A rewire is necessary when an electrical installation comes to the end of its life; this may be after many decades of use and would be determined through inspection and testing. As rewires normally involve chasing channels in walls for cables and lifting up floorboards they are usually carried out when the property owner is not living there. Ally Electrical Services Ltd often carries out rewires for customers that have just bought a property and want the electrics fixed before they move in. If you are living in the property but need a rewire, well, this would be an ideal time to go on holiday! If you have halogen downlights in your home replacing them with energy saving LED downlights would dramatically reduce your electricity bills (the average LED bulb uses 10% of the power a halogen uses). Some halogen downlights can be replaced by the householder but those with transformers above the ceiling will need an electrician to replace them. You can tell by looking at the bulb. If it fixes to the lamp holder above with two thin pins it uses a transformer and will need an electrician to change it to a LED fitting. We can advise the best way to alter your downlights during a site visit.
