We install outdoor security lighting across St Albans, Harpenden and Hertfordshire, including PIR floodlights, LED security lights and dusk-to-dawn systems. All work is completed by a NICEIC Approved Contractor.
At KG Electrical Contractors, we design and install outdoor security lighting for homeowners across St Albans, Harpenden and Hertfordshire. Whether you want to illuminate a driveway, entrance, side access route, perimeter area or rear garden, we create practical lighting schemes tailored to your property.
From PIR security lights and LED floodlights to security wall lights, motion sensor lighting and dusk-to-dawn lighting, every fitting is carefully selected and positioned to provide effective illumination where it is needed most.
Led by Kyle Gamble, we combine outdoor lighting expertise with qualified electrical knowledge to deliver reliable, energy-efficient security lighting installations completed in accordance with current UK wiring regulations.

















| PIR Setting | What It Controls | Consequence if Incorrectly Set |
|---|---|---|
| Detection Angle | The horizontal area monitored by the sensor (typically 120°–270°). | Too wide: triggers from passing vehicles or neighbouring properties. Too narrow: genuine approaches may not be detected. |
| Sensitivity | The level of heat change required to activate the sensor. | Too high: activates from foxes, cats or moving foliage. Too low: may not detect a slow-moving person in colder conditions. |
| Time-On | How long the light remains illuminated after activation (from seconds to around 15 minutes). | Too short: the light switches off while someone is still present. Too long: unnecessary illumination may disturb occupants during the night. |
We installed discreet lighting and power across three designer gardens at RHS Wisley. Using 32 lights and six power supplies to highlight rare plants and create a calming, immersive evening experience.
During a £14 million spa refurbishment, we worked with leading designers to install lighting for a tranquil courtyard garden — a scheme that brings calm, elegance, and atmosphere as day turns to night.
Working alongside lighting and garden designers, we delivered a bespoke scheme for this six acre estate in Chesham covering ancient trees, meadows, fountains, and formal gardens.
