When to remortgage

Start looking about six months before your deal ends. Most lenders let you lock in a new rate up to six months early. If you do nothing, you move to the standard variable rate (SVR), which is often much higher.

Fees to include

  • Arrangement or product fee, often £0 to £1,999.
  • Valuation and legal fees. Many remortgage deals include these free.
  • Early repayment charges if you leave your current deal early.
  • Broker fee, if your broker charges one.

Product transfer or full remortgage?

A product transfer is a new deal with your current lender. It is quick and often has no credit check or legal work. A full remortgage to a new lender can get a better rate, and lets you borrow more.

Frequently asked questions

Is a low fee or low rate better?

On bigger loans a lower rate usually wins. On small loans a no-fee deal is often cheaper. The calculator shows the net saving.

Can I remortgage to borrow more?

Yes, subject to affordability and your LTV. This is called capital raising.
