I will only be burying a short length of SWA (less than a metre) below
ground where it goes from the cable run under a path and into the
garage.

From the electrical suppliers (Coventry) where can I buy a short length
cut from a roll for a few pence ?

There is a roll in my barn:-)

You could hover outside your nearest cable supplier and beg some from
the first white van that turns up.
