Parents in my DC's class have just announced they are moving into a rental property while they have some work done to the house they own and usually live in. This happily coincides with the Secondary School Application window and fortuitously puts them in catchment for a previously out-of-reach 'outstanding' school.
Clever things timing the renovations in this way! But a quick look at our County Schools Admissions website reveals: 'Examples of cases that will be fully investigated and applications withdrawn include: renting a property close to a popular school but retaining another property'.
Seems pretty clear but they're confident that a 12 months lease will give the Council all the comfort it needs - and another family pulled off a very similar move last year. Maybe this rule doesn't actually get enforced?
