What the work allowance is and who gets one
The work allowance is the amount you can earn each month before the Universal Credit taper starts reducing your award. It's essentially a protected earnings band, income below the allowance doesn't reduce UC at all.
Not everyone gets a work allowance. It only applies if your household includes a child or a Limited Capability for Work element (the health-related addition). Single adults without children and couples without children who don't have a qualifying health condition get no work allowance, the 55% taper starts from the first pound of earnings.
That distinction matters a lot. Two people earning the same wage can have very different UC outcomes depending purely on whether children or a health condition bring the work allowance into play.
The two rates, £710 and £427, and why they differ
In 2026/27 there are two work allowance rates. If your UC award includes a housing costs element, meaning you get help with rent, the work allowance is £427 a month. If no housing element is in payment, the work allowance is £710 a month.
The logic is that higher housing costs already leave more room in the UC award before earnings push it to zero, so the work allowance for housing claimants is set lower. It's a structural quirk of how the award is built, not a penalty for paying rent.
Practically, this means a single parent in private rented accommodation has a work allowance of £427, while a single parent in a mortgage-free property or living with family (no UC housing element) gets £710.
How earnings above the work allowance are tapered
Once earnings go above the work allowance, UC reduces by 55p for every extra £1 earned. You keep 45p of each additional pound, which sounds modest but is still a meaningful gain.
A worked example: a single parent with two children, no housing element, earns £900 a month. Work allowance is £710. Earnings above the allowance: £227. UC reduction: 55% of £227 = £124.85. So earning £900 instead of nothing reduces UC by £124.85 but puts £900 in wages, a net gain of £775.
At £1,200 a month, the same parent has £527 above the work allowance, so UC drops by £289.85. They've added £1,200 in earnings and lost £289.85 in UC, they're £910 better off overall. The taper slows the gain but never reverses it.
What 'better-off working' really looks like
The common fear is that working will just cancel out in UC. That's not how it works. The taper ensures you always keep something from additional earnings, 45p in every pound above the work allowance. The question is whether that's enough to cover the costs of working (travel, childcare, uniform) and leave a meaningful improvement.
For most households with children, the combination of a work allowance and the 45p-per-pound keep rate means part-time work produces a real financial gain. The point at which UC reaches zero varies by household, but for most families with a work allowance the award doesn't hit zero until monthly earnings are well above £1,000.
