In the United Kingdom, the depreciation rate for a motor vehicle depends on several factors, including the type of vehicle, its expected useful life, and its residual value.
For tax purposes, the UK government provides guidelines on the depreciation rates that can be used. These guidelines are often referred to as "capital allowances." The rates can vary based on factors such as the vehicle's CO2 emissions, its type (cars, vans, etc.), and the date of purchase.
As of my knowledge when I was in UK last year, the UK capital allowance rates for cars were as follows:
Vehicles with CO2 emissions of 50g/km or less: 100% first-year allowance. Vehicles with CO2 emissions between 51g/km and 110g/km: Main rate pool allowance of 18% per year. Vehicles with CO2 emissions over 110g/km: Special rate pool allowance of 6% per year.
