What is a tracker mortgage?

Learn what a tracker rate mortgage is, how it works, and whether it could be right for you.

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 tracker mortgage is typically linked to the Bank of England (BoE) base rate
  • This means the interest you pay will rise or fall depending on the base rate
  • Tracker mortgages usually last for 2 or 5 years

What is a tracker mortgage?

A tracker mortgage is a type of variable rate mortgage where the interest rate rises and falls in line with another interest rate. They typically follow the Bank of England’s base rate and can last for a term of 2 or 5 years.

If the rate drops, your monthly mortgage payments will also drop. You could take advantage of these lower rates by overpaying on your mortgage. This could make it quicker to pay off your mortgage and lower the amount of interest you pay.

How often can the base rate change?

The Bank of England can change the base rate during Monetary Policy Committee (MPC) meetings, which generally happen every six weeks.

The MPC reviews the base rate to keep inflation stable. Depending on economic conditions, the Bank could choose to increase or lower the interest rate – or keep it the same.

How are mortgage tracker rates set?

Tracker mortgage rates are linked to the Bank of England base rate, or another external rate. Your lender adds a set percentage on top, which determines your mortgage rate.

Trackers usually run for a period of 2 or 5 years, or for the whole life of the mortgage. When your tracker deal ends, your mortgage will move onto the Standard Variable Rate (SVR) unless you choose a new deal.

Tracker mortgages pros and cons

Pros

If the base rate goes down, you pay less interest on your mortgage and monthly repayments.
 

Tracker mortgages offer more flexibility if you want to switch to a new deal – sometimes without any fees. At NatWest, we call this Track and Switch.

Cons

If the base rate goes up, so will your mortgage payments, as you're not protected by a fixed rate.

 

The amount of interest you pay can change suddenly, which could mean unpredictable payments.

How long do tracker mortgage deals last?

Tracker mortgage deals can last for a short or long period depending on your provider:

  • Term tracker: These typically last for a fixed term of 2 or 5 years.  
  • Lifetime tracker: These last for the entire mortgage term, often 25 to 35 years.

Why not try Track and Switch?

Unsure about a tracker or fixed rate mortgage? Track and Switch is a NatWest feature that allows you to take a tracker mortgage now and switch to a fixed rate mortgage later.

You can switch to any fixed mortgage after your mortgage has started. You won't be credit checked or credit scored again.

You may switch tracker products to any NatWest fixed rate product. This is subject to meeting the new product criteria and availability at the time of application and without incurring the Early Repayment Charge.

You'll have to pay any fee(s) applicable to the new product at that time. The new fixed rate product may carry an Early Repayment Charge.

To complete a Track and Switch, log into your Manage My Mortgage portal.
