Quick Answer: Remortgage Valuation in 30 Seconds
Most UK remortgage valuations in 2026 are automated (AVM) — no surveyor visit, completed in 24-48 hours, almost always free. The lender uses Land Registry data and recent comparable sales to value your property remotely. Around 60% of remortgages now complete this way, particularly at 75% LTV and below. For higher-LTV or unusual properties, a drive-by or full physical inspection may be required — typically free with the remortgage deal, occasionally £250-£500. A 'down-valuation' (lower than expected) can push you into a higher LTV band with a more expensive rate; if it happens, you can challenge with comparable evidence, try a different lender with a different valuer, or reduce the loan size. Valuations are for the lender's security — they're not the same as a homebuyer's survey.
The valuation establishes your loan-to-value (LTV) ratio, which is one of the most important factors in mortgage pricing. UK mortgage rates step at 60%, 75%, 80%, 85%, and 90% LTV — each band is typically 0.2-0.5% more expensive than the one below it.
Why Lenders Require a Valuation
When a lender offers you a mortgage, they are taking a risk — if you stop making payments, they need to be confident they can recover the money owed by selling the property. The valuation confirms that the property is worth enough to cover the loan.
The valuation establishes your loan-to-value (LTV) ratio, which is one of the most important factors in mortgage pricing. Lenders offer their best rates at lower LTVs because their risk is lower.
Key LTV thresholds where rates typically improve:
- 90% LTV — Many more deals become available
- 85% LTV — Rates start to improve noticeably
- 80% LTV — Significant improvement in available rates
- 75% LTV — Access to many competitive products
- 60% LTV — Typically the best rates available
The valuation is carried out for the lender's benefit, not yours. It is not the same as a full structural survey and will not identify all potential issues with the property. If you want a detailed assessment of your property's condition, you would need to commission a separate survey.
Types of Remortgage Valuation
There are several types of valuation that lenders use for remortgages:
Desktop valuation (automated valuation model — AVM):
- Carried out remotely using property data, recent comparable sales, and algorithms
- No surveyor visits your property
- Completed quickly — often within 24–48 hours
- Increasingly common for remortgages, especially at lower LTVs
- Often provided free of charge
Drive-by valuation:
- A surveyor visits and inspects the property from the outside only
- They assess the property's exterior condition, location, and comparable sales
- Quicker than a full physical valuation but more thorough than a desktop assessment
Full physical valuation:
- A qualified surveyor visits the property and carries out an internal and external inspection
- They assess the condition, size, layout, and any obvious issues
- This provides the most thorough assessment and is used for higher-risk or unusual properties
- Takes longer to arrange — typically one to two weeks
The type of valuation the lender requires depends on factors such as your LTV, the property type, and the lender's own policies. You generally cannot choose which type is carried out.
