Estimated cost to run your TV

£0.10per day used

Uses 0.4 kWh on each day it's used (100 W × 4 h).

Per hour of use£0.030.1 kWh
Per week£0.702.8 kWh
Per month£3.0412.2 kWh
Per year£36.50146 kWh

How it works: cost = power (kW) × hours used × price per kWh. Standing charges aren't included because you pay them whether or not the appliance is on.

Estimates only. Real consumption depends on the model, settings and how the appliance is used.

How TV electricity use is measured

A TV's power use is shown in watts on the label or in the manual. It changes with screen size, display technology, brightness and the content being shown. Standby use is small for most modern TVs but adds up over a year.

How to calculate your TV running cost

Cost = power (kW) × hours used × price per kWh

Example only: at 100 W for 4 hours, a TV would use about 0.4 kWh, costing around £0.10 at 25p per kWh. Used 7 days a week, that's roughly 146 kWh and £36.50 a year. Your own figures may be quite different.

Why actual usage varies

  • Screen size — bigger screens generally draw more power.
  • Brightness and picture mode — vivid or HDR modes usually use more.
  • Display type and age.
  • Hours watched each day, and any connected devices like consoles or soundbars.

Ways to reduce the cost

  • Use an eco or standard picture mode.
  • Lower brightness in a dim room.
  • Switch off at the wall if you don't need standby features.
  • Turn it off when nobody's watching.
