The county council and its partners are again running the Responders To Warmth (R2W) scheme this winter.
Practical support such as handy-man services are available.
To be eligible, residents need to live in Lincolnshire, have a combined household income of less than £23,500, combined savings of less than £10,000, and suffer with a chronic, acute or long term illness or disability.
Alternatively they need to be in receipt of a state benefit including Child Tax Credit, Pensioner Credit or income support.
A helpline and website is up and running until April 2013.
To access the service, or for more information, call 0845 606 4566 or visit www.responderstowarmth.co.uk
