  We present a method for finding lines of constant physics in the confinement
phase of the SU(2) Higgs model on the lattice. The model is considered at
finite values of the cut-off where it behaves like an effective field theory
with three independent couplings. In particular, a renormalised quantity
sensitive to a variation of the bare Higgs quartic self-coupling is constructed
from generalised Binder cumulants. Numerical results for the non-perturbative
matching of the bare parameters of the model between beta=2.2 and beta=2.4 are
presented.
