The UKIRT Infrared Deep Sky Survey (UKIDSS) Large Area Survey (LAS) has thenecessary combination of filters (Y, J, H and K), depth (Y <~ 20.2) and areacoverage (~4000 deg^2) to detect several redshift z >~ 6.4 quasars. The ThirdData Release (DR3) included ~1000 deg^2 of LAS observations which have so faryielded two previously known z ~= 6 quasars and two new discoveries: ULASJ0203+0012, at z = 5.72; and ULAS J1319+0950, at z = 6.13.
