Subcontracting vs employing staff: UK tradespeople's guide

Deciding whether to subcontract or employ staff is a significant decision for tradespeople in the UK. With new HMRC guidelines and changing economic conditions in 2026, it's vital to weigh your options carefully. Let's explore the differences, costs, and benefits to help make your choice easier by considering various aspects of both routes in the context of UK trades.

Understanding the basics: subcontracting vs employing

Subcontracting involves hiring independent tradespeople to complete specific tasks or projects. Employing staff means bringing workers onto your payroll with all the associated responsibilities. According to HMRC, subcontractors are not considered employees, which affects tax and compliance obligations. This distinction is crucial as it impacts how you manage your workforce, from payroll to project management.

Cost comparison: what are the financial implications?

Cost is often the deciding factor. As of 2026, employing staff means accounting for National Insurance contributions, which are 13.8% for employers on earnings above £9,100 annually. Subcontractors, on the other hand, handle their own tax through the Construction Industry Scheme (CIS). The financial implications extend beyond just wages, impacting overall business profitability.

Say you're a plumber in Birmingham considering hiring a full-time employee at £30,000 annually. You'd need to budget an additional £4,140 for National Insurance and potentially another £900 for workplace pensions. Compare this to paying a subcontractor £18 per hour, where you'd avoid these extra costs but pay more per hour. This illustrates the importance of aligning your business model with your financial capabilities and project needs.

Flexibility and control: what suits your business?

When employing staff, you have more control over their work and schedules. However, subcontractors offer greater flexibility, allowing you to scale up or down quickly based on project demands. This can be particularly beneficial for seasonal work or unpredictable demand. For instance, if you're a landscape gardener, the spring and summer months might be busier, making subcontracting a viable option to handle increased workloads without long-term commitments.

Consider the scope of work

If your business involves varied projects, subcontracting might be advantageous. For instance, a builder in Manchester handling multiple short-term projects might prefer subcontractors to manage fluctuating workloads without permanent commitments. This approach allows you to leverage specialised skills for specific projects without the overhead of full-time employment.

Legal implications and responsibilities

Employers must comply with employment laws, including providing contracts, managing redundancy, and adhering to health and safety regulations. Subcontractors, however, are responsible for their own compliance, reducing your legal burden. The legal landscape can be complex, and failing to comply with regulations can lead to significant penalties. As an employer, you must ensure all health and safety protocols are followed to protect your workers and your business.

Check GOV.UK for detailed guidance on employing staff. Understanding these obligations will help you make an informed decision on whether to employ staff or subcontract.

Tax and compliance: keeping HMRC happy

Subcontractors must be verified under the CIS scheme. You'll need to deduct 20% CIS tax from their payments unless they’re registered for gross payment status. Meanwhile, employing staff requires PAYE registration and regular submissions to HMRC. The administrative burden of these tasks should be factored into your decision-making process, especially if your business lacks a dedicated accounts team.

Ensuring compliance with HMRC guidelines is non-negotiable. The fines for misclassifying workers or failing to meet tax obligations can be substantial, impacting your business's financial health and reputation.

Real-world examples

Consider Dave, a roofer in Liverpool. By subcontracting during peak summer months, he saved on employment taxes and could offer competitive prices. This approach allowed him to focus on growing his customer base and managing larger projects without the overhead of additional full-time staff. Meanwhile, Sarah, a carpenter in London, found that employing an apprentice gave her consistent help and the opportunity to train staff to her standards. Her decision was influenced by a desire to maintain quality control and develop a loyal team committed to her business ethos. These examples demonstrate how different business models can be tailored to specific objectives and market conditions.

Decision-making strategies

Before making a decision, evaluate your business needs and long-term goals. Are you aiming to expand your services or maintain a steady operation? Consider the nature of your projects. If your work is consistent and predictable, employing staff might be the way to go. However, if your projects vary significantly, subcontracting could be more suitable. It's also wise to consult with a financial advisor or a business consultant who understands the trades industry. They can provide insights into cost management and strategic growth planning. Taking the time to thoroughly assess your current situation and future aspirations will lead to a more informed and strategic decision.
