I'm afraid it's down to current weather conditions -
They have been causing Tropospheric Ducting affecting much of the south coast and southern parts of the country on Saturday and now extending into the Midlands and North of the country through Sunday including East Anglia, now currently affecting Wales and England. This causes interfering signals from distant transmitters in Europe or the UK to affect reception of your wanted signals. This can periodically last, seconds, minutes and sometimes much longer - Do NOT Retune.
There is nothing you can do about this apart from wait for conditions to change, or use online streaming if available.
IF you did retune, you'd be best manually retuning the UHF channels for your transmitter as detailed at the top section of this page.
The BBC and Freeview have issued warnings -
High pressure weather conditions impacting TV & Radio services - from 07 October | Help receiving TV and radio
High pressure could affect reception across parts of the UK this week | Freeview
