Can You Fit a eufy Smart Lock on a UK Door?

• eufy's UK store, now on anker.com, listed no smart locks, and its UK smart-lock collection page returned an error
• eufy's lock range, in its Smart Display E10 compatibility sheet, includes the Smart Lock C210, C220, C33 and E30 and the Video Smart Lock E330 and S330
• eufy's lock pages cite BHMA, the North American standard, and JACK found no eufy lock listed as meeting BS 3621 or TS 007

• A door 35–55 mm thick, with a 60 or 70 mm backset from the edge to the centre of the lock
• A 38–54 mm cross-bore through the face of the door, plus a 25 mm hole into the edge
• uPVC and composite doors use a multipoint lock: a steel strip in the edge with hooks or bolts, thrown by the handle and locked by a euro cylinder. There is no cross-bore, and cutting one weakens the door and may affect its warranty
• Timber doors usually have a rim nightlatch and a BS 3621 five-lever mortice deadlock; a eufy lock means drilling a cross-bore and still leaves the deadlock question for your insurer

• Timber exit doors: a BS 3621 lock, typically a five-lever mortice deadlock
• uPVC and composite: a key-operated multipoint with at least three locking points; one UK policy wording adds a cylinder of at least five pins
• Many conditions say 'key-operated', so a keyless lock may not match them, while a retrofit that turns your existing key cylinder from inside is more likely to
• Euro cylinders can carry a TS 007 star rating against snapping, drilling and picking, and three stars in total is the usual target
• In that same insurer's set of wordings, one version removes theft cover and others raise the theft excess if the required locks are not in full use whenever the home is left empty

• The door must close itself and latch, and the lock, latch and hinges are fire-critical
• New holes or ironmongery are allowed only within what the door's fire test evidence permits, and a 38–54 mm cross-bore through the leaf is unlikely to be covered
• In blocks whose top storey is more than 11 m up, the Fire Safety (England) Regulations 2022 have the Responsible Person use best endeavours to check every flat entrance door at least once a year, and GOV.UK's guidance says a resident should change their front door only with the Responsible Person's knowledge and agreement
• A smart lock must never stop someone inside getting out in a fire

• uPVC and composite: a smart lock or retrofit made for euro-cylinder multipoint doors, matched to your handle, since lift-to-lock and slam-shut multipoints behave differently
• Timber: a smart lock designed for UK timber doors, with the BS 3621 mortice deadlock kept for your insurer
• Where the cylinder has no anti-snap rating, a TS 007 three-star cylinder on the same visit
• Set-up in the lock's own app, codes or keys for the household, and a test that the key still locks the door

• The whole door from outside and inside, so the material and the handle type show
• The door edge with the door open, showing the lock faceplate and any hooks or bolts along it
• The cylinder close up, with any star rating or BS mark visible, and the lock clause from your insurance schedule
• In a rented home, the landlord's agreement; in a flat, whether your door opens onto a common corridor, and the managing agent's reply

A vetted pro prices your job from the eufy model, photos of where each device goes and what power is there now, and the JACK app shows you that fixed price before you book.

The power and the walls move the price more than the device does. A battery doorbell on a brick reveal, or a SoloCam on a fence post, is a smaller job. An S4 Wired doorbell on a new transformer, a HomeBase moved to the middle of the house with a hard drive fitted, a Floodlight Camera E340 in place of an outside light, or four PoE cameras cabled through solid brick and a loft all take longer, and the price reflects that.

The eufy kit is yours to buy, since JACK sells no devices. A stronger transformer, a Chime 2, a wedge, a floodlight's weatherproof box or extra Cat cable is agreed with you and added at cost before you book, and several devices go on one booking for one price. Where parking has to be paid for, that is added at cost and agreed before you book too.

Prefer to pay for time? As a guide, smart home work is typically £45–£95 per hour, and electrical work such as a floodlight camera £55–£110 per hour. For a multi-camera system or a PoE NVR, a full-day booking is a flat £350–£400 for up to 8 hours on site.
