With rapid response capabilities, and a daily planning of its observingschedule, the Neil Gehrels Swift Observatory is ideal for monitoring transientand variable sources. Here we present a sample of the 12 novae with the mostdetailed ultraviolet (UV) follow-up by Swift -- the first uniform analysis ofsuch UV light-curves. The fading of these specific light-curves can be modelledas power-law decays (plotting magnitude against log time), showing that thesame physical processes dominate the UV emission for extended time intervals inindividual objects. After the end of the nuclear burning interval, the X-rayemission drops significantly, fading by a factor of around 10-100. The UVchanges, however, are of a lower amplitude, declining by 1-2 mag over the sametime period. The UV light-curves typically show a break from flatter to steeperaround the time at which the X-ray light-curve starts a steady decline frommaximum, ~0.7-1.3 T_SSSend. Considering populations of both classical andrecurrent novae, and those with main sequence or giant companions, we do notfind any strong differences in the UV light-curves or their evolution, althoughthe long-period recurrent novae are more luminous than the majority of theclassical novae.
