More than a million homeowners in the UK are planning to remortgage in 2026. If you are one of them, you will need to go through a remortgage valuation of your property. This often stresses out some homeowners, but working with an experienced Mortgage Broker Richmond can help you stay informed and prepared every step of the way.
A remortgage valuation is nothing but your mortgage lender’s way of checking if your property will cover their losses if you default on your payments. It assures them that your property has the value you claim it has.
You shouldn’t take valuation lightly. About 1 in every 5 remortgages end up with down-valuations (the estimate not being accurate).
This guide will help you understand remortgage valuation.
What is a remortgage valuation?
Remortgage valuation is the assessment of your property’s current market value while remortgaging it. It is conducted for the lender’s benefit, helping them confirm your claim about your property’s value at the time of remortgaging. The valuation confirms whether the property gives the lender enough security for their loan.
You should also know that a remortgage valuation is not a condition survey. It will not highlight and flag problems like boiler issues, maintenance issues, and more unless they are too serious to ignore.
Why do you need a remortgage valuation?
Remortgage valuation gives you your loan-to-value ratio. It is the ratio between your property’s value and your mortgage amount.
It is this number that determines your mortgage interest rate when you remortgage.
Mortgage rates in the UK are tiered in 5% LTV bands (60%,75%, 80%, 85%, and so on). A low LTV percentage means low risk for the lender, encouraging them to give you better loan terms. Understanding your LTV is also a key part of building smart investment strategies around your property portfolio.
If your property’s value has increased at the time of remortgaging, your LTV will decrease. After valuation, your lender is likely to give you a better mortgage rate for the same property.
Types of remortgage valuations
Different lenders use different remortgage valuation procedures.
Automated Valuation Model (AVM)
AVM is a hassle-free remote valuation process. An algorithm analyses recent local sales data, historical pricing, and Land Registry records to estimate your property’s value in no time. It is usually completed in 24 hours.
Drive-by or external valuation
This is the traditional process of a surveyor visiting your house. They assess the exterior and the neighbourhood for valuation without coming in.
Physical or internal valuation
Internal valuation involves the surveyor entering your home and checking factors like size, layout, and general condition.
Do you always need a remortgage valuation?
A remortgage valuation is not always necessary. The process is generally skipped when homeowners decide to stay with the same lender and just switch mortgage deals. The lenders will simply update your property’s value based on local trends using AVMs.
What happens during a physical remortgage valuation?
Most physical valuation visits are quick, and there is no need to panic. Know that the surveyors have no interest in your lifestyle and how dirty your dishes are! They are only interested in the building.
Here is what they will check:
- Overall square footage
- Number of rooms
- Structural updates like loft conversions, extensions, etc.
- Presence of hazardous materials or invasive plants
- Comparable sales in your neighbourhood
There are also a few things a surveyor already knows before visiting your house. They have already looked into your EPC data, sold prices, and the Land Registry. They will already have a benchmark price in their mind. The visit just confirms their estimate.
What to do if the valuation is lower than expected?
Such cases lead to you being downvalued. If your property’s value is less than claimed (or has reduced at the time of remortgaging), your LTV will increase. This will directly impact your new mortgage rate and loan terms.
However, if you are confident, you can challenge a down-valuation with some lenders.
Here is what you can do:
Gather evidence
Gather data on at least three comparable properties sold (not just listed) in the last 3 to 6 months.
File the appeal form
Go through the formal appeal process based on the lender you are working with.
Remortgage valuation vs. other valuations
Homeowners often assume that a remortgage valuation can be used for various other purposes. However, this is not the case.
The table below compares remortgage valuation with other related property valuations:
| Feature | Remortgage Valuation | Building Survey | Probate Valuation |
| Purpose | Lender security | Buyer’s peace of mind | Inheritance Tax (HMRC) |
| Cost | Often Free / Low | £500 – £1,500 | £250 – £600 |
| Focus | Market Value | Structural Integrity | Open Market Value at death |
Frequently Asked Questions
How long does a remortgage valuation take?
AVM can get the job done in 1 to 3 days. A physical survey can take around a week.
What if my house is worth more when I remortgage?
In such a situation, your LTV will drop, making it safer for a lender to give you a new loan. You are likely to get a new mortgage deal at a lower interest rate and better loan terms.
Can I remortgage without a valuation?
You can do so only with the existing lender (as a product transfer). New lenders will always ask for some kind of valuation (at least through AVMs).
Working with a mortgage expert can help while remortgaging your home. Always look for a fee-free mortgage broker for your remortgages, which can help you to save money.
