Thanks for the tips guys. Its been okay so far 1 week in. No night time wimpering and nothing chewed or spoiled. They like their crate too
I've been off so they've been under surveillance outside the whole time. We've been out and left them for a couple of hours too so they're ready for when the new term starts. My mum will be their lunchtime walker so they're not going to be left for more than 3 hours at a time. They do seem to sleep more than they're awake.
Two different personalities I think Bolt will be more of a handful and he's not as soppy as Spike, however I intend to be on the case of both of them. They haven't been on furniture so far which I intend to enforce. Spike fell in the water feature last night, fortunately I was right next to him so grabbed him straight out. He wasn't bothered but enjoyed the warm rinse and blankie afterwards, see photo below.
Spike
Bolt
Post swim comfort. Bolt genuinely seemed to try to help, he stopped chewing Spikes ears for a change and seemed to offer buddy warmth. this shows Bolt sleeping on his back which he seems to like.
