WILLIAM PALMER: The predicted reception at your location suggests that, subject to there being no local obstructions (trees, tall buildings etc) in the signal path, you should have a good signal available from Wenvoe.

As per the post before yours, bottom of p18, the transmitter was off-air on Friday for essential engineering. If you retuned when you had no signal (never recommended), it'll probably have cleared your correct tuning.
As there are currently no fault reports by the BBC, try a manual retune of UHF C35.
