A surveyors’ body is calling on estate agents, conveyancers and lenders to advise buyers to get a survey done of any property they are buying.

The Residential Property Surveyors Association (RPSA) has issued the call in the light of announcements by a number of lenders, including Nationwide and Santander, that they may no longer necessarily commission physical mortgage valuation reports.

Instead, lenders will increasingly rely on automated desktop valuations.

A number have been doing so since last autumn, partly in order to overcome severe valuation delays that dogged the market.

RPSA chairman Alan Milstein said: “Buyers have often mistaken the lender’s valuation for a survey of the condition of the property they are about to buy. However, with an increasing reliance on desktop valuations, it means that no one with a trained eye will be visiting the property, let alone assessing its condition.

“This leaves consumers at significant risk.

“It’s more important than ever that lenders, lawyers and estate agents give buyers clear advice about the need for a good-quality survey by a trained, and preferably independent, specialist residential surveyor.

“Ignoring this is ignoring their duty of care to their client.”

According to the main surveyors’ body, the RICS, home buyers routinely spend thousands of pounds on unforeseen repairs when they move in to their new home.

Global property standards director Peter Bolton King said: “Home buyers are often confused about their lender’s valuation. Many still believe their valuation is a survey and is being done for their benefit.

“Increasingly, lenders take a risk-based approach and might well use an automated valuation model which can result in nobody physically visiting the property.

“Our independent research found that on average, home buyers spent £5,750 on unforeseen repairs when they moved in to their new home. The vast majority will have relied on the lender’s valuation only.”
