Quite a few companies that I deal with can work that way. When you say far North - how far? North of teh Moray Firth? I am often up in the Speyside area - Cromdale, or over towards Huntly with quite a few friends up in Cullen and Buckie.
Thats the fitting/pipe that has to be held against (not moved) while tightening the back nut. to much movement and the washer pops off,sorry to say.
