Helping you understand if a fixed rate mortgage is right for you

Fixed rate mortgage

Understand fixed rate mortgages and how they could protect you from interest rate rises.

NatWest mortgages are available to over 18s. Your home or property may be repossessed if you do not keep up repayments on your mortgage.

Key summary

  • A fixed rate mortgage gives you a fixed interest rate for a set time.
  • When your fixed rate ends, your mortgage will move onto your lender’s Standard Variable Rate (SVR) unless you choose a new rate.

What is a fixed rate mortgage?

  • A fixed rate mortgage means your repayments have a fixed interest rate for usually 2 or 5 years.
  • That means you'll pay off the same amount every month during that time.

What are our fixed rate mortgage options?

When you take out a fixed rate mortgage, you can generally choose the length of time to fix it for, usually between 2 and 5 years. You'll need to consider how long it might be until you're moving home again, and the potential impact of rising or falling interest rates over time. Here are some examples of fixed rate mortgage options:

2 year fixed rate mortgage

A 2 year fixed rate means your monthly payment will stay the same for 2 years.

After your rate ends, your mortgage will move onto the lender's Standard Variable Rate (SVR). Unless you renew your mortgage and pick a new rate, or remortgage to a new lender.

  • After 2 years, you'll be able to remortgage (move your mortgage to a new lender) or move home without paying an Early Repayment Charge (ERC). 
  • A 2 year fixed mortgage may be a good option if you plan to move home in the next couple of years.

5 year fixed rate mortgage

If you choose a 5 year fixed rate mortgage, your monthly payments will stay the same for 5 years. This means you won’t move onto the lender’s Standard Variable Rate (SVR) until after 5 years.

  • When your fixed rate ends, you can remortgage without paying an Early Repayment Charge (ERC). If you change your mortgage before your rate ends, it's likely you'll need to pay an ERC.
  • If you're staying in your home for a while, a 5 year fixed rate gives you the stability of knowing exactly what your monthly repayments will be. Some people choose this for financial predictability.
  • Locking in an interest rate for 5 years can protect you from potential rate increases. If rates decrease within this period, you could change to a lower rate – but you may need to pay an ERC to exit your current deal early.

What are the benefits of a fixed rate mortgage?

You’ll know exactly how much your mortgage will cost each month.

Your payments won’t increase even when your lender’s SVR goes up. But they may increase at the end of the fixed period.

It’s easier to budget each month when you know what you’re paying.

Please be aware that if your lender's mortgage rates fall, you'll still be tied into your fixed rate mortgage until the introductory rate ends.

You could pay an Early Repayment Charge to exit your current deal and find a new rate.

Is a fixed rate mortgage best for me?

A fixed rate mortgage could be ideal if you want to keep your payments the same every month and protect yourself from rising interest rates.

What happens when my fixed rate mortgage ends?

After your fixed rate ends, your mortgage moves onto the Standard Variable Rate (SVR). Unless you choose to renew your mortgage and pick a new rate.

On the SVR your rate could either rise or fall, depending on changes in the interest rate we charge. Don't worry, we'll contact you before your fixed rate ends.

For more information on the SVR, take a look at our SVR mortgage guide.
