THE ENERGY INTERVIEW
Since the UK’ s cost of living crisis began in late 2021, the British public’ s annual energy bills have risen by 45 %. The story has been much the same across Europe and the rest of the world, with Russia’ s invasion of Ukraine disrupting global energy supplies and pushing prices sky high. As a result, energy has become a pressing concern for millions of people in the UK and beyond.
It is in this context that Octopus Energy, the UK’ s leading energy provider, has been developing perhaps its most ground-breaking initiative to date: homes with no energy bills whatsoever.
Not reduced bills, not subsidised bills, but genuinely zero bills for up to a decade.
The concept, aptly named Zero Bills, represents what Nigel Banks, the company’ s Technical Director of Zero Bills & Low-Carbon Homes, describes as a“ world-leading smart tariff” that is transforming how we think about domestic energy consumption.
How Zero Bills works The premise is elegantly simple: homeowners pay nothing for the energy they import, receive no payment for energy they export and pay no standing charge. It is, as Nigel is keen to emphasise,“ truly a zero energy bill”.
However, achieving this requires meeting specific technical criteria. Homes must be all-electric, typically featuring a heat pump for heating and hot water, a fairly substantial solar array and a relatively large home battery to store generated electricity.
In essence, for a home to be eligible for a Zero Bills tariff, it needs to generate slightly more energy than it uses.
“ We typically need to generate slightly more energy than the home is using and we also need to smart control that energy,” Nigel explains.“ The battery, the EV charger and in most cases the heat pump are then intelligently controlled by Octopus Energy but very much in line with the customer’ s preferences.”
The tariff includes a Fair Use Allowance of 10 MWh per year, which is roughly double the electricity a typical household uses. EV charging is also separately billed through Octopus’ s intelligent charging tariff. But for everyday energy needs, the bill genuinely reads zero.
