The Old Hall, in Billingborough, has been awarded for being among the top care homes in the East Midlands.
The home came 17th out of 1,582 homes in the East Midlands.
The top 20 received a certificate and will be highlighted on leading guide carehome.co.uk, which runs the awards.
The awards are based on recommendations received from residents and family/friends of residents during 2014.
The home made the top 20 in the East Midlands in 2014 as well.
Karen Culy, manager of The Old Hall, said: “We treat our residents as we would our own families.”
A coffee morning recently held at the home raised £250 for Dementia UK.
