OLED TV Running Costs UK — Will It Wreck Your Electricity Bill?

You've found the TV. It's a big spend, and with energy bills still high, the question naturally follows: is this thing going to quietly add £20 a month to your electricity bill? Here's the honest answer, with real numbers.

How Much Power Does an OLED TV Actually Use?

A 65-inch OLED TV typically draws around 100–150 watts during normal viewing — noticeably less than older plasma or large LED-backlit TVs of the same size, because OLED pixels only light up where needed rather than running a constant backlight.

At current UK electricity prices (roughly 27–30p per kWh), watching for 4 hours a day works out to approximately 11–16p per day, or around £3–£5 a month for typical evening viewing. Over a full year of regular use, that's roughly £35–£60 — genuinely modest against the upfront cost of the TV itself.

Does Screen Size Make a Big Difference?

Yes, but less than you'd expect. Going from 55-inch to 65-inch typically increases power draw by around 20–30%, not double. The jump in picture impact for a World Cup match is far more significant than the jump in running cost.

Brightness Settings Matter More Than Screen Size

The single biggest factor in real-world running cost isn't the TV's size — it's the brightness setting. Most TVs ship in a "Vivid" or "Standard" picture mode that's significantly brighter (and more power-hungry) than necessary for a normally-lit living room. Switching to "Filmmaker Mode" or a calibrated cinema setting both looks more accurate and can meaningfully cut power draw, sometimes by 20% or more.

The Honest Comparison

For context: a typical electric oven uses 2,000–3,000 watts — 10–20 times what an OLED TV draws. A kettle briefly pulls even more. An evening of TV watching costs less than running a single load of washing on a hot cycle.

The Verdict

An OLED TV will not meaningfully impact your electricity bill. A few pounds a month for genuinely excellent picture quality is a reasonable trade-off, and OLED is actually more efficient than older large-screen LED technology was, not less.
