As a UK based pilot you only pay UK tax and NI on a PAYE basis like any other UK based employment. If you want to move overseas you can at any point, but will change to a 'continental' contract where you pay 20% tax to Portugal, UK NI, and then it depends on where you live and what agreements are made betweeen Portugal and your country of residence. Most places (not Denmark!!) have a double-taxation agreement so there is no more to pay.
Regarding pay in £ or €, your choice. You can change as often as you want, so if you can be bothered to track exchange rates you can make a bit more.
The flying is great, the roster - once published on the 15th of the month for the following calander month - doesnt change, and pay is fine

. Dealing with some of the depts in Lisboa can be very frustrating
