How to find out who supplies your business energy

You might not know where to start if you’re looking to find out who your gas and electric suppliers are.

Here, we will give you an informative guide with all the information you need to check who your current energy suppliers are. It’s important to find out your gas and electric suppliers to ensure their energy deals are right for you.

Who supplies your energy? Why is it important?

Sometimes, you just might not have information on who is supplying your business energy. For instance, you might have just moved offices or into new commercial premises. In most cases, you won’t know who is supplying your gas and electricity until your bill is due.

What’s the problem with waiting for your energy bill?

It might not sound like anything major, but there are issues with waiting for a bill to check who your energy supplier is. For example, you could end up paying for business energy that you didn’t consume from previous occupants.

Another point to consider is whether you’re on a ‘deemed contract’ with the previous occupant’s energy supplier. This is most likely the case, until you arrange a new business energy contract at your new site.

A deemed contract typically starts when businesses move into new premises and consume gas, electricity, or both, without agreeing a contract with a supplier.

Around 10 per cent of micro-businesses are on deemed contracts. It’s vital that they are aware that prices on these contracts are on average 80 per cent more than rates charged in a negotiated contract.

If you are on a deemed contract you should shop around and compare supplier offers for a new energy contract, as you could make significant savings.

Knowing who your energy supplier is and what tariff you are on allows you to compare their tariffs with the rest of the market which prevents you from overpaying on your gas and electric.

So how can I find out who supplies my energy?

Most of the time, landlords, letting agents or previous owners will be able to tell you who your energy suppliers are.

Energy companies usually send letters addressed to ‘the Occupier’ if the previous occupants have informed them that they are moving out. The letter usually provides details of the current energy deal and who the current energy supplier is.

Sometime though, this information cannot be retrieved, and the previous residents didn’t inform their suppliers about their move. In this case, Ofgem advises the use of the services below to help find your energy suppliers.
