Smart home locks are no longer just a luxury for tech enthusiasts — they’ve become a vital tool for homeowners who value convenience, control, and enhanced security. At the leading edge of this evolution is the Ultion Nuki Plus, a next-generation smart lock that pairs the mechanical strength of Ultion with the digital capabilities of Nuki’s Smart Lock Pro.
At County Secure, we understand that homeowners across Surrey are looking for reliable, intelligent ways to protect their properties without complicating their daily routines. That’s why we proudly recommend and install Ultion smart locks.
In this guide, we take a closer look at what makes the Ultion Nuki range so effective, how these locks fit into modern lifestyles, and why our team recommends them for homeowners and holiday property owners across Surrey.
What Is the Ultion Nuki Plus?
The Ultion Nuki Plus combines two powerful components: the Ultion 3 Star Plus security cylinder and the Nuki Smart Lock Pro. Together, they offer a secure, app-controlled entry system that can be managed remotely.
Unlike many smart locks, which rely solely on technology for enhanced security, the Ultion Nuki range maintains the high standard of physical protection Ultion is known for.
This system doesn’t replace your traditional key entirely — it enhances it. You keep the strength of a mechanically robust Ultion lock while gaining full access to smart features like remote locking, auto-unlock, and digital access management.
Key Features of the Ultion Nuki and Nuki Plus
Control is at the heart of the Ultion Nuki experience. With the Nuki app, you can lock or unlock your front door from anywhere in the world — whether you’re at work, on holiday, or just want to check if you secured the door after leaving the house.
The auto-unlock feature detects when you’re approaching and opens the door hands-free. This is particularly useful when arriving home laden down with shopping and children, or in poor weather.
You can also share timed access with others, so guests, cleaners, or tradespeople can enter without needing a physical key. Once their access period ends, their digital permissions are revoked automatically.
You’ll receive real-time status updates and activity logs through the app, offering a complete picture of who’s entered and when. If the door is left unlocked or someone tries to force entry, you’re instantly notified.
The Security Power of Ultion
While smart features are a draw, security remains the foundation. Ultion locks are widely recognised as some of the most secure locks available in the UK today. With a TS007 Kitemarked 3-star cylinder, BSI Kitemark for IoT security, and Sold Secure Diamond rating, each lock is built to withstand forced entry attempts like snapping, drilling, or bumping.
A standout feature is Lockdown Mode — a hardened core that activates if an attack is detected, preventing the lock from turning. This physical security ensures that even if smart systems fail, your home remains protected.
Ultion’s reputation among locksmiths and insurers speaks volumes. Unlike cheaper smart locks that trade durability for tech features, Ultion door locks bring both together in a way that homeowners can trust.
Smart Home Integration and Voice Control
The Ultion Nuki system is designed to integrate seamlessly with smart home ecosystems. It works with Amazon Alexa, Google Assistant, and Apple HomeKit, allowing you to lock and unlock your door using voice commands or automate routines that include your front door.
For example, you can create a morning routine that turns on your lights, adjusts your thermostat, and unlocks the door — all hands-free. These features are especially useful for busy families or homeowners with accessibility needs.
The Nuki app also supports smart notifications and status checks, meaning you can confirm whether your door is locked without leaving the sofa.
Why the Ultion Nuki Plus Is Ideal for Holiday Lets and Airbnb Hosts
For holiday property owners and Airbnb hosts, the Ultion Nuki Plus offers an elegant solution to some common headaches. Instead of arranging key handovers or worrying about lost copies, you can issue digital keys to guests in seconds — and revoke them the moment they check out.
Guests benefit from a smoother experience with self-check-in and flexible arrival times, while hosts can relax knowing there’s no risk of keys being misplaced, duplicated, or forgotten. For those managing multiple properties or remote sites, the ability to control and monitor access from a single app is invaluable.
Is a Smart Door Lock Really Worth the Investment?
The short answer is yes — especially when it comes to the Ultion Nuki Plus. It’s more than just a gadget; it’s a practical tool that delivers long-term value.
Having received glowing reviews from everyone from the Federation of Master Builders to Stuff and Tech Radar, there are many reasons it is often hailed as the best smart lock on the UK market.
From a security perspective, it removes the risks associated with lost or copied keys. From a lifestyle perspective, it simplifies daily routines and enhances access control. And when it comes to financial benefits, smart upgrades like this can increase your property’s value and appeal to future buyers or tenants who prioritise convenience and modern features.
Whether you’re a tech enthusiast or just looking for a safer, smarter way to manage your front door, the Ultion Nuki range represents a sound investment in both security and quality of life.
