The board everything else depends on

An outdated consumer unit isn't just an old fuse box — it's incompatible with modern solar, battery, and EV setups, and it creates compliance and insurance headaches. We supply and fit 18th Edition boards with surge protection and solar-ready circuits.

The Foundation
Get the board right, everything else follows

Solar, storage, and EV charging all connect through your consumer unit. If it's an older board, it likely can't accommodate them safely or compliantly — and a non-compliant board can complicate both your installation sign-off and your home insurance.

We fit 18th Edition compliant units as standard. That means RCBO protection on every circuit — so a single fault isolates one circuit rather than tripping the whole house — and a surge protection device (SPD) at the board, protecting the entire property.

We add dedicated circuits for generation meters, batteries, EV chargers, and smart devices, and notify all work to Building Control under Part P. It's the unglamorous part of a good install — and the part everything else depends on.

Clean changeover

A tidy, planned swap with minimal disruption to your supply.

A board upgrade comes with

The compliant, future-ready base layer for solar, storage, and EV charging.

  • Assessment of your existing board and its suitability for solar and storage.
  • 18th Edition consumer unit supplied and fitted to current regulations.
  • RCBO protection per circuit for independent, circuit-level fault isolation.
  • Surge protection device (SPD) fitted at the board for whole-home cover.
  • Dedicated solar / battery / EV ways provisioned for now and later.
  • Part P notification & certification handled and documented on completion.

Old fuse box? Let's assess it.

If your board predates RCBOs and SPDs, it's worth a look before any solar or EV work. We'll tell you plainly whether it needs replacing.
