Capital Gains when selling foreign shares

Over my my working life I was periodically given company shares (UK resident working for an American Company). They are all now in a lump sum controlled by Interactive Investor. If I were to sell some, above £3000 (equivalent) how would the CGT be calculated?

OK, who/where can help determine gains (as per the link), when shares bought at different times are now combined in one lump sum? Thank you.
