For a second-order parabolic equation, we consider a problem with oblique derivative and impulsive action. The coefficients of the equation and the boundary condition have power singularities of any order in the time and space variables on a certain set of points. We establish conditions for the existence and uniqueness of the solution of the posed problem in Hölder spaces with power weight.
