Justin Welby succeeded Williams as the Archbishop of Canterbury on 9 November 2012, being enthroned in March 2013. On 26 December 2012, 10 Downing St announced Williams's elevation to the peerage as a life peer, so that he could continue to speak in the Upper House of Parliament. Following the creation of his title on 8 January and its gazetting on 11 January 2013, he was introduced to the temporal benches of the House of Lords as Baron Williams of Oystermouth on 15 January 2013, sitting as a crossbencher. He retired from the House on 31 August 2020 and from Magdalene that Michaelmas, returning to Abergavenny, in his former diocese (Monmouthshire).
