Is My Bill Fair discount codes, October 2026

ismybillfair is a free bill-checking service for UK households, run by Nineteen21 Limited, a London company authorised and regulated by the Financial Conduct Authority. Its angle is different from a standard comparison site: rather than pushing you to switch, it tries to get you a fairer price from the supplier you already use, so you keep the same account and service. It says more than 6.8 million people have checked their bills with it.

It covers household energy from suppliers including British Gas, E.ON Next, EDF, Octopus Energy, OVO Energy and Scottish Power, plus business energy; broadband from BT, Sky, Virgin Media and Vodafone; and insurance including car, home, travel, van, pet, motorbike, bicycle and breakdown cover. You answer a few questions about your bill and provider, and it shows your options, usually in under a minute. Where switching is the only way to a better price, it tells you before you do anything.

It suits anyone who suspects they're overpaying but doesn't want the hassle of changing supplier. Checking is free and doesn't involve a credit check, and if you're already on a fair price it says so. The company is paid by the provider if you accept a deal. Renters can use it where the bill is in their name, and there's a page pointing people who are struggling to pay towards support.
