If a fault is causing heat, smoke, sparking, repeated tripping, or any sign of water getting into electrics, treat it as urgent and isolate the supply if it is safe to do so. If the problem is not dangerous and power is stable, it can usually be booked as a planned repair or fault-finding visit.
The key question is not just whether something is broken, but whether it could become dangerous before a normal appointment. In Costa Blanca homes and holiday properties, that often means deciding quickly between an emergency callout and a routine electrician visit.

Start with safety: what needs urgent attention
Call an electrician urgently when you notice any of the following: You may also find our Electrician in Sanet y Negrals useful.
- Smoke, burning smells, or visible scorching from sockets, switches, consumer units, appliances, or wiring
- Sparking that is repeated, strong, or coming from a fixed fitting rather than a plug-in appliance
- Heat from a socket, fuse board, cable, or plug that should only be warm at most
- Repeated tripping of a breaker or RCD, especially if it happens immediately after resetting
- Loss of all power to part or all of the property when there is no obvious simple cause
- Water exposure near electrical equipment, such as leaks, flooding, damp ingress, or rain reaching outdoor fittings
- Buzzing, crackling, or popping sounds from electrical equipment
- Shocks or tingles from appliances, switches, taps, or metalwork
If you can safely turn off the relevant circuit or isolate the property, do that while waiting for help. Do not keep resetting a breaker if it trips again straight away. You may also find our Hot Sockets, Burning Smells and Overheating Electrics useful.
When the fault can usually wait for a planned repair
A normal repair visit is often suitable when the issue is inconvenient but not showing warning signs of danger. Examples include: You may also find our Electrician in Costa Blanca South useful.
- One light fitting or socket not working, while the rest of the property is fine
- A faulty switch, lamp holder, or accessory with no heat, smell, or sparking
- An appliance problem that seems confined to that appliance
- Intermittent loss of power on one circuit without signs of overheating or water damage
- Replacing damaged fittings, broken faceplates, or worn components after they have already been made safe
Even when a fault seems minor, it is still worth arranging inspection if it keeps returning. Repeated nuisance faults can point to loose connections, ageing wiring, overloaded circuits, or moisture getting where it should not.
Why electrical faults become urgent
Electrical problems usually become urgent when one of three things is happening:
- Overheating — often shown by warmth, smell, discolouration, or melting
- Arc or short-circuit activity — often shown by sparking, crackling, or fast tripping
- Water intrusion or damage — which can make equipment unsafe even if it still appears to work
A fault that is only annoying can become a safety issue if the underlying cause worsens. That is why signs of heat, smoke, water, or repeated tripping matter more than the location of the problem.
What to do before the electrician arrives
If the fault looks urgent, these steps help keep people safe and make the visit more efficient:
- Switch off the affected circuit if it is safe to reach the consumer unit
- Unplug appliances on that circuit if you can do so without passing the fault
- Keep everyone away from smoking, sparking, or wet electrical equipment
- Do not use water on an electrical fire; use emergency services if there is a fire risk
- If there is flooding or a leak, stop using nearby sockets and fittings until checked
- Make a note of what happened just before the fault started
If the property is rented, empty, or used seasonally, tell the electrician whether anyone is on site and whether the power can be isolated before arrival.
Information that helps the visit go smoothly
When you request advice or arrange a callout, have these details ready:
- The type of fault: no power, tripping, sparking, smell, heat, water exposure, or another issue
- Where it is happening: kitchen, bathroom, outdoor area, consumer unit, extension, or specific room
- Whether it is affecting one circuit or the whole property
- What happened first and whether anything changed beforehand, such as rain, appliance use, DIY work, or a blown fuse
- Whether the property is occupied, vacant, or seasonal
- Any immediate safety steps already taken
Clear information helps an electrician judge whether the issue is likely to need an emergency visit or a normal repair appointment.
Choosing between emergency help and a planned visit
A simple rule helps:
- Emergency help if there is heat, smoke, sparking, water, repeated tripping, shocks, or a strong burning smell
- Planned repair if the fault is limited, stable, and not showing warning signs of danger
If you are unsure, it is better to ask for advice before using the circuit again. A quick conversation can prevent a small fault becoming a bigger one.

FAQ
Should I keep resetting a tripping breaker?
No. If it trips again straight away, stop resetting it and treat the fault as needing inspection. Repeated tripping usually means there is an underlying problem.
Is a burning smell always an emergency?
Yes, it should be treated seriously. Turn off the relevant circuit if it is safe, avoid using nearby equipment, and arrange urgent help.
What if the power is out but there is no visible danger?
A full or partial loss of power can be urgent if it affects safety systems or appears to come from the wiring rather than the wider supply. If you are unsure, ask for advice.
Is water near an electrical fitting always serious?
Yes. Water and electrics do not mix, and damp can make fittings unsafe even when they still seem to work.
Can I wait until morning if the fault seems minor?
Only if there are no warning signs such as heat, smell, sparking, water, or repeated tripping. If any of those are present, it should not wait.
Takeaway
Use urgency, not inconvenience, to decide. Heat, smoke, sparking, water, shocks, and repeated tripping call for immediate isolation and urgent help; isolated faults without danger signs can usually wait for a planned repair. If you are not sure which category your fault falls into, request advice and describe exactly what you have seen.
