Overview: Halifax and Santander
Halifax was established as a building society in 1853 and converted to bank status in 1997, later merging with Bank of Scotland to form HBOS before being absorbed into Lloyds Banking Group during the 2008 financial crisis. Today, Halifax operates as the UK's largest mortgage lender by volume, with a market share that reflects decades of competitive pricing and wide distribution through both direct and broker channels. Halifax is a high street bank and part of a shareholder-owned group, though its roots as a building society continue to influence its positioning around home ownership and straightforward lending.
Santander UK is a wholly owned subsidiary of Banco Santander SA, the Spanish banking giant and one of the largest financial institutions in the world by market capitalisation. Santander entered the UK market through the acquisition of Abbey National in 2004 and has since become a significant force in UK mortgage lending. Santander operates a smaller branch network than Halifax but compensates with strong digital and telephone channels and a well-developed broker proposition. The lender has a clear strategic focus on competitive remortgage pricing and flexible criteria, particularly for self-employed borrowers, which has made it a staple recommendation among UK mortgage brokers.
Both lenders offer the standard range of residential remortgage products, compete actively at mid-to-higher LTV bands, and are well represented in the broker market. The key differences lie in their criteria for self-employed borrowers, their loyalty pricing approaches, and their specific rate competitiveness at different LTV bands.
Rate and Fee Comparison
Halifax is competitive across its full remortgage product range and is particularly notable for its pricing at higher LTV levels — typically 75-85% — where it has consistently offered rates that compete with or beat the best available from smaller lenders and building societies. As the largest lender by volume, Halifax benefits from scale and distribution efficiency that allows it to maintain competitive pricing across the board. Halifax offers both arrangement fee products (typically around £999) and fee-free alternatives, and periodically runs cashback promotions on selected products. Its loyalty rates for existing customers are a genuine feature — Halifax product transfer rates for existing customers are frequently competitive with the best open market deals.
Santander has built a reputation for consistent competitiveness, particularly at 75-85% LTV, where it regularly features at or near the top of best-buy comparisons. Its fee structure mirrors the market standard, with fee-paying and fee-free product options available. Santander periodically offers cashback on selected remortgage products, typically in the range of £500 to £1,000. The Spanish parent's focus on growing Santander UK's mortgage book has historically translated into aggressive pricing, and this is reflected in the lender's strong position in broker recommendations.
For borrowers with equity levels placing them in the 75-85% LTV band, both lenders are likely to be near the top of any broker comparison. The deciding factor often comes down to the total cost calculation — rate, arrangement fee, and cashback combined — rather than any single number in isolation. A broker can run this calculation accurately for your specific loan size and chosen fixed period.
