For the NW, you've got Blackpool, Liverpool and maybe Harwarden as realsitic options. (Lit/ Licensed/FTO'ed). As you would not be done in one go you'd need to be able to drive home and need the flexibility about when the weather is bad as for the night flying components you need good vis.
Over this side you could fly before 8pm at Sheffield (low cost/ lit/ licensed) and probably also Doncaster although there are some restrictions at night at present due wrks, and I think Sherburn i E and Sandtoft.
If it is your machine (and it is night equipped) then you can take the instructor/ FTO of choice and the field of choice provided you have worked out the logistics of getting there and back for you both.
Choose soon. It will be too light otherwise!
