Choosing a Surveyor in London: Types of Survey, RICS Accreditation and What Each Covers

When you apply for a mortgage, the lender commissions a valuation of the property. This valuation confirms that the property exists, is mortgageable, and is worth at least the amount being lent. It is primarily for the lender's benefit and provides almost no useful information about the condition of the property. It is not a survey.

Many buyers assume that a satisfactory mortgage valuation means the property has been inspected and found to be in acceptable condition. This is a common and potentially costly misconception. Valuers visit properties for minutes rather than hours and are not commissioned to report on condition in any detail.

The Royal Institution of Chartered Surveyors (RICS) has standardised residential surveys into three levels:

RICS Level 1 (Condition Report): a basic overview of the condition of a property, using a simple traffic light rating system (1, 2, 3) for different elements. No legal or environmental issues covered. Suitable only for newer, conventional properties in good condition where significant issues are unlikely. Rarely appropriate for London's older housing stock.

RICS Level 2 (HomeBuyer Survey, now called Homebuyer Report or Survey Report): the most commonly commissioned survey for standard residential properties. Provides a visual inspection of accessible areas, identifies visible defects, and gives condition ratings with explanations. Includes advice on what requires urgent attention and what should be investigated further. Does not include maintenance cost estimates or advice on how to carry out repairs. A Level 2 survey is appropriate for conventional London properties (post-1850 construction, broadly standard construction, no obvious major defects).

RICS Level 3 (Building Survey, previously called Full Structural Survey): the most comprehensive and detailed RICS survey. Includes an in-depth inspection of all visible and accessible areas, analysis of construction methods, detailed reporting on defects (their cause and significance), and advice on maintenance and repairs. Strongly recommended for: pre-1850 buildings; any property with known or suspected defects; properties that have been significantly altered or extended; converted buildings; listed buildings; or any property where you are uncertain about the extent of any issues.

The Level 3 Building Survey is the survey to commission for the vast majority of London Victorian, Edwardian, and inter-war terrace and semi-detached houses. London's older housing stock almost always has defects that are worth understanding in detail before committing to purchase.

Structural survey / structural engineer's report: a survey focused specifically on the structural condition of the building — the foundations, walls, roof structure, floors, and beams. Carried out by a structural engineer (typically a Chartered Member of the Institution of Structural Engineers, MIStructE). Most useful where there are visible cracks, signs of movement, suspected subsidence, or planned structural alterations. A structural engineer's report is more technical than a RICS survey on structural matters, but does not cover the full building condition.

Damp survey: see the dedicated Damp Survey guide. A specific survey focused on identifying sources of moisture, diagnosing the cause (rising damp, penetrating damp, or condensation), and recommending remedial action. Best commissioned from an independent RICS surveyor rather than a damp-proofing company.

CCTV drainage survey: see the dedicated Drainage Survey guide. Essential pre-purchase for properties where drainage condition may be an issue.

Asbestos survey: required before any demolition or refurbishment work on a property built before 2000. Under the Control of Asbestos Regulations 2012, a management survey should have been carried out on any commercial property, but residential properties are not always surveyed. Pre-demolition surveys are a legal requirement before notifiable refurbishment work.

Japanese knotweed survey: where knotweed is suspected, a specialist survey by a trained surveyor or ecologist confirms presence and extent. Japanese knotweed requires a management plan for mortgage purposes.

RICS accreditation: look for a surveyor who is a Member (MRICS) or Fellow (FRICS) of the RICS, or an AssocRICS (Associate). The RICS Find a Surveyor tool (rics.org) allows you to search for accredited surveyors by location and type of work.

Independence: the surveyor should be independent of the estate agent selling the property, the developer, and (ideally) the lender. Some lenders offer a combined valuation-and-Level-2 survey — while convenient, be aware that the surveyor is primarily appointed by and responsible to the lender.

Local knowledge: a surveyor who works regularly in the specific area of London you are buying in will have better context for local issues — ground conditions, typical construction defects for the area's stock, local drainage infrastructure, conservation area issues.

What to ask: what type of survey are you recommending for this specific property and why? What will you physically access during the inspection? What will not be covered? What specialists would you recommend I engage in addition?

• RICS Level 2 (Homebuyer Survey): £450 to £900 depending on property size and value

• CCTV drainage survey: £150 to £400
• Damp survey (independent surveyor): £250 to £600
