A remortgage is when you replace the mortgage on a property you already own with a new mortgage. In everyday use, people often say “remortgage” when they are reviewing their current deal, but there is an important distinction:

• Remortgage: you usually move your mortgage to a new lender.
• Product transfer or rate switch: you stay with your current lender and choose a new deal.
• Further advance: you borrow more from your existing lender, if they agree.

People usually look at remortgaging when a fixed, tracker or discount deal is ending, when they want to borrow more, when their property value has changed, or when their circumstances mean the current mortgage no longer fits.

This guide is general information only and is not personal mortgage advice. Your options depend on your income, credit history, property, equity, affordability, lender criteria and the mortgage market when you apply. Your home may be repossessed if you do not keep up repayments on your mortgage.

What does remortgaging mean in practice?

Remortgaging means arranging a new mortgage on the same property rather than buying a different home. The new mortgage repays the old mortgage, and you continue living in the property unless you are remortgaging a buy-to-let or another property you do not occupy.

A remortgage can be used to:

• move to a new interest rate deal
• avoid moving onto a lender’s standard variable rate
• change your mortgage term
• move from interest-only to repayment, or sometimes the other way round if suitable
• borrow more against your home
• remove or add a borrower, where the lender allows this
• review your mortgage after a change in income, employment, relationship or future plans

A remortgage is not only about finding the lowest rate. Lenders also look at affordability, property value, loan-to-value, credit history, income evidence and the purpose of any extra borrowing.

public guidance explains that shopping around or getting advice can help borrowers compare mortgage options, but the right route depends on the whole cost and suitability of the deal, not just the headline rate: public guidance: choosing a mortgage and getting advice.

Remortgage, product transfer or do nothing?

When your current deal is ending, you normally have three broad options.

A product transfer can be quicker because you remain with your current lender. Some lenders may not require the same level of underwriting for a like-for-like switch, but this varies. If you want to borrow more, change the term, change repayment type or remove someone from the mortgage, the lender may carry out more checks.

A remortgage to a new lender can open up more choice, but it can also involve more work. You may need a valuation, legal work, new affordability checks and updated documents.

A common trap: chasing a remortgage before checking the fallback

Imagine a homeowner whose fixed rate ends in five months. They want to remortgage to a new lender because they have seen a lower headline rate and would also like to raise money for home improvements. On the face of it, that sounds like a normal remortgage conversation.

The trap is that several details could change the answer. Since taking the original mortgage, they have taken out car finance, one partner has reduced hours after returning from parental leave, and their house value is based on optimistic online estimates rather than a lender valuation. They also still have an early repayment charge if the new mortgage completes too soon.

A broker would not just ask, “Which lender has the lowest rate?” The practical checks would be:

• Can the new lender’s affordability model support the current balance plus the extra borrowing?
• What happens if the valuation comes in lower and the loan-to-value moves into a different band?
• Does the early repayment charge wipe out any benefit of switching now?
• Is the purpose and amount of extra borrowing acceptable to the lender?
• Is the current lender’s product transfer a useful backup if the full remortgage does not fit?

The lesson is that a remortgage is not automatically better than staying put. A new lender may offer more choice, but it also means fresh underwriting, valuation and legal work. For some borrowers, the best decision is to line up a product transfer as a safety net while testing whether a full remortgage genuinely improves the overall position.

Is remortgaging a good idea?

It can be, but not always. A remortgage may be worth exploring if the overall benefit outweighs the costs, risks and disruption.

A remortgage may be less attractive if:

• you are still tied into a deal with a large early repayment charge
• your current lender offers a suitable product transfer with lower fees
• your income has reduced and a new lender would lend less than you need
• your credit position has worsened
• the property may be difficult for lenders to accept
• you plan to move soon and need portability or a short-term route
• the fees outweigh the benefit of switching

The Bank of England’s Bank Rate can influence the wider interest rate environment, but mortgage pricing also depends on lender funding, competition, product type and risk appetite. You can read more about Bank Rate here: Bank of England: Bank Rate.

Do you get money when you remortgage?

You do not automatically receive money when you remortgage. In many cases, the new mortgage simply replaces the old mortgage balance.

You may receive additional funds if you remortgage for a higher amount than your current mortgage balance and the lender agrees. This is sometimes described as releasing equity, although it is different from later-life equity release products.

Example:

• Estimated property value: £300,000
• Current mortgage balance: £170,000
• Proposed new mortgage: £200,000
• Extra borrowing before fees and charges: £30,000

Whether this is possible depends on affordability, loan-to-value, credit checks, the lender’s criteria and the reason for the extra borrowing.

Common reasons for additional borrowing include:

• home improvements
• buying out an ex-partner’s share, where legally and financially suitable
• raising funds for another property purchase
• restructuring existing borrowing
• supporting major life costs, where the lender accepts the purpose

Be careful with debt consolidation. Moving unsecured debts into a mortgage can reduce monthly payments, but it may increase the total amount repaid if the debt is spread over a longer term. It also turns unsecured borrowing into debt secured against your home.

What do lenders check when you remortgage?

A lender will usually assess whether the mortgage is affordable, suitable for their criteria and secured on an acceptable property.

Common checks include:

• your income and employment type
• your regular commitments and debts
• your credit history
• your current mortgage conduct
• the property value and condition
• the loan-to-value
• the remaining mortgage term
• the repayment type, such as repayment or interest-only
• the purpose of any additional borrowing
• legal title, leasehold details or ownership changes where relevant

If you are self-employed, a lender may ask for tax calculations, tax year overviews, accounts or business bank statements. GOV.UK provides general information on self-assessment here: GOV.UK: Self Assessment tax returns.

If the property is leasehold, lenders may also look at lease length, ground rent, service charges and legal restrictions. GOV.UK has general leasehold information here: GOV.UK: leasehold property.

How does the remortgage process work?

The exact process depends on the lender and your circumstances, but a typical remortgage review follows this order:

1. Check your current mortgage balance, rate, term and deal end date.
2. Confirm whether an early repayment charge or exit fee applies.
3. Estimate the current property value.
4. Calculate your loan-to-value.
5. Review your income, debts, credit position and future plans.
6. Compare your current lender’s product transfer options with suitable remortgage options.
7. Check total cost, not just the monthly payment.
8. Submit an application if a suitable route is identified.
9. Complete valuation, underwriting and legal work where required.
10. The new mortgage completes and repays the old mortgage.

Straightforward cases can be relatively simple. Cases involving additional borrowing, credit issues, self-employment, unusual property, leasehold concerns or changes to ownership can take longer.

When should you start looking at remortgaging?

Many borrowers start reviewing options several months before their current deal ends. This gives time to compare a product transfer with a new-lender remortgage and to deal with underwriting, valuation and legal work.

Starting early can help you avoid being forced into a rushed decision, but mortgage products and lender criteria can change. If you secure a deal in advance, check how long the offer lasts and whether it can still complete at the right time.

The key dates to check are:

• your current deal end date
• any early repayment charge end date
• your current lender’s product transfer window
• the expiry date of any new mortgage offer
• any deadline linked to a separation, property transfer or planned works

public guidance has guidance on early repayment and overpayment issues here: public guidance: should you pay off your mortgage early?.

What can make remortgaging harder?

A remortgage can become more difficult where the lender sees higher risk or where the case does not fit standard criteria.

The Financial Conduct Authority provides consumer information on financial services and regulated firms here: FCA: consumers.

What is loan-to-value and why does it matter?

Loan-to-value, often shortened to LTV, is the mortgage amount compared with the property value.

For example:

• Mortgage balance: £180,000
• Property value: £300,000
• Loan-to-value: 60%

LTV matters because lenders often price mortgage products in bands. A lower LTV may give access to a wider choice of products, but it does not guarantee acceptance. Affordability, credit profile, property type and lender criteria still matter.

If the lender’s valuation is lower than expected, your LTV may be higher than you planned. That can affect the products available or the amount you can borrow.

What costs should you compare?

Do not compare remortgage options by rate alone. A lower rate with a high fee is not always better than a higher rate with a lower fee.

Check:

• interest rate
• monthly payment
• arrangement fee
• valuation fee
• legal costs
• cashback
• broker fee, if applicable
• early repayment charge on your current mortgage
• exit or discharge fee from your current lender
• total cost over the deal period
• overpayment limits
• portability if you may move home
• whether the product has features you value, such as offset or flexible payments

A useful question is: what will this cost me over the period I expect to keep the deal, and what flexibility am I giving up?

What documents make remortgaging easier?

Having the right documents ready helps an adviser or lender assess the case properly.

A practical checklist:

• latest mortgage statement
• current mortgage offer or product details
• current balance, rate, term and deal end date
• details of any early repayment charge
• estimate of current property value
• payslips and P60 if employed
• accounts, tax calculations and tax year overviews if self-employed
• recent bank statements
• details of loans, credit cards, car finance and other commitments
• proof of identity and address
• buildings insurance details, if requested
• leasehold information, if relevant
• clear explanation of any additional borrowing purpose
• details of any missed payments, defaults or credit issues

If your case involves separation, adding or removing a borrower, or changing ownership, you may also need legal advice. Mortgage advice and legal advice are separate.

What would a broker check first?

A broker would usually start with the facts that change lender choice:

The aim is not to force a remortgage. The aim is to compare the realistic routes and avoid applying to a lender that does not fit the facts.

What are the main risks of remortgaging?

The main risks are not always obvious from the headline rate.

This is why a remortgage decision should include cost, criteria, timing and future flexibility.

What could remortgaging look like in practice?

Here are simplified examples. They are not recommendations.

Example 1: straightforward deal ending

A borrower has a fixed rate ending in four months. Their income is stable, credit history is clean and they do not need extra borrowing. The main comparison is between a product transfer and a new-lender remortgage.

The right decision would depend on total cost, fees, timing and product features.

Example 2: borrowing more for home improvements

A borrower wants to raise £25,000 for a kitchen extension. The lender will look at the new total mortgage, affordability, property value and whether the works make sense for the case.

The borrower should compare monthly payment, total interest, fees and the impact of extending the debt over the mortgage term.

Example 3: income has changed

A borrower’s current deal is ending, but they have recently become self-employed. A product transfer may be simpler, but it may not offer the best overall outcome. A new lender may require trading history and tax evidence.

The key is to check lender criteria before applying.

Example 4: separating from a partner

One borrower wants to keep the home and remove the other from the mortgage. This is not just a rate switch. The lender must assess affordability in the remaining borrower’s name, and legal work may be needed to deal with ownership.

Independent legal advice may also be required depending on the circumstances.

What do generic remortgage guides often miss?

Many guides explain the definition but do not go far enough on the decision. The practical question is not just “what is a remortgage?” It is “which route fits my numbers, evidence and plans?”

A stronger review should cover:

• product transfer versus new-lender remortgage
• total cost over the deal period
• early repayment charges and fees
• lender affordability and credit criteria
• property valuation risk
• whether extra borrowing is suitable
• future plans, such as moving, overpaying or changing work
• what happens if the preferred lender or valuation does not work

How should you prepare before asking for advice?

Before speaking to an adviser, write down:

• your current lender
• current mortgage balance
• current interest rate
• monthly payment
• remaining term
• deal end date
• early repayment charge, if any
• estimated property value
• reason for remortgaging
• whether you want extra borrowing
• income and employment details
• any credit issues or missed payments
• whether you may move home soon

This makes the conversation more useful and helps separate realistic options from routes that are unlikely to fit.

If you are approaching the end of a fixed, tracker or discount deal, speak to us before you apply. We can help you compare a product transfer with a full remortgage and look at the costs, criteria and timing before you commit.

What is the strongest next step?

The strongest next step is to check three things before choosing a product:

1. Does remortgaging actually beat staying with your current lender?
2. Will the lender’s criteria fit your income, credit profile, property and borrowing purpose?
3. What is the total cost, including fees, charges and future flexibility?

If those questions are answered clearly, remortgaging becomes a practical mortgage decision rather than a rush to chase a headline rate.

FAQs

What is a remortgage?

A remortgage is when you replace the mortgage on a property you already own with a new mortgage. It usually means moving to a new lender, although people sometimes use the word more loosely when reviewing their current deal.

Is a remortgage the same as a product transfer?

No. A remortgage usually means moving to a new lender. A product transfer means choosing a new deal with your existing lender. Both can be useful, depending on cost, criteria, timing and your plans.

Is remortgaging a good idea?

It can be, but it depends on your circumstances. A remortgage may help if it gives you a suitable deal, better structure or acceptable additional borrowing. It may not be worthwhile if fees, early repayment charges or lender criteria outweigh the benefit.

Do you get money when you remortgage?

Not automatically. You only receive extra money if you borrow more than your current mortgage balance and the lender agrees. This depends on affordability, property value, loan-to-value, credit checks and the purpose of the extra borrowing.

Can I borrow more when I remortgage?

You may be able to borrow more, but it is not guaranteed. Lenders will check affordability, credit history, property value and the reason for the extra borrowing. Extra borrowing increases the debt secured against your home.

Can I remortgage to consolidate debts?

Some lenders may consider this, but it needs careful advice. Consolidating debts into a mortgage may reduce monthly payments, but it can increase the total amount repaid over time and secure previously unsecured debts against your home.

Do I need a solicitor for a remortgage?

A remortgage to a new lender usually involves legal work because the old lender’s charge must be removed and the new lender’s charge registered. Some lenders include basic legal work as part of a remortgage package, but this depends on the product and the case.

Will remortgaging affect my credit score?

A full mortgage application may involve a hard credit search. The effect depends on your wider credit profile and how the credit reference agencies record the search. Making several applications in a short period can be unhelpful, so it is sensible to check lender fit before applying.

Can I remortgage if my income has reduced?

Possibly, but it may be harder. A new lender will assess affordability using your current income and commitments. If your income has reduced, a product transfer with your existing lender may be worth comparing, but it still depends on the lender and the changes you want to make.

Can I remortgage if I am self-employed?

Yes, self-employed borrowers can remortgage, but lenders usually want evidence of income. This may include accounts, tax calculations, tax year overviews and bank statements. Criteria vary between lenders.

Can I remortgage with bad credit?

It may be possible, depending on the type, date, amount and explanation of the credit issue. Missed payments, defaults, county court judgments or high credit use can restrict lender choice and affect pricing. Get advice before applying.

What happens if my property value has fallen?

A lower valuation can increase your loan-to-value and may reduce the products available. If the property is worth less than the mortgage balance, this is negative equity, and remortgaging to a new lender may be difficult. Your current lender may still have options, but this depends on their rules.

Can I remortgage before my fixed rate ends?

You can apply before your fixed rate ends, but completing the remortgage too early may trigger an early repayment charge. Many borrowers review options in advance and time completion for when the charge no longer applies.

How long does a remortgage take?

Timescales vary. A straightforward remortgage can be quicker than a purchase, but valuation, underwriting, legal work, leasehold issues or additional borrowing can add time. Start early if your current deal is ending.

Can a remortgage be refused?

Yes. A lender can decline a remortgage if the case does not meet affordability, credit, property, valuation or criteria requirements. Approval cannot be guaranteed.

Should I speak to a broker?

It can be useful, especially if you are borrowing more, self-employed, have credit issues, own a non-standard or leasehold property, or are unsure whether a product transfer or remortgage is better. A broker can help compare lender fit, costs and timing.
