The short answer
- You choose the visits you takeFamilies search, and you agree the visits and times with each one. How much work there is depends on what families near you need, so nothing guarantees a set number of hours.
- Two incomes, two ways of paying taxYour job is taxed through payroll. Care income over £1,000 in a tax year means registering for Self Assessment, where HMRC adds the two together.
- Your job usually uses your Personal Allowance firstIf your job pays £12,570 or more, Income Tax is due on your care profit from the first pound, so set aside a share of every payment.
- Check your visa before you take a clientGov.uk says Student visa holders cannot be self-employed, and Health and Care Worker visa holders can take extra work only in limited cases.

Choosing your hours
You pick your visits, and the ones you agree are binding
Carers on PrimeCarers are self-employed. Nobody hands you a rota: families search for a carer near them, and you agree with each one which visits you will do and when. That is what lets care work fit around other commitments.
Carer resources has the full set of guides for carers. This one is for somebody with a few hours a week to give, whether that is around a job, a course or children at school.
The visits that fit most easily around other work are the ones with a set time: a morning call before your shift, a teatime visit, a weekend, or a night. Night work covers sleeping and waking nights. A single visit of six hours or more is charged at our lower 15% commission, so a carer advertising £18 an hour for a long weekend shift keeps £15.30 of each hour. Shorter visits are at 20%, so a £20 hour pays you £16. Leave time for travel between a job and a visit, because travel is not paid unless the client agreed it in advance, in writing.
Live-in work is booked by the week rather than by the hour, so it does not fit around a weekly job. Some live-in carers work a week or two at a time, sharing a placement with another carer. What families are told about part-time live-in care explains the patterns they are offered.
What stays flexible, and what the contract fixes
| Yours to decide | Once visits are agreed | |
|---|---|---|
| Hours and clients | Which families you work with, which visits you accept, and what you advertise as your rate. | The contract covers the visits you agreed. Neither of you has to offer or accept more work after that. |
| Ending it | Whether to take on a new client at all. | 48 hours' notice for hourly care. For live-in care, 7 days once you have worked 168 hours, and 48 hours before that. |
| Cancellations | You can waive part or all of a cancelled visit if you choose. | A visit the client cancels is payable in full, except for unplanned hospitalisation, illness, or another reason you both agree. |
| Time off | When you take holidays. | The carer terms ask you to tell the client at least two weeks ahead if you want to arrange cover. |
| Cover | Who you ask to stand in for you. | You can send a suitable substitute. You arrange and pay them, and the client can raise a reasonable objection. |

From the contract between each client and carer, and the PrimeCarers carer terms.
If your job's hours change and you can no longer do the visits you agreed, give the notice above rather than stopping. Without it, the contract lets the client recover reasonable costs of replacement care. The carer terms also ask you to tell PrimeCarers if you can no longer accept work, and allow a profile to be removed where jobs are frequently turned down, so keep what you tell families about your availability accurate. The full contract sets out both sides.
When you know which hours you can offer, you can register as a carer on PrimeCarers and set your own rate, or first see the carer jobs open near you.
Tax on two incomes
How tax works when you are employed and self-employed at once
Gov.uk is clear that you can be employed and run your own business at the same time. The two are taxed in different ways, and what trips people up is the Personal Allowance, the income you can have before you pay Income Tax.
Your job is taxed through PAYE. Your employer uses your tax code, which gov.uk says is 1257L for most people with one job, to give you the standard £12,570 Personal Allowance through payroll and take tax and National Insurance before you are paid. Nothing is taken from your care income before it reaches you.
Your care work is self-employment. Gov.uk says you must register for Self Assessment as a sole trader if you earn more than £1,000 in a tax year, before any expenses. Below that, the trading allowance means you may not need to tell HMRC, though you still keep records. Your return then adds your care profit to your pay and works out the Income Tax on the total, allowing for what payroll has already taken.
The same care work, three ways
How a job changes the tax on your care income
8 hours of visits a week at £20 an hour, with our fee included, for 46 weeks of the year. £16 of each hour reaches you after our 20% commission, so the year comes to £5,888 before your expenses.
Care work is your only income
No other job, so none of your allowance is used elsewhere.

Class 4 National Insurance is worked out on your care profit alone, so it starts only once that profit passes £12,570, whatever your job pays. Income Tax is worked out on everything together.
An illustration, not a forecast of work or earnings. Your allowable expenses come off the profit first and lower both figures. The job's own tax and National Insurance are taken through payroll and are not shown. Rates for 2026/27: gov.uk Income Tax rates, self-employed National Insurance rates and the National Living Wage from April 2026. Checked 22 September 2026.
Class 4 National Insurance is 6% on self-employed profits over £12,570, and it looks only at your care profit. So a carer with a full-time job and a few visits a week usually owes Income Tax on the care work but no Class 4.
If you owe less than £3,000 and already pay tax through PAYE, HMRC can collect the bill through your tax code over the following year, as long as you file online by 30 December. Otherwise you pay it yourself by 31 January. How to pay tax as a self-employed carer walks through registering and filing, and allowable expenses covers what lowers your profit.
Your job and your visa
Check your employment contract and your visa before you start
Two things can stop you taking private clients alongside other work: a clause in your job contract, and the conditions of your visa. Both are worth checking before you agree a first visit.
Your employment contract
Student visa
Health and Care Worker visa
Read the Acas guidance on exclusivity clauses, then the contract itself. If a clause is unclear, ask your employer in writing before you start rather than after.
For visas, the rules are on gov.uk: the Student visa page, and taking a second job on a Health and Care Worker visa. For your own case, speak to an OISC-regulated immigration adviser. Visas and self-employment and right to work checks for carers go further. PrimeCarers checks your right to work when you register, with your identity, an enhanced DBS check issued within the last 18 months, and a recorded online interview.
Universal Credit
Universal Credit when care work sits alongside a job
If you claim Universal Credit, the question is whether caring is your main work. DWP's rules for self-employment, including the minimum income floor, depend on the answer.
How Universal Credit treats care work, by where it sits in your week
| Caring is your main work | Caring alongside a job | |
|---|---|---|
| Gainfully self-employed? | Possibly. DWP checks it is your main job or main source of income, and that it is organised, developed, regular and expected to make a profit. | Unlikely while the job is your main work, because the test needs caring to be the main one. |
| Earnings used | Your own earnings in a start-up period of up to 12 months, then your earnings or the minimum income floor, whichever is higher. | What you earn from the job and from caring, added together. |
| Looking for other work | Not required while you are gainfully self-employed. | You may be asked to, as agreed with your work coach. |
| Each month | Report your self-employed earnings, even if they are nothing. | The same, and your wages count as well. |

Questions
Questions about part-time care work
You choose which families to work with and which visits to accept, so you can offer as few or as many hours as suit you. How many visits there are near you depends on what local families are looking for, so nothing guarantees a set number of hours. The carer jobs open near you show what is being asked for now.
Yes, if your care income is more than £1,000 in the tax year, before expenses. PAYE only covers your job. You register for Self Assessment as a sole trader and declare the care income on a return, where HMRC works out the tax on both together.
It can. If you owe less than £3,000, already pay tax through PAYE and file online by 30 December, HMRC collects the bill through your tax code over the next 12 months, unless you ask it not to on your return.
No. Gov.uk lists being self-employed among the things a Student visa holder cannot do. Check the Student visa page or speak to an OISC-regulated adviser about your own situation.
Payment follows each client's billing, so different clients can pay out on different days. How you get paid explains the stages, and what carers earn on PrimeCarers shows what reaches you after our fee.
