Mortgage Types UK 2026 — Fixed, Tracker, Offset, Interest-Only Explained

Tracker Mortgages Explained UK — How They Work in 2026

Understand how tracker mortgages follow the Bank of England base rate. Pros, cons, when they're good value, and how they compare to fixed rates.

Mortgage information is general guidance only. Mortgages are regulated by the FCA. YOUR HOME MAY BE REPOSSESSED IF YOU DO NOT KEEP UP REPAYMENTS ON YOUR MORTGAGE. Consult an FCA-regulated mortgage adviser before making decisions.

Tracker mortgages move with interest rates — down when rates fall, up when they rise. Here’s how to decide if one is right for you.
