While serving in this office he was invited to England by the king, William Rufus, who appointed him abbot of Ramsey Abbey.

[4] He received the appointment having paid the king a sum of £1,900, as part of a deal in which Herbert's father was made Abbot of New Minster, Winchester.

[6] In addition to Norwich Cathedral, Losinga was responsible for founding St Margaret's Church in King's Lynn; the Church of St Nicholas in Great Yarmouth; and Norwich School.

Losinga visited Rome for a second time in 1116, representing the king in a dispute between the monarch and Anselm, the Archbishop of Canterbury.

It may have been on the return journey that he fell severely ill at Placentia (modern Piacenza); other sources suggest he suffered this illness on a possible third journey to Rome, which he did not complete, instead awaiting his fellow ambassadors at Placentia, before returning to England with them.
