Do I Need an Asbestos Survey Before Renovating a House?
Planning a renovation? Whether you're knocking through a wall, replacing a kitchen, rewiring a property or carrying out a full refurbishment, asbestos is something that should be considered before work begins - particularly in homes built or refurbished before 2000.
Asbestos-containing materials can be hidden behind walls, above ceilings, beneath flooring and within other parts of a building that may only be exposed once work starts.
Finding them after a project has begun can mean stopping work unexpectedly. More importantly, disturbing asbestos without the correct precautions can put homeowners, tradespeople and other occupants at risk.
So, do you need an asbestos survey before renovating your home? Here's what you need to know.
When Is an Asbestos Survey Needed Before Renovation?
If your planned work is likely to disturb parts of a building where asbestos-containing materials (ACMs) could be present, the area should be properly assessed before work starts.
This can apply to projects such as:
Removing or altering walls and partitions
Kitchen and bathroom refurbishments
Rewiring and electrical upgrades
Plumbing and heating alterations
Removing ceilings or textured coatings
Lifting or replacing old flooring
Roof alterations
Loft conversions
Extensions involving the existing building
Structural alterations
Partial or complete demolition
Even a relatively small project can expose previously hidden materials.
For example, chasing a wall for new electrical cables, lifting old floor coverings or removing boxing around pipework may disturb materials that haven't been visible during normal occupation.
Why Are Properties Built Before 2000 Important?
Asbestos was used extensively in UK construction before its use was prohibited.
This means many older properties can still contain asbestos-containing materials. Their presence doesn't automatically make a property dangerous; the risk increases when materials containing asbestos are disturbed or damaged and fibres are released.
Renovation work is therefore particularly important because drilling, cutting, sanding, breaking and removing building materials can disturb previously concealed ACMs.
If you're unsure whether asbestos could be present, it's better to establish what you're dealing with before the builders start opening up the property.
What Type of Asbestos Survey Do I Need for Renovation Work?
For work that will disturb the fabric of a building, you may require an Asbestos Refurbishment Survey.
Unlike a standard Management Survey, which is primarily intended to help manage asbestos during normal occupation and routine maintenance, a Refurbishment Survey is designed around the work you are actually planning.
The surveyor investigates the areas that will be affected by the refurbishment and looks for asbestos-containing materials that could otherwise remain hidden.
Because of this, the inspection can be intrusive.
Depending on the proposed work, this may involve investigating behind wall coverings, within voids, beneath flooring, above ceilings or in other concealed areas.
At Breathe Environmental Services, we tailor the survey scope to the proposed works so the relevant areas can be properly investigated before refurbishment begins.
Do I Need the Whole House Surveyed?
Not necessarily.
A Refurbishment Survey can often be targeted specifically at the areas affected by your planned work.
For example, if you're completely refurbishing one bathroom but aren't touching the remainder of the property, the intrusive survey may only need to cover the bathroom and the building elements affected by that project.
For a much larger renovation involving walls, ceilings, floors, services and several rooms, the survey scope would naturally be wider.
This is one reason it's useful to provide your asbestos surveyor with as much information as possible about the proposed work.
Plans, drawings, photographs or simply a clear description of what your builder intends to remove or alter can help establish the correct survey scope.
What Materials Might Be Checked?
Asbestos was incorporated into many different building products.
Depending on the age and construction of the property, a survey may need to consider materials such as:
Textured coatings
Asbestos insulating board (AIB)
Ceiling panels
Pipe insulation and lagging
Cement sheets and panels
Soffits and undercloaking
Old floor tiles and associated products
Roofing materials
Panels around boilers, heaters or electrical equipment
Boxing and service ducts
Other concealed building materials
You cannot reliably confirm whether a material contains asbestos simply by looking at it.
Where appropriate, representative samples can be taken and sent for laboratory analysis to establish whether asbestos is present.
Can My Builder Just Check for Asbestos?
Builders and other tradespeople should be asbestos-aware, but visual inspection by a builder isn't a substitute for an appropriate asbestos survey.
Many asbestos-containing materials resemble ordinary building products, while others may be completely concealed until the structure is opened.
If suspicious material is discovered once work has started, work in that area should stop until the material has been properly assessed.
Getting the correct survey carried out beforehand can therefore help avoid unnecessary uncertainty and disruption once your project is underway.
What If I Already Have an Asbestos Management Survey?
This is an important distinction.
An existing Asbestos Management Survey doesn't necessarily provide enough information for intrusive refurbishment work.
Management Surveys are intended primarily to identify and manage asbestos that could be disturbed during normal occupation and foreseeable maintenance.
Refurbishment Surveys have a different purpose: investigating the parts of the building that will be disturbed by the proposed project, including concealed areas where necessary.
So if you're about to knock through walls, remove ceilings, replace floors or significantly alter part of the building, don't assume an older Management Survey automatically covers the work.
The survey information needs to be suitable for the actual project being undertaken.
What Happens If Asbestos Is Found?
Finding asbestos doesn't necessarily mean your entire renovation has to stop or that every asbestos-containing material in the property must be removed.
What happens next depends on factors including the type and condition of the material, its location and whether your planned work will disturb it.
The survey results allow the next steps to be properly planned before refurbishment begins.
Where removal or other asbestos work is required, the appropriate procedures and suitably competent contractors can then be arranged before the affected building work proceeds.
Is Asbestos Testing the Same as an Asbestos Survey?
No.
Asbestos sampling and testing can be appropriate when you have a particular material that needs to be identified — for example, a textured coating, floor tile or cement panel.
A Refurbishment Survey has a broader purpose. It assesses the relevant area of the property in relation to the work you're planning and investigates where asbestos-containing materials could be disturbed.
If you're unsure whether you need individual asbestos testing or a Refurbishment Survey, tell us what work you're planning and we can advise on the appropriate approach.

Frequently Asked Questions
Do I need an asbestos survey before replacing a kitchen?
It depends on the age of the property and the work involved. If the refurbishment will disturb walls, ceilings, flooring, boxing, service areas or other building fabric where asbestos could be hidden, an appropriate refurbishment survey may be required before work starts.
Do I need an asbestos survey before knocking down a wall?
Where a wall or surrounding building fabric could contain concealed asbestos-containing materials, this should be established before intrusive work begins. A Refurbishment Survey can investigate the area affected by the proposed alteration.
Does a house built before 2000 definitely contain asbestos?
No. The age of a property indicates the possibility of asbestos use; it doesn't prove asbestos is present. Appropriate inspection and, where required, laboratory analysis are used to identify suspected asbestos-containing materials.
Can asbestos be left in place?
In some circumstances asbestos-containing materials can remain in place if they are in suitable condition, aren't likely to be disturbed and can be appropriately managed. However, refurbishment work changes the situation if the proposed work will disturb those materials.
How long does an asbestos survey take?
This depends on the property, the size of the area being surveyed and the scope of the proposed work. Breathe Environmental will establish the required survey scope before attendance and explain the expected reporting timescale when arranging your survey.
