On 6 November, "Thunderer" was sold for scrap to Messrs, Hughes, Bolckow & Co. for £66,150. She was too deep in draught to enter their scrapyard in Blyth and so was partially stripped down at Rosyth. Even so, she grounded at the Blyth harbour entrance on 24 December. After she was refloated on 30 December, she went back to Rosyth to be further lightened, as her draught was still too deep to allow her to enter Blyth. She was towed from Rosyth on 12 April 1927 and reached Blyth two days later to finish demolition.
