If you don’t know who supplies your gas and electricity, you can find the name of your suppliers online.
If you know one company supplies both your gas and electricity, it’s easier to follow the instructions to check who your gas supplier is.
Find your gas supplier
To find out who supplies your gas you can either:
contact the Meter Number Helpline

Telephone: 0870 608 1524
Monday to Friday, 8:30am to 5pm
Calls cost 7p a minute, plus your phone company's access charge.
You can ask for your Meter Point Reference Number (MPRN). You might need this when you sign up to a new gas supplier.
Find your electricity supplier
To find your electricity supplier you first need to check who your network operator is. This is who owns and operates the cables in your area.
Check who your electricity network operator is on the Power Cut 105 website. You’ll need to know the postcode of the property.
If you get an error message, refresh the page and enter your postcode again.
When you know who your network operator is, visit their website to search for your electricity supplier. You can usually search using your property’s postcode, but some network operators might ask you to fill in a form.
