Questions we get asked

When should I start looking at a remortgage?
Around six months before your current fixed period ends. That is the point at which most lenders will let you reserve a new rate, and it gives you time to react if the valuation or your circumstances have changed.
Does the product fee always make a remortgage worse value?
Not necessarily. A fee-paying product with a lower rate often wins on a large London balance and loses on a small one. The break-even figure here shows how many months of saving it takes to repay the fee.
What happens if I do nothing when my fix ends?
You roll onto the lender's standard variable rate, which is normally several percentage points above the average fixed rate. On a London-sized balance that difference is usually four figures a month.
Is the rate shown here a deal I can apply for?
No. It is the Bank of England's published average quoted rate, shown as reference data so you have a sensible starting assumption. We do not sell or recommend mortgages.
