Yes, when you remortgage, your house is usually revalued in some way. That does not always mean someone will visit your home. Depending on the lender, your loan-to-value, the property and the application, the valuation may be automated, desktop-based, external, or carried out in person.
The lender is checking two things: value and risk. They want to know what your home is worth before deciding how much they may be prepared to lend against it. This valuation helps shape your loan-to-value, often called LTV, which can affect the mortgage products available to you.
If you are moving to a new lender, borrowing more, or your circumstances have changed, the valuation may carry more weight. If you are staying with your current lender and simply switching products, the process may be lighter.
Why lenders revalue your house when you remortgage
When you apply for a remortgage, the lender looks at whether the mortgage appears affordable and whether the property is suitable security for the loan.
Your property value matters because it helps the lender calculate your LTV. MoneyHelper’s remortgaging guidance explains that if property values fall, your LTV may rise, which can affect your remortgage options.
| Estimated property value | Mortgage balance | Approximate LTV |
| £300,000 | £240,000 | 80% |
| £300,000 | £210,000 | 70% |
| £300,000 | £180,000 | 60% |
A lower LTV may improve the range of options available, although this depends on lender criteria, income, outgoings, credit profile, property type and the products available at the time.
Is a remortgage valuation the same as a survey?
No. A remortgage valuation is not the same as a property survey.
A valuation is mainly for the lender’s benefit. Lender valuation guidance explains that mortgage valuations and customer surveys are different, even when both relate to the same property.
A survey is more detailed. It is designed to help you understand the condition of the property, including potential defects, damp, roof issues, structural concerns or repair needs.
| Feature | Remortgage valuation | Property survey |
| Main purpose | Helps the lender assess value and security | Helps you understand the property condition |
| Main user | The lender | The homeowner or buyer |
| Detail level | Usually limited | More detailed |
| Repair advice | Not usually | Often, depending on the survey type |
If you are remortgaging a home you already own, you may not be required by the lender to arrange a full survey. However, if you are concerned about the property’s condition, a separate professional survey may be worth considering.
How your house may be valued during a remortgage
The lender chooses the valuation method. This can depend on the LTV, loan amount, property type, available market data and the lender’s criteria.
Automated valuation
An automated valuation model uses data such as recent property sales, market trends, property type and local information to estimate value. This is often used where the case appears straightforward, and the lender has enough confidence in the data.
Desktop valuation
A desktop valuation is completed remotely. A valuer reviews available information and comparable sales without visiting your home.
Drive-by valuation
A drive-by valuation involves an external look at the property. The valuer does not usually inspect the inside, but they may check the exterior and general setting.
Physical valuation
A physical valuation involves a visit to the property. This may be more likely if the property is unusual, the borrowing is higher, the LTV is tight, or the lender needs a closer view before deciding.
Even with a visit, it is still a valuation for mortgage purposes, not a full condition survey.
What affects the valuation when you remortgage?
Several factors can affect the figure the lender uses, including:
- Recent sold prices for similar homes
- Property type, size and layout
- General condition and presentation
- Obvious maintenance or structural concerns
- Lease length, where relevant
- Construction type
- Local market demand
- Improvements made since purchase
- Whether the property is standard or unusual
Estate agent estimates and online valuations can be useful for a rough sense check, but the lender will rely on its own valuation process.
Can home improvements increase the remortgage valuation?
Home improvements may support a higher valuation, but there is no guarantee. A well-planned extension, loft conversion, improved layout or essential repair work may make the property more attractive to buyers and valuers. Cosmetic upgrades can help presentation, but lenders tend to focus more on comparable sold prices and market evidence than personal taste.
If you have made major changes, it can help to keep documents ready, such as:
- Planning documents, where relevant
- Building regulation certificates
- Completion certificates
- Invoices for significant works
- Guarantees or warranties
- Evidence of added floor space
If you aim to borrow more after improvements, our guide on releasing equity when you remortgage explains how lenders may consider equity, renovations, and affordability together.
What happens if your house is valued lower than expected?
A lower valuation can affect your remortgage options. This is often called a down valuation.
For example, you may believe your home is worth £320,000, but the lender values it at £300,000. If your mortgage balance is £240,000, your expected LTV would have been 75%. Based on the lower valuation, it becomes 80%.
That difference may matter if the products available change at certain LTV bands.
If this happens, your options may include:
- Choosing a different mortgage product
- Reducing the amount you want to borrow
- Using savings to lower the LTV, if this is affordable and suitable for your circumstances
- Asking whether the valuation can be reviewed
- Considering another lender
- Staying with your current lender through a product transfer
- Waiting until your property value, mortgage balance or wider financial position changes
The most suitable route will depend on your circumstances and lender criteria, including your current deal, early repayment charges, income, credit position and borrowing goals.
Will your current lender revalue your house if you switch deals?
If you stay with your current lender and switch to a new deal, often called a product transfer, the valuation process may be simpler than moving to a new lender.
Your current lender may use an indexed valuation or internal estimate. However, if you want to borrow more, change the mortgage term, or adjust the loan significantly, further checks may still be needed.
A product transfer can sometimes be quicker, but it is not automatically the best option. It is still sensible to compare it with the wider market, especially if your property value, borrowing needs or financial circumstances have changed.
This is where speaking to us can be useful. Through our mortgages and remortgages service, we can discuss your current deal, estimated property value, borrowing needs and wider circumstances before helping you understand which remortgage route may be suitable.
Whether you are switching deals, moving to a new lender, borrowing more or reviewing your monthly payments, we can help you understand the options that may be available.
Can credit history affect a remortgage?
Your credit history does not usually change the property value itself, but it can affect how many lenders are available to you and what terms they may consider.
For example, if your LTV is higher than expected and your credit file also includes missed payments, defaults or other issues, your options may become more limited. That does not always mean remortgaging is impossible, but it does mean the case needs careful handling.
The responsible lending rules in the FCA Handbook set out how lenders should assess affordability for regulated mortgage contracts. Put simply, lenders are not just checking the house. They are checking whether the borrowing makes sense.
If credit issues are part of the picture, our guide on whether you can remortgage with bad credit history may help you understand what lenders tend to look at.
How long does a remortgage valuation take?
The valuation itself can be quick, especially if the lender uses an automated or desktop method. A physical valuation may take longer because it depends on access, valuer availability and lender processing times.
The full timeline can also be affected by legal work, affordability checks, underwriting queries and whether anything unusual comes up. If timing matters, our guide on how long a remortgage takes breaks down the stages in more detail.
How to prepare before a remortgage valuation
You do not need to redecorate before a valuation, but it helps to have key information ready.
Step 1: Check your current mortgage balance
Start with what you still owe. This gives you the first part of your estimated LTV.
Step 2: Estimate your property value realistically
Look at recently sold prices rather than only asking prices. Asking prices can be hopeful. Sold prices are usually more useful.
Step 3: Gather paperwork for major improvements
If you have extended, converted or carried out structural work, keep certificates and evidence ready.
Step 4: Review your current mortgage terms
Check when your deal ends, whether early repayment charges apply, and whether any exit fees are involved.
What to remember about house revaluation when you remortgage
When you remortgage, your house is usually revalued, but the method can vary. The lender may use an automated valuation, desktop check, drive-by assessment or physical inspection.
The valuation helps the lender work out your LTV and decide whether the property is suitable security for the loan. It can affect the products available, especially if your home is valued higher or lower than expected.
At Finance 4 Homes, we can help you consider factors such as property value, affordability, credit history, timing and lender criteria, rather than looking only at the interest rate. You can speak to us if you would like to understand the remortgage options that may be available.
Think carefully about securing other debts against your home. Your home may be repossessed if you do not keep up repayments on your mortgage or other debt secured on it.
You may be charged a fee for mortgage advice, which could be up to 1% of the loan. The precise amount will depend on your circumstances, but we estimate it to be 0.75% of the loan amount. These are illustrative estimates. Your actual fee may differ depending on your circumstances, complexity, credit history and lender requirements.
Not all applicants will qualify. Product availability, interest rates and loan amounts depend on individual circumstances and lender criteria.
If you are experiencing financial difficulty, you can get free and impartial debt advice from organisations such as MoneyHelper, StepChange, or Citizens Advice.
