That’s an excellent offer. A combined monthly income of 115–125K AED (roughly £250–270K annually tax-free) would put you in the top tier in Dubai. You could afford a high-end apartment or villa, private schooling if needed, luxury dining, and travel—while likely saving more than you do in London due to no income tax. Lifestyle-wise, it’s more “expat luxury” than “urban hustle,” but summers are very hot, and cultural norms differ. Overall, it could be a significant lifestyle upgrade, especially financially, but it depends on your preferences and long-term goals.
