Consumer Unit (Fuse Box) Upgrades
Your consumer unit is the nerve centre of your home's electrical system. An outdated fuse board — especially one with rewireable fuses or a dual-RCD split-load — leaves your property exposed to risks that modern devices are specifically designed to prevent. We upgrade consumer units across Margate, Ramsgate, Broadstairs, and across all of Thanet.
Try the domestic consumer unit upgrade calculator for a line-item guide price (enclosure, RCBOs, SPD, and testing with our bundled rate) — then get a fixed quote to confirm.
Use it for the main board, or one small sub-board with 1–3 circuits (use the Secondary option). Several boards or a sub-board with 4+ circuits: we price after a visit — the online figure is not meant for that. Full technical & line-item article →
All work is completed to BS 7671:2018+A4:2026, the latest IET Wiring Regulations. On completion you receive a full Electrical Installation Certificate (EIC) and, where required, Building Regulations notification — so you're covered for property sales and landlord compliance.
Future-proof by default (domestic)
We fit a metal consumer unit with an RCBO on every circuit, surge protection (SPD), and spare capacity for an EV charger or other additions later. That is the up-to-date way to do it — not a stripped-back board that is only “compliant” on paper for a year or two.
We don’t compete on out-dated RCD or split-load shortcuts to hit a number. A quote that is dramatically lower is usually a softer, shorter-life layout. Like-for-like in Thanet, most who follow the same high standard we do are more expensive than us — not the other way round.
After a proper install, we’d love not to hear from you for a decade except for mandatory time-based testing (EICRs where the law says so) or new work you choose. That’s the idea of future-proofing.
Why It Matters
Premium Upgrade vs. Budget Install
Not all consumer unit upgrades are equal. Here's exactly what separates a proper installation from a cheap box-swap — and why the difference matters for your safety and your property value.
| Feature |
Premium RCBO Install Thanet Electrical Standard |
Budget Install Common cheaper approach |
|---|---|---|
| Protection Type | Individual RCBO per circuit | Dual-RCD (split-load) |
| Nuisance Tripping | Only the faulty circuit trips — rest stay on | Half the house loses power on a fault |
| Surge Protection (SPD) | Type 2 SPD fitted — required by Amendment 4 | Usually omitted to reduce cost |
| Enclosure Material | Metal-clad (required in rented properties) | Plastic (acceptable in owner-occupied only) |
| Regulation Compliance | Full BS 7671:2018+A4:2026 | May only meet older 18th Edition |
| Certification Issued | Full EIC + Building Regs notification | Minor Works only — insufficient for sales |
| Impact on Property Sale / Remortgage | Fully documented, no questions from solicitors | Can delay sale or fail surveyor checks |
| Guarantee | 12-month workmanship guarantee | Varies — often none in writing |
| Bottom Line | Safe, compliant, and future-proofed | Cheaper upfront, costly later |

What the Job Involves
Pre-work Survey
We inspect your existing installation, assess the number of circuits, earthing arrangement, and meter tails before quoting — no surprises on the day.
Safe Isolation & Swap
Power is isolated at the meter tails. The old unit is removed, the new board installed, all circuits reconnected, labelled, and tested before anything is energised.
Full Test & Inspect
Every circuit is tested to BS 7671 — insulation resistance, continuity, earth fault loop impedance, and RCD operation times all recorded on the certification.
EIC Issued Same Day
Your Electrical Installation Certificate is issued on completion. Building Regulations notification is submitted on your behalf where required — keeping your property legally compliant.
Get Your Free Quote
Tell us the number of circuits and your property type and we’ll come back with a written quote — usually the same day and more often than not within an hour — free, detailed, and with no obligation to proceed. If I’m working on live electrics it may take longer.
