The largest centipede found in UK was at about 9 inches long (about 23cm with 2 cm wide) by Mr Aaron Balick. then, someone in venezuela claims to have seen a centipede about 18 inches long (about 45,72cm). but just because humans have seen/caught centipedes this long, it doesn't make it the largest!
Beside that Centipede there's another huge centipede species that was found in Australia, it was ethmostigmus rubripes species which can reach about 16cm length. It is found in both dry and moist habitats, usually in sheltered places such as under logs, leaf litter and bark, and under rocks. It is solitary, terrestrial and a nocturnal predator. It is common throughout Australia, the Solomon Islands, New Guinea, Indonesia, Southeast Asia and China
Among all Centipede Species, it's the south american species named Scolopendra Gigantea "white-legged morph" ("Goliath Centipede") which is also listed as one of the biggest centipede species, Their head bears long antennae, jaws, and two pairs of maxillae used for food-handling.
