On 15th December, 2017, two stained glass windows were installed in English Martyrs, Didcot. The windows were made by John Hardman Powell, the artist who made the stained glass windows for the House of Commons. The windows were purchased from English Salvage and are believed to have originated from a private chapel in Cambridge. They needed considerable restoration which was expertly carried out by Chapel Studios of Kings Langley, Hertfordshire who, with local window installation company Primefit, installed the panels in their new frames in the church. The project was financed largely by the Living Our Faith fund. They were blessed by Bishop Philip at Vespers on 16th February, 2018.

The windows depict (on the liturgical south side of the church) Saints John Houghton, Robert Lawrence and Augustine Webster and (on the liturgical north side) St Edmund Campion. ​​
