Switching business energy providers can save money and reduce hassle, but a little preparation makes a big difference. Before you start comparing deals, there are a few things worth checking so the switch goes smoothly and there are no surprises later.

This guide walks through what to look at before you change supplier.

Check your current contract

Start with your most recent energy bill or contract paperwork.

You’re looking for:

• Your contract end date
• Any early exit fees
• The name of your current tariff

If you can’t find this information, your current supplier should be able to tell you quickly by phone or email.

Knowing where you stand helps you avoid switching too early and paying more than you need to.

Get the key details together

Having the right information ready means you’ll get more accurate quotes.

It helps to have:

• Your business address and postcode
• Annual energy usage in kWh
• Your MPAN number for electricity and MPRN number for gas
• Meter serial numbers
• Your current supplier and tariff name

If some details are missing, don’t worry. Suppliers can usually fill in gaps, but having most of it ready speeds things up.

Understand any exit fees

Most business energy contracts run for a fixed term. Some allow you to switch within a certain window near the end without a fee. Others charge for leaving early at any point.

If it’s not clear, ask directly when you can switch without paying extra. It’s better to know upfront than be caught out later.

Look beyond the headline price

The cheapest quote isn’t always the best deal.

When comparing providers, check:

• Unit rates per kWh
• Standing charges
• Contract length
• Payment terms
• Customer service reputation

A low unit rate can be offset by high standing charges, so it’s worth looking at the full cost over the contract term.

Read the terms carefully

Energy contracts often include details that are easy to miss.

Pay attention to:

• Automatic renewals
• Variable rates that can change during the contract
• Notice periods needed to cancel or switch

If something doesn’t make sense, ask the supplier to explain it clearly. You’re committing your business to the contract, so clarity matters.

If you rent your premises

If your business operates from rented space, check your lease.

Sometimes the tenant manages the energy contract. In other cases, it’s handled by the landlord or shared between businesses. Make sure responsibility is clear before switching to avoid confusion or duplicate bills.

Plan ahead

The best time to switch energy providers is usually a few months before your current contract ends. That gives you time to compare properly and avoids last minute decisions or rolling onto a default rate that’s rarely good value.

Even once you’ve switched, it’s worth reviewing your deal each year. Energy markets change and what worked last time may not be the best option next time.

Switching business energy doesn’t need to be stressful. A bit of preparation upfront helps you stay in control and choose a deal that actually works for your business.
