Mutual exchange 

A mutual exchange is when a council tenant or a housing association 'swap' properties with the prior consent of their landlord. Two or possibly multiple tenants will exchange their homes anywhere in the country, you are not restricted to properties in Hillingdon. Probationary tenants are not permitted to do a mutual exchange during the lifetime of their probation.
