That looks very much like a brown color morph of the Box tree moth (Cydalima perspectalis), which has been seen in the UK since 2008. The size is about right (around 4.0-4.5 cm wingspan).

This species is an invasive pest outside of its native range (Asia).

According to the Royal Horticultural Society this species has been invading the UK from the southeast with London a likely place to find them.
