Key takeaways
- Blending one aesthetics day a week with the NHS job is the highest-survival entry model, not the compromise option
- Declare secondary employment in writing, keep it off rostered hours, never use trust facilities or your NHS role to recruit patients
- Doctors in training declare aesthetics on Form R; omitting it is a probity issue far bigger than the conversation it triggers
- NHS indemnity never covers aesthetics work anywhere, so separate cover is needed from the first patient
- A weekly rented-room clinic day at modest fill produces roughly £22,000 to £25,000 a year of contribution once established, with tax to set aside from the first invoice
The most asked and least answered question in aesthetics is not clinical. It is logistical. Can you build an injecting practice on your day off without blowing up your NHS career, your revalidation or your relationship with a training programme director who thinks you should be “living, breathing and sleeping” your specialty? Thousands of practitioners have done exactly this. Almost nobody writes down how, so here is the operating manual.
The blended model is the normal one
Course marketing sells the great escape. The data says otherwise: the typical successful entry is one aesthetics day a week alongside the substantive job for one to three years, because the first-year diary is slow and the NHS salary is what funds the patience. Blending is not the compromise option. It is the strategy with the highest survival rate, and it keeps your pension, sick pay and skills current while the patient list compounds.
Your contract comes first
Before booking a course, read your contract and your trust’s policies on secondary employment. Almost every NHS contract requires you to declare outside work rather than seek permission for it, but the wording varies, and consultant job plans and junior doctor contracts have specific provisions. Three rules keep you safe. Declare it in writing through the proper channel. Never let it touch your rostered hours, including arriving exhausted after late-night clinics. Never use trust facilities, consumables or your NHS role to recruit patients. The practitioners who get into difficulty almost always broke one of those three, not some obscure regulation.
Doctors in training
Two specifics come up on every forum thread. Form R first: if you are in a training programme, declare aesthetics work on your Form R as other professional activity, exactly as you would locum work. Leaving it off a revalidation declaration is a probity issue, which is a far bigger problem than any conversation the declaration itself triggers. Second, the culture question (“I don’t want to be quietly labelled not committed”). You do not need your TPD’s blessing to work on your day off, but you do need to be honest if asked, compliant with hours limits, and sensible about not advertising your sideline across the mess. Portfolio careers are increasingly normal, and a declared, well-run one reads very differently from a discovered one.
Study leave and funding
Study leave budgets exist for your training programme’s curriculum, and aesthetics is not on it. Asking to use study leave for a botox course is the kind of request that costs goodwill even when it succeeds, so take annual leave for courses and treat the fees as business investment (they are usually deductible against your aesthetics income once trading, our tax guide covers the basics). The exception is genuinely dual-purpose training such as a prescribing qualification, where a case sometimes exists.
Revalidation and appraisal
This is the question that decides whether the model works for years or unravels. Your licence is one licence. Everything you do under it goes through one appraisal and one revalidation.
For doctors, whole-practice appraisal means your aesthetics work must appear in your appraisal portfolio: scope, volumes, CPD, complications, compliments and complaints, the same as your NHS work. If you leave the NHS entirely you still need a designated body or suitable person and an annual appraisal, which independent practitioners typically arrange through private appraisal providers or membership organisations. Plan that route before you resign, not after.
For nurses, NMC revalidation needs 450 practice hours over three years (which aesthetics hours count towards), 35 hours of CPD, reflective accounts and a confirmer. A part-time aesthetics practice alongside NHS work meets this comfortably. A solo full-time aesthetics practice meets it too, but you need to be deliberate about your confirmer and your CPD evidence, because nobody organises it for you.
Either way, the isolation problem is real: no clinical supervision arrives by default in aesthetics. Build it in deliberately (our alumni join monthly case-review calls for exactly this reason, and our after-the-certificate guide covers the first-90-days structure).
Indemnity is not one policy
Your NHS work is covered by the clinical negligence scheme. Your aesthetics work is not, in any circumstances, even if you are treating a colleague in the hospital car park as a favour, which is one of several reasons never to do that. You need separate aesthetics indemnity from day one of treating anyone, and your medical defence organisation should be told your practice profile has changed. The insurance guide explains what invalidates cover; moonlighting-related misdescription is on the list.
The one-day-a-week arithmetic
Worked example with stated assumptions, adjust freely. A Saturday clinic in a rented room (£60 day rate), four appointments at the earnings report’s contribution figures, is roughly £450 to £500 of contribution. Fifty Saturdays would be £22,000 to £25,000 a year before tax, on top of your salary. The honest catch: months one to six will not fill four slots, Saturdays cost you weekends for as long as you run them, and self-assessment tax on the extra income needs setting aside from the first invoice (roughly 30 to 40% once you count national insurance, depending on your band). It works. It is work.
Sequencing that works
- Check contract and declare secondary employment in writing ☐
- Train on annual leave (foundation course, two clinical days) ☐
- Arrange indemnity and a prescriber before your first patient ☐
- Open one clinic day a fortnight, upgrade to weekly when it fills ☐
- Add aesthetics to your appraisal/revalidation evidence from month one ☐
- Review at month twelve with real numbers, then decide about hours ☐
Where Aurelia fits
Most of our delegates train exactly this way, which is why courses run as two intensive clinical days rather than scattered half-days, why dates include weekends, and why the eligibility review is free and will tell you plainly if your plan does not add up. Bring your contract questions to it. We have seen most versions of this conversation.

Frequently asked questions
Almost all NHS contracts require declaration of outside work rather than permission, but wording varies. Declare in writing through your trust’s secondary employment process, keep the work off rostered hours, and never let it touch trust facilities or patients.
Study leave exists for your programme’s curriculum, and aesthetics is not on it. Take annual leave for courses. A prescribing qualification is the one case where a dual-purpose argument sometimes exists.
No, in no circumstances, even treating a colleague as a favour. Aesthetics needs its own indemnity policy from the first patient, and your defence organisation should know your practice profile has changed.
Doctors still need an annual whole-practice appraisal and a designated body or suitable person, usually via private appraisal providers. Nurses meet NMC revalidation (450 practice hours, 35 CPD hours, a confirmer) but must organise evidence deliberately. Plan before resigning.
