Two weeks later, Havelock and the 14th Escort Group escorted a group of surrendered German U-boats from Loch Alsh to Lough Foyle. Havelock was detached to Home Fleet during the Norwegian Campaign and supported the Allied landings on 12-13 May at Bjerkvik during the Battle of Narvik. She continued to provide fire support during the battle for the rest of the month. Hambledon then operated on patrol and escort duty in support of Husky until being released from the operation on 31 July 1943 and reassigned to the 58th Destroyer Division based at Malta for patrol and escort duty in the central Mediterranean Sea. On 12 July 1940, increased German activity in the English Channel prompted the Royal Navy to transfer her work-ups north to Scapa Flow in the Orkney Islands, and she completed them there later in July 1940 and was assigned to a flotilla based at Sheerness, charged with patrol and convoy defence duties in the English Channel and along the east coast of Great Britain. In March 1942, Havelock became flotilla leader of Escort Group B-5 of the Mid-Ocean Escort Force and continued to escort convoys in the North Atlantic until early 1944. From 28 December to 14 January 1943, the escort group defended Convoy TM 1, a group of nine oil tankers sailing from Trinidad to Gibraltar.

Upon arrival in the United Kingdom in May 1944, Hambledon was assigned to the 21st Destroyer Flotilla at Sheerness, designated to escort assault Convoy G16 to the coast of Normandy for the initial landing and then to remain off the beachhead to defend it from German naval attack as part of Force G. In early June 1944, she joined the other forces allocated to Force G in the west Solent. In June 1943, the Royal Navy selected Hambledon for participation in Operation Husky, the Allied invasion of Sicily, and transferred her to the 58th Destroyer Division. Upon commissioning, Hambledon immediately began acceptance trials, which she completed successfully later in June 1940. She then proceeded to Portland for work-ups, during which she deployed with the British destroyers Atherstone, Fernie, Inglefield, and Imogen to escort the minelayers Menestheus, Port Napier, Port Quebec, and Southern Prince of the 1st Minelaying Squadron as they laid the first section of the Northern Barrage north of North Rona in Operation SN1. In October 1940, Hambledon was selected to participate in Operation Lucid, a plan to use fire ships to attack German invasion barges in ports in northern France, but bad weather forced the Royal Navy to abort the operation on several occasions and it was never carried out.

When convoy traffic along the east coast of Great Britain was reduced to free escorts for use elsewhere, Hambledon was selected for detached service in October 1942. Accordingly, in November 1942 she deployed to the North Atlantic Ocean to escort convoys bringing troops and equipment to Gibraltar for Operation Torch, the Allied amphibious invasion of North Africa, that month, and suffered slight damage from a torpedo explosion on 12 November 1942. In December 1942 she returned to her escort and patrol duties at Harwich, which in 1943 began to include interception of German S-boat - known to the Allies as "E-boat" - motor torpedo boats in the North Sea to prevent them from attacking Allied convoys.

On 7 October 1940, during operations related to Lucid, she suffered major damage to her after structure from the explosion of an acoustic mine in the English Channel off South Foreland at position 51°08′00″N 001°21′00″E / 51.13333°N 1.35000°E / 51.13333; 1.35000 (HMS Hambledon mined), losing one rating killed and two injured. Hambledon joined the other ships indian girl in london escort illuminating U-223 with searchlights and sinking her with gunfire at position 38°48′00″N 014°10′00″E / 38.80000°N 14.16667°E / 38.80000; 14.16667 (U-223 sunk) with the loss of 23 of the submarine's crew, leaving 27 survivors, but not before U-223 sank Laforey with an acoustic torpedo with the loss of 182 lives, leaving 69 survivors. Together with the destroyers Fame and Inconstant, the ship sank U-767 on 18 June. At some point, the ship was converted to an escort destroyer. After the landings were delayed from 5 June to 6 June due to bad weather, Hambledon departed for the landings along with the escort destroyer Albrighton on 5 June 1944 as escort for Convoy G16, which consisted of nine infantry landing craft and two rescue craft.
