Step 3: Full application and documents (week -8 to -6)
Submit your full application via santander.co.uk (direct), through a broker, or in branch (Santander is one of the few majors still offering meaningful branch mortgage support). The application takes 60–90 minutes and requires:
**Identity and address**:
- Valid UK passport or UK driving licence
- Utility bill, council tax bill, or bank statement within 3 months
- If non-UK national: visa documentation, residency permit
**Employment (employed)**:
- Last 3 months' payslips
- Last 3 months' bank statements showing salary credits
- Most recent P60
- P11D if bonus or company car applies
**Employment (self-employed)**:
- Last 2 years of SA302s (Self Assessment tax calculations) from HMRC
- Last 2 years of tax year overviews
- Last 3 months' business bank statements
- If limited company director: 2 years of Ltd company accounts, salary + dividend evidence
**Mortgage and property**:
- Current mortgage statement within last 3 months
- Building insurance certificate (can be arranged post-application)
**After submission**: Santander acknowledges within 24-48 hours. Underwriting typically takes 2-3 weeks for straightforward cases. Santander is known for being thorough (sometimes slower than Halifax or first direct) but reliable — declines are rare once application is accepted.
**Valuation**: AVM for most cases up to £1m at 85% LTV. Physical valuation costs £310-£995 if needed (higher than some competitors).
Step 4: Offer, legal work and completion (week -6 to 0)
When Santander issues the mortgage offer, your solicitor takes over. Timeline:
**Weeks -6 to -4**: Offer issued (lasts 3-6 months). Solicitor contacts existing lender for redemption figure. Santander's redemption statements historically took up to 10 days — factor in this delay if you're remortgaging away from Santander.
**Weeks -4 to -2**: Legal searches (local authority, environmental, water/drainage) typically 10-15 working days. Santander's panel solicitor (LMS Legal Marketing Services) handles most remortgages efficiently.
**Weeks -2 to -1**: Final signatures, mortgage deed, completion statement prepared.
**Week 0 (completion day)**: Drawdown. Santander pays existing lender, your new Santander mortgage is active, direct debit starts next month.
**Total timeline**: 5-7 weeks typical, 7-9 weeks for complex cases. Santander is typically middle-of-pack on completion speed — faster than Nationwide, slower than Halifax or first direct.
**Post-completion**: manage the mortgage through santander.co.uk online banking or the Santander app. First direct debit date is visible in the 'Mortgages' section. Your old lender sends a closing statement within 30 days showing the balance redeemed.
Santander-specific tips for a smooth remortgage
**Use the Santander app from day one.** The app shows application status, document requests, and completion timeline. You can upload documents directly and message the processing team.
**Choose Santander's free legal service for vanilla cases.** It's LMS-managed, reliable, and saves £400-£600 vs using your own conveyancer. For complex titles or transfer-of-equity cases, use your own solicitor.
**Book a Santander mortgage advisor appointment if you're unsure.** Santander is one of the few major lenders still offering in-branch or phone advisor sessions. Useful for first-time remortgage customers or those with mixed income streams.
**123 World customers: check promotional offers.** Santander frequently runs 123 World-exclusive mortgage completion cashback (£250-£500 typical). These aren't always advertised widely.
**Non-UK nationals: Santander is relatively friendly.** Compared to some other high-street banks, Santander has structured processes for Tier 2 and skilled worker visa applicants. Minimum UK residency is typically 2 years, but exceptions exist for high-earning professionals.
**Don't leave application to the last 6 weeks.** Santander's slower underwriting process means last-minute remortgages can result in completion just after your current deal ends — forcing you onto SVR. Apply 10-12 weeks before your current deal ends for safety.
**Branch support is genuinely useful for complex cases.** Self-employed with mixed income, buying out a partner, adding a new applicant — these are often handled better in a branch appointment than DIY online. Santander still has 400+ UK branches.
**Check the tracker option seriously.** Santander's tracker at Base +0.90% with no ERC is flexible — if you're expecting Bank of England cuts, the tracker captures them. Combined with Santander's solid day-to-day service, it's a genuine alternative to locking in a fixed rate in an uncertain environment.
Important: Your home may be repossessed if you do not keep up repayments on your mortgage. There will be a fee for mortgage advice. The actual rate available will depend on your circumstances. Think carefully before securing other debts against your home.
