Expert Electricians in London

A kilowatt hour (kWh) is the amount of energy required to provide 1 kilowatt (1,000 watts) of electricity for one hour. A 100-watt light bulb burning for 1 hour uses 0.1 kWh. When the same bulb burns for 10 hours, it uses 1 kWh.

Use high efficiency light bulbs such as compact fluorescent bulbs in high use areas. They cost more to buy, but far less to use Turn off fluorescent bulbs if you will be out of the room more than 5 minutes Turn off incandescent bulbs every time you leave the room. Use only the lights you need Use a reading lamp or desk lamp for close work instead of a multi-bulb ceiling fixture.

The tiny wire filaments in light bulbs can be broken by vibration or high voltage. If regular bulbs burn out frequently, try using 230-volt incandescent bulbs or fluorescent bulbs.

Too many Brits are now using Google to search for tips or YouTube videos to help them carry out major DIY work, with almost half of all men admitting they feel a responsibility to try and tackle jobs themselves or ask a mate before calling a professional. In the survey conducted by Electrical Safety First it was found that almost half of all severe electric shocks are caused by DIY attempts, with the main errors including cutting through power leads, drilling into wiring in walls and repairing electrical items that are still switched on. In a survey of registered electricians, a third said they had seen or been involved with fixing DIY that had resulted in fires, serious electric shock or serious financial cost to repair.
