The establishment of a lifeboat service in Selsey was in 1861 with RNLB The Friend; she was launched from the beach by means of skids.
For the station's first 25 years the lifeboat's Coxswain was James Lawrence.
On his retirement from the service in 1886 he was awarded a RNLI silver medal in acknowledgment of his long and valuable lifesaving service, highlighting rescues such as those of the brigs Governor Maclean (1875) and Sharah Ann (1871), the schooners Exel (1872) and Henrietta (1875), the barques Sueine Meinde (1878), and Tranmere (1883), and the schooner Kyanite (1881).
In 1925 work began on the construction of a new boathouse built on a piled platform with a gangway leading to it from the shore.
The gangway incorporated a trolley track.
In 1927 the boathouse was once more re-built to enable it to house the station's new motor lifeboat.

During the Second World War the station had a busy time.
The Watson-class lifeboat RNLB Canadian Pacific (ON 803) made many trips to rescue pilots from fallen aeroplanes and was launched on service 50 times.
In one rescue on 11 July 1940, the lifeboat saved the life of Squadron Leader John Peel, the commanding officer of 145 Squadron based at Tangmere.
He was forced to ditch his Hurricane (P3400) into the sea off Selsey Bill after sustaining damage in a fight with German Bombers.
Peel was in the water with just a Mae West life saving jacket, but he was pulled from the water by Canadian Pacific only minutes after ditching.
Canadian Pacific remained on station until 1969 and records show that she went on 286 services and rescued 157 lives.

In 1952 and into 1953 the boathouse's substructure was improved and strengthened and the slipway was lengthened.
In 1958 the boathouse was re-built as the old structure had become unsafe and unserviceable due to years of coastal erosion.
The new station was built with reinforced concrete and the deep water roller slipway was re-configured to have a gradient of 1:5.
The station was also given a new fabricated steel approach gangway from the shore.

In 1968 the service at Selsey was enhanced with the establishment of an inshore lifeboat rescue division.
This new service started in March of that year with the new lifeboat kept in a boathouse located by the approach gangway to the all-weather boathouse.
The inshore lifeboat was launched on a newly constructed gangway laid on the shingle beach to the eastern side of the main slipway.
The  first inshore lifeboat was a D-class lifeboat.
Further improvements were made to the inshore service with the construction of a new boathouse in 1987, the new structure including a new crew room, storeroom and a souvenir shop.

In 2011 the station celebrated its 150 years as a continuously active lifeboat station.
The occasion was marked by the RNLI by awarding the station as a whole an award on vellum which recognised the station's 150 years of dedicated service in the pursuit of saving lives at sea.

A brand new station was built onshore at the Kingsway, Selsey that allowed for the first time all elements of the RNLI at Selsey to come together under one roof on a single site, the new boathouse provides a fund raising shop, engagement spaces, access to the viewing gallery of the boat halls that hold the All Weather and Inshore lifeboat, a crew training room and offices, mechanics workshop and stores and for the first time a bespoke changing area for the crew.

On 1 April 2017, the station's Tyne class lifeboat Voluntary Worker was launched down the slipway from the boathouse for the final time, to be kept at moorings until it was replaced by the new Shannon class lifeboat during the summer, The Shannon is carriage launched from a brand new boathouse built on shore at the Kingsway, Selsey.

The old Slipway station was demolished and removed June–July 2017, and the seabed returned to its natural state.
Voluntary Worker was returned to Poole HQ in July 2017.

After intensive training the stations new Shannon class lifeboat Denise and Eric was placed on service July 2017, and officially named on 21 September 2017 at a ceremony
