How much does a new consumer unit cost – Advice from Electriman, North London Electricians

## How Much Does a New Consumer Unit Cost in the UK?

Replacing your consumer unit (also called a fuse box) is one of the most important electrical upgrades you can make. Here's what you need to know about the costs involved.

### Typical Costs

- **Supply only (unit cost):** £50–£200 depending on size and type

- **Labour only:** £200–£500 depending on location and complexity

- **Full installation (supply + labour):** £300–£800 for most homes

- **Large homes or complex rewires:** £800–£1,500+

### What Affects the Price?

- **Number of circuits:** A 10-way board costs more than a 6-way

- **Type of protection:** RCBO-protected boards (one device per circuit) cost more but offer better protection than dual RCD boards

- **Metal vs plastic:** Since 2016, metal-clad units are required by BS 7671 — older plastic units cannot be legally installed as replacements

- **Location:** London and the South East typically cost 20–30% more than other regions

- **Access and additional work:** If cables need extending, earthing needs upgrading, or the meter tails require replacement, costs rise

### Types of Consumer Unit

- **Dual RCD (split load) board:** Lower cost option, typically £300–£450 fitted — less protection if one RCD trips

- **Full RCBO board:** Each circuit has individual protection, typically £450–£700 fitted — preferred option

- **Smart/Surge Protected boards:** £600–£1,000+ fitted

### What Should Be Included?

**Always ask you
