We present the latest results from the UKQCD/RBC collaborations for the Kl3 form factor from
simulations with 2+1 avours of dynamical domain wall quarks. Simulations are performed
on lattices with two different volumes and four values of the light quark mass, allowing for an
extrapolation to the chiral limit. The analysis includes a thorough investigation into the sources
of systematic error in our ts. After interpolating to zero momentum transfer, we obtain f+(0) =
