Whether you’re a first-time buyer, an existing homeowner or thinking about remortgaging, you’ve probably heard the term Bank of England Base Rate mentioned in the news.

But what does the Base Rate actually mean for your mortgage?

When the Bank of England changes its Base Rate, it can have an impact on borrowing costs across the UK. However, the effect on your mortgage will depend on the type of mortgage you have, your current interest rate and when your existing deal is due to end.

In this guide, we’ll explain how Bank of England Base Rate changes can affect different types of mortgages and what you may want to consider if you’re reviewing your mortgage options.

What is the Bank of England Base Rate?

The Bank of England Base Rate is the interest rate set by the Bank of England’s Monetary Policy Committee.

It influences the cost of borrowing and saving across the economy and can affect the interest rates offered by banks and mortgage lenders.

The Bank of England may raise interest rates when it wants to put downward pressure on inflation. Conversely, it may reduce rates when economic conditions change and lower borrowing costs are considered appropriate.

Because mortgage lenders take a range of factors into account when setting their rates, a change to the Base Rate does not necessarily mean that every mortgage rate will change by the same amount.

So, how could a Base Rate change affect you?

That largely depends on your mortgage type.

How does a Base Rate increase affect your mortgage?

If the Bank of England increases the Base Rate, the impact on your mortgage will depend on whether your interest rate is fixed or variable.

Fixed-rate mortgages

With a fixed-rate mortgage, your interest rate is fixed for an agreed period.

This means your mortgage payments will generally remain the same throughout your fixed-rate period, even if the Bank of England Base Rate rises.

For example, if you have a five-year fixed-rate mortgage, an increase in the Base Rate during those five years would not normally change the interest rate you pay on your existing mortgage.

This can provide valuable certainty when managing your household budget.

However, there is an important consideration: what happens when your fixed-rate deal ends?

If you need to remortgage when interest rates are higher than when you originally secured your mortgage, your new monthly payments could be higher.

This is why it can be useful to review your mortgage options before your current deal expires.

How do tracker mortgages respond to Base Rate changes?

A tracker mortgage typically follows the Bank of England Base Rate, usually with a set percentage added to it.

For example, a tracker mortgage could be priced at the Base Rate plus a fixed margin.

If the Base Rate rises, your mortgage interest rate — and potentially your monthly payments — could increase.

If the Base Rate falls, your mortgage rate could also decrease, depending on the terms of your mortgage.

Because tracker mortgage payments can move up or down, they can offer potential benefits when interest rates fall but also carry the risk of higher payments when rates rise.

If you’re considering a tracker mortgage, it’s important to make sure you could still afford your repayments if interest rates increased.

What about Standard Variable Rate mortgages?

A Standard Variable Rate (SVR) is an interest rate set by your mortgage lender.

While an SVR may be influenced by changes to the Bank of England Base Rate, it does not necessarily move by the same amount or at exactly the same time.

If you are currently on your lender’s SVR, it may be worth reviewing whether another mortgage deal could be more suitable for your circumstances.

In some cases, borrowers move onto an SVR automatically when their fixed or introductory mortgage deal ends.

This can sometimes mean paying a higher interest rate than you might find through alternative mortgage products, although the right option will depend on your individual circumstances and the deals available at the time.

What happens to mortgage rates when the Base Rate falls?

A fall in the Bank of England Base Rate can be positive news for some borrowers.

If you have a tracker mortgage or another type of mortgage linked to the Base Rate, your interest rate may fall, potentially reducing your monthly payments.

However, the relationship between the Base Rate and mortgage rates is not always straightforward.

Mortgage lenders consider a range of factors when pricing their products. This means that a Base Rate reduction does not necessarily mean all mortgage rates will immediately fall by the same amount.

For homeowners on fixed-rate mortgages, there may be no immediate change to their existing monthly payments because their rate is fixed until the end of the agreed period.

What if your fixed-rate mortgage is coming to an end?

For many homeowners, the end of a fixed-rate mortgage is one of the most important times to review their finances.

When your fixed-rate period ends, you may need to choose a new mortgage deal. Depending on the rates available at the time, your new mortgage payment could be higher, lower or similar to your current payment.

It’s worth starting the process early.

By reviewing your options before your current deal expires, you may have more time to understand the products available and consider what works best for your circumstances.

A mortgage adviser can also help you assess your options and explain the potential costs involved in switching mortgage deals.

Could a Base Rate change increase your mortgage payments?

The answer depends on your mortgage.

If you’re on a fixed-rate deal, your monthly payments are generally protected during the fixed period.

If you’re on a tracker mortgage, your payments may change when the Base Rate changes.

If you’re on an SVR, your lender may change the rate in response to market conditions and other factors.

The potential impact of an interest rate change will also depend on:

Your outstanding mortgage balance
Your current interest rate
The type of mortgage you have
The remaining term of your mortgage
Whether your mortgage is repayment or interest-only
The size of any interest rate change
Your lender’s specific terms and conditions

A change that has a relatively small impact on one homeowner could make a much bigger difference to another, particularly where a larger mortgage balance is involved.

What should you do when the Bank of England changes the Base Rate?

If you’re concerned about how a Base Rate change could affect you, there are several practical steps you can take.

1. Check what type of mortgage you have

Start by finding out whether you’re on a fixed-rate, tracker or variable-rate mortgage.

Your mortgage offer or annual statement should provide details about your current rate and when your deal is due to end.

2. Check when your current deal ends

If you’re on a fixed-rate mortgage, make a note of the date your fixed period expires.

It’s worth reviewing your options ahead of this date rather than waiting until your mortgage automatically moves to your lender’s SVR.

3. Review your monthly budget

Consider how your finances would cope if your mortgage payments increased.

This can be particularly important if you’re considering a variable-rate or tracker mortgage.

4. Check for mortgage fees

Before switching mortgage products, check whether you could face an early repayment charge, arrangement fee, valuation fee or other costs.

The cheapest-looking interest rate isn’t always the cheapest overall option once all fees are taken into account.

5. Get professional advice

Mortgage products and lending criteria can change over time, and the right mortgage for one person may not be suitable for another.

A qualified mortgage adviser can review your circumstances, explain your options and help you understand the potential costs of changing your mortgage.

How can a mortgage adviser help?

Understanding the Bank of England Base Rate is useful, but knowing what it means for your individual mortgage is even more important.

A mortgage adviser can help you:

Review your current mortgage
Understand how interest rate changes could affect your payments
Explore remortgage options
Compare available mortgage products
Consider fixed-rate and variable-rate options
Review your mortgage before your current deal expires
Explain potential fees and early repayment charges

The mortgage market can change quickly, so getting an early understanding of your options can help you make a more informed decision.

Final thoughts: Don’t wait until your mortgage deal expires

Changes to the Bank of England Base Rate can affect mortgage borrowers in different ways.

If you’re on a fixed-rate mortgage, you may not see an immediate change to your payments. If you’re on a tracker or variable-rate mortgage, your repayments could be more directly affected.

The key is to understand what type of mortgage you have, when your current deal ends and what your options could be.

If your fixed-rate period is coming to an end, or you’re concerned about how changing interest rates could affect your finances, now could be a good time to review your mortgage.
