The first Rector in Brampton Bryan was Robert de Lacey, in 1275. Since then, there have been just over 50 Rectors of St Barnabas. There have been several Rectories in Brampton Bryan over the centuries; one was certainly destroyed during the 1643/44 siege.

A Rector is a priest who was entitled to receive tithes, local taxes which used to be paid to him in agricultural goods (wheat, honey, wool, pigs etc) to support him. In 1615, a terrier, or survey, was taken of the Rector Thomas Peirson's house and all his property. It gives us a very clear picture not only of local agriculture at the time, but also what a comfortable life it was possible to lead in Brampton Bryan before the Civil War began just under thirty years later.

In 1800, being a Rector was still a well-paid post. By the early 20th century, things were very different. By 1937, the then Rector had to apply for a loan to a fund known as Queen Anne's Bounty, to repair the house that he lived in. Queen Anne's Bounty was set up by the Queen of that name in 1704 to support poor priests.

The current Rectory building was divided into two houses in 1949.
