St Andrew's Church was built on Church Road in Portslade-by-Sea between 1863 and 1864. It was designed by Brighton-based architect Edmund Scott. In 1898 it was given its own parish, but this has now been united with the parish of St Nicolas. The combined parish covers the whole of Portslade-by-Sea and Portslade Village, and extends some way on to the south face of the South Downs. As from September 2013 the status of St Andrews was changed to a Chapel of Ease and now will be only used occasionally for religious service.
