The Challenge

The existing FCDO interiors suffered from outdated lighting systems, inconsistent illumination, and inefficient energy performance. Many fixtures failed to meet current government expectations for energy reduction, and there was limited ability to control lighting dynamically based on occupancy or daylight levels.

This challenge was compounded by the need for full compliance with government and building regulations while maintaining the daily operation of an active institution. The project demanded precision, coordination, and a deep understanding of both energy performance standards and architectural design requirements.

The Solution

Barry Turner & Son implemented a complete lighting and interior transformation plan focused on efficiency, control, and compliance.

The lighting strategy centred on high-efficiency LED systems that deliver excellent colour rendering, low heat output, and long lifespan — aligning with the UK Government’s Lighting Technology Guidance for low-energy performance. Each luminaire was selected to balance illumination quality with sustainability, providing consistent, glare-free light across working areas and corridors.

Smart sensors and IoT-enabled lighting controls were introduced to dynamically adjust brightness based on occupancy and daylight levels. Studies show that such systems can reduce energy consumption by up to 80% when properly implemented (arXiv). These integrations ensured that every lumen of light was used purposefully, supporting the FCDO’s drive toward environmental responsibility.

All fixtures were designed and installed in accordance with UK Building Regulations, which state that at least 75% of fixed lighting in new or refurbished buildings must be low-energy and deliver a minimum efficacy of 45 lumens per watt (Lowe & Oliver).

In addition to lighting, the project encompassed ceiling reconstruction, bespoke wall detailing, and decorative finishes. The architectural design incorporated subtle LED backlighting within arched wall panels, enhancing spatial depth and creating a clean, modern aesthetic that aligned with Lumenloop’s sustainable design guidance for commercial spaces.

Rigorous quality assurance processes were followed throughout, consistent with the FCDO’s Major Project Framework, ensuring all work adhered to strict performance and safety criteria.

The Outcome

The completed refurbishment delivered a seamless balance of form and function — creating a contemporary interior that remains respectful of the building’s history while meeting modern sustainability objectives.

The new lighting system provides enhanced visual comfort, improved energy efficiency, and reduced maintenance requirements. Through a combination of LED technology, intelligent control systems, and thoughtful design, Barry Turner & Son helped the FCDO achieve measurable energy savings and a more comfortable working environment.

This project demonstrates our ability to deliver high-spec institutional refurbishments with precision, compliance, and long-term value. By aligning design excellence with sustainability and efficiency, Barry Turner & Son continues to set the standard for lighting and refurbishment projects across the UK public and commercial sectors.
