Hi John,

In connection with the validity of the English Language tests the "Immigration Rules Appendix FM-SE: family members specified evidence" applies.
This document was updated 17 December 2015 and remains valid until the next update.

Here's the pertinent extract:-
32A. For the avoidance of doubt paragraphs 27 to 32D of this Appendix apply to fiancé(e), proposed civil partner, spouse, civil partner, unmarried partner and same sex partner applications for limited leave to enter or remain made under Part 8 of these Rules where English language requirements apply, regardless of the date of application. Paragraphs 27 to 32D of this Appendix also apply to spouse, civil partner, unmarried partner and same sex partner applications which do not meet the requirements of Part 8 of these Rules for indefinite leave to remain (where the application is for indefinite leave to remain) and are being considered for a grant of limited leave to remain where paragraph A277A(b) of these Rules applies. Any references in paragraphs 27 to 32D of this Appendix to “limited leave to enter or remain” shall therefore be read as referring to all applicants referred to in this paragraph.
