From Langley admissions.
Quote:
Applicants must be resident at that address on the closing date for the Common Application Form on 31st October 2020 and have been continuously resident at the same address since 1st May 2020, ie six months prior to the closing date for the Common Application Form. The school may check the authenticity of the address stated; proof of residence or further information may be requested and must be provided.
So bear that in mind if you were thinking of applying to Langley as they have priority areas. Moving in now won’t make any difference.
