Over the past decade, the UK contracting sector has undergone a seismic shift. Legislative reforms—particularly around IR35, the Construction Industry Scheme (CIS), and umbrella companies—have reshaped the way contractors work, earn, and engage with clients.

If you’re a contractor trying to make sense of it all, you’re not alone. With more professionals searching “What’s the best way to contract in 2025?”, “Can I still work through a limited company after IR35?”, or “Is CIS compliance being cracked down on?”, it’s clear that the landscape is evolving fast—and not always in the contractor’s favour.

IR35 & the Off-Payroll Working Rules: A Sector Still in Recovery

The 2017 and 2021 IR35 reforms shifted the burden of determining employment status from the contractor to the end client in both the public and private sectors. While the government framed these changes as a way to close tax loopholes, the reality has been much more disruptive.

• Limited company contracting (PSC model) has dropped significantly, with many clients applying blanket bans to avoid risk.
• “Can I still work outside IR35 in 2025?” is now one of the most common questions among contractors.
• Freelancers have left the sector altogether, citing reduced autonomy and rising compliance risks.
• HMRC continues to pursue more IR35 investigations, pushing hard for adoption of its widely criticised CEST tool.

For contractors operating through a limited company, questions like “How to prove I’m outside IR35?” or “Can I get IR35 insurance?” are now daily concerns—especially with increased scrutiny from tax authorities.

Construction Firms on Alert

In parallel, construction contractors working under the CIS (Construction Industry Scheme) are seeing more HMRC enforcement.

Key areas of focus include:

• Deemed contractor rules and the £3 million threshold
• Subcontractor verification issues
• Increasing use of real-time data to track inconsistencies

These changes are sparking searches such as:

💬 “How do I stay CIS compliant in 2025?”
💬 “What are the new HMRC CIS rules?”

Whether you’re a sole trader or director of a construction firm, staying compliant with CIS rules is no longer optional—it’s essential for avoiding penalties.priority, especially as HMRC increases its use of real-time data tools to flag inconsistencies and fraud.

The Rise (and Risks) of Umbrella Companies

As limited company options shrink, many contractors have found themselves pushed into umbrella company arrangements.

Nearly 30% of contractors now work via umbrellas, but this model has introduced new concerns:

• Contractors are often treated like employees but without true benefits or protection
• Many ask: “Is working through an umbrella company worth it?”
• Some umbrellas operate non-compliantly, engaging in tax avoidance or applying unauthorised deductions

The government is now preparing reforms that may shift PAYE liability from umbrellas to recruitment agencies, raising questions such as:

💬 “What will replace umbrella companies?”
💬 “Can I go back to a limited company model?”

Expect major changes in this area—and stay alert.

Mounting HMRC Pressure: More Investigations, More Penalties

Across all contracting models—umbrella, limited company, or CIS—HMRC is increasing enforcement. Their tactics now include:

• Digital investigation tools
• Retrospective tax claims
• Steep penalties, even when rules are ambiguous

Contractors are increasingly searching:

💬 “How do I protect myself from an HMRC audit?”
💬 “Do I need IR35 insurance in 2025?”

The answer is yes: staying compliant is critical, but so is having protection in place in case you’re wrongly targeted.

Recommendations: How Contractors Can Protect Themselves

In the face of uncertainty, here’s what all contractors should be doing now:

• Regularly review your IR35 status with professional support
• Maintain accurate records of contracts, expenses, and correspondence
• Invest in IR35 insurance to protect against legal costs during investigations
• Consider business protection insurance to cover income loss from illness or other interruptions
• Stay informed about reforms affecting umbrella models, PAYE responsibilities, and CIS rules

Many contractors now ask:

💬 “What insurance should I have as a contractor?”
💬 “Can I protect my day rate if I get sick?”

These aren’t just smart questions—they’re survival strategies in the current climate.

A Sector at a Crossroads

The UK contracting model is under pressure like never before. Between IR35 enforcement, CIS scrutiny, and potential umbrella reform, freelancers and independent professionals are being squeezed.

For those still navigating the system, it’s clear: the future of contracting in the UK is being rewritten.

While change is inevitable, it must be balanced. Policymakers should support—not punish—the highly skilled, flexible talent that fuels key sectors across the UK. That starts with fairer regulation, more clarity, and systems that work for everyone—not just the tax office.

If you’re a contractor, recruiter, or small business owner navigating this shifting landscape, make sure you’re informed, protected, and supported by expert advice.
