Hi Jude, Your best bet is a Kango drill with a wide chisel bit attachment...you may be lucky and find it comes off quite easily with a hammer and crowbar or chisel but if not then buy or hire a mini Kango. Be careful about cables, check where the sockets are, they usually run in a straight line behind the skirting from the sockets, so be extra cautious there. Hope this helps Mostafa ??
