Worcester City have decided not to extend their groundshare agreement with Kidderminster Harriers.
They have been based at Aggborough, home of neighbours Harriers, since leaving St George's Lane in 2013.
City had hoped to build a 3,000-seater stadium after selling their 108-year old home, but plans fell through, and subsequent proposals for a ground in Perdiswell have not come to fruition.
Worcester have yet to announce where they will be playing next season.
"Aggborough is a first class venue in which to play football and one which we leave reluctantly," said chairman Anthony Hampson.
"However, as a board we have to look at the long-term viability of Worcester City.
"It is clear that, with on-going delays surrounding our return to Worcester, remaining at Aggborough is unaffordable to us in the long term."
