Benefits of LED Lighting Upgrades
Why upgrading to LED is a smart investment
Up to 80% Energy Savings
LED bulbs consume a fraction of the energy used by halogen and incandescent lights, dramatically reducing your electricity bills every month.
Long Lifespan
Quality LED bulbs last 25,000 to 50,000 hours compared to just 2,000 hours for halogen, meaning far fewer replacements over the years.
Superior Light Quality
Modern LEDs offer excellent colour rendering, adjustable colour temperatures, and instant full brightness with no warm-up time needed.
Eco-Friendly Choice
LEDs contain no mercury or harmful chemicals and produce significantly less carbon emissions, making them the environmentally responsible choice.
Reduced Heat Output
LEDs run much cooler than halogen bulbs, reducing fire risk and keeping your rooms more comfortable, especially with recessed downlights.
Increased Property Value
Modern LED lighting upgrades enhance the appeal and value of your property with contemporary, energy-efficient lighting throughout.

Frequently Asked Questions

Yes, this is one of our most popular upgrades. We replace the entire halogen fitting with a modern fire‑rated LED downlight, ensuring compatibility with your existing wiring and any dimmer switches.

A typical home replacing 20 halogen downlights with LED equivalents can save £150–£250 per year on electricity. The upgrade usually pays for itself within 1–2 years through energy savings alone.
