Asbestos was widely used in construction and building materials for many decades because of its strength, durability, heat resistance, and insulating properties. Although its use has been heavily restricted, asbestos-containing materials can still be present in older buildings across London.
For property owners, landlords, employers, facilities managers, and contractors, identifying asbestos before it is disturbed is an important part of managing workplace and building safety. Asbestos surveys in London help identify asbestos-containing materials, assess their condition, and provide information needed to manage potential exposure risks.
The Health and Safety Executive (HSE) explains that buildings constructed or refurbished before 2000 should generally be assumed to contain asbestos unless there is strong evidence that it does not.
What Is an Asbestos Survey?
An asbestos survey is a professional inspection designed to identify asbestos-containing materials (ACMs) within a building or specific area.
The purpose of an asbestos survey is to provide accurate information about the location, amount, type, and condition of asbestos-containing materials. The findings can then be used to create or update an asbestos register and management plan.
Depending on the building and planned activities, different types of asbestos surveys may be required. The two main survey types recognised by HSE are:
- Management Survey
- Refurbishment and Demolition Survey
Choosing the correct survey is important because a management survey is not automatically suitable for planned refurbishment or demolition work.
Why Are Asbestos Surveys Important in London?
London contains a large number of older commercial, residential, industrial, educational, and public buildings. Some properties may have been constructed or refurbished during periods when asbestos was commonly incorporated into building materials.
Asbestos can be found in materials such as:
- Insulation boards
- Cement products
- Roofing materials
- Floor tiles
- Ceiling materials
- Pipe insulation
- Fire doors
- Textured coatings
- Electrical components
- Wall panels
- Gaskets and seals
- Insulation around heating systems
Asbestos is not necessarily dangerous simply because it exists in a building. The risk increases when asbestos-containing materials are damaged or disturbed and fibres become airborne.
A suitable survey helps property owners understand where asbestos may be located so that appropriate management decisions can be made.
Types of Asbestos Surveys
Management Survey
A management survey is designed to help the dutyholder manage asbestos during normal occupation and maintenance of a building.
The survey aims to locate asbestos-containing materials that could be disturbed during normal building use or foreseeable maintenance activities. HSE states that the survey should consider areas such as rooms, corridors, stairs, basements, ceiling voids, lofts, risers, service ducts, lift shafts, roofs, soffits, gutters, and other areas liable to disturbance.
A management survey can form the foundation of an asbestos register and management plan.
Refurbishment Survey
A refurbishment survey is required when planned refurbishment work could disturb the fabric of a building.
This type of survey is more intrusive than a management survey because asbestos can be hidden behind walls, floors, ceilings, partitions, or other building elements.
The purpose is to locate asbestos-containing materials that could be disturbed by planned refurbishment activities so that appropriate action can be taken before work begins.
Demolition Survey
A demolition survey is required before demolition work where asbestos may be present. It is designed to locate and identify asbestos-containing materials throughout the relevant building or structure.
HSE states that asbestos-containing materials should be removed, so far as reasonably practicable, before major refurbishment or demolition. A refurbishment or demolition survey can involve destructive inspection and should be undertaken by a competent surveyor.
What Does an Asbestos Survey Include?
The exact scope depends on the type of survey and the building. A professional survey may involve:
- Reviewing available building information.
- Inspecting accessible areas.
- Identifying suspected asbestos-containing materials.
- Taking representative samples where appropriate.
- Arranging laboratory analysis of samples.
- Assessing the condition of identified materials.
- Recording locations and material information.
- Producing photographs and plans where appropriate.
- Preparing a detailed survey report.
The HSE states that the only way to confirm whether a suspect material contains asbestos fibres is to obtain and analyse an appropriate sample. Sampling should be carried out by a suitably trained person and analysis should use competent accredited laboratories.
What Buildings May Need an Asbestos Survey?
Asbestos surveys can be relevant to many types of properties, including:
- Offices
- Shops
- Warehouses
- Factories
- Schools
- Hospitals
- Restaurants
- Hotels
- Public buildings
- Commercial properties
- Industrial units
- Residential blocks
- HMOs
- Older houses undergoing refurbishment
The legal duty to manage asbestos applies to non-domestic premises and the common parts of multi-occupancy domestic premises, such as purpose-built flats.
The specific requirements depend on the property, its use, construction history, occupancy, and planned work.
Who Is Responsible for Managing Asbestos?
The person responsible for managing asbestos is commonly referred to as the dutyholder.
Depending on the circumstances, this could be:
- A building owner
- A landlord
- An employer
- A property management company
- A facilities manager
- A person responsible for building maintenance
The dutyholder must take reasonable steps to determine whether asbestos is present, assess its condition and risk, maintain an asbestos register, and establish suitable management arrangements.
Where several organisations or individuals share responsibility for a building, they may need to cooperate and communicate information about asbestos.
Asbestos Register and Management Plan
An asbestos survey is only one part of asbestos management.
Information from the survey should be used to create an asbestos register. The register should record known and presumed asbestos-containing materials, including their location, type, quantity, and condition.
HSE describes the asbestos register as a live document that should be kept up to date as circumstances change. It should also contain information about areas that could not be accessed during the survey and where asbestos is presumed to be present.
The asbestos management plan should explain how asbestos risks will be managed. It should identify responsible people, include the asbestos register, and establish arrangements for monitoring the condition of ACMs.
What Happens If Asbestos Is Found?
Finding asbestos does not necessarily mean that it must immediately be removed.
The appropriate management option depends on factors such as:
- Type of asbestos-containing material
- Condition
- Location
- Likelihood of disturbance
- Occupancy
- Planned maintenance
- Future refurbishment
- Potential for fibre release
If an asbestos-containing material is in good condition and unlikely to be disturbed, it may be possible to manage it in place.
Damaged materials may require repair, protection, sealing, or removal depending on the circumstances. HSE recommends that management actions should be clearly defined, time-based, and reviewed as part of the asbestos management plan.
Asbestos Surveys Before Refurbishment
One of the most important reasons to arrange an asbestos survey is planned building work.
Activities such as drilling, cutting, sanding, removing ceilings, replacing flooring, opening walls, installing electrical systems, or altering partitions can disturb hidden asbestos.
HSE states that employers must identify asbestos before building, maintenance, demolition, or other work that could expose workers to asbestos begins. Where existing information is incomplete or unreliable, a suitable assessment or survey may be necessary.
A refurbishment or demolition survey should therefore be completed before relevant structural or refurbishment work starts.
Choosing an Asbestos Surveyor in London
Choosing a competent surveyor is important because asbestos surveying requires appropriate knowledge, training, experience, and risk awareness.
HSE strongly recommends using accredited asbestos surveying organisations. UKAS is the recognised accreditation body in Great Britain for asbestos inspection bodies carrying out surveys.
When choosing an asbestos survey company in London, consider:
- Relevant experience
- Technical competence
- Accreditation
- Professional qualifications
- Insurance
- Survey scope
- Sampling and laboratory arrangements
- Report quality
- Independence and impartiality
- Knowledge of relevant regulations
Do not choose a surveyor based solely on the cheapest quotation. A survey that fails to identify relevant ACMs can create significant problems for future maintenance and refurbishment work.
What Information Should a Survey Report Provide?
A useful asbestos survey report should provide clear and practical information.
Depending on the survey type, it may include:
- Property details
- Survey scope
- Areas inspected
- Areas not accessed
- ACM locations
- Material descriptions
- Sample information
- Laboratory results
- Condition assessments
- Photographs
- Floor plans
- Recommendations
- Risk-related information
The HSE advises dutyholders to check the accuracy of survey reports, including whether diagrams and plans are clear, all relevant areas were accessed, and sufficient samples were taken.
Informing Contractors and Workers
An asbestos register is particularly important when maintenance contractors or other workers are carrying out work on a building.
The dutyholder must provide relevant asbestos information to people who may disturb asbestos, including contractors, maintenance workers, building managers, and employees.
This information should identify the location and condition of known asbestos-containing materials and explain the arrangements for safe working.
Providing this information before work starts can help contractors plan appropriately and prevent accidental disturbance.
How Often Should an Asbestos Survey Be Updated?
There is no single expiry date that automatically applies to every asbestos survey.
The asbestos management arrangements should be reviewed and updated when circumstances change. For example, new building work, changes to the condition of ACMs, accidental disturbance, or alterations to the property may require the asbestos register and management plan to be updated.
HSE states that the asbestos management plan should be reviewed at least every 12 months or sooner when necessary.
A new survey may also be required when planned refurbishment affects areas that were not covered by an existing management survey.
Conclusion
Asbestos Surveys in London are an important part of protecting people from potential asbestos exposure and managing older buildings responsibly. A suitable survey can identify asbestos-containing materials, document their location and condition, and provide information needed for an effective asbestos management plan.
For normal building occupation and maintenance, a management survey may be appropriate. For planned refurbishment or demolition, a more intrusive refurbishment or demolition survey may be required.
Property owners and dutyholders should use competent surveyors, maintain an accurate asbestos register, communicate relevant information to contractors and workers, and review management arrangements regularly. Taking these steps can help reduce the risk of accidental asbestos disturbance and support safer building maintenance and refurbishment.
FAQs About Asbestos Surveys in London
1. What is an asbestos survey?
An asbestos survey is an inspection designed to identify asbestos-containing materials, determine their location and condition, and provide information for managing potential asbestos risks.
2. Do all buildings in London need an asbestos survey?
Not every building automatically requires the same type of survey. However, buildings constructed or refurbished before 2000 should generally be presumed to contain asbestos unless there is strong evidence otherwise.
3. What are the two main types of asbestos survey?
The two main types are management surveys and refurbishment or demolition surveys. A management survey supports normal occupation and maintenance, while refurbishment or demolition surveys are used before relevant building work.
4. Is an asbestos survey required before refurbishment?
Where refurbishment work could disturb asbestos-containing materials, an appropriate refurbishment survey should be carried out before the work begins. HSE states that refurbishment or demolition surveys are used to locate hidden ACMs before relevant work.
5. Does asbestos always need to be removed?
No. If asbestos-containing material is in good condition and unlikely to be disturbed, it may be possible to manage it safely in place. Damaged or high-risk materials may require repair, protection, sealing, or removal depending on the circumstances.
6. Who can carry out an asbestos survey?
Asbestos surveys should be carried out by a competent surveyor with appropriate training, experience, knowledge, and resources. HSE strongly recommends using accredited asbestos surveying organisations.
