I give myself 20-30 years as a cycle and see what happens. By that time, I will be much older.
Parts of Bucks such as High Wycombe already has an established Muslim community. So in some cases, Sikhs who move in some of these parts are the newcomers whereas the Muslims are older community.
Muslims who live in these types of towns, moved into council housing and have their own enclaves where the town is still mostly goreh, however Sikhs who move to these kind of towns are typically part of a middle class.
I think you are safe in Bucks for the time being, but they will try their luck there eventually. Looking back I should have bought in Richings Park but my thoughts about schooling and my family situation at the time meant I bought here.
The outside Slough primary schools might be an option, I will see how the demographics develop in this area in the next few years. I wouldn't want to carry on living here if more and more of them move in.
Where do you live if you don't mind me asking.
