Thank you. When you are a worker you are usually entitled to receive the National Minimum Wage. The rate of 18-20 year olds is currently £5.30 per hour. So you are entitled to receive at least that rate for the hours you are working. If you work 14 hour days over 6 days a week then your wages should be in the region of £445 a week.
There are certain exemptions, for example if you are an apprentice or if you are a family worker where you are provided with food and accommodation but for this to apply you must be treated as being part of a family and take part in family activities, such as a nanny. It would not really apply to you.
Saying that, there is a provision for certain pay and benefits to count towards the minimum wage you should get and accommodation is one of them. The only non-cash benefit provided to the worker that should be taken into account is the value of any accommodation provided by the employer. Currently the employer can deduct a maximum of £5.35 a day for accommodation allowance. So even over 6 days a week the maximum they can reduce your pay by would be £32, giving you a minimum wage entitlement of approximately £413 a week based on the hours you work.
So I would say that it is unlikely the employer is acting lawfully here because they are not paying you the National Minimum Wage rates which you are entitled to by law.
This is your basic legal position. I have more detailed advice for you in terms of the options you have of challenging this further, which I wish to discuss so please take a second to leave a positive rating for the service so far (by selecting 3, 4 or 5 stars) and I can continue with that and answer any further questions you may have. Don’t worry, there is no extra cost and leaving a rating will not close the question and we can continue this discussion. Thank you
