I will present a recent calibration of the MAGPHYS spectral energy distribution (SED) modelling code that is optimized to interpret these UV-to-radio SEDs of dusty high-redshift sources. We derive statistically and physically robust estimates of the photometric redshifts and physical parameters (stellar masses, ages, star formation rates, dust masses) for the ALESS SMGs. Our modelling shows that our energy balance technique still successfully reproduces the observed SEDs in this highly obscured regime, and allow us to investigate the distribution of SMGs in the so-called ?star-forming main sequence? of galaxies. Finally, I will briefly describe preliminary results from newly-acquired ALMA observations of these sources.
