Headway Preston and Chorley: £6,095 from the Awards for All fund.
The cash will help run a project for people who have had a brain injury and find it difficult to make and keep relationships and friendships.
Project manager Liz Bamber said: “After a brain injury, some people lose their sense of identity.
“This has a huge impact on relationships with anyone, family members, colleagues, friends, and it can be really difficult for the person to come to terms with.
“So we have decided to run this project and it will equip the person with lost skills to help them re-form and retain relationships with people.
“There are five courses in the year run by a trained tutor and councillor.”
Speaking about the lottery funding, she said: “It’s a foot in the door for us which is fantastic to get another grant.
“We’re excited, it’s really good news.”
