The Best Smart Locks for uPVC External Doors With Multi-Point Locks in the UK
I originally wrote this post back in 2021, when my top recommendation was the Yale Linus Smart Lock. It was a great lock at the time, but not something I would recommend now, and it has been superseded by the Yale Linus Smart Lock L2.
In the years since, a lot of amazing options have launched, and this post is long overdue for an update.
When I originally wrote the post, the smart lock market was still in its infancy, relatively speaking, and searching on Google for the best smart locks in the UK revealed a lot of poor advice that was not tailored to the UK market.
In the past, most smart lock guides seemed to point you toward the August Smart Lock Pro as their top choice. However, this is not designed for the UK market. It may be an excellent lock, but it is designed for US doors with a single deadbolt, whereas the typical UK uPVC external door uses a more secure multi-point locking mechanism.
Times have changed, with a large number of multi-point compatible smart locks available on the market. But Google searches are still misleading.
One of the main issues is that major publications have US and UK versions, but their reviews don’t factor in regional differences. They only care if a product is listed on Amazon. For example, PCMag UK lists the August Smart Lock Pro + Connect as one of their top choices, but the review is written by an author based in the US and quotes USD prices. All the other recommendations on their list appear to be catered for the US market. The content is just duplicated from the US version of the website. This isn’t entirely a criticism of PCMag; the logistics of having UK and US-specific content are quite hard.
So, this list is my options for the best UK-specific locks that will work on uPVC external doors that have multi-point locks with a Euro cylinder (most of them are compatible with other cylinders too).
That seems like a very niche list, but it’s literally what most of the UK uses (excluding flats).
Ultion Nuki or Nuki Smart Lock Pro 5th Gen
I have reviewed both the Ultion Nuki and Nuki Smart Lock Pro 5th Gen in the past year and love them. I use the Nuki on my back door and the Ultion on my front door.
They are essentially the same lock, but the Ultion includes a special door handle that the Nuki mounts to, creating a more visually appealing installation while also being significantly easier to fit.
If you have a door that requires the style of handle Ultion provides, then I would strongly recommend it. I think the door handle is well worth the £100 premium you pay. Ultion also includes a Ultion 3-star PLUS cylinder, which should fit most doors and is a special high security cylinder with a £5,000 security guarantee
The reason why I love the underlying Nuki lock is that it just works well. I have had no jams or need to recalibrate it; the battery life is superb, and I have found the fingerprint scanner and keypad to be excellent as well.
To top it off, for connectivity, you have either WiFI or Thread with Matter support, so I was easily able to integrate this with my Home Assistant installation.
It is possible this is one of my favourite pieces of tech; I have no significant criticisms of it at all, it just does its job without causing me any stress.
Aqara Smart Lock U200
- [Native Matter Support over Thread] The Aqara Smart Lock U200 seamlessly integrates with the robust Matter platform and is compatible with Apple Home, Google Home, Amazon Alexa, Samsung SmartThings, and Aqara Home. With the Aqara Hub M3, you can enable the remote unlock feature and set up automations with other devices within the Aqara Home app. *U200 is currently compatible with the Aqara M3 hub and Camera Hub G5 Pro but not with other Aqara Zigbee hubs; for compatibility with other ecosystems, please refer to the list of 2-in-1 Matter Controllers and Thread Border Routers.
- [Apple Home Key] The U200 offers a variety of convenient unlocking methods, such as Apple Home Keys (Apple 2-in-1 Matter controller & Border Router required), fingerprint (Maximum 25), password, NFC (not included and only supports Aqara NFC card), and more. You can also control the door lock using the app, either via integrated Bluetooth or through Thread for remote access. Additionally, it supports temporary passwords, including one-time passwords and periodic passwords for easy sharing with others, and it also supports mechanical keys for emergency situations. (Tips: After adding the door lock to the Aqara Home app, only the administrator's fingerprint or password can reset the door lock.)
- [Wide Compatibility & Easy Installation] The U200 is compatible with Euro profiles, select Scandi cylinders, and UK Oval Cylinders. And please ensure your lock supports emergency functions, with a key thickness ≤ 5mm and handle length ≤ 39mm. The lock is designed for hassle-free installation, fitting over the existing door lock without any drilling or screwing required, making it a convenient and straightforward solution for enhancing home security.
- [Rechargeable Battery & Multi-Power Options] The lock of the U200 is powered by rechargeable Li-Ion batteries with a battery life of up to 6 months( Performance based on up to 8 daily unlocking and locking actions via fingerprint/NFC), ensuring extended performance, and the keypad accommodates 1.5V AAA batteries and offers hard-wired powering capabilities*. It operates flawlessly in extreme temperatures ranging from -15 °C to 66 °C and the keypad is IPX5-rated for outdoor usage. (* AAA batteries are not rechargeable, and a hardwired setup requires a 12V-24V AC or DC power supply.)
- [Quiet Unlock Mode & Auto Lock] The U200 comes with Quiet Unlock Mode, enabling you to unlock the door slowly, effectively reducing noise levels. Activate this feature right from the keypad: it's a standalone setting that doesn't require a hub or a Thread border router. Additionally, thanks to the built-in gyroscope, the U200 can remind you if the door is left open and even automatically lock it after closure. (This feature can only be used in the Aqara Home app, and please make sure the firmware for the Aqara Home App has been updated to the latest version.)
This may be a controversial choice, as I have read quite a lot of reports of people having issues with the Aqara Smart Lock U200. There have been many reported mechanical issues. However, my personal experience was that it is superb and not far behind the Nuki I have recommended for the overall experience.
Battery life was excellent, it unlocked reliably, and the fingerprint scanner and keypad worked well (but not as well as Nuki).
Even though I am putting this in 2nd place based on my personal experience, I’d approach it with caution and perhaps only buy it if there is a deep discount to make it worth it.
At the time of writing, this was £180 and includes a fingerprint scanner, making it significantly cheaper than the Nuki.
SwitchBot Lock Ultra Vision Combo
- Facial Recognition Unlock: Unlocks automatically as you approach, no keys or fingerprints needed. Works seamlessly even when your hands are full, wet from the rain, or in low-light conditions. (Recognition range: 0.6 to 0.9 meters, Height coverage: 1.2 to 2 meters)
- Secure Local Facial Recognition: Powered by financial-grade 3D structured light technology with a false recognition rate of less than 0.0001%*. All facial data is processed and stored locally—never uploaded to the cloud—for enhanced privacy and peace of mind.
- Triple Power Protection: Enjoy up to 9 months of battery life with the main battery, backed by a backup battery, and an emergency supercapacitor. Works even in extreme cold down to –40°C. When charging the main battery, the backup seamlessly takes over. Even if both run out, you can still unlock the door using emergency microcurrent power. No more lockout worries.
- Sleek, Drill-Free Installation for Any Lock: Sleek all-metal body, now 50% slimmer. Features magnetic quick-release design and seamless base ring for gap-free installation—no drilling required, no damage to your existing lock. Includes 3 wood grain finish stickers to match different home styles. Optional accessory kit adapts to 99% of non-standard locks (sold separately).
- Multiple Unlocking Methods: In addition to the innovative facial recognition, the SwitchBot Lock Ultra Vision Combo also supports fingerprint, password, voice commands, Apple Watch, and remote unlocking via the app. This set includes the Matter-compatible Hub Mini, compatible with third-party platforms such as HomeKit, Alexa, and Google.
On paper, the SwitchBot Lock Ultra Vision Combo should be the best smart lock. It is arguably the most advanced option with some impressive features, including:
- A 3-tier battery system to reduce the risk of being locked out. You have the main battery with up to 9 months of battery, a CR123A backup battery with a 5-year battery life capable of 500 unlocks, and then a last resort micro-electric system capable of 5 emergency unlocks.
- Then, for the keypad, it has a fingerprint scanner, a keypad and facial recognition
- It also includes Matter and Home Assistant support and can integrate with other Switchbot devices for more complex automations.
I found it a good lock and used it for several months, but it had a few quirks that may be the result of a poor installation on my part. Every couple of months, I needed to recalibrate it. Normally, the door wouldn’t lock properly, so I’d need to take a key with me and recalibrate it when I got home. I also found the facial recognition was not great, but I may have mounted it at a sub-optimal height.
The lock is well reviewed on Amazon, much better than the Aqara, so I think some of my issues were user error or just bad luck.
At the time of writing, it is just £240, which is a lot of tech for the price and much better value for money than the Nuki/Ultion.
ERA Protect Smart Universal Door Handle
I have mixed feelings about the ERA Protect Smart Universal Door Handle. Unlike my other recommendations, this isn’t a smart key turner like the above recommendations. It replaces all the hardware, and you can then unlock it with your fingerprint, NFC card or via the app.
I am not a huge fan of smart locks that don’t offer a backup option like a mechanical key, and I think many people feel the same.
On this, if the battery dies, there are two contact points that allow you to use a 5V battery for backup.
One of the benefits of this lock is that it fits certain doors that the above options don’t work on. I mounted it on my garage/gym doors, which are outward-opening French doors. Because they open outward, the previous options don’t work because they catch on the second door, which isn’t a problem with the ERA.
I still use the ERA, but unfortunately, I have found the battery to be very poor; it lasted a few months, then died. Cheap replacement AA batteries lasted at most a few weeks.
We.lock Smart Lock Review [SOHO-EU]
I also had mixed feelings about this We.lock Smart Lock. Similar to the ERA, I am not overly keen on locks without a mechanical backup. I also found the keypad difficult to use and made worse by the display being unreadable in sunlight.
However, like the ERA, it fitted my bifold doors when other locks didn’t work with it.
Most importantly, it worked surprisingly reliably, and I used it for three years in my garage before replacing it with my ERA. I had absolutely no issues with the battery life, I think I may have replaced them once or twice during the time I used it.
It is also reasonably priced at around £130, so I think it is a decent option if you are on a budget, and I think it is well-suited for less important doors like a shed/garage/back door.
There are also fingerprint options, which perform reasonably well (I’d prefer a fingerprint lock to include a keypad as well, though).
Previous recommendations which are out of date
I am leaving my old recommendations in place for prosperity, more for myself than for readers. I no longer recommend any of the below, not because they are bad, but newer models are available which are superior.
Yale Linus Smart Lock
Related: Yale Linus Smart Lock Review
As previously mentioned, most other guides recommend August, and the Yale Linus Smart Lock is the closest you will get.
This is the lock I personally use on my front door; I have had it there since the start of this year (2021) and had no major problems with it at all.
This lock and others on the list are more of a smart cylinder/key turner than an actual lock. You can mount it over your existing key/thumb turn or replace the entire cylinder with a specially designed adjustable cylinder. This will then open or close the lock.
The major advantage of this design is that you can continue using your mechanical key on the other side of the door. So, it acts as a sort of hybrid smart lock, which alleviates some of the concerns people have about full smart locking systems.
The minor negatives I have about this are:
- Bluetooth connectivity is a little slow, so unlocking with a phone or keypad can take a few seconds
- It is kind of ugly. For most/all uPVC UK doors, the handle extends down to cover the lock. So Linus needs to sit on top of this. It has screws that lock it in place securely, but it is not quite as aesthetic as sitting flush on your door.
- More expensive than others when you factor in the cost of the £70 Connect Wi-Fi Bridge
Ultion Smart Lock
Related: Ultion Smart Lock Review
I reviewed the Ultion Smart Lock in July last year and have used it on my back door since it is another lock I can personally vouch for, and it has worked well long term.
This is technically just a Danalock V3 that has been fully integrated into the hardware. So, the overall installation is more aesthetically pleasing on the inside than the Yale Linus Smart Lock.
It works sort of the same; all the electronics turn the cylinder. However, in this case, Ultion also supplies their own cylinder, which uses one of their fancy high-security keys, which come with a £2000 security guarantee.
At £259, considering you get door handles and a high-security key, this is well priced vs the Yale.
The negatives I have on this one are:
- French doors would end up with mismatched hardware unless you replace both locks
- The Samsung SmartThings connectivity seems to be intermittent, certainly not as good as the Yale connected bridge. However, it is extremely rare that I have remotely connected to my lock.
Not really a negative or positive, but you have the option for a Bluetooth model or Apple HomeKit, but not both at the same time.
Nuki Smart Lock
Related: Nuki Smart Lock Review
In terms of functionality, this is basically identical to the Yale Linus Smart Lock. It sits over existing hardware and turns the locking mechanism.
It is cheaper than the Yale Linus, and they have more accessories, including a keypad, rechargeable power pack, a key fob and even a keypad/fingerprint scanner. The fingerprint scanner is only IP54 rated, though, so not ideal for outdoor use in exposed conditions (considering the UK weather).
So, for some, it may be a better buy than Yale, but the few negatives I have for it meant Yale was better for me, personally.
- This also needs to mount on top of your door handle (if that’s your door design), but the backplate doesn’t secure in place as well as the Yale
- The plastic build quality isn’t as good as the Yale
Yale Conexis L1 Smart Lock
![Yale Conexis L1 Smart Keyless Door Lock for Home Security, Remote Lock/Unlock, App Control, Key Card and Phone Tag Included, Chrome Finish [BSI Approved], SD-L1000-CH](https://m.media-amazon.com/images/I/214UIIFjTDL._SL160_.jpg)
Related: Yale Conexis L1 Smart Lock
One of the original smart locks on the market, and to some extent, the smartest of them all. This replaces everything and gets rid of your keys while it is at it. So, it is fully smart.
This gives you the option of unlocking via your phone, or alternatively, you can use NFC tags. These come in the form of cards, key tags or a phone tag you stick on the back of your phone/case.
The NFC functionality makes the unlocking experience a little more seamless than Bluetooth connectivity. It just feels smarter.
This will also integrate with Yale smart alarms or Z-Wave systems.
You get a lot of hardware for your money with the Yale Conexis L1, it is cheaper than all the other options.
Negatives include:
- Installation is much more complex than the relatively easy Linus – though I still managed it myself, and I am awful at DIY
- If the battery dies, the battery backup option is far less convenient than using an old fashioned key
- Anxiety over possible failure. Even if this is unlikely to happen, it is a common concern for many people.
- French doors end up with mismatched hardware
- I can spot a house using a Conexis L1 a mile off. I feel like this could be more tempting for burglars with the household more willing to invest in expensive electronics (this could be a highly inaccurate assumption by me)
Netatmo Smart Door Lock
The Netatmo Smart Door Lock is a fully integrated smart cylinder; it doesn’t sit on top of your key/thumb turn, but it doesn’t replace your hardware either.
While it does use keys, these are just cosmetic, and they are actually NFC key tags, so it is most closely matched to the Yale Conexis L1.
The Netatmo Smart Door Lock was announced at the start of 2020 with a launch date in late 2020, but there is still no sign of it. It has a much higher price tag than competing options, too. The COVID pandemic has probably delayed things, but with no word about it in over a year, I am starting to wonder if they will ever launch it.
