I agree with DesignNomad RE toning down the CV. I think there’s a couple of threads on here with people talking disparagingly about star/thermometer ratings for trying to highlight competency levels.
As for applying for jobs some good positions occasionally come up on Coroflot (although it’s mainly US based) also try Dezeen and Adrem. Adrem will arrange a pre-interview meeting with you where they could give you advice if required.
There are also a number of places just outside of London that have designers over my ten years of living in London of worked outside London for around seven. As you’re heading in the opposite direction to most people you’ll get a seat on the train everyday and if you’re working half an hour out of London you’ll still be getting to the pub at around the same time as your mates who’ve had to travel across London after work.
