If you are shielding in line with public health guidance or required to stay home due to an individual in your household shielding and are unable to work from home, then your employer can continue to furlough you from 1 July so long as your employer submitted a claim for you in relation to a furlough period of at least 3 consecutive weeks taking place any time between 1 March 2020 and 30 June. This means the last day you could have started furlough for the first time was 10 June.
