Introduction
For most people in the UK, buying property requires a mortgage. Whether you’re a first-time buyer, moving home, or purchasing a buy-to-let investment, securing the right mortgage deal can save you tens of thousands of pounds over time.
In 2026, mortgage rates remain sensitive to economic shifts, inflation trends, and Bank of England decisions. This means comparing lenders, understanding product types, and improving your financial profile is more important than ever.
This comprehensive guide explains how UK mortgages work, how to compare deals, and how to increase your approval chances.
Understanding How Mortgages Work
A mortgage is a loan secured against property. You repay it monthly over an agreed term (typically 25–35 years).
Your monthly payment includes:
- Capital repayment (reducing the loan balance)
- Interest (the lender’s charge)
The amount you can borrow depends on:
- Income
- Employment status
- Credit score
- Existing debts
- Deposit size
Most lenders offer 4–4.5x annual income as a borrowing guideline.
Types of UK Mortgages in 2026
1. Fixed-Rate Mortgage
- Interest rate locked for 2, 3, 5, or 10 years
- Predictable monthly payments
- Protection against rate rises
Popular among first-time buyers and families.
2. Variable-Rate Mortgage
- Interest rate fluctuates
- Monthly payments can change
- Riskier but may start lower
3. Tracker Mortgage

4. Buy-to-Let Mortgage

How Much Deposit Do You Need?
Deposit size affects:
- Interest rate

- Monthly repayments
Typical Deposit Ranges:
- 5% (first-time buyer schemes)
- 10% standard minimum

Larger deposits reduce overall borrowing costs.
How to Improve Your Mortgage Approval Chances
1. Check Your Credit Score

- Credit utilisation
- Electoral roll registration
Improving your score before applying increases approval chances.

…can significantly improve affordability assessments.
3. Avoid Major Financial Changes
Before applying:
- Avoid changing jobs

Stability improves lender confidence.
Mortgage Comparison: Why It Matters
Mortgage rates vary between lenders.
When comparing deals, consider:
- Interest rate
- Arrangement fees
- Early repayment charges
- Incentives (cashback, free valuation)
Sometimes a slightly higher rate with lower fees may cost less overall.
Using a whole-of-market mortgage broker can help access competitive deals.
Mortgage Costs Beyond Interest
When buying property, budget for:
- Valuation fees
- Solicitor / conveyancing fees
- Stamp Duty
- Survey costs
- Home insurance
Many buyers underestimate these additional expenses.
First-Time Buyer Support in 2026
Government and lender schemes may include:
- Low deposit options
- Shared ownership
- Family guarantor mortgages
- Deposit contribution incentives (new builds)
First-time buyers should compare all options carefully.
Remortgaging Explained
Homeowners nearing the end of a fixed term often remortgage to:
- Secure better interest rates
- Release equity
- Switch lenders
Failing to remortgage may result in being moved to a higher standard variable rate.
Buy-to-Let Mortgage Strategy
Investors should calculate:
- Rental yield
- Stress-tested affordability
- Cash flow after expenses
- Long-term appreciation potential
Comparing multiple lenders is essential in investment scenarios.
