How Asbestos Affects Property Transactions and Due Diligence

10 August 2026

During property transactions on buildings constructed before 2000, asbestos is a common consideration. 

While the presence of asbestos may not necessarily prevent a sale from going ahead, understanding whether asbestos-containing materials (ACMs) are present can help buyers, sellers and property professionals make informed decisions.

As part of the due diligence process, asbestos surveys and assessments provide valuable information about the location, condition and management of asbestos-containing materials, helping to identify any potential risks before a transaction is completed.

Why Is Asbestos a Consideration During Property Transactions?

Asbestos was widely used in the construction of domestic, commercial and public buildings for many years due to its insulating and fire-resistant properties. Although its use has been banned in the UK, many older properties still contain asbestos-containing materials.

When buying or selling a property, understanding whether asbestos is present is an important part of assessing the building’s condition. Buyers may want reassurance about any future management requirements, while sellers can benefit from providing clear information about known asbestos-containing materials.

Having an accurate understanding of asbestos within a property also helps reduce uncertainty during the transaction process and ensures any future maintenance, refurbishment or demolition work can be planned appropriately.

What Is Due Diligence in Relation to Asbestos?

Due diligence is the process of gathering and reviewing information about a property before a purchase is completed. In relation to asbestos, this involves understanding whether asbestos-containing materials are present, where they are located and what condition they are in.

This information can help buyers assess any ongoing management responsibilities, identify potential costs associated with future building work and determine whether any additional investigations are required before the transaction progresses.

Rather than assuming asbestos will always need to be removed, due diligence focuses on understanding the level of risk and ensuring appropriate information is available to support informed decision-making.

When Should an Asbestos Survey Be Carried Out?

The need for an asbestos survey will depend on the age of the property, how it will be used and whether any building work is planned. Carrying out a survey at the appropriate stage can help identify asbestos-containing materials before they become an issue later in the transaction.

Before Purchasing a Commercial Property

For commercial properties built before 2000, an asbestos management survey can provide valuable information about the presence and condition of asbestos-containing materials. This helps prospective buyers understand any ongoing management responsibilities and supports compliance where required.

Before Purchasing an Older Home

If you’re buying an older residential property, an asbestos survey can provide reassurance by identifying any asbestos-containing materials that may be present. This can be particularly useful if you intend to carry out maintenance, renovations or alterations after moving in.

Before Refurbishment or Renovation

If refurbishment or structural alterations are planned, an asbestos refurbishment and demolition survey should be completed before work begins. Identifying asbestos-containing materials in advance helps prevent accidental disturbance and allows work to be planned safely.

What Happens If Asbestos Is Found?

Finding asbestos during the due diligence process does not automatically mean a property purchase cannot go ahead. Many buildings constructed before 2000 contain asbestos-containing materials (ACMs), and in many cases these can continue to be managed safely if they remain in good condition and are unlikely to be disturbed.

If asbestos is identified, the survey findings will help determine the most appropriate course of action. This will depend on factors such as the type of material, its condition, where it is located and whether any maintenance or refurbishment work is planned.

Where asbestos-containing materials remain in good condition, they can often be managed in situ through regular monitoring and appropriate management procedures. If materials are damaged or likely to be disturbed, repair, encapsulation or removal may be recommended.

How Can Asbestos Affect Property Transactions?

Asbestos does not necessarily prevent a property transaction from progressing, but it can influence the decisions made by buyers, sellers and their professional advisers.

Understanding whether asbestos-containing materials are present allows buyers to assess any future management responsibilities and factor these into their plans for the property.

If refurbishment or redevelopment is planned, the survey findings can also help identify any additional work that may be required before construction begins.

For sellers, providing accurate asbestos information can help answer questions early in the transaction and reduce uncertainty during the due diligence process.

Having clear survey information available can also help buyers make informed decisions based on the actual condition of the property rather than assumptions about asbestos.

What Information Should Buyers and Sellers Have?

Having access to accurate asbestos information can make the due diligence process more straightforward and help ensure everyone involved has a clear understanding of the property’s condition.

Depending on the building, useful documentation may include:

Reviewing this information before completing a property transaction helps buyers understand how asbestos has been managed and whether any further action may be required following completion.

Asbestos vs Property Transactions FAQs

Can you buy a property that contains asbestos?

Yes. Many properties built before 2000 contain asbestos-containing materials. The presence of asbestos does not automatically prevent a sale, but it’s important to understand where it is located, what condition it is in and how it should be managed.

Does asbestos reduce the value of a property?

Not necessarily. The impact asbestos has on a property’s value will depend on factors such as the type of asbestos-containing material, its condition and whether any remedial work is required. 

A professional asbestos survey can help buyers and sellers make informed decisions based on accurate information.

Do I need an asbestos survey before buying a property?

While an asbestos survey is not always a legal requirement before purchasing a property, it can provide valuable information about the presence and condition of asbestos-containing materials, particularly in buildings constructed before 2000 or where refurbishment work is planned.

What happens if asbestos is found during a survey?

If asbestos-containing materials are identified, the survey will provide details of their location, condition and any recommendations for ongoing management or, where appropriate, repair, encapsulation or removal. In many cases, asbestos can remain safely in place if it is in good condition and unlikely to be disturbed.

Should asbestos be removed before selling a property?

Not necessarily. Asbestos does not always need to be removed before a property is sold. If asbestos-containing materials are in good condition, providing accurate survey information can often give prospective buyers the confidence they need to make an informed decision.

What type of asbestos survey do I need?

The appropriate survey will depend on the property and your plans for it. An asbestos management survey is typically suitable for the ongoing occupation and management of a building, while a refurbishment and demolition survey is required before intrusive building work takes place.
