MX2 Electrical is frequently praised for prompt, professional and friendly service, with electricians who explain the work clearly, offer options and complete jobs efficiently. Reviews commonly mention EICRs, EV charger installations, sockets, lighting, wiring, ventilation, consumer units and cooker work, with neat finishes, tidy work areas and fair pricing standing out. A small number of reviews raise concerns about follow-up costs and remedial work after EICRs.

Summarised with AI

I’m Really happy with the work from both of them. They installed a new socket in our conservatory and did a great job. They were both professional, friendly, tidy and made sure everything was done properly. I’m very pleased with the result and would definitely recommend them. Thank you both for your hard work!

MX2 came along promptly to quote, their quote was reasonable and they gave us options. The work itself was done quickly, efficiently and very neatly, they went the extra mile adding extra without quibbling, and they left the flat in a very tidy space.

Check whether replacement is right

Modern electrical demands and safety regulations make upgrading an obsolete fuse board an important safety improvement for domestic properties.

Rewireable fuses and wooden boards

Older properties in Wimborne Minster, Wareham and Westbourne often still contain wooden-backed fuse boards with rewireable carriers. These offer no residual current protection against electric shocks or electrical fires.

Missing RCD protection

Twentieth-century homes in Broadstone, Canford Heath and Ferndown may have early cartridge fuse boxes or basic miniature circuit breakers without RCD switches. Modern standards require RCD protection across socket and lighting circuits.

Renovations and added circuits

Adding new circuits for kitchen extensions, heat pumps or electric vehicle chargers in Bournemouth and Poole requires spare capacity and modern protective devices that older consumer units cannot support.

What the replacement covers

Our standard replacement service covers the physical unit swap, testing and statutory certification.

Included when agreed

  • Isolation of the electrical supply and removal of the old fuse board
  • Installation of a metal consumer unit compliant with current wiring regulations
  • Fitting of individual circuit protection devices including RCDs and circuit breakers
  • Inspection and testing of all connected final circuits
  • Issue of a Building Regulations compliance certificate via NAPIT
  • Supply of an Electrical Installation Certificate recording all test values

Not included automatically

  • Rectification of pre-existing faults on existing household wiring
  • Upgrading supplier equipment, meter tails or main service cut-out fuses
  • Plastering, painting or decorating work around the new board location

How the job works

Replacing a consumer unit requires turning off the power and carrying out structured safety checks across the property.

  1. 01

    Preparation and pre-installation tests

    Clear the area around the existing fuse board and meter. We perform initial continuity and insulation resistance tests on connected circuits before isolating power to identify pre-existing faults.

  2. 02

    Board installation

    Power to the property will be turned off while the old unit is disconnected and removed. We mount the new metal enclosure, connect the incoming supply tails and terminate each circuit into its dedicated breaker.

  3. 03

    Testing and energisation

    Once wired, power is restored step by step. We carry out full instrumental testing on every circuit, checking trip times, earthing loop impedance and polarity to confirm safe operation.

What you receive

Following the installation, you receive full documentation certifying that your new consumer unit complies with electrical safety regulations.

Replacement board
A fully labelled metal consumer unit fitted with modern protective devices suited to your installation, such as residual current devices and miniature circuit breakers.
Circuit test results
A complete schedule of test results documenting insulation resistance, earth fault loop impedance, and disconnection times for every connected circuit in the property.
Electrical certificate
An Electrical Installation Certificate confirming the replacement meets BS 7671 wiring standards, accompanied by notification to local building control through NAPIT.
Clear next steps
Guidance on how to operate and test the RCD buttons periodically, along with recommendations if any existing circuit wiring requires future attention.

Why choose us

Use one local team for electrical inspection, diagnosis, installation and certification across homes, workplaces and light-industrial settings.

Fuse board questions

Common questions about replacing domestic fuse boards and upgrading to modern consumer units.

How long will my power be turned off during the replacement?+

I turn off the electricity supply once pre-testing is complete. The power remains off while I remove the old board, mount the new unit and terminate the circuits. I keep you informed during the outage and restore supply as soon as it is safe to test.

What happens if you find a fault with my existing wiring?+

I test your existing circuits before fitting the new board. If I uncover an underlying fault, such as damaged insulation or a bridged neutral, I will explain the issue clearly and discuss what is needed to resolve it before the circuit is re-energised.

Why do old fuse boards need replacing?+

Older fuse boards with wire fuses or early breakers cannot detect minor earth leakages quickly enough to prevent electric shocks. Modern units disconnect faulty circuits in milliseconds and use non-combustible metal enclosures.

Do I need to notify building control when changing a fuse board?+

Replacing a consumer unit is notifiable work under Part P of the Building Regulations. Because MX2 Electrical is NAPIT registered, we notify building control directly and provide your compliance certificate.

What space is needed around the new consumer unit?+

The new board must be accessible for maintenance, operation and testing. It should be mounted securely on a flat surface with sufficient clearance from gas meters and sources of heat or moisture.
