We all like to save a few quid by doing a bit of DIY around the home rather than paying

someone to do it. However, most people will not attempt DIY on anything to do electricity

for obvious reasons! As well as the worry of fire or electrical shock you also have to

involve Building Control for most electrical work.

I’m probably shooting myself in the foot here but there are, however, a few electrical jobs

you can attempt safely yourself without getting the authorities involved. This month’s

Circuit Shorts is dedicated to clarifying which electrical jobs you can attempt yourself and

which ones are best left to us professionals!

Since 2005, all domestic electrical work in England and Wales whether carried out

professionally or as DIY, must comply with Part P of the Building Regulations

(www.electrical.theiet.org/building-regulations/part-p/faqs.cfm) or you could be asked

to remove it, put it right or even fined up to £5,000. It could also make it difficult to sell your

property in the future. In April 2013 the requirements for England were amended, see

clarification of the amendments at http://electrical.theiet.org/wiring-matters/51/part-p-

certification/index.cfm.

For most electrical work you will need to notify your Local Authority Building Control

Department office (BEFORE you begin the work) in order that they may inspect the work

during construction and upon completion. It is a bit of an electrical quagmire out there so I

have listed below, in a nutshell, the kind of work which is and is not notifiable. I would

suggest contacting your local authority before you undertake ANY work to be on the safe

side.

Notifiable or non-notifiable?

Non-notifiable

You don’t need to notify your Local Authority if you do minor electrical work such as:-

replacing or repairing a socket, light or cable in any room;

adding extra spurs, sockets or lights to an existing circuit (except outdoors or in

a special location*); or

installing security lighting or air conditioning to the outside wall of a house, provided

that there are no exposed outdoor connections (unless a new circuit is needed).

However, the work must be done to the standards in the Wiring Regulations and you

should consider having the work checked by a competent electrician to make sure it is

safe.

Notifiable

You will need to notify to your Local Authority Building Control Department office where

the work includes:

the installation of a new circuit, whether at low voltage (typically 230 V) or extra-low

voltage);

the replacement of a consumer unit (fuseboard); or

any alteration or addition to an existing circuit outdoors or in a special location*,

whether at low voltage (typically 230 V) or extra-low voltage.

An alteration or addition to an existing circuit in a room containing a bath or shower is

notifiable only where carried out in the space surrounding a bath or shower.

An alteration or addition anywhere within a room containing a swimming pool or sauna

heater is notifiable.

*A special location is a room containing a bath or shower, swimming pool or a sauna

heater.

We at S W Bishop Electrical would, however, strongly recommend that any of the above

works should be carried out by a Part P qualified electrician and we would NEVER

recommend carrying out electrical work in a bathroom, kitchen, utility room or outside

unless you are a qualified electrician.

Competent Persons Register

The UK Government has recently introduced a register called the Competent Persons

Register which brings together individuals and enterprises from all the different building

trades who are registered with a Government approved scheme. To find a Part P

registered electrician, please check the website at www.competentperson.co.uk

The safety bit!

If you do decide to tackle any electrical work yourself, you will find some clear and simple

guides to various electrical jobs around the house on the Diyfixit website at

http://www.diyfixit.co.uk/electrics/

Always take the following precautions:

Locate cables in your wall. A common DIY error is accidentally drilling, nailing or

screwing things into cables hidden inside your walls. Be especially careful before

drilling above or below sockets and switches. A quality cable detector can help you

to track buried cables before you start work and so help to avoid the risk of an

electric shock.

Shut off the power. If you're doing any work near electrical wiring or power

supplies, where possible, shut off the power in your fuseboard and use battery

powered tools. To confirm that all the power is off before beginning DIY plug an

appliance into sockets and operate the lights.

Use an RCD (residual current device). An RCD can save your life by cutting off the

power in the event of an electrical fault caused by a DIY blunder. Make sure you

have one fitted in your fuseboard (consumer unit), and where necessary use a

plug-in RCD. See our previous Circuit Shorts about RCDs.

Check power tools and watch out for the lead. Before using any power tools, check

the lead and plug are in good condition. If you can see signs of damage, such as

frayed wires, get the equipment repaired before using it. Watch out for the power

lead at all times so you don't accidentally cut through or trip over it.

Isolate the circuit you plan to work on by removing the circuit fuse and putting it in

your pocket. Or switch off and lock the relevant circuit breaker. If you can’t lock it,

tape the switch in the off position, and attach a very clear note to the unit stating

that you are working on the circuit.

Check the circuit is dead with a plug-in socket tester or, in the case of a lighting

circuit, a voltage tester. When you have finished, replace the fuse/circuit breaker

and turn the main power switch on again. Never restore power until the faceplates

and covers of all accessories have been fitted.

Spend a little extra and invest in good qualify tools! For instance, good wire strippers will

prevent you from nicking or skinning the wires, good screwdrivers will prevent slipping out

of screw heads or rounding them out. Good tools not only improve the quality of your

workmanship, but improve your confidence as well.

I hope the above gives you some clarity as to which electrical jobs you might want to

attempt yourself and which ones are best left to the professionals (I don't mean Bodie and

Doyle, they're not Part P registered).

Regulations or to make an appointment for a free quotation on any of the services we

Stay safe people!
