Chris:
Firstly plkease check all your aerial connections, cables and the plugs/sockets by unplugging them and refitting. If the issue continues it is most likely to be the current high pressure area.

Looking at the Digital UK Coverage Checker at Coverage Checker - Detailed View shows you should have good reception of all channels.
That suggests you may have a problems mwith your aerial system. So please check all the cables and connections. Unplug all coaxial plug/sockets and refit. Then recheck the signal strengths for the various multiplexes broadcast to you location.

A full post code would help us determine what the signal reception conditions are like at your location. The Digital UK Coverage Checker requires that fiull post code as it does not use village/town names as they are not specific enough.
If trees are blocking the signal from the ground-based transmitter then the obvious option is to use Freesat instead. That uses a satelite in geostationary orbit and can be received using a conventional dish and Freesat receiver (that equipment is very different from that used for Freeview).
Freesat carries most of the channels that are available via Freeview, there is no subscription needed either. Do not be misled into thinking it is anythiong to do with Sky Television and do not have a SkyQ LNB fitted to the dish.

Look at the top of this page! The LCNs used do not generally change between transmitters. Whatever is on LCN 1 at Sandy Heath is also on LCN 1 at Chrystal Palace, Hannington, Dover, Black Hill, etc. It is only the multiplex channel (frequency) that changes between transmitters.
I also suggest that you check the signal strength as too much causes similar problems. Yopu ideal want between 60% and 85% strength, higher or lower often give problems of b=picture break up or sound loss, or both and often intermittently.

There are many changes in the pipleine and one is to move multiplexes down the frequency spectrum. In addition, there are two temporary multiplexes, COM 7 and COM8, which are broadcast on channels 55 and 56, so Sutton Coldfield is no longer only a Group B service. To get those viewers need the ability to receive those channels that are in the Group C/D range so they need a wideband aerial as a Groupd B is not able to get all the channles and neither is a Group C/D aerial. The best solution is a wideband type or a log-periodic that can get all the current channels as well as those planned for the next several years.

I didn't miss the point as ALL transmiters provide the available programmes on the same LCN no matter where they are broadcast from. So the list I suggested is exactly the same as that suggested by Paul - the pnly difference being that Paul's suggestion was headed Sandy Heath. But as they are all the same it made no difference at all.
I agree that talkin g about 'channels' gives rise to an ambiguity, hence we regular contributors try to refer to the multiplexes bei g on a specific channel, meaning the frequency, and to the programmes as being on a certain Logic Channel Number (LCN). That has been the habit here for at least the last ten years that I have offered advice here. Other contributors largely do the same so we are at least consistent.
As to you problem, have you checked the reported signal strengths, especially for those services that are giving problems?

Clevedon Resident etc:
There are no known faults at the Mendip transmitter. There are two possibilities. One is that there could be a poor connection in your aerial system, so please check all the cables and connection. Unplug all coaxial plugs/sockets and refit to clear any corrosion/oxidation on the contacts.
Another possibility is that you have too much signal;. Please check the signal strengths on all multiplexes (strength and not quality). It shoudl ideally be between 60% and 85%. If it is more then you have too much signal and it needs to be reduced. If it is less then you need a better aerial (preferrably a widband type or a log-periodic) to receive more signal.

B Daniels Mr:
Please don't publish other people's contact details on a public forum. It is highly dangerous and unwarranted. Especially if it is done without the express permission of the individual concerned.

tony powell :
You are predicted to get excellent reception from Sandy Heath, which is just 34 km away. There is no reported faults at that transmitter. So please check your aerial system, checking all the cables are undamaged and that all connections are in perfect order. Unplug all coaxial plugs/sockets and then refit. Then check the signal strength shown for all the multiplexes. You should ideally have between 60% and 85% for all channels. If it is stronger then you have too much signal and it shoyld be reduced with an attenuator. If it is too low then you need a stronger aerial, a wideband type or a log-periodic.

A Full post code is needed not a partial as you have given.
