Quick Answer: Remortgage vs Further Advance in 2026
Take a further advance when you're mid-deal on a good rate and don't want to disturb it (or trigger early repayment charges) — you keep your existing mortgage and add a separate borrowing at your current lender's further-advance rate. Remortgage when your deal is ending, or when a new lender's rate on the whole (larger) balance beats keeping your current deal plus a further advance. A secured loan is a third option. Compare all three on true cost; a broker can model them.

How Each Route Works
The two routes differ in what they touch:
- Further advance — additional borrowing from your current lender, on top of (and separate from) your existing mortgage. Your main deal stays untouched (no ERCs), and the extra is on a separate rate, often for the remaining term or a new deal period.
- Remortgage — you move your whole balance (existing plus the new borrowing) to a new lender, on a single new deal. This may give a better rate on everything, but redeems your current deal (possibly triggering ERCs if mid-term).
- The key variable — whether your current main rate is cheap. If it is, keeping it (via a further advance) and adding the extra separately often beats remortgaging the lot at today's rates.
