CGT - deductible expenses

I checked the guidance, but am unsure about a few items. Could you please clarify whether any of the following would be deductible against CGT? 1. Initial mortgage arrangement fee when buying the property. 2. Legal fees for mortgage discharge from the land register when paying off my mortgage a few years ago. 3. The building factors organised essential, communal, structural works to the foundation of the building, gutters, and shared back court. These were part funded by the council. Some of these were works were additions/upgrades. Would those expenses fall under the deductible improvements category for CGT, or would they count as maintenance? Thanks for your help.

Hi,
None of these can be set against capital gain. They can only be set against rental income.
