If your partner moves out, you must report the change to DWP immediately. Your joint Universal Credit claim will close, and you will need to make a new single claim. Whether your overall benefits go up or down depends mainly on whether your partner was working. Here is what changes in 2026/27.
Step-by-Step: What to Do When Your Partner Moves Out
- Report the change in your UC journal on the day your partner moves out (or as soon as possible)
- DWP will close the joint claim
- Make a new single UC claim — this can be done immediately
- Update your Council Tax with the local council — apply for the 25% single person discount
- If you have children, confirm to DWP which parent has the children living with them
- Check your Child Benefit and housing situation
How Your UC Amount Changes
| Allowance | Joint claim | Single claim |
|---|---|---|
| Standard allowance | £497.55/month | £316.98/month |
| Income assessed | Both partners’ earnings | Your earnings only |
| Work allowance (with children) | £404/month | £404/month |
| Work allowance (without housing) | £673/month | £673/month |
| Housing element | Based on joint household need | Based on your entitlement |
The couple’s standard allowance is £180.57/month more than the single allowance — a significant reduction. However, you are now assessed as a single person, which means:
- Only your income is counted
- Your work allowance applies to your earnings only
- If your ex-partner had high earnings, your UC could increase substantially
Worked Example: Sophie’s UC Before and After
Before (joint claim):
- Sophie earns £800/month net, partner earns £1,600/month net
- 2 children, renting privately — housing element £700/month
- UC standard allowance (couple): £497.55
- Child elements: £346.05 × 2 = £692.10 (approx)
- Maximum UC: £1,889.65
- Household earnings above work allowance: £800 + £1,600 − £404 = £1,996
- UC reduction (55%): £1,097.80
- UC paid: ~£791.85/month
After (single claim, partner gone):
- Sophie earns £800/month net
- Same 2 children, same rent
- UC standard allowance (single): £316.98
- Child elements: £692.10 (approx)
- Maximum UC: £1,709.08
- Earnings above work allowance: £800 − £404 = £396
- UC reduction (55%): £217.80
- UC paid: ~£1,491.28/month
Sophie’s UC nearly doubles because her partner’s income (£1,600/month) is no longer counted. This is a common outcome when the higher-earning partner moves out.
Housing Element: What Changes
Your housing element is recalculated based on your new circumstances:
- Bedroom entitlement may change — if the property is now too large for a single person or lone parent, LHA calculations may reflect the reduced household size
- LHA rate may change if you need to move to a different area or property size
- If you remain in a shared tenancy, your housing element reflects your share of the rent
Child Benefit After a Separation
Child Benefit continues for whoever the child lives with. Key points:
- Only one person can claim per child
- If responsibility is shared, DWP and HMRC look at where the child primarily lives (usually where they sleep most nights)
- HICBC check: If the High Income Child Benefit Charge applied because your partner earned over £60,000, this may now no longer apply if the higher earner has moved out. Consider reinstating a paused Child Benefit claim if applicable.
Council Tax
Once you are the sole adult in the property, apply for the 25% single person Council Tax discount with your local council. This applies from the date you became the only adult occupant — you can backdate the claim.
