When not to remortgage

2 min read
Oct '25 • by Amy Bulger

Quick summary

You should avoid remortgaging if you are in negative equity, meaning you owe more than your property is worth, or if your income has dropped recently, making lenders cautious. Also, stay clear if you're already on a low rate or face hefty early repayment charges, unless a product transfer or expert advice suggests otherwise.

Knowing when the right time to remortgage can sometimes be tricky. You might have heard your friends talking about how they remortgaged the house and added a huge two-story extension, giving them the room they needed for their young family. However, it's important to remember that everyone's circumstances are different and just because that worked for your friend, doesn't mean that it could be the right thing for you too.

There are lots of times when we'd advise against remortgaging...

Little equity

If you owe your lender more than the property is worth, then you’re in what they call ‘negative equity’. It can be difficult to remortgage your house when you’re in negative equity - unless you have separate funds to repay the difference.

However, don’t just assume this is impossible. Everyone’s circumstances are different, just like every lender’s criteria is different, so it’s always worth speaking with a mortgage adviser to consider all your options.
