Answer: It isn’t strictly dependent on whether the flat is a ‘separate legal entity’. HMRC will take that into account, but are more concerned with the physical circumstances.

If the flat is and always has been quite separate from the rest of the house as occupied by your father, then the flat and the rest of the house will be treated as two separate assets.
A gift of the flat will be treated as a disposal of the flat by your father at current open market value. This will give rise to a gain measured as the difference between the value at the date of the gift, and the open market value of the flat on 31 March, 1982.
An estate agent should prepare those valuations and must understand that they are needed for tax purposes.
If the flat is integral with the rest of the accommodation in the house, which from your description seems unlikely, then if your father gifts the flat to you he may be able to claim at least a partial exemption in relation to the capital gain though maximum relief is only £20,000 of gain.
The calculations can be quite complex and your father should seek advice from an accountant or other tax adviser on his likely tax exposure.
