Other things you can do

The Mortgage Charter aims to help customers who are struggling to pay their mortgage. In line with the Government Mortgage Charter there are two ways to change your mortgage.

Using the Mortgage Charter

  • You can switch to interest only for 6 months or increase your mortgage term. You can only make one change under the Charter.
  • There’s no fee for doing this.
  • There’s no affordability check or advice provided.
  • We won’t do a credit search, so it won’t show on your credit file.
  • If you’re increasing your term a maximum age limit and term applies. 
  • Buy to Let mortgages are excluded.
  • You can cancel and go back to your original terms within 6 months without an affordability check or a credit search. To cancel your request, please call us 0800 783 9738.
     

Already have Mobile and Online Banking? Log on, choose your mortgage account, then click ‘Manage my mortgage’. Or give us a call  on 0800 917 5630. Lines are open 8am to 6pm Monday to Friday and 9am to 2pm Saturday. 

Without using the Mortgage Charter

  • You can change your method of repayment and mortgage term.
  • There’s currently no fee for doing this.
  • We carry out an affordability check and provide advice.
  • We’ll do a credit search which will show on your credit file.
  • If you change to an interest only mortgage, you’ll need a suitable repayment plan in place to pay off the capital at the end of your term. For example, from a mortgage-related endowment policy or ISA.
  • If you’re changing your method of repayment or term a maximum age limit and term applies. 
  • If you make a change to your mortgage, you may not be able to go back to your original terms in the future. Any changes will be subject to an affordability check and our lending policy at the time. 
  • You’ll need to provide evidence of your income. 
  • We’ll also need specific documents from you. Please see our list of documents you may need for your circumstances.

Useful information

It’s important you have a repayment plan in place to repay your interest only mortgage when it ends. If you don’t have a plan, you can think about these options:

Switch to repayment
Convert part or all of your interest only mortgage to repayment so it pays off the interest and the capital. You can apply to do this in our mobile app or in Online Banking. Simply log on, choose your mortgage account and then ‘Manage my mortgage’.

Make overpayments
Make overpayments on your mortgage to reduce the capital balance. You can do this easily online using Online or Mobile Banking

Sell your home
If you’re planning to sell your home you should put your house on the market 6 months before your mortgage ends. Make sure once you’ve sold your home you’ll have enough money to pay off your mortgage and money left over to buy another home.

What to do if you’re worried about repaying your interest only mortgage when it ends
If you can’t afford to pay back the mortgage balance outstanding at the end of your mortgage term, you may have to sell your property or face repossession.

Later life mortgages
We’ve partnered with Legal & General to offer you lifetime and retirement interest only mortgages.

Designed for customers aged 55 or over, a later life mortgage lets you borrow money based on the value of your home, as a loan secured against it, while you continue to live there. The loan is usually repaid when the last surviving borrower dies or moves out of the home into long-term care.

  • With a lifetime mortgage you are able to decide whether you’d like to pay all, some or none of the interest each month.  
  • With a retirement interest only mortgage you must pay the interest in full each month. As a last resort, your home may be repossessed if you do not keep up with your payments.


There’s lots to consider so it’s important to receive financial advice to help you make the right decision. There may be cheaper ways to borrow money. Legal & General has its own team of specialist later life mortgage advisers, to help you find the right option for you. If you speak to one of their advisers, there’s no obligation to proceed.

The Bank of England base rate is the official interest rate set by the Bank of England’s Monetary Policy Committee. Banks and building societies use the base rate to work out interest rates for some mortgage products.
What is the Bank of England base rate?
It’s currently 4.50%.
What is the Follow-on Rate (FoR)?
It’s currently 7.75% (Bank of England base rate plus 3.25%).
What is the Standard Variable Rate (SVR)?
It’s currently 6.75%.
About our different types of mortgage

Follow-on Rate (FoR)FoR is currently 7.75% (Bank of England base rate plus 3.25%).
If you applied for a mortgage deal between 23 January 2018 and 20 November 2023, it transfers to the FoR when the product period ends. For example, you applied for a 2 year fixed rate in April 2023. Your mortgage will transfer to the FoR when the fixed rate ends in 2025.​
It’s a variable rate that tracks the Bank of England base rate. So, it will always move in line with changes to the base rate. This means the rate and your monthly payment will go up or down as the base rate changes.​  

Find out more about our Follow-on Rate 
Standard Variable Rate (SVR)
 
SVR is currently 6.75%.
If you applied for a mortgage deal before 23 January 2018 or from 21 November 2023, it transfers to the SVR when the product period ends. ​
It’s a variable rate that we can change. This means the rate and your monthly payment could go up or down. It doesn’t track the Bank of England base rate, but it may change if the base rate changes. Our mortgage terms and conditions explain what other factors can also influence when we change this rate. We sent you copy of these with your latest mortgage offer.​  

Find out more about our Standard Variable Rate
Tracker rate mortgageThe interest rate tracks the Bank of England base rate for a set period of time. Your monthly payment will go up or down in line with changes to the base rate. So, you need to be sure you could afford it if your interest rate goes up.
Lifetime Tracker and Flexible Offset mortgages are guaranteed to track the base rate for the life of the mortgage.
Fixed rate mortgageThe interest rate stays the same for a number of years, such as 2, 5 or longer. Your monthly payment doesn't change, so you know what you need to pay each month.
If the Bank of England base rate goes up during the fixed rate period, it doesn't affect your monthly payment. If the base rate goes down though, you won't benefit from a lower monthly payment.

This is a brief summary of the 3 different types of mortgages we offer

Fixed rateTracker rateLifetime Tracker

Best for:
For people who want to know how much they need to repay for the next few years
 

 

You can fix your deal for 2, 3 or 5 years. During this fixed period your monthly payments will stay the same. After your fixed period you’ll move onto the Santander Standard Variable Rate. If you want to finish your deal early, you may have to pay an early repayment charge.

Best for:
For people who think interest rates might change in the next few years or want to make unlimited overpayments.

 

 

You can choose a mortgage with an initial rate period and during this period your rate tracks above the Bank of England base rate. With this type of mortgage your payments may vary. The initial rate period is usually 2 years and after that you move onto the Santander Standard Variable Rate.

Best for:
For those who don’t want to look for a new mortgage deal again or who want to make unlimited overpayments. 

 

 

With a Lifetime Tracker mortgage your rate will track above the Bank of England base rate for the life of your mortgage term. Your payments may vary with this type of mortgage.

Repayment mortgage
Your monthly payment covers both the amount you’ve borrowed and interest. So as long as you keep up your payments, your mortgage will be paid off at the end.
Interest only mortgage
Your monthly payment only pays off the interest. You’ll still need to repay the amount you borrowed at the end of your mortgage and will need a separate plan in place to do this (such as an investment or endowment). We may limit the amount allowed on interest only.
Combination
You can choose to pay part of your mortgage as repayment and the other part as interest only.
