Best Powerline Adapters For UK Home Broadband In 2019

As a cord cutter, why would you need the best powerline adapter? It’s simple: for cable TV cord cutters, it’s all about broadband and speed. And for video and streaming TV, WiFi is often not enough. So whether you need to connect a TV or a computer to a fast broadband connection – you might need a better solution.

For you to be able to watch streaming TV like Netflix (instead of cable or satellite-based TV, such as from Sky or Virgin), your TV has to be connected to the internet. The connection might be direct to the TV, if you have a “Smart TV”, or through your streaming device (such as the Amazon Fire TV) – but one of these two has to be connected to the internet for the programmes to stream into your living room.

In this article, I review the best Powerline Adapters you can buy in the UK in 2019 – for cord cutters, and general internet home use.

Are Powerline Adapters Better Than Wifi?

Since you’re most likely already connected to the internet with a router in your house, you probably already have a WiFi connection spread around the house. So, you might ask, if WiFi is good enough for using my smartphone or laptop around the house, why not use it for the telly?

The answer really depends on your situation. Generally speaking, HD streaming video needs a lot of bandwidth. According to Netflix, an HD stream uses up to 3GB per hour, and their 4K streams use up to 7GB per hour.

This means that if you’re watching one episode of Stranger Things in 4K, your TV would have to download almost 7GB of data. And since no one likes buffering, your internet connection – particularly the part connected to your TV – needs to be fast enough so it can catch up.


What Is Buffering?

Streaming TV is being downloaded to your device in real-time. In order to prevent disruption in the middle of the programme/movie you’re watching, a small portion of it will be preloaded into your device.

Then, while you’re already watching, the device will keep downloading the next chunk and the one after that, with you still watching the previous chunk that was already downloaded.

If your WiFi connection (or broadband in general) is too slow, the streaming device can’t keep up – you will ‘finish’ watching the preloaded part before the next one had enough time to download, and your programme will STOP, until the device can fill the buffer again – i.e., download the next chunk.

Most Smart TVs and streaming boxes can connect to the internet via WiFi. WiFi’s been getting faster and more reliable in recent years – but its performance depends on a lot of factors.

The first issue is the location of your router (that’s the box connected to your broadband provider’s hole-in-the-wall – some providers call it “the hub”). If your router is in one room, and your telly is in a DIFFERENT room, the WiFi connection will deteriorate as it travels between the walls.

Sometimes, it’ll still be good enough – but if the rooms are on different floors, or if you have particularly thick walls – by the time the WiFi signal meets your TV or streamer, it might not be good enough for a fast, stable connection.

WiFi stability and speed can also be affected by the quality (and age) of your router, other airborne signals in and around your house, and even household electronics. So, you might have an incredible broadband package with a speed of 200Mb, but by the time it reaches your TV on the second floor, the poor thing only gets an equivalent of 20Mb

The solution? If your TV is really close to your router, you could always pull an Ethernet cable between the router and the TV – that’s actually the best, and fastest (in broadband terms) solution.

However, that’s not always a practical solution – if your TV is in a different room (let alone a different floor), you wouldn’t want to start pulling ugly cables throughout your house. That’s when a powerline adapter is the best solution.

What Is A Powerline Adapter?

In layman’s terms, a powerline adapter is a device that can send data via the power lines in your home. And since every house already comes equipped with electric wiring (Yes, even the cheap ones in Central London) and sockets throughout the house, it’s like having your own, super-long broadband extension lead.

For the powerline adapter to work, you always need two devices (all the starter kits reviewed here already come with two). The first adapter is connected to the power socket closest to your router. Then, you connect the powerline adapter to your router with a regular Ethernet cable (usually provided with your adapter).

Now, you take the second powerline adapter, and connect it to a power socket that is close to your TV. This time, you connect the adapter to your TV (or streamer) with a second Ethernet cable.

Of course, you can also connect the second adapter to a computer, or any other device that needs a wired internet connection. Plus, you can create a multiple-room network – by connecting A THIRD (and a fourth…) powerline adapter in another room, you will get another wired connection to use with another device.

Now, you just have to press a button on both devices at once, and… voila! Like magic, the two devices create a data network inside your walls, and your TV/Streamer now have their own, direct line into the internet – and to your favorite programmes.

Powerline Adapter Issues And Downsides

Even the best powerline adapters reviewed here have their issues, and are not always the perfect solution.

Since they depend on your electrical wiring, old houses with problematic wiring might pose problems, which you will only find out about once you actually connect your adapters.

In addition, just like with WiFi (but for different reasons), the data signal degrades over long distances. So if you live in Downton Abbey, you might have issues connecting the kitchen to the upper bedrooms… but even in regular homes, making the connection travel between different floors will lower the speed your TV is getting.

Additionally, powerline adapters should not be connected via lead extension cables or surge protectors, as that will hinder their performance – so you need an available, separate wall socket next to your TV. (Some of the best powerline adapters come with an electric pass-through, which means you can still use that socket for other devices as well).

And, of course, there’s the cord issue – after all, we’re cord cutters, so we don’t want cords running around the house, right? So yes, you do need an Ethernet cable running between your TV and the adapter. But if your socket is close enough, you can use a short cable, and that’s a decent price to pay for higher-quality streaming.

What Powerline Adapter Should I Buy – Things To Consider

With so many models, manufacturers and speeds out there, it might seem difficult to choose the powerline adapter that’s best for you. I’ve tried to simplify the process by listing five of the best, with different needs in mind.

Whichever model you eventually decide to buy, there are a few points you should take note of before you buy:

1. Powerline Adapter’s Speed

Powerline adapters come in many different speeds (that means the broadband speed your TV will actually get through the adapter). The older models had 200Mbps (that’s megaBITS per second, not megaBYTES), then 600 became common, and there’s 1000, 1200, and the newest one – 2,000Mbps.

Internet Speed meter

Since the point is to give your TV internet at good speeds, don’t bother with 500-600 ones – you should get, at the very least, a 1,000Mbps powerline adapter. Keep in mind, those numbers are theoretical – they represent the maximum “possible” bandwidth speed, but in real life, you will get much lower numbers.

Still, 1,000 is enough in most cases – even for streaming 4K video. If, however, you plan on connecting the adapter to more than one device at a time (or use another adapter in a different room), you should look into a higher data speed – 1200, or even 2,000.

Keep in mind that if at some point you decide to buy a third powerline adapter (for another TV, for example, or to connect a computer in a different room), the entire network will be as fast (or as slow) as your slowest adapter. So if you buy a 1000Mbps one now, and later buy a 2,000 one and connect it to the original one – you would still get 1,000.

2. HomePlug AV2 Standard

There are several companies that manufacture powerline adapters, but thankfully, there’s a standard that many of them follow.

The HomePlug AV2 Standard is a set of technical requirements and specifications for powerline adapters.

In addition to providing better support for high-speed connections, the standard also requires adapters to have an AES 128-bit encryption button – if you have neighbors who share your electrical wiring, encryption will stop them from “stealing” your data through your, well, walls.

Powerline adapters that carry the AV2 symbol are also inter-compatible, so if you wish to buy another powerline adapter in the future, and use it on the same network, you won’t have to buy the same model – but just one that also conforms to the AV2 standard.

3. How many ports do I need?

Some powerline adapters come with ONE Ethernet port, while others come with two (and even three). If you’re going to need to connect more than one device to your adapter, you should buy an adapter with two Ethernet ports. (For example – one to connect to your Smart TV, and a second one to connect to your Playstation 4).

4. Powerline Adapter With Passthrough or No Passthrough?

Remember, even the best powerline adapters need to be connected directly to the wall, without and extension leads. And if you have a shortage of wall sockets next to your TV or your router, you might end up with a missing socket once you connect the adapter.

For those cases, you can buy a powerline adapter with an integrated passthrough which you can use as a regular power socket, so nothing goes to waste.

Powerline Adapter VS. WiFi Range Extender

A WiFi range extender/booster is another solution for “spreading” your internet connection further around your house. An extender sits “in the middle” between your broadband router and the rest of the house, and “sends” the WiFi signal further away than what the router alone can do.

The pros? You don’t need to connect any additional cables around the house, and you don’t need to rely on your electrical wiring. But can it truly replace a good powerline adapter?

The answer depends on your situation and your needs. If your WiFi reception around the house is bad (that can happen due to a bad router, heavy walls, etc’) then a WiFi range extender may just spread that faulty WiFi around the house, without actually improving it.

Additionally, if you want to reach different floors in the same house – a range extender may not be powerful enough (though a WiFi mesh system might help in this case).

My suggestion? If you need a permanent, stable and fast connection, far from your router – go with a powerline adapter. For connecting multiple devices, especially when speed and stability are less crucial – a WiFi range extender can help. (And it also might be needed for WiFi-only devices like a WiFi smart plug)

See my list of the Best WiFi Range Extender and Boosters here.

Cord Busters’ Best Powerline Adapters 2019







  • Good price
  • Excellent performance and speed
  • Easy, plug-and-play pairing
  • Passthrough – saves you a socket


  • Power-saving feature can get too trigger-happy
  • Promised speed is questionable
  • A bit big – might block adjacent socket

Bottom Line

These do an excellent job, and at a very fair price. Installation is a breeze, just press the encryption button on both devices and you’re done. Performance is great, just remember that faulty or old electrical wiring can hinder your results. They’re not the cheapest powerline adapters out there, but you get excellent value from a known brand.

The speed is enough for most cord cutting scenarios (unless you’re connecting TWO 4K devices). There’s a similar model, the TL-PA9020PKIT, which is faster at 2,000Mbps – but it’s more expensive, so check your needs.

This is a fast and reliable powerline adapter – sure, there are faster ones out there, but they’re more expensive, and for a cord cutter looking to stream HD or 4K content on your TV, this is certainly enough.








  • Excellent performance and speed
  • Range+ technology
  • Easy configuration
  • Plug and Play pairing


  • Expensive
  • Rather big
  • Some buyers have reported disconnections

Bottom Line

Powerline adapters are not really a sexy gadget, and they shouldn’t be – you want to plug and forget about them. The Devolo dLAN certainly deliver on that – but they also add a “sexy” tech term on top – their “Range+” technology.

The Range+ technology uses all three wires in the power circuit, to – at least in theory – improve both the range and stability of the connection over longer ranges. It’s almost impossible to test, though, because the results (as with any Powerline Adapter) depend a lot on your specific situation – what the wiring is like in your house, what interference the devices might encounter, and how far you place them from each other.

Still, it’s refreshing to see some innovation in this “boring” – but important field.

Other than that, these are standard, reliable powerline adapters, with a passthrough socket and two Ethernet ports. They’re a bit pricey, but if you’re an Amazon Prime member, you can also go for the 1200+ model, which offers better value for money (but has only 1 Ethernet port).

TP-Link AV2000 TL-PA9020P Passthrough








  • Highest speed currently available
  • Improved performance over long distances
  • Two Ethernet ports and passthrough sockets


  • Expensive
  • Big and bulky
  • Led status lights on the side – difficult to see from afar

Bottom Line

If money’s not a factor, this is probably the best powerline adapter you can buy today. It’s twice as fast as all the other adapters, with 2,000Mbps, which means you can watch TWO 4K streams at the same time, with devices connected to both ports.

It has two Gigabit Ethernet ports,  an outlet passthrough, and promises to work better over long distances – though, keep in mind, this still depends on the quality of the electrical wiring in your house.

The problem? The price. It’s not only the fastest, it’s also one of the most expensive powerline adapters out there, and if you’re just looking for a quick an easy solution for your living room TV, this might be an overkill at that price.








  • Easy configuration
  • Good price


  • Only one Ethernet port
  • “Power-Saving” mode can be fussy
  • Questionable long-term build quality

Bottom Line

You don’t always have to spend a lot to get a decent, reliable device – and the Netgear PL1000 fits that bill.

As a wired powerline adapter, it’s not the best you can buy – it only has one Ethernet port, there’s no electric passthrough (though you can get a similar model that has one, for a little extra), and some customers reported failings after only weeks of usage, and some issues with the “Power Saving” mode that might be a bit too trigger-happy.

But if you’re looking for a cheapish device from a reputable company – the Netgear PL1000 is hard to beat.

Writer and news editor based in London, I cut the TV cord back in 2014 and never looked back. I watch A LOT of TV, and thankfully I can choose whatever I want to watch without depending on archaic channels.
