About Bills Estimator UK
Our Mission
Bills Estimator UK helps UK households understand and budget for their utility costs using the latest Ofgem data. Whether you're moving into a new property, planning your household budget, or simply want to check whether your current bills are in line with the national average, our free estimator gives you a clear picture in seconds.
What We Do
Our bills estimator calculates estimated monthly and annual costs for the three main UK household utilities:
- •Gas — based on Ofgem price cap unit rates and standing charges
- •Electricity — adjusted for property type, occupancy, and heating method
- •Water & sewerage — with support for both metered and unmetered properties
Estimates are updated quarterly when Ofgem sets the new energy price cap, ensuring the figures you see reflect current rates.
What We Don't Do
Bills Estimator UK is not an energy switching service, price comparison site, or financial adviser. We do not:
- ✗Sell energy tariffs or arrange supplier switches
- ✗Provide financial, tax, or investment advice
- ✗Collect or store personal data — the estimator runs entirely in your browser
- ✗Receive commission or referral fees from energy companies
Accuracy & Transparency
We aim for transparency in how our estimates are produced. Our methodology page explains our data sources, calculation method, update schedule, and the limitations of our estimates. A typical variance of 15-25% from actual bills is normal, as individual consumption depends on factors like insulation, appliance efficiency, and personal habits that we cannot model.
