Consumer Unit Changes

The electrical wiring regulations BS7671 have recently changed so that every new consumer unit fitted has to be made from fire resistant material to improve safety. The new 18th edition consumer units (fuse boards) are easy to use and are much safer in protecting your family in the unlikely event of a fault occurring. We are experts in consumer unit changes.

In the UK many homes are still equipped with an old style fuse box, often with rewirable fuses and without something called RCD protection.

Residual Current Devices (RCD‘s) are switches that trip a circuit under dangerous conditions, and instantly disconnect the electricity.

At AGW Electrical Services, we would always highly recommend that you upgrade your existing fuse board by asking us to undertake a consumer unit change to the latest RCD or RCBO protected fuse board.

This will ensure the safety of your family in the event of a fault, and also ensures that you comply with the very latest electrical wiring regulations.

Make your home a safer place, change your fuse box

Some call them a fuse box, others a fuseboard, the correct name is a consumer unit. Everyone understands that replacing the old one will make your electrical installation much safer. Your right, infact 1000 x safer to be precise. They protect you with an advanced technology known as RCD protection. Yes they have replaced the necessity to rewire an old fuse carrier with fuse wire. Should they overload you just reset those trip switches. However things have got far more advanced than this.

Imagine replacing an old boiler with a boiler that cuts out when it detects water leaks. Once the new boiler is replaced, it's going to find those leaks and cut out. The same can be said for your new consumer unit. Those Rcd's are going to find the leaks you never knew you had, after all not even an electrician can see electrical leaks. Your new consumer unit is going to trip out whenever it detects a leak.

We do things a better way

We take a different approach to changing your consumer unit.
STEP 1: We carry out some pre checks and tests, get to know your system and find any leaks or other surprises in advance. We can let you know, if their are going to be any further costs before, rather than finding out afterwards.

STEP 2: Once we're happy and your happy and any problems found have a solution we will proceed with the change over.

Consumer Unit Replacements | Fuse Box Replacements

A fuse box is a particularly old fashioned term for what we now call your consumer unit. The consumer unit is an integral part of your properties electrical system and is responsible for powering all the circuits in your home.

It is made up of various parts and is made up from various parts, such as: mains switch, residual current devices (RCD’s), RCBO’s and miniature circuit breakers.

You should always know where your consumer unit is located in case of emergency and you need to turn it off or on.

If you have an older style fuse box, perhaps with fuses that you need to insert wire into (rewirable fuses) to make it work, this doesn’t mean that it is unsafe.

In fact, we have changed consumer units for many customers that live in houses where it has been this way for 30, 40 or even 50 years.

Having said that, the older style fuse boards were designed to manage an older, far more basic design of wiring system. Not like a modern wiring installation, designed to cope with the ever changing demands of modern day homes. Changing your fuse board, for a new consumer unit, does not mean that the wiring design or the capacity it can handle will change. You are simply upgrading your electrical installation to be far safer.

With the increased use of more and more appliances such as microwaves, TV’s, Hot Tubs and such, there is an increased likelihood that traditional style consumer units and the limits with your existing wiring ‘could’ suffer an overload. 

Without modern safety devices, like RCD protection for example, this can lead to a fire, electric shock or even death..

How Can We Help?

When you decide to replace an old fuse board, for a new RCD consumer unit. It sometimes isn’t as straight forward as this relatively simple task would seem for a qualified electrician. Before we replace your fuse board it is necessary to ensure your wiring has no faults and that the current wiring is earthed correctly to ensure the consumer unit will work as it should. You may have had small faults within your wiring for a long time. The old rewirable fuses are not sensitive enough to pick up on these faults. But once replaced the new consumer unit, this would find the slightest fault that may have always been there. 

We are equipped with the most advanced testing equipment available. This equipment can find these faults and problems quickly. Combine this with our wealth of experience and continually keeping up to date with the latest advancements in technology. Continually furthering our education with up to date, current regulations and testing qualifications. You are in the best possible hands.

Which fuse box?


Things go much further than just trip switches and brands when you are thinking about which fusebox to install.


The latest 18th edition electrical regulations encourages that an 18th edition fuse box ( or consumer unit and they are correctly called) should be installed. The latest 18th edition consumer units include a surge protection device to protect the wiring and appliances from lightning strike and glitches in over voltages within the electricity supply to your home. It is essentially designed to prevent damage to tv s laptops and other sensitive equipment over a prolonged period of time. And acts as a cushion to absorb any spikes in voltage that your expensive appliances would otherwise be exposed to.


An 18th edition consumer unit also includes RCBO protection which moves away from the 17th edition consumer units dual rcd set up. RCBO s detect the slightest fault within each individual circuit. RCD s on the other hand detect faults in multiple circuits and should they detect a fault cut power to them all.


RCBO s are far more customisable in the way they can be selected for more refined purposes such as car chargers and other Direct Current applications that are approaching all our lives quicker than we appreciate.


However it is also still allowed for 17th edition consumer units to be installed, which makes a noticeable difference in the cost of a house rewire or consumer unit replacement. Be vey wary of this when comparing quotes. A house rewire is not a standard procedure with standard equipment. Make sure your quotes are all comparable on a level playing field. When companies feel they are compared on cost, you can expect a lower quality product (and installation)


As long as conditions are suitable we will install either consumer unit for you to meet your requirements and of course everyone has a budget. But we do want to be honest and help you understand the difference. Not only with your choice of consumer unit, but throughout all other aspects of your house rewire. So you can understand the differences, and choose the right equipment, design and contractor to rewire your home.
