Which companies have run the Channel 3 services in the Mendip transmitter area
If you've been having reception problems why on earth would you want to delete your correct tuning and retune, whatever the cause of your poor reception you are likely to end up with less channels tuned in if signals on some multiplexes are too weak for the receiver to decode!
Having said that, as you haven't given a full postcode we can't check the predicted reception for your locale which might be marginal on some multiplexes.
On a few occasions recently there's been some weather related "temperature inversion/tropospheric ducting" which has caused interfering signals from distant transmitters in Europe or the UK. This type of interference does not usually affect all multiplexes, it can last for seconds, minutes, hours, sometimes longer. Some predictions are suggesting there could be some during Monday. FM/DAB radio can also be affected.
Whilst there doesn't appear to be any faults, none are listed by the BBC or Freeview and no recent outages, the Mendip transmitter is now currently listed for Planned Engineering. It was last listed 4 weeks ago.

You are predicted to have excellent reception from Mendip in your locale. Considering your proximity to the transmitter, I'm suspecting an issue with your installation.
Where is your aerial?
For you, it should be pointing almost due W, bearing 274 degrees with the rods (or squashed Xs) horizontal. Have you checked the aerial looks intact and is pointing correctly?
If external, check your downlead is secure, looks undamaged, and isn't flapping in the wind.
Have you changed anything in your installation since the problem started?
Check you don't have any HDMI leads close to you aerial leads or flyleads. Aerial leads and flyleads that aren't quality double screened can suffer interference from HDMI, make sure they are as far apart as possible.
How old is your aerial and downlead?

Recent problems with Mendip too. BA2 5DF. Recently lost HD completely (Ch.35) for which my set was showing very low signal strength and high error rates (has subsequently come good but still sometimes glitchy). Ch. 48 also showing low strength and some errors.
I have an roof mounted aerial and am on high ground. It's connected to a suitable RF DA which all looks OK.
Am very close (<.5km) to multiple mobile masts which have recently been upgraded. Could that be relevant?
Would be most grateful for any advice!

You are predicted to get excellent reception from Mendip in your locale. Your problems are highly unlikely to be related to any of the mobile masts that you've mentioned. If there was interference from these masts it would be a consistent problem, not one that comes and goes.
If the problems were related to yesterday (evening primarily) and possibly some this morning, then it's most likely to have been the current weather conditions. There has been some Temperature Inversion/Tropospheric Ducting which has been disrupting signals in various parts of the UK for some.
Essentially it results in interfering signals from other transmitters in the UK or Europe reaching you and so your wanted signals are disrupted. It won't necessarily affect all multiplexes or necessarily at the same time if more than one. It can last for seconds, minutes, sometimes hours or longer.
Despite the incorrect spelling, this link does work - simple technical explanation
It's always possible these conditions may affect you again during the next 24hrs according to some current predictions but if they continue after tomorrow evening when they should have cleared, then it might be wise to make some basic checks.
I would check that your aerial seems intact and pointing in the correct direction (compass bearing 234 degrees for you, that's 9 degrees W of SW), and that your downlead looks undamaged (especially if it is old) and is secure and not flapping in the wind..
Also check all your coax plugs, connections, flyleads etc, unplug connectors check for corrosion or other problems and reconnect them. Flyleads are a common problem, try swapping/changing them.
Make sure you don't have any HDMI leads near unscreened/poorly screened flyleads/aerial leads especially if those aren't double screened coax as HDMI has been known to cause interference.
One other check you could do is to connect your aerial output direct to your main TV feed eliminating the DA in case that's playing up.
