Don't let your electricity contract renew itself.
Quietly rolling over is how businesses end up on expensive rates. We compare business electricity tariffs, handle the switch and watch your renewal date, for one site or many.
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.

What is on your business electricity bill?
| Charge | What it is |
|---|---|
| Unit rate | What you pay for each kWh of electricity you use |
| Standing charge | A fixed daily charge for being connected, whatever you use |
| Network and policy costs | Costs for moving power to your site and for environmental schemes, often passed through by your supplier |
| Climate Change Levy | A tax on business energy use. Some businesses qualify for a discount or exemption |
| VAT | Charged on your bill. A reduced rate can apply to very small users |
A general guide. Your bill may show other items.

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.
