Okay, let’s tackle this. So Simon Hill has 46 years of experience in power and cooling systems, which is extremely long-term. Typically, professionals with such extensive experience can command higher rates. However, considering his role at BT, a large and established company, and his skills, I would estimate his rate to be on the lower side. Average hourly rates for power engineers in the UK range from £50 to £150, depending on experience and industry. Given Simon’s extensive experience, I would estimate his rate to be around £75 per hour, which is at the lower end of the range.
