Replace your old wire-fuse box or partial-RCD board with a full 18th-Edition RCBO consumer unit — safer, future-proof, and required for EV chargers.
From £875 (single-phase domestic). Same-day install most jobs. Certificate same day.
Your fuseboard is the heart of the electrical installation — if it's pre-2008 you almost certainly don't have RCDs (residual current devices) on every circuit, which means a fault on a damaged appliance can shock you before the breaker trips. The 18th-Edition (BS 7671:2018+A2:2022) requires RCBO protection on every individual circuit — that's the modern standard.
A consumer-unit upgrade typically takes 4-6 hours. We isolate at the meter, swap the old board for a new metal-clad RCBO consumer unit (no plastic boards anymore — current regs require non-combustible enclosure), test each circuit individually, label the breakers, and issue a Minor Electrical Installation Works Certificate (MEIWC) on completion.
You need an upgrade when: existing board has rewireable fuses (no breakers), no RCDs at all, RCD-only protection (single RCD covering multiple circuits — fail one, lose half), you're installing an EV charger (DNO requires a properly-protected supply), or your EICR has come back with C1/C2 codes against the consumer unit.
Send a photo of your existing fuseboard or call — we can quote in 2 minutes.
Written quote with chosen brand (Hager, MK Sentry, Wylex). Most domestic single-phase £875-£1,100.
Power off ~30 min, swap, test every circuit, label breakers, certify, hand over.
NAPIT MEIWC issued same day. Building Control notified automatically.
Notifiable work registered with Building Control automatically — you stay legal, certificate in hand.
All work installed to BS 7671:2018+A2:2022 — the currest 18th Edition Wiring Regulations (Amendment 3). Current UK standard for safe installation.
Quote in writing before work starts. Number on the quote = number on the invoice.

Bradford-based, working from Halifax to York and across the M62 corridor into Lancashire + Greater Manchester. We know the housing stock and the postcodes.
Most domestic single-phase upgrades take 4-6 hours. Power is off for around 30-60 minutes total — we run circuits live wherever possible. You're back fully running by tea time.
From £875 for a standard 6-way RCBO domestic unit (Hager / MK / Wylex). Larger 12+ way installs and metering complications can push to £850-£950. Always quoted fixed-price in writing.
Often yes. The DNO (district network operator) requires either a Type A RCBO on the EV circuit or a fully-RCBO consumer unit. If your existing board doesn't meet that, an upgrade is part of the EV charger install.
No — the meter belongs to your supplier and stays put. We work between the meter and the new consumer unit, not on the supplier side.
Yes — a brand-new 18th-Edition RCBO board is the gold standard. Your next EICR (5 years for landlord, 10 years for owner-occupier) will start with the consumer unit ticked off.
Yes. As NAPIT-registered we self-certify under the Building Regs. You get the NAPIT and Building Control paperwork by post within a few days.
