A day in the life of a night replenishment colleague

This is a composite, built from real night-shift adverts from Sainsbury's, Aldi and Lidl, Tesco's published pay rates, and official guidance from GOV.UK and the Health and Safety Executive (HSE). The colleague below is not a real person, and the hours are one typical example. Real shifts vary by shop and by retailer.

Night replenishment colleagues fill the shelves while the shop is shut or quiet, so it looks full and tidy when the doors open. It is steady, physical work with a small team and very few customers. Here is what a typical night looks like, hour by hour, plus what the job pays and what the law says about night work.

What does a night replenishment colleague do?

You unload the delivery, move the stock onto the shop floor and fill the shelves, so the store is ready for the morning. You also keep aisles clear and clean, rotate stock by date, and flatten and clear the cardboard.

A Sainsbury's night advert we read in September 2026 sets out the main tasks in plain terms:

• Filling shelves at a good, steady pace through the night.
• Moving stock safely from the warehouse to the shop floor, including heavy equipment and containers.
• Working in chilled and frozen areas as well as the main aisles.
• Using equipment, handsets and digital systems to get the work done.

Once you are trained, the same advert says you may also pick online orders or serve on a checkout.

Job titles vary. You might see "customer assistant – nights", "colleague nights", "stock assistant" or "night replenishment". If you search for night jobs, try all of these words.

10pm: How does a night shift start?

The shift in our example runs from 10pm to 6am. The Sainsbury's advert we checked offered 20 hours a week over three nights, with shifts falling between 9pm and 7am. Other shops start and finish at different times, so check the advert.

Clocking in and the briefing

Our colleague arrives about ten minutes early, stores her bag in a locker and clocks in. The night manager runs a short briefing. It covers which aisles each person will fill, how big the delivery is, and anything to watch out for, such as a wet floor or a broken cage.

Walking the shop

Before the delivery is ready, she walks her aisles. She notes the gaps, pulls stock forward so the shelves look full, and checks that nothing is out of date. This is called facing up.

If the shop is still open, she may see a few late customers. A friendly "can I help you find something?" still matters.

11pm: How does the delivery reach the shelves?

The lorry has already been unloaded into the back of the shop, and the stock waits in tall metal cages on wheels. The team wheels the cages out to the right aisles and gets to work.

Moving heavy cages safely

Full cages are heavy and hard to steer. Our colleague takes it slowly and asks for help on a slope or a tight corner.

The HSE says employers must avoid risky lifting where they can, assess the risk where they cannot, and reduce it as far as is reasonable. There is no single legal weight limit, so good training matters. If you are not shown how to move a cage safely, ask.

Working to a steady pace

The goal is simple: the shop should be full and tidy by the morning. Our colleague works in a rhythm: open the case, fill from the back, face up, flatten the cardboard, move on. In your first weeks, being careful matters more than being fast.

Midnight to 3am: What is the middle of the night like?

This is the longest stretch of the shift. The shop is quiet and the work is repetitive. For our colleague, it is the part of the night when tiredness creeps in.

Chilled and frozen aisles

Around midnight, our colleague moves to the chillers. She tries to get chilled and frozen food onto the shelves without leaving it standing around. She wraps up in warm layers, and uses a jacket and gloves if the shop gives them out. Stock is rotated so the shortest date goes to the front, and anything out of date is taken off the shelf.

The break

At about 2am she takes her break in the staff room. By law, if you work more than 6 hours in a day, you get at least one 20-minute rest break without interruption. Whether that break is paid depends on your contract. Some retailers pay breaks: Aldi's careers pages say its paid breaks are worth about £1,500 a year.

She eats a light meal she brought from home, not a heavy takeaway. The HSE advises night workers to eat light, regular meals, such as pasta, rice, vegetables and fruit, and to steer clear of fatty, heavy and sugary food. Light meals are less likely to dull your alertness.

Why the night premium hours matter

On the Sainsbury's advert we checked, every hour worked between midnight and 5am earns an extra £2.45. So these quiet hours are also the best-paid part of the night. Premiums differ between retailers, and some adverts do not split them out at all.

3am to 6am: How does the shift end?

The last few hours are about finishing, clearing up and handing over. By now the cages are mostly empty and the team moves to the aisles that are behind.

The last push

Our colleague helps a teammate finish a big drinks delivery. Then she goes back over her own aisles and faces up again. The cardboard goes to the baler, and the empty cages go back to the warehouse. Floors are cleared so nothing is left for a customer to trip over.

Handover to the day team

Just before 6am, the early staff arrive. The night manager tells the day manager what was filled, what was short on the delivery, and anything that went wrong. Our colleague clocks out at 6am.

Getting home safely

The HSE warns that driving to and from work can be risky, especially after a long shift. It suggests using public transport or a taxi where you can. If you drive, take a little exercise first, do not rush, and stop for a short nap if you feel sleepy. Our colleague lives close by, so she walks home and heads straight to a dark bedroom.

How much do night replenishment jobs pay?

Night workers must get at least the minimum wage for their age. The law does not require a night premium, but most of the supermarkets we checked say they pay one. Here is what we found when we checked in September 2026.

Pay changes often, so always check the figure on the advert before you apply. When you compare jobs, look at which hours the premium covers. A premium that only covers midnight to 5am adds less to a 10pm to 6am shift than one that covers the whole night.

The legal minimum rates from 1 April 2026 are £12.71 an hour if you are 21 or over, £10.85 if you are 18 to 20, and £8.00 if you are under 18. Apprentices get £8.00 if they are under 19, or 19 or over and in the first year of the apprenticeship. When HMRC checks you got the minimum wage, it usually leaves out the extra premium part of your pay. So, in most cases, your basic rate must meet the minimum on its own.

What are your rights as a night worker?

If you regularly work at least 3 hours during the night period, the law treats you as a night worker. That brings some extra protection. The night period is 11pm to 6am, unless you and your employer agree a different 7-hour period in writing that includes midnight to 5am.

• An 8-hour average. Night workers should not work more than 8 hours in each 24 hours, on average. The average is usually worked out over 17 weeks. You cannot opt out of this limit. Regular overtime counts, but occasional overtime does not.
• A free health check. Your employer must offer you a free health assessment before you start nights, and then regularly after that. You can say no, and it may just be a questionnaire. If a health professional says nights are harming your health, your employer must offer you other suitable work where possible.
• Rest between shifts. You are entitled to 11 hours' rest between working days, and 24 hours off each week or 48 hours each fortnight.
• Age limits. Workers aged 16 or 17 cannot work between midnight and 4am. The Sainsbury's night advert we checked asked for applicants aged 18 or over.

If something does not look right, ACAS gives free advice through its helpline. Its night workers page sets out the rules in more detail.

Is night replenishment right for you?

It suits people who like steady, practical work and would rather fill shelves than serve a busy queue. It is harder if you struggle to sleep in the day or have caring duties in the morning.

Looking after your sleep

The HSE says night workers are more at risk of tiredness because day sleep is often lighter, shorter and more easily broken. It also says accidents are more common on night shifts, after a long run of shifts, on long shifts, and when breaks are poor. Its tips include:

• Make your room dark and cool. Blackout blinds or an eye mask help, and so do earplugs.
• Nap before your first night. A short sleep before a new run of nights can help you stay alert.
• Cut caffeine before bed. Avoid coffee, energy drinks and other stimulants for a few hours before you sleep, and use caffeine only now and then.
• Tell people your hours. Let family, friends and neighbours know when you sleep, so they can keep the noise down.

Choosing a pattern that works

HSE good practice suggests keeping runs of night shifts to two or three in a row where possible. It also suggests allowing two nights of full sleep when you switch between days and nights. It is worth asking about the rota at interview.

Night work is a common way into retail, and many retailers train you from scratch. Our guide to retail jobs with no experience explains how to write an application if you have never worked in a shop.

Frequently asked questions

Do I need experience for a night replenishment job?

Usually not. Aldi says training for stock assistants normally lasts around six weeks, and the Sainsbury's advert mentions extra tasks once you are trained. Retailers look for people who are reliable, careful and can keep a steady pace. If you have done any physical or team work before, mention it.

How old do you have to be to work nights in a supermarket?

The Sainsbury's night advert we checked asked for applicants aged 18 or over. The law also stops 16 and 17-year-olds working between midnight and 4am. Check the advert, because the rule can vary by role and shop.

Do night workers get paid more?

Often, but not always. The law does not require a night premium. When we checked in September 2026, Sainsbury's advertised an extra £2.45 an hour between midnight and 5am, and Lidl listed a £3.50 an hour night premium. Aldi said it pays a premium without giving the amount.

How many hours are night shifts?

It depends on the shop. The Sainsbury's advert we checked offered 20 hours a week over three nights, with shifts between 9pm and 7am. Other shops run different patterns. The law says your average should not go over 8 hours in each 24 hours.

Can I work nights and study in the day?

Many people do, but plan your sleep carefully. Tell your manager about your study times, and ask for a rota that leaves you time to rest.
