We analyze an adaptive boundary element method with fixed-order piecewise polynomials for the hyper-singular integral equation of the Laplace-Neumann problem in 2D and 3D which incorporates the approximation of the given Neumann data into the overall adaptive scheme. The adaptivity is driven by some residual-error estimator
plus data oscillation terms. We prove convergence even with quasi-optimal rates. Numerical experiments underline the theoretical results.
