I need to dig a whole for a post close to some laurel hedge which will mean cutting through some of the roots. Should I be worried and is there a best time of the year to do this?

The best time to do any root pruning on these shrubs would be during winter when they are not growing as vigorously. It won't really affect them much, anyways, unless you are cutting through the thicker roots near the base of the shrub.
Here is an article for more information on pruning these, which will also apply to any root pruning: https://www.gardeningknowhow.com/ornamental/shrubs/cherry-laurel/growing-cherry-laurels.htm
