The UK Part-Time CTO Market

The part-time CTO model (also known as fractional CTO) has become increasingly popular as companies recognise they can access senior technology leadership without the full-time cost. This creates opportunities for experienced tech leaders to build portfolio careers.

Unlike interim CTO roles which are full-time for a fixed period, part-time CTO positions offer ongoing engagement typically 1-3 days per week. Many fractional CTOs work with multiple clients simultaneously.

Who Hires Part-Time CTOs?

  • Startups - Companies building their technical foundation
  • Scale-ups - Fast-growing companies scaling their engineering
  • SMEs - Companies needing strategic technology leadership
  • PE portfolio companies - Businesses needing tech transformation
  • Non-tech companies - Organisations digitising operations

FAQ

Common Questions About Part-Time CTO Jobs UK

A part-time CTO (also called fractional CTO) is a Chief Technology Officer who works with companies 1-3 days per week on an ongoing basis. This model provides senior technology leadership without the full-time commitment or cost.
Part-time CTO day rates in the UK typically range from £900-£1,400 per day. For a 2-day per week engagement, annual costs are £90,000-£140,000 - significantly less than a full-time CTO package.
Most part-time CTO roles involve 1-3 days per week, with 2 days being most common. Many CTOs work with multiple clients to build a portfolio career.
The terms are often used interchangeably. 'Part-time CTO' emphasizes the reduced hours, while 'fractional CTO' emphasizes the shared/portfolio nature. Both refer to senior technology leaders working less than full-time.
Startups, scale-ups, SMEs, and PE portfolio companies commonly hire part-time CTOs. They get experienced technology leadership at a fraction of full-time cost - ideal for companies needing strategic technical guidance.
