Frequently Asked Questions

1. What is a Level 3 Building Survey?

A Level 3 Building Survey, often called a Full Structural Survey, is the most detailed type of survey offered by a RICS Chartered Surveyor. It offers a detailed assessment of the property’s structure, construction, and condition, highlighting both visible and potential hidden defects. This type of house survey is particularly valuable for buyers investing in older, listed, or non-standard properties. In addition to identifying issues, the survey includes tailored repair advice and estimated costs, giving you a clear picture before committing to purchase.

You should opt for a Level 3 Survey instead of a RICS HomeBuyer Report (Level 2) in situations where the property requires a deeper level of inspection. A Level 3 Survey is ideal if:
• The property is over 50 years old.
• It is a listed or historic building.
• It has unusual or non-standard construction.
• It has been significantly extended or altered.
• The home appears neglected or you suspect structural issues.
• You’re planning major renovation works.

By choosing a Level 3 Homebuyers Survey, you get a more detailed evaluation that can help avoid unexpected repair costs later.

Unlike a Level 2, a Level 3 not only records visible defects but also investigates the likely causes of problems. The report includes detailed repair recommendations, suggested timelines, and cost estimates. This makes it the most reliable type of house survey for buyers wanting a full understanding of the risks and expenses associated with a property.

Yes, and this is one of the main benefits of a Level 3 Survey. The report will provide estimated costs for both urgent repairs and ongoing maintenance. This gives you stronger negotiating power with the seller and allows you to plan your budget more effectively. Many buyers use this information to renegotiate the asking price or to request that repairs be completed before exchange.

All Level 3 Building Surveys are conducted by fully qualified RICS Chartered Surveyors. Our surveyors are accredited, regulated, and experienced in assessing a wide range of properties, from modern builds to complex historic homes. Choosing an RICS-accredited surveyor ensures your house survey is thorough, professional, and backed by industry standards.

Because of the depth involved, a Level 3 Survey usually takes 2- 3 hours to complete, depending on the size and condition of the property. Larger or older homes may take longer, as the surveyor will inspect everything from the roof structure to potential damp issues and structural movement.

Our detailed reports are typically delivered within 3–5 working days. If required, we can provide a faster turnaround.

A Level 3 Homebuyers Survey does not include a property valuation by default. However, if you need a market valuation or a reinstatement cost assessment (for insurance purposes), these can be added as optional extras. Many buyers choose to combine the Level 3 Survey with a valuation to gain both a detailed condition report and an accurate market appraisal.

The report will explain the defect, its likely cause, the risks of leaving it untreated, and the recommended repairs with estimated costs. This information can be used to renegotiate the purchase price or request repairs before exchange.

Absolutely. Once you’ve received your Level 3 Survey report, you can speak directly with your RICS Surveyor. They will clarify any concerns, explain repair priorities, and provide tailored advice on next steps. Having direct access to your surveyor ensures you fully understand the report and can make informed property decisions.

Yes, we handle the entire access process for your house survey. Our team liaises directly with the estate agent or seller to arrange a suitable time for inspection, saving you time and hassle.

Yes. If you’re working to a tight deadline, we can prioritise your booking and provide an expedited service. This is particularly helpful if you are close to exchange or need to make quick, informed decisions during the property-buying process.
