  The characteristic difference between a black hole and other exotic compact
objects (ECOs) is the presence of the horizon. The horizon of a classical black
hole acts as a one-way membrane. Due to this nature, any perturbation on the
black hole must satisfy ingoing boundary conditions at the horizon. For an ECO
either the horizon is replaced or modified with a surface with non zero
reflectivity. This results in a modification of the boundary condition of the
perturbation around such systems. In this work, we study how tidal heating of
an ECO gets modified due to the presence of a reflective surface and what
implication it brings for the gravitational wave observations. We also argue
that the position of the reflective surface, $\varepsilon$ $\gtrsim
\mathcal{O}(10^{-5})$, can have an observational impact in extreme mass ratio
inspirals.
