What is a business gas contract?

A business gas contract is an agreement with a supplier for the price you pay per kWh of gas, usually for a fixed term of one to five years. If it ends and you have not agreed a new one, many suppliers move you onto a more expensive default rate. DNS Utilities compares contracts, arranges the switch and tracks your end date.

Common questions

Business gas: your questions answered

If you have not agreed a new contract, many suppliers move you onto a default rate, which is often higher than a negotiated one. Check your end date and compare options before it arrives.

Many businesses start a few months before their contract ends. Check your contract for any notice period, as some require notice before the end date.

Your business name and address, your MPRN (meter point reference number, shown on your bill), your annual usage if you have it, and your contract end date. A recent bill covers most of this.

No. Switching changes who bills you, not the physical supply. The same network and meter continue to deliver your gas.

You usually cannot leave a fixed-term contract early without paying exit charges. Often the better route is to line up your next contract to start when the current one ends. We can check your terms with you.

If the premises uses gas, for cooking, heating or hot water, yes. When you take over a site with no contract in place you are typically placed on a default rate, so it is worth arranging a contract as early as possible.
