[4] The church's fortunes changed with the development of the Brunswick estate and other residential areas around the old village in the early 19th century.

[2][3] Construction of the Brunswick estate began in 1824 and St Andrew's Church in Waterloo Street was built to serve it in 1828 (as a chapel of ease).

[3] A different kind of change in the church's fortunes came about following formation of The Brighton General Gas Light Company in 1825.

Although production of coal gas was notorious for the smell it produced, the company acquired a two-acre site in the fields between Hove Street and St. Andrew's Church, and in 1832 built a gasworks there.

Due to spiralling demand a large new works was opened in Shoreham Harbour at Portslade-by-Sea in 1871, and by 1885 all gas manufacture in Brighton and Hove had been transferred there.

Due to the increases in population parish officials realised that a rebuilding of the original St Andrew's would be needed to provide enough capacity.

He quoted £1,870 exclusive of internal fittings and his fee, both of which were just over £50 His father, a Brunswick estate resident, ultimately paid the latter.

[8] Local maps show that in 1844 the church was centred inside a roughly square site, probably less than two acres in area.

By 1873 the northern boundary had moved as far as the residential development in Monmouth Street (now demolished) the churchyard being a long rectangle with an area several times that of the original site.

Although the whole of the exterior was rebuilt, some original Norman-era parts were retained inside, and possibly influenced George Basevi's design decision.

[10] A series of round columns, pointed arcade arches and parts of the roof survive from the mediaeval era.

The watercolour artist Copley Fielding, who lived in Hove in his later years, was buried in a tomb in the northeast corner of the churchyard after his death in nearby Worthing in 1855.

Sir George Everest, the geographer who undertook the Great Trigonometric Survey in India while acting as Surveyor-General, was the first person to determine the exact height of the world's highest mountain, which was then named after him.

However, Sir George himself had no connection with Hove or Brighton at any time during his life, and none of the family members buried at the church were known to be associated with it.

[13][14] George Augustus Westphal was the last surviving naval officer who served on The Victory at Trafalgar and is buried in the churchyard.

Another Trafalgar veteran, Rear-Admiral Sir John Hindmarsh KH RN, the first Governor of South Australia, lies here too.
