You should retune your TV or box regularly – perhaps two to three times a year.
When you retune, your Freeview device scans for new channels or updates to existing channels, which means you're receiving all the channels available and getting the best out of Freeview in your area.
Before retuning, type your postcode into our Freeview Checker to see if any TV changes are scheduled in your area and which channels are affected.
How to retune
Many Freeview devices now prompt you to retune (rescan) when a new service launches or a change has taken place, and all you need to do is press 'ok' or 'retune'.
But if yours doesn't do this, you may need to manually start the retune. The process is straightforward – just follow our step-by-step retuning guide.
You might find that your channel favourites and scheduled recordings are also deleted after retuning, so you'll need to check and reset them. But any recordings you've made should still be there.
However, if your set top box or TV isn’t working correctly, you may sometimes need to clear its memory completely, or reboot it. If you have any problems, check your device's user manual, or get in touch with the manufacturer.
