On the North side, the Organ fills the former Lady Chapel. Originally placed on the northwest wall, it was moved to its present position presumably in the nineteenth century. The instrument was blown manually and a record exists that the Organ was cleaned and overhauled in 1924 for the sum of forty-nine pounds, seventeen shillings and sixpence, including the altering of the blowing handle position.
In 1967 the Organ was rebuilt and the console (Ensemble of manuals at which the player sits) was detached and placed near the southeast wall.
On the South side, there is the attractively carved Parclose Screen separating the Chancel from the South (Merle) Chapel. The painted wooden roof of the Chancel dates from the mid-nineteenth century, with a floral design including stars over the Sanctuary.
The Communion Table in the Sanctuary is the focal point of the church; where in response to our Lord’s command “Do this in remembrance of Me ” the Service of Holy Communion is celebrated. It was for this Service that St Andrew’s was built. The theme of the Communion Rail kneeler is Unity; the unity of God, the Church and man. The design is linked throughout with a brown thread in a Celtic design, uniting the flowers and the symbols. The flowers depicting the arts are from the works of Shakespeare. St Andrew’s cross is repeated in the pattern, as is God the Holy Spirit in the dove and the Holy Trinity in the three fishes. In the centre is ‘Christ the King’ a symbol of the Chi Rho and crown. On either side is an original monogram of the letters UNITY with the I and T forming a cross.
On the South wall of the Sanctuary is an unusual and elaborate double Piscina (literally: fishpond, a form of drain to take rinsings from vessels used during Holy Communion). It is thought to be over seven hundred years old.
Above the Piscina is a window in the Decorated style of the fourteenth century. It depicts the four Patron Saints of the British Isles: St George, St Andrew, St Patrick and St David, which contrasts with the style of the window on the North side of the Chancel.
There are burial chambers beneath the floor of the Chancel and the former Lady Chapel; their date is uncertain. Brass plates from graves beneath the Nave are restored on the pew ends.
