for USA, Canada and countries running a 60 Hz supply service.
Call the utility company to check the supply to the house. If it is ok to the meter base and breaker panel, your house wiring is to blame
Ask the utility company to feel the transformer wiring connections. They can be extremely hot because of corrosion and this will cause flickering power sometimes.
Check the circuit breaker.
I had a friend who's lights were flickering. He had several people look into it. Electrician, Utility etc. No luck. We spent some time turning off breakers and we came to the realization that the circuit breaker's contact was bad. Replaced the breaker and voila no flicker.
Troubleshooting is the height of the art
The only reason there is "not enough voltage" somewhere is because there is a partially open connection providing resistance and a location to allow a voltage drop [bad splice, bad switch, bad breaker, broken wire, burned splice, ...].
It is the knowledge of how electricity works, and of the methods and materials used to create a functional wiring system, that enables a skilled troubleshooter to locate the problem and repair it.
Where should the "voltage" be, and how does it get there?
When you understand that, you will understand what is keeping it from getting where it should be...
As previously mentioned, a loose connection is often times the root of the problem. Are the lights in question all on the same circuit? If so, start at the panel and verify you have a solid connection to the breaker with the wire, and also from the breaker to the bus of the panel.
If all is good there, I would suggest looking in switch boxes for loose connections, starting at the one closest to the panel. Be sure to check both the hot splice and the neutral splice.
If all is good there, I would move on to the lighting boxes, again, starting at the light closest to the panel.
You may find as you do this, that the power is taken to the fixtures themselves, rather than to the switch boxes first. If this is the case, you may skip over the switch boxes.
Fixtures with non-dimmable compact flourescent lights will also flicker when put on a dimmer.
SAFETY FIRST: Turn off the breaker to minimize the risk of electrical shock!!

As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.
Before you do any work yourself,
on electrical circuits, equipment or appliances,
always use a test meter to ensure the circuit is, in fact, de-energized.

Most probably, a loose wiring connection.
So the electric lights and appliances in your house can work.
In a well designed house the lights are not connected to the same circuit as an appliance. If by going out you are saying that a breaker trips, then your appliances and lights combined are exceeding the rating of the breaker. You either need to rewire and balance the loads better or plug high current appliances into different outlets on another breaker. If you are not tripping breakers, but lights are just dimming you have a bigger problem with inadequate current supplying your house.

Lights in a home can flicker when the voltage received at the light is not staying stable. Two main causes: >the starting of machines or appliances with motors (like a refrigerator) and/or heating elements (like a laser printer)- the voltage dips when motors start, thus causing the lights to blink slightly. If even the smallest machines cause flickering, then the size of the wiring in the building may be too small. This is not dangerous but annoying. >Loose or arcing wire connections - this could be inside or outside the home. If outside it would be loose connections on the utilities companies wiring, and make the whole house flicker. If inside it would be somewhere in the house's wiring. **Arcing is a hazardous condition that can start fires.**
The circuit for the refrigerator is overloaded. The full size refrigerator typically requires a dedicated circuit.
Anything that uses a disc of some sort; stereos, DVD players and computers all use lasers.
they hate lights but they need a house with out the lights
Aluminum wiring in mobile homes often causes this problem. Also loose or corroded connections could be the cause. Power company transformer wire connections also corrode which can cause the problem. This is a potential fire hazard and should be checked immediately by a licensed electrician.
I have to assume by "vacuum" you mean the use of a vacuum cleaner causes the lights to flicker. If that is the situation, the flickering indicates that something is very wrong with the wiring in your home. It is not possible to properly and safely trouble shoot this problem via this Q & A system. I strongly suggest that you have this problem AND your home's electrical system fully checked out by a qualified AND properly LICENSED ELECTRICIAN.
