Do you have to declare a second job to the NHS?

In practice, yes. Most NHS employment contracts and local policies require staff to tell their line manager about any other paid work, and to get agreement before starting it. The declaration is usually a short written note or a form held on your personal file: what the job is, who the employer is, and roughly how many hours a week it takes. It is not a request for permission to earn extra money in general. It is a check that the second job does not clash with your NHS role.

The reason trusts ask is patient safety and probity, not curiosity. A nurse who also works for a private provider that treats NHS patients, a manager who also works for a supplier to the trust, or a porter who also drives for a patient-transport firm that bids for trust work all sit in a grey area where private interest and public duty overlap. Declaring the job lets your manager spot that overlap early and agree boundaries, such as not working on procurement decisions that touch your second employer. If you do not declare it and the overlap comes out later, the problem is no longer the second job itself. It is the failure to declare it, and that is what disciplinary cases tend to turn on.

Check your own contract and your trust's secondary-employment or conflicts-of-interest policy before you start, because the exact route varies. Some trusts ask for a manager's written agreement, some ask only for notification, and some route declarations through a declarations-of-interest register. The safest approach is the same in every trust: put it in writing, keep a copy, and do not start the second job until you have a reply. If your manager says no, ask for the reason in writing too, so you can challenge it or adjust the plan, for example by dropping the conflicting hours rather than the whole job.

What counts as a second job?

Anything you are paid for outside your substantive NHS post counts, even if it feels like NHS work. The common forms are:

• Bank shifts at your own trust or another trust. These are the most common second job in the NHS, and the easiest to declare, because the employer is the NHS itself. Bank work still counts as a second employment for tax purposes, even when it is at your own hospital.
• Agency shifts. Agency work is a separate employment with a separate payroll, even when the shifts are on NHS wards. See agency vs bank pay for how the two compare on rates, tax codes and pension.
• Private healthcare work. Shifts or clinics for a private hospital, care home, GP practice or dental practice. This is where conflicts of interest bite hardest, especially if the provider treats NHS-funded patients.
• Self-employed work. Locum shifts taken as a sole trader, private tutoring, consultancy, or a small business on the side. Self-employment brings its own tax return duties on top of PAYE from your NHS post.
• Non-healthcare work. Retail, driving, hospitality or any other job outside health. These rarely create conflicts, but hours and fatigue still matter, and they still need declaring under most contracts.

Unpaid volunteering does not usually need a secondary-employment declaration, but the same fatigue and conflict questions apply in common sense terms. If a voluntary role leaves you unfit for a night shift, it is a problem whether or not it is paid. Some trusts also ask senior staff and procurement staff to declare unpaid directorships and family interests, so read the conflicts policy, not just the secondary-employment paragraph.

Can your trust refuse a second job?

A trust can refuse, but in practice outright refusals are uncommon and usually tied to a specific risk. The grounds managers rely on are consistent across trusts: a direct conflict of interest, a clash with your contracted NHS hours, a pattern of sickness or fatigue linked to total working hours, or a second job that uses NHS time, equipment or patient contacts for private gain. A refusal should come with a reason you can work around. If the problem is a clash with one clinic day, changing the second job's hours may fix it. If the problem is a conflict with a supplier, dropping that one client may fix it.

What a trust cannot reasonably do is refuse because it dislikes the idea of staff earning extra money, or because a manager wants first call on your spare time beyond your contract. Your contracted hours are the trust's; your remaining time is yours, subject to the declaration, conflict and fitness checks above. If you believe a refusal is unreasonable, the route is your union representative and the trust's grievance process, with your written declaration and the written refusal as the evidence. Keep both.

Senior staff should expect closer scrutiny. Managers, consultants and anyone involved in purchasing, recruitment or waiting-list decisions will usually have their declarations checked against the trust's register of interests, and may be asked to step out of decisions that touch their second employer. That is normal governance, not suspicion, and it protects you as much as the trust.

Working time, rest and fatigue

The hardest limit on a second job is not your contract. It is your body. Working-time law sets a 48-hour weekly average limit for most workers, with an opt-out that many NHS staff groups use, as explained on our Working Time Directive pay page. The opt-out is about the legal average, not about what is safe. A full-time NHS post plus a second job can easily push total hours past the point where concentration, driving safety and clinical judgement suffer, even where no single employer sees the full picture.

Each employer only sees its own rota. You are the only person who sees the combined total, so the responsibility for keeping it safe sits with you. Count every job's hours together when you judge whether you are fit for a shift, including travel time between jobs. Watch for the warning signs that managers and colleagues notice first: repeated lateness, sickness absence that clusters after second-job shifts, and mistakes on routine tasks. If your NHS performance or attendance slips and the cause is total hours, the trust will treat that as a performance matter, not as an excuse.

Rest matters as much as total hours. Night shifts followed by a second job the next morning, or a weekend of agency shifts before a Monday of NHS clinics, leave no recovery time. Build at least one genuinely free day into each week where you can, and be honest with both employers about availability. Turning down a second-job shift because you are not rested is not unreliability. It is the judgement both employers are paying for.

Second jobs and tax: BR, D0 and your allowance

Tax causes more second-job surprises than any other issue, because the system works differently from what most people expect. Your personal allowance of £12,570 for 2026/27 is normally given in full by your main job, through the standard 1257L code. That leaves no allowance for the second job, so HMRC usually puts the second job on a BR code: every pound taxed at 20%, with no allowance. This is correct, not an error, and it is the single most common reason staff think their second job is being overtaxed. Full detail is on our tax code explained page.

The table below shows what BR tax looks like at common levels of second-job income. The chart plots the tax column.

Worked example one: a Band 5 nurse on the entry salary of £32,073 takes bank shifts worth £10,000 a year. Total income is £42,073, still below the £50,270 higher-rate threshold, so the second job stays on BR and the tax on it is £2,000. The nurse keeps £8,000 of the £10,000 before any pension or student-loan deductions that apply to that employment.

Worked example two: a Band 7 manager on the top salary of £56,515 already earns above the £50,270 threshold in the main job alone. A second job worth £5,000 is therefore likely to be coded D0, which taxes every pound at 40%, so £2,000 is deducted during the year. Where total income genuinely sits above the threshold, that 40% is the right rate, not an overpayment. Where coding goes wrong in either direction, HMRC reconciles it after the tax year through a P800 calculation, and you can speed up a correction by updating your estimated income from each job in your Personal Tax Account.

Two traps are worth naming. First, if both jobs somehow end up on 1257L, you get the allowance twice and underpay tax all year, which lands as a bill later. Check the first payslip from any new job, not the tenth. Second, National Insurance is worked out separately for each employment, so the tax-code logic above does not carry across to National Insurance. If a second-job payslip looks odd, compare the tax code first, then ask that employer's payroll, because each payroll can only see its own slice of your income.

Bank and agency work as a second job

Bank shifts are the cleanest form of second job for NHS staff. The employer is a trust, the rates follow the band for the shift, and unsocial-hours enhancements apply in the usual way for hours worked at unsocial times. Bank pay is still a second employment for tax: it normally carries a BR code, as above, and it is paid through a separate payroll record even at your own trust. Keep bank income in your own yearly total, because neither payroll will do that addition for you.

Agency shifts as a second job need a closer look at the declaration. The agency is a separate employer, and agency work for a competing provider or on wards where you hold NHS responsibilities can create the conflicts described above. Agency payrolls are also the most likely to default a new starter to an emergency code, so check the first agency payslip against the code HMRC has issued. If you already work agency shifts alongside a substantive post, our agency vs bank pay guide sets out the rate, pension and tax differences in full.

Part-time staff and second jobs

Part-time staff often have the clearest case for a second job, because their NHS post leaves contracted days free. The rules are the same: declare it, watch conflicts, watch total hours. One pay detail is worth knowing. Overtime in your substantive post is judged against that post's contracted hours: hours above your contracted hours up to 37.5 a week are paid at plain time, with overtime rates only above 37.5, as set out on our part-time pay page. Hours worked for a second employer do not count towards your NHS post's overtime threshold, and NHS hours do not count towards the second job's. Each employment keeps its own clock.

Part-time staff should also check how a second job affects benefits tied to hours. Annual leave is worked out per employment: your NHS leave follows the Agenda for Change tiers of 27 days plus 8 bank holidays with under five years of service, rising to 29 plus 8 at five years and 33 plus 8 at ten years, pro rata for part-time hours. A second job has its own leave entitlement from its own employer, and the two do not combine into a single pot. The same separation applies to sick pay: each employment has its own sick-pay terms, and being fit for one job does not automatically mean you are fit for the other.

Pension, leave and the sick-leave trap

A second NHS post usually means a second pension record, and contribution tiers are worked out on each post's pay rather than on your combined income. Do not assume your two posts together push you into a higher tier, and do not assume they do not. Ask the relevant payroll how your tier has been set if the deduction on a second-job payslip looks unexpected. The same ask-payroll rule applies to any second job outside the NHS with its own pension scheme: auto-enrolment duties sit with each employer separately.

The sick-leave trap deserves a paragraph of its own, because it ends careers. Working a second job while signed off sick from your NHS post, or claiming NHS sick pay while working elsewhere, can be treated as a disciplinary matter and, in the worst cases, as fraud. There are legitimate exceptions, such as a phased return or a second job that involves completely different duties your doctor has cleared, but those exceptions need to be agreed in advance and in writing with your manager and occupational health. Never assume silence is agreement. If you are off sick, tell your manager about any second-job work before you do it, not after.

Finally, remember that a second job does not change your NHS notice, redundancy or pension rights, which stay tied to your substantive post and its terms. If a second job ever threatens your substantive post, for example through a conflict that cannot be managed, the substantive post is the one to protect. Second jobs come and go. Your NHS service record, pensionable service and band progression do not rebuild easily.

Frequently asked questions

Do I have to tell the NHS about a second job?

In practice, yes. Most NHS contracts and local policies require you to declare other paid work to your line manager, usually in writing, before you start it. The declaration lets the trust check for conflicts of interest and for hours or fatigue risks. Failing to declare a second job is more likely to cause disciplinary trouble than the job itself.

Can the NHS stop me having a second job?

It can refuse a specific second job where there is a real risk, such as a conflict of interest, a clash with your NHS hours, or a fatigue problem that affects patient safety. Outright refusals are uncommon, and a good refusal comes with a reason you can work around, such as changing the second job's hours or dropping one conflicting client. If you think a refusal is unreasonable, raise it through your union representative and the grievance process.

Are bank shifts a second job?

Yes, for tax and declaration purposes, even bank shifts at your own trust count as a second employment with a separate payroll record. Bank shifts are usually the easiest second job to declare, because the employer is the NHS itself, but they are still normally taxed under a BR code, because your personal allowance is already used by your main job.

Why is my second job taxed at 20% from the first pound?

Because your £12,570 personal allowance for 2026/27 is normally given in full by your main job through the 1257L code. That leaves no allowance for the second job, so HMRC puts it on BR, which taxes every pound at 20%. This is correct, not an error. If your total income passes £50,270, HMRC may instead use D0, which taxes every pound of the second job at 40%.

Can I work a second job while on NHS sick leave?

Do not do this without written agreement in advance. Working a second job while signed off sick from your NHS post, or claiming NHS sick pay while working elsewhere, can be treated as a disciplinary matter and in the worst cases as fraud. Legitimate exceptions, such as different duties cleared by your doctor, need to be agreed beforehand with your manager and occupational health.

Does a second job affect my NHS pension?

A second NHS post usually means a second pension record, with contribution tiers worked out on each post's pay rather than on your combined income. Do not assume your two posts together push you into a higher tier. If a deduction on a second-job payslip looks unexpected, ask that payroll how your tier has been set.

Can I work agency shifts as a second job?

Yes, but declare it and watch for conflicts, because the agency is a separate employer and may supply providers that compete with or contract to your trust. Agency payrolls are also the most likely to default a new starter to an emergency code, so check the first agency payslip against the code HMRC has issued for that job.

What happens if my second job pushes me over the higher-rate threshold?

Once your total income passes £50,270 a year, the slice above that threshold is taxed at 40%. HMRC may move your second job to a D0 code so the 40% is collected during the year instead of landing as a bill later. For example, a Band 7 manager on the top salary of £56,515 already earns above the threshold in the main job alone, so a £5,000 second job on D0 has £2,000 deducted during the year. Any overpayment or underpayment is reconciled after the tax year through a P800 calculation.
