RCBO consumer unit after an emergency callout to investigate repeated tripping

When the electrics fail at home, you want someone who’ll pick up and turn up. CJA Electrical covers Dartford for emergency callouts during working hours, with same-day visits the standard outcome when the diary’s got space. Dartford sits within 40 minutes of our Rochester base — close enough that response is genuinely quick, not “as soon as we can”.

What Emergency actually is

What separates an emergency electrical job from a scheduled one is timing — emergency work is “the fault’s already happened, fix it now”. Scheduled work is “we’d like this done in the next couple of weeks”. Emergency callouts in Dartford run on the triage-first model: 5-10 minutes on the phone to understand what’s actually wrong, then a same-day visit if the fault genuinely needs one. Common emergency outcomes: a tripped RCD that’s hiding a persistent fault (we diagnose and repair on the visit); a dead socket from a loose backbox connection (5-minute fix); an end-of-life consumer unit that’s started arcing internally (made safe on the day, full replacement quoted separately).

When you need Emergency in Dartford

The triggers that bring most Dartford 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

The technical reference for any emergency electrical repair is BS 7671 — the same Wiring Regulations that govern EICRs and new installations. Made-safe work is assessed against current standards even if the rest of the installation is older. Where a fault is symptomatic of a wider installation issue (the circuit that’s tripping is also missing RCD protection, or the consumer unit is end-of-life and unfit for additional remedial work), we’ll flag it transparently. The householder’s choice from there is whether to address the immediate fault only or take the opportunity to upgrade the wider installation.

Why Dartford property owners book CJA Electrical

The two things that matter on an emergency callout: speed (same-day, ideally same-morning) and honesty (genuine quotes on the spot, no padding, no manufactured “while we’re here” work). Both are why Dartford clients come back for non-emergency work after we’ve helped with an emergency. Operationally, the things that make emergency work fly: phone triage first (saves wasted callouts), full van stock for common faults (most jobs done in one visit), and clear pricing at booking (no surprises). All standard.

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

Emergency callout pricing is transparent: a callout charge covering the visit and the first chunk of labour, plus hourly thereafter for any further work. Both numbers are confirmed up front before the visit so there’s no surprise on the invoice. Parts are charged at trade cost-plus where needed. Out-of-hours callouts (evenings, Sundays) carry a small premium reflecting the inconvenient working time. We’ll confirm whether the visit is in-hours or out-of-hours when we book it. We don’t promise out-of-hours availability we can’t deliver — sometimes the honest answer is “first thing Monday” rather than “we’ll come now”.

FAQs

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 Dartford). 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.

Do you charge for the triage call?

No. The phone triage is free — we’d rather spend 10 minutes on the phone working out whether it’s a real callout or something resettable than send a van out for nothing. If a visit’s needed, the callout fee is confirmed before we leave; if it isn’t, you’re saved the cost.
