Lloyds Banking Group has cemented its position as the most complained-about name in British financial services, racking up more grievances with the City regulator than any other lender during the second half of 2025, as the wider sector handed nearly a quarter of a billion pounds back to disgruntled customers.
Fresh figures from the Financial Conduct Authority show the FTSE 100 banking giant fielded a hefty 187,516 complaints across its subsidiaries between July and December last year. The black horse brand itself bore the brunt, accounting for 90,837, while its Edinburgh-based commercial arm Bank of Scotland was not far behind on 79,508.
The scale of the figures partly reflects the sheer footprint of the group, which counts roughly 28 million customers and remains the country’s biggest financial services provider. Santander, which serves around 14 million Britons, came in a distant second with 124,919 complaints.
Despite the eye-catching numbers at the top of the table, the wider picture is one of relative stasis. Total grievances across the industry edged up to 1.9 million, a rise of just under one per cent on the first half of the year and broadly consistent with the trend that has prevailed since early 2021, when figures have fluctuated between 1.7 million and 2 million.
There was, however, a measure of good news for the sector. The proportion of complaints upheld in the customer’s favour slipped from 57.9 per cent to 55.5 per cent, while the total bill for redress fell to £236.2m, down sharply from £283.7m in the first half of 2025. The average payout also tracked lower, dropping to £215 from £238.
The findings come at a sensitive moment for the high street, with both Lloyds and Santander under fire from consumer groups for the pace at which they are pruning their branch estates. Analysis by Lightyear shows the Spanish-owned lender has shuttered close to 500 sites over the past two years and announced a further 44 closures in January, fuelling accusations that vulnerable customers are being left stranded.
Lurking behind the headline numbers is the motor finance mis-selling scandal, which continues to cast a long shadow over Britain’s lenders. Lloyds has set aside £2bn to cover potential redress linked to so-called secret commission arrangements between car dealers and banks, while Santander has earmarked £461m. Both are among the most heavily exposed names in the sector.
The FCA’s pause on motor finance complaints, in place since January 2024 after volumes surged on the back of concerns over discretionary commission arrangements, is due to be lifted on 31 May 2026, raising the prospect of a fresh wave of grievances landing on lenders’ desks this summer.
Elsewhere, motor and transport insurance proved the standout pain point of the period, with complaints leaping by more than a third to 340,000. That surge helped drive a 10 per cent jump in overall insurance and protection grievances to 790,329. Current accounts remained the single largest category, although the volume eased to 492,149 from 541,493 in the first half.
For Britain’s biggest banks, the latest data offers little immediate respite. With the motor finance reckoning still to come and branch closures continuing to draw political heat, the pressure on customer service teams looks set to remain firmly elevated through 2026.
