The pipe that goes between the oil tank and the boiler (in my Aunts > house) is leaking.

seems odd that it's started leaking *somewhere* under 2 ft of presumably undisturbed ?? concrete and then tracking back to the tank
- perhaps more likely it's leaking whewre the sheathed pipe joins the valve at the tank and *appears* to be coming from a leak further on?
Did the guy do it originally? can't be that old if it's white plastic sheathed?? Has he quoted for replacing the whole lot perchance??
Have you tried checking whether the leak is coming from tank end or
*further* down pipe and tracking back? - bog roll twisted and wrapped round at various points (to absorb oil and so narrow down origin of leaks) is your friend........
