Based on arXiv:1712.02229, I describe our application of integrand reduction to leading colour five-point amplitudes at two loops in QCD. Special emphasis is put on the integrand parametrisation with the aim of obtaining a compact representation at the integrand level. Using these methods we obtain benchmark results for the five-gluon amplitudes in the physical region as well as results for the fermion channels.
