What is a fixed rate mortgage?

As a prospective homebuyer in the UK, it is essential to understand the variety of mortgage options available to you. One popular option is the fixed rate mortgage. In this article, we will delve into the world of fixed rate mortgages, exploring what they are, the benefits and drawbacks, and why they might be suitable for you.


What is a fixed rate mortgage?

A fixed rate mortgage is a type of mortgage where the interest rate remains constant for a predetermined period. This period can range from two to ten years, depending on the mortgage product you choose. During this fixed rate period, your monthly mortgage repayments will not change, providing you with stability and predictability in your financial planning.

Once the fixed rate period ends, your mortgage will typically revert to the lender’s Standard Variable Rate (SVR), which is subject to change based on market conditions. At this point, you may choose to remortgage to another fixed rate product or consider other mortgage options.

How does it work?

Here’s a breakdown of how a fixed-rate mortgage works:

Interest rate: The interest rate on a fixed-rate mortgage is agreed upon at the time of taking out the loan and remains unchanged for the entire term. This provides predictability and stability for the borrower, as their monthly payments will not fluctuate due to changes in market interest rates.

Monthly payments: The monthly payment on a fixed-rate mortgage is determined by the principal amount borrowed, the interest rate, and the loan term. This payment consists of both principal repayment and interest. In the early years of the loan, a larger portion of the payment goes towards interest, while later in the loan term, more of the payment goes towards repaying the principal.

Amortisation schedule: An amortisation schedule is a table that shows the breakdown of each monthly payment into principal and interest over the life of the loan. As you progress through the loan term, the interest portion of the payment decreases while the principal portion increases.

Loan term: Fixed-rate mortgages are available in various terms, typically ranging from 2 to 10 years, with 2 and 5-year terms being the most common. Shorter loan terms generally have lower interest rates but higher monthly payments, while longer loan terms have higher interest rates but lower monthly payments.

Prepayment: Some fixed-rate mortgages allow borrowers to make additional payments towards the principal without incurring prepayment penalties. This can help reduce the overall interest paid and shorten the loan term.


Budgeting certainty: With a fixed rate mortgage, you can confidently plan your monthly expenses without worrying about fluctuations in interest rates. This stability allows you to manage your finances more effectively.

Protection from interest rate increases: If market interest rates rise, your fixed rate mortgage will shield you from the impact of increased costs. This security can be especially appealing during periods of economic uncertainty or when interest rates are predicted to rise.

Flexible terms: Fixed rate mortgages are available in various term lengths, offering you the flexibility to choose a product that aligns with your financial goals and circumstances.


Limited benefits from interest rate decreases: If market interest rates fall, you will not benefit from reduced mortgage repayments, as your fixed rate will remain constant throughout the term.

Early repayment charges: Fixed rate mortgages often come with early repayment charges if you decide to pay off your mortgage or switch to another product before the end of the fixed term. These charges can be substantial and may outweigh any potential savings from switching.

Potentially higher initial rates: Fixed rate mortgages can sometimes have higher interest rates than their variable counterparts, particularly when market interest rates are low. This means that you could be paying more for the stability and certainty provided by the fixed rate.

Advantages of fixed rate mortgages

Fixed-rate mortgages offer several advantages to borrowers, making them a popular choice for many homebuyers. Some of the key advantages include:

Predictability and stability: Since the interest rate remains constant throughout the entire loan term, your monthly mortgage payments will not change. This predictability allows you to create a stable budget and plan your finances with greater ease.

Protection from rising interest rates: If market interest rates rise during the term of your fixed-rate mortgage, you are protected because your interest rate will not change. This can potentially save you money compared to an adjustable-rate mortgage (ARM), which may see an increase in monthly payments due to rising interest rates.

Easier comparison: Fixed-rate mortgages are easier to compare than adjustable-rate mortgages, as the terms and interest rates are clearly defined. This simplifies the process of shopping for a mortgage and selecting the best deal for your financial situation.

Simplified decision-making: With a fixed-rate mortgage, you don’t need to worry about when to lock in your rate, as the interest rate remains constant throughout the loan term. This can reduce stress and anxiety related to fluctuating interest rates and market conditions.

Suitable for long-term planning: If you plan to stay in your home for an extended period or prefer the certainty of a fixed payment, a fixed-rate mortgage can be an ideal choice. This type of mortgage allows you to plan for the long term, knowing that your payments will remain consistent.

Build equity: In the early years of a fixed-rate mortgage, a larger portion of your monthly payment goes towards paying off the interest. Over time, the proportion of your payment allocated to principal repayment increases, allowing you to build equity in your home at a predictable rate.

Easy to understand: Fixed-rate mortgages are relatively straightforward and easy to understand compared to some other mortgage products, such as adjustable-rate mortgages, which may have complex terms and conditions.

While fixed-rate mortgages offer several advantages, it’s important to note that they may not be the best option for everyone. They generally come with higher interest rates compared to the initial rates of adjustable-rate mortgages, and you won’t benefit from decreasing interest rates unless you refinance. Additionally, the predictability and stability of fixed-rate mortgages may be less crucial to those who plan to move or refinance within a short period.

Disadvantages of fixed rate mortgages

While fixed-rate mortgages offer several advantages, they also come with certain disadvantages that borrowers should consider when choosing a product. Some of the key disadvantages include:

Higher initial interest rate: Fixed-rate mortgages typically have higher initial interest rates compared to adjustable-rate mortgages (ARMs), which often start with a lower “teaser” rate. This means you may pay more in interest, especially during the initial years of the mortgage.

No benefit from falling interest rates: If market interest rates decrease, your fixed-rate mortgage interest rate will remain unchanged. To take advantage of lower interest rates, you would need to refinance your mortgage, which involves additional costs, such as closing costs and potential prepayment penalties.

Limited flexibility: Fixed-rate mortgages come with less flexibility compared to adjustable-rate mortgages, which may offer features such as interest-only payment periods or payment caps. With a fixed-rate mortgage, your payment structure is set for the entire loan term, making it less adaptable to changing financial circumstances.

Potential for prepayment penalties: Some fixed-rate mortgages have prepayment penalties if you pay off the loan early, refinance, or make additional principal payments beyond your regular monthly payments. These penalties can be costly, so it’s essential to review your loan agreement to understand any potential charges.

Less suitable for short-term homeowners: If you plan to move or sell your home within a few years, a fixed-rate mortgage may not be the best option. The higher initial interest rate and potential prepayment penalties can make it less cost-effective than an adjustable-rate mortgage with a lower initial rate.

Opportunity cost: By choosing a fixed-rate mortgage, you may miss out on the potential savings offered by an adjustable-rate mortgage if interest rates remain low or decrease during the loan term.

Longer approval process: Due to the stability and predictability of fixed-rate mortgages, they may be in higher demand, leading to a longer approval process in some cases, particularly during periods of low interest rates.

When considering a fixed-rate mortgage, it’s essential to weigh both the advantages and disadvantages in the context of your personal financial situation, preferences, and goals. An informed decision can help you select the mortgage product that best meets your needs and contributes to long-term financial stability.

Is a fixed rate mortgage right for you?

Choosing a fixed rate mortgage ultimately depends on your individual circumstances and financial goals. If you value stability and predictability in your monthly expenses, a fixed rate might be a suitable option. Additionally, if you expect interest rates to rise in the near future, a fixed rate could protect you from higher repayments.

However, if you anticipate interest rates to decrease or you plan to make significant changes to your mortgage (such as overpaying or remortgaging) within the fixed rate term, a variable rate mortgage may be a more suitable choice.

In summary, a fixed rate mortgage offers stability and predictability for UK homebuyers, making it an attractive option for those who value certainty in their financial planning. It is essential to weigh the benefits and drawbacks against your individual circumstances and financial goals when deciding whether a fixed rate is right for you.
