I have runners growing in my garden, and also on the allotment. The ones
from home are far more stringy and tougher than those on the lotty. Bean
seed from same packet, fed and watered the same. Only difference is the
soil. At home it's kinda average, on the plot, it's heavy clay. Is this the
reason for the difference?

No, if your runner beans are stringy and tough you are picking them too
late.

I would expect the clay soil to be more water retentive, and therefore
the home beans may well mature earlier and at a smaller size.
