Do you need an electrician to install CCTV? (UK guide)

The short answer

For most home CCTV you don't strictly need a qualified electrician, because the cameras themselves run on low voltage and are wired by the CCTV installer, not mains-connected directly. A specialist CCTV installer handles the cameras, cabling and recorder. An electrician becomes involved when new mains power is needed — for example a new socket or fused spur for the recorder or a power supply — or when the work touches the consumer unit. New fixed mains wiring is notifiable under Part P of the Building Regulations in England and Wales and should be done by a competent person. Many CCTV installers either include this or work with an electrician for the mains side. This is general UK guidance.

CCTV is mostly low-voltage work, but the answer depends on whether new mains power is needed. The points below are general UK guidance.

Why most CCTV doesn't need an electrician

The reason CCTV usually isn't electrician's work is that the cameras run on low voltage, typically 12 volts DC or via Power over Ethernet (PoE) on IP systems, not on 230-volt mains. The mains-powered part is the recorder and the power supply unit, which plug into a standard socket like any other appliance. From there, the power to the cameras is stepped down to low voltage and carried along the CCTV cabling. Running and connecting that low-voltage cabling is the core skill of a CCTV installer, and it doesn't require an electrician's qualifications.

So for a typical install — cameras wired back to a recorder that plugs into an existing socket — a competent CCTV installer does the whole job. They mount the cameras, run the low-voltage cabling, fit the recorder, plug it in and configure the system. No new mains wiring is created, nothing connects directly to the consumer unit, and the work sits outside the parts of the electrical regulations that require a qualified electrician. This covers the majority of home CCTV installs, which is why most people never need a separate electrician at all.

This is also true of DIY and wireless systems. A plug-in Wi-Fi camera or a self-fit kit powered from existing sockets involves no mains wiring work, so there's nothing for an electrician to do. The cameras and recorder simply use power points that are already there. As long as you're using existing sockets and not altering the fixed wiring, the electrical side is no more complex than plugging in any other device, and the skill needed is in the cabling and configuration, not the electrics.

When an electrician is needed

An electrician comes into the picture when the install requires new or altered mains wiring. The most common trigger is needing power where there isn't a convenient socket — for the recorder, for a camera power supply, or for a camera in an outbuilding or remote position. Adding a new socket, a fused spur, or a new circuit is fixed electrical work, and in England and Wales this is governed by Part P of the Building Regulations. Part P makes certain electrical work in dwellings notifiable, meaning it must either be done by an electrician registered with a competent person scheme (who can self-certify it) or be notified to and signed off by building control.

Any work that touches the consumer unit (fuse board) — adding a new circuit or a protective device — is firmly electrician's territory and should never be attempted as DIY. The same applies to running a new mains supply to a detached garage or outbuilding to power cameras there, which involves a sub-main and is notifiable, more complex work. In these situations you need a qualified electrician, ideally one registered with a scheme such as NICEIC, NAPIT or ELECSA, so the work is certified and compliant.

The practical upshot is that the question isn't really 'CCTV installer or electrician?' but 'does this job create new mains power?'. If it does, an electrician handles that part; if it doesn't, the CCTV installer covers everything. Many CCTV installers either hold the relevant electrical qualifications themselves or partner with an electrician, so they can deliver a complete job including any mains work needed — worth asking when you get the work priced up, so you know the mains side is covered and certified.

Worth knowing: the dividing line is mains power, not the cameras. Cameras are low voltage and don't need an electrician — but adding a socket, fused spur or anything touching the fuse board is notifiable work for a qualified electrician under Part P.

Part P, certification and choosing who does the work

It helps to understand Part P of the Building Regulations, which applies in England and Wales (Scotland and Northern Ireland have their own equivalent rules). Part P exists to make sure fixed electrical work in homes is safe. Not all electrical work is notifiable — minor jobs like adding a fused connection unit on an existing circuit may not be — but installing a new circuit or working in higher-risk areas is. The simplest way to comply is to use an electrician registered with a competent person scheme (such as NICEIC, NAPIT or ELECSA), who can carry out and self-certify the work and provide the certificate, without a separate building control application.

That certificate matters. It's your evidence that any mains work was done to standard, which is useful for insurance, for safety, and if you ever sell the house and a buyer's survey asks about electrical work. For the CCTV side, while there's no equivalent legal certification scheme for the low-voltage installation, using an installer registered with a recognised body — such as the NSI or SSAIB, or one vetted through a platform like Checkatrade — gives confidence the cameras are fitted and configured competently. The two sit alongside each other: electrical certification for any mains work, and a reputable installer for the CCTV itself.

When choosing who does the work, the cleanest approach for most homeowners is to use a CCTV company that can handle the whole job — including arranging or carrying out any mains power work through a qualified electrician — so you get one accountable point of contact and the right certification for the mains side. If you're doing a simpler install that plugs into existing sockets, a CCTV installer alone is enough, and a confident DIYer can manage a wireless or plug-in system themselves. The key check is always whether new mains wiring is involved; if it is, make sure a qualified, registered electrician does that part.

Frequently asked questions

Is CCTV mains voltage or low voltage?

The cameras run on low voltage — typically 12V DC or Power over Ethernet — not 230V mains. Only the recorder and power supply plug into the mains, like an ordinary appliance. That's why a CCTV installer, rather than an electrician, normally does the camera wiring.

Do I need an electrician if the recorder plugs into an existing socket?

No. If the recorder and power supply use a socket that's already there, no new mains wiring is created, so there's nothing for an electrician to do. A CCTV installer can complete the whole job. An electrician is only needed if you have to add a new socket, fused spur or circuit.

Is adding a socket for CCTV notifiable under Part P?

Adding a new circuit is notifiable under Part P in England and Wales, and any work touching the consumer unit must be done by a qualified electrician. Using an electrician registered with a competent person scheme (NICEIC, NAPIT or ELECSA) lets them certify the work without a separate building control application.
