LED wattages estimated at 85% less than equivalent halogen/incandescent. Payback assumes ~£3 per LED bulb. Carbon based on UK grid average 0.233 kg CO₂/kWh (2025). This is a quick guide for a ballpark figure, not a quote. Check the working before you rely on it. Thanet Electrical Ltd does not accept liability for loss or cost arising from reliance on these figures, except where the law does not allow that liability to be excluded, including death or personal injury caused by negligence.

Ready to Make the Switch?

We convert halogen downlights to fire-rated LED fittings — neater, safer, and more efficient. Most rooms done in half a day.

Why Switch to LED?

Up to 85% Less Energy

A 6W LED replaces a 40W incandescent or a 50W halogen. The savings add up fast across every bulb in your home.

25,000+ Hour Lifespan

LED bulbs last 15–25 years at normal usage. No more frequent replacements — especially in high ceiling fittings.

Fire-Rated Downlights

We install fire-rated LED downlights that maintain your ceiling’s 30- or 60-minute fire resistance — critical in multi-floor homes.

Save energy, save money, and improve your home’s safety with LED lighting installed by qualified electricians.
