Demolition is the process of safely dismantling or destroying a structure to make way for redevelopment, repurposing, or site clearance. At Hughes and Salvidge, demolition is carried out with precision planning, adherence to legislation, and strict health and safety controls to ensure both the site and surrounding environment are protected.

Does demolition require planning permissions?

In most cases, yes. Local authorities often require notification or planning permission before demolition begins, particularly for large-scale or listed structures. A formal notice under the Building Act 1984 (Section 80) is usually required, and additional permissions may apply depending on the site’s location, environmental constraints, and heritage status. Hughes and Salvidge advise clients on these requirements and manage the process to keep projects compliant.

What are the main methods of demolition?

The three main methods of demolition are: Mechanical demolition – using heavy machinery such as excavators, cranes, or high-reach demolition techniques. This method is used for many structures and is tailored to the building’s size, condition and surroundings. Deconstruction (or dismantling) – Taking a building apart piece by piece to recover materials for reuse or recycling. This approach is common for historic buildings and projects involving valuable components. Controlled demolition (including explosive demolition) – Using explosives to bring down structures safely and precisely. This is typically used for tall, complex, or inaccessible buildings where machinery cannot be deployed. Hughes and Salvidge determine the right approach based on the project’s size, structure type, location, and environmental factors.

What is controlled demolition?

Controlled demolition is a highly specialised method where explosives are strategically placed and detonated to collapse a structure in a predetermined direction. This approach is used for tall or complex buildings, industrial plants, and chimneys where mechanical demolition is impractical. Hughes and Salvidge’s in-house expertise ensures this process is carried out with the highest safety standards and minimal disruption to surrounding areas.

When is a Section 80 demolition notice required?

A Section 80 notice is required when you plan to demolish most buildings or substantial parts of them in England and Wales. It must be submitted to the local authority before work begins, giving them the opportunity to set conditions to protect public safety and nearby properties. Hughes and Salvidge assist clients with Section 80 compliance as part of the planning stage.

How is safety managed on a demolition site?

Safety is paramount on every demolition site. It covers everything from securing the perimeter and managing dust, noise, and vibration, to ensuring all operatives follow strict health and safety protocols. Hughes and Salvidge maintain rigorous safety systems, staff training, and environmental controls to safeguard both the workforce and the surrounding community.

How much does a demolition project typically cost?

The cost of demolition varies depending on the size and type of structure, access to the site, environmental considerations, and waste disposal requirements. Additional factors such as asbestos removal or hazardous materials can also affect pricing. Hughes and Salvidge provide transparent costings and tailored solutions, ensuring clients understand the breakdown of their investment.

How does demolition work in an airport environment?

Airport demolition requires unique expertise due to the sensitive nature of the environment, the proximity to live runways, and strict regulatory controls. Hughes and Salvidge have extensive experience in this sector, having delivered major demolition projects within airports safely, efficiently, and without disruption to airport operations.

How to keep your demolition site safe?

Key steps include:Conducting thorough risk assessments and method statements, securing the site with fencing and controlled access, managing hazardous materials such as asbestos before demolition, using dust suppression and vibration monitoring systems and ensuring all workers are trained and competent. At Hughes and Salvidge, these measures are standard practice, reinforced by decades of experience in high-risk, complex environments. For a more detailed breakdown of the safety processes involved, including training requirements, PPE standards, vehicle management and employer responsibilities, you can read our blog on how to keep your demolition site safe.

What does a demolition contractor do?

A demolition contractor manages every aspect of dismantling a structure, from planning and regulatory compliance to the physical demolition and waste recycling. At Hughes and Salvidge, this also includes environmental management, health and safety assurance, asbestos removal through our sister company H&S Asbestos, and the recycling over 97% of site materials to minimise landfill use.

SITE ASSESSMENT

A detailed site assessment forms the foundation of our project planning. We evaluate the condition of the site, identify hazardous materials, and assess structural complexities. This enables us to establish a clear timeline, define safety protocols, and select the most appropriate demolition strategies, ensuring each stage progresses safely and efficiently.

HEALTH AND SAFETY PROTOCOLS

Protecting our staff, the public, and the environment is our top priority. Our health and safety procedures include hazard identification, strict PPE requirements, air quality monitoring, and adherence to regulatory standards. Regular safety briefings, emergency response plans, and controlled site access are also enforced to minimise risk throughout the project.

DECOMTAMINATION AND INDUSTRIAL CLEANING

We specialise in removing hazardous substances such as asbestos, heavy metals, and chemical residues. Our team also performs targeted cleaning of equipment, pipes, and surfaces to reduce contamination risks and prepare the site for demolition. This ensures a safer working environment and protects surrounding ecosystems.

Hazardous Material Removal

If we suspect the presence of hazardous material, such as asbestos or chemicals, we'll factor safe removal and disposal into the demolition plan. Our highly trained operatives will safely handle, package, and dispose of any encountered hazardous materials, following all regulations. Once the work is complete, the site will undergo final testing to ensure that contamination levels have been reduced to acceptable standards for the intended future use of the land.

Environmental Protection and Monitoring

As a responsible demolition company, we will consider the environmental impact of our activities before, during and after the demolition project. From the start, we’ll put measures in place to ensure that we minimise our impact on the environment. We’ll monitor air quality, noise levels and water runoff to prevent the contamination of surrounding areas.

Waste Management and Recycling

We prioritise responsible waste management on all our projects. A comprehensive site waste management plan ensures a streamlined approach, saving time and resources throughout the demolition process. We aim to achieve 97% recycling of demolition waste. For any non-recyclable materials, we guarantee proper disposal and maintain meticulous records of all waste removed from the site.

Structural Demolition Works

We carry out controlled demolition of major structures including cooling towers, boiler houses, and chimneys. Depending on the site requirements, we use methods such as mechanical dismantling, explosive demolition, or high-reach excavators. Every stage is carefully planned to maintain safety and environmental compliance.

Land Remediation and Site Restoration

At the final stage, we restore the land to make it safe for future use. This includes soil testing, contamination removal, and landscape rehabilitation where necessary. Our goal is to eliminate environmental hazards, restore ecological balance, and prepare the site for redevelopment or natural restoration.

Completion and Site Handover

Upon completion, we conduct a final inspection to ensure all demolition, cleaning, and remediation work meets regulatory standards. Documentation is reviewed, and safety certifications are issued. The site is then formally handed over, ready for redevelopment or alternative use, marking the successful completion of the project.

frequently asked questions

What are the timescales for power station demolition projects?

Decommissioning timelines in the UK are highly flexible and tailored to each individual plant. For nuclear power stations, the process can span several decades or even up to a century, depending on the site’s characteristics, technical requirements, and safety considerations.

Typically, nuclear power operators adopt a phased approach to decommissioning, choosing between Early Site Clearance and Deferred Dismantling.

Early Site Clearance
Decommissioning begins soon after the plant ceases operations. All radioactive materials are removed and the site is dismantled promptly, with the aim of returning the area for alternative use within a shorter timeframe.

Deferred Dismantling
The site is placed into a care and maintenance phase, allowing time for radioactive decay. This reduces risk and can lower the cost of dismantling and decontamination in the future. During this period, the site is maintained in a secure and stable condition with ongoing monitoring, with full decommissioning carried out several decades later.

What factors impact the timeline and budget of power station demolition or decommissioning?

Several factors influence the timeline and cost of any power station demolition or decommissioning project, including but not limited to:

Demolition or decommissioning method – such as mechanical dismantling, implosion, high-reach demolition, or deconstruction.
Size and structural complexity of the power station.
Every decommissioning project includes thorough cleaning and decontamination to ensure hazardous materials are safely managed. Contaminated or dangerous substances, such as asbestos, heavy metals, and industrial waste are carefully removed and transported to approved disposal or recycling facilities.
Surrounding land use and development, including the proximity of neighbouring buildings and infrastructure.
Site survey outcomes and regulatory requirements, including risk assessments, planning permissions, and safety measures that must be implemented before work can begin.
