Setting up my own business as a GP: what I wish I’d known

2nd February 2026 by Dr Clare Sieber, sessional GP workforce advocate, NASGP

Setting up my own business as a GP: what I wish I’d known

A couple of years ago an opportunity landed in my lap that I felt compelled to take up; starting a business with a colleague, the nature of which was completely outside of my clinical work, specifically a company offering software and professional services focused on compliance.

Looking back now, having bought out my co-founder and then taken the company through an acquisition and divested myself of it, I have lots of reflections and useful learning should I take on a similar challenge in the future.

Clinicians have many transferable skills that work well in entrepreneurial positions (the ‘Doctorpreneur’!) including our ability to manage uncertainty and risk, and make decisions nevertheless. However, like every other human inhabiting the Earth, we can’t be great at everything, and that leads nicely on to my first recommendation:

Surround yourself with experts of a different type

We have a tendency to work and socialise with people who are similar to ourselves both in terms of thinking but also in ways of working. Whilst it is ideal to work with someone with similar values, it is also ideal to work with people who do things very differently and are naturally skilled and knowledgeable in areas that we are lacking; the business needs all-round expertise with keen eyes on all of the business functions. It is that old mantra of only being as good as your weakest link.

Do not underestimate the time and financial investment required

I’d recommend some careful thought very early on about whether the financial investment required for your organisation to grow is going to be injected personally (or with loans personally guaranteed) or sought from investment. There are pros and cons to both options. I personally opted for control but this did come with considerable financial pressure, that was pretty much a daily feature in my life, and frankly one I was glad to see the back of.

Consideration also needs to be given to the time involved and how this is going to be managed. How much will be outsourced versus how much will be done by yourself? Again, there is no right nor wrong answer here, but factoring in how much of your free time you are willing to forgo and having a sense of what value – monetary and otherwise – you want to place on your time, will help these decisions to emerge. If I had to guess as to the level amount of time I committed to the business I co-founded, I would estimate that it was at least three days a week and that was sustained right through until acquisition.

Have a plan, derived from a purpose

This sounds simple, but a start-up will need a plan, and that plan will very regularly need to be reviewed in light of progress or otherwise and unforeseen circumstances. A plan with clear, measurable goals, or KPIs will be looked upon favourably by investors, buyers and team members. The plan will be influenced by the purpose of the company to you as the founder, and that is sometimes not always well thought through at the beginning. Is this a company you are looking to sell in five years and retire from the proceeds of? Or is this going to be a company that gives you lifelong income and stability? Both will result in very different plans immediately from the outset.

Data is your friend

In order to demonstrate that you are achieving your plan, you will need to have some data. I would recommend measuring everything you possibly can, looking for patterns and trends after every new decision is implemented, and changing your direction based on what the data tells you. Data will drive solid decisions; opinion may not. It will also drive changes, sometimes U-turns, because it will also be telling you what isn’t working…

Don’t be afraid of mistakes

Success isn’t easy, and no one gets it right first time. When something goes well, it is because it has not gone so well the time before and a decision was made to do something differently based on the learning from that. It can feel like a personal failure to have made a ‘wrong’ decision and sometimes there is a tendency to keep going with the same plan hoping that next time might be different to ‘save face’, but in my opinion the failure lies in ignoring the evidence and pressing on without any learning.

Prepare for intense scrutiny

Having gone through the ‘due diligence’ of an acquisition, I can share that every single decision that you make as founder will be questioned. The best answers will be backed up with data. For example ‘We set these prices based on these calculations’ or ‘This is our main method of marketing and it is based on some early market testing that we did, the results of which are here’ goes down very well. Justification of your moves is the level of understanding that an investor requires.

In order to have robust data, all business decisions need to be well documented, and as much data as possible should be monitored. Decent software makes this easy and therefore more likely to be done, so I would highly recommend having a solid ‘tech stack’ that makes data collection and interpretation as easy as possible; gone are the days of mail merges for email marketing with zero visibility after send, and spreadsheets for sales pipelines.

Network, network, network

Many answers are out there, from the thousands of other people who are or have been in similar positions to yourself, who are usually more than happy to impart some knowledge. Good old social media, particularly LinkedIn is a great place to start (I have made lifelong friends on it and met many peers and colleagues whose insights I have been grateful for), but as are the face to face events. This requires a degree of extroversion of course, but that’s something that can be worked upon and will be improved with practice (I am a Myers-Briggs introvert myself!).

In summary, there is a lot to consider before taking the plunge into founding a business, and there is no guaranteed recipe for success, but I believe the above ingredients at least give a recipe for an outcome to be proud of, one that can be stood behind with a sense of achievement. That is ultimately what my experience was – it did not make me a millionaire, but it enriched my life and career and brought a whole heap of learning that will no doubt come in handy in the future.

I would love to connect with past, present and future Doctorpreneurs (and not just in the tech sector!) and share our learning for the benefit of all – do reach out!

Frequently-asked questions about portfolio GP work

Which training costs can GP locums claim for?

The rules for salaried GPs and self-employed GP locums are different.

Get the latest advice on expenses and tax relief from this 2023 article by Liz Densley and Tori Ferguson of Honey Barrett. 

Salaried GPs

If you are a salaried GP you can only claim for courses that are ‘wholly, exclusively and necessarily’ in the course of your work. The ‘necessarily’ is the tricky bit – because that would mean absolutely anyone doing that job would have to do that course. The effect of this is that generally salaried doctors cannot claim training costs, so ideally get them built into the remuneration package so that the practice pay for them. Providing it is work related, it will not be a taxable benefit.

There was talk of training being treated differently just before the 2018 Budget, but nothing came of it. Be aware that the rules may change in the future.

GP locums

If you are a self-employed doctor, you can claim for courses that are ‘wholly and exclusively’ for the purposes of your work. This gives much more scope.

Generally any courses that are keeping you up to date or improving your existing skills will be deductible. Anything unrelated to your work won’t of course – so a GP couldn’t claim for a course on plumbing or bricklaying!

A new qualification – or something that enables you to do something that you cannot currently do – will be treated as ‘capital’ and will not be deductible. There is a grey line between what is a new skill and what is an extension of an existing skill – and that needs professional advice when it arises.

What does ‘wholly and exclusively’ mean? Generally there won’t be personal benefit in a course, but beware ‘holiday’ courses where HMRC could argue that the holiday element is more than an incidental part of the cost. Once there is ‘duality of purpose’ (such as a holiday with some training), HMRC are within their rights to refuse the whole of the claim.

What is the cost of the course? That will be the course cost itself, any related reading material etc, travel to get there, subsistence and reasonable accommodation (if it is not reasonable to return home).

What if you are both salaried and self-employed?

It will normally be acceptable to claim course costs against the self-employed income. If HMRC want to be awkward, they could argue duality of purpose – because you can’t learn something and only use it for your self-employed work. We had this point made in an investigation some years ago, but HMRC did back down and agree the cost in full against the self-employed work (but on a reasonable basis, rather than under the letter of the law). If you are trying to claim for a £5k course against £5k of locum work when you are employed full time, expect it to be questioned!

How should private work be charged?

Salaried GP

This will be stated in the written contract. The private fee can either be entirely subsumed within the normal, regular work of the salaried GP, or there could be a provision for private work to be undertaken over and above the their usual work, stating how much of the fee they receive (bearing in mind the practice’s overheads.

Locum GPs

For locum GPs, there is no issue as to whether or not a freelance GP can perform private work in a GP practice.

The practice and locum will need to agree beforehand whether their normal clinical caseload will contain private as well as NHS patients, with adequate time given for the private work in line with what other GPs in the practice would expect.

The practice and locum will also need to agree between them whether private work is charged at the same rate as NHS work.

Model locum Terms and Conditions template

If you’re doing any sort of locum work as part of your portfolio career, you’ll definitely need your own personalised Terms and Conditions to help protect both you and the practice you’re working for.

NASGP’s model T&Cs has been specifically developed for NASGP members by a specialist employment law firm. It allows GP locums to not only fully adopt all its recommendations, but also to add any necessary clauses and tailor it to suit each locum’s personal needs.

You can now set your T&Cs online in NASGP’s LocumDeck.

LocumDeck’s T&Cs generator allows you to set:

  • Your own cancellation sliding scale from 0 to 100% of your booked fee for 0 to 28 days in advance.
  • Your 14.38% employer’s pension contributions
  • Legal employment status
  • Tax status, IR35 etc
  • Duties (on-call, triage etc)
  • Private fees (HGV medical etc)
  • Cremation fees
  • Payment terms (14 days? 28 days?)
  • Plus much more.

As an NASGP member, go to your T&Cs generator, choose your settings and then save. You’ll then be given a unique link, “View my TCs” which will automatically be added to your automated invoices, confirmation emails and session request emails, or you can paste the link into your own GP locum website.

As an added bonus, GP locums can update their T&Cs as often as they like on LocumDeck. Each change is saved in an archive, accessible by practices, for extra confidence.

In our experience, if private patients are seen within the usual agreed hours then the locum would not expect to be paid any extra. But if seen outside the usual agreed hours, the locum would expect to be paid the full private fee, with any practice overheads being offset by the additional service being offered by the locum. It makes the paperwork easier too.

How many GP locums work in the UK?

How many GP locums work in the UK? No one seems to know how many GP locums there are in the UK. All data pertaining to the number of GPs in the UK states “excluding locums”.

As we wrote in a recent news story, salaried GP numbers in England now surpass GP locum numbers. In 2015, the salaried GP workforce was just 70% of the size of the GP locum workforce; in 2024, it was 104%.

Using the GMC’s methodology of estimating the number of GP locums (by subtracting the number of salaried GPs and partners from the GMC’s register of practising GPs), the number of GP locums fell from 21,091 in 2023 to 17,836 in 2024 – an estimated fall of 3,255 in a single year.

These new figures have emerged at a time when GPs face a double workforce crisis: GP partners struggle to fund the GP vacancies they need, and sessional GPs struggle to find both salaried and locum roles.

Read our 2017 report.

At the time, 28% of all GPs worked outside a managed organisation.

This raised many questions, including:

  1. How does the profession represent these GPs?
  2. Will this have an effect on the resources allocated for revalidation?
  3. Assuming the Department of Health does not know about these GPs, then how can it make plans for future manpower resources and training?
  4. If 28% of all GPs practise outwith traditional salaried posts or partnerships, what is the profession and Department of Health doing to engage these 17,000 GPs into the clinical governance systems of the
    NHS?

The Government and profession needs to ensure that its resources are allocated equitably, and reassurance given to patients that the quality and professional welfare of its GP locums is not being ignored.
