Detailed Example Survey Document
Below is a breakdown of what you can expect to find in a professional Level 3 Building Survey report. This example highlights the level of detail and structure that characterizes a comprehensive building assessment.
| Report Section | Contents | Purpose |
| Introduction | Property details, client information, survey date, weather conditions, limitations | Establishes scope and context of the survey |
| Property Description | Construction type, approximate age, size, layout, orientation, modifications | Provides baseline understanding of the property |
| External Condition | Roof, chimneys, gutters, walls, windows, doors, drainage | Assesses external envelope integrity |
| Internal Condition | Ceilings, walls, floors, staircases, fireplaces, kitchen, bathrooms | Evaluates internal elements and finishes |
| Services | Electrical, plumbing, heating, ventilation, drainage | Reviews essential building services |

Structural Assessment Example
The structural assessment section of a Level 3 Building Survey provides detailed analysis of the property’s structural elements. Here’s an example of what this might include:
“The property’s load-bearing walls show signs of historical movement, evidenced by stepped cracking to the southeast corner. Monitoring pins installed in 2018 indicate this movement has stabilized. The roof structure exhibits some deflection but remains structurally sound with no evidence of excessive loading. Floor joists in the kitchen extension require reinforcement where notched for service penetrations.”

Material Analysis
A thorough Level 3 Building Survey includes detailed analysis of construction materials and their condition. This helps identify potential issues related to specific materials and construction methods.
| Building Element | Material | Condition Assessment | Recommendations |
| External Walls | Solid brick (215mm) | Generally sound with localized areas of spalling brickwork and deteriorated pointing | Repoint using lime mortar to affected areas; replace spalled bricks |
| Roof Structure | Traditional cut timber | Evidence of past woodworm activity; 2 rafters showing signs of water damage | Treat for woodworm; reinforce or replace damaged rafters |
| Roof Covering | Natural slate | Multiple slipped and cracked slates; nail fatigue evident | Comprehensive roof overhaul required within 2 years |
| Ground Floor | Suspended timber | Localized softening near bathroom; inadequate ventilation to subfloor | Improve subfloor ventilation; replace affected floorboards |
| Windows | Timber sash | Decayed sills and lower rails; several sashes painted shut | Overhaul windows; replace decayed timber elements |
Defect Classification System
Level 3 Building Surveys use a standardized condition rating system to classify defects according to their severity and urgency. This helps prioritize repairs and maintenance actions.
| Condition Rating | Description | Action Required |
| 3 | Defects that are serious and/or need urgent repair, replacement or investigation | Immediate action required; may affect purchase decision |
| 2 | Defects that need repairing or replacing but are not considered serious or urgent | Repairs needed but not immediately; budget for future work |
| 1 | No repair is currently needed; normal maintenance required | Monitor as part of regular maintenance |
| NI | Elements not inspected | Further investigation may be required |
Important: The condition rating system provides a standardized way to communicate the severity of defects. A single Condition Rating 3 defect could significantly impact your purchase decision or require substantial budget allocation for repairs.
Cost Estimation Tables
A comprehensive Level 3 Building Survey includes estimated costs for necessary repairs and maintenance. These estimates help buyers understand the financial implications of the survey findings.
| Defect | Condition Rating | Estimated Cost Range | Timeframe |
| Roof replacement (natural slate) | 3 | £8,000 – £12,000 | Within 12 months |
| Damp treatment to basement | 3 | £3,500 – £5,000 | Immediate |
| Timber window overhaul | 2 | £2,500 – £4,000 | Within 2 years |
| Repointing brickwork | 2 | £1,800 – £2,500 | Within 2 years |
| Electrical system upgrade | 2 | £2,000 – £3,500 | Within 12 months |
Note: Cost estimates are indicative only and based on average prices at the time of the survey. Actual costs may vary depending on the contractor, materials used, and the full extent of work required once repairs begin.

Frequently Asked Questions
How much does a Level 3 Building Survey cost?
Level 3 Building Survey costs typically range from £700 to £2,500+ depending on the property’s size, value, age, and complexity. Listed buildings, larger properties, and those with unusual features generally cost more to survey due to the additional time and expertise required.
How long does a Level 3 Building Survey take to complete?
The on-site inspection typically takes 4-8 hours depending on the property size and complexity. The surveyor will then need 3-5 working days to prepare the comprehensive report. In total, you should allow 1-2 weeks from commissioning the survey to receiving the final report.
What’s the difference between a Level 3 Building Survey and a Level 2 Homebuyer Survey?
A Level 3 Building Survey is more comprehensive than a Level 2 Homebuyer Survey. Level 3 surveys provide detailed analysis of the property’s construction, condition, and defects, including advice on repairs and maintenance. Level 2 surveys are less detailed, using a standardized format and condition rating system without the in-depth analysis and recommendations found in a Level 3 report.
Can I use a Level 3 Building Survey to negotiate the property price?
Yes, a Level 3 Building Survey is an excellent negotiation tool. If the survey identifies significant defects or necessary repairs, you can use this information to negotiate a price reduction or ask the seller to fix the issues before completion. The detailed cost estimates provided in the report give you concrete figures to support your negotiation.
Conclusion
A Level 3 Building Survey represents the gold standard in property assessment, providing comprehensive analysis of a building’s condition, construction, and defects. For older properties, listed buildings, unusual constructions, or properties requiring renovation, this detailed survey offers invaluable insights that can inform purchase decisions, renovation plans, and maintenance strategies.
By understanding the components of a professional Level 3 survey and following best practices for commissioning and using the report, you can maximize the value of this investment and protect yourself from unexpected property issues. Remember that while the cost of a Level 3 survey may seem significant, it represents a small fraction of the property’s value and can potentially save you thousands in unforeseen repair costs.
