The unfinished west end of the chapel, which had remained bricked up since 1978, was completed in the summer of 2021 with the addition of an open three-arched porch designed by Michael Drury, following a successful fundraising campaign by the Friends of Lancing Chapel.

The chapel was closed to visitors during the coronavirus pandemic and, subsequently, during the completion of the west end porch and refurbishment work on the school kitchens opposite, reopening to the public on 25 April 2022.
