Cost of employing retail staff UK (2025/26)
Retail is the UK's largest private-sector employer, and the majority of retail staff are paid at or close to the National Living Wage. In 2025/26, a full-time retail assistant on NLW (£12.21/hour) earns approximately £23,810 per year. The employer's total cost — salary, employer NI (15% above £5,000) and minimum pension — is approximately £27,155 per year. For retailers employing large numbers of part-time workers, each individual employee has their own NI threshold assessment. The April 2025 threshold change (from £9,100 to £5,000) has added approximately £790 per full-time NLW employee per year in additional employer NI.

Frequently asked questions
How much does a part-time retail worker cost an employer?
A part-time retail worker on 20 hours per week at NLW (£12.21/hr) earns approximately £12,699/year. Employer NI on that salary is approximately £1,155 (15% of £7,699 above the £5,000 threshold) and minimum pension is approximately £195. Total employer cost before overheads: approximately £14,049/year. The NI threshold (£5,000) applies in full, not pro-rated for part-time hours.
Do retailers have to pay pension on minimum wage staff?
Yes, if the employee is aged 22–66 and earns more than £10,000/year. For full-time NLW staff earning £23,810, auto-enrolment is mandatory. For part-time staff earning under £10,000, they can opt in but are not automatically enrolled — however if they opt in, the employer must still contribute at minimum 3% of qualifying earnings.
How does Employment Allowance help retail employers?
For small retailers with total employer NI below £10,500/year, Employment Allowance can eliminate the entire NI bill. A small shop with five full-time NLW staff generates approximately £14,105 in total employer NI per year, so Employment Allowance (£10,500) would reduce net NI payable to approximately £3,605 per year. Larger retail chains above the eligibility criteria cannot claim.
