After returning to active service, Liverpool became subordinate to the 18th Cruiser Squadron at Scapa Flow and deployed in support of the Arctic convoys.
The conditions that Allied ships endured during the convoys proved extreme, with freezing weather, snowstorms, and frequent attacks by the Luftwaffe and Germany Navy.
Liverpool arrived in the Arctic as a replacement for the damaged cruiser Trinidad.
She joined Convoy QP 10, comprising 16 merchant vessels and five destroyers, on 12 April as an escort on its journey from the Russian Kola Peninsula to Iceland.
The convoy came under repeated attack from U-boats and aircraft for three days.
Four vessels were sunk (two of which sank on 11 April) and one was damaged; QP 10 arrived at Reykjavík on the 21st.

In mid-May, Liverpool joined a group of warships that was to have escorted Trinidad on her return journey to Britain.
After temporary repairs in Russia, Trinidad got underway on 13 May. The group that included Liverpool positioned itself west of Bear Island, in the Barents Sea, to rendezvous with the cruiser.
On 14 May, Trinidad came under repeated attack and was set ablaze by bombs.
The British had to evacuate and sink her the following day when the fire became uncontrollable.
Liverpool and the rest of Rear-Admiral Burrough's group came under attack themselves on the return journey.
On 25 May, Liverpool began escorting PQ 16, a convoy of 35 merchant vessels bound for Murmansk, the largest convoy yet undertaken in support of the Soviet Union.
PQ 16 had considerable protection, including the light and heavy cruisers Nigeria, Kent, and Norfolk, and numerous destroyers and submarines, with distant cover provided by the Home Fleet.
Inevitably, the convoy came under attack, beginning with a sortie on 25 May that damaged the freighter SS Carlton.
Sustained attacks from U-boats and at least 242 German aircraft yielded a total of seven vessels sunk on 26–27 May. The cruiser escort switched to the returning convoy QP 12 on 26 May.
Liverpool returned to the Mediterranean in June to participate in Operation Harpoon, part of the Malta Convoys.
While assigned to Force W covering convoy WS.19 on 14 June, Liverpool and the convoy came under attack by at least 38 Axis aircraft.
They crippled Liverpool and sunk the Dutch freighter Tanimbar, ultimately depriving the convoy of a close cruiser escort as Kenya and Charybdis were covering Force W's aircraft carriers when Italian ships attacked the surviving merchantmen and destroyers.
The torpedo that impacted Liverpool's starboard side hit the engine room, partially flooding the cruiser and disabling her machinery and steering gear.
Reduced to a speed of 4 knots (7.4 km/h), Liverpool had to be taken under tow by the destroyer Antelope.
For the rest of the day, Italian aircraft focused on Liverpool  rather than the convoy.
Before arriving at Gibraltar on 17 June, the group came under further air attack and Liverpool incurred additional damage due to near misses.
For Liverpool, casualties from the original attack were recorded in the ship's log as 15 killed and 22 wounded.
The fatalities from the torpedoing had remained in the engine room and been affected by heat exposure, requiring the distribution of an additional tot of rum to the volunteer retrieval party.

Liverpool received temporary repairs at Gibraltar and returned to Britain in August.
Although repairs at Rosyth were completed by July 1943, sufficient personnel would not be assigned to Liverpool until late 1945.
At Rosyth, Liverpool underwent an extended period of refitting and maintenance.
The refit upgraded Liverpool's radar equipment, removed "X" turret and the aircraft catapult, and enlarged the cruiser's defensive armament (which included an increase to 28 pom-poms, in six quadruple and four single mounts, seven Bofors 40 mm guns in single mounts, and the addition of five 20 mm Oerlikon cannons).
