Get More Heat Hours For Your Money
WattsWatt is a public health service designed to help every household stay warm during winter by making your energy spend stretch further. In fact, we are on a mission to pump up to £4 billion more heat hours into Britain’s homes this winter, and every winter, to protect properties from damp and mould, and to protect the NHS from avoidable winter spikes.
WattsWatt was co-founded by public-health expert Lisa Malyon and is the UK’s first National Energy Service.
WattsWatt is a social-enterprise, meaning we exist to help society. We do this by guaranteeing that no household will ever overpay for energy again. Using smart-meter data, tariff transparency, and behavioural insights, WattsWatt helps families convert money into warmth more efficiently while tackling the health and financial toll of cold, damp housing.
"Out of 28 million households in the UK, 17.9 million households are on a standard variable tariff, which means they are overpaying by 5%-14% compared to the best value fixed tariff.
When you consider that 6.3 million households are classified as being fuel poor - if we made sure they were on the right tariff, we could pull many of these households out of fuel poverty."
Costing health and damaging housing stock
Collectively, these 17.9 million households are overpaying between £1.4 billion and £3.9 billion a year under the false protection of the price cap - almost equal to the £1.4 billion the NHS spends annually treating illnesses caused by poor indoor air quality. Both stem from the same national failure: cold, inefficient homes that cost lives as well as money.
