In most cases you can claim tax relief on the full cost of substantial equipment you have to buy to do your work. This is because it qualifies for a type of capital allowance called annual investment allowance.
Claim in a different way for small items that’ll last less than 2 years, eg uniforms and tools.
You can’t claim capital allowances for cars, motorbikes or bicycles you use for work, but you may be able to claim for business mileage and fuel costs.
If your employer gives you money for the item
Reduce the amount you claim tax relief on by the amount of money your employer gives you.
