How to read the result

The “monthly difference” shows the gap between your current payment and what you’d pay on the new rate at the same balance and remaining term. A positive number means you’d save each month.

Things to factor in

Product fee (often £499–£1,499) — paying upfront is usually cheaper than adding to the loan.
Early Repayment Charge if you exit your current deal early.
Valuation and legal fees — many remortgage products include free legals.
Whether to switch lender or stay (a product transfer).

Frequently asked questions

When should I start looking at remortgaging? +

About six months before your current fixed deal ends. Most lenders let you secure a new rate that far in advance and switch to it if better rates appear closer to the date.

What is an ERC? +

An Early Repayment Charge applies if you exit your mortgage during the fixed period. It’s usually a percentage of your outstanding balance and tapers down each year.

Can I remortgage with bad credit? +

Often yes, especially with your existing lender (a product transfer) which usually doesn’t require a new affordability or credit assessment.

Should I add the product fee to the loan? +

Adding the fee spreads it over the term but you pay interest on it. Paying upfront is cheaper overall if you have the cash.

What if I do nothing when my deal ends? +

You drop onto your lender’s Standard Variable Rate (SVR), which is typically much higher than fixed-deal rates.
