After she had worked as a secretary to an ENT specialist and as a bank clerk,[2] her husband persuaded her to consider a career as a model, which proved to be successful.
The popularity of the gas board campaign led to Secker's being offered a role as a continuity announcer and newsreader for Tyne Tees Television in 1976.
When continuity from Newcastle ended in 1996, she made a permanent move to programming, presenting breakfast news bulletins and the magazine show Tonight, alongside her own series, Kathy and Co. Secker also contributed features for the nightly news programme North East Tonight before leaving Tyne Tees in 1998.
In 1994, Secker became a presenter on BBC Radio Newcastle, hosting a Sunday afternoon dedications show.
