Edmonds in BBC comeback after seven years out in cold.
The TV presenter will present a series of live TV specials beginning with a one-off National Lottery show.
Edmonds, 57, has not appeared on the BBC since 1999 when his Saturday night programme Noel's House Party was axed amid falling ratings. The acrimonious parting appeared to mark the end of his TV career.
But he made a triumphant comeback last year as the host of quiz show Deal Or No Deal, a ratings hit for Channel 4.
His first BBC1 job will be as the host of National Lottery Day on September 23.
The two-part, 90-minute show will celebrate the good causes supported by the Lottery.
Edmonds hosted the first ever Lottery show in 1994.
He said: "I relish the opportunity of once again hosting a major live TV event for the BBC, and look forward to developing exciting new programme ideas compatible with my long-term commitment to Deal Or No Deal."
BBC1 controller Peter Fincham said: "Noel is a presenter of immense talent and it is great to have him back on BBC1 - this marks the beginning of a new chapter between Noel and the channel. We hope he will present more innovative live TV specials."
Edmonds enjoyed a 30-year relationship with the BBC.
Noel's House Party, the show which introduced the nation to Mr Blobby, ran from 1991-1999.
After leaving the BBC he took a break and credits "cosmic ordering" with the resurrection of his TV career.
Earlier this year his performance on Deal Or No Deal earned him a Bafta nomination.
