Lorry driver expenses

If a company pays a lorry driver, who is an employee, an industry scale rate payment of £26.20 for overnight stays, can they also provide tax-free benchmark scale rate payments for other days based on journey time, ranging from £5 for 5 hours to £25 for 15 hours (and ongoing at 8 pm)? Additionally, is it permissible for the company to pay benchmark scale rate payments in addition to the industry scale rate payment?

Hi QQask,
No, you cannot pay Benchmark rates in addition to the industryscale rate for lorry drivers.
The agreed rates for Lorry rivers £34.90 or £26.20 if they use a sleeper cab are the maximum amounts that can be paid free of tax and National Insurace under the agreed industry scale rate.  
Thank you.
