Vic Reeves and Bob Mortimer will be awarded The Writer's Guild of Great Britain Award at The British Comedy Awards later.
Mortimer said: "I'm really proud that Jim and I have always written our own guff. It's great to have that recognised."
Cuba Gooding Jr, Louis Smith and Joan Collins will be handing out awards.
It will also be revealed who has won the outstanding achievement award, voted for by fans.
Alan Carr, Sarah Millican, Lee Mack, Graham Norton, Jack Whitehall and David Mitchell have all been nominated.
Comedy pair Reeves and Mortimer have written and starred in several programmes together on TV since 1990, including The Smell of Reeves and Mortimer and quiz show Shooting Stars, which aired intermittently between 1993 and 2011.
Reeves said on hearing the news: "I am most cock-a-hoop over being awarded this most prestigious of trophies."
The ceremony will be broadcast on Channel 4 from 21:00 GMT.
