Vanguard, the eighth ship of that name to serve in the Royal Navy, was ordered on 6 February 1908.
She was laid down by Vickers Armstrong at their Barrow-in-Furness shipyard on 2 April 1908, launched on 22 April 1909, and completed on 1 March 1910.
Including armament, the ship cost about £1.6 million.
Vanguard was commissioned on 1 March 1910, under the command of Captain John Eustace, and assigned to the 1st Division of the Home Fleet.
She was present in Torbay when King George V visited the fleet in late July.
Vanguard also participated in the Coronation Fleet Review at Spithead on 24 June 1911 and she trained with the Atlantic Fleet the following month before beginning a refit.
Captain Arthur Ricardo relieved Eustace on 23 September.

The ship was recommissioned on 28 March 1912 and rejoined the 1st Division shortly before it was renamed the 1st Battle Squadron on 1 May. She participated in exercises with the 1st Fleet in October.
Vanguard was refitted in December, with new bilge keels being installed.
On 5 June 1913, Captain Cecil Hickley replaced Ricardo upon the latter's promotion to commodore, second class.
