LED lighting upgrade for NHS Low Secure Unit

Experts in Renewable Energy

Overview

Our experienced electricians replaced six floors of lighting with energy-efficient LEDs and controls in a Low Secure Unit (LSU) for East London NHS Foundation Trust at Wolfson House in late 2025.

Barton Knight worked with principal contractor Quinn London Ltd on this £400,000, 14-week project. 

Energy efficiency/saving was a key consideration. The lighting on all six floors of the property was replaced with modern LED fittings.

Good housekeeping and close communication with the Project Manager, clinical and estates staff were essential on this project.

Key Works

  • Most of the fittings were from lighting manufacturer Dextra, with others from Designplan and Light Years Ahead, all supplied by Edmundson Electrical. Many included 0-10v dimming controls to adjust the lux levels.
  • All lighting was 4,000 Kelvin, a neutral light temperature mimicking natural daylight.
  • 600×600 square ceiling panels and strip/linear lights were specified for offices and communal areas, with round bulkhead fittings in bedrooms.
  • All fittings were anti-ligature and tamper-proof, and securely mounted.

Wolfson House is a low secure mental health facility in North-East London. One of the particular challenges of completing a lighting upgrade for a Low Secure Unit (LSU) was planning and coordinating with staff. Barton Knight’s engineers worked in a live environment, including upgrading the lighting in patients’ rooms. Two trained escorts per team of 2-3 engineers were always required. Barton Knight coordinated with Quinn London who worked with the Trust’s Project Manager.

Good housekeeping was essential. For the safety of patients, staff and engineers, no equipment (tools, steps, light fittings and more) were left unattended. Tools were always in sight and workspaces are kept as tidy as possible.

On-site storage was limited with only one small, secure shipping container allowed on site.Barton Knight’s off-site team coordinated closely with the Project Manager and site team to ensure equipment and new fittings were delivered at the right time to avoid schedule delays. Old fittings were removed by ‘wait and load’ vans (no skip allowed on site) for safe and WEEE-compliant disposal/recycling each evening.

Barton Knight’s engineers established an excellent relationship with staff and floor managers on site – liaising directly with them on the Programme of Works.
