Flickering lights is a relatively common issue and do not always indicate a problem with your electrical system. If your lighting flickers in your home or office there are a variety of explanations, here are the main causes below and how to address them:
If a single light bulb is flickering, it’s likely that it’s the bulb causing the issue. You can check to make sure the bulb is secured properly in the fitting (always make sure you switch the light off before doing this to stay safe). If a bulb isn’t secured properly then this can cause a flicker as it’s not connected correctly. If you find the light still flickers when it’s switched back on it could mean that the particular bulb needs to be replaced as it’s at the end of its lifespan.
