RCBO consumer unit after an emergency callout to investigate repeated tripping

Same-day electrical fault-finding for Northfleet homeowners, landlords, and letting agents. The fault profile we see most often: a circuit that’s dropped out and won’t reset, a socket that’s dead with nothing on the breaker tripped, a section of the property suddenly without power, or signs of arcing or overheating in the consumer unit. Triage on the phone first, then a callout where the fault actually warrants one. Working hours are Monday to Saturday with out-of-hours best-effort.

What Emergency actually is

Emergency work is reactive — something’s gone wrong and it needs sorting now (or now-ish). It’s the opposite of scheduled EICR or alarm install work, where the diary runs weeks ahead. For Northfleet emergency callouts the response is same-day where the diary allows, with a phone triage first to confirm the fault really needs a visit and to scope what’ll be needed. On site, the priority order is: make safe, diagnose, repair if parts and time allow, otherwise quote and book the return visit. Made-safe means the affected part of the installation is isolated so it can’t cause harm — even if the full repair happens later.

When you need Emergency in Northfleet

The triggers that bring most Northfleet emergency callouts: complete power loss (mains or partial), a circuit that keeps tripping the consumer unit, a dead socket or dead lighting circuit, signs of overheating (warm sockets, discolouration, smells from the consumer unit or fittings), and water ingress affecting an electrical fitting. Less common but real: shock from a metal appliance (suggesting earth fault or polarity issue, urgent), persistent flicker on lights across multiple circuits (suggesting loose neutral at the supply intake, urgent), and any fault that’s started after a recent storm or flood.

Standards and what compliance looks like

Emergency electrical work follows BS 7671:2018+A2:2022. The 18th Edition with Amendment 2 is the current reference for everything from socket replacement to consumer unit upgrades. Where an emergency fault is fixed on a callout, the repair is documented on a Minor Works or Installation Certificate confirming the work meets current standards. Beyond BS 7671, the practical standard on emergency work is “leave it safe and tell the customer the truth about what they’re looking at”. If the consumer unit is too old to take further remedials safely, we’ll say so; if a circuit is fundamentally damaged and needs replacing rather than patching, we’ll say that too.

Why Northfleet property owners book CJA Electrical

For Northfleet clients, the practical reasons CJA Electrical works on emergency electrical jobs come down to availability and trust. Availability — Rochester base means same-day reach is realistic, not theoretical. Trust — sole-trader operation, the person on the call is the person on site, the same person signs the certificate. No call-centre middle layer, no padded hourly rates, no upsell pressure on faults that don’t need it. Most emergency callouts to Northfleet are diagnosed and repaired on the same visit using van stock. For larger work uncovered during the visit (an end-of-life consumer unit, recircuiting needed on a damaged ring final), separate quoting happens after the made-safe action so the customer can decide.

How the work runs

Initial call is the triage — what’s happening, what’s affected, when did it start. From that we’ll either talk you through a safe reset (if it’s something the householder can do safely), book a same-day visit (if it’s a real fault), or schedule for the next working day (if it’s isolated and not urgent). On the visit, the priority is “is it safe?”. The affected circuit is isolated, the consumer unit checked, the fault diagnosed. Most faults are repaired on the same visit. For bigger jobs (consumer unit replacement, recircuiting) we quote and book a follow-up — the property is left safe in the meantime.

What affects the price

The factors that move emergency electrical pricing: time of day (working hours vs out-of-hours), distance (already covered by the 28-minute reach to Northfleet), and parts (whether the fix needs replacement components beyond standard van stock). Quote-up-front is standard — we won’t come out without first confirming the callout fee and the hourly rate. For larger follow-up work uncovered during the emergency visit (consumer unit replacement, recircuiting), separate quoting happens after the made-safe action so the householder has time to decide.

FAQs

Do you cover 24-hour emergencies?

Working hours are Monday to Saturday — within those, we aim for same-day where possible. Outside hours, it’s best-effort: call or WhatsApp and we’ll let you know honestly whether we can attend and how soon. We won’t promise something we can’t deliver.

Is there a callout fee?

Yes. The callout charge covers the visit and an initial block of labour; further work is hourly. Both numbers are confirmed up front before the visit so there are no surprises on the invoice. Out-of-hours callouts carry a small premium reflecting the time.

My RCD keeps tripping — is that an emergency?

Depends. A one-off trip that resets fine is usually a transient fault on an appliance — annoying but not dangerous. Repeated tripping (won’t reset, or trips again within minutes) means there’s a persistent fault on the circuit that needs diagnosing. Repeated tripping plus a burning smell or warm fitting needs same-day attention.

I can smell burning near the consumer unit — what should I do?

Turn off the main switch on the consumer unit immediately, then call us. Burning smells from the consumer unit are a same-day priority. The smell usually means a loose connection that’s been overheating, an end-of-life protective device, or (less commonly) a damaged cable entering the board. Don’t reset anything — leave the main switch off until we get there.

There’s no power at all — what should I check first?

Check whether your neighbours have power (rules out a supply-side outage). If they do, look at your main switch on the consumer unit — if it’s flipped to OFF, try resetting it once. If it trips again, leave it off and call us. If your neighbours are also off, it’s a UK Power Networks issue and worth ringing 105 first — we’ll only add cost on top of theirs.

Will you fix the fault on the same visit?

Most of the time, yes. Common faults — failed RCDs, dead sockets, isolated lighting circuits — are fixed on the callout visit with parts from van stock. Larger work (consumer unit replacement, recircuiting, significant cable damage) is quoted separately, with the property left safe in the meantime.

Can you sort the issue if it’s outside the consumer unit — like a meter problem?

Up to the meter is the supplier’s responsibility (UK Power Networks for Northfleet). From the meter inwards is the householder’s. If the fault traces back upstream of your consumer unit, we’ll diagnose it, confirm it’s a supply-side issue, and refer you on. There’s no charge beyond the callout for that diagnosis.
