I totally agree with you, but to keep pretending like you’re still living in UK you have to commit few crimes here and there. AFAIK all UK banks except for HSBC and international branches of high-street ones only work with residents and tend to ask you about residency from time to time.

It’s not like you can’t do it, but you need to consider consequences especially when OP only ILR and he is not actually UK citizen.

Come here to post it, but yeah. Oracle Cloud always free tier is great.

Using it for many years and there simply no competition here.

Your best long-term solutions are:

• Setup Ltd in the UK and get hired as contractor with B2B contract. Then pay all your taxes properly in whatever country you actually reside.
• Get your company hire you through service like Deel that handle taxes on it’s own since they just legally hire you in whatever country you reside in.

Both options wont be suitable for majority of employers, but at least you won’t be on the hook for tax fraud in EU with some hefty fine to pay.
