Consumer Unit Replacement in Shropshire
Modern RCD and RCBO consumer units installed across Telford, Shrewsbury and Shropshire. Same-day Electrical Installation Certificates from NICEIC and NAPIT registered electricians.
What is a consumer unit replacement?
Your consumer unit — still called a fuse board by a lot of people — is the single most important safety device in your property. If it's old, damaged, or missing modern protection, it's one of the most common findings on an EICR. We replace consumer units across Telford, Shrewsbury and Shropshire, upgrading homes and small businesses to modern, compliant boards with full certification on the day.
Signs you need a new consumer unit
- Your board still has a wooden back, cast-iron switches, or ceramic fuses instead of circuit breakers
- Your EICR flagged the consumer unit as a C2 or C3 observation
- You're extending, rewiring, or adding a garage/outbuilding supply
- You've had breakers tripping repeatedly or a board that feels warm to the touch
- You're installing an EV charger and the current board can't safely support it
- You're selling or renting the property and want to clear a known defect before it becomes a buyer's or landlord's problem
What's actually changing
A modern consumer unit gives you RCD (Residual Current Device) and, on most circuits, RCBO protection — devices that cut power in a fraction of a second if they detect a fault, protecting against both electric shock and electrical fire. Older ceramic fuse boards and early plastic consumer units without RCD protection simply can't do this. It's the difference between a circuit tripping safely the moment something goes wrong, and a fault being left live.
What's involved
1. Survey
We confirm the number of circuits, board size, and any existing issues before quoting.
2. Isolation and removal
The supply is isolated and the old board is safely removed.
3. New metal-clad unit
A new metal-clad consumer unit is installed. Metal casing is a fire safety requirement under current regulations.
4. Testing and EIC
Circuit-by-circuit testing of the full installation, then issue of an Electrical Installation Certificate (EIC) — the formal certification required by law for this work.
Typical timeframes
Most straightforward domestic replacements are completed in a single day, with the power off only for the duration of the swap.
Typical pricing (guide only)
- Standard domestic consumer unit (up to 10 ways): typically £550 – £900
- Larger domestic board (10+ ways): typically £800 – £1,250
- Small commercial board (single-phase): from £550
- Small three-phase board (e.g. 4-way): from £700
- Larger three-phase distribution board: typically £1,200 – £2,000+
- Consumer unit + minor remedial work from an EICR: quoted after survey
Final price depends on the number of circuits, board accessibility, and whether any additional remedial work is needed alongside the swap. We'll always confirm this with a written quote before booking.
Consumer Unit FAQs
Yes — “fuse board” and “fuse box” are the older, more familiar names for what's now called a consumer unit. Modern units use circuit breakers and RCDs rather than fuse wire, but people still use the old name day to day.
Not automatically — but if an EICR codes it as C1 or C2, it needs addressing before the report can be marked satisfactory, and most landlords, insurers, and mortgage lenders will expect this to be resolved.
Yes, briefly — the supply needs to be isolated for the swap itself, typically for a few hours during the day. We'll agree timing with you in advance so you can plan around it.
Yes, and it often should be — if you're replacing the consumer unit anyway, it's the ideal time to have the rest of the installation tested so any other issues are caught in the same visit.
Yes. All consumer unit replacements are notifiable electrical work and you'll receive an Electrical Installation Certificate (EIC) confirming the work meets BS 7671.
