If your electricity meter is leaking, try not to panic. With a few simple checks, you can get the problem solved as quickly as possible.
If the leaking substance is hot
If there's a hot substance like black tar leaking in or around your electricity meter, and it has a strange smell, you need to phone your local network operator straight away on 105.
If the leaking substance is cold
If the leaking substance is cold and has no smell, call 105 free of charge to report this or contact your local network operator. Your local network operator owns the cables which run up to your meter where this issue normally occurs, even if they don't supply your electricity, so they'll be responsible for any issues with it.
Help with a gas leak
If you think you have a gas leak or can smell gas, phone the National Gas Emergencies number immediately on 0800 111 999. Only use a mobile phone from outside the property. If it's safe to do it, turn off your gas supply – the gas mains tap should be beside your gas meter. Move the handle a quarter turn until it's at 90 degrees from the pipe to shut off the gas supply.
