Dear Brother, May Allah Ta'ala reward you for your good intentions and may He bless you in your hijrah. Whoever migrates for the sake of Allah and His Rasool then his migration is for Allah and His Rasool. Brother, I live in England and I would personally recommend that you move to Dewsbury. It is has a very good Muslim community and there is also an established secondary Muslim Girls School - Zakariyya Muslim Girls School. There is also Dewsbury Darul Uloom. The primary schools in the area even though they are provided by the Government are very well adapted to providing services to a majority Muslim populace. In Dewsbury and its surrounding environs especially Batley it is very common to find Niqaabi ladies and insha'Allah you will not find too much difficulty. Also as Dewsbury in the North of England living expenses are not as high as they are in the South. There are also other areas in England such as Leicester, Blackburn, Preston, Bolton which has big concentrations of Muslims however I am aware more of Dewsbury. Other brothers from those areas could hopefully enlighten you further. I hope this has helped.
