After the battle, "Invincible" made temporary repairs at Port Stanley and headed for Gibraltar, where she could be drydocked for more permanent repairs. This took a month, and the opportunity was taken to extend the height of her fore funnel by to reduce the amount of smoke blocking visibility from the bridge and spotting top. "Invincible" sailed to England on 15 February 1915 and joined the Grand Fleet. On 21 February, the British battlecruiser force was organised into three squadrons of the Battlecruiser Fleet, with the 3rd Battlecruiser Squadron (BCS) that was to consist of the three "Invincible"-class ships once "Inflexible" arrived from the Mediterranean. She was refitted between 25 April and 12 May to have four worn-out 12-inch guns replaced and the secondary armament reduced and given casemates. Rear-Admiral Horace Hood took command of the 3rd BCS on 27 May 1915 and hoisted his flag in "Invincible".
