Remortgage advice means getting a regulated recommendation on whether to switch mortgage deal, stay with your current lender, borrow more, change term, change repayment type, or wait.
The right answer is rarely just “choose the lowest rate”. It depends on your current mortgage, early repayment charges, fees, property value, income, credit profile, future plans and what lenders are prepared to offer when you apply.
Plain English: good remortgage advice should reduce the risk of choosing the wrong route. It should help you compare the total cost, check lender fit and avoid timing problems before an application goes in.
This guide is general information only and is not personal mortgage advice. Your options depend on your circumstances, the property and lender criteria at the time.
Key takeaway: Remortgage advice means getting a regulated recommendation on whether to switch mortgage deal, stay with your current lender, borrow more, change term, change repayment type, or wait.
What should remortgage advice actually cover?
Remortgage advice should help you answer five practical questions:
-
Should you change anything at all?
Sometimes the best option is to switch deal. Sometimes it is to stay with your current lender. Sometimes it is to wait. -
Should you use a product transfer or a full remortgage?
A product transfer means changing deal with your current lender. A full remortgage usually means moving your mortgage to a new lender. -
What is the true cost?
You need to compare interest rate, product fee, valuation fee, legal costs, broker fee, cashback, early repayment charges and any exit fees. -
Will the lender’s criteria fit your case?
Lenders normally look at affordability, income evidence, credit commitments, credit history, loan-to-value, property type and the purpose of any extra borrowing. -
Does the mortgage fit your future plans?
A deal that looks attractive today may be less suitable if you plan to move, sell, repay a lump sum, become self-employed, retire soon or borrow more later.
public guidance explains that mortgage costs should be considered as part of your wider household budget, not just the headline payment. GOV.UK’s home-buying guidance also highlights that lenders assess whether mortgage repayments are affordable. The same broad principle applies when you remortgage.

When should you start looking at remortgage options?
Many borrowers start reviewing options around six months before their current deal ends, but the right timing depends on your lender, your current mortgage terms and how complicated your case is.
A simple product transfer may be quick. A full remortgage can involve affordability checks, a valuation, legal work and underwriting, so it is sensible not to leave it until the last minute.
Practical remortgage timeline
| Time before current deal ends | What to do | Why it matters |
|---|---|---|
| 6 months | Check your current balance, rate, deal end date, early repayment charge and remaining term | This tells you when switching may make sense and what it could cost |
| 5–6 months | Estimate your property value and loan-to-value | LTV can affect which product tiers may be available |
| 4–5 months | Compare current lender product transfer options with wider remortgage options | The simplest route is not always the best value, and the cheapest-looking route may not fit |
| 3–4 months | Gather income, bank, credit and property documents | Missing documents can delay underwriting |
| 2–3 months | Submit the chosen application if appropriate | Allows time for valuation, legal work and lender queries |
| Final month | Check completion timing and avoid gaps where possible | Helps reduce the risk of moving onto a standard variable rate unnecessarily |
Some mortgage offers are valid for a limited period, and some lenders allow deals to be reserved in advance. Exact rules vary, so check before relying on a general timeframe.

Product transfer or full remortgage: which route should you compare?
A key part of remortgage advice is deciding whether to stay with your existing lender or move elsewhere.
| Option | What it means | When it may suit | What to watch |
|---|---|---|---|
| Product transfer | You switch to a new deal with your current lender | You want a simpler route, have limited time, or your circumstances have become harder to evidence | It may not be the lowest total cost or most flexible option |
| Full remortgage | You move your mortgage to a new lender | Another lender may offer better overall value, criteria or flexibility | Full affordability, valuation and legal work may apply |
| Further advance | You borrow more from your current lender | You need extra funds and your current lender’s criteria fit | Extra borrowing may be on a different rate, term or product |
| Remortgage with extra borrowing | You move lender and increase the mortgage balance | You want to raise funds and restructure the mortgage | The lender will assess affordability, purpose of funds and LTV |
| Stay as you are temporarily | You do not switch immediately | You are moving soon, waiting for documents, or the costs of switching are not justified | You may move onto a standard variable rate, which could be higher |
A product transfer can be attractive because it may involve less paperwork and fewer checks. But you should still compare the overall cost where appropriate.
A full remortgage may be more suitable if another lender offers better total value or criteria that fit your plans. However, it normally involves a fresh lender assessment and is not guaranteed.

Which costs and risks matter when remortgaging?
Do not compare remortgage options by rate alone. A lower rate with a high fee can cost more than a slightly higher rate with no fee, especially on smaller mortgage balances.
Costs to check before you switch
| Cost or feature | Why it matters |
|---|---|
| Early repayment charge | You may pay a charge if you leave your current deal during the tie-in period |
| Exit fee or account fee | Some lenders charge an administration fee when the mortgage is repaid |
| Arrangement or product fee | This can change the true cost of a low-rate deal |
| Valuation fee | Some lenders include a basic valuation; others may charge |
| Legal fees | Some remortgages include standard legal work, but more complex cases may cost more |
| Broker fee | If applicable, it should be disclosed clearly before you proceed |
| Cashback or incentives | Useful, but should be weighed against the full cost |
| New tie-in period | Important if you may move, sell, repay early or change the mortgage soon |
| Overpayment rules | Check how much you can overpay without a charge |
| Portability | Useful if you may move, but porting is normally subject to lender approval at the time |
The Bank of England Bank Rate influences the wider interest rate environment, but mortgage rates do not all move in the same way or at the same time. Fixed-rate pricing can also be affected by funding costs, swap rates, lender margins and competition.
If you are unsure whether to switch, make an enquiry and we can help you compare the practical options before you commit to an application.

Who is remortgage advice relevant for?
Remortgage advice may be useful if:
- your fixed-rate, tracker or discount deal is coming to an end
- you are already on your lender’s standard variable rate
- you want to compare a product transfer with a full remortgage
- you are considering borrowing more against your home
- your income, employment, credit profile or family circumstances have changed
- you want to reduce monthly payments, shorten the term or review your repayment strategy
- you are worried about higher payments when your current deal ends
- you are planning to move and need to understand portability or early repayment charges
- you are consolidating debt and need to understand the risks
- your property is leasehold, non-standard or affected by building safety issues
James Blackler at The Mortgage Blog often recommends starting with the facts rather than the rate table: current balance, property value, remaining term, deal end date, early repayment charges, income, committed outgoings and future plans. Without those details, it is easy to compare the wrong mortgage.

When might you not need broker-led remortgage advice?
You may not need a broker-led review if:
- your remaining mortgage balance is small
- your existing lender is offering a straightforward product transfer that clearly meets your needs
- your income, credit file, property and affordability position are uncomplicated
- you do not need to borrow more or change the mortgage structure
- you are comfortable comparing total costs, tie-in periods and fees yourself
- you understand what happens if rates or your plans change
Even then, it is worth checking the total cost rather than assuming the lowest rate is best.
There are also cases where remortgaging may not be the right route at all. If you plan to move very soon, taking a new fixed-rate product with early repayment charges could create avoidable cost unless the mortgage is portable and the lender agrees to the future move. Portability is not automatic; the lender will usually reassess your circumstances and the new property when you apply to port.
If you are in serious payment difficulty, speak to your existing lender as soon as possible. The FCA sets rules for mortgage firms, including how firms should treat customers. You may also wish to seek independent debt guidance.

What information does a broker usually need before giving remortgage advice?
A broker needs enough information to judge affordability, lender fit, total cost and suitability.
Document checklist
| Area | Examples of information or documents |
|---|---|
| Current mortgage | Latest mortgage statement, balance, rate, deal end date, term and early repayment charge |
| Income | Payslips, P60, accounts, tax calculations, employment contract, pension income or benefit evidence where relevant |
| Self-employed income | SA302s or tax calculations, tax year overviews, accounts, business bank statements and company details where applicable |
| Spending and commitments | Loans, credit cards, car finance, childcare, maintenance, student loans and other regular commitments |
| Credit profile | Details of missed payments, defaults, CCJs, debt management plans or recent borrowing if applicable |
| Property | Estimated value, tenure, lease length, service charge, ground rent, cladding or building safety information where relevant |
| Extra borrowing | Amount required, purpose of funds and whether the term should match the main mortgage |
| Future plans | Moving, retirement, overpayments, family changes, expected income changes or planned property works |
Affordability
Lenders usually look at income, regular spending, credit commitments, dependants and the proposed mortgage payment. GOV.UK guidance notes that lenders check whether borrowers can afford mortgage repayments.
If you are employed, lenders commonly consider basic salary and may take a view on overtime, bonus or commission depending on consistency and evidence.
If you are self-employed, lenders may look at accounts, tax calculations, tax year overviews, company structure and trading history. HMRC’s Self Assessment guidance is relevant because tax documents are often used to evidence income.
Credit history
A lender will normally carry out a credit check. Missed payments, defaults, county court judgments, high credit utilisation, payday loans or recent unsecured borrowing can affect the options available.
This does not always mean you cannot remortgage. It means lender choice becomes more important, and the rate, maximum borrowing or available route may be affected.
Loan-to-value
Loan-to-value, or LTV, is the mortgage balance compared with the property value.
For example, a £180,000 mortgage on a £300,000 property is 60% LTV. A £240,000 mortgage on the same property is 80% LTV.
A lower LTV can sometimes open access to different product tiers, subject to lender criteria and market conditions. The lender will use its own valuation process, so the figure may differ from an estate agent estimate or online valuation.
Property type
The lender must be willing to lend on the property. Flats, leasehold homes, new-build properties, non-standard construction, ex-local authority flats, short leases, unusual title arrangements and properties affected by cladding or building safety issues may need closer review.
GOV.UK guidance on leasehold property and the building safety programme can be relevant where tenure, lease terms or building safety information affect the mortgage process.
Do not assume every lender will accept your property just because your current lender did in the past. Criteria can change.
Purpose of extra borrowing
If you want to borrow more, the lender will ask what the funds are for. Common reasons include home improvements, debt consolidation, buying another property or supporting a family member.
Debt consolidation needs particular care. It may reduce monthly outgoings, but it can also turn unsecured debt into borrowing secured against your home and may increase the total amount repaid if spread over a longer term. This is an area where personal advice is especially important.

What should you not do when remortgaging?
The biggest remortgage mistakes usually come from focusing on one part of the deal and missing the wider picture.
Do not only compare the interest rate
A low rate can be attractive, but fees and incentives can change the true cost. Compare the overall cost for the period you expect to hold the mortgage.
Do not leave it too late
If you wait until your current deal has ended, you may move onto your lender’s standard variable rate while you arrange a new mortgage. That may increase payments, depending on your existing deal and lender pricing.
Do not ignore early repayment charges
Leaving a fixed or discounted deal early can trigger a charge. Sometimes switching early may still be worth considering, but you need to calculate it carefully. Do not assume the new monthly payment tells the whole story.
Do not assume your current lender is automatically best
A product transfer can be a good solution, especially where speed or simplicity matters. But it should still be compared with the wider market where appropriate.
Do not assume a new lender will accept you
A full remortgage means fresh checks. If your income has changed, your credit file has worsened or your property is harder to mortgage, a new lender may take a different view.
Do not borrow more without checking the long-term cost
Extra borrowing can be useful, especially for planned home improvements. But increasing the mortgage balance, extending the term or consolidating short-term debt can increase long-term interest costs.
Do not choose a fixed rate without thinking about your plans
A longer fixed rate can provide payment certainty. But if you may move, sell, repay a lump sum or change the mortgage soon, early repayment charges and portability rules matter.
Do not extend the term just to reduce the payment
Extending the term can reduce monthly payments, but it may increase the total interest paid over the life of the mortgage. Shortening the term can reduce total interest, but it may increase monthly payments and affect affordability.

A common trap: the remortgage that looked simple until the timing changed
A homeowner has a fixed rate ending in five months and finds a cheaper-looking remortgage with a new lender. On paper, the monthly payment looks lower than their current lender’s product transfer, so they are tempted to apply immediately.
The difficulty is that the new lender’s offer would need to complete after the existing early repayment charge period ends. If the legal work or valuation runs early, completion timing has to be managed carefully. If it runs late, the borrower may spend time on the standard variable rate before the new mortgage completes.
There is another issue. During the application, the borrower takes out car finance because their old car fails its MOT. The new monthly commitment affects affordability, and the lender asks for updated bank statements before completion. At the same time, the lender’s valuation comes in lower than the borrower’s online estimate, pushing the case into a higher loan-to-value band.
The practical lesson is that a remortgage can change shape between “best rate found” and “ready to complete”. Before committing to a full remortgage, it is worth checking:
- the exact early repayment charge end date and required completion date
- how long the mortgage offer is valid for
- whether a product transfer can be held as a fallback
- whether any new borrowing, credit card spending or car finance is planned
- how sensitive the chosen deal is to the lender’s valuation
- whether leasehold, legal or title issues could slow completion
Good remortgage advice should identify these moving parts early, not only after an application has already been submitted.

What could remortgage advice look like in practice?
Example 1: Product transfer versus full remortgage
A borrower has £180,000 remaining on their mortgage and their fixed rate ends in four months. Their property is valued by the lender at £300,000, giving an approximate 60% LTV.
Their existing lender offers a product transfer with no legal work and no valuation fee. Another lender appears to offer a lower rate, but with an arrangement fee and a full remortgage process.
The right comparison is not simply the lower rate. The borrower needs to compare:
- monthly payment
- arrangement fee
- valuation and legal costs
- incentives
- any broker fee
- time and paperwork
- whether the new lender’s criteria fit
- the total cost over the chosen deal period
If the saving is small, the product transfer may be more practical. If the saving is meaningful and the borrower fits the new lender’s criteria, a full remortgage may be worth considering.
Example 2: Remortgaging to borrow more
A homeowner owes £220,000 and their property is valued at £400,000. They want to borrow an extra £40,000 for home improvements.
The proposed new borrowing would take the total mortgage to £260,000, which is 65% LTV based on the assumed value.
The lender will still need to assess affordability, income, credit commitments, property suitability and the purpose of funds. The borrower should compare whether a further advance from the current lender or a full remortgage gives better overall value.
A lower monthly payment is not enough on its own; the total interest cost and term also matter.
Example 3: Income has changed since the last mortgage
A borrower took out their current mortgage while employed full-time. Since then, they have become self-employed.
Their current lender may offer a product transfer without a full reassessment, depending on lender rules. A new lender may ask for evidence of self-employed income and trading history.
In this case, speaking to a broker before applying can reduce the risk of approaching a lender whose criteria do not fit. The better route may be a product transfer, a specialist lender or waiting until more income evidence is available. It depends on the facts.
Example 4: Debt consolidation
A borrower has a mortgage and several unsecured debts. They are considering remortgaging to consolidate those debts into the mortgage.
This may reduce monthly outgoings, but it can increase the total amount repaid if the debt is spread over a longer period. It also means the debt becomes secured against the home.
This is not a decision to make based only on monthly payment. It needs careful advice, including the risks and alternatives.

What red flags and trade-offs matter before you apply?
| Situation | Why it matters | What to do before applying |
|---|---|---|
| Your deal ends very soon | You may have limited time to complete a full remortgage | Compare product transfer and full remortgage timescales |
| You have early repayment charges | Switching before the deal ends may be costly | Calculate the charge against any potential benefit |
| Your income has fallen | Affordability may be tighter with a new lender | Check whether a product transfer is available and what evidence is needed |
| You are newly self-employed | Some lenders need a track record of income | Gather tax and accounts evidence before choosing a lender |
| You have recent credit issues | Lender choice may narrow | Avoid speculative applications and check criteria first |
| You want extra borrowing | The lender will assess purpose, affordability and LTV | Compare further advance, remortgage and other options |
| You may move soon | Early repayment charges and portability become important | Check whether fixing again is sensible for your plans |
| Your property is leasehold or has cladding issues | Valuation and legal work may be more complex | Check lease, service charge, ground rent and building safety documents early |
| You are near retirement | Term and income evidence may need closer review | Check lender age limits and retirement income assumptions |

When is mortgage broker advice worth considering?
It is especially worth considering broker advice if:
- your income is variable, self-employed, contractor-based or recently changed
- you have credit issues or recent missed payments
- you want to borrow more
- you are consolidating debt
- your property is leasehold, non-standard, unusual or may have valuation issues
- you are close to retirement or want the mortgage to run into later life
- you are separating from a partner or changing who is named on the mortgage
- you are planning to move soon and need to think about portability
- you are unsure whether to fix, track or stay flexible
- you want to know whether a product transfer or full remortgage is more suitable
public guidance explains that some borrowers shop around themselves, while others use advice. If you use an adviser, check whether they are tied, restricted or able to consider a broad range of lenders, and ask how fees work before you proceed.
James Blackler explains that the value of remortgage advice is often in avoiding the wrong application. A declined or poorly timed application can waste time, create stress and leave you with fewer practical options as your current deal end date approaches.
When we review a remortgage, we usually look at:
- your current mortgage balance, rate and end date
- early repayment charges and exit costs
- property value and estimated LTV
- income, outgoings and credit profile
- future plans, including moving or borrowing more
- product transfer options with your current lender
- wider lender options where appropriate
- total cost, flexibility and suitability
If your situation is simple, we will say so. If your case needs more careful lender matching, we can help you understand which lenders may be more likely to consider the application before you apply.
Speak to a mortgage adviser or make an enquiry if you would like us to look at your circumstances. We cannot promise a lender will approve the case, but we can help you make a more informed decision.

What should you check before choosing a remortgage adviser?
Before deciding who to speak to, ask:
- Is the adviser tied to one lender, restricted to a panel, or able to consider a wider range of lenders?
- What fees apply, when are they payable and are any fees refundable?
- Does the adviser receive commission from the lender?
- Which lender or product types are excluded from their service?
- Do they regularly handle your type of case?
- What happens if the first lender does not accept the application?
- How will the recommendation be explained?
- Will they compare product transfer options as well as full remortgage options where relevant?
A good recommendation should explain why the suggested route fits, what alternatives were considered and what the main risks are.

What should you do before your current deal ends?
Before your current deal ends, gather the facts that change the advice:
- current mortgage balance
- current rate and monthly payment
- deal end date
- early repayment charge
- remaining term
- property value estimate
- income and employment details
- credit commitments
- any recent credit issues
- plans to move, overpay, borrow more or change term
- property issues such as lease length, ground rent, service charge or building safety information
Then compare:
- product transfer with your existing lender
- full remortgage to a new lender
- further advance if you need extra borrowing
- waiting temporarily if switching now is not practical or cost-effective
The strongest next step is not simply asking for the lowest rate. It is asking which route fits your circumstances, what evidence is needed, what could make a lender hesitate and what the fallback plan is.

FAQs
Is it worth getting a mortgage adviser to remortgage?
It can be worth it if your case is not straightforward, you want to borrow more, your income has changed, you have credit issues, your property is unusual, or you want help comparing product transfer and full remortgage options.
If your case is very simple and you are confident comparing total costs yourself, you may decide to deal directly with your lender or shop around without advice. The important point is to understand what is and is not being compared.
What is the best way to remortgage?
The best route depends on your circumstances. For some borrowers, a product transfer with the existing lender is practical and cost-effective. For others, a full remortgage may offer better overall value or flexibility. If you need extra borrowing, the choice may include a further advance or a new remortgage.
The right comparison should include fees, charges, lender criteria, timing and future plans, not just the headline rate.
How early should I start looking at a remortgage?
Many borrowers start around six months before their current deal ends. This gives time to compare options, gather documents, check affordability and deal with valuation or legal work.
Exact timing depends on your current mortgage, your lender and the validity period of any new offer.
Can I remortgage if my income has changed?
Possibly, but lender choice may be more important. A new lender will usually assess your current income and affordability. If you are self-employed, newly employed, on variable income or have recently changed jobs, evidence requirements may differ between lenders.
Your current lender may offer a product transfer with fewer checks, depending on its rules.
Can I remortgage with bad credit?
It may be possible, depending on the type, date and severity of the credit issue, as well as affordability, LTV and the property. Recent missed mortgage payments, defaults or county court judgments can reduce the options available.
Avoid making speculative applications without checking lender criteria first.
Can I remortgage to pay off debt?
Some lenders consider debt consolidation, but it needs careful advice. It may reduce monthly outgoings, but it can increase the total amount repaid if the debt is spread over a longer term. It also turns unsecured debt into borrowing secured against your home.
You should consider the risks and alternatives before proceeding.
Does remortgaging always save money?
No. Remortgaging can reduce costs in some cases, but fees, early repayment charges, higher rates, legal costs or a longer term can change the outcome. Always compare the total cost and not just the monthly payment.
Can I remortgage if I plan to move soon?
You may be able to, but you need to think carefully about early repayment charges and portability. A portable mortgage is not a guarantee that you can move it later, because the lender will usually reassess your income, circumstances and the new property at the time.
Will a remortgage need a valuation?
A full remortgage usually involves some form of valuation, although the type varies by lender and property. A product transfer may not require a new valuation in the same way, but lender rules differ.
The lender’s valuation may not match your estimate.
What happens if my remortgage takes too long?
If your current deal ends before the new mortgage completes, you may move onto your lender’s standard variable rate. Whether that increases your payment depends on your current deal and the lender’s rate at the time.
Starting early and having a fallback plan can reduce this risk.
