Further to my previous reply to you at Sandy Heath (Central Bedfordshire, England) DAB transmitter | free and easy for 21 years I've been doing some further research.
A number of very adjacent postcodes to your locale, have received postcards from https://restoretv.uk/
It seems that you may have not, but that does not mean that you aren't suffering interference problems from a new/upgraded mobile phone mast.
Contact them on 0808-1313-800 and explain that you are having persistent problems with your Freeview reception and that this has been happening now for a couple of months and that you understand that neighbours in adjacent postcards have had postcards. Can they please send you a Free Filter.
In the meantime, the HD channels at Sandy Heath are on UHF Channel 21, so try a MANUAL retune of C21 and as previously mentioned make sure that Automatic Retuning on your TV is turned off if possible.
Once correctly tuned, do NOT retune.

Chris.SE: Hi Chris, I have read all of your messages but, today the pixilated pictures on BBC HD channels today are making the viewing impossible. I am talking with Panasonic about the tuning problem where the TV is not designed to disable Auto tuning. I have infact been speaking to them for 3 weeks and, will be speaking to them tomorrow. I feel these TV'S are sold under the banner of Not fit for purpose.
Kind regards,
Ian Jackson

Ian Leslie Jackson:
I agree with you that sets where you cannot disable automatic updating/retuning are a pain in the proverbial when engineering, weather conditions or even faults on your own aerial system my result in brief periods of no or weak signal. Panasonic should be able to provide a firmware update to add this functionality.

Sandy Heath is currently listed for Planned Engineering as noted further up the page. That's the most likely cause.

Like others, in Cambs Ely region/CB6, HD multiplexes have been unwatchable evening of today/26th.
Seem to be no SandyHeath maintenance mentioned on the map at https://ukfree.tv/extras/…ing.
If there were a new 5G inteference problem would this be so intermittent ?
(I've not yet looked for a site that lists new local mobile masts/transmitters)

4g mast locations seem to be shown at

but, for Cambridgeshire, does not show which of them may have also had 5G services turned on
