Quick summary

In the UK, house valuations for remortgages typically take a few days to a week, with costs often up to around £150 to £300 depending on the property size and type. They can be desktop or drive-by, and are usually brief. Remember, a valuation is just an estimate of your home's current market value for the lender’s benefit.

If you are thinking about remortgaging, it is always a good idea to get your house valued first. A remortgage valuation gives you an indication of your home’s current market value, and this up-to-date valuation will mean that your new mortgage will reflect what your home is worth and secure you the right deal for your situation.

How will your house be valued for a remortgage?

Normally the lender will instruct a surveyor to value your home. There are a couple of different ways that they might value your property:

  • Desktop valuation is a computer-automated valuation done using recent comparable sales, property data and property listings. It is what it says on the tin: the valuation of the property can be estimated from a desk, without needing a physical visit to the property.

  • Drive-by valuation is where the surveyor will value the

  • property from the outside of the house. The surveyor will usually do a basic inspection of the outside of the house, looking for major problems on the roof or walls, which could affect the value of the property.
