For smart PAYG meters
If you’re eligible and have a smart PAYG meter, the WHD team will add this as a credit to your meter.
For traditional PAYG meters
If you have a Traditional PAYG electricity meter, you’ll receive a letter containing a barcoded ‘Energy Voucher’ from the Post Office. You’ll take the ‘Energy Voucher’, electric/gas key/card and suitable ID (as stated in their letter) to their nearest Post Office
Post Office Energy Vouchers remain valid for 90 days from the issue date on the letter before expiring.
Ok… So… Here’s the answer…
After digging even deeper and quite literally pulling some of my contacts out of bed (thanks, much appreciated!) I’ve figured it out.
You need to visit the Post Office because this year, these Vouchers are being issued as Post Office Energy Vouchers rather than using the Paypoint system of previous years. OVO isn’t the only supplier doing it this way. Going to Paypoint will NOT work this time around.
You need to do what the letter instructs you to do - if the postmaster messes up, you need to take it up with their manager rather than OVO as they’ve all been told to process these.
Any Post Office staff who either reject the voucher by redirecting you to Paypoint OR just giving you the cash aren’t following the proper process for Post Office Payout - they risk not getting reimbursed for it as well which could unbalance their books.
The Warm Home Discount (WHD) is a government scheme providing a one-off £150 discount on electricity bills for eligible households, including those on Pay As You Go (PAYG) with OVO Energy. The scheme is typically applied automatically between October and March, but those in Scotland on low incomes may need to apply. For PAYG customers, the discount is usually applied as credit to the meter, often via a voucher or remote token issue.

How the Warm Home Discount Works with OVO's PAYG Customers:

Automatic Discount:
Eligible PAYG customers with OVO Energy will typically have the £150 WHD credit applied directly to their meter, often as a remote token issue.

Voucher or Token:
For traditional PAYG meters (not smart meters), a voucher code may be provided, which can be used to top up the key or card, and the credit is then applied to the meter.
