Tests are also carried out on wiring and associated fixed electrical
equipment to check that it is safe. A schedule of circuits will also be
provided, which is invaluable for a property.
Why is a periodic inspection needed?
Every electrical installation deteriorates with use and age. It is
important for the person responsible for the maintenance of the
installation to be sure that the safety of users is not put at risk, and
that the installation continues to be in a safe and serviceable
According to Government statistics, each year on average 10 people die
and about 750 are seriously injured in accidents involving unsafe
electrical installations in the home.
When is a periodic inspection needed?
It is recommended that periodic inspection and testing is carried out at
10 years for a domestic installation
5 years for a commercial installation
3 years for caravans
1 year for swimming pools
Other instances when a periodic inspection should be carried out are:
We will check the electrical installation against
the requirements of BSi7671
- Requirements for Electrical Installations ( IEE Wiring Regulations) -
as amended, which is the national safety standard for electrical
installations, and contains around 850 Regulations.
The period inspection will take into account all relevant circumstances
including the following factors:
Adequacy of earthing and bonding
Suitability of the switchgear and
controlgear e.g. consumer unit, distribution boards, light switches
Serviceability of equipment e.g.
switches, socket-outlets and light fittings e.g. older round pin
sockets, round light switches and skirting boards may require
Type of wiring system and its condition
e.g. cables coated in black- rubber, black-rubber was phased out in
the 1960s or cables coated in lead or fabric are even older and may
need replacing (modern cables use pvc insulation)
Provision of residual current devices
for socket-outlets that may be used to plug in electrical equipment
Presence of adequate identification and
Extent of any wear and tear, damage or
Changes in use of the premises which
have led to, or might lead to, deficiencies in the installation.
We will provide a periodic inspection report (PIR) as part of the
What is a periodic inspection report?
A period inspection report (PIR) is a formal method of recording the
findings of the periodic inspection.
The main purpose of a PIR is to report on the safety condition of an
existing installation. It will describe the overall condition as either
'satisfactory', in which case no immediate
remedial work is required, or 'unsatisfactory'
which means remedial work is required to make the installation safe to
It will also include a summary of the inspection in the report, which
will give a clear indication of the condition of the electrical
installation, taking into account all relevant circumstances.
What happens after a periodic Inspection?
That is up to you, however, any recommendations regarding the safety on
the installation should be carried out immediately.
