Clare Manager Colm Collins says his talented side have earned a higher standard of football.
The Banner will play in Division Three next year, after a low-scoring win over Antrim in Creggan.
The game stood 0-04 to 0-02 at half-time, but Clare closed out a 0-10 to 0-06 win despite playing into a strong wind after the break.
Next up for Clare is a League Final meeting with Tipperary in Croke Park in three weeks’ time, but promotion is secured regardless of the result and Collins says his men deserve it.
Elsewhere , Cork will now face Dublin and Mayo will take on Derry in the Division 1 semi-finals.
