Para E-ECP.3.4. of the IMMIGRATION RULES APPENDIX FM: FAMILY MEMBERS determines that an applicant applying to join a family member in the UK (e.g. a spouse or child dependant) will have to provide evidence that there will be adequate accommodation, without recourse to public funds, for the family, including other family members who are not included in the application but who live in the same household, which the FAMILY OWN OR OCCUPY EXCLUSIVELY: accommodation will not be regarded as adequate if-
(a) it is, or will be, overcrowded; or
(b) it contravenes public health regulations.
Section 324 of The Housing Act 1985 determines whether or not accommodation is overcrowded.
Two tests are applied which are referred to as the ‘room standard’ and ‘space standard’ These tests look for instance at whether children over 10 of the opposite sex will have to share a room and whether the number of people sleeping in the property exceeds that permitted by the Housing Act 1985.
