  We discuss how renormalisation group equations can be consistently formulated
using the algebraic renormalisation framework, in the context of a
dimensionally-renormalised chiral field theory in the BMHV scheme, where the
BRST symmetry, originally broken at the quantum level, is restored via finite
counterterms. We compare it with the more standard multiplicative
renormalisation approach, which application would be more cumbersome in this
setting. Both procedures are applied and compared on the example of a massless
chiral right-handed QED model, and beta-function and anomalous dimensions are
evaluated up to two-loop orders.
