I assume you are UK domiciled (broadly, British).
At the dates any interest has been credited such amounts should be converted into sterling and shown on your tax return; any Dutch tax thereon could be used to offset any UK charge.
If the euros are transferred from Holland to a euro bank account in the UK, no UK tax arises at that time. If the euros are transferred into a £ bank account in the UK a possible CGT charge arises.
To calculate the CGT charge requires a conversion of the euros to £ at the date of transfer and a conversion of the euros into £ at the dates they were originally credited to the account (taking say average rates for the year); the sterling difference represents the UK capital gain (or loss). I suspect there will be no equivalent Dutch tax to offset the UK CGT (if any).
