Before you call an electrician in Croydon: safe checks to do first

A good proportion of calls to an electrician in Croydon end with a reset, an unplugged appliance or a replaced bulb, and a bill for the minimum charge. Some checks are entirely safe for a householder to do, and doing them first either solves the problem or gives the electrician the information they need to arrive with the right parts. This guide sets out what you can check without touching any wiring, what you must never do, and what to have ready when you ring.

Checks you can safely do first

A single socket or light has stopped working

Try the appliance in another socket to rule out the appliance itself. Check the fuse in the plug; a fuse that keeps blowing points to the appliance, not the house. For a light, change the bulb and, if it is a lamp, try it in a different socket. Many modern LED bulbs fail suddenly rather than fading, and a dead downlight is more often a bulb or a built-in driver than a wiring fault.

Everything on one circuit is off

Open the consumer unit flap (the small hinged cover over the switches, not the main cover) and look for a breaker that is down, or sitting between on and off. Switch it fully off, then back on. If an RCD has tripped, reset it. If it trips again immediately, unplug everything on that circuit and try once more. If it holds, plug appliances back in one at a time until you find the culprit. If it trips with nothing plugged in, stop; that is a wiring fault.

The whole house is off

Look out of the window. If the street is dark, call 105, the national power cut line, which routes you to UK Power Networks for Croydon. If the neighbours have power, check the main switch on your consumer unit. If it is on and you still have nothing, the fault may be at the cut-out or meter, which belong to the network operator and are not yours to touch. Call 105 and report it as a loss of supply.

A smell, a buzz or heat

These are not things to investigate. Switch the circuit off at the consumer unit, leave it off, and call. A warm socket faceplate, a buzzing dimmer or a fishy or burning smell near electrics are the early signs of a loose connection or an overloaded terminal, and these cause house fires.

What you must never do

• Remove the main cover of the consumer unit. Live parts are exposed behind it.
• Open a socket, switch or ceiling rose to look inside, even with the circuit off, unless you know how to prove it dead.
• Reset a breaker repeatedly to keep the lights on. Each trip is a warning.
• Tape over a damaged cable or extension lead as a fix.
• Use a four-way extension to run heaters, tumble dryers or anything else drawing a high current.

Information to have ready when you call electricians in Croydon

1. What happened, in order: what was switched on, what tripped, what you have already tried.
2. A photo of the consumer unit with the flap open, showing the labels. The electrician can tell at a glance whether it has RCDs and roughly how old it is.
3. The age of the property and whether it has been rewired, if you know.
4. Say if you own, rent or lease the home. Tenants should report faults to the landlord or agent first; the landlord is responsible for the installation under the Landlord and Tenant Act 1985.
5. Access: where the consumer unit is, whether there is parking, and when someone will be in.
6. Any existing paperwork, such as an EICR or an electrical installation certificate from recent work.

With that information, a local electrician can usually tell you whether the job is a same-day emergency, a routine visit or something that needs a longer appointment, and can give you a realistic quote rather than a guess.

What is different in Croydon

Croydon has a large stock of 1930s semis, particularly across Shirley, Purley, Coulsdon and Addiscombe, together with Victorian terraces in the older areas near West Croydon and Thornton Heath, and a growing number of town-centre flats in converted office blocks and new towers. The 1930s houses deserve a particular word: many had a partial rewire decades ago, and it is common to find a modern consumer unit feeding a mix of newer cable and original lighting circuits with no earth. That combination is why an RCD may trip on the lighting when a metal light fitting is installed. In the town-centre conversions, consumer units are sometimes in awkward places and the supply arrangements can be unusual, so photographs help.

Croydon Council building control receives Part P notifications for the borough, and the council’s private sector housing team enforces the electrical safety rules that apply to rented homes. Parking on the suburban streets is generally straightforward; in the town centre and near East Croydon station it is not, so mention it when you book.

When to call a professional

Anything that involves opening the installation is work for a registered electrician. New circuits, consumer unit changes and bathroom work are notifiable under Part P of the Building Regulations in England and should be done by someone registered with NICEIC, NAPIT or a similar competent person scheme. Croydon electricians who are registered will certify the work and notify the council for you. If the house predates 2000, asbestos may be present in old fuse board backing boards and textured ceilings, so do not drill or sand near them. If a fault followed a water leak, isolate the circuit and deal with the water first.

Once you have done the checks above and the problem persists, describe what you found and your postcode to The Household Daily’s help desk and we will help you take the next step towards an electrician in Croydon.
