I grew up on the Lancashire/Yorkshire border, so I used to use a mish-mash of both, e.g. eh-up, ta-ra, be reyt, mithering, mardy, maungy, can't be doing with X, daft ha'porth, sun's crackin' flags, put wood in t'hole, addled, dancers (stairs), cloth ears, X has a cob on, cruckle, scran, ginnel, demic, you're not as green as you are cabbage-looking, Shanks' pony, owt or nowt?, couldn't stop a pig in a ginnel, you look like a house end in that! (i.e. massive), gipping, Bobby Dazzler, si'thee (usually as in, if you buy something of good quality, it will "si'thee out!" i.e. last until you die), chuffin 'eck/'ell, kecks, skriking, put big light on, picking and piking, 'tis like Blackpool Illuminations in 'ere, tha won't feel the benefit (if you didn't take your hat or coat off inside), were you born in a barn?
There are probably many more, but as I have moved away, I have had to replace them with the more general English equivalent (if there is one!), but still trip up and have to explain things. However, eh-up seems to be the one that has stuck!
