Consumer Unit Upgrades in Braintree CM7

Braintree Electrical Services covers consumer unit upgrades in Braintree, Witham, Halstead, Coggeshall, Kelvedon and the wider Essex area. This page explains what an upgrade involves, the signs that it is time to act, and how to send an enquiry.

The consumer unit is the box where the mains supply enters your electrical installation and is split into separate circuits, such as lighting, sockets and a cooker. It also holds the protective devices that cut the power if something goes wrong. An upgrade means replacing the old unit with a modern one that meets current wiring regulations.

In practice the electrician isolates the supply, disconnects each circuit, removes the old fuse board and fits the new consumer unit. Each circuit is then reconnected and labelled. A modern unit normally includes protection such as RCDs, which are designed to switch off the current quickly if there is a fault or a person comes into contact with a live part. Older fuse boxes may have little or none of this.

Because the supply has to be off while the work is carried out, expect some disruption. Plan around anything that needs power, such as work computers, medical equipment or a freezer full of food, and mention these when you get in touch.

Many people only think about their fuse box when something goes wrong. It is better to act before that. Common reasons to ask about consumer unit upgrades include:

An old unit with rewirable fuses, or a board made largely of brown or black plastic or with a wooden backing. Fuses or breakers that trip often for no obvious reason. Buzzing, a burning smell, scorch marks or heat around the unit. Warm or damaged switches. A planned extension, new kitchen, electric vehicle charger or other addition that needs more circuits. An EICR report that recommends the unit is improved.

If you notice burning smells, sparks or heat from the unit, switch off at the mains if it is safe to do so and keep clear until a qualified electrician has looked at it. Do not take the cover off to investigate yourself.

Even if nothing seems wrong, an old installation is worth checking, especially if you have just bought a property and do not know when the electrics were last looked at.

An EICR, short for electrical installation condition report, is an inspection and testing of the existing fixed wiring. It records the condition of the installation and lists any observations or items needing attention. If the report finds that the consumer unit is outdated or unsuitable, replacing it is a common recommendation.

The two jobs are separate but often connected. Some people book an EICR first and then upgrade the unit based on the findings. Others have a unit replaced and want to understand the wider condition of the wiring afterwards. Landlords, buyers and sellers, and commercial property owners often come to this page after an inspection has raised the question.

Braintree Electrical Services offers EICR in several forms, so you can mention in your enquiry if you already have a report, or if you would like to find out what condition the installation is in before deciding.

Nobody can responsibly give a fair price for consumer unit upgrades without knowing the property. Several things affect the cost of the main job:

The size of the installation and how many circuits need to be connected. The type of unit chosen and the protective devices it includes. The position of the existing unit and how easy it is to reach. Whether the existing cabling is tidy and suitable to reconnect. Any extra items you want added, such as surge protection or space for future circuits.

It also helps to keep the upgrade separate from any follow-up work. While the old unit is out, or while testing is carried out, the electrician may find problems such as damaged cables, poor earthing or bonding, or circuits that do not behave as they should. Putting these right is remedial work. It is a different job from swapping the unit and is usually priced separately.

Ask any electrician how remedial work would be handled before you agree to go ahead, and check that any quote says clearly what is included. The rules can change, so check GOV.UK for the current position on notifying and certifying this kind of work.

Replacing a consumer unit is not a casual DIY job. It involves the live supply, and the work is expected to meet Building Regulations and the wiring regulations. For that reason it is wise to use a competent electrician and to ask in advance what paperwork you will receive.

After the work you should expect an electrical installation certificate, or similar documentation, describing what was done and the test results. Keep it safe. You may need it for an insurer, a landlord obligation, a mortgage lender or a future sale. If a tradesperson cannot explain what paperwork comes with the job, treat that as a warning sign.
