How to remortgage your property

If your current mortgage deal is coming to an end, remortgaging can be a way to review your options and take control of your monthly payments. It usually involves switching your existing mortgage to a new deal—either with your current lender or a different one—without moving house.

This guide explains what remortgaging is, when it’s worth looking at options, the reasons people remortgage, and how a broker can help you manage the process.

What is remortgaging?

Remortgaging is the process of replacing your existing mortgage with a new mortgage arrangement.

Most remortgages are done on the same property, meaning:

the mortgage remains secured against your home
you may change your interest rate, product type, or term
if you move to a new lender, you’ll typically go through a new application process

How remortgaging options are influenced

Your potential options are often shaped by factors such as:

Loan-to-value (LTV): how much you owe compared with the property value
Your mortgage balance and remaining term
Your income and affordability
The type of product you’re considering (for example, fixed or tracker)

In general, borrowers with lower LTVs may have access to a wider range of products.

Why people remortgage

While many remortgages are done to secure a new rate as a deal ends, there are other common reasons to review your mortgage.

Common remortgage motivations include:

Staying off your lender’s standard variable rate (SVR): when a fixed or tracker deal ends, payments can change significantly
Stabilising monthly costs: choosing a fixed rate for predictability
Releasing equity: for home improvements, renovations, or other major spending
Debt consolidation: replacing certain debts with a mortgage-based solution (where appropriate)
Raising funds for a property plan: such as supporting a second property or investment plans

It’s also possible to combine objectives—for example, securing a new rate while borrowing additional funds for improvements.

When should you look into remortgaging?

Timing matters because mortgage offers and product availability can take time to arrange.

A practical approach is to start reviewing your options before your current deal ends. Mortgage offers are typically issued with a validity period, so it’s important to understand the timeframe attached to any offer you receive.

If you’re on a fixed or tracker deal

When a fixed or tracker period is nearing its end, reviewing options early can help you avoid being pushed onto your lender’s SVR.

If you’re already on SVR

If you’re already paying an SVR rate, it’s usually worth looking at alternatives as soon as possible, as there may be opportunities to reduce your monthly payments by switching to a new product.

How a mortgage broker helps with remortgaging

A remortgage can involve more paperwork and checks than many borrowers expect—especially if you move lender. A broker’s role is to help you navigate the process and focus on options that fit your circumstances.

Market access and product matching

A broker can assess your situation and consider products across the market, helping narrow down what’s most suitable based on factors like:

your LTV and remaining term
your preferred repayment structure
whether you want a fixed rate for stability or another product type
any additional borrowing you’re considering

Handling the application process

If you move lender, a remortgage typically involves a new application and affordability assessment. A broker can help by:

preparing and submitting the application
helping ensure supporting information is provided promptly
managing communication with the lender through to the mortgage offer

Managing the switch

Once a mortgage offer is in place, the legal process is usually handled through a solicitor appointed for the transaction. Completion then leads to the new mortgage funds being used to repay the existing mortgage, with repayments moving to the new lender.

A broker can help you understand the sequence of events so there are fewer surprises along the way.

What to consider before you remortgage

Before choosing a new deal, it helps to think about the full picture—not just the headline rate.

Key areas to review include:

Early repayment charges (if applicable): if you’re remortgaging before your current deal ends, charges may apply
Fees and costs: some deals include arrangement fees that may be added to the loan
The repayment structure: capital repayment versus interest-only (where available)
The term of the new mortgage: extending or shortening the term can affect affordability and total cost
How long you plan to stay in the property: a shorter time horizon may influence whether a longer fixed term is worth it

A worked example (illustrative)

To show how remortgaging can work in practice, consider an example scenario.

The situation

A couple’s current fixed rate ends in a few months
They have built up equity in their home (around 20%)
They want to avoid moving onto SVR
They also want to fund home improvements

The approach

They review options and arrange a new fixed-rate remortgage with a lender that can provide an offer period that fits their timeline. The remortgage is structured so the new rate is in place after the existing deal ends, helping avoid unnecessary costs.

They also include additional borrowing as part of the remortgage to support the planned improvements.

The outcome

By switching to a new fixed rate and using the remortgage to fund improvements, they aim to:

keep monthly payments more predictable
reduce the risk of a payment increase associated with SVR
access funds without needing to take separate borrowing for the project

Note: This is an illustrative example. Your exact options, costs and timelines will depend on your circumstances and the lender’s criteria.

Common remortgaging pitfalls to avoid

Remortgaging is often successful, but issues can arise when key details are overlooked.

Things to watch for:

Leaving it too late: delays can increase the risk of being moved onto SVR
Not checking offer validity: mortgage offers may expire if completion doesn’t happen within the stated timeframe
Focusing only on rate: fees, term changes, and product features can materially affect the overall cost
Underestimating paperwork: affordability checks and supporting documents can take time
Ignoring the impact of additional borrowing: it can change LTV and affect which products are available

Final thoughts

Remortgaging is often about timing and fit: reviewing your options before your current deal ends, understanding what you want to achieve, and choosing a mortgage structure that aligns with your circumstances.

A broker can help you compare suitable pathways, manage the application process, and keep the remortgage moving through to completion—so you can secure a new deal with less stress and clearer expectations.
