Remortgage guides

Remortgaging is often one of the most practical ways to review your mortgage without moving house. Whether you’re approaching the end of a fixed rate, considering borrowing more, or looking to change how your mortgage works, the outcome usually depends on choosing the right route at the right time.

This guides hub brings together the main remortgage approaches and the decisions that can make a difference—so you can compare options and understand what to expect.

Remortgaging summary

What is a remortgage?

A remortgage is when you switch your mortgage deal while keeping the same property. That can happen in two broad ways:

• Switching to a new lender
• Staying with your current lender by moving to a different product (often called a product transfer or deal switch)

Why do people remortgage?

Most remortgages are driven by one of two goals:

1. Reducing the interest rate—particularly to avoid moving onto a higher rate when your current deal ends.
2. Borrowing more—for example for home improvements or to consolidate other debts.

In practice, remortgaging can also be used to restructure the mortgage term or repayment type, depending on what you’re trying to achieve.

Remortgage timing: when to start looking

A common approach is to start reviewing options around 3–6 months before your current deal ends. That window can help you:

• compare suitable options across lenders,
• understand the costs that may apply, and
• plan so your new deal starts when your existing term finishes.

If you’re considering leaving a fixed-rate deal early, timing becomes more sensitive because early repayment charges (ERCs) may apply. In many cases, the closer you are to the end of the deal, the smaller the ERC impact tends to be.

Switching deals vs switching lenders

One of the first decisions is whether to:

• do a product transfer with your existing lender, or
• switch lenders to access different mortgage features.

Both routes can be appropriate. The right choice often depends on how your circumstances have changed since you took out your mortgage, such as:

• your loan-to-value (LTV),
• affordability and income position,
• whether you want a different mortgage structure (for example, fixed vs variable), and
• whether you need additional borrowing.

Key costs to consider

Remortgaging isn’t only about the interest rate. The overall cost can be influenced by fees and charges that vary by lender and by your situation.

Early repayment charges (ERCs)

If you leave your current mortgage deal before the end of the introductory period, you may pay an ERC. For some borrowers, ERCs can reduce or remove the benefit of switching early—so it’s important to consider the net benefit, not just the headline rate.

Lender and arrangement fees

Depending on the deal and lender, you may encounter costs such as:

• arrangement fees (sometimes paid upfront or added to the mortgage),
• booking or application fees, and
• fees linked to the specific mortgage product.

Legal and conveyancing costs

If you switch lenders, you’ll typically need a solicitor or conveyancer to handle the legal work involved in transferring the mortgage. Product transfers with the same lender can sometimes involve less legal complexity, but the process still depends on the lender and the type of change.

How LTV affects remortgage options

Your loan-to-value (LTV) is the percentage of your property value that you’re borrowing. Lenders use LTV to price risk, which means it can affect what deals you’re offered.

LTV can improve over time as:

• you repay your mortgage balance, and/or
• your property value changes.

A lower LTV doesn’t guarantee a better deal, but it can broaden the options available and influence pricing.

Remortgage repayment comparisons: what to look at

A remortgage calculator can help you estimate how repayments might change when you move from your current rate to a new one.

When comparing scenarios, it’s useful to focus on the inputs that typically matter most:

• outstanding mortgage balance,
• remaining term,
• your current interest rate, and
• the proposed new interest rate.

Repayment figures are only as accurate as the information entered and may not include every fee or product feature. For a fuller picture, it’s the combination of repayments and total remortgage costs that matters.

When a remortgage may not be the best move

Remortgaging can be worthwhile, but there are situations where switching immediately may not make sense. Common examples include:

• ERCs are high compared with the savings you expect,
• your circumstances have changed in a way that makes it harder to qualify for the amount you need,
• your mortgage balance is relatively small, where fees and charges can reduce the benefit, or
• you plan to move soon, because switching costs may not be recovered before the property is sold.

Remortgage options for different goals

Remortgaging can be used for more than just rate changes. The best approach depends on what you want to achieve.

Reduce monthly payments

Many borrowers remortgage to reduce monthly outgoings—particularly when a fixed or introductory rate ends. However, the lowest rate isn’t always the best outcome once you factor in fees, ERCs and the length of the new deal.

Borrow additional funds

Some homeowners remortgage to borrow more against the property value. This can support major expenses such as home improvements or debt consolidation.

Whether additional borrowing is possible depends on factors like affordability, property value and lender requirements.

Debt consolidation

Consolidating debts into a mortgage can simplify finances, but it can also change the overall cost depending on the term and interest rates involved. It’s important to consider both monthly affordability and the longer-term picture.

Fund home improvements

If you want to spread the cost of renovations, remortgaging can sometimes be a way to fund improvements through the mortgage rather than using separate borrowing.

Reduce the mortgage term

Some borrowers remortgage to shorten the remaining term. This can reduce total interest paid over time, but it often increases monthly payments—so affordability needs to be considered carefully.

Remortgage considerations for more complex situations

Not all remortgages are straightforward. Certain circumstances can affect lender availability and how applications are assessed.

Remortgaging with less-than-perfect credit

It may still be possible to remortgage with a credit history that isn’t perfect. Lenders typically consider the type of credit issue, how long ago it happened, and your current financial position.

Buy-to-let remortgages

Buy-to-let remortgaging is assessed differently from residential lending. Rental income, property type and portfolio factors can all influence what’s available.

Later life remortgages

Some borrowers consider remortgaging later in life to reduce monthly commitments, release equity, or adapt the mortgage structure to retirement plans. Lender approaches can vary, so it’s helpful to understand the options that align with your situation.
