RCBO consumer unit after an emergency callout to investigate repeated tripping

Emergency electrical work in Dover — no power, repeated tripping, a dead circuit, a socket making popping sounds, a burning smell coming from the consumer unit. CJA Electrical triages the fault on the phone first (sometimes the fix is something the householder can do safely without a callout), then attends same-day where possible to make the installation safe. Full repair is quoted separately once the fault’s understood.

What Emergency actually is

Most Dover emergency callouts split into a few categories. Power failures — total or partial — usually trace back to a tripped main switch, a failed RCD, or (less commonly) a supplier-side issue we’ll diagnose and refer on. Repeated tripping points to a faulty appliance, a deteriorating cable, or moisture ingress somewhere on the affected circuit. Burning smells and overheating point to loose connections or end-of-life accessories. The triage call up front saves time on both sides. We’ll ask questions over the phone — when did it start, what’s affected, what’s been tried — and very often that’s enough to either fix the problem remotely or scope what we’ll need on the visit.

When you need Emergency in Dover

The honest triage question on any potential emergency is “is it safe to leave overnight?” If there’s a burning smell, overheating fitting, water near electrics, or shock from an appliance — no, same-day visit needed. If a circuit’s tripped and won’t reset, the affected part of the installation is already isolated and it’s usually safe to leave until the next working morning. For Dover clients, that triage call saves time and money — most callouts that turn out to be “tripped RCD that resets fine” can be handled over the phone without a visit. Where a real fault is present, the visit is scheduled same-day or first thing next morning.

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 Dover 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 Dover 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

The factors that move emergency electrical pricing: time of day (working hours vs out-of-hours), distance (already covered by the 90-minute reach to Dover), 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

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 Dover). 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.

Will the fix come with a certificate?

For any work that involves new circuits or significant changes to the installation, yes — a Minor Works or Installation Certificate is supplied documenting the work. For straightforward fault diagnosis and repair (replacing a failed RCD, swapping a damaged socket), the work is documented on the invoice rather than a separate certificate.
