We present the discovery of three new transiting giant planets, first detected with the WASP telescopes, and establish their planetary nature with follow up spectroscopy and ground-based photometric light curves. WASP-92 is an F7 star, with a moderately inflated planet orbiting with a period of 2.17 d, which has R$_p$ = 1.461 plusmn 0.077R$_J$ and M$_p$ = 0.805 plusmn 0.068M$_J$. WASP-93b orbits its F4 host star every 2.73 d and has R$_p$ = 1.597 plusmn 0.077R$_J$ and M$_p$ = 1.47 plusmn 0.029M$_J$. WASP-118b also has a hot host star (F6) and is moderately inflated, where R$_p$ = 1.440 plusmn 0.036R$_J$ and M$_p$ = 0.514 plusmn 0.020M$_J$ and the planet has an orbital period of 4.05 d. They are bright targets (V = 13.18, 10.97 and 11.07, respectively) ideal for further characterization work, particularly WASP-118b, which is being observed by K2 as part of campaign 8. The WASP-93 system has sufficient angular momentum to be tidally migrating outwards if the system is near spin-orbit alignment, which is divergent from the tidal behaviour of the majority of hot Jupiters discovered.
