How business gas is priced
Like electricity, business gas is charged as a unit rate per kWh plus a daily standing charge. Gas meters record volume, which suppliers convert into kWh using a calorific value. Your price also depends on your annual quantity (AQ), the network's estimate of how much gas your site uses in a year.
Because heating drives most gas use, bills often swing between summer and winter. A fixed contract smooths out price risk, while monthly payments based on your real usage avoid surprises.
Business gas contract options
| Contract | Best for | Things to know |
|---|---|---|
| Fixed term (1–5 years) | Most businesses | Unit rate and standing charge stay the same for the term |
| Flexible | Very high gas users | Gas is bought in tranches; needs active management |
| Out of contract / deemed | No one, if avoidable | Applies when a contract ends or you move in; usually higher |

Gas meter types
- Standard credit meters — Read manually or estimated. Submit readings regularly to avoid estimated bills.
- AMR (automatic meter reading) — Sends readings automatically. Common for medium and larger users.
- Smart gas meters — Send readings automatically and support accurate monthly billing.
Finding your MPRN
Your Meter Point Reference Number (MPRN) identifies your gas supply. It's usually 6 to 10 digits and printed on your gas bill, sometimes labelled "M number". Adding it to your quote request helps us confirm your AQ and price accurately.
Who uses business gas the most?
Restaurants, takeaways and pubs, bakeries, hotels and B&Bs, care homes, schools, garages and workshops with gas heating, laundrettes, manufacturers and any premises with gas-fired heating.
Practical ways to manage business gas costs
- Lock in a fixed price before winter if budgeting matters most.
- Service boilers and check controls and timers so heating runs only when needed.
- Provide regular readings, or ask about AMR or smart meters, to end estimated bills.
- Review your contract at least six months before it ends.
