As his status nationally rose through judicial preferment, Bromley was able to shift and consolidate his regional power. He became a Justice of the Peace in the Marcher counties of Gloucestershire, Worcestershire and Herefordshire during 1540–1. At the succession of Edward VI his importance in government reached a stage where the recordership of Shrewsbury was no longer appropriate and he relinquished it to Reginald Corbet, another Hill ally. By this time he had been appointed Custos Rotulorum of Shropshire, the senior post in the county's civil government. By 1552 he had joined the Council in the Marches, the regional representative of central government in much of Wales and the border counties.
