This is a tax on skilled trades. Office-based workers don't pay a tax on the use of the office.
Currently home-based field service engineers lose £3000 of their tax allowance because they have access to a company vehicle which is treated as a benefit.
What is not taken into consideration is that a van is actually a mobile workplace without which they cannot do their job, not a luxury.They have no choice as to whether or not they have a van, it is a requirement in order for them to carry all the tools and spares necessary.
Previously, as long as there was not private use there was no tax charge, which was fair.
