FAQs
Why might a Bristol homeowner need an electrical panel upgrade?
Older fuse boards and small consumer units were designed for far lighter electrical loads than today’s homes demand. Upgrading to a modern 100- or 125-amp panel with RCBO or RCD protection ensures you have enough capacity for high-draw appliances (EV chargers, induction hobs, heat pumps, etc.), brings the installation up to current wiring regulations (BS 7671:18th Edition), and dramatically improves fire and shock protection. It also eliminates nuisance tripping and prepares the property for future renewable-energy connections.
What warning signs indicate my existing panel is overloaded or unsafe?
Common red flags include frequent breaker trips or blown fuses, warm or discoloured breaker fronts, a distinct buzzing or crackling from the board, lights that dim when appliances start, evidence of aluminum or rubber-sheathed cables, and a fuse box that lacks RCD protection. If you see any of these, schedule an inspection: our Bristol-based technicians can test the load balance and insulation resistance to confirm whether an upgrade is necessary.
How long will the upgrade take and will the power be off?
Most domestic panel replacements are completed within one working day. Power is usually isolated for 3–5 hours while the old board is removed, circuits are tested/labelled, and the new unit is installed and certified. We always discuss convenient dates, bring temporary lighting if needed, and can stagger critical circuits (e.g., fridge/freezer) onto a generator to minimise disruption.
Do I need planning permission or any paperwork when replacing a panel in Bristol?
Electrical panel upgrades inside a dwelling do not require planning permission, but they are classed as ‘notifiable works’ under Part P of the Building Regulations. As NICEIC Approved Contractors we notify Bristol City Council’s Building Control electronically the same day, and you receive: 1) an Electrical Installation Certificate, 2) a Part P compliance certificate, and 3) our six-year workmanship warranty.
What does a panel upgrade cost and what factors affect the price?
In Bristol, a straightforward 8–10-way consumer unit replacement starts around £480 + VAT, while large properties with 20+ circuits, surge protection devices, or three-phase supplies can reach £1,200–£1,600. Costs vary with panel size, earthing upgrades, cable extensions, remedial work on existing circuits, and optional extras such as SPD or AFDD modules. We provide a fixed quotation after a free site survey so there are no surprises.
Can a new electrical panel accommodate future tech like EV chargers, solar PV or a heat pump?
Absolutely. We specify boards with spare ways and higher busbar ratings so you can add 32–63 A circuits later without another full upgrade. We also fit Type 2 surge protection as standard, select MCBs/RCBOs that integrate with smart consumption monitoring, and leave space for micro-generation links so solar, battery storage, or an EV charger can connect safely whenever you’re ready.
