When you hear that the Bank of England has changed the base rate, you might wonder how this affects your mortgage payments. The base rate is the UK’s official interest rate, set by the Bank of England’s Monetary Policy Committee (MPC). It is one of the key tools used to manage inflation and economic stability.
In simple terms: when the base rate goes up, borrowing usually becomes more expensive; when it goes down, borrowing tends to become cheaper. But the impact on your mortgage depends on the type of deal you have and your individual circumstances.
What is the Bank of England base rate?
The base rate is the interest rate that the Bank of England charges commercial banks and other lenders when they borrow money. Because these institutions then pass on costs to their customers, the base rate influences the rates offered on mortgages, savings accounts, loans, and credit cards.
The MPC meets roughly every six weeks to review the economic outlook, including inflation levels, wage growth, and overall market conditions. Any change they make to the base rate tends to ripple quickly through the financial system.
How the Base Rate Affects Different Types of Mortgages
1. Tracker Mortgages
A tracker mortgage follows the Bank of England base rate directly, plus a set percentage. For example, if your tracker is “base rate +1%” and the base rate is 4% (as it is at the time of writing), you’ll pay 5%. When the base rate rises or falls, your monthly repayments will move almost immediately in line with it.
2. Standard Variable Rate (SVR) Mortgages
If you are on your lender’s SVR, your rate is not tied strictly to the base rate but is influenced by it. Lenders generally increase or decrease their SVR shortly after a base rate change. The timing and scale of the adjustment are at the lender’s discretion, which can make budgeting less predictable.
3. Fixed-Rate Mortgages
With a fixed-rate mortgage, your monthly repayments remain unchanged for the length of your fixed term, regardless of what happens to the base rate. However, when your fixed deal ends and you move onto the SVR (unless you remortgage), you could see a significant change in costs depending on the prevailing base rate.
4. Discount Mortgages
Discount mortgages are linked to a lender’s SVR rather than the base rate itself. This means you pay the SVR minus a set percentage. Because SVRs are usually influenced by the base rate, your payments may still fluctuate after a base rate change.
What a Rise in the Base Rate Means
- Higher monthly repayments for those on tracker or SVR mortgages.
- Reduced affordability when applying for a new mortgage, as lenders stress-test applicants against higher potential rates.
- Impact on remortgaging options, since new fixed-rate deals are usually priced based on market expectations of where the base rate is heading.
What a Fall in the Base Rate Means
- Lower monthly repayments for many borrowers on tracker or SVR mortgages.
- Potentially cheaper new mortgage deals, though lenders may not pass on the full reduction.
- Improved affordability in affordability tests, which can help first-time buyers or those looking to borrow more.
Why This Matters for Homeowners and Buyers
Because your mortgage is likely to be the largest financial commitment you’ll ever take on, even a small change in the base rate can make a noticeable difference to your budget. For example, a rise of 0.25% on a repayment mortgage of £200,000 over 30 years could increase payments by £41.66 per month, depending on your product type. Over the course of a year, that adds up significantly.
Understanding how the base rate interacts with your mortgage is crucial for making informed decisions about remortgaging, fixing your rate, or exploring alternative products.

The Role of a Qualified Mortgage Adviser
Interpreting how the base rate affects your specific mortgage can be complex. A qualified mortgage adviser can:
- Explain how base rate changes impact your current deal.
- Assess whether switching to a fixed rate could protect you from future rises.
- Search the whole market for competitive deals suited to your circumstances.
- Guide you through affordability checks and stress testing.
- Help you plan long-term, ensuring your mortgage remains sustainable even if rates change again.
Unlike going directly to a bank or lender, an independent adviser considers a wide range of products and lenders, giving you broader choice and impartial advice.
Key Takeaway: How the Base Rate Affects Mortgages
The Bank of England base rate influences mortgage costs by affecting how much lenders charge for borrowing. If the base rate rises, tracker and variable mortgage repayments usually increase. If it falls, they often decrease. Fixed-rate mortgage holders are protected until their deal ends, but future options will be shaped by the prevailing base rate.
Because the financial impact can vary widely between borrowers, speaking with a qualified mortgage adviser is the best way to understand your options and protect yourself from unnecessary costs.
Final Thoughts
The Bank of England’s base rate is more than just a headline in the news—it directly affects your mortgage repayments and your future borrowing potential. With rates reviewed every six weeks, homeowners and buyers need to stay informed and prepared for changes.
If you are unsure how a base rate change will affect you, or if you want to review your current mortgage deal, contact a qualified mortgage adviser. Their expertise can help you navigate the market, compare lenders, and secure a mortgage that suits your financial goals.
