Carl Lewis:

You should never retune when you have interference or loss of signal due to that, or Planned Engineering or transmitter faults that cause pixellation or no signal. In most instances this just clears the correct tuning of the affected multiplexes and you end up with nothing or tuned to the wrong (more distant) transmitter.
If you are correctly tuned, do NOT retune it serves no purpose.
The only instance where a retune may be suggested (usually advised by an on-screen pop-up) is where a commercial operator changes one of their channels on one of the COM multiplexes. If you happen to be in an "awkward" reception area then a manual retune on the UHF channel(s) for the affected multiplex(es) is usually the best suggestion.

Your predicted reception at your locale is not the best, although it could depend on where you are within your postcode as it could be variable, even poor or good! for some multiplexes.
This is because you might receive signals from other more distant transmitters (and there are several in parts of Devon, Cornwall, also parts of S.Wales) that use the same frequencies and in normal conditions it wouldn't be a problem. Matters will be made worse in weather conditions that enable the TV signals to travel a lot further than normal - we have had such conditions of late. When there is very strong "Tropospheric Ducting" even signals from Europe can be received (see How does good weather affect my television? | Help receiving TV and radio and the links on those pages for a simplistic explanation). Not all multiplexes will be affected at the same time or for the same lengths of time. A lot of aerials have "side-lobes" which can receive signals from directions other than the one the aerial is pointing.

Checking that your aerial is intact with no missing elements, is pointing in the correct direction (bearing 314 degrees - NW at your locale) with the rods (or squashed Xs) vertical.

The best thing to do will be to do a Manual retune for Kilvey Hill as follows - first, unplug the aerial and do a full automatic retune. This should clear all previous (and incorrect) tuning.
Plug the aerial back in, and in the TV's tuning section, do a manual for each UHF channel -
For Kilvey Hill it's C21, C24, C27, for the PSB1/BBCA, PSB2/D3&4, PSB3/BBCB HD multiplexes and C25, C22, & C28 for the COM4/SDN, COM5/ArqA & COM6/ArqB multiplexes, also C34 for the Local (Swansea) multiplex.
(C means UHF channel).

You may have to repeat that procedure a few times whilst/if interfering conditions persist over the weekend which some predictions suggest.
