Why choose first direct for your mortgage?

The perfect mortgage looks different to everyone, that's why we offer a range of mortgage types and rates. Whichever first direct mortgage you choose, we could help you feel right at home:

  • mortgage advisers available 7 days a week
  • you could get an agreement in principle that lasts 6 months, sorted in a 30-minute phone call
  • fee-free valuation (Fee Saver mortgages available, too)
  • mortgage terms up to 40 years
  • if you already have a mortgage with us, you can take your first direct mortgage with you when you move house (known as porting)
  • view your mortgage balance on the first direct App
  • make unlimited overpayments on a first direct mortgage.
