Consumer Unit Replacement in London, Essex, Hertfordshire and Cambridge

New Consumer Unit Installation

Consumer Unit Replacement and Installation

The consumer unit is the most important part of any electrical installation containing very important over-current and protective devices so that in the event of any fault occurring, the power is disconnected from the problem circuit.

With the correct type of unit installed you will have more protection against electrocution and fires in the home and at work.

AC1 have many years experience working in both occupied and unoccupied properties. All work conforms to current BS7671 18th edition regulation standards.

On completion, AC1 will provide a full installation certificate and Part P notification.

Failed an EICR?

Has your property failed an EICR because of the consumer unit? Upgrade your fuse box with AC1 Electrical Services! Your Consumer Unit or Fuse board plays a major role in the prevention of electric shock and fires within an electrical installation.

New RCD to protect you

RCD Stands for residual current device. These are very important devices within your electrical Consumer Unit. They detect the presence of fault current and limit the flow of electricity to 30ma protecting you from potentially fatal electrocution.

MCBs that protect your property

MCBs stand for Miniature Circuit Breaker. These are also a very important device within your Consumer Unit. MCBs stop the overload of current flowing through a circuit, preventing any electrical fires that may occur. They also disconnect when a fault occurs such as a short circuit.

Metallic Consumer unit

It is now a regulation that all Consumer Units installed or replaced must be metal. Before this the majority of Fuse Boards were plastic which is classes as a combustible material. Having a metallic Consumer unit will reduce the risk of an electrical fire within a Consumer Unit if a fault was to occur.

Old Wooden Fuse box

If your property has on old style Consumer unit or Fuse Board that is made of wood then it is highly recommended that you upgrade this to a new style Fuse box. Wood is a highly flammable material making it a lot easier for it to catch fire under fault conditions.

Old Fuse wire

Does your fuse board have the old style fuse wire in it? Fuse wire takes a lot longer to blow than what a new style MCB does to trip. The longer current is allowed to flow when a fault occurs the higher there is a risk of fire. You also have to rewire a fuse when you can simply reset an MCB.

+
What does replacing a consumer unit involve?

It is standard procedure that as a part of replacing your consumer unit your existing electrical wiring must be fully tested. See EICR reports and certificates for more information on electrical testing and inspections.

Our qualified and competent electricians will carry out a series of tests to ensure that your existing wiring is suitable for a modern '18th edition' consumer unit with incorporated RCD (Residual Current Device) before installing it. Without such testing, there is a possibility that the new consumer unit will pick up any existing underlying wiring faults and continuously trip, leaving you without power.

Usually there are no problems when installing a new consumer unit fuse box (people still call it a fuse box but fuses are no longer used). If there are problems, we will highlight these, allowing you to make appropriate decisions on whether to proceed or not, in rare circumstances the electrical wiring within the existing installation may be so outdated or faulty it will require part or full rewiring.

+
Can you replace a consumer unit in an occupied building?

AC1 have many years experience replacing consumer units and distribution boards in occupied and unoccupied properties.

+
Is your consumer unit installation work guaranteed?

All our work and supplied fixtures and equipment are guaranteed for a minimum of 1 year.

+
What is an MCB?

MCB stands for ‘miniature circuit breaker ‘, A circuit breaker is an automatically operated electrical switch designed to protect an electrical circuit from damage caused by over-current/overload or short circuit. Its basic function is to interrupt current flow after Protective relays detect faults condition.

AC1 can install or upgrade consumer units with new MCBs.

+
What is an RCD?

RCD stands for ‘residual current device’ and is designed to prevent you from getting a fatal electric shock if you touch something live, such as a bare wire. It can also provide some protection against electrical fires. RCDs can help protect you from electric shock in potentially dangerous areas like bathrooms and gardens, and there are various types of RCDs that can be used to make sure you are always as safe as possible.

+
What is RCBOS?

RCBOS stands for Residual Current Circuit Breaker. It combines the functionality of an MCB and an RCD

If your consumer unit uses RCBOS, your circuits are protected individually. This might mean some of your lighting stays on when there's a fault on another circuit. Each circuit is protected individually.

RCBOS consumer units cost a bit more than RCD consumer units, but it can save you from losing all power in your property at the same time.

+
Which consumer unit should I get?

A RCBOS consumer unit protects each circuit individually. It's better than an RCD consumer unit, but costs more.

A dual RCD consumer unit allows two groups of circuits to be protected separately. If one circuit has a fault, the other circuit might be unaffected. It's cheaper than a RCBOS consumer unit, but still has some separation between circuits.

If you don't have RCBOS, and just have an RCD consumer unit, you still have fault protection but a fault on one circuit will remove power from multiple circuits.

+

AC1 is fully insured for domestic and commercial electrical work on customer premises.
