Plumbers and heating engineers are definitely the most multi-skilled and versatile. In the course of their work, they have to carry out work in all of the above trades. Other trades are nowhere near. Eg. chippies - spend their days turning big pieces of timber into smaller bits and hammering nails through pipes.
