Honest breakdown of fuse board replacement costs in Winchester, what affects the price, and what you get for your money.

Fuse Board Upgrade Costs in Winchester (2026)

The cost of a fuse board upgrade in Winchester typically ranges from £800 to £1,500 depending on the size of your property, the number of circuits, and the type of consumer unit fitted. A standard 3-bedroom home usually costs around £800-£1,000 for a dual RCD board, while larger properties or those requiring RCBO protection may cost £1,200-£1,500.

What Affects the Price?

• Number of circuits — More circuits mean a larger consumer unit and more work
• Type of board — Dual RCD boards are cheaper than full RCBO boards
• Condition of existing wiring — If remedial work is needed, this adds to the cost
• Location of the board — Moving the consumer unit to a new location costs more

All Orsidaen fuse board upgrades include the consumer unit, installation, full testing, an Electrical Installation Certificate, and building control notification.
