£75,000 in Jersey doesn't go as far as in UK.
Housing - average cost of a 3 bed semi c£430,000.
Cost of living - generally 10 - 15% higher than in UK.
ATCU - getting back to how it used to be; which was" brilliant" - after a grim period under an ex CAA Ops Director & NATS SATCO who were both dire.
Quality of life - generally a lot better than a UK city. Depends what you like though. Outdoor & safe environment. Good place to bring up kids. A little isolated at times. Can be expensive to get off island.
No National health - you have to pay. £40 per visit to doctor.
Good education standards - comparable to upper third of UK standards.
Very good pension.
Income Tax - 20% of taxable salary. You will end up paying approximately 17 - 18 % of your gross salary.
I never regretted coming back after life at LATCC & EGPD. But, you might miss certain aspects of UK life.
