How Long Does a Mutual Exchange Take?
A UK social housing mutual exchange typically takes 6 to 12 weeks from the point both tenants submit their applications, although finding a suitable swap in the first place can take considerably longer. The legal decision window itself is capped at 42 days.
The guide below sets out each stage of the process for council and housing association tenants in England, Scotland, Wales and Northern Ireland.
Stage-by-Stage Timeline
| Stage | Typical duration | What happens |
|---|---|---|
| 1. Finding a potential swap | Varies — days to many months | Your details remain on the matching database until a tenant whose property and area suit you (and vice versa) is identified. There is no fixed timescale: it depends on stock in your chosen areas. |
| 2. Initial viewing and agreement | 1–2 weeks | Both households arrange to view each other's home and agree in principle that the swap is suitable. |
| 3. Submitting the application | Same day to 1 week | Each tenant submits a mutual exchange application form to their own landlord (council or housing association). Both applications must be lodged before the clock starts. |
| 4. Landlord checks and inspection | 2–4 weeks | Landlords check rent arrears, tenancy conduct, property condition and gas/electric safety. A home inspection is normally carried out during this period. |
| 5. Statutory decision window | Up to 42 days | Under section 92 of the Housing Act 1985 (and equivalent housing association rules), the landlord has 42 days from receipt of a valid application to give a written decision. Refusal is only allowed on specific statutory grounds. |
| 6. Deed of assignment and move | 1–2 weeks after approval | Once both landlords have approved, the tenants sign a deed of assignment and exchange keys on the agreed date. |
What Can Slow an Exchange Down
- Outstanding rent arrears on either tenancy.
- Required gas, electric or asbestos safety checks taking longer than expected.
- Repairs the landlord asks the tenant to complete before approval.
- Active legal action — for example a notice seeking possession.
- The property being significantly under- or over-occupied for the incoming household.
Common Grounds for Refusal
Landlords cannot refuse a mutual exchange arbitrarily. The most common statutory grounds for refusal include:
- A court order for possession is in force.
- The property would be substantially overcrowded.
- The accommodation is materially larger than the incoming household reasonably requires.
- The property is designed for a person with particular needs (for example wheelchair-adapted) and the incoming tenant would not require those adaptations.
