RCBO consumer unit after an emergency callout to investigate repeated tripping

CJA Electrical handles emergency electrical callouts across Longfield and the wider Dartford area — power off, circuits tripping, sockets dead, burning smells, partial supply loss, and the kind of fault you don’t want to leave overnight. Working hours are Monday to Saturday with same-day visits where the diary allows; outside hours it’s best-effort. Call or WhatsApp first — most faults can be triaged on the phone before any callout is needed.

What Emergency actually is

Most Longfield 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 Longfield

Some faults are emergencies, some can wait. Real emergencies: burning smells, overheating fittings, shock from appliances, water ingress to electrical kit, any fault on a critical circuit (heating in winter, fridge/freezer load). Less urgent but still worth booking promptly: a single dead socket on a non-critical circuit, an outdoor light circuit that’s failed, a doorbell that’s stopped working, a recurring nuisance trip you can reset. The triage call sorts which is which. Working hours are Mon-Sat with same-day where the diary allows; outside hours it’s best-effort. We won’t promise a callout we can’t deliver.

Standards and what compliance looks like

Emergency repairs are made to the same BS 7671:2018+A2:2022 standard as any other electrical work. Made-safe action on a callout is exactly that — temporary isolation of the affected circuit so it can’t cause harm — but the eventual repair has to bring the installation back into compliance with the current Wiring Regulations. For older Longfield property where the original installation pre-dates current standards, repairs sometimes uncover secondary issues (lighting circuits without earth, undersized consumer units, missing RCD protection) that aren’t strictly part of the emergency but are flagged on the visit so the householder can decide whether to address them.

Why Longfield property owners book CJA Electrical

CJA Electrical is based in Rochester and covers emergency electrical work across Dartford from there. Longfield sits within a 30-minute drive, which means same-day callouts are genuinely deliverable rather than aspirational. The work is done by someone qualified to City & Guilds 2391 (Inspection & Testing), 2382 (18th Edition Wiring Regulations), and 2365 (Diploma in Electrical Installation). On site, the priority is making the property safe before anything else. Full repair happens on the same visit if parts and time allow; otherwise it’s quoted and scheduled. No surprises on the invoice — callout charges and labour rates are confirmed up front before the visit.

How the work runs

Step one — call or WhatsApp with what’s happening. Phone number, address, the nature of the fault, when it started, what’s affected. We’ll triage on the phone first — sometimes the fix is something the householder can do safely without a callout (resetting a tripped RCD, checking the main switch), and that’s worth knowing before you spend on a visit. Step two — the callout. Same-day where the diary allows, first-thing next morning otherwise. We’ll confirm the callout charge and any minimum labour up front before the visit. On site, the first action is making the property safe; diagnosis and repair follow from there. Step three — the repair. Most faults are sorted on the same visit. Where parts are needed or the work’s larger than a single-visit fix, we’ll quote and book the return.

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

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.

How quickly can you get to me?

Same-day where the diary allows. Working hours are Monday to Saturday. Call or WhatsApp first with what’s happening — we’ll triage on the phone, then either talk you through a safe reset, book a same-day visit, or schedule for the next working morning depending on what the fault is.

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.
