Frequently Asked Questions

Common questions about interim vs permanent executive hiring

Hire an interim executive when you need immediate leadership (within 2-3 weeks), have a specific transformation project, are managing a crisis, or need coverage during recruitment. Choose permanent when building long-term capability, have 6-12 months to recruit, and need continuity for 3+ years.

Interim executives cost £1,200-£2,000 per day (£288k-£480k annually) vs permanent salaries of £150k-£300k. However, interims have no pension, benefits, equity, or severance costs. For 6-12 month needs, interims are often more cost-effective when considering total employment costs.

Yes, approximately 25% of interim engagements convert to permanent roles. This "try before you buy" approach reduces hiring risk. Conversion typically happens after 6-9 months when both parties see mutual benefit in a permanent arrangement.

Interim risks: higher daily cost, knowledge loss at engagement end, less long-term commitment. Permanent risks: 6-12 month recruitment time, wrong hire costs £500k+, redundancy liabilities, harder to remove underperformers.

Interim executives can start within 2-3 weeks, often faster in crisis situations. Permanent executives take 6-12 months to recruit, plus 1-3 months notice period. For urgent needs, interim is the only viable option.
