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 |

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.
