In detail: Energy Bill Split Calculator for a £100 Bill split between 3 People
Splitting a £100 energy bill 3 ways at £33.33 each works cleanly only if usage is roughly equal. In reality, the person who works from home, runs the tumble dryer, or takes longer showers drives disproportionate usage — worth having an open conversation rather than assuming strict equality is fair.
A £100 monthly bill for 3 people is below the UK average — either the property is small, well-insulated, or everyone is out of the house during the day. Worth checking that the direct debit isn't under-estimated; ending the year with a big shortfall is a common nasty surprise.
For houseshares, the fairest setup is often a shared account with everyone paying a fixed monthly contribution that's reconciled quarterly against actuals — avoids arguments and catches meter-reading errors early.
