There is no expiation for missing days of Ramadan unless it was due to intercourse.

If someone is making up years of missed obligatory fasting does he or she also need to pay the compensation for each fast missed? Also if they have not made up fasts that have gone for years does the compensation be accumulative? Because the compensation may be very big and unaffordable for some people.

If someone does not complete their fasts from the previous ramadan before the next ramamdan comes do they have to also feed the poor for everyday that they delayed along with making up their fasts?

i live in uk where in coming ramadhan the fast will be almost for 19hrs, now due isha’ salah is very late it happens with me that sometimes I couldn’t wake up for suhur and woke up after fajr has begun, am I allowed to miss that fast and make up after ramadhan or do i have to keep it without eating anything?
