Interest rates can have a big effect on how much you pay for your mortgage each month, but the impact depends on the type of mortgage you have and where you are in your deal.
For some borrowers, a change in interest rates will not affect repayments straight away. For others, particularly those on tracker or variable rate mortgages, monthly payments can change much sooner.
At Manchester Mortgages, we help homeowners understand how mortgage interest rates may affect their current deal, future repayments and remortgage options.
What Is the Bank of England Base Rate?
The Bank of England base rate is one of the main interest rates used across the UK financial system.
How Does the Base Rate Work?
The base rate influences how much banks and lenders pay to borrow money. This can then affect the mortgage rates offered to customers.
It does not mean every mortgage rate moves by exactly the same amount, but it is an important part of how mortgage pricing works.
Why Does the Bank of England Change Interest Rates?
The Bank of England may raise or lower the base rate to help manage inflation and wider economic conditions.
Higher rates can make borrowing more expensive, while lower rates can reduce borrowing costs in some circumstances.
Base Rate vs Mortgage Rate: What Is the Difference?
The base rate is set by the Bank of England. Your mortgage rate is set by your lender.
Mortgage rates can be influenced by the base rate, funding costs, competition, market expectations and the lender’s own pricing.
How Do Interest Rates Affect Your Mortgage?
The effect depends on your mortgage type.
What Happens When Mortgage Rates Rise?
If you are on a variable mortgage, your monthly repayments may increase.
If you are on a fixed rate, your payments usually stay the same until the fixed period ends.
What Happens When Mortgage Rates Fall?
Some borrowers on tracker or variable deals may benefit from lower payments.
Fixed rate borrowers will usually continue paying the same amount until their existing deal finishes.
Why Mortgage Rates Do Not Always Follow the Base Rate Immediately
Lenders also consider what they expect interest rates to do in the future.
This means mortgage rates may move before a base rate decision, after it, or sometimes by a different amount.
How Interest Rates Affect Different Types of Mortgages
Fixed Rate Mortgages
A fixed rate mortgage keeps your interest rate unchanged for an agreed period.
That gives you predictable monthly repayments, even if the Bank of England base rate changes.
The main issue comes when the fixed period ends and you need to review your next deal.
Tracker Mortgages
Tracker mortgages normally follow an external rate, often the Bank of England base rate, plus a set margin.
If the tracked rate rises, your mortgage rate usually rises too. If it falls, your rate may fall.
Discount Mortgages
A discount mortgage gives you a reduction from the lender’s standard variable rate.
If that standard variable rate changes, your mortgage rate can also change.
Standard Variable Rate Mortgages
A standard variable rate, often called an SVR, is set by the lender.
It can change and may be higher than rates available on other mortgage products.
Interest Only Mortgages
With an interest only mortgage, your monthly payments mainly cover interest rather than reducing the original capital balance.
Changes in the interest rate can therefore have a noticeable effect on monthly costs.
Repayment Mortgages
With a repayment mortgage, your monthly payment covers both interest and part of the capital.
Higher mortgage rates usually increase the monthly amount needed to repay the loan over the agreed term.
How Do Higher Interest Rates Affect Monthly Mortgage Payments?
The higher the mortgage rate, the more interest you normally pay.
Mortgage Repayment Examples at Different Interest Rates
Imagine two borrowers with similar mortgage balances and terms.
The borrower with the higher interest rate will usually have the larger monthly repayment because more of the payment is going towards interest.
The exact difference depends on the loan size, mortgage term and repayment method.
Why Your Mortgage Balance Matters
A rate increase on a larger mortgage balance usually has a greater effect in pounds than the same rate increase on a smaller balance.
This is why two borrowers can experience very different changes even if their mortgage rates move by the same percentage.
How the Mortgage Term Changes Your Repayments
A longer term can reduce the monthly repayment, but it can also mean paying interest for longer.
A shorter term usually means higher monthly payments but can reduce the total interest paid over the life of the mortgage.
What Happens to Your Mortgage When a Fixed Rate Ends?
When a fixed mortgage deal finishes, your options should be reviewed carefully.
Moving Onto Your Lender’s Standard Variable Rate
If you do nothing, you may move onto your lender’s standard variable rate.
This could mean a significant change in your monthly repayment.
Choosing a New Fixed Rate
A new fixed rate can provide certainty over your monthly payments for another agreed period.
Switching to a Tracker Mortgage
A tracker may suit borrowers comfortable with payments changing if the underlying rate moves.
Product Transfer vs Remortgage
A product transfer means switching to another deal with your existing lender.
A remortgage means moving to another lender.
Which option is suitable depends on rates, fees, affordability and your circumstances.
Should You Remortgage When Interest Rates Are High?
There is no single answer.
Review Your Existing Mortgage Deal
Start by checking your current interest rate, when the deal ends and whether any early repayment charges apply.
Compare the Total Cost of a New Mortgage
A lower rate does not automatically mean the cheapest overall deal.
You also need to consider fees and the length of the new product.
Consider Arrangement and Other Mortgage Fees
Some mortgage deals come with arrangement, valuation or legal costs.
These should be considered alongside the headline rate.
Check Early Repayment Charges
Leaving a fixed deal early can trigger an early repayment charge.
Depending on the mortgage, that charge may outweigh the benefit of switching.
Think About Your Future Plans
If you are planning to move home, reduce the mortgage or make other major changes, that could affect which deal makes sense.
How Early Should You Review Your Mortgage Deal?
It is usually sensible to start looking before your current deal expires.
Can You Secure a Mortgage Rate Before Your Current Deal Ends?
Some lenders may allow you to secure a new mortgage deal several months in advance.
This can give you more time to compare options.
What Happens if Mortgage Rates Fall Before Completion?
Depending on the lender and application stage, you may be able to review whether a different deal is available.
This is something a mortgage broker can help you check.
How Do Interest Rates Affect Mortgage Affordability?
Higher mortgage rates can reduce the amount some borrowers are able to afford.
Impact on First Time Buyers
Higher repayments can make affordability checks more challenging, particularly where deposits are smaller.
Impact on Home Movers
Home movers may find that the cost of borrowing affects the size of mortgage available for the next property.
Impact on Existing Homeowners
Existing homeowners may notice the biggest change when a fixed deal ends and a new rate is required.
Affordability Checks When Remortgaging
Lenders normally assess income, outgoings, debts and other financial commitments when considering a remortgage application.
Can Loan to Value Affect the Mortgage Rate You Receive?
Loan to value, or LTV, compares your mortgage balance with the value of the property.
How Your Deposit Affects LTV
A larger deposit usually means a lower LTV.
Some lenders offer different rates depending on the LTV band.
How Building Equity Could Affect Your Options
If your property has increased in value or you have reduced the mortgage balance, your LTV may improve.
That could give you access to a wider range of mortgage options.
Should You Overpay Your Mortgage When Interest Rates Are High?
Overpaying can reduce the balance on which interest is charged.
Check Your Overpayment Allowance
Some mortgage deals limit how much you can overpay without a charge.
Consider Early Repayment Charges
Always check the terms before making a large additional payment.
Keep Enough Emergency Savings
Reducing your mortgage can be useful, but it is also important to keep enough savings for unexpected costs.
Can a Mortgage Offer Change or Be Withdrawn?
Yes, a lender may reconsider an offer in some circumstances.
Changes to Your Financial Circumstances
A major change in income, employment or borrowing could affect the application.
Affordability and Credit Checks
Lenders may carry out further checks before completion.
Changes Before Completion
If your circumstances change, tell your adviser or lender as early as possible.
How Can a Mortgage Broker Help When Interest Rates Change?
A mortgage broker can help you understand how changing rates affect the options available to you.
Comparing Mortgage Deals
A broker can compare suitable mortgage products based on your circumstances.
Reviewing Your Existing Mortgage
This can include checking your current rate, remaining term and any charges for leaving early.
Understanding Fees and Charges
The headline interest rate is only one part of the cost.
Finding a Mortgage That Fits Your Circumstances
Manchester Mortgages can help review available options based on your income, deposit, mortgage balance, future plans and other relevant factors.

Review Your Mortgage Before Your Current Deal Ends

If your current deal is ending, your payments have changed or you simply want to understand your options, Manchester Mortgages can review your existing mortgage and help you compare suitable routes.
Your home may be repossessed if you do not keep up repayments on your mortgage.
