All households with children of school age to get 2 rapid COVID-19 tests per person per week
Whole families and households with primary school, secondary school and college age children, including childcare and support bubbles, will be able to test themselves twice every week from home as schools return from 8 March.
Instead, families should access tests via their own employers if they offer staff testing, by attending a local test site, by collecting testing kits from a local site or by ordering them online, the DfE said.

As with the tests for pupils, testing of family members is encouraged, but not mandatory.
I can't see many families trying very hard to obtain tests.
