It’s worthwhile pointing out that checking your gas supplier is easy to do online from a central site which covers the UK. Find My Supplier
Electricity suppliers are found by asking your regional Distribution Network Operator (DNO).
Once you know which DNO serves you, go to their website.
So for customers in one of the four regions supplied by Western Power, the relevant site address is here. For UK Power Networks (SE England) go to here.

Hi
We're fellow customers who have no access to any account details. I suggest you message the webchat team via the Help Centre, giving them the full postal address, the date you moved in and the current meter reading.
Please post back here again if you have difficulties.
I'm trying to find out if you supply the gas and electricity to the property I've moved Into?

Good afternoon 
Congratulations on your new home!
Probably the easiest way to find out would be to use the lookup tools provided by your local Distribution Network Operator for electricity, and Gas Transporter for gas. There’s details on how to do this over at Ofgem. Those tools should identify who the current supplier is.
What you’ll then want to do, is contact the current supplier and set up an account in your name. You’ll be asked for opening readings as well. If you’d like to stay with that supplier, feel free to pick a suitable tariff that takes your fancy. Otherwise, if you’d like to explore the market first, I’d recommend going with the Standard Variable tariff to begin with, so that you’re not locked in. It’s a bit more expensive but won’t be too bad if it’s temporary.
You can then choose your preferred supplier and go from there. If you’d like to go with OVO, you can find the switch tool over here. It may take a few weeks for any switch to go through. You won’t need to let the old supplier know - your new one will take care of that for you.
If you get stuck, feel free to let us know and we’ll be happy to help.
I think we might need to reassign the ‘best answer’ of this topic thread (

I think it might be worth updating this one Tim!
The existing answer only really works if the current supplier happens to be OVO, which sort of defeats the object of asking OVO whether OVO currently supplies a property. 
It’s probably best to use a lookup tool that is independent from all suppliers, but still has access to ECOES and Xoserve. It’s probably faster that way as well!

ANDDDDDDD I think we have a new winner 
Sorry for the back and forth on this best answer, still - it’s a common question for ANYONE moving into a new home and it deserves something involving as few steps as possible.
