If you’re looking for a high-end OLED at a genuinely tempting price, the LG C5 is the smartest buy around.
It’s a multiple What Hi-Fi? Awards winner, it delivers consistently excellent picture quality across its range of sizes, and – crucially – it’s now available with some seriously attractive discounts.
That last point is especially relevant now that LG has announced the LG C6. While the new model looks undeniably tempting, particularly in its Primary RGB Tandem-boosted largest sizes, it isn’t on sale yet and, when it does arrive, it will launch at full price.
Based on past form, meaningful discounts on the C6 are likely a long way off, which makes the current deals on the C5 particularly compelling.
The C5 offers everything LG’s C-series is known for: a beautifully natural, well-balanced picture, excellent motion handling, and some of the strongest gaming features you’ll find on any TV.
Setup is also refreshingly straightforward, presets are well judged straight out of the box, and performance is consistently impressive whether you’re watching films, streaming TV or gaming.
The C5 is still getting better, too, with a recent update having added support for Dolby Atmos FlexConnect. A great addition if you like the look of LG's new Sound Suite soundbar and speaker system.
The LG C5 range spans six screen sizes, from 42 inches up to 83 inches, and every size we’ve tested has earned a full five-star rating.
Unless you’re specifically chasing the extra brightness of LG’s flagship OLEDs, the C5 hits a near-perfect balance of performance, features and value – particularly at today’s reduced prices.
Below, you’ll find the best current LG C5 deals, updated daily so you can see exactly where the strongest savings are right now.
LG OLED42C5 (42-inch)
Launch price: £1099 / $1399 / AU$1695
Like the other sizes of C5, this isn't a huge step on from its predecessor. But given the quality of the C4, even a modest upgrade still makes for a phenomenal TV – a What Hi-Fi? Award winner, no less.
Instead of the pedestal stand of the other sizes, it has blade-style feet. But it packs all the same gaming smarts (including four HDMI 2.1 ports) of its larger siblings into a package compact enough to serve as a second set, or to suit a smaller lounge.
Of course, it helps that lots of TV makers have shunned the 42-inch size recently, instead opting to go large. But the C5 would stand out even in a crowded market, it's that good.

LG OLED48C5 (48-inch)
Launch price: £1399 / $1599 / AU$2495
The 48-inch model is about as premium as TVs come at this size. Again, you get the same unbeatable gaming spec as the others in the C5 series, including four HDMI 2.1 ports and gaming features like VRR and ALLM.
Competition is much fiercer at this size than at 42 inches, however. So these discounts are very welcome – the price cuts have been more aggressive as the TV gets closer to its one-year anniversary.
The lack of decent audio is more noticeable at this size, so you will want to invest in a decent soundbar. But if you can find a deal, this TV will not disappoint.

LG OLED55C5 (55-inch)
Launch price: £1900 / $1999 / AU$3295
Once you get to 55 inches, manufacturers start equipping their TVs with more sophisticated tech – think more advanced panels capable of delivering brighter pictures. The good stuff, in other words.
That's certainly the case here. Because while the upgrades over the C4 might look a little thin on paper (consisting of just a brighter screen and AI-focussed software), they deliver another stunning TV that's among the best of its size. Hence the 2025 What Hi-Fi? Award.
Yes, the design (unchanged since 2022's C2) is starting to look a bit dated. And yes, the sound is still sub-par, especially given the quality of its visuals. But for a stacked feature set (including unparalleled gaming prowess) and eye-popping picture, the C5 is the best 55-inch TV for most people.

LG OLED65C5 (65-inch)
Launch price: £2700 / $2699 / AU$4295
We haven't tested the 65-inch model, but it should be identical to the Award-winning 55-incher, just slightly bigger.
You can expect the same stellar picture quality, immense gaming specs and webOS operating system, which comes with all the usual streaming apps.
The picture should look all the more engrossing at this size. In our review, we praised the 55-incher's "rich, solid and engaging picture that balances vibrancy and authenticity," along with the "excellent contrast and image solidity."
Throw in comprehensive HDR support and that extensive feature spec, and you've got quite a TV on your hands.
LG OLED77C5 (77-inch)
Launch price: £4499 / $3699 / AU$5995
If you have the space – and budget – for a 77-inch TV, you might feel a little shortchanged by the 40W built-in sound system. But the least you can do is partner it with one of the best soundbars.
Discounts are still likely with this size model, so we certainly wouldn't recommend paying full price. Check out the best deals below.
LG OLED83C5 (83-inch)
Launch price: £5999 / $5399 / AU$7995
With the same 40W sound system as the 55-inch C5, the 83-incher will be woefully underpowered in the audio department. But we'll say it again, you really should buy a separate soundbar.
At this size, something like the KEF XIO, Sonos Arc Ultra or Sennheiser Ambeo Soundbar Max should suffice. Anything less, and you really aren't doing it justice.
The 83-inch C5's stand is a little wider to accommodate its massive size. But otherwise, this TV has an identical spec to the 55-inch size and above.
Is the LG C5 worth it?
It is. It earned five stars in all three sizes we've reviewed, with the 42- and 55-inch sizes winning What Hi-Fi? Awards. Now that the prices are dropping, it's better value than ever.
Is the LG C5 good for gaming?
It's incredible how many TVs still only offer two HDMI 2.1 ports. But you'll be glad to hear that the LG C5 isn't among them.
Four HDMI 2.1 ports mean you can stay connected to three next-gen gaming consoles / gaming PCs and a soundbar at the same time, with no port switching required.
HDMI 2.1 gives you support for various gaming features like VRR, ALLM and 4K/120Hz, meaning less lag and clearer picture quality while you play.
Does the LG C5 have a heatsink?
No, it does not. Nor does it have the pricier G5's Primary RGB Tandem OLED panel, nor the now-retired MLA OLED technology of 2024's G4. But it still manages to be brighter than the C4 – LG hasn't said by how much, but it is noticeable, as we commented in our reviews.
