Wondering where your gas and electricity comes from? Here’s what you should know about your energy supply

How does the UK’s energy supply work?

Your supply of gas and electricity in the UK comes from your local distribution network. Across the UK there are eight gas distribution networks and 14 for electricity.

In many cases, the previous owner or tenant will have told the energy firm of their impending move. If so, the current supplier will probably send a letter addressed to The Occupier with all the relevant information.

How can I find out who supplies energy to my home?

There are a few ways you can find out who supplies gas and electricity to your home. The easiest way is to check your most recent energy bill, which will also give you details about the energy tariff you’re on.

But if you’ve just moved home, you might not have a recent energy bill for your property. If this is the case and you’re a tenant, you can try asking:

  • Your landlord
  • The previous tenants
  • The letting or estate agent

If you own your home, you could ask the previous owners or the estate agent.

Services for finding your gas and electricity supplier

If you don’t have a recent bill, or if you’ve had no luck asking any of the above, there are services you can use to find out where your gas and electricity is coming from.

Finding your gas supply

You can find your gas supplier by searching your postcode on the Meter Point Administration’s Find My Supplier tool, or you can call them directly on 0870 608 1524. Calling this number will cost 7p a minute on top of your standard rate.

If you call the Meter Point Administration you should also receive a Meter Point Reference Number, which could be useful if you need to talk to them again.

Switching energy provider

Whichever local distribution network is supplying your region, the gas and electricity stay the same. The only thing that changes when you switch is the provider – which is why you shouldn’t be paying over the odds for energy.

Switching to a new energy provider can help you save money on your energy bills – in fact, you could save at least £243* by switching through MoneySuperMarket.

How do I switch energy provider?

Comparing energy providers with MoneySuperMarket is the best way to find a cheaper deal for your gas and electricity supply. All you need to do is tell us a little about yourself, your home, and your energy usage – the more you can tell us about the energy you use, the more accurate your bills will be.

It can be useful to have a copy of your most recent energy bill to hand, as this can have important information about your current tariff.

We’ll then be able to show you a list of tariffs from a range of suppliers across the country, including the Big Six as well as smaller suppliers. You’ll be able to compare tariffs by the price you’ll pay for energy, and once you’ve found the deal you want just click through to the supplier to finalise your purchase.
