Understanding Early Repayment Charges

ERCs are fees charged when you pay off more than your allowance during a fixed-rate period. They typically:

• Range from 1-5% of the overpayment amount
• Reduce each year of the fixed term
• Don't apply after the fixed period ends
• Can be substantial on large overpayments

Example ERC Schedule:

Year of Fixed Term	Typical ERC
Year 1	5%
Year 2	4%
Year 3	3%
Year 4	2%
Year 5	1%

When ERCs Don't Apply

ERCs typically don't apply when:

• You're on a tracker or SVR (variable rate)
• Your fixed-rate period has ended
• You're within your annual overpayment allowance
• You're moving home (porting your mortgage)
• You or a co-borrower passes away

Tips for Maximising Overpayments

Track Your Allowance

Keep a record of:

• Your mortgage anniversary date
• Overpayments made during each year
• Remaining allowance

Timing Matters

If you're near your anniversary date with unused allowance:

• Make an overpayment before the year resets
• Unused allowance typically doesn't roll over

Consider Your Options

If you want to overpay more than 10%:

1. Wait until your fixed term ends
2. Remortgage to a lender with higher limits
3. Calculate if paying the ERC still saves money overall
