From: > 59% of dwellings in 2019 used their central heating system to provide hot water without a separate cylinder. Around a third (32%) used their central heating system to provide hot water through a separate hot water cylinder, 7% had a hot water cylinder and immersion heater as the primary means of water heating and less than two percent had an instantaneous water heater or dedicated boiler (1% and 0.2%, respectively) So about 40% have hot water tanks, though I guess the number is falling.
