What are the differences between domestic and business energy suppliers?
Some companies supply both home and business energy, but there are important differences:

• Price Caps: Business energy suppliers don’t have a price cap like home energy suppliers do, so their standard rates can be higher.
• VAT: Business energy suppliers charge 20% VAT, while home energy suppliers charge 5%.
• Climate Change Levy: Business energy bills include an extra charge for the climate change levy.
• Dual-Fuel Products: Home energy suppliers often offer combined gas and electricity deals, but business energy suppliers usually offer them separately.

What are the benefits of using an energy broker to find a commercial energy supplier?

Using an energy broker can help businesses find cheaper energy deals quickly and easily. To help you decide if a broker is right for you, we’ve created a guide on business energy brokers. The guide covers:

• How business energy brokers work
• How brokers get paid
• Whether a broker is a good choice for you

Can I negotiate prices with my business energy supplier?
It depends. If you’re under contract with your current supplier, you usually can’t negotiate rates until the contract ends. But if you’re not under contract and paying standard rates, you can negotiate. Standard rates are often high, and your supplier might offer you a cheaper fixed rate instead.

To get the best deal, try negotiating with your current supplier and comparing rates from different suppliers.

What’s the difference between a business energy supplier and a distributor?
Business energy suppliers and distributors have different roles:

• Distributors: They own and manage the local network of powerlines, cables, and substations. Their job is to carry electricity from the National Grid to homes and businesses in your area.
• Suppliers: They buy electricity in bulk from the wholesale market and then pay distributors to deliver it to your business.
