I'm in Chippenham too, and have also been without BBC channels since the retune. I have a combination of Samsung and Panasonic equipment. I have done a factory reset on the TV with no change.
Are we simply to expect that this is how things will be? It's a bit galling to see "This transmitter has no reported problems" at the top of this page, the powers that be clearly aren't reading anything below it.

Well you guys are the best. Having vented my frustration, I read the previous posts in more detail and have resolved my issue.
In my case it was being caused by an old freeview box that I hadn't disconnected inhibiting the passing of the BBC A channel. I've now taken I out and all is well. I should have done it when I installed the Freeview TV that made the old box redundant but there was a Rugby match coming up and I was in a hurry...
It may be that changing the output of the old box would also have done the trick but as I didn't need it at all, I didn't explore the option.

I've had no access to BBC and whatever is on that 698 Mhz chl - for most of them I'm getting 0% strength but 40% qual. I'm using EyeTv so it is so hard to try to bring any suggestions on this board to any useful conclusion on my Mac.

In response to bsk, I also use EyeTV on a Mac. I have found it crashes quote a lot at the moment (a problem I never used to have) and when it does, it seems to go back to the old channel settings. If I do a complete and full re-scan of the channel list I am now getting BBC progs again. There is probably an old and buried file list I need to throw away. It is still annoying.
However my neighbour has a Ferguson F1603LVD2 tv that won't pick up the BBC channels either. Does anyone know how to do a factory reset on that?

I'm in Brislington in Bristol and have my tv connected to the main roof aerial. Have retuned manually, automatically and have reset my Samsung Freeview 3D tv about 5 times and nothing works, I can only get ITV1&2, C4, C5, C4+1, ITV1+1, More4 and E4. Not a hint of other channels especially BBC. I've even tried using the other nearby transmitters just in case and emailing digital UK, who were no help at all. I'm getting fed up of it now.

ChrisE: How about your reception of COM4 (ITV3 etc) on C48?
Some others who have poor or no BBC reception now have poor or no COM4 reception, when they did before.

I am in a dip at BA3 5XU. Roof top arial (But fairly old)
Since 27th March BBC channels from Mendip arial has been a problem.
Humax freeview box. BBCA channels are found on C49 (698.0MHz) but reception is poor and freezes a lot. Signal strength is ~75% but quality is is erratic. Average 50% but varying 40-80%
C54 ITV etc has good reception. Signal strength ~82% and quality 100%
Also appear to have problem with SDN C48 group. (these channels not found in auto search)
Channel strength and quality (manual tune) is same as BBCA.
Have tried removing any old set top boxes with no improvement.
Any ideas please? How can I tell if it's arial related?

Having re-read all these posts again, I wonder if the problem is too much signal overloading the tuner. I have signal monitoring facilities which tell me I have 99% signal strength and 100% signal quality. Much more signal and the quality would drop, possibly to zero. The frequency change could result in a stronger signal thus turning good reception into bad. Where I am (near Taunton race course) there are no buildings nearby in my line of sight to the transmitter.
