When do you need a Consumer unit upgrade?
You will need this service if your property has an old-style fuse board with rewireable fuses, if you are experiencing frequent electrical tripping, or if you are planning major electrical work or a property sale.
What happens on the day
A qualified electrician will arrive to safely disconnect your old fuse board. They will install the new consumer unit, perform necessary testing to ensure all circuits are safe, and issue an electrical installation certificate upon completion.
How to prepare

- Unplug sensitive electronics before the work begins.

- Ensure someone is available to grant access and answer any questions.
How to improve your result
- A modern consumer unit offers enhanced protection, including RCDs (Residual Current Devices) that save lives.
- Consider a consumer unit with surge protection to protect valuable electronics from power surges.
- Combine this upgrade with an EICR (Electrical Installation Condition Report) to get a full overview of your electrical system's health.
Why it is useful day to day
A modern consumer unit provides peace of mind, knowing your home's electrical system is safe, reliable, and capable of handling today's electrical demands without frequent trips or hazards.
Why we ask these questions
We ask about the age and type of your current fuse board, the number of circuits, and any plans for future electrical upgrades (e.g., electric car charging, new kitchen). This helps the electrician specify the correct size and type of consumer unit needed for your property's demands.
