Answer 5 quick questions
We reply within 24 hours — usually the same hour.
What does your current fuse box look like?
Six signs you need a new fuse board
If any of these apply, your fuse box is no longer compliant with the current 18th Edition wiring regulations — and in most cases, no longer safe.
-
Rewireable fuses
If your board uses fuse wire instead of switches, it's typically 30+ years old and needs replacing.
-
No RCD protection
Modern boards trip in milliseconds to prevent electric shock — old boards don't.
-
Plastic enclosure
Pre-2016 plastic consumer units can catch fire. Metal is now mandatory in domestic settings.
-
Frequent tripping or burning smell
Tells you a circuit is overloaded or a connection is failing — get it surveyed urgently.
-
Failed an EICR
Failed an Electrical Installation Condition Report? A board upgrade is usually part of the remedial work.
-
Adding load — EV, extension, kitchen
Older boards rarely have spare ways or the capacity for modern circuits. Easier to upgrade now.

Frequently asked

How long does a fuse board replacement take?+
Most domestic fuse board (consumer unit) swaps are completed in one day — typically 4 to 6 hours. We isolate the supply, fit the new 18th Edition compliant board, test every circuit and hand you a signed Electrical Installation Certificate before we leave.
Do I really need a new fuse board?+
If yours has rewireable fuses, no RCD protection, plastic enclosure (pre-2016), scorch marks or trips frequently, it's almost certainly time. Modern 18th Edition consumer units add RCBO protection on every circuit and a metal enclosure — far safer and required for compliance on most rented properties.
Will my power be off all day?+
We isolate your supply only while the new board is wired in — usually 2 to 3 hours. We let you know in advance so you can plan around fridges, freezers and home working. Power is fully restored and tested before we leave.
Do you provide a certificate?+
Yes — every fuse board replacement comes with a signed BS 7671 Electrical Installation Certificate, plus building control notification where required. Landlords get a copy formatted for your EICR records.
Do you cover my postcode?+
We cover Croydon, Bromley, Sevenoaks, Tunbridge Wells, Tonbridge, Edenbridge, Oxted and surrounding towns from our Edenbridge HQ and Croydon office. If you're within an hour of either, we install. Not sure? Call 0203 576 6961.
What does a fuse board replacement cost?+
Fixed prices depend on the number of circuits, condition of the existing wiring and the make of board chosen. Most domestic swaps fall between £450 and £850 fully fitted. Send your details and we'll email a fixed, no-obligation quote within 24 hours.
