Fuseboard upgrades in the UK typically fall in a broad band because every property is different. As a rough guide, expect somewhere between £450 and £900 for a straightforward domestic swap.
What affects the price
- Number of circuits — a larger board with more RCBOs costs more in parts.
- Condition of existing earthing and bonding — upgrades may be needed to make the new board compliant.
- Access to the meter tails and whether the DNO needs to disconnect.
- Any remedial work that comes to light during pre-installation testing.
What a good quote should include
Metal-clad consumer unit, RCBO protection per circuit where sensible, full testing, an Electrical Installation Certificate, and Building Control notification. We include all of that as standard.
