The symbol shows the location of the Plympton (Plymouth, England) transmitter which serves 35,000 homes. The bright green areas shown where the signal from this transmitter is strong, dark green areas are poorer signals. Those parts shown in yellow may have interference on the same frequency from other masts.
Are there any planned engineering works or unexpected transmitter faults on the Plympton (Plymouth, England) mast?

There is a problem with just channel 40. The strength of the signal drops at different points during the day. I
It seems to constantly drop around 21:30 and the signal strength is better by the morning.
This effects all stations transmitted on that channel. BBC1 is one of these channels which is okay offer switch over to HD station 101.
This isn't a problem but we dont get the local news in HD.

UHF Ch.40 is the BBCA/PSB1 multiplex carrying all the main BBC SD and Radio channels. Neither Free view or the BBC are currently reporting any problems with the Plympton transmitter and it's not listed for Planned Engineering.
As you have checked the other multiplexes and not seeing any problems with them it's highly unlikely to be a problem with your aerial installation, however it might be worth checking 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. Also check that your downlead looks undamaged (especially if it is old) and that your aerial seems intact and pointing in the correct direction.
Problematic connections, water ingress etc. can seem to affect reception of just an individual or several multiplexes.

To add to the above, if the problems continue, phone BBC Engineering Reception Advice (office hours) 03700 100123 They won't answer because of the current covid-19 situation but you can leave a message giving details of your issue, remember to explain the problem and checks you've done. Don't bother using their problem assistant it won't help with this issue.

Marcus Pasmore: thanks for your comments, tonight has been the same all okay until 9:30 ish and then the signal drops. Tonight I didn't turn over I just left if on and at 22:50 the signal strength came back for 10 mins and then dropped again 5 mins later.

This is beginning to possibly sound like some form of interference. Obvious candidates are central heating and lighting, the latter could be a faulty street light - but maybe 9.30 is a little late for that coming on - however it may need to be on for a while before it starts playing up, then there may be something visibly obvious - flickering etc.
Any form of discharge lighting in the house (or external lighting) fluorescent, compact fluorescent, some LED lighting can do this. Do you have any new electrical equipment, or something you don't always use that you are now? Anything with motors etc.
Check out those possibilities. Timing could point the finger more precisely. If it starts at exactly the same time each evening, it could be on a time switch.

Transmitter engineering: I have had rubbish Freeview TV reception from the Plympton relay transmitter for several days now, probably from about the time of the latest lot of engineering work, particularly on BBC channels. Is it possible something wasn't "plugged back in" or "switched back up" after this work?

I'm not sure what's given you the impression that there's engineering work going on at present. There's none listed for Plympton or Caradon Hill. The BBC aren't currently listing any faults, but if a new one has recently developed, there may be a reporting delay because of the current covid-19 situation.
There was some Tropospheric Ducting around several days ago which may have caused reception interference, but that cleared up a couple of days ago.
In the meantime, I would 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. See what signal strengths and quality you are getting for the multiplexes shown in your TV's tuning section. Also check that your downlead looks undamaged (especially if it is old) and that your aerial seems intact and pointing in the correct direction.
Problematic connections, water ingress etc. can seem to affect reception of just an individual or several multiplexes.
If you've done those checks and the problem remains on Monday morning, I'd give BBC Engineering a call on 03700-100123.

Hopefully you will have all your signals and programmes back now. The BBC have reported several issues at the transmitter throughout the day with a fault and essential engineering causing it to be off-air or on reduced power.
If you retuned at all when you had no signal, and haven't retuned since, you will need to retune again.
Retuning when there is no signal usually just clears all correct tuning resulting in the need for a further retune.
