out all or part of their home to another person. In the context of social housing in Wales, this usually means renting out a council or housing association property, either fully or partially, to someone else without moving out yourself.

  • Subletting the whole property: You move out and let someone else live there in your place.
  • Subletting part of the property: You remain living there but rent out a room to another person.

Subletting is different from taking in a lodger, which has separate rules. If you’re unsure, contact your local council’s housing department for advice.

Is Subletting Allowed in Welsh Social Housing?

The default position under Welsh housing law is that tenants cannot sublet their social housing property without written permission from their landlord. This rule is set out in the Renting Homes (Wales) Act 2016, Section 91.[1]

  • If you sublet your home without written consent, you could lose your tenancy through eviction.
  • If your landlord refuses permission, you should not sublet—doing so would breach your occupation contract.

Landlords, such as your council or housing association, may have specific policies about subletting. These rules are usually set out in your contract or tenancy agreement.

When Might Subletting Be Allowed?

In some circumstances, social landlords may consider applications to sublet part of your home. For example, if you have a spare room and want to help with housing costs, or if your circumstances change temporarily (e.g., a temporary work placement). Always check your individual tenancy agreement and talk to your landlord for guidance.

How to Request Permission: Forms and Steps

If you’re thinking of subletting, you must always get written permission from your landlord first. This usually involves completing a specific application form provided by your council or housing association. There is no single national standard form; each social landlord may have their own.

  • Step 1: Contact your landlord (council or housing association) to ask for the correct subletting application form. For example, Cardiff Council provides a downloadable application—check your landlord's website.
  • Step 2: Explain why you wish to sublet, who will move in, and for how long.
  • Step 3: Wait for written approval before making any arrangements.

Example: If you live in a Newport City Council property, you can request permission to sublet a room by contacting their housing team and completing their specific application form. They will review your case and respond in writing.

What Happens If Permission Is Refused?

Your landlord can lawfully refuse subletting requests—reasons may include overcrowding concerns, breaches of tenancy, or suitability of the property. If refused, you must not proceed. To challenge a refusal, you may use your landlord’s complaints process or contact the Public Services Ombudsman for Wales.

Risks of Unauthorized Subletting

Subletting your social housing without permission is a clear breach of your occupation contract, giving your landlord grounds to seek repossession (eviction). You could lose your home and may even be required to repay any profits made from unauthorized subletting. Always get permission first and seek advice if unsure.

Relevant Legislation and Tribunal for Wales

Always check your own agreement and council policies—they may be more restrictive than the law requires, but they cannot overrule basic statutory protections.
