With households wanting to keep their bills down, many are limiting how much they use the central heating. But a cold home can soon become a damp home, especially when you're hanging washing to dry inside too.
Damp expert Richard Brown says the recent coroner's ruling that two-year-old Awaab Ishak was killed by breathing in mould - in his family's one-bedroom flat in Rochdale - shows how serious the problem can be.
"Up until the coroner made that judgement, it had always been assumed," he said. "No coroner had ever actually took that step and categorically stated this item has killed - and unfortunately it's a two-year-old that's been affected this time."
