Is It Worth Paying the ERC to Remortgage?

Frequently Asked Questions

What is an early repayment charge (ERC)?

An ERC is a fee charged by your lender for paying off your mortgage (or overpaying) before the end of your current deal. It is typically a percentage of the outstanding balance, reducing each year.

When should I pay an ERC to remortgage?

If the interest saving over the remaining deal period exceeds the total cost (ERC plus fees), it may be worth switching. This calculator shows the break-even point.

What are typical ERC percentages?

Common ERC structures: 5% in year 1, 4% in year 2, 3% in year 3, 2% in year 4, 1% in year 5. Some lenders use flat rates. Always check your mortgage offer document.

Does the ERC apply to overpayments?

Most mortgages allow overpayments of up to 10% of the outstanding balance per year without an ERC. Check your mortgage terms — overpaying beyond this limit can trigger charges.

Can I port my mortgage instead?

If you're moving house, 'porting' your existing mortgage to the new property avoids the ERC. Not all mortgages are portable, and the new property must meet the lender's criteria.

What happens at the end of my mortgage deal?

Your mortgage reverts to the lender's Standard Variable Rate (SVR), which is typically 1-3% higher than competitive rates. Remortgaging before reversion avoids this.

How far in advance can I lock in a new deal?

Most lenders allow you to secure a new deal 3-6 months before your current deal ends. Some offer 6+ months. Locking in early protects against rate rises.

Are there ERCs on tracker mortgages?

Most tracker mortgages have no ERC (they track the base rate and can be exited at any time). Some have them for an initial period — always check your mortgage offer.

What costs should I include when calculating remortgage savings?

ERC, arrangement/product fees for the new deal, valuation fees, legal/conveyancing costs (sometimes free for remortgages), and any broker fees.

Can I add the ERC to my new mortgage?

Some lenders allow this, but it increases your debt and interest costs. It's generally better to pay the ERC from savings if you can.

What is the average arrangement fee for a new mortgage deal?

Typical arrangement fees range from £0 to £2,000+. Fee-free deals often have slightly higher interest rates — calculate total cost (interest + fees) to compare properly.

How long does a remortgage take?

A straightforward remortgage usually takes 4-8 weeks. Using a mortgage broker and getting all documents ready early can speed this up significantly.
