How much can I borrow when remortgaging?

How much you can borrow when remortgaging depends on more than the equity in your home.

Lenders will look at your income, spending, credit history, current mortgage balance and the value of your property. If you want to borrow more, they will also consider why you need the extra money and whether the purpose fits their criteria.

That means there are usually two questions to answer. Can you switch or replace your current mortgage? And, if needed, could you borrow more at the same time?

This guide explains what affects remortgage borrowing, how lenders assess affordability, and why having equity does not always mean you can release the full amount.

How lenders assess your borrowing

When you move to a new lender or ask to borrow more, the lender will look beyond the value of your home. They need to check whether the mortgage is affordable based on your income, outgoings and wider financial position.

Lenders will usually consider:

• Your salary, self-employed income or other regular income
• Loans, credit cards and other credit commitments
• Childcare costs, dependants and household spending
• Your credit file and repayment history
• Your property value, mortgage balance and loan-to-value
• The reason for any extra borrowing

Your circumstances may also have changed since you first took out your mortgage. For example, a pay rise may improve affordability. However, higher household spending, new credit commitments or a change in employment could reduce the amount available.

That is why two homeowners with similar property values and mortgage balances may be offered very different borrowing amounts.

Your equity helps shape how much you could borrow

Your equity is the difference between your property value and the amount you still owe on your mortgage.

For example, if your home is worth £300,000 and your mortgage balance is £180,000, you have £120,000 in equity. That does not mean you can automatically borrow the full £120,000, but it does give the lender a starting point.

Lenders use your property value and mortgage balance to calculate your loan-to-value. This helps decide which remortgage products may be available and how much extra borrowing could be considered.

Illustrative example only. Actual payments and costs depend on your mortgage balance, term, interest rate, fees, lender criteria and circumstances.

Equity is not the same as available borrowing

It is easy to assume that equity works like a cash limit, but lenders do not treat it that way.

Equity shows the difference between your property value and your mortgage balance. However, it does not automatically show how much extra you can borrow. A lender will still decide what they are comfortable offering based on your loan-to-value, income, credit profile, property type and the reason for the extra borrowing.

The purpose of the borrowing can also affect the decision. Some lenders may be more comfortable with extra borrowing for home improvements than for debt consolidation, business purposes or other uses that sit outside their criteria.

So, even if you have a large amount of equity, the amount you can actually borrow may be lower than expected.

Your credit file can affect whether you qualify

Your credit file helps lenders understand how you have managed borrowing in the past.

A strong credit profile may improve your chances of accessing a wider range of remortgage options. However, missed payments, defaults, high credit card balances or recent financial difficulties may reduce the number of lenders available or affect the rate you can secure.

That does not always mean remortgaging is impossible. Some lenders may still consider your application, especially if the issue was historic, low-value or linked to circumstances that have since improved.

Credit issues can make lender choice more important. It is usually better to check your options before applying, rather than making applications that may not fit your profile.

Your monthly repayments need to stay affordable

Increasing your mortgage balance can give you access to funds, but it also means you owe more.

Your monthly payment may rise depending on how much extra you borrow, the interest rate, the mortgage term and whether the additional borrowing is placed on the same deal or a separate product.

The mortgage term can make a big difference. A longer term may reduce the monthly payment, but it can increase the total interest paid over time. A shorter term may reduce long-term interest, but the monthly payment may be higher.

Before borrowing more, it is worth checking both the monthly cost and the total cost. The amount a lender may offer is only one part of the decision. The amount that feels comfortable within your budget matters too.

Debt consolidation can change the risk

Some homeowners ask whether they can remortgage to consolidate debt. This may reduce monthly payments in some cases, especially if higher-interest debts are moved onto a lower mortgage rate.

However, it can also increase the total cost over time. This is because short-term debts may be spread over a much longer mortgage term.

There is also an important risk. If unsecured debts are added to your mortgage, they become secured against your home. If you cannot keep up with the repayments, your home may be at risk.

For that reason, debt consolidation should not be viewed only as a way to reduce monthly payments. The full cost, term, risk and affordability all need to be reviewed carefully.

Your reason for borrowing matters

Lenders often ask why you want to borrow more when remortgaging. The reason can affect whether they are willing to lend and how they assess the application.

For example, borrowing for home improvements may be treated differently from borrowing for debt consolidation, business purposes, gifting money to family or buying another property.

You may also need to provide details about how the money will be used. For larger amounts, the lender may ask for more information before making a decision.

Being clear about your purpose from the start helps avoid delays and makes it easier to identify lenders whose criteria fit your plans.

Remortgaging is not the only way to borrow more

Moving your whole mortgage to a new lender is not always the only way to borrow more. Depending on your current deal, lender and borrowing needs, there may be other routes worth comparing first.

Before choosing a route

The best option is not always the one with the lowest monthly payment. It depends on your early repayment charge, equity, borrowing purpose, affordability and long-term cost.

Muttuo Mortgages can help you compare the routes available before you decide whether remortgaging is the right move.

When borrowing more may be realistic

Getting approved for extra borrowing may be more difficult if your income has reduced, your spending has increased, your credit profile has changed, or your property value has fallen.

It may also be harder if you are close to the maximum loan-to-value a lender will allow, or if the reason for the extra borrowing does not fit the lender’s criteria.

Important: If you are already struggling with monthly payments, increasing your mortgage may not be suitable. A lower monthly payment from consolidating debt can look appealing, but it may increase long-term cost and risk.

Before making a decision, it is important to check the monthly payment, total cost, affordability and whether the borrowing purpose fits the right lender criteria.

When borrowing more may be harder

Borrowing more may be harder if your income has reduced, your spending has increased, your credit profile has changed, or your property value has fallen.

It may also be more difficult if you are close to the maximum loan-to-value a lender will allow, or if the reason for the extra borrowing does not fit the lender’s criteria.

If you are already struggling with monthly payments, increasing your mortgage may not be suitable. A lower monthly payment from consolidating debt can look appealing, but it may increase long-term cost and risk.

In these situations, it is especially important to check affordability carefully before making a decision.

Frequently asked questions on borrowing more

How much can I borrow when remortgaging?

The amount depends on your income, outgoings, property value, mortgage balance, credit profile and lender criteria.

When you remortgage, lenders assess both affordability and security. They look at whether the mortgage is affordable based on your income and spending, and whether the property value supports the amount you want to borrow.

Your equity matters, but it is not the only factor. You may have equity in your home, but still be limited by affordability, credit history or lender rules.

Can I release equity when I remortgage?

You may be able to release equity, but the lender will still check affordability and loan-to-value.

Releasing equity means increasing your mortgage so you can access some of the value built up in your home. This may be used for home improvements, debt consolidation, family support or another purpose.

However, lenders will not usually let you release equity without checking whether the new mortgage is affordable. They will also consider the purpose of the borrowing and the maximum loan-to-value they are comfortable with.

Will I qualify for a remortgage if my credit score has changed?

You may still qualify, but changes to your credit file can affect which lenders and rates are available.

If your credit file has improved since you first took out your mortgage, you may have access to more options. If it has worsened, some lenders may be more cautious.

Missed payments, defaults, high credit use or recent credit applications can all affect lender decisions. This does not always mean you cannot remortgage, but it can make advice more important before applying.

Can I remortgage to consolidate debt?

Possibly, but it needs careful advice because the debt may become secured against your home.

Some homeowners remortgage to consolidate debts into one monthly payment. This can reduce monthly outgoings in some cases, but it may also increase the total interest paid if the debt is spread over a longer term.

It can also turn unsecured debt into borrowing secured against your property. If you cannot keep up with the repayments, your home may be at risk.

Does my property value affect how much I can borrow?

Yes. Your property value affects your loan-to-value, which can influence the deals and borrowing available.

If your property value has increased, or your mortgage balance has reduced, your loan-to-value may have improved. This can sometimes widen your remortgage options.

However, the lender’s valuation may differ from your estimate, and a higher property value does not guarantee extra borrowing. Affordability and lender criteria still matter.

Is a further advance better than remortgaging?

A further advance may be useful if you want to borrow more without leaving your current lender.

A further advance means borrowing extra money from your current lender. It may be worth considering if you are still tied into your current deal and leaving would trigger an early repayment charge.

However, the rate and criteria may differ from your main mortgage. A full remortgage may give you more options, but it may also involve fees and switching costs.

The right route depends on your current deal, borrowing needs and lender options.
