I was working from the UK for a year when I learnt out at Clench Common in Wiltshire as I was living out near Bath so I certainly appreciate the UK weather problems, although I'm sure Scottish weather was worse again!
Sounds like you should give Adrian @ Cloud Dancer a call, go for a TIF and make sure you like him, his aircraft etc and take it from there. Let him know you've done some flying previously too.
