Hi,
There is no list of what is allowable and what is not, when it comes to capital expenses.
This means that we can't confirm one way or another if something is allowable.
We can point you to the guidance, so that you can decide for yourself if the cost is allowable.
CG15150 (
CG15150 - Expenditure: introduction) onwards.
For example, replacing a roof is considered general maintenance and for capital gains purposes is not allowable, however, if the roof was changed to include windows, the purpose of the roof has changed and the cost is allowable.
Unfortunately, you will have to decide what is or isn't allowable.
Thank you.
