Choosing between a fixed rate and variable rate mortgage is one of the most important decisions you will make. Each has its own advantages and risks. Here is how they compare with real numbers and examples.
The Four Main Mortgage Types
1. Fixed Rate Mortgage
Your interest rate stays exactly the same for the entire fixed period (usually 2, 3, or 5 years, sometimes 10). Your monthly payment never changes.
How it works: If your rate is 4.5% fixed for 5 years, it stays at 4.5% regardless of what the Bank of England or Federal Reserve does with interest rates.
| Pros | Cons |
|---|---|
| Predictable monthly payments | Usually higher than initial variable rates |
| Easy to budget around | You may pay more if rates fall |
| Protection against rate rises | Early repayment charges if you want to leave |
| Peace of mind | Tied in for the fixed period |
Real examples (2026):
- Halifax: 2-year fixed at 4.7% (75% LTV)
- Nationwide: 5-year fixed at 4.3% (75% LTV)
- HSBC: 3-year fixed at 4.5% (75% LTV)
2. Variable Rate Mortgage (SVR)
Your rate can change at any time, set by the lender. It usually moves when the central bank changes its base rate, but the lender has full discretion.
How it works: If the Bank of England base rate goes up by 0.25%, your lender may increase your rate by the same amount — or more, or less.
| Pros | Cons |
|---|---|
| No lock-in period | Payments can go up suddenly |
| Often lower initial rate | Harder to budget |
| Freedom to overpay without penalty | Lender can increase rate at any time |
| No early repayment charges | Rate changes are unpredictable |
Real examples (2026):
- Nationwide SVR: 6.49%
- Halifax SVR: 6.99%
- HSBC SVR: 6.75%
These rates are typically much higher than fixed or tracker deals, which is why most people remortgage before their fixed period ends.
3. Tracker Rate Mortgage
Your rate tracks (follows) a benchmark rate, usually the Bank of England base rate, plus a set margin.
How it works: If the base rate is 4.25% and your tracker rate is “base rate + 0.99%”, your rate is 5.24%. When the base rate changes, your rate changes automatically.
| Pros | Cons |
|---|---|
| Transparent — you know what you are paying | Payments rise when base rate rises |
| Usually lower than fixed rates | No payment certainty |
| Often lower arrangement fees | Can increase significantly |
| May have no or lower ERCs | Less budgeting certainty |
Real examples (2026):
- HSBC Tracker: Base rate + 0.99% = 5.24% (2-year tracker, 75% LTV)
- Nationwide Tracker: Base rate + 1.09% = 5.34% (2-year tracker)
- Barclays Tracker: Base rate + 1.14% = 5.39% (2-year tracker)
4. Discount Rate Mortgage
Your rate is a discount off the lender’s Standard Variable Rate (SVR). The discount stays the same percentage, but the actual rate changes as the SVR changes.
How it works: If the lender’s SVR is 6.5% and you get a 1.5% discount, your rate is 5.0%. If the SVR rises to 7.0%, your rate becomes 5.5%.
| Pros | Cons |
|---|---|
| Lower rate than SVR | Still rises when SVR rises |
| Lower fees often | Less transparent than trackers |
| Flexible | SVR changes are at lender’s discretion |
| May have no ERCs | Limited term options |
Real examples (2026):
- Santander: 2-year discount at 5.1% (SVR minus 1.4%, 75% LTV)
- Barclays: 2-year discount at 5.0% (SVR minus 1.5%)
Side-by-Side Comparison
| Feature | Fixed | Variable (SVR) | Tracker | Discount |
|---|---|---|---|---|
| Rate changes | No (during fixed period) | Yes, anytime | Yes, with base rate | Yes, with SVR |
| Payment predictability | High | Low | Medium | Medium |
| Initial rate | Higher | Highest | Lower | Medium |
| Early repayment charges | Yes (usually) | Usually no | Sometimes | Sometimes |
| Lock-in period | 2-10 years | None | None | None |
| Best for | Certainty seekers | Flexibility seekers | Rate-drop bettors | Budget-conscious |
Current Rate Environment (2026)
As of mid-2026, here is where rates stand:
| Rate Type | Typical Range (75% LTV) |
|---|---|
| 2-year fixed | 4.5-5.0% |
| 5-year fixed | 4.2-4.8% |
| Tracker | 5.0-5.5% |
| Discount | 5.0-5.5% |
| SVR | 6.5-7.0% |
Key insight: Fixed rates are currently slightly lower than tracker rates, which is unusual. This happens when the market expects rates to stay flat or fall — lenders price fixed rates based on future expectations.
When to Choose Each Type
Choose Fixed Rate If:
- You want certainty and hate surprises
- You are on a tight budget and cannot afford payment increases
- You think rates will rise in the coming years
- You are a first-time buyer and want stable payments while you settle in
- You plan to stay in the property for the full fixed period
Example: A first-time buyer earning £35,000 takes a 5-year fixed at 4.3% because they need to know exactly what they will pay each month while building their career.
Choose Tracker Rate If:
- You think rates will fall or stay flat
- You want a lower initial rate
- You can afford to pay more if rates rise
- You want more flexibility to overpay or remortgage
- You do not want to be locked in
Example: A homeowner with a high income takes a 2-year tracker because they believe the Bank of England will cut rates within 18 months, and they can absorb a payment increase if they are wrong.
Choose Variable (SVR) If:
- You are between fixed deals and waiting for the right moment
- You need maximum flexibility (e.g., planning to sell soon)
- You are overpaying significantly and want no ERCs
- You have a small mortgage and the rate difference does not matter much
Example: A retiree with a £50,000 mortgage pays SVR because the amount is small, they want no lock-in, and they might pay it off completely from savings.
Choose Discount Rate If:
- You want a lower rate than SVR but still want flexibility
- You do not want to be locked in to a fixed deal
- You think the lender will not raise SVR aggressively
- You are comfortable with some rate variability
Example: A self-employed worker with irregular income takes a 2-year discount because they want lower monthly payments and the flexibility to overpay when they have a good month.
How to Decide: A Simple Framework
Ask yourself these five questions:
- Can I afford a 2% rate increase? If no, go fixed.
- Do I plan to stay more than 3 years? If yes, a longer fixed period may save money.
- Do I want to overpay significantly? If yes, consider tracker or variable with no ERCs.
- Do I think rates will fall? If yes, tracker or variable lets you benefit.
- Do I sleep better knowing my payment is the same? If yes, go fixed.
Common Mistakes to Avoid
- Choosing SVR without thinking. This is usually the most expensive option. Only stay on SVR if you have a specific reason.
- Fixing for too long. A 10-year fixed gives certainty but ties you in for a decade. Most people fix for 2-5 years.
- Ignoring fees. A lower rate with high fees may cost more than a slightly higher rate with no fees.
- Not remortgaging when the fixed period ends. If you do nothing, you move to SVR and pay hundreds more per month.
- Trying to time the market. Nobody knows exactly where rates will go. Choose based on your own circumstances, not predictions.
Summary
There is no single “best” mortgage type. The right choice depends on your income, risk tolerance, how long you plan to stay, and what you think interest rates will do. For most first-time buyers and anyone on a tight budget, a fixed rate mortgage offers the peace of mind you need. For those who want flexibility or believe rates will fall, a tracker or discount rate can save money. Whatever you choose, make sure you remortgage before your deal ends — otherwise you will end up on an expensive SVR that nobody should be paying.
