Fuse Board Replacement

Old fuse boards can leave owners uneasy, especially when lights trip unexpectedly or sockets feel warm. If you are searching for fuse board replacement in London, you want clear advice, safe installation and a contractor you can trust in your home, business or rental property. First Action supplies planned and urgent fuse box upgrade work across Greater London, replacing outdated equipment with modern consumer units that improve electrical safety and meet current regulations.

When should I replace my fuse board

A fuse board should not be left in place indefinitely. Clear warning signs include wooden backed enclosures, cast iron or ceramic switches and a collection of mismatched fuses that have clearly been added over decades. If your board looks more than forty years old, or has been altered many times, an electrical inspection by a NICEIC electrician is strongly recommended.

Even if the electrics still function, older equipment rarely offers the same fault protection as a modern 18th edition consumer unit. Upgrading is particularly important when you renovate a kitchen, add a loft conversion, install an electric shower or increase the number of sockets and appliances in daily use.

What is included in a modern consumer unit

A modern consumer unit upgrade replaces the old fuse board with a metal clad enclosure that contains miniature circuit breakers and devices that constantly monitor the flow of electricity. Central to this is RCD protection or residual current devices. These life saving components trip rapidly if someone touches a live part or if a fault develops that could cause a fire.

First Action supplies and installs:

  • Domestic consumer unit replacements

  • Garage and outbuilding consumer units

  • Shower and bathroom units

  • MCBs, RCBOs, RCDs and RCCBs

  • Appropriate accessories and labelling

All work is tested and certified on completion so you have written confirmation that circuits meet current British Standards.

Why fuse board replacement matters for landlords

For landlords, landlord electrical safety is not only about good practice, it is a legal duty. The Landlord and Tenant Act 1985 and the Electrical Equipment Safety Regulations require that electrical installations are safe at the start of every tenancy and maintained in a safe condition. Failure to address obvious deficiencies in an old fuse board may expose landlords to enforcement action, invalid insurance and serious risk to tenants.

By commissioning London electricians who understand both the law and the technical standards, you protect people and demonstrate that reasonable steps have been taken to comply. An upgraded consumer unit also supports EICR reporting and can reduce the number of coded defects on future inspections.

How much does fuse board replacement cost

At First Action, typical fuse board replacement packages start from around £300, with final pricing depending on the number of circuits, the condition of existing wiring and any extra work required to bring bonding or earthing up to standard. Before work begins, an engineer will inspect the installation, explain any issues in plain language and provide a clear written quotation.

If your fuse board looks like any of these we strongly recommend a fuse board replacement.

Landlords are obligate to comply with statutory regulations and safety or face significant risks and fines.

The Landlord & Tenant Act 1985, statutory regulations, requires that electrical equipment is safe at the start of every tenancy and maintained in a safe condition throughout the tenancy.

Failure to comply with the Electrical Equipment (Safety) Regulations 1994 is a criminal offence.
