What is Interim Management?

Interim management is when senior professionals are brought in on a temporary basis. They lead projects, manage change, or help steady organisations during difficult periods. They can work at different levels of seniority and often bring many years of experience, allowing them to make an impact quickly.

Common interim roles include:

• Finance Director
• Head of Strategy
• Head of Transformation
• Programme Director
• Regulatory or Compliance Lead

Interim managers take responsibility for delivery. They work closely with the organisation and focus on getting results.

Interim vs Permanent: What’s the Difference?

When organisations face senior talent gaps or changing priorities, they often choose between interim and permanent hires. Both play an important role, but they serve different needs. Here are the key differences to help you decide which is right for you.

Interim managers:

• Project-based roles
• Focus on specific outcomes, such as transformation or crisis support
• Higher daily rate, without the benefits of a permanent role
• More independent, less affected by internal politics
• Can usually start quickly

Permanent managers:

• Long-term roles
• Focus on team leadership and building culture
• Salary with benefits
• More integrated into the organisation
• Recruitment takes longer, but provides continuity

Interim professionals bring speed, focus, and a fresh perspective during times of change. They can help create stability and set things up for the longer term. Permanent managers build on this, supporting teams and guiding progress over time. Choosing the right type of hire at the right time can make a real difference to performance and stability.

Why Interim Management is Rising

The UK market has specific factors that make interim management more relevant.

• Ongoing pressure on leaders due to digital change and restructuring
• Strong governance and regulatory requirements, especially in FCA and PRA regulated sectors
• A competitive market where delays in senior hiring can slow progress
• A growing need for clear, independent decision-making and problem-solving
• Different contracting models, including PSC, umbrella, and fixed-term roles, influenced by IR35

IR35 plays an important role in how interim professionals are engaged.

• Outside IR35: Interims often bring structured approaches and a high level of experience
• Inside IR35: Umbrella or PAYE models can affect cost, onboarding, and how the role is seen

IR35 does not define the value of an interim, but it does affect contract setup, speed of hiring, and compliance.
