The Level 3 Building Survey (formerly Full Structural Survey) is the most detailed property inspection available. Essential for older properties, period homes, and any property showing signs of defects.
A Level 3 Building Survey provides the highest level of detail available. The surveyor inspects every accessible part of the property — including roof spaces, basements, sub-floors, chimneys, and service installations — and produces a comprehensive report explaining any defects, their causes, recommended repairs, and estimated remediation costs.
| Property Value | Level 3 Cost |

| Up to £150,000 | £480 – £600 |
| £150,001 – £250,000 | £520 – £680 |
| £250,001 – £400,000 | £600 – £800 |

| £600,001 – £1,000,000 | £950 – £1,400 |
| Over £1,000,000 | £1,400+ |
💡 A Level 3 survey on a Victorian property can easily identify repair issues worth £10,000–£50,000+, making its cost extremely worthwhile. Comparing surveyors typically saves 15–20% on fees.
