Lighting accounts for a meaningful share of the average home's electricity use. Switching to LED lighting is one of the simplest, most cost-effective upgrades you can make — and it pays for itself over time. Here's what you need to know before you make the switch.

Why choose LED?

  • Lower bills: LEDs use up to 80% less energy than traditional incandescent or halogen bulbs. The Energy Saving Trust has more on the potential savings.
  • Longer life: a quality LED can last many years, so you replace bulbs far less often — handy for hard-to-reach fittings.
  • Better light: instant full brightness, dimmable options, and a range of warm-to-cool tones.
  • Lower heat and safer running: LEDs run much cooler than halogen fittings, reducing fire risk.

Where LED upgrades make the biggest difference

Kitchens, living rooms, hallways and stairways — anywhere the lights are on for long periods. Replacing old halogen downlights with modern fire-rated LED fittings is one of the most popular upgrades and instantly modernises a room.

Choosing the right colour temperature

Colour temperature is measured in kelvin (K) and changes the feel of a room:

  • Warm white (2700–3000K): cosy and relaxing — ideal for living rooms and bedrooms.
  • Neutral white (3500–4000K): clean and balanced — great for kitchens and bathrooms.
  • Cool white (5000K+): bright and crisp — useful for garages, offices and task areas.

Dimmers and smart controls

Upgrading is the perfect time to add dimmers or smart lighting. Note that not every LED is dimmable and dimmers must be LED-compatible, so it's worth getting this specified correctly to avoid flicker or buzzing.

Types of LED lighting

  • Downlights: recessed spots for a clean, modern ceiling.
  • Panels and battens: bright, even light for kitchens, garages and utility rooms.
  • Strip lighting: under-cabinet and feature lighting.
  • Outdoor and security lighting: wall lights and PIR-controlled floodlights.

Why use a qualified electrician?

For the best results, have downlights and integrated fittings installed by a qualified electrician. This ensures correct fire-rated fittings, safe wiring, proper insulation clearance and neat placement.
