The moment a partner moves into your home, your Universal Credit changes from a single claim to a joint claim — from the very first night. This is one of the most significant changes you can report to DWP. Here is exactly what to expect and what you need to do.
The Change: Single to Joint Claim
When you move from a single to a joint UC claim, everything is recalculated:
| Element | Single claim | Joint claim |
|---|---|---|
| Standard allowance | £316.98/month | £497.55/month |
| Work allowance (with housing, child/LCWRA) | £404/month | £404/month (not doubled) |
| Income assessed | Your earnings only | Both partners’ earnings combined |
| Capital assessed | Your capital only | Both partners’ capital combined |
| Work requirements | Your requirements only | Both partners have requirements (unless exempt) |
The couple allowance is higher, but both incomes are now counted — which often reduces UC more than the allowance rise compensates.
Step-by-Step: What to Do When Your Partner Moves In
- Report immediately — log into your UC account and report the change via your journal or the “Report a change” section. State the date your partner moved in.
- Your partner creates a UC account (if they don’t have one) — they verify their identity and are linked to your claim.
- DWP closes individual claims — your old single claim closes from the date of the change.
- Joint claim opens — DWP creates a new joint claim, usually from the same date. There may be a brief processing gap.
- Joint Claimant Commitment — both you and your partner sign new commitments reflecting your joint circumstances.
How Your Partner’s Income Affects UC
If your partner works, their earnings are counted in the joint UC assessment. The 55% taper applies to combined household net earnings above the work allowance.
Example: You currently receive UC as a single person with one child (no housing costs). You earn £400/month net. Your partner moves in and earns £1,800/month net.
| Before partner moves in | After partner moves in | |
|---|---|---|
| Standard allowance | £316.98 (single) | £497.55 (couple) |
| Child element | £388.00 | £388.00 |
| UC maximum | ~£704.98 | ~£885.55 |
| Work allowance | £673/month (child, no housing) | £673/month |
| Combined net earnings above allowance | £0 (only £400 income) | £1,527 (£400 + £1,800 − £673) |
| UC reduction (55%) | £0 | £839.85 |
| UC paid | ~£704.98 | ~£45.70 |
A significant reduction — but you are still better off as a household overall.
If Your Partner Has No Income
If your partner moves in and has no income (for example, they are studying, job searching, or have just left work), your UC can increase:
- The couple allowance (+£180.57/month vs single) applies
- No additional income reduces UC via the taper
- Your partner’s circumstances (disability, health, children) may add further elements
Your partner will also need to agree a Claimant Commitment — if they are of working age with no limiting condition, they will need to look for work.
Capital: Joint Assessment
Once you are a couple on UC, both partners’ capital is combined. If your partner brings in savings above £6,000, tariff income will apply to the joint claim. If combined capital exceeds £16,000, UC stops entirely.
The Housing Element
Your housing element is based on your actual rent and the Local Housing Allowance rate for your property size. If your partner moving in means your household has more adults, the LHA size criteria may change — for example, you may now qualify for a different bedroom entitlement. Report the change and DWP will reassess.
