2nd Charge Consent

In simple terms, 2nd charge consent is when the 2nd charge lender needs permission from the 1st charge lender to use a property as security against a loan. 

A 1st charge is usually a mortgage, and the lender of this charge will always be able to recover their costs if you defaulted on your mortgage repayments before anyone else. 

If you decided to take out a 2nd charge loan, the lender would need permission from the 1st charge lender and would be able to recover their costs after the 1st charge.
