Introduction

Hiring flexible staff such as freelancers, contractors, or temporary workers offers UK SMEs the agility they need to thrive. However, the legal landscape governing these arrangements is increasingly complex. From IR35 reforms coming into effect in April 2025, which raise the thresholds defining “small companies” and shift IR35 responsibility back to contractors, to mandatory Right to Work checks with fines up to £60,000 for non-compliance, and GDPR obligations for handling personal data securely, SMEs must navigate a minefield of regulations to avoid costly penalties and reputational damage.

The Growing Compliance Challenge

Navigating employment compliance is becoming increasingly complex for UK SMEs, particularly when engaging flexible staff such as freelancers, contractors, or temporary workers. One of the most significant regulatory changes on the horizon is the update to IR35 rules, which govern off-payroll working and aim to prevent disguised employment.

From 6 April 2025, the thresholds defining a “small company” will increase significantly. To qualify as a small company, a business must meet at least two of the following criteria:

  • Annual turnover not more than £15 million (up from £10.2 million)
  • Balance sheet total not more than £7.5 million (up from £5.1 million)
  • No more than 50 employees (unchanged)

This change means many businesses previously classed as medium-sized will now be considered small. For IR35 purposes, this shifts the responsibility for determining a contractor’s employment status back to the contractor’s own intermediary, rather than the client SME. While this reduces the compliance burden for SMEs, it also means they must remain aware of their obligations and the risks involved.

Alongside IR35, Right to Work (RTW) checks remain a legal requirement for all workers, including temporary and freelance staff. Employers must verify and retain valid documentation before employment begins, with fines of up to £60,000 for each illegal worker found.

Data protection under GDPR also adds complexity, requiring SMEs to handle contractor personal data securely and lawfully, with appropriate policies and safeguards in place.

Together, these regulations create a growing compliance challenge for SMEs seeking to hire flexible staff safely and legally.

Common Pitfalls for SMEs

Many SMEs struggle with compliance due to a lack of awareness or misunderstandings about their legal duties. Common pitfalls include:

  • Incorrect or incomplete Right to Work checks, particularly for agency or zero-hours workers, which can lead to costly penalties.
  • Misclassifying workers as self-employed when they should be treated as employees, resulting in unexpected tax and National Insurance liabilities.
  • Failing to maintain proper documentation increases legal exposure during audits or investigations.
  • The ongoing administrative burden of keeping up with evolving employment laws and regulations, which can overwhelm small HR teams or business owners.

Avoiding these pitfalls requires clear processes, up-to-date knowledge, and often, trusted support from compliance experts.

IR35 Explained Simply for SMEs

IR35 is a set of tax rules designed to prevent “disguised employment,” where individuals supply services through intermediaries (such as personal service companies) but effectively work as employees. The rules ensure that such workers pay broadly the same taxes as regular employees.

The 2025 changes to company size thresholds mean that many SMEs will no longer be responsible for determining IR35 status; instead, this responsibility shifts back to the contractor’s intermediary. Medium and large businesses, however, must continue to assess and operate IR35 rules.

Despite this shift, SMEs should still understand IR35 and take practical steps to remain compliant, including:

  • Clarifying the nature of engagements with contractors
  • Ensuring contracts accurately reflect working arrangements
  • Keeping records of status determinations and related communications
  • Seeking expert advice when unsure about classification

Understanding IR35 helps SMEs avoid unexpected liabilities and maintain good working relationships with flexible staff.

Right to Work Checks: A Non-Negotiable

For UK SMEs, conducting Right to Work (RTW) checks is a legal requirement that cannot be overlooked. Employers must obtain, verify, and securely retain valid documentation confirming that every worker, whether permanent, temporary, contractor, or freelancer, has the legal right to work in the UK before employment begins.

Acceptable documents fall into two categories: those establishing a permanent right to work (such as a British or Irish passport) and those granting a time-limited right (such as a visa or biometric residence permit). From 1 January 2025, significant changes come into effect, including the introduction of digital right-to-work checks via the Home Office online checking service for individuals with eVisas. Employers must be prepared to use these digital tools alongside manual checks where applicable.

Best practice involves:

  • Meeting the individual in person or via a live video call to verify documents
  • Checking the authenticity of documents, including photographs, expiry dates, and consistency of personal details
  • Making clear, unalterable copies of documents and securely retaining them for the duration of employment plus two years
  • Staying updated on evolving Home Office guidance to ensure ongoing compliance

Failure to conduct proper RTW checks can lead to civil penalties of up to £60,000 per illegal worker, criminal charges, and serious reputational damage.
