Santander vs HSBC Remortgage

Overview: Santander and HSBC as Remortgage Lenders

Santander: Santander is a well-established mainstream lender with a broad product range and significant remortgage volume. It is known for being competitive on rates across multiple LTV bands and has a reasonable track record of flexibility on certain criteria, including one-year self-employment accounts in qualifying cases. Santander also offers cashback on selected remortgage products. It has an extensive branch network and a dedicated telephone mortgage team, as well as a solid digital application process for remortgage cases.

HSBC: HSBC is a global bank with a strong UK mortgage presence. It is particularly well known for pricing competitively at lower LTV bands — for borrowers with 40% or more equity, HSBC frequently features among the best rates available in the entire market. HSBC does not operate a traditional broker network in the same way as many other lenders and historically handled a higher proportion of direct applications, though it has expanded its broker distribution in recent years. HSBC also has a Premier mortgage service for higher-net-worth customers, and HSBC Private Bank for very large loans.

Both lenders are authorised and regulated by the FCA and PRA and are covered by FSCS protection up to £85,000. Both offer free standard valuations on remortgage applications. HSBC and Santander both provide free standard legal services on most remortgage products through their respective solicitor panels.

Rates and Fees: Santander vs HSBC

HSBC has a reputation for pricing aggressively at lower LTV bands. For borrowers with 40% or more equity (60% LTV or below), HSBC is frequently among the most competitive lenders in the market. Its willingness to price keenly at this level reflects both its access to low-cost funding and its strategy of attracting high-quality, low-risk mortgage customers. For borrowers at 60% LTV who can meet HSBC's criteria, it is almost always worth including in any comparison.

At higher LTV bands — 75% to 85% — the competitive landscape shifts. HSBC is still competitive but may not always lead the market, and Santander often matches or beats it in the 75% to 85% range. At 90% LTV, both lenders compete but neither consistently dominates, and the comparison with Halifax, Nationwide, and Barclays becomes equally important.

In terms of fee structures, both lenders offer fee-free and fee-bearing products. HSBC's arrangement fees on remortgage products are broadly in line with market norms. Santander similarly offers both options, with cashback available on some products as an alternative incentive to a fee reduction. The best value option between fee and fee-free products depends on the outstanding loan size — larger loans generally favour fee-bearing products.

Who Suits Santander vs HSBC for a Remortgage

HSBC may be the better choice if:

• Your LTV is 60% or below — HSBC is consistently among the most competitive lenders at low LTV ratios.
• You are an existing HSBC Premier or Advance customer — HSBC sometimes provides advantages for customers with existing current account or savings relationships.
• Your income is straightforward (employed, PAYE, consistent salary) and you want a large, globally recognised bank.
• You are comfortable with a primarily digital and telephone application process rather than wanting extensive branch support.
• You want a large loan — HSBC has higher maximum loan limits than some mainstream competitors and has private banking options for significant loan sizes.

Santander may be the better choice if:

• Your LTV is between 75% and 85% — Santander is often competitive in this band and may match or beat HSBC.
• You are self-employed and have at least one full year of accounts — Santander has shown flexibility in this area in certain qualifying cases.
• You want cashback alongside a competitive rate on your remortgage.
• You prefer a lender with a branch network where face-to-face support is available as a backup option.
• Your circumstances are slightly non-standard in other ways — Santander's underwriting has historically been reasonably pragmatic for near-mainstream cases.

Application Process and Customer Experience

HSBC has invested significantly in its digital mortgage application process in recent years. Its online portal allows applicants and brokers to submit applications, upload documents, and track progress digitally. HSBC's remortgage processing team handles a high volume of applications and is generally rated well for speed at standard cases. Where HSBC can sometimes be slower is in cases requiring manual underwriting or where additional documentation is needed, as its processes are highly standardised.

Santander's remortgage application process is also largely digital, with a dedicated telephone team available for queries. Santander has a good reputation in the intermediary market for reasonable turnaround times and accessible underwriting teams when queries arise. Its branch network — while not used for the majority of mortgage applications — provides an additional touchpoint that some customers find reassuring.

One practical difference between the two lenders is HSBC's approach to broker distribution. While HSBC has expanded its broker panel significantly, some smaller or less-established brokers may not have direct access to HSBC products. Santander has a broader broker panel and has historically been more accessible through intermediaries. This is largely a behind-the-scenes consideration for most borrowers, but it is worth being aware of when choosing a broker to handle your remortgage.
