Is a twenty mph limit legally enforceable?

[Tunku]

This is in Scotland, if that makes a difference. Our estate has recently been designated a twenty area, probably because of the two primary schools contained within it. I quite enjoy ambling up and down the main routes in it at 20 in third, but everytime I do, I attract the dreaded tailgater, usually elderly people in Micras and Yarises, or yummy mummys in large safe child transport vehicles, dropping off offspring at aforementioned schools. Some have even overtaken in a cloud of indignation, bouncing over speed humps and swooping around chichanes, blasting horns and exercising wrists in a peculiar fashion.
Me, I'm never in that much of a hurry when I'm in my neighbourhood. Every house on the main road through our estate has a driveway, and the main route has numerous cul-de-sacs to either side. It could be described as a fish spine in a large loop. Not a place to speed.
Either I'm underreading, or the locals are not too keen on the new speed limit.
Anyone know if twenty is enforceable by the police, or is it a council thing? Thanks for any insights.

if it is the number in black in a red circle, then it is legally enforceable, the 30 mph limit in town areas is upto, you don't need to travel at 30 mph all the time.

if unsure, visit your local plod station, assuming that it opens during the weekends or evenings as mine only opens during office hours and find the local plod website to be much more help

Number is as you describe, as is local police station.

I had a closer look at the signage. Entering it, it has a black 20 with a red circle with twenty zone written underneath. The other side has a grey thirty with leaving 20 zone written on it I think. There are speed bumps every few hundred yards, and twenty numbers painted on the roads.

well it looks as though it is legally enforceable - but it might not be if there is no TRO (in which case the signs are wrong but that wouldn't be a first)

Well I'll just stick to my twenty max then, and let the impatients get on with it. Could be fun if a jam sandwich turns up one morning
