What to Expect When You Call Out an Electrician And, importantly, what not to expect!
Calling an electrician can sometimes feel like a fairly straightforward process.
You have a socket that isn’t working. A light keeps tripping. The cooker has stopped working. The RCD keeps going off. You call an electrician, they turn up, find the problem, fix it and leave.
Simple, right?
Well… sometimes.
Electrical faults have an annoying habit of not reading the script.
This guide explains what you can reasonably expect when you call out an electrician — and a few things you probably shouldn’t expect, no matter how many YouTube videos you’ve watched.
1. Expect the electrician to investigate the problem
If you report that “the sockets have stopped working”, the electrician’s first job is to establish why.
That may involve checking the consumer unit, testing circuits, carrying out dead tests, inspecting accessories, checking connections and potentially tracing the circuit.
It may take five minutes.
It may take considerably longer.
Finding a fault is not always a case of opening the nearest socket and discovering a loose wire sitting there waiting to be found.
Electrical systems are interconnected, and faults can occur in places that aren't immediately obvious.
So if your electrician spends some time testing rather than immediately announcing the answer, that's generally a good thing.
2. Don't expect the electrician to know what's wrong before they've looked
“I think it's the RCD.”
“It's definitely the socket.”
“My neighbour said it's probably the fuse.”
“I'm pretty sure it's just a loose connection.”
You may be right.
You may also have absolutely no idea.
And that's OK.
If you knew exactly what the fault was, you probably wouldn't have needed to call an electrician in the first place.
The electrician will diagnose the problem based on testing and inspection — not on the most convincing theory presented to them at the front door.
3. Expect testing to be part of the job
Testing isn't just something electricians do to make the visit look more impressive.
It's how we establish what is actually happening.
Depending on the fault, an electrician may need to test continuity, insulation resistance, polarity, earth fault loop impedance, RCD operation or other aspects of the installation.
Some faults can only be identified by eliminating possibilities.
Think of it like a detective investigation, except the suspect is usually a cable hidden behind a wall and nobody is particularly keen on giving it a statement.
4. Don't expect a guaranteed diagnosis within five minutes
Some faults are obvious.
Some are not.
A tripping circuit could be caused by an appliance, a damaged cable, water ingress, a faulty accessory, an insulation fault or a number of other issues.
If your electrician tells you that they need to investigate further, it doesn't necessarily mean they don't know what they're doing.
It may mean they don't want to guess.
And, frankly, you should prefer an electrician who tests rather than one who guesses confidently.
5. Expect the electrician to tell you when something needs replacing
Sometimes the correct repair is a repair. Sometimes the correct repair is replacement.
If a component is obsolete, damaged, unsafe, badly installed or no longer suitable for the installation, your electrician may recommend replacing it rather than attempting to keep it alive through sheer optimism.
That doesn't mean they're trying to sell you something.
Sometimes old electrical equipment really has reached the end of its useful life.
Your electrician should explain why replacement is being recommended and, where appropriate, give you options.
6. Don't expect us to repair something that shouldn't be repaired
There are occasions when a customer will say:
“But can't you just make it work?”
Technically, perhaps.
Should we?
That's a different question.
An electrician has a responsibility to carry out work safely and in accordance with the relevant requirements.
A temporary bodge that gets something working for another six months may not be a particularly good solution.
If an electrician refuses to carry out something they consider unsafe, that isn't them being difficult.
It's them doing their job properly.
7. Expect the price to reflect the work involved
A call-out charge doesn't necessarily mean you're paying someone simply to walk through your front door.
The cost may cover travel, time, equipment, testing, diagnosis, expertise, insurance, qualifications, certification, administration and the general cost of running a professional electrical business.
And yes — sometimes the electrician may attend, investigate for an hour and discover that the problem is a faulty appliance.
You may then quite reasonably ask:
“So what have I paid for?”
You've paid for the electrician to establish that the electrical installation isn't the cause of the problem.
That's still a diagnosis.
8. Don't expect a free diagnosis because you decide not to proceed
If you've instructed an electrician to attend and investigate a fault, the service has been provided whether or not you subsequently decide to have the recommended work carried out.
If the electrician spends time fault-finding and gives you a diagnosis, you can't reasonably expect that time to become free simply because you decide to get someone else to carry out the repair.
You're paying for the investigation and expertise — not just for the final repair.
9. Don't expect another contractor's quote to be identical
You may obtain another quote and discover that their recommendation is different.
That doesn't automatically mean one electrician is wrong.
Electrical faults can sometimes be approached in different ways, and contractors may identify different solutions based on what they have inspected, tested or been asked to quote for.
If another contractor tells you something completely different, the best thing to do is ask questions.
Don't simply assume that the cheapest quote is the correct one.
10. “My mate can do it cheaper” is not particularly useful information
We're all for saving money.
But electrical work isn't always an area where “a bloke who knows a bit about electrics” is the ideal benchmark.
A professional electrician has overheads, insurance, qualifications, test equipment, training and responsibilities.
If your mate can genuinely do the work properly, safely, legally and provide the appropriate certification, then that's a conversation for another day.
But comparing a professional electrical contractor with someone who owns a screwdriver isn't necessarily an apples-for-apples comparison.
11. Expect us to ask questions
If we ask:
“When did it start?”
“What happens when you reset the RCD?”
“Does it happen when a particular appliance is switched on?”
“Has any work been carried out recently?”
We're not making conversation.
We're gathering information.
Even small details can help narrow down a fault.
So if you don't know the answer, just say you don't know.
“It's always done that.”
“It's been like that since we moved in.”
“My husband normally deals with it.”
All perfectly acceptable answers.
We don't expect you to be an electrician.
That's why you called one.
12. Don't tell us how long the job should take
“This should only take 20 minutes.”
“It's literally just a socket.”
“You'll be done in no time.”
Possibly.
But we won't know until we investigate.
What appears to be a simple problem can uncover something completely different once we start testing.
The electrician isn't charging according to how easy the problem looks from the sofa.
13. Expect the electrician to explain what they've found
A good electrician should be able to explain the issue in straightforward language.
You shouldn't need a degree in electrical engineering to understand what you're being told.
If something needs repairing, replacing or further investigating, you should be given a reasonable explanation of why.
And if you don't understand something, ask.
We'd much rather explain it than have you nod politely and then Google it five minutes after we've left.
14. Don't expect us to sign off work we haven't carried out
This one comes up surprisingly often.
If another contractor has carried out work, we cannot simply inspect it for five minutes and certify it as our own.
Certification isn't a rubber stamp.
The person signing a certificate is taking responsibility for the work and the testing associated with it.
If we haven't carried out or properly assessed the work, we shouldn't be expected to certify it.
15. Finally: you don't have to agree with everything we recommend
You are perfectly entitled to ask questions.
You can ask why something needs doing.
You can ask whether there is another option.
You can ask for a quotation.
You can decide not to proceed.
That's completely reasonable.
What isn't particularly reasonable is instructing an electrician to investigate a problem, disregarding the diagnosis because it doesn't match what you expected to hear, getting another contractor to look at it and then expecting the original electrician to provide their time and expertise for free.
The Bottom Line
When you call an electrician, you're paying for knowledge, investigation, testing, experience and a professional opinion — not simply someone to turn up and agree with your diagnosis.
You don't need to understand electrics.
You don't need to know what an RCD does.
You don't need to know the difference between a fault and a faulty appliance.
And you certainly don't need to watch 14 YouTube videos before we arrive.
Just tell us what has happened, let us investigate it properly, ask questions if you're unsure, and we'll do our best to establish what is actually going on.
Because when it comes to electrical faults, “I reckon it's just…” is not a testing method.
