Who Supplies my Business Electricity & Gas?

21 December 2021

Although a fresh start can be exciting, moving business premises can be daunting. However, it’s important to determine who supplies your gas and electricity so you're on the best possible deal.

Even if you decide to stick with the supplier at your new business premises, you’ll need to let them know that you’ve moved into the building and provide them with up-to-date meter readings, so you’re billed correctly from the start.

In this guide, we provide practical information on how to find out which company is supplying gas and electricity to your premises, including useful contact information and advice on how to get the best deal at your new address.

Quick Navigation

Who is my gas supplier? 

One of the easiest ways to find out who supplies your business gas is to contact your landlord or the previous owner of the property. Often, these former tenants will leave bills behind, which you can also use to find out who your supplier is.

However, if this isn’t the case or if they’re unable to help you, you can call the Meter Number Helpline on 0870 608 1524. Before you call, you’ll need to have your Meter Point Reference Number (MPRN) handy, which is the unique gas supply reference for your meter. This is between six and ten numbers long and can be found on the property's gas meter. This is what the helpline will use to identify who your supplier is.

If you’re struggling to find this number, the Meter Number Helpline should be able to assist you with this, too. 

Who is my electricity supplier?

If you don’t have a previous electricity bill, you’ll need to contact the local distribution company. The UK electricity network is divided into large regions, each with its own local electricity distributor. To help you out, we’ve listed the contact information for all the country's regional distributors below.

If you’re not sure which region your premises is in, visit the Energy Networks Association (ENA) website and type your postcode into the network finder. This will provide you with all of the useful contact information you need to find your energy supplier.

What next? 

Once you’ve found out who your energy supplier is, you should assess whether you want to enter into a formal contract with them. While sticking with the same company may seem like an effective time-saver, you could find you save a substantial amount by switching.

At the very least, it’s wise to contact a few suppliers for an energy quote to ensure your business is being charged competitive energy prices.

What happens if I want to keep the same supplier? 

If you’re happy with the energy supplier at your current address and would prefer to stick with them after you’ve moved premises, you’ll need to tell your supplier before you leave your old address. They will set up an agreement at your new premises and you can contact the supplier at the new address to let them know you’re switching.

Consider comparing prices before you decide to stick with the same supplier, however, as the price you pay for energy will differ from property to property. For more help and advice, read our business energy guide for moving premises.

How to switch to a better business energy deal 

Switching from one energy company to another can also be quick, easy, and cost-effective – and won’t cause any disruption to your supply.

Step 1: Locate your energy contract or a copy of your most recent bill. The contract should tell you important information about your business energy rates and how to compare business energy prices per kWh when the contract ends.

You can start comparing and arranging a switch up to six months before the end of your contract. This gives you plenty of time to review different plans on the market to choose a provider that’s right for you.

Step 2: Start a quote and compare energy deals to find one that suits your business, factoring in any exit fees or other charges if you leave your provider.

Stay abreast of where you are in relation to your current energy contract – including what you’re paying and when it ends.

When comparing business energy details, you should keep the following in mind:

  • Your unit rates and standing charge
  • Your consumption, i.e., how much energy you use annually
  • Your meter numbers
  • Your contract end date
  • Your contract’s notice period

The unit rate is the price you pay per unit of energy (kWh), while the standing charge is a daily charge that helps with the maintenance of the national grid and the cost of transporting energy direct to your business.

Step 3: Once you’ve found a supplier you’re happy with, be sure to pay off any outstanding bills before you switch.

NB: Businesses have three options when it comes to comparing business energy deals: you can either contact the supplier directly to check rates, use a comparison site, or you can work through a business energy broker, who will take care of everything on behalf of the business.

Red flags to watch out for when switching energy supplier

There's a lot to weigh up when switching energy supplier. What might look like a great deal initially could end up costing you dearly down the line. Below, you'll find some of the biggest red flags you should keep in mind before you switch to a new energy supplier.

Don't be tempted by the cheapest offer

An energy tariff that's easy on the company coffers might seem tempting initially, but it's not always the most important factor. There's a host of other considerations to look at in addition to cost, so be sure to do a bit of extra research before deciding the cheapest option is right for your company.

Look at their customer service

A cheap energy deal isn't so attractive when you have to deal with the frustrations of unsatisfactory customer service. By checking reviews, you can get more of an idea of how they interact with their customers. Are they easy to get hold of, or will you have difficulty getting through to them? Are they transparent and honest or will they try to deceive you?

It might be worth paying a little more in the long run if you know you'll receive attentive customer service from them. And, luckily, there are plenty of energy suppliers who offer affordable prices and strong service to their customers.

Enquire about their green credentials

With Corporate Social Responsibility higher on the agendas of large businesses, greener options are an increasingly attractive and necessary element of business energy. A company with a green streak is a strong look, showing to customers, clients, and those in the local area that they're not simply motivated by the bottom line.

While green tariffs aren't always the cheapest, some suppliers might be able to offer certain perks, such as the option to offset your carbon footprint. And for a company looking to enhance their environmental authority, a higher tariff might be a small price to pay.

Be mindful of price comparison sites

While price comparison websites can be useful, they don't necessarily tell the whole story. For starters, not all suppliers advertise on there, so the overview of the market isn't as comprehensive as you might think.

Additionally, some of the information can be misleading. Supplier contracts are negotiated on a customer-by-customer basis, and so their prices don't consider factors like business size, location, sector, annual consumption, and credit rating, all of which can affect the final cost. In other words, they may show you the cheapest deal without some of the key details you need to make the right decision.

Watch out for rollover tariffs

When moving energy supplier, you should be wary of rollover tariffs. Many businesses have ended up rolling over onto new – and expensive – tariffs without realising. It's a costly issue for companies, who may find out they've been placed on one before they've had the chance to find a new energy supplier.

Although suppliers are required to give 60 days' notice before the end of the contract to prompt the customer, they don't always. A better approach would be to monitor the contract length yourself rather than relying on the supplier.

Make a note of when you're required to switch. This way, you'll have enough notice to re-negotiate or find a better deal elsewhere.
