What Do Lenders Look For When Remortgaging?

Your Credit History and Credit Score

One of the first things a lender checks when you apply for a remortgage is your credit history. They access your credit file through one or more of the three main UK credit reference agencies — Experian, Equifax, and TransUnion — to build a picture of your borrowing behaviour and financial reliability.

What lenders look for on your credit file:

• Payment history — Have you made all your credit payments on time? Late or missed payments on mortgages, loans, credit cards, or even utility bills can raise concerns. More recent issues carry greater weight than older ones.
• Outstanding debts — The total amount you owe across all credit commitments. High levels of existing debt can affect both your affordability assessment and the lender's confidence in your financial management.
• Credit utilisation — How much of your available credit you are using. Using more than 50% of your credit card limits can signal financial stress to lenders, even if you make payments on time.
• County Court Judgments (CCJs) — Any CCJs registered against you remain on your credit file for six years and can significantly impact your application with mainstream lenders.
• Defaults — A formal default on a credit agreement is a serious negative mark. Like CCJs, defaults remain visible for six years.
• Insolvency events — Bankruptcy, Individual Voluntary Arrangements (IVAs), and Debt Relief Orders are among the most severe adverse credit markers and will restrict your options significantly.
• Electoral roll registration — Being registered on the electoral roll at your current address helps verify your identity and address, which supports your credit profile.
• Recent credit applications — Multiple credit applications in a short period can suggest financial difficulty and may lower your credit score.

Before applying for a remortgage, it is advisable to check your credit report using a free service. This allows you to identify and correct any errors, understand how lenders will view your profile, and take steps to improve your score if needed. Even small improvements — such as paying down credit card balances or registering on the electoral roll — can make a difference.

Income, Employment, and Affordability

Lenders need to verify that you earn enough to comfortably afford the mortgage payments you are applying for, both now and in the future. The affordability assessment is one of the most detailed parts of the application process.

Employment status:

Lenders want to see stable, reliable employment. The specifics depend on your situation:

• Permanent employees — Generally the simplest to assess. Lenders want to see that you have passed any probationary period and have a stable employment history.
• Contract workers — Lenders may require evidence of contract renewals or a track record of continuous contract work in the same field. Some lenders treat contractors more favourably than others.
• Self-employed — You will need two to three years of trading history, supported by SA302 forms or certified accounts. Lenders assess your average or most recent annual income.
• Agency workers — Accepted by some lenders, but you may need to demonstrate a consistent income pattern over 12 months or more.
• Recently changed jobs — Lenders prefer to see that you have passed your probationary period. If you are still in probation, some lenders will consider your application, but options may be more limited.

Income verification:

Your income will be verified through documentation — payslips, P60s, tax returns, and bank statements. Lenders cross-reference these documents against the figures you provide on your application. Any discrepancies will be queried and may delay the process.

Affordability calculation:

Beyond verifying your income, lenders carry out a detailed affordability assessment. They analyse your income after tax, subtract all committed expenditure and essential living costs, and determine whether you have sufficient disposable income to cover the mortgage payments — including a stress test at a higher interest rate.

The affordability assessment is the area where most remortgage applications encounter difficulties. Preparing thoroughly by gathering accurate documentation and understanding how your income and outgoings will be assessed gives you the best chance of approval.

Property Value and Condition

Your property is the lender's security for the mortgage, so they need to be satisfied that it is worth enough to support the loan and that it is in acceptable condition. The lender arranges their own valuation as part of the remortgage process.

Property valuation:

The lender's valuation determines the loan-to-value (LTV) ratio and therefore affects the rates available to you and the maximum you can borrow. Valuations can take several forms:

• Desktop valuation — A remote assessment using property data, algorithms, and comparable sales information. This is the fastest and most common type for standard remortgages.
• Drive-by valuation — A valuer inspects the exterior of the property without entering. This provides a basic confirmation of the property's existence and condition.
• Full physical valuation — A surveyor visits the property and carries out an internal and external inspection. This is more common for higher-value properties, non-standard construction, or where the lender has specific concerns.

What can affect the valuation:

• Property condition — Significant disrepair, structural issues, damp, subsidence, or Japanese knotweed can reduce the valuation or cause the lender to decline the property as security.
• Non-standard construction — Properties built using non-traditional methods (such as concrete panel, steel frame, or timber frame) may be valued differently and some lenders may not lend against them.
• Lease length — For leasehold properties, a short remaining lease (under 80 years) can significantly reduce the valuation and limit your mortgage options.
• Location factors — Proximity to commercial properties, flood zones, mining areas, or other environmental risks can affect the valuation.
• Alterations without consent — Extensions or structural changes made without proper planning permission or building regulations approval can create valuation and legal issues.

If the lender's valuation comes in lower than expected, it can increase your LTV ratio, potentially pushing you into a higher rate band or reducing the amount you can borrow. In some cases, a low valuation can prevent the remortgage from proceeding at all. You may have the option to challenge the valuation or seek a second opinion, though this depends on the lender's policy.

Your Existing Mortgage and Payment History

Lenders pay close attention to how you have managed your existing mortgage. Your mortgage payment history is one of the strongest indicators of how you are likely to behave as a borrower going forward.

What lenders check:

• Payment track record — Have you made all your mortgage payments on time? Even one missed payment in the last 12 months can be a red flag for many mainstream lenders. Multiple arrears or a history of late payments will significantly reduce your options.
• Current mortgage balance — Your outstanding balance determines your LTV ratio, which affects the rates and products available to you.
• Type of current mortgage — Whether you are on a fixed rate, tracker, or SVR tells the lender about your current payment level and whether you are facing a payment increase.
• Early repayment charges — While this does not affect the lender's decision, it is relevant to the timing and cost-effectiveness of your remortgage.
• Mortgage conduct — Beyond payments, lenders may look at whether you have previously been subject to forbearance arrangements, payment holidays, or other concessions from your current lender.

The importance of a clean payment record:

A clean mortgage payment history over the last 12 to 24 months is one of the strongest positive factors in a remortgage application. It demonstrates financial responsibility and gives the new lender confidence that you will maintain payments on the new mortgage.

If you have any missed payments or arrears on your mortgage record, it does not necessarily prevent you from remortgaging, but it does reduce your options. Specialist lenders cater to borrowers with imperfect payment histories, though their rates tend to be higher than mainstream products. A mortgage broker can help you find the most suitable lender for your circumstances.

It is worth noting that your existing lender may be more lenient about past payment issues when offering you a product transfer. Since they already hold your mortgage and can see your overall account conduct, they may take a more holistic view than a new lender who sees only the credit file entry.

Your Deposit (Equity) and Loan-to-Value Ratio

Unlike a purchase mortgage, you do not need a cash deposit to remortgage. Instead, lenders look at the equity you have in your property — the difference between your property's value and your outstanding mortgage balance.

How equity affects your remortgage:

• LTV determines your rate — Lenders price mortgages in LTV bands. The more equity you have, the lower your LTV, and the better rates available to you. The best rates are typically at 60% LTV or below, with rates increasing at each step: 65%, 70%, 75%, 80%, 85%, and 90%.
• Minimum equity requirements — Most remortgage lenders require you to retain at least 10% to 20% equity in your property. Some specialist lenders accept higher LTV ratios, but rates are significantly more expensive.
• Equity for additional borrowing — If you want to release equity (borrow more than your current mortgage balance), you need sufficient equity above the lender's minimum retention level.

How equity builds:

Your equity increases through two mechanisms: paying down your mortgage balance over time, and any increase in your property's value. Both factors work in your favour when remortgaging.

• If you bought your home at £250,000 with a £200,000 mortgage (80% LTV) and have since paid the balance down to £180,000 while the property has increased in value to £280,000, your LTV has improved from 80% to approximately 64%. This puts you in a significantly better position for competitive rates.

Conversely, if property values have fallen or you have paid down very little of your capital (for example, on an interest-only mortgage), your LTV may be higher than expected, limiting your options.

Understanding your equity position before you apply helps you target the right deals and set realistic expectations about the rates and products available to you.

How to Strengthen Your Remortgage Application

Now that you understand what lenders look for, here are practical steps to present the strongest possible application:

Before you apply:

• Check your credit report — Review your file with all three agencies and correct any errors. Register on the electoral roll if you are not already. Pay down credit card balances to below 50% of each card's limit.
• Reduce outstanding debts — Pay off or pay down loans, credit cards, and other commitments where possible. This improves both your credit profile and your affordability assessment.
• Gather your documentation — Assemble all the documents you will need: payslips, P60, bank statements, current mortgage statement, and proof of identity. Having everything ready speeds up the process.
• Stabilise your employment — If possible, wait until you have passed any probationary period before applying. Avoid changing jobs during the remortgage process.
• Address property issues — If you know of any property problems that could affect the valuation (such as needed repairs or unresolved planning issues), consider addressing them before applying.

During the application:

• Be accurate and consistent — Ensure all information on your application matches your supporting documents. Discrepancies trigger queries and delays.
• Declare everything — Do not omit any debts, financial commitments, or adverse credit history. Lenders will discover them through your credit file, and undisclosed items raise concerns about honesty.
• Respond promptly — When the lender or solicitor requests additional information, respond as quickly as possible. Delays in providing information can hold up your entire application.
• Use a broker — An FCA-regulated mortgage broker can assess your circumstances, recommend suitable lenders, and present your application in the best possible way. They know what each lender is looking for and can anticipate potential issues.

Taking these steps does not guarantee approval, but it significantly improves your chances and helps the process run as smoothly as possible. A well-prepared application is processed faster, encounters fewer queries, and is more likely to result in a favourable outcome.
