Is Contracting the Way Forward for UK Contractors?

The working world has changed significantly in the UK over the last few years. Fluctuating economies, new tax regulations and different workplace expectations have left many contractors questioning: is contracting still right for me? For some, there is still no beating the flexibility and earning potential. For others, the growing compliance burden and risks of IR35 have made the permanent route more appealing.

If you’re considering your options, this article from Compare Your Pay experts will help you. Let's explore the reality of contracting in today’s UK market—the benefits, the drawbacks, and the future outlook.

The Case for Contracting

1. Higher Earning Potential

One of the biggest draws of contracting has always been the opportunity to earn more than in permanent employment. Skilled contractors in IT, engineering, finance, healthcare, and construction can often command daily rates far higher than their salaried counterparts.

Even when you factor in tax, insurance, and downtime between contracts, the financial upside can be significant—especially for those with in-demand skills.

2. Flexibility and Control

Contractors enjoy the freedom to choose when, where, and how they work. You’re not tied to a single employer, and you can decide which projects to take on. This independence makes it easier to balance work with personal life, travel, or family commitments.

In an era where flexible working is more valued than ever, contracting puts you in charge.

3. Variety and Career Development

Moving from project to project gives contractors exposure to different industries, teams, and technologies. This variety can be stimulating and hugely beneficial for your CV. You’ll continually learn and grow—often faster than in a single permanent role where progression may be slow.

4. Potential Tax Efficiency

If you operate through a limited company and fall outside IR35, you can benefit from tax efficiency by paying yourself through a mix of salary and dividends. This often means a higher take-home pay compared with PAYE employees.

The Challenges of Contracting

While the rewards are real, contracting isn’t without its drawbacks.

1. IR35 and Compliance Burden

The IR35 legislation remains the single biggest issue for contractors. If your contract falls inside IR35, you’ll be taxed much like an employee but without receiving employment benefits such as holiday pay or pensions.

Since the off-payroll reforms were extended to the private sector in 2021, many clients have become risk-averse, placing more roles inside IR35 by default. This has squeezed contractors’ take-home pay and made tax planning more complex.

2. Income Security

Unlike permanent employment, contracting doesn’t guarantee a steady pay cheque. Contracts may end suddenly, and there can be downtime between roles. Without proper financial planning, this uncertainty can be stressful.

3. No Employee Benefits

Contractors do not get sick pay, holiday pay, company pension or training budget. You have to do these yourself, so you have to be strategic and look ahead.

4. Admin Tasks

Limited company owners have to do bookkeeping, tax returns, and general compliance. Most use an accountant, but there is still some onus and admin that permanent staff don’t have to deal with.

Contracting vs Permanent Employment

For some, the question isn’t “should I contract?” but rather “should I stay contracting or move back to a permanent role?”

Permanent Employment provides:

• Stability and consistent income

• Benefits (holiday, pension, sick, training)

• Career advancement within the one organisation

• Less admin and compliance stress

Contracting provides:

• Higher potential income

• Flexibility and independence

• Variety of projects and industries

• Control of your own career

The “right” option depends on your personal circumstances, appetite for risk, and long-term goals.

Is Contracting Still Worth It in the IR35 Era?

IR35 changes have certainly impacted the contracting market. Some individuals have been pushed inside IR35, effectively losing the earning potential of contracting. Some others have become ‘employee-umbrellas’, sacrificing tax efficiency for ease and protection from HMRC.

That said, contracting is far from dead. In fact, demand for flexible, skilled professionals continues to grow. Businesses still need contractors to fill specialist gaps, deliver projects, and provide short-term expertise.

If you position yourself correctly and choose contracts wisely, contracting can still be highly rewarding.

Tips for Making Contracting Work in 2025 and Beyond

If you’re considering whether contracting is the right path for you, here are some practical steps to follow:

Know IR35 – Understand the rules and how they apply to your contracts. Seek expert advice if necessary. 

Build a Financial Buffer – Aim to save 3–6 months of expenses to cover periods of downtime.

Invest in Skills – Stay relevant by learning new technologies, management techniques, or sector-specific knowledge.

Use a Specialist Accountant – An accountant experienced in contractor issues can save you time, stress, and money.

Consider an Umbrella Company – If most of your contracts are inside IR35, an umbrella company may simplify your finances.

Network Strategically – Many contracts come through recommendations and personal contacts. Build and nurture your network.

Think Long-Term – Plan for retirement, health cover, and professional development. Don’t just focus on day rates.

The Future of Contracting in the UK

Despite challenges, the contracting market shows no signs of disappearing. Businesses increasingly rely on a flexible workforce to manage costs and remain competitive. The rise of remote working has also broadened opportunities, allowing UK contractors to take on projects both nationally and internationally.

However, government policy will continue to shape the market. With Labour now in power, contractors will be watching closely for any changes to IR35 or wider tax reforms. While these could bring further uncertainty, history shows that contractors are adaptable—and opportunities remain for those who stay informed and prepared.

Final Thoughts

So, is contracting the way forward for UK professionals? The answer depends on your priorities.

• If you value flexibility, independence, and higher earning potential, contracting remains a strong path.

• If you prioritise stability, security, and employee benefits, a permanent role may suit you better.

For many, the best solution is a blended approach—contracting during high-demand years to maximise income and experience, then moving into permanent employment later for stability.

Contracting isn’t for everyone. But for those with the right mindset, skills, and financial discipline, it still offers one of the most dynamic and rewarding ways to work in the UK today.

A clear glossary acts as a quick reference guide, cutting through the complexity. Instead of spending hours trying to decipher HMRC documents or legal wording, you can look up a plain-English definition and understand straight away what it means for your career. This helps you avoid costly mistakes, gives you confidence in negotiations, and ensures you stay compliant with the latest legislation.
