I'm completing my CGT return in connection with the sale last year of my late Mother's property. I had always assumed that the cost of double glazing for this property, (which was done in the years 2000 to 2002), being a capital expenditure, would be allowable in reducing the tax payable. However, a recent call to HMRC produced the response that this is not the case, and that "improvements" only applied to such things as the building of an extension or garage. When I replied that we had not previously been allowed to offset this against rent received, the adviser said "you should have done", I was puzzled, as the relevant passages in the Taxation of Rents guide, IR150 state:
Capital Expenses:
(128) It is a general income tax principle that you can't deduct capital expenses in computing your taxable income.....
and
(145) Where a significant improvement arises from the change of materials, the whole cost is capital expenditure.......for example, if you replace single glazed softwood windows with double glazed PVC windows. the improvement element normally means that the entire cost is capital expenditure.
Am I missing something here? Surely, not having been able to offset against rent, I should now be allowed to offset against CGT. I haven't been able to find any definition of what constitutes an improvement in any HMRC document.
I emphasize that the work involved was a complete replacement of wooden single glazed windows with sealed double glazed PVC units.
Any help and advice would be appreciated.
