What types of mortgages are available in the UK?

Navigating the mortgage market can be complex, but understanding the core types available in the UK is the essential first step towards property ownership. Mortgages are primarily defined by two dimensions: how you repay the capital (the borrowed amount) and how the interest rate is calculated.

What Types of Mortgages are Available in the UK?

In the UK, mortgages are highly customisable, allowing lenders to tailor products to suit diverse financial circumstances. While specific niche products exist, all mortgages fall into primary categories based on how you pay back the loan and how the interest rate behaves.

The Two Primary Repayment Methods

When securing a mortgage, you must choose how you intend to pay back the loan amount over the agreed term (typically 25 years, but often longer or shorter).

1. Capital and Interest (Repayment) Mortgage

This is the most common and safest type of mortgage for most UK borrowers. Each monthly payment consists of two parts:

• Capital: A portion goes towards reducing the original loan amount.
• Interest: A charge based on the amount still owed.

As you consistently make payments, the outstanding balance shrinks. Assuming you meet all repayments, the loan will be fully paid off at the end of the agreed term, and you will own the property outright.

2. Interest-Only Mortgage

With an interest-only mortgage, your monthly payments cover only the interest charged on the loan. The original capital amount borrowed remains constant throughout the mortgage term. This usually results in lower monthly payments compared to a capital and interest mortgage.

However, this option carries significant risk, as the original debt must be repaid in full at the end of the term. Lenders require a clear and credible “repayment vehicle” or “exit strategy” to demonstrate how you intend to repay the capital. Common strategies include using investments (like ISAs or endowments) or selling the property itself. If the exit strategy fails or the investment underperforms, you could face difficulties repaying the principal sum.

Understanding Interest Rate Structures

The second key decision involves how the interest rate you are charged is determined. This dictates how much your monthly payments will cost and how vulnerable you are to changes in the wider economic climate, such as Bank of England base rate adjustments.

Fixed-Rate Mortgages

A fixed-rate mortgage locks your interest rate for a specific period, usually two, three, five, or ten years. During this fixed term, your monthly repayments remain the same, regardless of what happens to the Bank of England Base Rate.

Benefits: Provides stability and makes budgeting easier, as you know exactly what your housing costs will be. Risks: You may miss out if market interest rates fall, and most fixed-rate products charge significant early repayment charges (ERCs) if you choose to switch provider or pay off the mortgage early during the fixed term.

Variable-Rate Mortgages

Variable-rate products mean your interest rate, and thus your monthly payment, can change at any time. There are several common types of variable rates:

• Tracker Mortgages: These rates are explicitly linked to the Bank of England Base Rate (BoE BR) plus a set percentage margin. If the BoE BR rises by 0.25%, your mortgage rate will also rise by 0.25%. They often have a limited term, similar to fixed rates.
• Standard Variable Rate (SVR): This is the default rate a lender moves you onto once your introductory fixed or tracker deal ends. The SVR is set entirely by the lender and is not directly tied to the BoE BR, although it is influenced by it. SVRs are typically higher than introductory rates, and lenders can change them whenever they wish.
• Discounted Rate Mortgages: These offer a discount off the lender’s SVR for an introductory period (e.g., 2% off the SVR for two years). While cheaper initially, your rate can still fluctuate if the lender chooses to change its SVR.

Specialist Mortgage Categories

Beyond the primary structures, certain types of mortgages cater to specific situations or property uses.

Buy-to-Let (BTL) Mortgages

If you plan to purchase a property specifically to rent it out, you will require a BTL mortgage. These are assessed differently from residential mortgages. Lenders typically focus less on the applicant’s personal salary and more on the rental income the property is expected to generate, often requiring the rent to cover 125% to 145% of the mortgage payment. BTL mortgages are often interest-only and are generally subject to different regulatory requirements.

Shared Ownership Mortgages

Designed to help those who cannot afford to buy a property outright, shared ownership allows you to purchase a share (e.g., 25% to 75%) of a home from a housing association and pay rent on the remaining share. You take out a mortgage on the purchased share and can typically buy more shares over time, a process known as ‘staircasing’.

Bridging Finance

Bridging loans are short-term, secured loans typically used to “bridge” a gap between the sale of one property and the purchase of another, or for quick property acquisitions (such as auction purchases) before long-term finance is secured. These are high-interest, short-term solutions (often 1 to 18 months).

Key Aspects of Bridging Loans:

• Interest Roll-Up: Unlike residential mortgages, interest on bridging loans is usually added to the total loan amount rather than paid monthly. This means the total debt increases over the term.
• Risk Warning: Bridging finance is secured against property. Your property may be at risk if repayments are not made. Consequences of default can include legal action, repossession, increased interest rates, and additional charges.

Factors Affecting Mortgage Eligibility

Regardless of the type of mortgage you seek, lenders assess your application based on four critical areas:

1. Affordability: Lenders are required by the Financial Conduct Authority (FCA) to stress-test your finances to ensure you could afford the repayments even if interest rates rose significantly. This check often reviews all aspects of your spending. You can find independent tools to check your affordability via the government-backed MoneyHelper service. Check the MoneyHelper mortgage affordability calculator here.
2. Deposit/Loan-to-Value (LTV): The deposit you contribute determines the Loan-to-Value ratio (LTV), which is the loan amount divided by the property value. A lower LTV (meaning a larger deposit) generally unlocks more favourable interest rates.
3. Credit History: Lenders assess your financial track record, looking for evidence of timely repayment of debts, defaults, or bankruptcies. A strong credit score is essential for accessing the best rates. It is wise to check your file well in advance of applying: Get your free credit search here.

4. Property Condition: The type and condition of the property (e.g., non-standard construction, flying freeholds) can limit the types of mortgages available, as lenders need assurance that the property provides adequate security for the loan.

People also asked

What is the typical mortgage term in the UK?

While mortgage terms can vary widely, the most standard term chosen by UK homeowners is 25 years. However, terms of 30, 35, or even 40 years are becoming increasingly common, particularly among first-time buyers seeking to reduce their monthly payments.

What is Loan-to-Value (LTV)?

Loan-to-Value (LTV) is the ratio of the loan amount relative to the value of the property, expressed as a percentage. For example, if you borrow £180,000 to buy a £200,000 property, the LTV is 90% (£180,000 ÷ £200,000). The lower the LTV, the less risky the loan is perceived to be by the lender, which typically results in lower interest rates.

What is the difference between a mortgage broker and a lender?

A mortgage lender (like a bank or building society) provides the actual capital for the loan. A mortgage broker acts as an intermediary, helping you compare products from multiple lenders and guiding you through the application process to find the most suitable deal for your circumstances.

Can I get a mortgage if I am self-employed?

Yes, self-employed individuals can secure mortgages, but the application process is often more detailed. Lenders typically require two to three years of certified accounts or SA302 tax calculations to prove income stability and affordability, sometimes requiring a larger deposit compared to employed applicants.

What are early repayment charges (ERCs)?

Early Repayment Charges (ERCs) are fees imposed by lenders if you pay off your mortgage or switch to a new product outside of a short window of time, particularly while you are still within an introductory fixed or tracker rate period. ERCs are usually calculated as a percentage of the outstanding loan balance.

Choosing the Right Mortgage Type

Selecting the appropriate mortgage type depends on your personal financial strategy and risk appetite. Fixed-rate, capital and interest mortgages offer maximum certainty and safety, making them ideal for those on a tight budget or those new to homeownership.

Conversely, interest-only and variable-rate products may offer lower initial costs but demand greater financial resilience and a tolerance for potential repayment increases. Consulting with an independent, qualified mortgage adviser is highly recommended to assess the full range of options available in the UK market and determine the best fit for your unique situation.
