When you buy a property, your mortgage lender arranges a valuation to confirm the property is adequate security for the loan. This is not a survey. It is a brief check that protects the lender, not you. If the property has serious defects, a basic valuation may not identify them, and you have no recourse against the valuer.\n\nLevel 1: RICS Condition Report — The most basic survey option. A visual inspection that reports on the condition of the property using a simple traffic light system (green, amber, red) for each element. It does not include a valuation or detailed advice on repairs. Suitable for new-build properties and modern homes in apparently good condition. Cost: 250 to 400 pounds. Limitation: it will not identify problems hidden behind walls, under floors, or in roof spaces because it is strictly non-invasive.\n\nLevel 2: RICS HomeBuyer Report — The most popular choice for standard residential properties. It includes everything in Level 1 plus a more detailed assessment, a market valuation, an insurance reinstatement figure, and advice on defects that could affect the property's value. The surveyor identifies problems like damp, subsidence, roof issues, and timber defects but does not move furniture or lift carpets. Suitable for conventional properties built after 1900 in reasonable condition. Cost: 400 to 700 pounds depending on property size and location.\n\nLevel 3: RICS Building Survey — The most comprehensive option, previously known as a full structural survey. The surveyor inspects all accessible areas, including roof spaces, cellars, and behind fittings where possible. The report provides detailed analysis of construction, condition, and potential future maintenance issues. It includes advice on necessary repairs with indicative costs. Suitable for older properties (pre-1900), unusual construction, properties that have been significantly extended or altered, listed buildings, and any property where you have concerns about condition. Cost: 600 to 1,500 pounds or more for large or complex properties.\n\nWhich Should You Choose — For new builds: Level 1 is usually sufficient (though a separate snagging survey is also recommended). For standard post-war houses and flats: Level 2 covers most scenarios. For period properties, thatched cottages, unusual construction, basement conversions, or anything that gives you cause for concern: Level 3. When in doubt, choose the higher level — the additional cost is trivial compared to the cost of undiscovered defects.\n\nWhat Surveys Do Not Cover — No standard survey tests the electrical system, gas supply, or drainage. These require separate specialist reports. A survey does not guarantee the absence of problems — it reports on what was visible and accessible on the day of inspection. Japanese knotweed, asbestos, radon, and contaminated land require specific searches or tests.\n\nUsing the Survey to Negotiate — If the survey reveals significant defects, you can renegotiate the purchase price, ask the seller to carry out repairs before completion, request an allowance for the cost of repairs, or withdraw from the purchase entirely. A survey that identifies a 15,000 roof replacement gives you genuine leverage.
