The results of the search for the e⁺e⁻→η^γ process in the center-of-mass energy range from 1.075 to 2 GeV are presented. We analyze data with an integral luminosity of 746 pb⁻¹ accumulated with the SND detector at the e⁺e⁻ collider VEPP-2000 in 2010--2024. The η^→ηπ⁰π⁰ decay is used in the analysis, with the subsequent η and π⁰ decays into γγ. Upper limits not exceeding 13 pb have been set on the e⁺e⁻→η^γ cross section at the 90% confidence level.
