What Is a Repayment Mortgage? Complete Guide for First-Time UK Homebuyers

September 2, 2025

Buying a first home is an exciting yet often daunting experience, especially when it comes to understanding the different types of mortgages. One of the most common and straightforward mortgage types in the UK is the repayment mortgage, also known as a capital repayment mortgage or full repayment mortgage. If you have ever wondered what is a repayment mortgage  what is a capital repayment mortgage  or what is the repayment on a mortgage  this comprehensive guide is tailored for you.

What Is a Repayment Mortgage?

A repayment mortgage is the most traditional mortgage type where your monthly repayments cover both the mortgage capital (the amount you borrowed) and the interest on the loan. Over the term of the mortgage—usually 25 years but variable—your payments reduce the loan amount until the mortgage is completely paid off by the end of the term.

Because each payment includes capital repayment, you gradually build equity in your home, providing security and a clear path to eventual homeownership without any outstanding debt.

What Is a Capital Repayment Mortgage?

A capital repayment mortgage is simply another name for a repayment mortgage. The “capital” refers to the loan principal you borrowed. Your monthly repayments consist of this original loan amount plus the interest charged by your lender.

The importance of capital repayment lies in knowing that each payment lowers your loan balance, unlike an interest-only mortgage where your loan remains the same until you pay it off in full at the end.

How Does Mortgage Repayment Work?

Your monthly mortgage repayment is calculated by combining the interest charged on your outstanding loan with a portion that goes toward reducing the capital. Early in the mortgage term, a larger percentage of your payment goes to interest, while later payments increasingly contribute to paying down the capital.

This amortization schedule means you steadily decrease your debt over time, offering predictability both for your finances and your home’s future.

What Is the Repayment on a Mortgage? Example for £150,000 Loan

For a mortgage of £150,000, monthly repayments vary depending on the interest rate and term length.

For example:

  • At a 3% fixed rate over 25 years, your monthly repayment would be roughly £711.
  • At a 4% fixed rate over 25 years, this rises to about £792.

Using a mortgage calculator can help you get precise figures based on current rates and personalized borrowing terms.

What Is a Full Repayment Mortgage?

A full repayment mortgage is just another term for a repayment (or capital repayment) mortgage. It emphasizes that by the end of your mortgage term, you will have repaid the entire loan amount plus interest, leaving you with full ownership of your property outright.

This contrasts with interest-only mortgages, where the principal must be repaid separately, often through savings or investment plans.

Why Choose a Repayment Mortgage?

The repayment mortgage remains popular among first-time UK homebuyers because it offers:

  • Security through gradual equity build-up.
  • A clear exit path after the mortgage term.
  • Peace of mind that you won’t owe a lump sum at the end.
  • Easier mortgage approvals due to lower lending risk.

If you want detailed guidance on securing your mortgage and early financial planning, start with understanding what is an agreement in principle, as this is usually the first step in mortgage approval.

Dealing with Leasehold Issues and Legal Nuances

Some properties, especially flats or older homes, may operate on leaseholds which introduce complexities like lease expiry. Understand your rights at what happens when a leasehold expires to avoid surprises.

Repayment Mortgage Challenges and What to Avoid

Sometimes, borrowers encounter confusion between agreement in principle and final mortgage approval. Not every agreement in principle leads to mortgage sanction, so thorough preparation of documents and finances is essential.

Unexpected issues might arise, but informed buyers can manage them smoothly.
