Night Shift Workers – UK Laws & Regulations For Night Workers

There are laws and regulations that apply to employees who work night shift. These apply to all employees whether they permanent members of staff or casual workers on zero hour contracts.

Night shift work is regulated to protect workers.

Laws on Night Shift Hours in the UK

UK night working hours are between 11pm (23.00) and 6am (06.00) although this agreement can be slightly varied between employers and workers if all parties agree. A ‘night worker’ is classed as someone who works for at least 3 hours during this period.

Night Shift Hours

Generally, night shift workers:-

  • Should not work more than 8 hours in any 24 hour period, averaged over 17 weeks.
  • Cannot opt-out of from this limit unless it is allowed for by a collective workforce agreement, although in some cases you can average night work over a 26 week period.
  • Must be offered a free health assessment before they begin night work duties and on a regular basis after that.

For some workers – those Working with Hazards or under mental or physical strain – there can be no averaging at all – the 8 hour limit must be strictly adhered to.

Rest Periods For Night Shift Workers

There are rules on rest periods between shifts for all workers. In general there should be:-

  • Minimum 11 hours rest between finishing work and starting the next night shift.
  • 24 hours rest in a 7 day period.
  • 48 hours rest in a 14 day period. This is usually taken as one block but can be 2 x 24 hour periods.

Exceptions To Rest Period Rules

There can be some exceptions to rest period rules for night workers. For example, a switch from night shift to day shift might mean that it’s not possible to provide an 11 hour rest period. Similarly, a variation in shift times might mean there is not enough time to give a rest period.

Employers should do their best to provide rest periods to workers. It is important to note that workers on zero hour contracts have the same rights as other workers to rest periods.

Minimum Age For Working Night Shift

In general, workers under 18 are not permitted to work nights, although there are exceptions to this rule. You can find out more from the Department of Business, Innovation and Skills (BIS).

Employers Duties & Night Worker Regulations

It is an employer’s duty to comply with the night work regulations. They should keep records to ensure workers do not exceed their night working limit. Records of their employees’ health assessments should be kept for 2 years or, if they didn’t take up that offer, the date the offer was made should be recorded.

How to Adapt to Working at Night

A human’s body clock was designed to be awake during daylight hours and to sleep at night. Many night workers have experienced difficulty in adapting to the changes in working at night and sleeping during the day.

Some good tips include:-

  • Timing meals and other activities to match the new ‘day’.
  • Exercise can often sort out body rhythms. Try starting your new ‘day’ with a brisk jog or by cycling. This may mean doing exercise at 10 o’clock at night, but it has proven to have been beneficial for many night shift workers.
  • Although not always possible, studies have shown that a short nap in the middle of a night shift can help maintain or improve performance later on in the shift. You could try this during your longest rest break during your shift.
  • One of the most common complaints with night shift work is difficulty in sleeping during the day. It’s important to try and create the same relaxing environment as you would normally do if you were sleeping at night. Your room should be well ventilated and not too hot. It should be as quiet as it would be at night so if you have a family, they should consider your needs sympathetically. If need be, you should install black-out window blinds so that your bedroom is as dark as possible and consider ear plugs and sleeping masks for your eyes, such as those you might get offered on a plane.
  • When eating on the night shift, choose smaller portions rather than a heavier meal. This can make you feel tired and sluggish and can sometimes cause heartburn. Also try to avoid late night caffeine as this can have an adverse effect when you get home in the morning and are trying to get to sleep.

    Hi I have have my working shifts changed recently so now my working hours are 23.00-07.30. I was told at the start of working these shifts that I would have every Monday and Tuesday night off but after a couple of weeks of working these hours they have now started splitting my days off up, for example this week I am off Monday night and Friday night. Are there any working laws that state I should be having a certain amount of working hours off together now because having my days off split is a real struggle with regards to my sleeping

    looking at the 8 hrs working limit for night time shifts. If night time is 23.00 to 7.00 then you can’t work more than 8 hrs in 24 hr period. I work at a dock .very hard manual work and work 12hr shifts from 7pm to 7 am so I presume its how they get around the law

    Useful info, thank you. Some of these comments are shocking! Know your rights, and speak to HR or the Citizens Advice Bureau. Your health and well-being come first, don’t let anyone bully you.

  16. jules says:

    I am expected to do sleep in nights at a children’s home sleeping either in the dining room or the office, where I will be the only adult female sleeping caring for 4 children in the home. The home is employing a waking nights gentleman who doesn’t speak much English, who will be able to access all areas while I am asleep. This is making me feel very uncomfortable.

  17. Riley says:

    10 8 hour night shifts in a row, hotel. 11 till 7. My 4 days off over the 2 weeks were put at the opposite ends of the weeks. Do I have any right to complain? Seems like a long stretch.

  18. Irvin says:

    I work from 9pm to 5:30am. I have a mandatory meeting the next day at 1pm and that only gives me like 7 hours of sleep. Do I still have to show up to the meeting that will probably last like an hour and a half.

    I work a pattern of 5 x 12 hour night shifts (18:30-06:30) and regularly have to do an extra hour (at least once a week. I’m also a lone worker driving around a site. My job title is driver. I’ve asked if this is legal and have been told to suck it up and do as I’m told because “the law states an 8 hour break from the workplace”. I’ve also been refused health checks as I’m agency. I’ve been here nearly 18 months.

  23. Lizzie says:

    My manager wants me to stay at work on the morning I finish after doing 3 12 hr night shifts in a row to do mandatory training. I’ve explained I’m too tired and need to go home to rest. Is this allowed. I’ve offered to go in an hr early or for the manager to come in at 7am to train me but she says she won’t. Now I’m up on a discipline meeting because of this which I think is totally unfair.

  26. To says:

    Hi! I’m new to the UK work laws and I would like to know if it’s legal to work 12 hours a day 7 days a week with changing day/night pattern (7 nights 3 days off/7 days 4 days off)if your company doesn’t have any other option for your position? Because website tells that you can’t work more than 48 hours weekly only in some special cases. And I don’t get the rules about changing patterns when you have day shifts following night shift so you are becoming a night worker and the other laws applies to you and your work time?

    Thank you.

  27. Yvonne Bradbury says:

    If night shift overtime becomes available should it be offered to other night shift workers first before day shift take it

  28. Fred Lawton says:


    Great article by the way.

    I worked a 4 on, 4 off. However when I applied for an internal role I was told that the interviews have to be carried out during my “free-time”. The last interview that I had was carried 5 hours after my last night shift. Am I allowed to come in within the “set time” since its within the 11 hours period. Along with that, in the case that “Interviews are a working meeting” should one be claiming overtime” since its outside thier set working time?
