How to Dispute a Down-Valuation After a Survey

Buying or remortgaging a home is stressful enough without being told your property isn’t worth what you expected. A down-valuation by a surveyor can derail your plans, slow progress, or even collapse the deal. 

But you don’t have to accept it blindly. If the figure seems unfair, there are steps you can take to challenge it and possibly turn things around. Read on to find out exactly how you can handle a down-valuation with confidence.

Understand Why the Property Was Down-Valued

Start by carefully reviewing the surveyor’s report. Look for specific reasons cited for the lower value. It might be due to the property’s condition, the local market, or unsuitable comparisons with cheaper homes nearby. If you spot inaccuracies or outdated information, note them down. Be thorough, as this will form the basis of your argument.

Use a Home Survey to Back Up Your Case

If you already paid for a home survey, go back through its findings. Has the surveyor missed important upgrades? Were structural issues misunderstood or overstated? Sometimes, a simple oversight in the report can lead to a poor valuation. Ensure your survey evidence is clear and factually correct before moving forward.

Build a Strong Case with Comparables

Compile recent sales data from similar properties in the area. Focus on homes with the same size, layout, and condition that have sold within the past three to six months. The goal is to show that your property’s value is in line with the current market, not below it.

Ask for a Reassessment from Your Lender

With all your evidence ready, approach your mortgage adviser or lender to request a valuation review. Be polite, direct, and present your case clearly. Some lenders allow a second valuation, but you may need to cover the cost. Make sure to ask what options are available under their policy.

Renegotiate or Explore Other Options

If you’re buying, share the valuation with the seller and try to renegotiate the price. Sellers often prefer adjusting the figure rather than losing the sale entirely. If you’re remortgaging, consider switching lenders if the current one won’t reassess.

Consider a Complaint as a Final Step

If the valuation includes clear errors or the surveyor acted unprofessionally, you have the right to file a complaint. Start with the RICS-registered firm that issued the report. If unresolved, escalate to The Property Ombudsman for further review. Keep copies of all documents and communications.

Your Next Move

A down-valuation is frustrating, but not the end of the road. If you stay calm, gather strong evidence, and act quickly, you stand a good chance of getting a fair result. A well-reasoned dispute can save your sale, protect your investment, and keep your property plans on track.
