What is a consumer unit?

A consumer unit, otherwise referred to as a fuse board acts as the control centre for a properties electrical system. Different consumer units can be used for different applications depending on the property type and size. A consumer unit usually acts as a first point of contact for querying electrical faults within a home, and its interface reflects this. With most consumer units you will expect to see a mains switch, RCD and switches for circuit breakers corresponding to different parts of the property.

What are the different types of consumer unit?

Consumer units can differ depending on the type of property. Units present in commercial properties must consider different use scenarios in addition to safety. Residential/domestic properties require a different set of requirements to detect and remedy faults.

What are the signs of a faulty consumer unit?

While most faults cannot be diagnosed easily, there are a few important things we can look out for with our consumer units to ensure their safety:

  • The physical condition of the unit is important, if you see any cracking, hear any arcing sounds, or can smell burning you should call a certified electrician to inspect the fuse box immediately.
  • If the power in your home is tripping repeatedly, this can often be a sign that an inspection is warranted
  • Periodic inspections of electrical installations should be carried out every 10 years, or every 5 years if a rental property. If your unit has not been inspected for a long period of time, for peace of mind it is best to enquire about an EICR with us.

Why would my fuse box need servicing?

A faulty consumer unit can be a fire hazard, unnecessarily inflate electric bills and interfere with the safe operation of appliances in your home or business.

Can I replace a consumer unit without an electrician?

Consulting a registered electrician is required, work must be completed to the latest safety standards and the task itself requires an understanding of the complex electrical system in your property.

How can I choose the correct consumer unit for my property?

It can be overwhelming to select the correct fuse box for your property with so many options on the market. If you are uncertain and need a helping hand, we have a wealth of experience selecting and installing consumer units in London.

I recently had a hanging pendent ligts over the dining area. Spoke with David over the phone and he suggested us to go with wireless switch for our hanging pendent light. This surely saved us from opening up the walls for sorting out wires. On the day, Marlow came over to install the light and I'm very happy with the work he did. Very friendly and genuine guy. Would definetly come back for future electrical works if needed.

David and Marlowe are the best electricians I’ve ever had. Here’s why:They simply care: They replied to my emergency message immediately, even though it was late at night.Extremely professional: I was slightly panicked when my old electric shower stopped working, fearing major issues like cable damage under the flooring. Here's what they did to solve the problem: 1. They diagnosed the issue, causing minimal damage to my bathroom furnishings. 2. Even though the root cause turned out to be the worst case—cable damage under the floor—they managed to fix it smartly by rewiring from the other side of the wall. This saved me tons of money by avoiding hiring a builder to redo the flooring, and fixed the problem without needing to worry about the old underfloor cable forever!Highly efficient: The diagnosis and fix both happened within 2 hours.Respectful: They cleaned up the mess left by the work as much as possible.Fair and transparent pricing: David makes sure I know the price before the work is carried out. Very fair price comparatively. No hidden fees, no unwanted surprises.

Called David with an emergency as none of the electricity in my flat was working (no fridge/freezer, no WiFi). He immediately responded and was very patient with me and my spotty reception, managing to find the issue really quickly and restore the electricity, following up with advice for how to continue. Really professional, and seriously helpful.
