Black Friday TV deals for 2021

Black Friday is prime time for TV deals as numerous sets get discounted. Low-end to high-end, small to big, we expect to see TVs from all the leading brands, as well as store brand models, get money off.

It's not the only chance you have to get a good TV, mind you. January to March is a good time to get a bargain as it's the lead up to new ranges of TVs being released.

We're still a bit early for Black Friday deals, but as soon as we get wind of which TVs are going to be on offer, we'll let you know.

Best TV deals for October 2021

Here are the top deals we've found as of 1 October.

2020 models are few and far between at this point, but we're starting to see the prices of 2021 releases start to drop as Black Friday looms ever closer. 

1. LG OLED55CX5LB – £1,049

  • 55-inch 4K TV
  • OLED technology
  • HDR for improved contrast

We like: great remote control, simple to use

We didn’t like: missing some useful apps

This 55-inch 4K model is from LG’s 2020 CX OLED range. OLEDs don’t use backlights; instead, each pixel produces its own light. This gives extra control over which parts of the screen are lit and means OLEDs have better contrast than LCD TVs.

Normally selling for around £1,299, it’s currently discounted to £1,049 at Argos.com.

It's a good price, but is it the right TV for you? Read our full LG OLED55CX5LB review to find out more.

2. LG OLED55G16LA – £1,599

  • 55-inch OLED screen
  • 4K resolution
  • £200 off its usual price

We like: great remote, designed to be wall mounted and comes with its own mount (floor stand costs extra)

We didn’t like: missing some catch-up apps

This high-end 55-inch TV released in 2021 is at the cutting edge of today’s screen technology and has a wealth of gaming features, plus built-in voice control.

Recently this model has recently been selling for around £1799, but a few retailers are currently offering it for £200 less.

You can buy it now for £1599 at AO.com, Boots Kitchen Appliances or Currys/PC World

3. LG 43UP77006LB – £399

  • 43-inch 4K TV
  • LG's smallest 4K TV for 2021 
  • Supports HDR10 and HLG HDR formats

We like: good HD detail

We didn’t like: some confusing menus

This is one of LG's latest 4K TVs for 2021. It's one of the cheaper 43-inch models, but you're still getting HDR, the excellent Magic Remote and voice control.

Retailers don't tend to give significant discounts on new TVs, but John Lewis has knocked a further £30 of the price of this one. You can buy it now for £399 at John Lewis.

Make sure you check it's suitable for your needs: read our full LG 43UP77006LB review before you buy.

4. Samsung UE43TU7020 – £379

  • 43-inch 4K TV
  • Supports HDR10+ advanced HDR format
  • One of the few TVs left on sale from 2020

We like: sharp 4K picture

We didn’t like: doesn't have Samsung's fancy One Remote

Samsung released this cheap range for Black Friday 2020, and this 43-inch model was the smallest. Samsung is one of the only manufacturers to put an advanced HDR format in its basic TVs. This means they're more advanced than their rivals – on paper, at least. You can buy it now for £379 from Argos

Is the TU7020 better than LG's cheap 43-inch option from 2021? Read our Samsung UE43TU7020 review to find out.

5. Sony KD65AG9BU £1,818

  • 65-inch 4K TV
  • OLED technology 
  • Four HDMI inputs and three USB ports

We like: stunning 4K picture

We didn’t like: some issues with the sound

This 65-inch model comes from Sony's top-of-the-range Master Series released in 2019. The OLED technology used by this TV gives must greater control over the screen lighting and improves contrast. 

Usually selling for over £2000, this model can currently be bought for £1818.

But read our full Sony KD65AG9BU review before you commit.

Buy it now for £1818 at Laptops Direct or Appliances Direct 

How to get the best deals on specific TV brands

The big retailers – John Lewis, Currys PC World, Richer Sounds, Argos, AO and Amazon – tend to offer better deals than buying directly from the manufacturer. 

Some retailers have dedicated deals pages where you can find their latest deals on TVs and other electricals. Click on the links below to go straight there:

But a low price on a bad TV isn't really a deal at all. Read our TV reviews before you buy to make sure you don't pick up a 'bargain' that turns out to be anything but.

LG TV deals

Deals on LG TVs are plentiful and it has one of the biggest ranges of any brand. John Lewis and Richer Sounds offer five and six-year warranties on their TVs, so they're good places to start looking. Currys only offers a five-year warranty on some of its TVs. 

Read our LG TV reviews

Panasonic TV deals

Panasonic has one of the smallest ranges, so you won't have as much choice if you're after a Panasonic TV. 

As with LG, you should start your search with the big retailers that offer the longest warranties (Currys, John Lewis and Richer Sounds). If you're looking at Currys, though, be aware that only some TVs have a five-year warranty.

Samsung TV deals

You can buy Samsung TVs directly from its website, but this is often the most expensive approach. You'll find better deals online from the major retailers. 

Read our Samsung TV reviews

Sony TV deals

Sony's TVs are often more expensive than its rivals, although costs have started to come down in recent years. You'll still need to look harder to get a great deal. 

Sony sells TVs through its own Sony Centres online and there are discounts there, as well as a five-year warranty on some models, so it's worth checking.

Head to our guide on the best TVs under £500 and £1,000 to see our favourite budget models.

Which TV features are worth paying for?

4K resolution 

4K TVs cost as little as £350 and even less for store brand models. With four times the number of pixels as Full HD, 4K screens are more detailed, so it's worth spending that little bit extra. Full HD content looks better on a 4K screen, but 4K content makes full use of the technology. More and more of this is arriving through pay TV and streaming services.


Most 4K TVs come with high dynamic range (HDR). This gives brighter whites, darker blacks and a wider gamut of colours. But you need HDR content to see the benefits. 

There are four main formats, two basic and two advanced. HDR10 and HLG come on just about every 4K TV, but Dolby Vision and HDR10+ are usually only on pricier sets. 

These advanced formats aren't essential, though. We've tested TVs that don't use them well at all. In fact, some TVs that use the basic formats have a brilliant HDR picture, so don't feel you must buy a TV with HDR10+ or Dolby Vision.

OLED displays 

Organic LEDs, or OLEDs, are found on some high-end TVs, and they produce dazzling pictures with smooth motion, deep blacks and vibrant colours. 

We’ve been impressed by their picture quality in the lab, but that’s not to say you should discount traditional LED-backlit TVs. Some OLEDs are the best of the best, but you can get an excellent TV that isn't an OLED. Find out more about OLED TVs.

QLED displays 

QLED is the name for Samsung’s OLED-rivalling quantum-dot TVs that we’ve seen in the past few years. Here, light hits a layer of quantum dots that produce bright, vibrant colours. 

More and more of Samsung's range is made up of these TVs. Our tests have discovered there are some excellent QLEDs, but it's not a guarantee of quality.

Which TV brands should you buy?

Four brands dominate the TV market: LG, Samsung, Sony and Panasonic. But some less well-known TVs manufacturers – the likes of Bush, JVC and Celcus – may catch your eye with prices that are difficult to refuse. Is it ever worth punting for one of these smaller brands?

Well, the numbers speak for themselves. Between January 2014 and October 2020, we reviewed close to 900 TVs from Samsung, LG, Sony and Panasonic. More than 200 were Best Buys.

We’ve tested more than 200 TVs from other brands. But these models rarely do well and there's a much higher portion of Don't Buys among them. There is the occasional touch of class from these brands, and we have found a handful of Best Buys, but the bigger brands are where you'll see most of the quality.

Where's the best place to buy a TV?

It's worth shopping around to find the retailer with the best price. Then, once you know the very lowest it's being sold for, you can decide whether it's worth paying a little bit more for the same TV from a tried-and-trusted retailer.

That said, don't be afraid to take the plunge on a retailer you haven't heard of before. Some independent stores can offer great deals both online and on the high street. 

For instance, if you've chosen a slightly older TV, some independent retailers may have an ex-demo model going cheap. But do your research beforehand, especially when buying online. Search for other customers who have bought products from that website and shared their experiences. You'll find reviews of retailer websites on Trustpilot.

Many major retailers also run price-match schemes. 

  • Currys PC World promises to beat the price you'd pay at AO.com, Argos, Asda, John Lewis and Tesco. 
  • John Lewis will match the price of any retailer with a high street shop (so no online-only stores). 
  • Richer Sounds will drop its prices to a fraction below what's offered elsewhere, as long as a product is new and boxed, in stock and offered with a similar guarantee. 
  • AO.com boldly claims to price match every product against any retailer.

Look out for warranties, too. Richer Sounds offers six years on its TVs, John Lewis offers five years, and so does Currys on some TVs.

We also give our own seal of approval to a select number of retailers. Look out for a Which? Recommended Provider logo in store or online. Based on overall satisfaction and how likely people are to recommend it to a friend from our annual survey, only the retailers with the best customer scores earn this coveted accolade.
