Inspire Electrical has been assessed by ELECSA on behalf of the Isle of Man Goverment and is Part P Approved for domestic electrical work.
This is a document which will detail the results of the inspection and testing a competent electrician will have carried out when doing electrical work in your property. It should be signed by the electrician to confirm that the work complies with the latest wiring regulations. If the work is notifiable under Part P of the building regulations, a copy will also be sent to your local building control department.
The "earth conductor" and "main equipotential bonding conductors" are fundamental for the safety of your electrical installation. Earthing is required so that any fuses, circuit breakers or residual current devices will operate to remove the danger quickly in the event of a fault.
Main equipotential bonding conductors connect any incoming metal items e.g. gas or water mains to the main electrical earth connection. This ensures that no dangerous voltages appear between separate conductive metal parts during a fault.
Any alterations or additions must full comply with the current edition of the wiring regulations, BS7671. In some situations this will mean an upgrade to bonding and/or earthing is required. The Electrical Safety Council have produced some plain english guidance for householders explaining earthing and bonding.
Inspire Electrical will check your earthing and bonding before undertaking any work and advise if an upgrade is required.
A Residual Current Device (RCD) will disconnect the electricity to a circuit if there is a particular type of fault (leakage to earth), such as when a "live" cable is touched by accident. It will not prevent an electric shock, but will limit the duration to a very short time, typically less than 0.04 seconds. This will significantly decrease the risk of death or injury. The wiring regulations, BS7671, now require that RCDs are fitted on all domestic circuits, with a few exceptions, to provide additional protection against electric shock.
A Miniature Circuit Breaker is the first line of defence against electrical faults. In the event of a fault in a correctly designed and installed system, the electricity supply will be disconnected in a very short time, typically less than 0.4 seconds. This helps to reduce the risk of fire and electric shocks.
It can be reset after the fault has been cleared, usually by moving the lever fully into the "OFF" position, then back to "ON". MCBs are a much more convenient replacement for old style BS3036 fuse carriers and fuse wire. Note that a due to their fast operating time, a blown light bulb can occasionally cause the MCB to trip.
The only way to know for sure is to have a competent electrician inspect it. Some of the most common reasons for needing an upgrade include:-
- Existing unit is damaged or has missing parts.
- Insufficient spare ways for any new circuits required.
- No provision for RCD protection of new or existing circuits.
- Fire or heat damage.
- Mortgage lender may have requested an upgrade.
- For user convenience - no more fiddly fuse wire.

It is almost impossible to give timescales and pricing without seeing the particulars of the specific job. Many different factors affect the duration and the cost, such as type of wiring, location and accessibility of existing wiring, type of accessories required, and structure of the building.
All these factors are taken into consideration in your written, no obligation quotation or estimate. Example costs can be found here
