What on earth is going on here then? Dodgy sensor or something?

That looks like some large temp drops in a very short time I cant see how the temp could change that quickly which woud make e think its a sensor fault, ty a new temp sensor see if the problem goes away.  ~~

Just set another print off and the temperature is steady up until it starts printing.  Seems like a loose connection is a possibility. Will take the bed off and have a look.  Need to work out if I can use a 3rd Party thermistor, the official one is £14

One comment I've found so far is it is "100k NTC 3950 HEX thermistor, JST XHP connector"

That's the common glass bead type thermistor cheap as chips  ~~

So the one I linked to should work?  There are cheaper options on ebay without connectors but hopefully that one would be plug and play

Gaza07

Yea the one you linked should work fine  ~~
