What 'charge' even means — and why it matters at renewal
When you get a mortgage, the lender registers a legal claim ('charge') against your home so they can recover the loan if you default. How they register it is where standard and collateral differ — and it's almost invisible until your term ends.
A standard charge is registered for your exact mortgage amount and is specific to that mortgage. When your term is up, a new lender can take it over with a simple, usually free, transfer/assignment. A collateral charge is a re-advanceable registration, frequently for more than you actually borrow — sometimes up to 100–125% of the home's value — which lets the lender advance you more money later without re-registering. The catch surfaces at renewal: many lenders won't accept a collateral charge as a straight transfer, so leaving can mean discharging and registering a brand-new mortgage, with legal fees attached.
