I LOVE LUNG LEG. Slampt Records catalog for sure, arguably my favorite label of the '90s. Beyond the bands already mentioned (Sally Skull is dead-on), the closest to the Lung Leg sort of thing are probably going to be International Strike Force / Golden Starlet, Bette Davis & the Balconettes, Kenickie (early singles only), Pussycat Trash, Petty Crime.
Dick Johnson featured Jane & Philippa from Lung Leg, a little more garage-leaning but in a similar wheelhouse:
The A-Lines, maybe? They did a really great LP on Sympathy back in 2004 that's sort of adjacent, if Lung Leg had been affiliated with Billy Childish.
Not from the same time, but Tuff Enuff was a mid-2010s UK label working a very Slampt-influenced angle; the stuff they did for Woolf & Frau probably hits closest to that vibe. https://riotsnotdiets.bandcamp.com/
Another not-contemporaneous suggestion, but both of the Primetime singles ripped & had major Lung Leg energy: https://primetimepunx.bandcamp.com/
One more great neo-Slampt EP from a few years ago:
I'm sure I'll remember like a dozen other things as soon as I post this...
