For Complete Peace of Mind onComplex or Older Properties
When you need a deep dive into a property’s condition—especially one that’s older, larger, or extensively altered—our Level 3 (Building Survey) delivers the full picture. Designed for buyers who need more detail, it covers everything from structure to services, with tailored insights and professional advice.

What Is a Level 3 (Building Survey)?
A Level 3 survey is the most detailed inspection we offer. It includes a full internal and external assessment of the property, along with outbuildings, driveways, and gardens. Not only does it identify defects, but it also provides a diagnosis and recommends any necessary remedial work. Like our Level 2 survey, it uses a clear traffic light system:
Red

Condition Rating 3

Urgent or serious issues

Amber

Condition Rating 2

Minor defects

Green

Condition Rating 1

No repairs needed

The report can also include a professional valuation, giving you added confidence during the buying process.

What's Included?

Full internal and external inspection

Diagnosis of any defects and suggested remedial action

Traffic light condition ratings

Assessment of structural movement, damp, dated services, and more

Optional valuation (unlike most Level 3 surveys)

Post-survey call to discuss findings with your surveyor

Supporting images and clear, jargon-free language

Survey inspection details

This survey is ideal for properties that are:

  • Pre-1900 or listed
  • Heavily extended or structurally complex
  • In poor condition or in need of refurbishment
  • Large in size with multiple levels or unusual layouts
You'll receive a comprehensive, detailed report with extensive supporting images and clear, jargon-free language. The report not only identifies defects but also provides a diagnosis and suggests necessary remedial actions to help you understand exactly what you are buying.
