How to install a wireless doorbell

Updated: 16 October 2026

You have a button, a chime, and a door, and you would rather not open the consumer unit for a job that only needs a fixing and a socket you already have. This is how to install a wireless doorbell of the radio-chime kind: height, screws or tape, where the sounder sits, and the point where you stop. It is not a price ranking. Our [wireless doorbell comparison](/hub/electronic-surveillance/wireless-doorbell) is the table of eight amazon.co.uk kits. Products Compared editorial team, 15 October 2026. We did not time these fits in a lab. A qualifying purchase can earn us a commission at no extra cost to you.

Put the button where people can press it

Put the button where a caller can find it, off a metal door, at about 1.2 to 1.4 metres. Door Chimes UK puts the height there. A porch is the better face if you have one. A metal door skin and foil-backed insulation just behind the push are the surfaces these radio kits struggle with. A uPVC door can take a button if the skin is not metal and your tenancy allows a fixing. The order of those decisions is the wireless doorbell buying guide.

Tape only when the surface is smooth and dry

Use screws and wall plugs on brick, stone, or any exposed pier. Door Chimes UK prefers that, because adhesive lets go in a wet winter. Tape is reasonable on smooth, dry uPVC or painted timber if you accept that it may release in heat. The Wesstun tape did not stay on one hot exterior wall. The TK-WD005 listing says screws or tape, and one buyer returned it because there was no screw fixing. On the WA658, one buyer found no screw plate. If you rent, ask before you drill. A button still fails if the chime is the wrong side of a brick wall. That loss is on wireless doorbell range.

Put the chime where you will hear it

Plug a mains chime into a BS 1363 socket in the room where you actually sit, not beside the front door if you live at the back of the house. UK mains are 230 V. Do not force a two-pin block into a 13 A socket. Twin plug-in kits need two sockets. The kinetic TECKNET HDB01806 still needs a socket for the chime, and it gives that socket back through a pass-through so a lamp can stay plugged in. A battery chime does not need that socket. Byron's portable sounder, and the TECKNET packs with two or three battery receivers, can move to the landing or the garden. Pairing is in the manual. These kits are not an app.

Stop before the consumer unit

An existing socket is not a new circuit. Call an electrician for a transformer, a new spur, unknown cables, or anything inside the consumer unit. Extra-low-voltage bell wire, after a proper transformer, is a different job from mains. If you are not sure which wires you are looking at, stop. Do not connect old bell wires to mains, and do not stuff bare conductors into a socket. Do not replace a communal entry system with a button on the street door. If you rent and you cannot change the building bell, RNID points to a listener that hears the existing sound. The Consumer Rights Act 2015 is a shop question if the goods are faulty, not a reason to open a fuseboard.

Common questions

Where do I put the button?
About 1.2 to 1.4 metres up, where a caller can see it from the path, and off metal. A porch is kinder to the weather rating than an exposed pier. IP44 suits splashes. IP65 is dust-tight and protected against water jets. Neither code is a reason to leave the button in driving rain.
Should I use tape or screws?
Screws and wall plugs on brick or stone. Tape on smooth, dry uPVC or paint, if you can accept a pad that lets go. One Wesstun review lost the pad on a hot wall. One TK-WD005 buyer found no screw fixing. One WA658 buyer found no screw plate.
Where do I plug the chime in?
Into a BS 1363 socket in the room where you will hear it. Twin plug-in kits need two sockets. Battery chimes do not use a socket. The kinetic HDB01806 plugs in and has a pass-through. Do not use a two-pin adaptor as a permanent fix.
I rent. Do I need to drill?
Often you do not, if tape will hold on a smooth surface and the agreement allows it. Ask before you make a hole in brick, uPVC, or a communal door. If you cannot touch the building bell, a listener for the existing chime is the RNID point for renters.
What do I do with the old wired doorbell?
Identify the wires before you touch them. Old extra-low-voltage bell wire is not something you connect to 230 V. If you cannot tell bell wire from mains, stop and call an electrician. Do not push spare conductors into a socket. A wireless kit does not need those wires in order to ring.
When do I call an electrician?
Call one for a transformer, a new socket or spur, unknown cables, or any work at the consumer unit. Plugging a UK chime into a socket you already use is the job these kits are for. Communal door systems are also a stop. This page is not a certificate.
Can I fit this on a metal door?
You can stick a button to metal, and the signal may then fail. Radio chimes in this category are a poor match for a metal door skin, a metal frame tight around the push, or foil insulation directly behind it. Move the button onto timber, masonry, or a plastic surface beside the door if the agreement allows.
