Before switchover began, around one quarter of the UK public could not receive Freeview, because the digital signal was broadcast at low power in order not to interfere with analogue television. By switching the analogue signal off, it became possible to increase Freeview coverage. When switchover was completed, 98.5% of UK homes were able to receive the service. Extending Freeview involved re-engineering work at 1,150 transmitter sites across the country between 2008 and 2012. Digital UK was responsible for co-ordinating this work, which was carried out region by region. Suppliers Digital UK also worked with electrical manufacturers and retailers and promoted the 'digital tick' logo, a certification mark for the public that identifies TV equipment in stores that will work before, during and after digital switchover. Switchover Help Scheme Digital UK worked alongside the BBC-run Switchover Help Scheme, which helped older and disabled people convert one of their sets to digital. Previous shareholders Until March 2021, Arqiva was a shareholder of Digital UK, but was asked to stand down by the other shareholders at the time. Arqiva subsequently went through a process of restructuring.
