Structures and Buildings Allowances were introduced in the 2018 Budget and are available on qualifying expenditure incurred on or after the 29th October 2018.
To qualify it must be on new capital expenditure incurred on non-residential structures and buildings and can be deducted on an annul 2% flat rate basis.
On the 11th March 2020 HMRC announced that the rate will be increased to 3% from the 1st/6th April 2020. This increased rate will mean that it will reduce the time it will take to relieve qualifying expenditure from 50 years to 33 and one third years.
