Refurbishment and Demolition Surveys: When You Need One
Legal Requirement
Under the Control of Asbestos Regulations 2012, a Refurbishment and Demolition survey is legally required before any refurbishment or demolition work that may disturb the fabric of a building constructed before 2000. Failure to conduct appropriate surveys can result in significant penalties, project delays, and potential health risks.

What is a Refurbishment and Demolition Survey?
A Refurbishment and Demolition (R&D) Survey is a thorough and intrusive inspection designed to locate and identify all asbestos-containing materials in an area before renovation work or complete demolition. Unlike Management Surveys, which are primarily visual and minimally intrusive, R&D Surveys involve:
- Destructive inspection methods to access hidden areas
- Full access to all voids, ducts, and concealed spaces
- Lifting of floor coverings and inspection beneath
- Opening up of partition walls and ceiling voids
- Extensive material sampling for laboratory analysis
- Detailed documentation of all accessible areas
The fundamental principle behind R&D Surveys is that they must identify all asbestos materials that could be disturbed during the planned work, allowing for their safe removal before construction or demolition begins.
Key Point
R&D Surveys are specifically focused on the areas that will be affected by the planned work. For partial refurbishment (e.g., kitchen renovation), the survey may be limited to just that area. For whole building demolition, the entire structure requires surveying.
When is a Refurbishment and Demolition Survey Required?
R&D Surveys are legally required in specific circumstances:
Refurbishment Scenarios
- Major renovation projects
- Significant structural alterations
- Removing or modifying walls
- Installing new windows or doors
- Extension construction
- Plumbing or electrical rewiring requiring access to voids
- Installing new heating or ventilation systems
- Any work that disturbs the fabric of the building
Demolition Scenarios
- Complete building demolition
- Partial demolition of structures
- Removal of outbuildings
- Soft strip demolition before refurbishment
- Dismantling of plant or equipment
- Removing large sections of a building
- Structural changes affecting load-bearing elements
Age of Building Considerations
R&D Surveys are typically required for buildings constructed before 2000, when asbestos was finally banned in the UK. However, the likelihood of encountering asbestos varies by construction era:
- Pre-1985 buildings: Very high probability of containing multiple asbestos materials
- 1985-1999 buildings: Moderate probability, typically limited to specific materials
- Post-2000 buildings: Very low probability, but imported materials or undocumented renovations could still pose a risk
Even in newer buildings, an R&D Survey may be prudent if there's any uncertainty about materials present or if previous undocumented renovations may have introduced asbestos-containing materials.
R&D Surveys vs. Management Surveys: Critical Differences
Understanding the fundamental differences between these survey types helps clarify why a Management Survey is insufficient for refurbishment or demolition work:
| Aspect | Management Survey | Refurbishment & Demolition Survey |
|---|---|---|
| Purpose | Day-to-day management of asbestos in occupied buildings | Identify all asbestos before construction/demolition work |
| Inspection Method | Primarily visual with minor sampling | Fully intrusive with destructive inspection techniques |
| Coverage | Accessible areas during normal occupancy | All areas affected by planned work, including hidden spaces |
| Sampling Extent | Limited to representative samples | Comprehensive sampling of all suspect materials |
| Building Condition | Conducted in occupied buildings | Usually conducted in vacant areas or outside business hours |
| Report Focus | Risk assessment and management recommendations | Detailed material identification for safe removal |
The critical thing to understand is that a Management Survey cannot be substituted for an R&D Survey when refurbishment or demolition is planned. The Management Survey is simply not designed to identify concealed asbestos materials that could be disturbed during construction work.
The R&D Survey Process
A properly conducted R&D Survey follows a structured process:
Pre-Survey Planning
The surveyor reviews building plans, previous survey data, and construction history. They'll discuss the scope of planned refurbishment or demolition work to ensure the survey covers all relevant areas.
Site Preparation
Areas to be surveyed are typically vacated and secured. This often requires scheduling during evenings, weekends, or planned shutdowns to minimize disruption.
Intrusive Inspection
Surveyors use a range of techniques to access concealed areas: lifting floor coverings, opening up wall panels, accessing ceiling voids, and inspecting behind fixed installations or equipment.
Material Sampling
Samples are taken from all suspect materials following strict protocols to minimize fiber release. Each sample is properly documented and sent to an accredited laboratory for analysis.
Analysis and Reporting
Laboratory tests identify asbestos types present (if any). The surveyor compiles a comprehensive report detailing all findings, including precise locations, material types, and asbestos content.
Removal Recommendations
The report includes guidance on which materials require removal before work can proceed, and whether licensed or non-licensed contractors are needed for different elements.
Understanding R&D Survey Limitations
While R&D Surveys are comprehensive, it's important to understand their limitations:
Potential Limitations
- Structural integrity: Some areas may be inaccessible without compromising structural integrity
- Live services: Areas near live electrical or gas services may have restricted access
- Occupied areas: In partially occupied buildings, certain areas may not be fully accessible
- Historic features: In listed buildings, intrusive techniques may be limited
- Height/access challenges: Some high-level or difficult-to-access areas may require specialist access equipment
These limitations should be clearly documented in the survey report, with recommendations for managing these areas during the refurbishment or demolition project.
Good Practice
Any areas that could not be accessed during the survey should be presumed to contain asbestos until proven otherwise. If such areas will be disturbed during the planned work, additional investigation may be required once they become accessible.
Understanding R&D Survey Costs
R&D Surveys typically cost more than Management Surveys due to their intrusive nature, increased sampling, and the specialist expertise required. However, these costs should be viewed in context:
Typical Cost Factors
- Building size and complexity
- Age and construction type
- Number of samples required
- Accessibility challenges
- Scheduling constraints
- Specific site requirements
- Report detail and urgency
Cost vs. Risk
While R&D Surveys represent an upfront project cost, they should be viewed as essential risk management. The costs of inadequate surveying can include:
- Project delays when asbestos is discovered during work
- Emergency removal costs (typically 3-5x planned removal)
- Potential regulatory fines and enforcement action
- Health risks to workers and occupants
- Potential litigation and liability issues
As a general guideline, R&D Survey costs typically range from £500-£1,500 for residential properties and £1,000-£15,000+ for commercial buildings, depending on size and complexity. These costs are a small fraction of the potential costs associated with discovering asbestos during construction work.
Conclusion: Essential Pre-Construction Safeguard
Refurbishment and Demolition Surveys are not just a regulatory box-ticking exercise—they're a critical safeguard that protects workers, building occupants, and project timelines. By identifying all asbestos-containing materials before work begins, these surveys allow for planned, controlled removal that minimizes health risks and project disruption.
Key takeaways to remember:
- R&D Surveys are legally required before refurbishment or demolition work in pre-2000 buildings
- They are fundamentally different from Management Surveys in scope and methodology
- The intrusive nature of these surveys is necessary to identify hidden asbestos
- Early planning for the survey helps minimize disruption to building use
- The cost of proper surveying is insignificant compared to the potential costs of unplanned asbestos discovery
- Only UKAS-accredited surveyors should be used for R&D Surveys
- Survey findings must be shared with all contractors working on the project
By understanding when an R&D Survey is needed and ensuring it's properly conducted, property owners and project managers can proceed with construction or demolition work with confidence that asbestos risks have been identified and can be safely managed.
