Part P came in to force in January 2005. Here are the highlights.
All electrical work carried out in a kitchen, bathroom or shower room requires notification
to the local authority building control.
All electrical work outside in a garden, shed, garage or remote building requires
Installation of under floor or overhead heating requires notification.
Any new circuit (not an extension of an existing one) in any room in the house requires
Extensions to existing circuits which are not in the places mentioned above are not
notifiable unless the area is communal.
A recent application I made to Maidstone council for notifiable works of £2000 was
going to cost over £360 to notify. (June 08)
The office of the Deputy Prime Minister, John Prescott at the time, introduced Part
P into the building regulations in January 2005.
They apply to all domestic dwellings, even flats above shops. The idea was to cut
the amount of deaths caused by electrocution caused by incorrectly installed electrical
circuits. Plainly put to stop cowboys and DIYers.
Certain works are now notifiable to building control, as you can see from the third
column here. You can do this by making an application to the local planning office
but this is extremely expensive, the alternative is to use a tradesman who is a member
of a competent persons scheme such as NAPIT.
Such a tradesmen can self certify their work and carry out the notification using
the scheme they are enrolled in for a nominal cost.
If you are getting quotes for electrical work ensure that the person is a member
of such a scheme to ensure that the work will be notified and completed to the regulations.
You may have problems when you sell your house or invalidate your insurance if you
have work done that is not notified.
The 17th edition wiring regulations came in force in 2008. They are often called
the RCD regs, here is why.
All cables buried less than 50mm deep in a wall to be mechanically protected by armouring,
protected with an earthed metal sheath/conduit OR circuits protected by a 30mA RCD
If lighting circuits are protected by an RCD to comply with the above then they should
be split between more than one for safety.
All domestic socket outlets should be protected by a 30mA RCD
All circuits in a room containing a bath or shower should be protected by an 30mA
All circuits supplying mobile equipment not exceeding 32A for use outdoors (lawnmower,
strimmer, pond pump, lighting) should be protected by a 30mA RCD.
