Gas firms fined £5.2m over leaks

Two major utility firms will be fined a combined £5.2 million for failing to attend potentially dangerous gas leaks on time, the energy watchdog has said.

National Grid Gas (NGG), which owns four networks in the UK, will be fined £4.3 million, while Northern Gas Networks (NGN), which owns one network in northern England, will be fined £900,000 for failing to hit targets for attending gas escapes on time last winter.
