Ackroyd's Victoria Cross was gazetted on 6 September 1917.
A medal investiture was held outside Buckingham Palace on 26 September 1917.
His widow Mabel and their five-year-old son Stephen received both the Victoria Cross and the Military Cross from King George V.
Mabel was devastated by her husband's death and she remained in mourning for many years afterwards.
On Mabel's death in 1947 the medals passed to their eldest son Stephen; on his death in 1964 they were inherited by their second son Anthony and on his death in 1988 by Ackroyd's grandson Christopher Edward Ackroyd, who was an orthopaedic surgeon.

The 1956 centenary exhibition of the Victoria Cross at Marlborough House displayed Ackroyd's medals.
After the exhibition the medals were given on loan to the Royal Army Medical Corps, although the originals were kept in the bank at Aldershot, replicas were displayed in the VC room at the corps headquarters Millbank, now the Chelsea College of Art and Design.
In 1993 Christopher Ackroyd decided once again to take possession of the medals.
The medals were handed over to the family in a ceremony on 12 April 1994 at the corps headquarters by the then Director General of Medical Services, Major General Frederick Mayes.
They were displayed in the orthopaedic surgery waiting room in Bristol.

After much discussion, the Ackroyd family decided to realise the value of the medals and approached Ackroyd's Cambridge College, Gonville & Caius, to see if they would be interested in founding a scholarship in Ackroyd's name.
Contact was made with Spink and Son and it transpired that there was interest from an anonymous purchaser: in April 2003 £120,000 was realised from the sale.

Negotiations took place with Neil McKendrick, the Master of Gonville & Caius College, and on 17 November 2003 an agreement was signed by Christopher Ackroyd and Neil McKendrick endowing a medical scholarship which would be awarded after the first year of the Natural Sciences Tripos and run for a total of four years.
In addition, an annual memorial lecture would take place in the Easter term on a scientific subject connected with medicine.
To date, eleven scholars have been appointed.
There have also been eleven memorial lectures given by distinguished scientists of whom at least six are Nobel Prize winners in their subject.

In 2006 it was confirmed that Ackroyd's medals had been purchased by Lord Ashcroft and would be displayed in a new purpose-built gallery at the Imperial War Museum.
In November 2010 the Lord Ashcroft Gallery was opened by the Princess Royal, and lilies of the valley were presented to her by Ackroyd's great-great-granddaughter, Mia Pearlman.
The collection now has at least 240 Victoria and George Crosses, with some belonging to the museum and some on loan.
