Andrew Thomas talks to electrical contractor Martin Barker about how to ensure you do not overload your electrical systems this festive season Christmas is definitely the season to make everything sparkle. Christmas trees, living rooms and dining rooms will be brightly decorated and more and more people are choosing to festoon the outside of their homes and gardens with dizzying arrays of lights and projections.
