Electrical rewiring by Plymouth Electricians
When should an electrician carry out a rewire?
Electrical installations, over time, will deteriorate naturally as
they are a working mechanism made up of various components
and working systems.
For wiring systems more than 25 years old we would always
recommend having the electrical system checked out at
This will help identify any faults or defects which could require
improvement. It will also give you an idea of any work that might
be required and potential cost if you are considering upgrading the
electrical installation or remodelling it to include additional circuits.
A full rewire usually takes place when major building work such
as an extension or conversion is being carried out – prior to any
plastering or decoration.
Other occasions when a rewire might be necessary include;
- After ﬂood or fire damage
- If electrical installation has become unsafe
- Installation of several new circuits
- Upgrade of building/property
AT REGULAR INTERVALS.
Some people may want to undertake a full rewire or upgrade the current system – particularly those moving into a new property which
might be 25 years or older. Undertaking a full or partial rewire in a property is a big job and one that should only be carried out by a
registered electrician. Goodwin Electrical in Plymouth have the experience and qualified electricians to design and install a rewire
or partial rewire in your home, office or business premises.
What does the work involve?
Carrying out a rewire will require a large amount of disruption to
the main fabric of a property. It is likely that all switches, fittings,
sockets and the consumer unit will be replaced and require
A total rewire will involve two stages of working; first fix and
All first fix work will take place before plastering work and, usually,
at the same time as any central heating and plumbing work.
This is to ensure all cabling is hidden so the installation will
involve lifting the ﬂoor coverings and ﬂoorboards and possibly the
skirting boards too, chasing out channels in the walls and possibly
in some ceilings that are inaccessible from above.
As well as installing new cabling, first fix stage may involve
fitting new back boxes for all sockets and switches. In addition to
rewiring for all power and lighting circuits, it is a good opportunity
to rewire for modern central heating controls, alarms, smoke
detectors and doorbells, to add outdoor lighting and sockets, and
to rewire the telephones and television aerial sockets. It is also
worth redesigning the wiring plan for sockets and switches to
make sure it meets your needs and those of modern house buyers.
Think about specifying two-way or even three-way switching
for hallways and landings and other rooms with more than one
main access. For a high-value property, consider adding a separate
circuit with separate switching for table and standard lamps in the
main living rooms and principal bedrooms. It may also be worth
considering adding automated lighting, home network cablings,
speaker cabling and other modern technology.
Once the first fix stage has been completed, the property can be
re-plastered or the walls and ceilings filled and made good, and
the ﬂooring replaced. The second fix work can then proceed fitting
sockets and switch plates, light fittings, the consumer unit and
wiring any electric fans, cookers, extractor hoods, electric showers
and the immersion heater, if there is a hot water storage cylinder.
A full rewire can be avoided, providing the existing cabling is
sound and able to carry any additional loads. It also may be
possible to upgrade it by adding a modern consumer unit and
upgrading the earthing and bonding.
What will a new rewire mean?
Having a full rewire will bring the electrical installation in your
property up-to-date with the latest wiring regulations. It will also
give you the opportunity to modernise your home with a new
consumer unit containing residual current devices (RCDs) and
circuit breakers, additional sockets to suit your needs (including
USB sockets should you so wish) and the most up-to-date,
modern wiring available.
It can also be costly and we recommend that you get at least
three quotes before arranging for an electrician to carry out a full
rewire – as the prices quoted could be markedly different.
However, please be aware that the lowest cost does not always
mean the best job – so do your research carefully and maybe look
at examples of other rewires carried out by the firm you choose
to go with.
Notification to Building control
Carrying out a partial or full rewire will often involve creating
new circuits or a consumer unit change. This means the work is
notifiable to your local building control department.
Using a registered contractor with NICEIC or ELECSA means the
person carrying out the work is eligible to do this for you – without
the need for you to do anything. Be sure to arrange this with your
electrician beforehand and get the appropriate certification for the
My property is quite old and I want to know if it needs a rewire?
Before ordering a full rewire it might be worth having a full
inspection of the electrics beforehand. You should contact your
local NICEIC or ELECSA registered contractor and ask them to
carry out an electrical inspection (sometimes known as a periodic
inspection) of the property. Much like an MOT, this is an inspection
of the current condition of an electrical installation in your home.
On completion of the inspection, you will receive an Electrical
Installation Condition Report (EICR) detailing any damage,
deterioration, defects, dangerous conditions and anything not in
line with the present-day safety standard which might give rise
I am considering a full rewire. What building regulations do I need to be aware of?
A full rewire has to be notified to the local building control
department so that it meets the appropriate safety standards.
Speak to the electrician before any work to upgrade your wiring
commences. Find out if the work complies with Part P of the
building regulations and that the appropriate notification and
certification will be taken care of once the work is completed.
A straightforward way of meeting the requirements is to use an
NICEIC or ELECSA registered contractor. They can self-certify
the work and notify the local building control department on
How long will a full rewire take?
A full rewire can take, on average up to between 5-10 days,
depending on the size of the property. The time taken depends
on the number of contractors working and the exact scope of
Why use an NICEC or ELECSA
Choosing an NICEIC or ELECSA registered contractor is a
householder’s best way to ensure a safe job. Electricians registered
with NICEIC and ELECSA are assessed on a regular basis to ensure
high standards and their work is checked against the IET Wiring
Regulations as well as other standards.
