Quick Comparison
| Feature | Fixed Rate | Variable Rate |
|---|
| Monthly payment | Constant (during fix) | Can change |
| Rate type | Locked | Tracks market/lender |
| Budget certainty | High | Low |
| Early repayment | ERCs apply | May have ERCs |
| If rates rise | Protected | Pay more |
| If rates fall | Don’t benefit | Pay less |
| Flexibility | Limited | Usually more |
Types of Mortgages Explained
Fixed-Rate Mortgages
| Feature | Details |
|---|
| How it works | Interest rate locked for set period |
| Typical terms | 2, 3, 5, 10 years |
| Payment | Same every month during fix |
| After fix | Moves to SVR or remortgage |
Example: 5-year fix at 4.5% on £250,000 = £1,389/month for 5 years, regardless of what happens to interest rates.
Variable Rate Types
| Type | How It Works |
|---|
| Tracker | Follows Bank of England base rate (e.g., base rate + 1%) |
| SVR | Lender sets rate, can change anytime |
| Discount | Discount off SVR for set period |
| Capped | Variable but with maximum rate |
Example tracker: Base rate + 0.75% at Bank Rate 4.25% = 5.0% rate. If Bank Rate drops to 3.5%, your rate drops to 4.25%.
Standard Variable Rate (SVR)
This is what you default to after a deal ends:
| Feature | SVR Reality |
|---|
| Typical rate | 7-8% (2024-2026) |
| Compared to deals | 2-4% more expensive |
| Flexibility | Can leave anytime |
| Who uses it | Those who forget to remortgage |
Critical: Never stay on SVR longer than necessary. Always remortgage before your deal ends.
Current Rate Environment (2026)
| Type | Typical Rate |
|---|
| 2-year fixed | 4.5-5.5% |
| 5-year fixed | 4.0-5.0% |
| Tracker (base +0.75%) | ~5.0% |
| SVR | 7-8% |
| Bank of England rate | ~4.25% |
Note: Rates change. Check current rates when making decisions.

Cost Comparison
Scenario: £250,000 Mortgage Over 25 Years
Current rates:
- 5-year fixed: 4.5%
- 2-year tracker: Base rate (4.25%) + 0.75% = 5.0%
If rates stay stable:
| Year | Fixed (4.5%) | Tracker (5.0%) | Difference |
|---|
| Monthly | £1,389 | £1,461 | -£72 (fixed cheaper) |
| 5-year total | £83,340 | £87,660 | -£4,320 (fixed cheaper) |
If rates fall by 1% over 2 years:
| Year | Fixed (4.5%) | Tracker (down to 4.0%) | Difference |
|---|
| Monthly (Year 3-5) | £1,389 | £1,315 | +£74 (tracker cheaper) |
| Potential 5-year savings | — | ~£3,000 | Tracker wins |
If rates rise by 1% over 2 years:
| Year | Fixed (4.5%) | Tracker (up to 6.0%) | Difference |
|---|
| Monthly (Year 3-5) | £1,389 | £1,610 | -£221 (fixed cheaper) |
| Potential 5-year extra cost | — | ~£8,000 | Fixed wins |
Key insight: Fixed protects downside, but limits upside. Variable offers upside potential but exposes you to downside risk.

The honest answer: Most UK borrowers choose fixed for the certainty it provides. Variable rates suit those who can handle the risk and believe rates will fall. In uncertain times, fixed gives peace of mind — that mental benefit often outweighs small potential savings.
Whatever you choose: Never sit on SVR. Always remortgage before your deal ends.
