Why should you replace your fuse board?

Fire safety – In the UK, one of the main factors contributing to house fires is electrical failures. Fire investigators’ reports reveal a recent trend of a rise in the occurrence of fires involving consumer units (fuse boards). Numerous fires were caused by poor cable connections, which caused consumer units to overheat. The switch from plastic consumer unit cabinets to non-combustible materials, including steel, was made as part of the 17th Edition Wiring Regulations Amendment 3 and went into effect in January 2016. This will significantly lower the chance of a fire spreading.

Protection against lethal electric shocks from touching live objects, such as bare wires, is provided by an RCD, or residual current device, which is a life-saving feature on all current 18th Edition consumer units. Additionally, It might also provide some safety from electrical fires. With conventional fuses and circuit breakers, there is no way to provide the level of personal safety that RCDs do.

If your current fuse board is full, and you need an extra circuit, maybe for an electric oven, shower or EV charging point, altering your fuse board can offer additional approaches. In contrast to modern domestic dwellings, which are employing more and more electrical appliances than 20 years ago, older fuse boards contain fewer ways (4–8) than modern consumer units (10–24 ways). This is because fewer circuits were necessary in the past.

Difference between consumer unit & A fuse box

It can be unclear what the terms “consumer unit” and “fuse box” actually mean, we explain them below:

  • Fuse box: Historically, the most popular electrical safety device was the fuse box. When a difficulty with the electrical circuit arises, they contain fuses that melt and cut the power. Although it may seem trivial, it can sometimes take a few seconds for the fuse to melt and interrupt the electrical circuit. This increases the risk of fires and electrical damage significantly.

  • Consumer unit: Consumer units are more modern and safe; they shut off the electricity if the power in the house rises too much. The distinction is that consumer units are significantly safer because they can promptly cut off the power when they detect electrical faults. Unlike fuses, the circuit breakers only need to be switched back on after the electricity is turned off.

Consumer Unit Types

There are many distinctive types of consumer units, and each one operates differently. These comprise of:

  • Split load consumer unit
  • Fully loaded consumer unit
  • EV charger consumer unit
  • Garage consumer unit
  • Shower consumer unit
  • RCD dual split consumer unit
  • Domestic switch fuse
  • High integrity consumer unit

 

What will I get?

When you have a fuse board replacement your new consumer unit will comply with IET Wiring Regulations and be equipped with Residual Circuit Devices (RCDs) and miniature circuit breakers (MCBs) (BS7671:2008).

Split load fuse boards must be equipped with two RCDs per the current regulations. This means that even if one RCD trips, you will still have lighting and power. All new consumer units must be made of metal starting in 2016. The most recent regulations will no longer be met by plastic ones.

After installation, we will label the consumer unit and issue a certificate attesting to the electrical installation’s quality and compliance with Part “P” of the building regulations.

Components of a Consumer Unit

There are three main components that make up a consumer unit:

  • The main switch. This is the main isolation control for your entire home. You can immediately turn off the electricity by flipping the manual main switch if you need to in an emergency.
  • Circuit breakers. Each circuit breaker is designated for a certain part of your home’s electrical system, such as the lighting upstairs. The circuit breaker shuts off the electricity to stop electrical fires when the circuit is overloaded (too many electrical devices are connected) or if the current reach excessively high levels.
  • Residual Current Devices (RCDs). Similar to circuit breakers, each RCD normally protects half of your home and will turn off the electricity if the current grows too high.

Will any damage be caused to my property?

There is no reason for a qualified electrician to damage walls or ceilings if the fuse board is close to the electric metre. Since consumer units are typically larger than earlier fuse boards, any existing cable entrance or fixing holes will generally be covered.

What will it cost?

Upgrades to fuse boards should cost between £300 and £500, depending on your needs and the electrical system in your home. We will do a site survey and offer a fixed price for the work that will include:

  • All materials. This includes a premium METAL fuse box with breakers (to current regulation)
  • All labour. One of our certified domestic installers will perform the installation
  • Installation Certificate. A certificate will be registered with your local council or building rules
  • 24-Month Guarantee. A warranty covering all parts and labour

Factors that will affect the cost

It is crucial to take the following things into account when determining the cost of a fuse board replacement:

  • Home size. Larger properties contain more electrical appliances, thus they will need a large consumer unit with a higher capacity, which will cost more money.
  • The consumer unit type. There are many distinctive types of consumer units, each with different pricing, as we explained in the previous section.
  • Condition of the existing fuse board. You may be charged a cost to remove the old unit when replacing a fuse box or consumer unit. If the old unit is in bad shape, this fee can go up.
  • Electrical inspection. It will cost between £120 and £300 to do an electrical inspection to determine the safety of your current wiring.
  • Adding additional circuits. When installing a new consumer unit, you may also want to add new circuits for additional sockets, lighting, an EV charger, or wiring, all of which will be more expensive. Our domestic electrical hourly rate is £75 per hour.

 

Will any additional work be required?

Once the consumer unit is installed, a certified electrician will test all of the currently installed circuits. Before issuing an Installation Certificate, any electrical installation faults that already exist will need to be fixed, which could incur additional costs.
