Neutral pion and η$$\eta $$ meson invariant differential yields were measured in non-single diffractive p–Pb collisions at sNN$$\sqrt{s_{\mathrm{NN}}}$$  = 5.02 TeV with the ALICE experiment at the CERN LHC. The analysis combines results from three complementary photon measurements, utilizing the PHOS and EMCal calorimeters and the Photon Conversion Method. The invariant differential yields of π0$$\pi ^{0}$$ and η$$\eta $$ meson inclusive production are measured near mid-rapidity in a broad transverse momentum range of 0.3 4 GeV/c$$\hbox {GeV}/c$$ at 0.483±0.015stat±0.015sys$$0.483 \pm 0.015_{\mathrm{stat}} \pm 0.015_{\mathrm{sys}}$$. A deviation from mT$$m_{\mathrm{T}}$$ scaling is observed for pT<$$p_{\mathrm{T}}<$$ 2 GeV/c$$\hbox {GeV}/c$$. The measured η/π0$$\eta /\pi ^{0}$$ ratio is consistent with previous measurements from proton-nucleus and pp collisions over the full pT$$p_{\mathrm{T}}$$ range. The measured η/π0$$\eta /\pi ^{0}$$ ratio at high pT$$p_{\mathrm{T}}$$ also agrees within uncertainties with measurements from nucleus–nucleus collisions. The π0$$\pi ^{0}$$ and η$$\eta $$ yields in p–Pb relative to the scaled pp interpolated reference, RpPb$$R_{{\mathrm{pPb}}}$$, are presented for 0.3
