Okay, let’s tackle this. So Chris Gretton has 35 years of experience in finance, which is a significant amount. He has worked in various roles, including financial analysis, auditing, and management consulting. Location is London, England, which is a hub for finance and consulting. Industry demand for finance professionals with his level of experience is high. Average rates for finance professionals with similar experience in the UK range from $150 to $250 per hour. Considering his extensive experience and industry demand, I estimate his hourly rate to be around $200.
