Part P new socket: when to call an electrician

You have the back box, the face is still in the packet, and the question is whether this Part P new socket is a job you notify in England or a lead you should have left in the drawer. The answer follows the circuit and the room, not the colour of the plate. A new circuit is notifiable. Work in a bath or shower zone is notifiable. An extra socket on an existing circuit, outside those zones, is the case GOV.UK lists as often not notified. None of those sentences is a wiring diagram.

The England sources are the GOV.UK replacements note, the Building Regulations amendment in SI 2012/3119, Approved Document P, and Hampshire Building Control's note on domestic electrical work. The socket price is an amazon.co.uk listing in the surface-mounted socket comparison. We did not inspect a house.

In short

In England, a new circuit, a replacement consumer unit, and electrical work in a bath or shower zone are the notifiable jobs. Extra sockets on an existing circuit outside those zones are often not notified, and they are still electrical work. Scotland, Wales and Northern Ireland are not this note. A registered electrician can self-certify. This page will not tell you how to connect the socket.

Notifiable work in England

Part P is the electrical safety section of the Building Regulations in England. The list householders quote is the GOV.UK note on replacements and repairs: notify building control for a new circuit, for replacing a consumer unit, and for work around a bath or a shower. The 2012 amendment, which GOV.UK is summarising, puts the same triggers in the regulations, including an alteration in a special location.

A new circuit is the case people underestimate. If the socket needs its own cable back to the consumer unit, because the room was never on that circuit or the existing circuit should not take the load, you are adding a circuit, not just a face. That job is notifiable in England even in a dry bedroom with a plain UK 13 amp socket. Calling it a spur does not change the cable.

For this notification rule, special locations are the zones around baths and showers. A socket, a light or a USB plate in that room is the case to hand over. The note used here does not put an ordinary kitchen on that list, so this page will not invent a kitchen ban. Water near a sink is still a reason to keep leads out of the splash. That is a product warning, not a wider building-notice trigger.

A replacement consumer unit is the third trigger, and it is not a socket job. If the electrician says the board goes, the notification follows the board. This article will not describe fuses, breakers or how to test one. A new circuit to a detached garage is still a new circuit. A surface socket fed from a circuit that already serves the garage can be the other case. Describe the building, not the metal box.

Knightsbridge MR9000, the top-scoring row in the surface comparison, is a grey metal-clad 2-gang, 13 A, double pole claimed, BS 1363 claimed, £5.99, 4.5 from 475 reviews. It is a fitting. It is not a judgement about your garage circuit.

Work that is often not notified

GOV.UK lists extra socket outlets on an existing circuit, outside a bath or shower, among work that may not need notifying. Replacing a damaged socket with a similar one sits in the same family of repair. The cable has to be there, the circuit has to be able to take the point, and the room has to be outside the bath and shower zones. If any of those is false, you are back in the notifiable list, or in a job that should not be improvised.

May not need notifying is not a competence test. A job can be lawful without a notice and still be a bad idea if you have never worked on a ring or a radial. This page will not rank DIY skill and will not fill the gap with steps. If you are unsure the cable in the wall is the circuit you think it is, stop. Guessing which conductor is which is how a face gets energised while it is still off the wall.

A cracked face on a dry-room socket, swapped for another 13 A face of the same type, is the repair GOV.UK has in mind. A USB plate is a replacement only if the wiring is the arrangement the plate expects. A higher load, or a deeper box, can turn a repair into an alteration. Several surface sets in the comparison use a 25 mm box. A shallow box with too many conductors is a reason to let an electrician choose the box.

An extension lead avoids notification because nothing is fixed. Electrical Safety First would still rather you added sockets than lived on leads, fitted by a registered electrician. One device per socket, and a marked rating, are set out in choosing a UK extension lead. A lead through a window is not an outdoor socket. Fixed outdoor wiring is the installation.

Competent person schemes

England allows a registered electrician on a competent-person scheme to self-certify notifiable work. They tell building control, and you receive a certificate. Hampshire Building Control states the other door: if the person is not registered to self-certify, you submit a building notice before the work starts. Afterwards is the wrong order.

Ask whether they will self-certify this job, and which scheme they are on. A business card is not a scheme registration for domestic work. If they are not registered, building control sets the inspection. Paying cash with no paperwork is how a later sale stalls. Minor work that is not notified may not produce a building-regulations certificate, but it should still come with a receipt and a description of what was done. Many householders in the often-not-notified group still hire, because the saving is the notice fee and not the risk.

The fitting can be a surface socket or a flush one. Knightsbridge MR9000 sits first in that set, with a score reduction for contents ambiguity and high-load switch complaints on the listing. A certificate does not erase a review that says a switch failed. Choose the fitting with the electrician, and keep the BS 1363 claim in view. A badge on our page is an editorial ranking of listings, not a building-control approval.

What this page will not tell you to do

This page will not tell you how to open a consumer unit, identify a ring, spur a socket or change a fuse. If the job is notifiable, use a registered electrician or a building notice before anyone strips a cable. If it sits in the often-not-notified group, the same refusal stands. You can understand the category of the work without being given the method.

It will not apply the England list to the whole UK. The BS 1363 plug is UK-wide. Part P, as this GOV.UK page uses it, is England. In Scotland, Wales or Northern Ireland, use that nation's building rules. A reader in Belfast who follows an England often-not-notified line has used the wrong document.

It will not treat a product as a permit. A Wi-Fi plug from the Wi-Fi socket comparison is a plug-in device. It does not add a socket, and it does not need Part P because nothing is fixed. A USB plate is fixed wiring, so the notification question above still applies. A surface box in a packet is only a box until it is connected.

If you cannot say whether the cable is an existing circuit, whether the room is a bathroom, or whether the run is a new circuit to an outbuilding, you are already at the electrician. Knightsbridge MR9000 can wait in the packet until that person specifies it, or specifies something else. The plate is about £6. The circuit is the decision.
