Professional Lighting That Transforms Your Space
Lighting does more than illuminate a room — it defines the atmosphere, highlights architectural features, and influences how you feel in a space. Poorly planned lighting creates shadows, glare, and uneven coverage. Professionally designed lighting makes every room function better and feel better.
At Cobham Electrical Contractors, we handle every aspect of lighting installation — from selecting the right fittings and planning the layout to running new circuits, fitting dimmer switches, and installing smart lighting controls. Whether you're renovating a kitchen, landscaping a garden, or upgrading an entire property, we deliver results that exceed expectations.
We install all types of domestic and commercial lighting: recessed LED downlights, pendant fixtures, track lighting, under-cabinet lighting, bathroom lighting, outdoor security lighting, garden and pathway lighting, and feature lighting for living spaces, restaurants, and retail environments.
Every installation is designed to complement your property and lifestyle. We advise on colour temperature, beam angles, dimming compatibility, and energy efficiency — ensuring you get the right light in the right place.

Our Lighting Installation Work
The Impact of Poor Lighting
Most properties suffer from inadequate or outdated lighting. A single central pendant in each room was standard decades ago, but it creates harsh shadows, leaves corners dark, and makes tasks like cooking, reading, and working uncomfortable. The consequences go beyond aesthetics:
- Eye strain and headaches from insufficient task lighting in kitchens, home offices, and bathrooms
- Higher energy bills from outdated halogen or incandescent fittings consuming 5–10x more power than LED equivalents
- Reduced property appeal — estate agents consistently identify lighting as one of the top factors affecting buyer perception
- Safety risks from poorly lit stairways, paths, and exterior areas
- Non-compliant bathroom lighting that doesn't meet IP rating requirements for wet zones
- Missed potential — architectural features, artwork, and garden landscaping remain invisible after dark
How We Plan and Install Your Lighting
Consultation & Design
We discuss your requirements, budget, and the effect you want to achieve. We assess the existing electrical supply, ceiling construction, and insulation to plan the installation correctly. For larger projects, we provide a lighting layout drawing.
Product Selection
Based on the design, we recommend specific fittings, lamps, and controls. We source commercial-grade products from trusted suppliers — not the cheapest option, but the best value for longevity, light quality, and energy efficiency.
Installation
We cut apertures, run new cables where needed, fit fire-rated downlight housings, connect fittings, and install switches and dimmer controls. We work cleanly and protect your property throughout.
Testing & Commissioning
Every new circuit is tested to BS 7671 standards. Dimmer compatibility is verified, colour temperatures are confirmed, and beam coverage is checked. We make adjustments until the result is exactly right.
Handover
We walk you through the completed installation, demonstrate controls and dimming, and provide certificates for the electrical work. You receive spare lamp specifications for future reference.
Why Professional Lighting Installation Matters
Energy Savings Up to 90%
LED lighting uses up to 90% less energy than halogen equivalents. A typical kitchen downlight upgrade pays for itself within 12–18 months in reduced bills.
Expert Design Advice
We advise on layout, colour temperature, beam angles, and dimming — not just wiring. The difference between good and great lighting is in the planning.
Fire-Rated Installations
Every recessed downlight is fitted with the correct fire-rated housing to maintain ceiling fire barriers. This is a regulatory requirement that DIY installations frequently miss.
25,000+ Hour Lamp Life
Quality LED fittings last 25,000–50,000 hours. At 4 hours daily use, that's 17–34 years before replacement.
Smart Home Integration
We install Philips Hue, smart dimmers, and voice-controlled systems that let you adjust lighting from your phone or with Alexa/Google Home.
Bathroom & Outdoor Compliance
Bathrooms and outdoor areas have specific IP rating requirements. We ensure every fitting meets the correct ingress protection standard for its location.
Lighting Types, Technologies, and Applications
Recessed LED downlights are the most popular domestic lighting choice in Surrey properties. Available in fixed and adjustable versions, they provide clean, unobtrusive illumination without protruding below the ceiling line. We fit fire-rated downlights as standard — these maintain the ceiling's fire barrier rating (typically 30 or 60 minutes) and prevent hot gases from passing through the aperture in a fire.
Colour temperature is measured in Kelvin (K) and significantly affects the feel of a room. Warm white (2700K–3000K) creates a relaxed, inviting atmosphere ideal for living rooms and bedrooms. Cool white (4000K) provides clearer, more energising light suited to kitchens, bathrooms, and workspaces. We advise on the right temperature for each room based on its function and your preferences.
Dimming is essential for versatile lighting. Not all LED fittings are compatible with all dimmers — using the wrong combination causes flickering, buzzing, and premature failure. We specify compatible trailing-edge dimmers and verify operation during commissioning.
Outdoor lighting serves both security and aesthetic purposes. PIR-activated floodlights deter intruders and illuminate entrances. Pathway bollards and step lights improve safety. Garden uplights and tree lights transform landscaping. All outdoor installations use IP65-rated fittings and UV-stable cabling designed for permanent exterior use.
Under-cabinet lighting in kitchens eliminates shadows on worksurfaces and creates a professional, layered effect when combined with ceiling downlights. We use slim LED strip profiles that are invisible when installed, providing even, shadow-free illumination along the full length of the worktop.
For commercial properties — restaurants, retail, and offices — lighting design follows different principles. Retail lighting emphasises product display with high CRI (Colour Rendering Index) fittings. Restaurant lighting uses warm temperatures and dimming to create ambience. Office lighting must meet minimum lux levels specified in the Chartered Institution of Building Services Engineers (CIBSE) guidelines.
We provide lighting installation services across Cobham, Weybridge, Esher, Oxshott, Walton-on-Thames, Dorking, Godalming, Guildford, and the wider Surrey area. Read our customer reviews or view examples of our work.
