How much does it cost to run a halogen heater in the UK?
Price updated 9 July 2026 · Q3 2026 (Jul–Sep)
A typical halogen heater (800 W) used 3 hours a day, every day costs about £19.06 a month (£228.72 a year) at 26.11p/kWh.
Halogen heaters warm people rather than air — they emit radiant heat that you feel directly, like sunshine. That makes them cheap for spot heating one person on a sofa, because you can run them at low wattage (many have 400W, 800W and 1,200W bar settings) and still feel warm. They do little to raise the overall room temperature, so they are a targeted, low-cost option rather than a whole-room solution.

- They heat people, not rooms — position matters
- Time spent directly in front of it
- Not suitable for warming a whole room
