What Decides the Cost of eufy Installation in London

• A C30, or an E340 or C31 left on battery: fixing at about 1.2 m, a 2.4 GHz Wi-Fi check and pairing a chime
• An E340 wired to the existing bell: the transformer must give 8–24 V and more than 10 VA, or a new one is added
• A C31 set up for 24/7 recording: a 16–24 V, 30 VA transformer, the old chime bypassed and a plug-in chime added
• An S4 Wired Video Doorbell, which has no battery mode: many British bell transformers fall short of its 16–24 VAC, so a new transformer is often part of the price

• Siting the HomeBase on Ethernet by the router, with each camera inside eufy's range and wall limits
• Camera count and height: eufy puts eufyCam S3 Pro cameras 2–3 m up, so a 4-camera kit is four ladder positions to test and fix
• Sun: on a north-facing wall or under deep eaves, an external solar panel and its cable may need routing; eufy advises the external panel under eaves
• Storage: fitting a 5 V 2.5-inch SATA drive in a HomeBase S380 and formatting it in the app
• Walls: solid brick takes longer to drill than timber cladding, and render that has come away from the brick needs longer fixings that reach solid masonry

• The S4 Max box holds an 8-port NVR with a 2 TB drive fitted, four PoE cameras and four 18 m Ethernet cables, so longer runs need extra cable
• Each run goes through the loft, along an outside wall or through solid brick, and its length and route drive the price
• The recorder itself lives indoors, by a socket, with its own cable to the router, and can show the cameras on a TV over HDMI

• It goes where an outside light is now, on that light's circuit, wired at 100–240 V AC
• The earth is proved and any dimmer or timer comes off the supply, as eufy's guide asks, along with any separate PIR switch that would cut the camera's power
• eufy's box has no junction box, so a weatherproof enclosure is added at cost where the old light has none
• Where the wall has no light and no cable to it, a new circuit may be needed, and that goes to a registered electrician, as JACK does not book it

• Taking down an old system first, or moving older eufyCams onto a new HomeBase
• Flats and listed buildings: written consent from the freeholder, landlord or council before any drilling
• Getting in and up: stairs, a lift or a locked side passage. Paid parking is added at cost and agreed before you book
• Parts: a transformer, chime, wedge, drive, microSD card, extra Ethernet cable or junction box, all agreed and added at cost before you book

• A photo of each mounting spot taken from a few steps back, so the height and the ground below show
• Doorbell jobs: the front door and frame, the label on the bell transformer, and the chime
• For HomeBase cameras, where the router is; for an NVR, where the recorder will live and the route each cable could take
• The eufy models, from the box or the order

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.
