These windows by Hardman were mostly installed after the church was opened between 1857 and 1877. The exception being the one beside the pulpit whose subject is that of the Bishop of Milan bringing communion to the sick during the 1576 plague of Milan, which was one of those originally installed. The next was on the subject of the Death of St Joseph which was installed in 1857, and dedicated to Iosephus Knight. This was the Joseph Knight that had built the church, and is also commemorated in the east window. A brass plaque (since removed) noted that he died 16 days after the church was consecrated.
The remaining windows were all installed between 1872 and 1877, which is after the death of John Hardman (1867), but the Hardman company supplied them all. The first of these on the south wall is a representation of St George, and is dedicated to Georgina Mary O'Conor (1872). Next to it is a representation of the popular medieval subject of St Anne teaching the Virgin to read, a medieval version of this subject can be found at Stanford on Avon. This window is a memorial to Mrs Mary Perry and her three daughters who were nuns.
On the north wall there are two lancet windows of 1877. The first of these has three figures that represent the Apostle St Thomas with a carpenter's square and the inscription "My Lord and my God", St Helen with a cross and the inscription "No salvation except through the cross", and St Aloysius with the inscription "What will it avail me for Eternity". The final window is a representation of St Helen, and one should compare the two different treatments of the same subject, it is dedicated to Miss Ellen France who was a contributor to the building of St Peter's church in Leamington Spa.
