thanks, Hardy.
I am not clear WHEN the change to 29 occurs, if not Aug.
For some reason Tac does not reach here, except a couple of the muxes on a good day, whereas in Leiston it is quite good.

McMahon: Have you checked for any loose or damaged cables or connections behind your TV? Retuning will never fix a weak signal and can often make things worse by deleting the channels with weak/no signal making it harder to see when the fault has been fixed.

Mcmahon. you should be able to easily get BBC1 on uhf 44 or 47 (HD). Probably even with an indoor aerial . Note that the channels are now at the low end of the UHF frequencies so an old aerial may need to be changed for a wideband or group k aerial. If this is so you maybe eligible for help or aerial from freeview.

I do not think you will get the BBC mux from Sudbury on an indoor aerial as suggested by Hardy.
As you are probably aware, multiplex channel changes have been taking place as part of the 700Mhz band clearance, Sudbury had some changes back in March and whilst you initially may not have had (many) problems, further changes have been taking place more recently at adjacent and other transmitters and this is resulting in reception from Sudbury becoming more "difficult" for your location.
If you look at DigitalUK's prediction for your location at Coverage Checker - Detailed View you will see that for Sudbury this is not going to improve significantly as further retunes take place and will be worse for some muxes.
Also if you have a group E aerial this will not be helping as COM muxes move to lower channels.
However, there is a Relay transmitter at Clacton-on-Sea and whilst this is currently a "Freeview Light" transmitter (no COM muxes), that is changing on 1st August 2018 when COMs 4,5 & 6 will be added according to DigitalUK. You will see that on the link mentioned above.
You may get satisfactory reception from your existing aerial, but it may require re-aligning (or replacing with a group K).

Please IGNORE my previous post above, I'm afraid I mistakenly looked at the wrong postcode.
You should get satisfactory reception of all muxes according to DigitalUK, see Coverage Checker - Detailed View

Further to my last, there are 3 mobile phone masts close to you and almost line of sight between you and the transmitter. If any of them have recently started transmitting in the 800Mhz band they could be causing you interference, especially if you happen to have a distribution amplifier in your system.
Have you recently received a Freeview Interference card from AT800 by any chance? Even so, if you think it could be interference - apart from your reception problem, any blocky or frozen pictures on other channels, contact AT800 on 0808-1313800.
