easiest way to add a power point.

[rymatom]

how can i add a new power socket to an existing power socket. link them together so that i have an extra power point.

i don't want to have to dig out the wall. all cabling must be surface mounted. the extra power point will be a double socket and used for a tumble dryer and a chest freezer.

sorry about my earlier postings. i am new at this. i did not know that using capitals was offensive.

if this is the adjacent rooms question, you can drill through the wall behind the existing socket and put your new one on the wall in the other room
