Repayment vs. Interest-Only
Before choosing an interest rate type, you must decide how the capital (the amount you borrowed) will be paid back. This is the most critical decision in your mortgage journey.
Capital Repayment Mortgage
The standard choice for most UK homebuyers
How It Works
Your monthly payment covers both the interest charged by the lender and a portion of the original loan amount (the capital).
The Outcome
Provided all payments are made, the mortgage is completely paid off at the end of the term, and you own the property outright.
Interest-Only Mortgage
Lower monthly payments, but higher long-term risk
How It Works
Your monthly payment covers only the interest on the loan. The original capital amount remains unchanged throughout the term.
The Outcome
At the end of the term, you still owe the full original loan amount. You must have a separate, verified “repayment vehicle” (e.g., property sale, investment) to clear the debt.
Choosing Your Rate Type
Once you know how you’ll repay the capital, you must choose how your interest rate behaves. This dictates your monthly payment stability.
Fixed-Rate Mortgage
Your interest rate is locked for a set period (typically 2, 3, 5, or 10 years). Your monthly payment remains exactly the same, regardless of Bank of England Base Rate changes.
Best for: Budgeting certainty and peace of mind.
Tracker Mortgage
Your interest rate is tied directly to the Bank of England Base Rate (e.g., Base Rate + 1.5%). If the Base Rate goes up or down, your mortgage rate and monthly payment change immediately.
Best for: Borrowers who want to benefit from potential rate cuts and can absorb payment increases.
Discount Variable Mortgage
Offers a percentage discount off the lender’s Standard Variable Rate (SVR) for a set period. Unlike a tracker, it does not automatically follow the Bank of England rate; it only changes if the lender changes their SVR.
Best for: Those seeking slightly lower initial payments than the SVR, but with less predictability than a fixed rate.
Offset Mortgage
Links your savings and current accounts to your mortgage balance. You are only charged interest on the net difference. Your savings remain accessible, but you pay less interest overall.
Best for: Higher-rate taxpayers and those with significant, accessible cash reserves.

A side-by-side look at how the most common UK mortgage structures behave in different economic conditions.
| Mortgage Type | Interest Rate Behavior | Payment Predictability | Best Suited For |
|---|---|---|---|
| Fixed-Rate | Locked for 2–10 years | High (Payments stay the same) | Budget-conscious homeowners, first-time buyers |
| Tracker | Follows Bank of England Base Rate | Low (Payments fluctuate monthly) | Borrowers expecting interest rates to fall |
| Discount Variable | Discount off lender’s SVR | Medium (Changes only if SVR changes) | Those wanting a rate below SVR without a fixed term |
| Offset | Variable, but calculated on net balance | Medium (Depends on savings balance) | Higher earners with substantial accessible savings |
| Interest-Only | Can be Fixed, Tracker, or Variable | Depends on rate type chosen | Experienced investors with verified capital repayment plans |
Mortgage Types FAQ
Answers to the most frequently asked questions about choosing the right mortgage structure in the UK.
The most common mortgage type in the UK is the capital repayment mortgage with a fixed interest rate, typically locked in for 2, 3, or 5 years. This provides borrowers with predictable monthly payments and a clear path to owning their home outright.
A tracker mortgage tracks the Bank of England Base Rate at a set percentage above it, meaning your rate moves immediately when the Base Rate changes. A discount mortgage offers a percentage discount off the lender’s Standard Variable Rate (SVR) for a set period, so it only changes if the lender decides to change their SVR.
An interest-only mortgage can be suitable for experienced investors or those with a solid, guaranteed repayment strategy (like an endowment policy or property sale). However, it carries higher risk because the capital is not being reduced, and it is rarely recommended for standard residential homebuyers without a robust repayment plan.
An offset mortgage links your savings and current accounts to your mortgage balance. You are only charged interest on the difference between the two. For example, if you have a £200,000 mortgage and £20,000 in savings, you only pay interest on £180,000. This reduces your monthly payments or shortens the mortgage term, while your savings remain accessible.
