How mutual exchange works: the complete UK guide
Mutual exchange is how most social-housing tenants actually move. Here's exactly how it works, from first listing to moving day.
What a mutual exchange actually is
A mutual exchange is a swap. Instead of waiting years on a transfer list, you find another social tenant who wants to move to where you are — and you move to where they are. Two homes, two (or more) households, one switch.
It's the fastest route to moving for most council and housing-association tenants, because it doesn't depend on a new property becoming available. It depends on finding the right match.
Who can do it
Most secure council tenants and assured housing-association tenants have a legal right to exchange. In practice you'll usually need to be up to date with your rent and not in breach of your tenancy.
You can swap with a tenant of any council or housing association in the UK — you're not limited to your own landlord. The two homes don't have to be the same size or type, although size differences can affect whether a landlord agrees (more on that in our guide on landlord consent).
The process, step by step
From start to finish, a typical exchange looks like this:
- List your home with clear photos and say what you're looking for.
- Find a match — a direct swap, or a multi-way chain where three or more households move at once.
- Message and visit. View each other's homes and check it's right.
- Apply for consent. Both landlords must approve the exchange in writing.
- Sign and move. Once approved, you sign a deed of assignment and set a moving date.
How long it takes
The match is the variable part — it can take days or months depending on how in-demand your area and property type are. Once you've found a match, landlords in England generally have 42 days to give a decision.
So the realistic timeline is: however long the match takes, plus roughly six to eight weeks for checks, consent and paperwork.
What it costs
The exchange itself is normally free — there's no stamp duty and no estate-agent fees, because you're swapping tenancies, not buying. Your costs are the practical ones: removals, redirecting post, and any disconnection or reconnection fees.
Some matching services charge tenants a subscription. HousingBase is free to list and match for your first year.
Where people go wrong
The two most common mistakes are thin listings and waiting for a perfect direct swap. Homes with several clear photos and a specific 'what I want' get far more interest. And if you only ever look for a direct A-to-B swap, you miss the three- and four-way chains that make a move possible when no direct match exists.
