That looks low to me but at least the openly advertised rates do seem to have taken a hit since COVID and the recent IR35 mess.

UAE has the advantage of being tax-free too, which adds ann extra 30%ish to take-home, although many people work very long hours. Also the weather is phenomenal 8 months of the year (although unliveable the rest), and your employer is on the hook to pay for exceptional health insurance. For a professional couple without kids, it can be a great way to save money, although costs are comparable to London.
