What Is a Second Charge Mortgage and When to Consider One?

If you’re a homeowner looking to raise money without changing your existing mortgage, a second charge mortgage could be worth considering. It’s a flexible option that allows you to unlock the value in your home while keeping your current deal in place.

What Is a Second Charge Mortgage?

A second charge mortgage — sometimes called a secured loan — is a loan that’s secured against your property, just like your main mortgage. The difference is that it’s taken out in addition to your existing mortgage, not instead of it.

This means you’ll end up with two separate mortgages on the same property:

  • Your first charge mortgage (your main one with your original lender)
  • Your second charge mortgage (a new loan from a different or the same lender)

The second lender has a legal claim to your property, but only after the first lender, which is why it’s called a “second charge.”

When Might You Consider a Second Charge Mortgage

A second charge mortgage can be a useful alternative in a few common situations:

  • You're on a great mortgage rate: If remortgaging would mean losing a low fixed or tracker rate, a second charge could let you borrow extra without disturbing that deal.
  • You have early repayment charges (ERCs): Rather than paying hefty fees to exit your current mortgage early, a second charge can provide additional funds while leaving your main mortgage untouched.
  • You need to borrow for specific reasons: Home improvements, consolidating debts, or helping a family member onto the property ladder are typical uses.
  • You've become self-employed or your circumstances have changed: If your income situation has shifted since your original mortgage, or perhaps your credit file has taken a negative impact, a second charge lender may assess affordability differently and be more flexible.

Second Charge vs. Remortgage

While both options allow you to release equity, they work differently:

RemortgageSecond Charge Mortgage
Replaces your existing mortgage with a new oneAdds a new, separate loan alongside your current mortgage
May require paying off your current deal (and any ERCs)Keeps your current mortgage and rate untouched
Can offer lower overall rates if remortgaging makes senseCan be quicker and more flexible, especially for complex income or credit situations

Your advisor can help weigh up which is more suitable based on your personal goals, timing, and overall costs.
