Santander vs Nationwide Remortgage

Overview: Santander and Nationwide as Remortgage Lenders

Santander: Santander entered the UK mortgage market significantly when it acquired Abbey National in 2004 and subsequently took on the mortgage books of Alliance & Leicester and Bradford & Bingley. This history gives it an enormous mortgage portfolio and deep experience in UK remortgage lending. Santander operates across direct and broker channels, offers a comprehensive product range, and has historically been willing to show some flexibility on certain borrower types, including self-employed applicants in some cases.

Nationwide: Nationwide is the UK's largest building society and a major force in the residential mortgage market. As a mutual, it is owned by its members (those with mortgages or savings accounts with Nationwide) rather than external shareholders. Nationwide is well known for its strong brand reputation, customer service ratings, and clear lending criteria. It has a comprehensive new build policy, is active at higher LTV bands, and is regularly competitive on rates. Nationwide also operates Accord Mortgages as its intermediary-only lending arm, which sometimes offers different products to those available directly through Nationwide.

Rates, Fees and Incentives

Both Santander and Nationwide are regularly competitive in remortgage rate tables and both offer products across key LTV bands from 60% to 90%. The specific lender offering the best rate changes regularly depending on market conditions, and it is not possible to say that one consistently beats the other across all products and time periods.

Nationwide offers free standard legal work and free valuations on most remortgage deals. It also sometimes offers cashback on selected products, though this varies by product generation. Nationwide's fee structures are broadly standard, with both fee-bearing and fee-free options available. Its arrangement fees on fee-bearing products are competitive with market norms.

Santander similarly offers free legals and free valuations on standard remortgage applications. It has a track record of offering cashback deals and is known for pricing competitively in the 75% to 85% LTV band. Santander's range of fixed and tracker products is broad, and it is worth comparing specifically at the LTV and product type most relevant to your situation.

One structural advantage Nationwide has is the Accord Mortgages brand, which is exclusively available through brokers. If you are using a broker for your remortgage, it is worth ensuring they compare both the Nationwide direct products and the Accord range, as Accord sometimes offers rates not available through the Nationwide direct channel.

Who Suits Santander vs Nationwide for a Remortgage

Nationwide may be the better choice if:

• You are looking for a lender with a strong customer service reputation and mutual ownership structure.
• You have a new build property — Nationwide has one of the most comprehensive new build policies among mainstream lenders.
• Your LTV is between 80% and 90% — Nationwide is consistently active and competitive at higher LTV bands.
• You are working through a broker — Accord (Nationwide's intermediary arm) often provides additional product options alongside direct Nationwide products.
• You value a lender that invests in customer-facing technology and has a track record of positive customer outcomes.

Santander may be the better choice if:

• You are self-employed with at least one year of accounts and a strong recent income trajectory.
• You are looking for cashback alongside a competitive rate and Santander's current cashback offer is competitive.
• Your LTV is between 75% and 85% and Santander is leading the market at the point you apply.
• You are an existing Santander current account customer, where processing can sometimes be marginally smoother due to existing data already held by the bank.

As with all lender comparisons, the right answer changes based on prevailing market conditions and your specific profile. Rates in particular fluctuate significantly, and the advice to compare both lenders — alongside the full market — through a whole-of-market broker remains the most reliable guidance.

Application Process and Wider Considerations

Both Santander and Nationwide offer digital remortgage applications and provide application trackers. Nationwide's online application portal is well regarded and the lender invests consistently in its digital infrastructure. Its customer service is regularly well rated in independent surveys, and its telephone mortgage team is known for competence and helpfulness.

Santander's mortgage application process is also primarily digital, with telephone support available. Santander has a larger branch network than Nationwide across certain regions, which can be useful for borrowers who prefer face-to-face support at some point in the process, though the majority of the remortgage process is handled digitally or by telephone at both lenders.

One practical consideration is that Nationwide is a building society, which means its borrowing constraints are set by the Building Societies Act — it must keep a minimum proportion of its lending in residential mortgages. This actually reinforces its focus on the residential mortgage market, which is reflected in the quality of its mortgage products and service.

For self-employed borrowers, Santander has historically shown more flexibility than Nationwide on income documentation requirements. Nationwide generally requires two years of accounts and takes a relatively conservative approach to income averaging. Santander's willingness to consider one year of accounts in some cases gives it an advantage for recently self-employed borrowers. For all other borrower types, the comparison is closer and rates and incentives at the point of application become the decisive factors.
