Mechanical Services

Mechanical engineering is central to our business.

We design, install and commission robust, energy efficient systems tailored to each building’s operational demands. Our work ranges from full plant room replacement to specialist services integration within live environments.

Our mechanical capability includes:

  • Heating and low carbon systems
  • Ventilation and air handling
  • Air conditioning and chilled water
  • Domestic water services and plumbing
  • Gas, drainage and specialist pipework systems
  • Steam and compressed air
  • Packaged plant rooms and off site prefabrication

We also deliver sustainable mechanical technologies including air and ground source heat pumps, biomass systems, CHP, grey water recycling and natural ventilation strategies.

Electrical Services

Our electrical engineering services provide compliant, resilient infrastructure for buildings of all scales.

We deliver complete electrical packages from design and specification through to installation, testing and certification.

Our electrical services include:

  • LV distribution and switchgear
  • Lighting and power installations
  • Emergency lighting and standby power
  • Fire detection and alarm systems
  • Access control, CCTV and security systems
  • Data, voice and fibre optic cabling
  • UPS systems and backup power
  • Testing, inspection and maintenance

All installations are delivered in accordance with ECA standards and are independently certified, ensuring compliance and quality assurance.

Renewables and Decarbonisation

We deliver practical Net Zero focused engineering solutions across public and private sector estates.

Our services include:

  • Heat pump integration and system redesign
  • Solar PV and renewable energy systems
  • HVAC modernisation
  • LED upgrades
  • Energy metering and monitoring
  • Carbon reduction aligned infrastructure upgrades

Where Mechanical and Electrical works represent the majority of the scope, we regularly act as Principal Contractor, providing full programme and trade coordination under engineering led control.

Facilities Management

Post project, we provide structured maintenance support to protect system performance and asset longevity.

Our maintenance services include:

  • Planned preventative maintenance
  • Plant replacement
  • Reactive breakdown response
  • Electrical testing and inspection
  • HVAC servicing
  • BMS optimisation and validation

This lifecycle approach ensures buildings remain efficient, compliant and operational long after practical completion.

In House Design

Our in-house design team works seamlessly with our installation and maintenance teams to deliver fully coordinated, intelligent building services solutions from concept to completion.
Using industry-leading platforms including Revit MEP, IES for advanced thermal modelling, AutoCAD and other specialist tools, we provide:
  • Full mechanical and electrical design packages
  • Energy Performance Certificates
  • SBEM, BRUKL and Part L calculations
  • Air conditioning inspections
  • BIM coordination, clash detection and coordination layouts
  • Decarbonisation schemes
We collaborate closely with all members of the wider design team, carry out site visits, and ensure every design is developed in accordance with CIBSE and BESA guidance together with current Building Regulations.
Our team maintains excellence through monthly CPD, structured graduate training programmes, and deep expertise across Revit modelling, thermal modelling, and calculative design. We leverage all available tools in an efficient and prioritised manner to deliver the best possible outcome for our clients.
