[3] In 1916 he was admitted to the Privy Council[4] and appointed Chancellor of the Duchy of Lancaster in the war-time coalition of David Lloyd George,[5] a post he held until 1918.

In memory of his three dead sons, Cawley endowed a ward at Ancoats Hospital, Manchester, in 1919 at a cost of £10,000.

[9] In 1901 Cawley acquired the estate of Berrington Hall near Leominster in Herefordshire, which had previously been in the hands of the Rodney family.

[10] This was the family seat until 1957, when it was handed over to the government in lieu of death duties, and it is now in the care of the National Trust.

Lord Cawley died at Berrington Hall in March, 1937, aged 86, and was succeeded in the baronetcy and barony by his eldest and only surviving son, Robert.
