St. Saviour's has twelve bells. Eight of these were obtained from St Mark's Church, Leicester, UK. They were restored at the bell foundry of John Taylor at Loughborough, UK. The eight bells were baptised, in the grounds of the Cathedral, by the Archbishop of Canterbury and installed ready to ring by October 1988.
In 1985 a grant was received from the Bicentennial Authority to enable the completion of the tower and spire and to install bells which were included in the original design by Edmund Blacket in 1871.
In 1993 two more bells, Golden Grove and Fishburn were added to the top of the bell ring to give the Cathedral a ring of ten bells. The final two trebles, Endeavour (see photo below) and Borrowdale, were added in May 2005, thus completing the Peal of twelve bells.
Ringing tower bells requires training for several months. The bells swing through a full 360° so that they can be rung in a specific order. The ringer must control the swing of the bell so that they ring in the correct place. Bellringers do not ring by a musical score but by numbers. Special sequences can be rung so that every combination of the bells are rung.
The Service Bell is named Mesac, after the first Bishop.
