Hi ​@Linny70 ,

The limit is usually around £250 at any given time on the Key/Card, and £255 on the Meters.

However, unless you have Smart Meters it is NOT recommended to stuff the Key/Card and/or Meters full of that much credit because you have a high risk of loss if something happens.

Hey ​@Linny70,

Welcome to the OVO Online Community 

I can see Blastoise has already given some helpful advice here. I just wanted to add the following:
 

For Traditional meters, the electricity meter holds £250 maximum, and the most you top up in one transaction is £99. For gas traditional the maximum a meter holds is £999 and can top up up to £49 in one transaction.

For Smart a meters, for both gas and electricity, the meters hold up to £999 and maximum top up in one transaction is £200.

If you’re not sure Pay As You Go is right for you, and are interested in switching to pay monthly you can contact the Pay As You Go Support Team. You’ll be able to set up automatic monthly payments in the form of direct debits, make top up payments and won’t have to worry about going off supply.
