What is a business electricity contract?

A business electricity contract sets the unit rate (pence per kWh) and standing charge you pay for power at your premises, usually for a fixed term. When it ends, many suppliers move you onto a higher default rate. DNS Utilities compares options, arranges the switch and tracks your renewal date.

Common questions

Business electricity: 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. Compare options before your end date.

The MPAN is the number that identifies your electricity supply point. It appears on your bill and is what suppliers use to find your supply.

Your business name and address, your MPAN, 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 power.

Many suppliers offer renewable-backed tariffs. Availability and price vary, and we can show you the options.

Each site has its own meter point and contract, but we can compare and manage them together.
