DEAN Davies successfully met an energy efficiency challenge - and won a mountainbike.

The 11-year-old, from Catterick Garrison, took part in a contest organised by British Gas, designed to teach youngsters about how people use and waste energy in the home.

Dean, a pupil at Le Cateau Primary School, is one of only 20 youngsters from across Britain to be picked as a winner.

His prize is a Raleigh mountain bike, and a pack of accessories.
