Quick Answer: Best Debt-Consolidation Remortgage in 2026
Most mainstream lenders — Halifax, Nationwide, Santander, NatWest and others — allow remortgaging to consolidate debt, typically up to 80-85% LTV, sometimes lower for large consolidation. You move expensive debt (cards at 20-30%, loans at 8-15%) onto your mortgage rate (around 4.5-5.5%), cutting monthly payments sharply. The trade-off: spreading debt over 20-25 years can cost more interest overall, and you secure it against your home. Best assessed with a broker who can model the true lifetime cost.
How Debt-Consolidation Remortgaging Works
You increase your mortgage to pay off other debts:
- The mechanics — you borrow more against your home (raising your loan and LTV), and the extra cash clears your cards and loans. You're left with one larger monthly mortgage payment instead of several.
- The monthly saving — because mortgage rates are far below card/loan rates, your total monthly outgoings usually fall significantly, easing cash-flow pressure.
- The lifetime cost — spreading, say, a £15,000 debt over 25 years at a mortgage rate can cost more in total interest than clearing it over 3-5 years, even at a higher rate. Always compare total cost, not just monthly payment.
- LTV limits — lenders cap how much you can raise for consolidation, often 80-85% LTV, with stricter limits for very large consolidation relative to income.
