We help households understand how their gas is charged, what their readings show, and what the contract terms on offer really mean before deciding whether to change anything.
Seasonal usage explained
Why winter consumption changes your bill so much.
Readings and estimates
How estimated bills work and when to submit a reading.
Clear contract terms
Fixed terms, exit fees and what happens at the end.
How household gas is charged
Gas is billed in kilowatt hours. The meter records volume, and the supplier converts that to energy using a calculation that accounts for the calorific value of the gas in your area. As with electricity, your bill combines a unit rate with a standing charge.
Where gas and electricity are purchased together as a dual fuel account, one supplier handles both bills. Dual fuel is convenient, but it does not automatically mean the cheapest combination: it is worth checking whether a separate arrangement for each fuel would suit you better.
- Unit rates may change with consumption on some tariffs.
- Standing charges apply every day, including through the summer.
- Dual fuel means one supplier and one bill, but not necessarily the lowest cost.
Readings, estimates and disputed bills
If a supplier does not receive a reading, the bill is estimated from previous use. Estimates can drift, particularly after a change in the household or a cold snap, and a run of estimates followed by an actual reading often produces an unexpectedly large bill.
Submitting regular readings, or having a smart meter that does it automatically, keeps bills aligned with actual consumption. If a bill looks wrong, the reading, the period covered and the meter details are the first things to check.
Boilers, appliances and usage
Most household gas is used for heating and hot water, so small changes to how a system is run can affect consumption over a winter. We can explain what typically drives consumption and what to look at when usage changes without an obvious explanation.
- Heating controls, thermostats and timer settings.
- Boiler servicing and whether the appliance is operating efficiently.
- Insulation and draughts, which affect how long heating runs.
- Whether gas appliances other than the boiler, such as a hob or fire, contribute significantly.
Who we help with domestic gas
Support for households wanting clarity on gas bills and the options available to them.
- Homeowners approaching the end of a fixed term
- Tenants responsible for the gas account
- Households on a dual fuel tariff wanting a review
- Homes heated by gas with high winter consumption
- Households receiving estimated bills
- Anyone with a gas bill that has changed unexpectedly
Eligibility and what to expect
Available gas tariffs depend on your meter, payment method and region, and on supplier criteria. Gas safety work, boiler repairs and servicing are carried out by registered Gas Safe engineers, which is a separate service from anything we provide.
