Is there a correlation between the disruption and solar events, ie the Solar Wind, or Coronal Mass ejections? There's a page here from NASA that monitors Space weather.

The Kp Index is a measure of the total Earths geomagnetic activity. If Kp rises above 4 you get auroras at the poles. There appears to be, in the short couple of weeks ive been watching this, a loose correlation when Kp peaks and my satellite signal starts to pixillated

Good thought, but as the transmission satellites are on the Clarke Belt which follows the line of the Equator , polar clouds are very unlikely to cause transmission / reception issues.

As an aside, that´s why all satellite dishes in the Northern hemisphere look south and those in the Southern hemisphere look north. At the Equator the point straight up.

On my 1.8 dish no problems, don´t lose the signals other than high band ITV HD which are impossible to get in this area. low band ITV HD are receivable on some 1.25 ( sold as 1.4 ) dishes depending on exact location.
Yes, on a Freesat box changing the postcode will return ITV HD depending on dish size. If you have a 1.8m dish and cannot get, consult your supplier / maintainer as your dish could require to be re-aligned.
All ITV frequencies changed a while ago, SD variants can be restored by a rescan on free to air boxes, Freesat and Sky boxes should update on their own.
Cling film stops the bugs, but degrades quickly, use the white plastic stuff they use to protect most electrical goods in the boxes they come in. The newer clearer type can effect the signal, so not recommended.
I´m aware of the summer effect caused by the ionosphere but the recent drops twice a day are confusing me.

Oh! Nearly forgot, yes one part of an lnb can fail, but most likely a cable issue, check for inline joints or cable degradation.
