What is the remortgage process?

The remortgage process, step by step

A remortgage (sometimes called a “switch” or “re-mortgage”) is when you replace your existing mortgage with a new one—often to change the interest rate, term, or borrowing structure. While every case is different, the overall process tends to follow a similar path.

Below is a practical overview of what typically happens from the first application through to completion.

1) Planning your remortgage

Before you apply, it helps to clarify what you want to achieve. Common reasons include:

• securing a more competitive interest rate
• changing from a fixed rate to a different deal type (or vice versa)
• adjusting the term to manage monthly payments or total cost
• borrowing additional funds (where permitted)
• consolidating certain debts into the mortgage (subject to lender rules)

At this stage, lenders and advisers will also consider factors such as your current mortgage balance, remaining term, payment history, and any early repayment charges that may apply.

2) Submitting the remortgage application

Once you’ve selected the mortgage you want to apply for, the lender will require information to assess affordability and risk. This usually includes:

• proof of income and employment details
• details of your existing mortgage
• information about your outgoings and financial commitments
• identification and residency information
• credit history checks

If you’re remortgaging with additional borrowing or your circumstances have changed, the lender’s questions may be more detailed.

3) Lender assessment and underwriting

After the application is submitted, the lender reviews the information provided. This is often referred to as underwriting. The lender may:

• request further documents
• clarify unusual income or expenditure
• consider the property type and how it’s used
• review any credit-related matters

The time taken at this stage can vary depending on how straightforward the application is and how quickly any additional information is provided.

4) Valuation of the property

Most remortgages require a valuation. The purpose is to confirm the property’s value and ensure it meets the lender’s lending criteria.

A valuation may be:

• a desktop valuation (based on available information)
• a surveyor-led valuation (more detailed)

If the valuation comes in lower than expected, it can affect the loan amount or the mortgage offer terms. In some cases, further discussion or a revised application may be needed.

5) Mortgage offer issued

If the lender is satisfied with the application and valuation, it issues a mortgage offer. This offer sets out the key terms, including:

• the loan amount
• the interest rate and deal type
• repayment method and term
• any conditions that must be met before completion

It’s important to review the offer carefully, particularly where there are conditions attached.

6) Instructing legal work

Even though you’re not buying a new home, remortgages still involve legal processes because the lender needs security over the property.

Legal work typically includes:

• preparing and progressing the mortgage deed and related documents
• handling the change of lender arrangements
• dealing with any requirements from the lender’s legal team
• coordinating with your existing lender (where relevant)

Your solicitor or conveyancer will guide you through what’s needed and keep the process moving.

7) Signing the mortgage deed

Once the legal documents are ready and any conditions are satisfied, you’ll be asked to sign the mortgage deed. This is a key step because it confirms your agreement to the mortgage terms.

Signing can be completed in different ways depending on the legal process being used.

8) Completion and funds transfer

Completion is when the remortgage is finalised and the funds are transferred.

In many cases, the new lender’s funds are used to repay the existing mortgage, and the remaining balance (if any) is handled according to the mortgage agreement.

After completion, your new mortgage account will be active, and you’ll start making payments under the new terms.

What can affect the remortgage timeline?

While the steps above are typical, the time it takes can vary. Common factors include:

• how quickly documents are provided
• complexity of income or financial circumstances
• whether the valuation is straightforward
• how quickly legal work progresses
• any conditions attached to the mortgage offer
• the timing of your current mortgage end date and any early repayment charges

A general overview—your journey may differ

This is a general outline of the remortgage process. The exact steps, order, and timing can vary depending on the lender, the property, and the nature of the remortgage.

If you’re considering a remortgage, understanding each stage can make the process feel more manageable and help you plan around key milestones.

Your home may be repossessed if you do not keep up repayments on a mortgage or any other debt secured on it.
