Just to help people out until the site is updated:
Since 28-02-18 :
ARQA is now on channel 33 (was 56)
COM7 is now on channel 36 (was 33)
I do not know if LBS is still on Channel 51 - all other channels were not changed.
The listed 31st March 2018 change above is completely fictitious - there is no change due before April 2019 and even then those channel numbers are completely wrong.

Firstly, at time of posting there are no problems, faults or engineering work at Mendip.
As already mentioned by StevensOnln1, this page needs updating, but not just because of the recent Mux changes, there have also been one or two programmes Close and/or move multiplex in recent times (most of these often require some sort of retune). Now some specifics.
As already mentioned, there were some MUX changes on the 27th -
COM7 moved from UHF33 to UHF36.
ArqA (COM5) moved from UHF56 to UHF33.
LBS mux has not changed in anyway and is still on UHF51.
BrizzleRocker: MikeP has already responded to your remarks, he was not suggesting you climb up and fiddle with your aerial but check all connections (that you can easily reach). I fully endorse his comments, and those for future aerial requirements.
Bruce: Does your TV have an HD tuner and were you getting the COM7 Mux (eg. BBC News HD etc) before the MUX change? If you don't have an HD tuner you would not know, or if you have an HD tuner and couldn't get COM7 previously, then it's possible your aerial cannot receive UHF33 satisfactorily and you may need a new aerial. If all your aerial connections are fine, then it may be worth following a full Freeview Reset as sometimes with several changes some sets can get "confused" and not sort the channels correctly.
Comments to Bruce could also apply to anyone who can no longer get Pick, Dave & Sky News etc (ArqA - COM5) which is now on UHF33.
Fedup: Your problem could be due to a similar issue with your aerial BUT the reason you can get UHF33 on your older STB is because most STBs had greater signal sensitivity than a lot of more modern TV sets. This was because in the days before the full DSO, the digital signals were much weaker than now, most STBs were made to cope with this.
For those having problems with Welsh channels, then a Manual Retune may be the best option (you might have to do a full Reset with the aerial unplugged first to clear all memory). Look at your user manual to find out how to do these things (or look at the links on this site for a guide).
For those wanting to do a manual retune, the UHF channels are as follows -
UHF33 (ArqA-COM5), UHF48 (SDN-COM4), UHF49 (BBCA-PSB1), UHF51 (LBS) reception depends on location, UHF52 (ArqB-COM6), UHF54 (D3&4-PSB2). For those with HD tuners - include the following - UHF35 (COM8), UHF36 (COM7) and UHF58 (BBCB-PSB3).
For those wanting a list of Digital changes at Mendip, consult Freeview UK at Coverage Checker - Detailed View
To check reception at your own location, click on Change Address just below the big pink menu bar and then enter your postcode, make sure you have Detailed View ticked.

Hope you all find the above helpful.

North bristol. Bs34. UHF33 is now a very poor signal. Any idea why ?

Gary Colby: COM5 on UHF C33 is broadcasting at 100kW the same as COM4 & COM6 so the most likely explanation would be that you're using a Group C/D aerial which gives a poor response as C33 is outside of the frequency range it was designed to receive. If you contact the Freeview Advice Line (see link below) they'll arrange for someone to fit a new wideband aerial (free of charge if you don't have satellite or cable).

Gary Corby: Could you correct the postcode you entered into the site. It looks as though you missed the digit for the last part of the postcode as the terrain plot and Digital uk checkers think you are in BS3.
StevensOnln1 has provided the most likely explanation, however if you have an HD tuner and were receiving COM7 on UHF33 satisfactorily before the change on 27th Feb., then there may be another cause.

Since the re-tune we have lost ITV (inc Channels 3 - 8) through our LG Smart TV BUT we can receive these via our old Panasonic DVD. Have done auto and manual retune for 49, 54, 58, 48, 52 and 56. Any ideas most welcome. Thanks.

M Moppet: ITV/Channel 4/Channel 5 haven't changed frequency at Mendip yet (the PSB2 multiplex doesn't change until next year). Try retuning with the aerial unplugged to clear your existing tuning date, then plug it back and try a fresh retune.

Hi, I've been reading the pots with interest as we have lost all channels associated with COM5. I've replaced our aerial with a high gain wide-band, replaced the co-ax with new end connections. We've re-tuned without the aerial plugged in and re-tuned with the aerial lead connected. After all this expense and time we still can't receive these channels, getting frustrated now! We use the Mendip transmitter.
Any further advice greatly appreciated.

Adrian Pinsent:
Further to that said by StevensOnln1, I can confirm that COM5 is transmitting as normal from Mendip, we use Mendip as our main transmitter.
So please provide the requested full post code.
