Working as a locum GP provides medical professionals with a dynamic and flexible career path. In the UK, there are over 17,000 locum GPs who fill in temporarily for permanent GPs in practices across the country. This career model is particularly appealing to those seeking greater autonomy, a varied work environment, or a better work-life balance. Locum work offers GPs the chance to sample different practices and regions before committing to a long-term position. Additionally, many salaried GPs take on occasional locum work to supplement their income.<\/span><\/p>\n

Embracing Self-Employment<\/b><\/p>\n

Choosing to become a locum GP is more than a career decision; it is also a step into self-employment. Most locum GPs operate as self-employed professionals, managing their own workload, income, and business responsibilities. While some may choose to form a private limited company, the majority function as sole traders.<\/span><\/p>\n

Being self-employed means you are not employed by the NHS, a GP practice, or a recruitment agency. Instead, you work for yourself, negotiating your own contracts, setting your own fees, and maintaining your own financial records. This setup offers independence and control but also comes with legal and financial responsibilities.<\/span><\/p>\n

Setting Up as a Self-Employed Locum GP<\/b><\/p>\n

To begin working as a locum GP, you must inform HM Revenue & Customs that you are self-employed. This is done by registering for Self Assessment, which is the system used by HMRC to collect Income Tax and National Insurance from self-employed individuals.<\/span><\/p>\n

The registration must be completed by 5 October following the end of the tax year in which you started working as a locum GP. The UK tax year runs from 6 April to 5 April the following year. If you started locum work in May 2024, for example, you must register by 5 October 2025. Missing this deadline can lead to penalties.<\/span><\/p>\n

Managing Your Income<\/b><\/p>\n

As a self-employed locum GP, you will typically be paid directly by the GP practice or service provider you work for. You must issue invoices for the work you complete, detailing the dates and hours worked, the agreed rate, and any additional charges. Payments are made directly to your bank account.<\/span><\/p>\n

You are responsible for keeping track of all income received. This includes maintaining records of invoices, receipts, bank statements, and any correspondence related to payments. Whether you use spreadsheets or accounting software, your records must be accurate and up to date to meet HMRC requirements.<\/span><\/p>\n

Navigating the Self Assessment Tax Return<\/b><\/p>\n

Every year, you must file a Self Assessment tax return using the SA100 form. This form reports your income, allowable expenses, and any tax reliefs you are claiming. HMRC will use the information you provide to calculate your tax bill.<\/span><\/p>\n

The tax return must be submitted by 31 January following the end of the tax year. For instance, for the 2024\u201325 tax year (ending 5 April 2025), the deadline for online submission is 31 January 2026. Paper tax returns must be filed earlier, by 31 October 2025.<\/span><\/p>\n

The tax you pay will depend on your total income and allowable deductions. As a self-employed individual, you may need to make payments on account\u2014advance payments towards your next year\u2019s tax bill. These are due in two installments: one by 31 January and the second by 31 July.<\/span><\/p>\n

Paying National Insurance Contributions<\/b><\/p>\n

Self-employed locum GPs must also pay National Insurance contributions. These are usually Class 2 and Class 4 contributions.<\/span><\/p>\n

Class 2 contributions are a flat weekly rate, while Class 4 contributions are calculated as a percentage of your profits. Both types of NICs are calculated and collected through the Self Assessment system.<\/span><\/p>\n

Keeping Accurate Financial Records<\/b><\/p>\n

Maintaining accurate and detailed financial records is essential. You must keep evidence of all income, expenses, and any tax-related documents for at least six years. This includes invoices, bank statements, mileage logs, and receipts for business expenses.<\/span><\/p>\n

Effective record-keeping not only ensures compliance with tax regulations but also helps you monitor your business performance and profitability.<\/span><\/p>\n

Budgeting for Tax Liabilities<\/b><\/p>\n

Unlike salaried employees, self-employed locum GPs must budget for their own tax payments. Since taxes are not deducted at source, it is wise to set aside a portion of your earnings each month to cover your tax bill.<\/span><\/p>\n

Many professionals recommend reserving 25 to 30 percent of your gross income to cover Income Tax and National Insurance. Setting up a separate savings account for tax liabilities can help ensure you are prepared when payment deadlines arrive.<\/span><\/p>\n

Professional Support and Resources<\/b><\/p>\n

While some locum GPs manage their finances independently, many choose to work with an accountant who specialises in medical professionals. An experienced accountant can help you optimize your tax return, ensure compliance with HMRC rules, and provide guidance on pensions and other financial planning matters.<\/span><\/p>\n

Using digital tools or dedicated accounting software can also streamline your financial management. These tools often include features such as invoice generation, expense tracking, and automated tax calculations.<\/span><\/p>\n

Organising Your Schedule and Contracts<\/b><\/p>\n

As a self-employed professional, you are responsible for managing your own diary, arranging work sessions, and negotiating terms. Locum GPs must coordinate with practices to schedule their work and confirm the details of each session, including the rate of pay, hours, and responsibilities.<\/span><\/p>\n

Clear and consistent communication with the practices you work with is key to avoiding misunderstandings. It is also important to confirm whether travel costs or any other expenses are reimbursed by the practice.<\/span><\/p>\n

Understanding Insurance Requirements<\/b><\/p>\n

All practising GPs are required to have professional indemnity insurance. As a locum GP, you must arrange this coverage yourself. It protects you against claims of clinical negligence and covers legal fees and compensation.<\/span><\/p>\n

You may also consider additional types of insurance, such as income protection insurance, which provides a safety net in case you are unable to work due to illness or injury.<\/span><\/p>\n

Managing Professional Memberships and Development<\/b><\/p>\n

Maintaining your registration and professional knowledge is a crucial part of your role. Membership fees to professional organisations such as the General Medical Council, the British Medical Association, and Royal Colleges are typically considered essential.<\/span><\/p>\n

You are also responsible for managing your own continuing professional development. This includes attending CPD courses, training sessions, and medical conferences. These costs are necessary to keep your skills up to date and remain compliant with professional standards.<\/span><\/p>\n

Gaining Experience and Exploring Opportunities<\/b><\/p>\n

Locum work gives you the chance to explore different types of practices, patient populations, and working environments. Whether you are a newly qualified GP or an experienced practitioner seeking a change, locum work can offer valuable experience and insight.<\/span><\/p>\n

Some locum GPs use this flexibility to find a practice they enjoy before committing to a permanent role. Others choose locum work as a long-term career path that fits their lifestyle and goals. The variety and freedom can be a powerful draw, especially for those who value independence and diversity in their work.<\/span><\/p>\n

Developing a Long-Term Career Strategy<\/b><\/p>\n

While the day-to-day work of a locum GP may be varied and flexible, it is still important to think about your long-term career goals. Whether you are working full-time as a locum or combining it with part-time salaried work, consider your financial future and professional development.<\/span><\/p>\n

This includes planning for retirement, considering investment options, and ensuring that you continue to meet your personal and professional objectives. Working with a financial advisor or career mentor can help you stay on track and make informed decisions.<\/span><\/p>\n

Staying informed and proactive in managing your locum GP career can provide both professional fulfilment and financial stability. In the next section, we will explore how to claim allowable expenses and reduce your tax liability effectively.<\/span><\/p>\n

Importance of Financial Planning<\/b><\/p>\n

Being self-employed brings freedom and flexibility, but it also requires a disciplined approach to managing your finances. Unlike salaried employment, there are no automatic pension contributions, sick pay, or tax deductions. Every self-employed locum GP must actively manage their income, expenses, savings, and investments to maintain financial stability.<\/span><\/p>\n

A good financial plan allows you to track your income streams, manage your costs, and plan for the future. This includes saving for taxes, building an emergency fund, contributing to a pension, and setting aside funds for holidays, illness, or quiet work periods.<\/span><\/p>\n

Building a Reliable Invoicing Process<\/b><\/p>\n

Locum GPs are typically paid directly by the practices or services they work with. To get paid efficiently, you must develop a consistent invoicing routine. Each invoice should include essential details such as:<\/span><\/p>\n
