Deductions from universal credit
If deductions to third parties are made from UC, they are usually made at a fixed rate of 5 per cent of the client’s standard allowance, with the following exceptions.
•Deductions for child support maintenance are made at a flat rate of £8.40 a week (£36.40 a month) for ongoing liability or £8.40 a week (£36.40 a month) for arrears.
•Deductions for rent arrears are made at a rate of at least 10 per cent but not more than 20 per cent of your standard allowance.
In practice, deductions of any kind from UC do not usually exceed 25 per cent of the client’s standard allowance. If the client has more than one deduction, see here for how this limit applies. Third-party deductions cannot leave the client with less than one pence of UC.1Sch 6 para 3(1)(a) UC,PIP,JSA&ESA(C&P) Regs
