The tiny parish of Frenze lies about 1 mile east of the market town of Diss, it is probably one of the smallest rural parishes in the county (so small its doesn't make it on to Phillimore's county map!). Frenze lies in lanes to the north of the A1066 road which links Diss along the Suffolk border to Bungay and is also next to the main Norwich to London railway line. There is little to the parish other than scattered farms and cottages plus its eponymous hall. The presence of church and hall together is often indicative of a "closed" parish where almost all landholding is controlled by the a single landowner and who restricts inflow of people; as a consequence a village doesn't develop. Frenze nowadays is probably most known by walkers as both the Angles Way & Boudica's Way footpaths pass through the parish and by the church. As for the future, given the expansion of Diss beyond the railway line it is perhaps inevitable that one day Frenze will be absorbed into the market town.

St Andrew's church lies at the end of a metalled lane which leads northwards from Dark Lane and sits amongst farm buildings and the hall. The church, which appears foreshortened because of the demolishing of the chancel (in 1820) merely consists of the remaining nave and a bell-turret. The nave windows show a 14th century origin but much else has changed over the years; the prominent porch is 16th century and the rest was heavily restored and re-roofed in 1900. The small size befits a parish of such tiny population.
