What Is a Dilapidation Survey?

Before any major construction, renovation, or lease agreement, it’s vital to know the exact condition of a property. That’s where a dilapidation survey comes in. This essential inspection protects both property owners and contractors by documenting the current state of a building before work begins.

At Lab Fit, we often conduct dilapidation surveys alongside our fit-out and refurbishment projects across the UK. Understanding what a dilapidation survey involves — and why it matters — helps prevent disputes, delays, and unexpected costs later on.

Understanding a Dilapidation Survey

A dilapidation survey (sometimes called a condition survey or pre-construction inspection) records the physical state of a property at a specific point in time. It’s usually carried out before construction, demolition, or heavy structural work takes place nearby.

The survey provides a clear benchmark showing cracks, wear, settlement, and other pre-existing issues, so that any new damage caused by construction can be identified and resolved fairly.

Why Dilapidation Surveys Are Important

Whether you’re a landlord, tenant, developer, or contractor, a dilapidation survey is your evidence of truth. It helps to:

  • Protect owners: Document existing defects before work begins.

  • Protect contractors: Avoid false claims of damage caused by nearby work.

  • Support insurance: Provide a professional record in case of disputes.

  • Reduce risk: Prevent costly litigation by having objective documentation.

Without a proper survey, it becomes almost impossible to determine liability for cracks, settlement, or vibrations caused by construction.

When a Dilapidation Survey Is Needed

You should commission a dilapidation survey before:

  • Starting major construction or excavation work near another property

  • Signing or ending a commercial lease agreement

  • Renovating or refurbishing a building with shared boundaries

  • Completing structural alterations to offices, laboratories, or retail spaces

For example, before a lab refurbishment or office fit out project, we often conduct a dilapidation survey to protect both the landlord and tenant.

What a Dilapidation Survey Includes

A professional dilapidation survey is detailed and methodical. It typically covers:

  1. Structural elements – walls, ceilings, floors, and roofs

  2. External features – facades, windows, cladding, and gutters

  3. Surrounding areas – pavements, boundaries, and adjacent buildings

  4. Internal finishes – plaster, paintwork, and flooring

  5. Photographic evidence – high-resolution images with notes

  6. Detailed reporting – written descriptions of visible defects

The resulting report acts as a time-stamped condition record before any project begins.

Who Carries Out a Dilapidation Survey?

Only qualified professionals — usually chartered building surveyors or structural engineers — should perform a dilapidation survey. They have the expertise to spot early signs of movement, cracking, or moisture damage that non-experts might miss.

At Lab Fit, we work closely with experienced surveyors to ensure every project begins with a clear, reliable condition report.

The Process of Conducting a Dilapidation Survey

  1. Site visit and inspection – The surveyor inspects internal and external areas of the property.

  2. Documentation – Notes, sketches, and photographs record existing conditions.

  3. Reporting – A full written report summarises findings, often supported by annotated photos.

  4. Verification – Both parties acknowledge receipt of the report, confirming transparency.

The process is straightforward, yet invaluable for future accountability.

Benefits of a Dilapidation Survey

Commissioning a dilapidation survey offers numerous advantages:

  • Prevents disputes between landlords, tenants, and contractors

  • Provides an independent record for insurance or legal use

  • Protects investments in refurbishment and construction projects

  • Minimises financial risks through early identification of issues

In short, it’s a small upfront cost that can save thousands in potential damage claims.

How a Dilapidation Survey Protects Tenants and Landlords

For tenants, the survey ensures you’re not held responsible for pre-existing damage when your lease ends. For landlords, it provides documentation to support repair claims if deterioration occurs during tenancy.

This makes the dilapidation survey a crucial tool in commercial property management, especially during handover or renovation.

Digital Reporting and Modern Practices

Today, most surveys are fully digital. Reports include high-resolution images, 3D scans, and timestamps. This makes comparisons easier after construction work and provides stronger evidence if a claim arises.

Digital surveys also allow quick sharing with clients, contractors, and insurers — improving transparency across all parties.

Frequently Asked Questions on Dilapidation Surveys

  1. What is the purpose of a dilapidation survey?
    It records the existing condition of a property before nearby construction or lease changes, protecting both owners and contractors from damage disputes.
  2. Who should arrange a dilapidation survey?
    Usually, the developer or tenant commissioning nearby works arranges the survey, but property owners often request one for their own protection.
  3. How long does a dilapidation survey take?
    Most surveys are completed within one to two days, depending on the size and complexity of the property.
  4. Is a dilapidation survey legally required?
    While not mandatory, it is strongly recommended before any construction or major fit-out to avoid future liability issues.
  5. What’s the difference between a condition report and a dilapidation survey?
