How electrical fault finding pricing works
You get a fixed price for electrical fault finding in the Jack All Trades app before you book — no callout fee surprises, no open-ended hourly rates.
Tell JACK what is happening — a fuse board that keeps tripping, dead sockets, flickering lights — and when it started. A photo of your fuse board helps. You will have a fixed price in about two minutes, based on the fault you describe and the electrician or team who takes the job.
The price you accept covers the diagnostic visit, and most common faults are repaired on the spot. If the fix needs parts or follow-up work, your electrician explains exactly what is needed before anything extra is agreed.

Common electrical faults your electrician finds and fixes
Vetted electricians on Jack All Trades diagnose and repair the faults London homes see most, and most of them are fixed in the same visit.
- Fuse board or RCD that keeps tripping
- Dead sockets or a whole circuit down
- Flickering or dimming lights
- Burning smells or scorched sockets and switches
- Buzzing sockets, switches, or light fittings
- Partial power loss in part of the home
- Nuisance tripping after rain or a new appliance
- Outdoor and garden electrics faults
- Faulty light switches and pull cords
Is it an emergency?
A burning smell, scorching, sparking, or buzzing from any socket, switch, or your fuse board should be treated as urgent.
- Switch the affected circuit off at the fuse board if it is safe to reach
- Unplug appliances on that circuit and do not keep resetting a tripping switch
- If you see fire or smoke, call 999 first
- Book a same-day visit in the app and mention the symptom is urgent so it is prioritised
Frequently asked questions
How much does electrical fault finding cost in London?
There is no callout-plus-hourly guesswork on Jack All Trades. Describe the symptom in the app and JACK confirms a fixed price before you book, based on the fault and the electrician or team who takes the job.
How long does electrical fault finding take?
A fault with an obvious cause, like a tripping RCD from a faulty appliance, is often traced within the first hour. Intermittent faults can take longer. Your electrician explains what they find as they go.
My fuse box keeps tripping — what should I do first?
Unplug the appliances you used most recently and reset the switch once. If it trips again, leave it off and book an electrician — repeatedly resetting a tripping circuit can be dangerous.
Can the electrician fix the fault in the same visit?
Usually, yes. Most common faults — a damaged socket, a faulty switch, a failed light fitting — are repaired on the spot. If a part needs ordering, your electrician explains what is needed and can return to finish the job.
Are the electricians vetted?
Yes. Electrical work on Jack All Trades is carried out by vetted, insured local electricians, and you can see who is taking the job before they arrive.
Where do you cover?
All London boroughs, seven days a week, with same-day and evening slots often available.
What information helps the electrician before the visit?
The symptom, when it happens, what changed recently — a new appliance, building work, heavy rain — and a photo of your fuse board. Sharing this in the app means your electrician arrives ready to trace the fault.
Can I book a fault finding electrician for the same day?
Yes. Same-day slots are often available across London, including evenings and weekends. Describe the symptom in the app and pick the earliest slot that works.
Do you handle intermittent faults?
Yes. Intermittent faults — lights that flicker occasionally or a circuit that trips every few days — take more tracing, so note when the problem appears. Your electrician tests the likely circuits and explains what they find.
