How much does it cost to replace a consumer unit?

A standard domestic consumer unit replacement starts from £595 + VAT depending on the number of circuits and the condition of the wiring. We give a fixed written price before starting.

How long does it take?

Most domestic consumer unit replacements are completed in a single day. We isolate the power, fit and wire the new unit, test every circuit and issue your certificate.

Do I really need to upgrade my old fuse box?

If your board has rewireable (wire) fuses, no RCD protection, or is showing signs of age or damage, upgrading is strongly recommended for safety — and is often flagged on an EICR.

What’s the difference between an RCD and an RCBO?

An RCD protects against electric shock; an MCB protects against overload. An RCBO combines both in one device per circuit, so a fault on one circuit doesn’t take out the rest of the house. We fit RCBOs as standard where appropriate.

Will the power be off while you work?

Yes — the power is off for the bulk of the job while we replace and test the unit. We’ll let you know timings in advance so you can plan around it.

Do I get a certificate?

Yes. Every replacement is certified with an Electrical Installation Certificate and notified to building control under Part P, backed by our 3-year workmanship guarantee.

A modern consumer unit is one of the most cost-effective safety upgrades you can make. If your board still uses rewireable fuses or has no RCD protection, it’s worth replacing — often the same day. Pair it with an EICR to confirm the rest of your wiring is safe.
