  We give a Wong-Zakai type characterisation of the solutions of quasilinear
heat equations driven by space-time white noise in $1+1$ dimensions. In order
to show that the renormalisation counterterms are local in the solution, a
careful arrangement of a few hundred terms is required. The main tool in this
computation is a general integration by parts formula that provides a number of
linear identities for the renormalisation constants.
