James Greenwood of Stacks Property Search says, “There are many situations where buyers should go beyond the standard survey to protect their investment, and it pays to act early.

“We recommend that everybody gets an RICS Level 3 Building Survey; but most buyers will find that this survey recommends that the buyer commissions a separate drain and electrical inspection - this has become standard. But as the initial survey will generally take around three weeks to arrange and report back, we would recommend that the buyer books the drain and electrical inspection at the same time as the Building Survey to avoid any unnecessary delay.”

Bill Spreckley of Stacks Property Search says, “Legal compliance is critical when it comes to septic tanks. Many older tanks aren't compliant with current environmental regulations, and this is generally flagged during the conveyancing process. If a septic tank is discharging into a waterway it's illegal and must be replaced; the cost can often exceed £15,000. For all properties with a septic tank, an early septic tank survey is advisable, and if there are associated costs with upgrading or replacing it, the cost can be negotiated with the vendor.

“For homes that have a private water supply, testing for pollution and checking for risks such as lead pipework is essential.”

James Greenwood says, “Large trees close to the property, or on neighbouring land close to boundaries should be investigated, for many reasons, but particularly where extensive roots may be threatening the structure of the property. A tree survey, conducted by an arborist, will provide information about tree health and the risks associated with trees, helping buyers make informed decisions about the need for management or removal.”

Sara Ransom says, “Don't skip safety checks on new builds. Even if an EHIC has been conducted, we always recommend a separate gas and electrical inspection, and more often in recent years, an asbestos survey too.”

Amanda Ake says, “Retaining walls play a crucial role in supporting soil and preventing movement. If a buyer has any concerns about the structural integrity of a retaining wall, especially when it's close to the property, we would recommend a survey from a structural engineer.”

When it comes to the RICS Level 3 Building Survey, James Greenwood says, “Make sure your surveyor is RICS-registered, independent, and experienced in the type of property you're buying — especially if it's Listed or unusual. A good surveyor should be independent and focus solely on surveys, not sales.”

He also emphasises the importance of engaging directly with the surveyor. He says, “Surveys can sound scary and overwhelming in writing, but a Level 3 Survey is one of the most useful tools in understanding a property's condition and the scope for any future works. We would recommend buyers attend the survey, and asking questions that arise during the process. When the buyer receives the report, they should read it carefully, then speak to their surveyor to clarify any issues that aren't clear. A follow-up call will always provide essential context and is also a great opportunity to ask any questions related to work you may want to do, for example, establishing where RSJs may be required, or if there are any planning constraints.”
