A water company says it is experiencing its most difficult winter on record, with daily customer calls up 400% compared with previous years.
Anglia Water operates in Essex, Herts, Norfolk, Suffolk, Cambridgeshire, Northampton and Milton Keynes.
A spokesman said there had been a sharp rise in frozen and burst pipes and other weather-related issues.
"On exceptionally cold days, we're taking up to 400% more calls than we'd expect," he said.
The increased demand has escalated in the past three weeks.
"Typically, we'd take around 26,000 calls over this period," he added.
"In fact, we've taken about 46,500 - about 80% more than we would expect.
"It wouldn't be an exaggeration to say that we're dealing with the toughest start to winter that we've ever experienced."
He added that Anglian Water was grateful to its customers who were showing "considerable understanding".
