In December 1995 Derek moved to London and work in the world of television preparing the ITV National Weather and Channel 4 weather. He has also broadcast on GMTV's 'The Sunday Programme'.
After a year in London, Derek took a position at the Met Office headquarters in Bracknell as an Environmental Consultant. He returned home to Wales in 1997 and joined BBC 'Wales Today' where he has been the lead weather forecaster for over 13 years. As well as broadcasting the lunchtime, evening and late TV weather forecast, he also presents regular weather bulletins on BBC Radio Wales.
Derek has had a lifetime fascination with the weather and has presented a TV show ('Derek's Welsh Weather') and radio show ('Derek's Lightning Guide to Weather') on the subject. A keen walker, he has also had four series on BBC Radio Wales entitled 'Weatherman Walking' before the programme was converted into a popular television series. A new series of walks was shown on BBC One Wales in January 2011 and another is in the pipeline for 2012. His other TV appearances include 'X-Ray', a Welsh consumer programme, 'Jamie and Derek's Welsh Weekends' and 'The Big Welsh Challenge' a programme in which Welsh personalities are challenged to learn Welsh. He has also been a guest panelist on the BBC Radio Wales show 'What's The Story'?
On November 26, 2009, Derek had an appearance on BBC One in 'Gavin & Stacey' and has even been mentioned in the Sunday Times newspaper for his unique style presenting the weather. Derek has added yet another string to his bow with the publication of four books. Two walking books published by Lolfa and a children's book by Gomer called "Duck and Starfish". His autobiography 'Whatever the Weather' was released in October 2007.
Derek is particularly adept at interacting with the public and has a huge following of fans. As a measure of this modest man, Derek still finds it difficult to comprehend the way his popularity has grown beyond recognition over the last few years. He is in great demand as an 'after dinner speaker'; 'environmental speaker'; 'host'; 'compere' and general 'personality'. Wherever Derek appears his friendly, natural personality makes him a big hit with the young and old alike.
Outside of work, Derek's hobbies include walking, travel, learning Welsh, yoga, tennis and squash.
