What Does a Level 3 Building Survey Include? A Complete Guide for London Homebuyers
posted 7th October 2025
Buying a property in London is a major investment — and for many buyers, arranging a professional building survey is one of the most important steps in the process. At Tayross Associates, we specialise in Level 3 Building Surveys, also known as full structural surveys, providing detailed insights into a property’s condition before you commit to purchase.
What Is a Level 3 Building Survey?
A Level 3 Building Survey is the most comprehensive type of survey available under RICS guidance. It’s designed for older, larger, or altered properties, as well as those in poor condition or of non-standard construction. Unlike a simple valuation or Level 2 (HomeBuyer) survey, a Level 3 survey offers an in-depth examination of the structure and fabric of the building.
What Does It Include?
At Tayross Associates, our Level 3 Building Surveys cover:
- A thorough inspection of the property, including the roof, walls, floors, windows, doors, chimneys, cellars, and loft spaces.
- Identification of visible defects such as damp, timber decay, structural movement, roof deterioration, or issues with drainage.
- Analysis of potential causes — not just what is wrong, but why the defect has occurred and what the implications are.
- Recommendations for remedial works and advice on priorities, so you can plan repairs effectively.
- Commentary on future maintenance, helping you budget for ongoing upkeep.
- Photographic evidence to support key findings.
Why It Matters for London Properties
Many homes in London, particularly Victorian and Edwardian properties, have been extended or altered over the years. Hidden defects such as outdated wiring, poor insulation, or damp ingress can be costly to address. A Level 3 survey gives you the information you need to make an informed decision — and can also strengthen your position in price negotiations.
