Santander has completed its takeover of TSB, a move that shocked the City last year and significantly bolsters the Spanish-owned bank’s presence in the UK. The near £3bn mega-merger is now final, propelling Santander up the nation’s retail banking league table. As the dust settles, we examine the major players in the sector.
Lloyds Holds the Crown
Despite a flurry of mergers and acquisitions and persistent challenges from disruptors, Lloyds remains the UK’s largest retail bank. The blue-chip finance giant, which includes Lloyds Bank, Halifax, and Bank of Scotland, serves approximately 26 million customers and holds around a fifth of the mortgage market. Its dominant position makes it a prime target for competitors. Revolut’s first advertisement after securing a licence featured Graham Norton riding a horse to mock Lloyds’ black horse branding, while Nationwide has encouraged members to switch from Lloyds as the group closes branches.
Nationwide’s Virgin Money Acquisition Boosts Its Standing
Nationwide’s takeover of Virgin Money sparked controversy among its members but elevated the building society to a top spot in retail banking. Before the tie-up, Virgin Money, founded by Sir Richard Branson in 1995, was the sixth-largest UK bank and listed on the FTSE 250. The deal created the second-largest mortgages and savings group behind Lloyds and ahead of NatWest. The mutual now has around 16 million members and customers and has consistently won in the current account switching war, recording its highest net gain of 64,257 in the final three quarters of the year.
Santander Swings with TSB
With the TSB takeover complete, Santander has become the country’s third-largest bank for current accounts and fourth for mortgages. The bank added TSB’s five million customers, £34bn in mortgages, and £35bn in deposits. Announced last July, the deal saw Santander beat out rivals like Barclays, which banking analyst John Cronin said would be “sore that it didn’t manage to seal the deal,” though pricing may have been the deciding factor. Other recent consolidation includes Barclays’ £600m acquisition of Tesco’s banking arm last year, which enabled a £700m share buyback, and HSBC’s renewed partnership with M&S Bank in 2024.
