What happens when your UK mortgage product ends, and what is a remortgage?

This is a question overseas buyers often overlook, and yet it matters a great deal. Many clients taking out a UK mortgage for the first time assume that once the loan is approved, the monthly payment will simply be collected by the lender until the balance is cleared. Most UK mortgage products do not work that way. Common products in the UK market, such as a two-year fixed rate, a three-year fixed rate or a five-year fixed rate, each run for a fixed-rate period. When that period ends and the borrower takes no action, the loan normally reverts to the lender’s standard variable rate (SVR). The SVR is often higher than many of the new products then available in the market, which is why most UK homeowners review their mortgage before the product ends. That review is what people in the UK call a remortgage.

What is a remortgage?

In simple terms, a remortgage does not mean buying a property again. It means choosing a new mortgage. As the existing product approaches its end date, the owner can apply for a new one. Some clients stay with their existing lender, which is known as a product transfer; others move to a different lender, depending on what the market offers. Ownership of the property does not change. What changes is the mortgage product itself.

Why do so many UK owners remortgage?

The most common reasons are set out below.

To obtain a more suitable rate

The mortgage market moves with the UK economy and with interest rates. When a new product better matches an owner’s requirements, many will consider rearranging their borrowing.

To adjust the term

As income, family circumstances or future plans change, some clients want to shorten the term and clear the loan sooner, while others prefer to extend it and ease the monthly payment. A remortgage allows the borrowing to be reshaped around a different stage of life.

To change the repayment method

Some clients start on an interest-only mortgage and later wish to move to a repayment mortgage. Others want to restructure their borrowing around an investment plan. A remortgage is the point at which these options can be considered.

To fit the family’s wider asset planning

For investors, a remortgage is not only about reducing the rate. Some release part of the equity that has built up in the property and use it to buy another home, improve the property they live in, or make other long-term investments. Whether such an arrangement is appropriate depends on the client’s financial position and on professional advice.

When should you start preparing for a remortgage?

Our usual advice is not to wait until the existing product has ended. Many mortgage advisers suggest looking at the market several months before the product expires and gathering the necessary documentation in advance. That leaves time to compare products properly and avoids slipping onto the SVR simply for want of preparation. Exactly how far ahead to start depends on the individual product and on your adviser’s guidance.

In business since 2015: what clients overlook is not the mortgage, but what happens when it ends

Since 2015 we have seen many overseas clients spend a great deal of time on the questions of whether a mortgage can be obtained and at what rate, and then pay almost no attention to the product once the loan is in place. In reality, a UK mortgage offer is not the end of the relationship with the lender. It is the beginning of a long period of management. When does the product end? When can a new one be selected? When is the right moment to remortgage? Each of these questions affects a family’s finances for years. We therefore encourage clients to record the key dates of their mortgage product, rather than waiting for the lender to write to them.

SJW Insight

Since 2015 we have become increasingly convinced that a UK mortgage is not a one-off financial arrangement. It is closer to a long-term financial product that requires ongoing management. Genuinely professional mortgage planning does not end when the loan is approved. It continues over the following years, as interest rates, family cash flow, asset allocation and personal plans all change. At SJW UK Properties we therefore encourage clients not to think of a remortgage as a remedy applied after a product has expired, but as part of long-term asset management. For many families, a well-judged remortgage does more than improve the terms of their borrowing. It gives the family more control over its own financial planning.
