LED Lighting Solutions

Cut energy consumption while improving light quality and performance.

Lighting can account for up to 50% of a building’s electricity consumption, making it one of your most significant opportunities for improving efficiency.

Our LED (Light Emitting Diode) lighting service can halve your energy consumption while improving light quality, reliability and operational performance.

Upgrading from traditional fluorescent lighting to modern LED technology can reduce lighting energy use by 40–50%, while delivering brighter, more consistent light and improving the overall working environment.

LED luminaires also last much longer. You’ll gain up to 50,000 hours compared with 10,000–15,000 hours for fluorescent lamps. This means fewer replacements, lower maintenance costs and less disruption to your operations.

We can also optimise your lighting controls. Introducing technologies such as occupancy sensors and daylight detection means lights automatically adjust to how your spaces are used. The result? Lighting that’s only on when it’s needed.

  • Cut lighting energy consumption by up to 50%

  • Improve lighting quality

  • Reduce energy and maintenance costs

  • Lower your carbon footprint

Key features and benefits

Reduced costs

Modern LED luminaires are designed to deliver maximum output with minimal energy use. You can halve your lighting energy consumption with an upgrade, while benefitting from lower ongoing maintenance costs.

Enhanced operational efficiency

LED fittings can last up to 50,000 hours – significantly longer than traditional lighting. You’ll enjoy fewer replacements, lower maintenance costs, and less operational disruption.

Improved light quality

Enjoy brighter buildings and a design tailored to your layout, with room-by-room lux level analysis based on size, usage, and operational needs. You’ll benefit from an improved working environment, with lighting optimised to ensure no over-lit or under-lit spaces and anti-glare solutions for improved visual comfort.

Integrate smart technology

Eliminate wasted energy and ensure lighting is only used when and where it’s needed by integrating smart systems such as occupancy sensors and daylight dimming controls to automatically adjust lighting levels.

Compliance built in

With designs developed to meet relevant industry standards, including emergency lighting requirements, you’ll gain peace of mind that your system is safe, compliant, and future-proof.

Lower your carbon footprint

Inherently low-carbon in design, LED lighting will support your sustainability goals and demonstrate environmental responsibility with lower energy consumption directly correlating to reduced emissions.

 

Complete design and technical support through RIBA Stages 3 – 5

A seamless delivery from start to finish

We ensure quality and compliance throughout design to installation and handover by working closely with contractors and the wider project team.

Tailored lighting design: We turn the lighting concept into a fully developed, coordinated design that works seamlessly with your building’s architecture and services.

Typically, this stage includes:

  • A developed lighting design aligned with the building layout and spatial use
  • Detailed lighting layouts showing luminaire locations and lighting zones
  • Lighting calculations and modelling to confirm illumination levels and consistency
  • Preliminary luminaire schedules outlining fixture types and key technical specifications
  • Development of smart lighting control strategies, including occupancy detection and daylight dimming
  • Integration of artificial lighting with natural daylight to improve comfort and efficiency
  • Energy performance reviews and updated cost estimates to support informed decisions.

Optimal performance built in: Your lighting design is transformed into a fully detailed, technical solution ready for procurement and installation.

Typically, this stage includes:

  • Final lighting design tailored to meet functional and operational requirements
  • Fully coordinated technical lighting layouts including circuiting and control zoning
  • Detailed lighting calculations and compliance checks to meet relevant standards
  • Final luminaire schedules including specifications and mounting details
  • Detailed lighting control design including sensors and control interfaces
  • Emergency lighting design aligned with safety standards
  • Verification of energy performance and sustainability targets
  • Tender procurement and analysis.

From installation to operation: Your lighting system is installed and commissioned exactly as designed.

Typically, this stage includes:

  • Review of contractor submissions – Checking design information, shop drawings and technical submissions
  • Luminaire and equipment approval – Verifying that proposed luminaires and control equipment meet project specifications
  • Design clarifications – Responding to technical queries on layouts, specifications, or controls
  • Technical guidance to contractors right through to commissioning and handover
  • Operation and maintenance documentation (O&M) review – Examining installed systems, manuals, and as built drawings before handover to ensure

Frequently Asked Questions

Most organisations reduce their lighting energy consumption by 40–50% when upgrading to LED lighting. Additional savings can be achieved by integrating smart controls such as occupancy sensors and daylight dimming.

LED luminaires typically last up to 50,000 hours, compared to 10,000–15,000 hours for fluorescent lamps. This significantly reduces the need for replacements and ongoing maintenance.

We work closely with you to plan installation around your operational needs, minimising disruption. Projects can often be delivered in phases or outside of core working hours where required.

 

Yes. LED lighting provides brighter, more consistent, and glare-free light. This creates a more comfortable environment and is proven to improved productivity.

Every solution is tailored to your building, with room-by-room analysis to ensure the right lighting levels for each space, eliminating over-lighting and under-lighting.

Smart controls include technologies like occupancy sensors and daylight detection, which automatically adjust lighting based on how spaces are used. They are highly recommended as they maximise energy savings and improve efficiency.

Yes. All designs are developed to meet relevant industry standards, including emergency lighting and safety requirements, ensuring your system is fully compliant and future-proof.

Payback periods vary depending on your building and usage, but many organisations see a return within 2–5 years through significant energy reduction and maintenance savings.

Yes. We provide end-to-end support across RIBA Stages 3–5, from initial design and technical development through to installation, commissioning, and handover.

Yes. By significantly reducing energy consumption, LED lighting directly lowers your carbon emissions, supporting your organisation’s sustainability goals.

We work across a wide range of sectors, tailoring solutions to suit different building types, operational needs, and user environments.

Not necessarily. We can design a phased upgrade approach, allowing you to spread investment while still achieving energy and performance improvements.
