Switching Mortgage Lenders: How to Avoid “Double Payments”

Switching mortgage lenders can feel stressful—especially if your payment date and completion date fall on the same day. Many homeowners worry about making two mortgage payments in one month, but the reality is different. Here’s how to handle it and avoid confusion.


Why It Looks Like a “Double Payment”

If your old lender takes a payment on the 1st and your new lender also collects their first payment in the same month, it seems like you’re paying twice. But here’s why that’s not the case:

  • Interest Refund: Your old lender should refund the interest for the month you switched.
  • Capital Reduction: Any capital paid to your old lender reduces your mortgage balance before the switch.

If you have enough cash reserves, you’re not worse off financially. Still, confirm payment dates with your adviser and both lenders.


Approach 1: Allow Completion

Let the process run as scheduled. Your new lender may collect their first payment in the same month, but you’ll receive an interest refund from your old lender. This approach is simple and avoids complications.


Approach 2: Change Your Direct Debit

If you have time before month-end (after your latest payment clears), ask your current lender to move your next direct debit to a date after your new mortgage completes—say, the 10th.

Pros:

  • Prevents another payment from being taken by your old lender.

Cons:

  • Your mortgage balance won’t reduce as much before completion, which could lead to a smaller surplus or even a shortfall.

Key Tip

Always communicate with both lenders and your adviser to confirm payment schedules and avoid surprises.
