How Remortgaging Works in the UK | Costs, Process & Key Considerations

Before looking at why someone may consider remortgaging, it’s helpful to understand what remortgaging actually is.

Remortgaging is the process of replacing an existing mortgage with a new one, either with the same lender or a different lender. In the UK, most mortgages are arranged with an initial product period, commonly two, three or five years, although longer terms such as seven or ten years are also available.

When this initial period ends, if no action is taken, the mortgage will usually revert to the lender’s standard variable rate (SVR). This rate is set by the lender and can change at any time.

For many borrowers, the end of a product period is a natural point to review their mortgage. However, remortgaging is not always the right option for everyone, and whether it is suitable will depend on individual circumstances.

Common Reasons People Consider Remortgaging

Reaching the End of an Initial Rate

One of the most common reasons people look at remortgaging is when their fixed, tracker or discounted rate is coming to an end.

Moving onto a lender’s standard variable rate may result in higher monthly payments, although this is not always the case. Reviewing available options at this stage allows borrowers to understand whether a new product may better suit their needs.

Releasing Equity from a Property 

Some homeowners consider remortgaging to release equity from their property. This may be used for purposes such as home improvements or other personal expenditure.

Increasing the mortgage balance can have long-term cost implications, so it is important to consider affordability both now and in the future.

Seeking Payment Certainty

During periods of economic uncertainty, some borrowers prefer the predictability of a fixed rate mortgage. Fixing the interest rate for a longer period can provide certainty over monthly payments, although this may limit flexibility and could result in early repayment charges.

Changing Mortgage Type

Others may consider switching mortgage types, for example from a fixed rate to a tracker or variable rate, based on their expectations of future interest rate movements.

Interest rates are unpredictable, and decisions should be made with an understanding of both the potential risks and benefits.

What Costs Can Be Involved in Remortgaging? 

Remortgaging can involve similar costs to taking out a mortgage initially. These may include:

• Mortgage product or arrangement fees
• Valuation fees
• Legal or conveyancing costs
• Advice or broker fees, where applicable
• Exit fees from the existing lender, such as early repayment charges

Some lenders offer incentives such as free valuations, free legal work, or cashback. While these can reduce upfront costs, they should be considered alongside the overall cost of the mortgage, including the interest rate and product features.

Focusing solely on the lowest rate may not always result in the most suitable outcome.

How Do Lenders Assess Affordability When Remortgaging?

If you are remortgaging to a new lender, affordability is typically assessed in a similar way to when you originally purchased the property.

Lenders will usually review:

• Income, whether employed or self-employed
• Existing financial commitments, such as loans, credit cards, car finance and childcare costs
• Credit history and repayment conduct

Each lender applies its own criteria, which means borrowing limits and available products can vary. Understanding your financial position before applying can help avoid unnecessary declines.

What Happens If You Do Nothing?

If no action is taken when a mortgage product ends, the loan will usually move onto the lender’s standard variable rate.

This rate is often higher than other available products, although it may offer greater flexibility, such as the ability to overpay or redeem the mortgage without early repayment charges.

In some situations, remaining on the standard variable rate may be appropriate, for example if a borrower plans to move home in the near future or expects a change in circumstances.

The key consideration is awareness. Knowing what rate you will move onto and understanding whether it aligns with your plans is important.

Key Points to Consider Before Remortgaging

• Remortgaging involves replacing your existing mortgage with a new one
• The end of an initial rate is a common review point, but not the only one
• Costs, flexibility and long-term affordability should all be considered
• Doing nothing may result in higher payments, but can offer short-term flexibility
• What is suitable will depend on your individual circumstances
