guarding the East Coast as part of 6th Provisional Brigade. In August, all the men of the Provisional Battalion were returned to their units except those who had not volunteered for overseas service. The Home Service men continued serving in home defence until 1916, when the Military Service Act swept away the Home/Overseas service distinction and the provisional battalions took on the dual role of home defence and physical conditioning to render men fit for drafting overseas. The 100th Provisional Battalion officially became the 29th (City of London) Bn, London Regiment (TF) on 1 January 1917. The battalion never served overseas, and was demobilised early in 1919. The 3/1st London Brigade moved to Bury St Edmunds, and was soon recruited back to full strength after the departure of the Provisional Battalion. It absorbed large drafts of recruits under the Derby scheme in February 1916, and in June it moved into camp outside Ipswich.

On 8 April the unit's title was changed to 4th (Reserve) Bn, London Regiment, forming part of the 1st London Reserve Group.
