Smoke Control & Smoke Ventilation Services

We provide specialist support across the full lifecycle of smoke control and smoke ventilation systems, from installation and commissioning support through to planned maintenance, fault finding and remedial works. We understand the importance of smoke control systems as life safety systems, and we approach every project with a focus on quality, reliability and practical delivery on site.

Complete Smoke Control Installation Packages

Nexus delivers complete smoke control installation packages for residential, commercial and mixed-use developments. We work across high-rise apartment schemes, communal smoke ventilation systems, stair cores, smoke shafts, basements, plant areas, car parks and commercial buildings, supporting clients with both new-build and refurbishment works.

Our smoke control installation works include:

First fix and second fix installation works

Containment and cable installation

Smoke control panels and associated control equipment

AOV controls and field devices

Smoke control dampers and damper wiring

Actuator and vent wiring

Smoke extract and ventilation controls

Power and control cabling

Local isolators, interfaces and associated accessories

Final terminations, labelling and installation completion works

We work closely with clients, project teams and system providers to ensure installations are completed in a practical, organised and coordinated manner, with a strong focus on quality and programme.

Commissioning Support

Bringing a smoke control system to completion often depends on the quality of the pre-commissioning stage. Nexus provides commissioning support to help ensure systems are properly prepared, faults are identified early, and commissioning engineers can work through a clean and organised handover stage.

Our commissioning support can include:

Pre-commissioning checks

Dead testing and circuit verification

Point-to-point testing

Fault identification and rectification

Final snagging and completion works

Assistance during commissioning visits

Support through ATP / witness testing stages where required

This service is particularly valuable on projects where systems have multiple interfaces, phased handovers or where there is a need to work through outstanding defects ahead of final completion.

Servicing & Planned Maintenance

We provide servicing and planned maintenance support for smoke control systems in occupied buildings and existing developments. Routine maintenance is essential to keeping smoke control systems in good working order and identifying faults, wear or damage before they lead to failure or non-compliance.

Our smoke control servicing and maintenance support can include:

Planned maintenance visits

Routine system inspections

Testing of smoke control equipment and associated devices

Inspection of panels, controls, dampers, vents and actuators

Identification of faults, wear or incomplete works

Recommendations for repairs, upgrades or remedial works

We can support managing agents, landlords, building owners, FM providers and commercial clients looking for a practical contractor to help maintain existing smoke ventilation systems.

Reactive Repairs & Fault Finding

When a smoke control system develops a fault, has incomplete works, or simply is not operating as expected, Nexus can assist with fault finding and repair works. We take a practical, methodical approach to diagnosing issues and carrying out the necessary rectification works to restore the system to proper working order wherever possible.

This can include:

Fault finding on smoke control systems

Investigation of non-operational vents, dampers or controls

Diagnosis of wiring, control or panel faults

Repairs to damaged components or associated equipment

Return visits to rectify legacy issues, incomplete works or defects

Remedial Works & System Upgrades

We also undertake remedial works to existing smoke control systems, whether arising from inspection findings, commissioning issues, incomplete installations or poor-quality legacy works. In many cases, clients need a contractor who can step in, understand what has been installed, and carry out practical improvements to bring the system to a more reliable and serviceable standard.

Typical remedial works may include:

Replacement of damaged or defective components

Rewiring or re-termination of circuits

Installation corrections and quality improvements

Additional containment and cable management works

Upgrades to existing smoke control installations

Modifications to suit refurbishment or system changes

Domestic & Commercial Electrical Services

Alongside our smoke control work, Nexus also provides a broad range of domestic and commercial electrical services. We support private clients, landlords, managing agents, contractors and commercial customers with electrical installation, inspection, testing, remedial works and fault finding.

Electrical Installations

We undertake a range of electrical installation works, from smaller additions and alterations through to larger installation packages linked to construction, refurbishment or upgrade projects.

This can include:

First fix and second fix electrical works

Power and lighting installations

Small power and general electrical installation works

Containment and cable installation

Circuit additions and alterations

Electrical works linked to smoke control and ventilation systems where required

Inspection, Testing & EICRs

We carry out inspection and testing works including Electrical Installation Condition Reports (EICRs) for domestic and commercial properties. Whether for ongoing maintenance, property sale / purchase, landlord requirements or general condition assessment, we provide clear reporting and practical feedback on the condition of the installation.

Electrical Remedial Works

Where defects or non-compliances are identified during inspection or testing, we can carry out the necessary remedial works to rectify issues and improve the safety and condition of the installation.

This can include:

Rectification of defects identified during EICRs

Replacement of faulty accessories or damaged components

Earthing and bonding improvements where required

Circuit-related remedial works

General electrical repairs and corrective works

Fault Finding & Repairs

We also provide electrical fault finding and repair services for domestic and commercial systems. Whether it is a persistent fault, damaged accessory, issue with a circuit, or a need to investigate an existing installation, we aim to provide a practical and straightforward service.

Upgrades, Alterations & Small Works

From minor additions and modifications through to wider upgrade works, Nexus can support clients with electrical alterations and small works as part of ongoing maintenance, refurbishment or property improvement projects.

Specialist Smoke Control Experience

Smoke control systems are a core part of what we do. We understand the practical challenges of delivering these systems on site, as well as the importance of getting life safety installations completed, tested and maintained properly.
