I have the cost basis, so i do not have "neither".
Other than the 30 day rule, the acquisition date no longer affects the tax due. The return asks for it but if you leave it blank, as I always do, nothing happens.
...unless HMRC decides to investigate, which they do for a random sample of tax returns, and when they have suspicions. Nonetheless, if your numbers tally with theirs, you should not have a problem. As far as introducing indexation is concerned, I expect that it would be an indexation allowance that you can claim if you have the necessary records, and are willing and able to do the necessary calculations.
