Nuki's entry-level 5th-gen lock is officially Works with Home Assistant certified via Matter over Thread and clamps onto your existing key & knob cylinder with no drilling — ideal first smart lock for UK uPVC/composite doors, though multipoint doors need the handle lifted before it can throw the deadbolt. At £139 it sits between the Aqara U200 Lite (£128, not HA-certified) and Yale Linus L2 (£189, Matter over Wi-Fi). Unlike the pricier Nuki Pro (£229) and Ultra, the Go runs on 4 replaceable AA batteries with a single-speed brushed motor, and dedicated remote access costs extra rather than being included.

Officially Works with Home Assistant certified via Matter over Thread, the Pro (5th gen) uses the same retrofit-over-your-cylinder fitting as the £139 Go, but at £229 it swaps 4 AA batteries for a built-in rechargeable Li-ion pack that charges via USB-C in about 2 hours and lasts roughly 6 months per charge. The extra ~£90 also buys a Wi-Fi radio for Nuki's remote-access feature and, more usefully for HA users, a port for the optional Door Sensor accessory the Go lacks entirely. Worth it for fewer battery swaps and door-open/closed state; skip it if the Go's bare lock entity covers your needs.

At £249.99 with the Keypad Touch bundle, the Lock Ultra costs more than the Aqara U200 (£179.99) and Yale Linus L2 (£189.28) — the premium buys full local Bluetooth control with no hub required, plus a best-in-class keypad: up to 100 fingerprints, IP65-rated, and sub-second recognition reviewers praise. The lock body's 3×18350 battery pack claims ~9 months per charge, backed by a CR123A emergency cell and a supercapacitor for last-resort unlocks. Matter still needs a SwitchBot hub, so budget for one if you want Apple Home too. The EU/UK version fits euro profile cylinders out of the box, with a £19.99 adapter kit covering awkward thumbturns — check yours before buying.

Nuki's flagship, distinct from both Go and the Pro (5th gen): a brushless motor makes it the smallest (57 x 58mm) and roughly 3x faster Nuki lock yet, with built-in Wi-Fi needing no bridge for basic remote use. It runs on a built-in rechargeable battery rather than swappable cells — Nuki claims a 2-hour full charge either on the door or removed to a dock — a real trade-off against AA-powered rivals if you're away from home when it runs flat. Ships with an integrated universal euro-profile cylinder (separate Nordics and Swiss variants exist for those cylinder types). Officially Works with Home Assistant certified via Matter over Thread alongside Go and Pro — once paired over Matter you don't need a Nuki cloud account at all for day-to-day Home Assistant control.

The mid-tier step below Lock Ultra: SwitchBot's own listing explicitly confirms it fits European cylinders, British oval cylinders and Swiss round cylinders, with eight cylinder adaptors included in the box — no separate adapter purchase like the cheaper original Lock. The base Bluetooth model needs no hub at all for Home Assistant, since the official switchbot integration talks to it directly over local BLE; only Lock Ultra carries the full Works with Home Assistant badge, Lock Pro uses the same core integration but isn't separately certified. It sits meaningfully above the base Lock and below Ultra on price, and adds SwitchBot's own quieter/faster motor generation plus the persistent-calibration behaviour covered below.

Budget Matter-over-Thread lock that fits euro profile and UK oval cylinders (emergency function required) — a rare genuinely UK-door-friendly cheap option. It's a retrofit design: your existing cylinder stays put, so a physical key still opens the door from outside if the battery dies. No fingerprint reader or keypad at this tier — those live on the pricier U200/U300 — so unlocking is app, Bluetooth proximity, or the bundled NFC card, plus PIN codes via the separate Aqara Home app, not HA. The 2000mAh battery is rated ~6 months and charges over USB-C, no AAs. Local control via HA's Matter integration, but you'll need a Thread border router.

Not a front-door lock — it wires into an existing door-entry buzzer/intercom system (flats, apartment blocks) to trigger the electric strike remotely; wrong pick if your problem is actually a euro-cylinder front door. Runs on 4x AAA batteries (about a year) or permanent micro-USB power. The Opener itself only speaks Bluetooth — no built-in Wi-Fi — so the separate Nuki Bridge is mandatory for remote access and for the Home Assistant integration's Bridge HTTP API. Self-install is realistic via the Nuki app, but you're wiring into a shared intercom panel, so it suits confident DIYers more than total beginners.

At £122.75 the L2 costs roughly 16% more than the Aqara U200 Lite, and most of that premium buys polish rather than extra hardware — neither lock ships with a keypad or fingerprint reader. Yale's Smart Keypad (~£55) or fingerprint-capable Smart Keypad 2 (~£105+) are separate purchases, same as Aqara's approach. The bigger practical difference is backup access: the L2 has no physical key path by default, so budget for the optional Thumbturn Adapter or a compatible key-and-axle cylinder if you want one. It runs on a rechargeable Yale battery pack (~6 months per charge) rather than swappable AAs, and needs an emergency-function euro cylinder, same requirement as the Aqara.

SwitchBot's original, cheapest lock — the entry point below Lock Pro and Lock Ultra. It clips over an existing euro-cylinder thumbturn with adhesive mount and adaptors, no drilling. Bluetooth is the only radio built into the lock itself; a 2023 firmware update (Smart Lock firmware v6.5) added Matter support, but only when bridged through an optional SwitchBot Hub 2 or Hub Mini (Matter-enabled), for Apple Home, Alexa and Google Home. Home Assistant doesn't need any hub, though — the switchbot integration controls it directly over local Bluetooth. Runs on two CR123A batteries, rated ~180 days at ten cycles a day. Auto-lock re-engages on a configurable delay after the door closes. Oddly, Lock Pro sometimes undercuts this on Amazon UK, and Lock Ultra costs more than double via the direct store — buy this one only if you don't need Ultra's half-lock mode.

The best-value full-featured lock for UK doors: fits euro profile, select Scandi and UK oval cylinders, and it's a real step up from the U200 Lite (£128) — that extra £40-90 buys a bundled fingerprint keypad (25-print capacity, sub-0.3s recognition) plus Apple Home Key, neither of which the Lite offers. Matter over Thread gives fully local Home Assistant control, though only Home Key taps report a reliable unlock source. The lock body's 2000mAh Li-ion battery lasts ~6 months per charge; the exterior keypad runs on 4x AAA (or wired power) for similar longevity. Budget for a Thread border router if you don't already have one.

A credible euro-cylinder smart lock in the UK at around £236 — it clips over the thumbturn on any euro-profile cylinder with an emergency function, with an adapter for non-standard pins included in the box, so it suits most uPVC and composite doors. Power comes from three replaceable CR123 batteries rated for about six months, rather than the rechargeable pack Nuki's pricier Go offers. The tedee Bridge (~£67/€79, sold separately) unlocks HA's dedicated tedee integration and remote/cloud access, but it isn't your only local-control route: since firmware 2.1 tedee GO also speaks Matter over Thread, so it can join Home Assistant locally through HA's core Matter integration and a third-party Thread Border Router (Apple TV 4K, HomePod mini, etc.) with no tedee Bridge at all, and a community Bluetooth integration offers direct no-Bridge control too. No PIN keypad ships in the box either.

Launched in the UK in May 2026 alongside Aqara's Gate Lock and Glass Door Lock, this is a genuinely different UK door type from the U200 range: a surface-mounted rim lock (nightlatch-style) for classic UK entrance doors, rather than a euro-cylinder retrofit. Matter over Thread gives fully local Home Assistant control, same pattern as U200/U200 Lite, but you'll need a Matter controller and a Thread border router — and check the 40-45mm backset and drilling template against your door before ordering, since it's not a no-modification retrofit.

Dutch brand (now part of Shelly) built for euro-profile cylinders — but unlike most retrofit locks it ships with, and requires fitting, LOQED's own certified replacement cylinder rather than clipping over your existing one, so factor in that swap as installation friction. It doesn't support UK oval or Swiss round profiles. The payoff is one of the best Home Assistant stories in this category: the community-built but HA-core-bundled 'loqed' integration auto-discovers the included Bridge on your LAN and pushes state changes instantly over local webhook, no polling.

This isn't a modified Nuki — it's a genuine Nuki Smart Lock Pro paired with Ultion's own 3-star TS007 anti-snap cylinder and handle, aimed squarely at uPVC/composite multipoint doors over 55mm thick. The TS007 3-star rating (Ultion calls it '3 Star Plus') is the practical bit: most UK home insurers require it — or a 1-star cylinder plus 2-star handle — on final exit doors, so this closes an insurance gap a plain Nuki leaves open. That security buys the roughly £70 premium over the £229 Nuki Pro alone. Bundles vary by handle spacing (215mm/211mm/122mm) to match your existing multipoint mechanism, so measure before ordering.

Yale's current mid-range UK lock, distinct from the Linus L2 (which adds Wi-Fi/Matter) — this one is Bluetooth-only and fits the common UK 'lift-to-lock' euro-cylinder door, though Yale pushes you to its own compatibility checker rather than a blanket guarantee. The community yalexs_ble integration lists it by name, but be aware it's lock/unlock only with no live status feedback — a real but limited Home Assistant path. The older Conexis L1 has effectively been phased out of Yale's own UK range in favour of this model.

tedee's premium lock: a slimmer, quieter coreless motor and a built-in rechargeable battery instead of GO's 3x CR123A cells, plus native Apple Home support. It clips over a euro-profile cylinder with an emergency function (both keys turn simultaneously) — check yours has this before buying, since PRO's custom cam needs a tedee-ready cylinder or a locksmith-cut adapter, unlike GO's simpler drop-on fit. Amazon UK doesn't stock the lock body itself, only accessories, so buy from a UK security retailer; the official tedee integration gives genuine local-API control in Home Assistant once you add the separate Bridge.

This is a video doorbell and a smart lock welded into one faceplate, and in Home Assistant it behaves like exactly that split suggests: only the lock half shows up. The palm-vein unlocking, the 4-inch interior screen, and — critically — the 2K doorbell camera are all eufy-app/HomeBase territory that Matter simply doesn't carry over, so buying this expecting an HA camera entity alongside the lock will disappoint. It's a genuinely clever door unit if you want camera, doorbell and deadbolt in one purchase and are happy running the eufy app for that side, but as an HA smart lock specifically it's a one-trick pairing — you're paying for a lot of hardware that HA can't see.

The Airbnb host's favourite: clips over an existing euro-cylinder thumbturn with no drilling — a genuine DIY fit, not a locksmith job like igloohome's mortise lock — and generates offline, algorithm-based PIN codes that work with no internet or bridge, ideal for guest access. Runs on 4 AA batteries rated up to 12 months. Home Assistant support is official (added in HA 2025.2) but cloud-only: it needs an active iglooaccess subscription (around $2 USD per lock per month after a 30-day trial) plus the optional Wi-Fi Bridge for any remote or HA control, since Bluetooth alone can't reach the cloud API.

A genuinely different UK door type from the rest of this category: it replaces the mortise sashlock body itself rather than clipping over a euro-cylinder thumbturn — the right pick for a traditional mortise lock, not a cylinder. Installation is a locksmith job, not a DIY swap; check igloohome's compatibility chart against your mortise dimensions before buying. Runs on 8 AA batteries rated around 18 months, with a 9V backup terminal. Same offline PIN codes and official cloud 'igloohome' HA integration as the cheaper Retrofit Lock, but remote/HA control needs an iglooaccess subscription (around $2/lock/month after a 30-day trial) plus the Wi-Fi Bridge, on top of the £439.99 hardware price.
