24 Month rule

This is a HMRC policy that states that once you have been made aware (i.e you have a contract to state) or you have been based at a specific site for more than 24 months this is no longer deemed as a temporary place of work and hence you are not entitled to claim business expenses (hence reduce the tax you pay). This is deemed by the HMRC as irrelevant who your employer is, it is the location that is important. i.e. you can’t change umbrella organisation to avoid this and hence continue to off-set expenses.
