What Is Remortgaging and How Does It Work?

Remortgaging means changing your mortgage deal on a property you already own.

You might remortgage to get a new interest rate, avoid moving onto your lender’s standard variable rate, borrow more money, change mortgage type, adjust the term, or move to a different lender.

For many homeowners, remortgaging is something to review when a fixed-rate, tracker or discount deal is coming to an end.

It is not the same as moving home.

You are not buying a new property.

You are reviewing or replacing the mortgage on the property you already have.

Handled well, remortgaging can help reduce costs, protect against rate changes or make your mortgage better fit your current circumstances.

Handled badly, it can lead to unnecessary fees, poor timing, declined applications or a more expensive deal.

👉 Check your remortgage options before your current deal ends.

What does remortgaging mean?

Remortgaging usually means replacing your current mortgage with a new mortgage deal.

This can happen in two main ways:

switching to a new deal with your existing lender
moving your mortgage to a different lender

If you stay with your existing lender, this is often called a product transfer.

If you move to a different lender, this is usually called a remortgage.

In everyday language, many people use “remortgage” to describe both.

The aim is usually to avoid sitting on an expensive rate, secure a better deal, or make changes to the mortgage.

Why do people remortgage?

People remortgage for many reasons.

Common reasons include:

their fixed rate is ending
their tracker or discount deal is ending
they want to avoid the standard variable rate
they want a lower interest rate
they want payment certainty
they want to borrow more
they want to reduce monthly payments
they want to shorten the mortgage term
they want to extend the mortgage term
they want to switch from interest-only to repayment
they want to switch from repayment to interest-only
they want to consolidate debts
they want to release equity
they want to rent out the property
they want to remove or add someone to the mortgage
their circumstances have changed

The right reason depends on your situation.

A remortgage should not just be about the headline interest rate.

Fees, timing, flexibility, affordability and future plans matter too.

When should you start thinking about remortgaging?

A good time to start reviewing options is several months before your current mortgage deal ends.

This gives you time to compare rates, check affordability, speak to your lender or broker, and avoid rushing into a poor decision.

If you leave it too late, you may roll onto your lender’s standard variable rate.

That may be more expensive than your previous deal.

Starting early also gives you more time if your case is complex.

For example, you may need more time if:

your income has changed
you are self-employed
you have missed payments
your credit score has changed
you want to borrow more
your property value has changed
you are separating from a partner
you want to rent the property out
your current mortgage has early repayment charges
you are close to retirement

Remortgaging is usually easier when you are prepared.

What happens when your mortgage deal ends?

When your current deal ends, you will usually move onto your lender’s standard variable rate unless you arrange a new deal.

The standard variable rate can be higher than fixed, tracker or discounted deals.

It can also change when the lender changes it.

This may mean your monthly payment increases.

Before the deal ends, you can usually consider:

a new deal with your current lender
a remortgage to a new lender
a fixed rate
a tracker rate
a variable rate
changing the term
borrowing more
making overpayments
doing nothing, if that is genuinely suitable

Doing nothing can be expensive if you drift onto a higher rate by accident.

Remortgage vs product transfer

A remortgage usually means switching to a different lender.

A product transfer usually means switching to a new deal with your current lender.

Both can be useful.

A product transfer may be simpler because:

you stay with the same lender
it may involve less paperwork
it may not need a full legal process
it may be quicker
there may be fewer checks in some cases
it can be useful if your circumstances have worsened

A remortgage to a new lender may be better if:

another lender has a better deal
your current lender is not competitive
you want to borrow more
you want different criteria
your property value has increased
you want a different mortgage type
your current lender cannot help

The best route depends on cost, eligibility and timing.

Is remortgaging the same as getting a new mortgage?

It is similar, but not identical.

When you remortgage to a new lender, the lender will usually assess your application.

They may check:

income
outgoings
debts
credit history
property value
loan-to-value
affordability
employment
mortgage conduct
remaining term
property type

There may also be a valuation and legal work.

If you stay with your current lender through a product transfer, the process may be simpler.

But you should still check whether the new deal is suitable.

How does the remortgage process work?

The process usually looks like this:

Check when your current mortgage deal ends.
Check whether early repayment charges apply.
Review your current balance and property value.
Work out your loan-to-value.
Compare new mortgage deals.
Decide whether to stay with your lender or switch.
Complete affordability and credit checks if needed.
Provide documents.
The lender values the property.
A mortgage offer is issued.
Legal work is completed if switching lender.
The old mortgage is paid off.
The new mortgage starts.

The process can be simple or more involved depending on whether you stay with the same lender or move to a new one.

What is loan-to-value?

Loan-to-value, often called LTV, compares the mortgage balance with the property value.

For example, if your home is worth £300,000 and your mortgage is £210,000, your loan-to-value is 70%.

LTV matters because mortgage rates are often priced in bands.

A lower LTV may give access to better rates.

Your LTV can improve if:

your property value rises
you repay some of the mortgage
you make overpayments
you borrow less compared with the property value

Your LTV can worsen if:

property values fall
you borrow more
the mortgage balance has not reduced much
you switch to interest-only and do not repay capital

A remortgage review should include an updated property value estimate.

What documents do you need to remortgage?

If you are switching to a new lender, you may need documents such as:

payslips
bank statements
proof of ID
proof of address
mortgage statement
details of existing mortgage
proof of bonus or commission
self-employed accounts
SA302s or tax year overviews
proof of pension income
details of debts
property information
buildings insurance details

If you are doing a product transfer with your current lender, fewer documents may be needed.

But if you are borrowing more or changing the mortgage significantly, the lender may ask for more evidence.

For related guidance, read can you get a mortgage without proof of income?

Does remortgaging involve affordability checks?

Often, yes.

If you move to a new lender, you should expect affordability checks.

The lender will want to know whether the mortgage is affordable based on your income, outgoings and commitments.

They may consider:

salary
self-employed income
bonus
commission
overtime
pension income
benefits
childcare costs
loans
credit cards
car finance
dependants
household bills
mortgage term
interest rate
credit commitments

If you stay with your current lender and do not borrow more, the process may be simpler in some cases.

But affordability still matters, especially if you are changing the mortgage or borrowing more.

For more detail, read how mortgage lenders assess affordability.

Can you remortgage early?

Yes, you may be able to remortgage before your current deal ends.

But you need to check whether early repayment charges apply.

Early repayment charges can be expensive.

They may reduce or wipe out the benefit of switching early.

You should compare:

the saving from the new deal
the early repayment charge
exit fees
arrangement fees
valuation fees
legal fees
timing
whether rates may change
whether your current lender can offer a product transfer

Sometimes switching early makes sense.

Sometimes waiting is better.

What are early repayment charges?

An early repayment charge is a fee for leaving a mortgage deal early or repaying more than allowed during a fixed, tracker or discount period.

Not every mortgage has the same rules.

Some charges reduce over time.

Others stay fixed during the deal period.

Before remortgaging, check your mortgage offer or annual statement to see:

whether an early repayment charge applies
when it ends
how much it is
whether any exit fee applies
whether overpayments are allowed
whether switching product avoids or reduces the charge

This is one reason timing matters.

Can you remortgage to borrow more?

Yes, some homeowners remortgage to borrow more.

This is sometimes called additional borrowing or capital raising.

People may borrow more for:

home improvements
debt consolidation
buying out a partner
helping family
investment property deposit
paying off a Help to Buy equity loan
major repairs
other large expenses

Borrowing more is not automatic.

The lender will check affordability, loan-to-value, credit history and the reason for borrowing.

You should think carefully before increasing a mortgage.

A mortgage is secured against your home, so borrowing more can increase long-term risk.

Can you remortgage to consolidate debt?

You may be able to remortgage to consolidate debts, but this needs caution.

Debt consolidation can reduce monthly payments, but it may increase the total amount repaid if unsecured debts are spread over a longer mortgage term.

It also turns unsecured borrowing into debt secured against your home.

That can increase the risk if payments are missed.

Before consolidating debt into a mortgage, consider:

total interest cost
mortgage term
fees
affordability
whether spending habits have changed
whether debts may build again
impact on loan-to-value
advice from a qualified adviser

Lower monthly payments are not the same as lower total cost.

Can you remortgage with bad credit?

It may be possible to remortgage with bad credit, but lender choice can be reduced.

Bad credit may include:

missed payments
defaults
CCJs
debt management
arrears
bankruptcy history
high credit card balances
heavy overdraft use

A product transfer with your current lender may sometimes be simpler than moving to a new lender.

But if you need to switch lender, the credit history will matter.

For more detail, read can you get a mortgage with bad credit?

Can you remortgage after missing mortgage payments?

Possibly, but it can be harder.

Recent missed mortgage payments are taken seriously.

A lender may ask:

how many payments were missed
when they happened
why they happened
whether arrears are cleared
whether payments are now up to date
whether the issue is resolved
whether affordability is now stable

If you are currently in arrears, do not apply randomly.

Speak to your lender, a broker or a debt adviser before making decisions.

Can you remortgage if you are self-employed?

Yes, self-employed borrowers can remortgage.

The lender may ask for evidence such as:

accounts
SA302 tax calculations
tax year overviews
business bank statements
accountant details
salary and dividends
net profit
company profit

Different lenders assess self-employed income differently.

If your income has changed since your last mortgage, lender choice becomes important.

Can you remortgage to rent out your home?

Sometimes.

If you want to rent out a home currently on a residential mortgage, you may need either consent to let or a buy-to-let remortgage.

Consent to let may be suitable for temporary renting.

A buy-to-let remortgage may be needed if the property is becoming a longer-term rental.

This can affect rates, affordability, rental income checks, tax and insurance.

For more detail, read can you rent out your home with a residential mortgage?

Can you remortgage over 50?

Yes, many people remortgage over 50.

But the lender may look closely at the mortgage term, retirement age and income into retirement.

They may consider:

employment income
pension income
investment income
retirement age
mortgage term
repayment method
affordability beyond retirement
property value
existing balance

For more detail, read can you remortgage over 50?.

Can you remortgage to remove someone from the mortgage?

Sometimes.

This may happen after separation, divorce or a change in ownership.

The remaining borrower usually needs to prove they can afford the mortgage alone.

There may also be legal work, ownership changes and affordability checks.

If one person is being removed, the lender must agree.

For related guidance, read what happens if you separate during a mortgage application?.

Fixed, tracker or variable when remortgaging?

When remortgaging, you may need to choose between a fixed, tracker or variable rate.

A fixed rate gives payment certainty for a set period.

A tracker rate usually moves in line with a benchmark rate.

A standard variable rate can change at the lender’s discretion.

The right choice depends on:

your budget
risk tolerance
rate expectations
need for flexibility
early repayment charges
moving plans
overpayment plans
product fees
offer timing

For more detail, read tracker vs fixed-rate mortgages: which is better?

How long does remortgaging take?

Timescales vary.

A simple product transfer with your current lender may be quick.

A remortgage to a new lender may take longer because it can involve affordability checks, valuation, underwriting and legal work.

Delays can happen because of:

missing documents
valuation issues
legal work
lender workload
credit issues
income complexity
early repayment charge timing
property title issues

It is sensible to start early rather than wait until the last minute.

For a similar process breakdown, read how long does a mortgage application take?

Does remortgaging need a valuation?

If you switch to a new lender, the lender will usually want to value the property.

This may be:

automated valuation
desktop valuation
physical valuation

A higher property value may improve loan-to-value.

A lower valuation may reduce available options or affect the rate.

For more detail, read mortgage valuation explained.

Does remortgaging need a solicitor?

If you move to a new lender, legal work is usually needed.

This is because the old lender’s charge must be removed and the new lender’s charge registered against the property.

Some remortgage products include free or assisted legal work.

Others may require you to arrange a solicitor.

A product transfer with your existing lender usually needs less legal work, because the lender is not changing.

What fees should you check?

Before remortgaging, check all costs.

These may include:

product fee
arrangement fee
valuation fee
legal fee
exit fee
early repayment charge
broker fee
higher lending charge in some cases
telegraphic transfer fee
insurance changes
advice fees

A lower interest rate is not always cheaper overall if the fees are high.

Compare the total cost over the deal period, not just the monthly payment.

Should you use a broker to remortgage?

You do not have to use a broker.

Some people remortgage directly with their current lender or another lender.

A broker can be useful if:

you want to compare lenders
your income has changed
you are self-employed
you have credit issues
you want to borrow more
you are near retirement
you want to rent out the property
affordability is tight
you need help comparing fees and rates
you have missed payments
your property is unusual

A broker can help compare the product transfer option with remortgaging to a new lender.

For more detail, read how getting a mortgage without a broker works.

When might you not remortgage?

Remortgaging may not be the best move if:

early repayment charges are too high
your current lender offers a good product transfer
your credit position has worsened
your income has fallen
you are about to move home
the new fees outweigh the saving
your loan-to-value has worsened
you need debt advice first
you are in serious arrears
you cannot pass affordability checks

Sometimes the best option is staying with your current lender.

Sometimes the best option is waiting.

Sometimes the best option is getting advice before doing anything.

Common remortgage mistakes

Avoid:

waiting until the current deal has already ended
focusing only on the lowest interest rate
ignoring fees
missing early repayment charges
assuming your current lender is cheapest
assuming a new lender will accept you
borrowing more without checking long-term cost
consolidating debt without advice
applying randomly after credit problems
forgetting legal or valuation timescales
ignoring loan-to-value
choosing the wrong fixed or tracker period

A remortgage should be planned, not rushed.

Realistic example

A homeowner has six months left on a five-year fixed rate.

Their lender writes to them with a product transfer option.

A broker also checks the wider market and finds another lender with a lower rate, but the new lender has a product fee and requires legal work.

The homeowner compares:

current lender product transfer
new lender remortgage
monthly payment
total fees
early repayment charge timing
loan-to-value
flexibility
future plans

The cheapest headline rate is not automatically the best option.

The best deal is the one that fits the full situation.
