@anftewsloane56 The whd is closed for this year. You wil have to apply for next year on line if in broader group. You are only allowed one a year even if changing supplier. You have to be with your supplier on july for the core group. I found SP usually opens again about august/Sept time so look out for it then.
@KayPringle The WHD system for 2021/2022has not opened yet. Probably after September you can apply online giving details of the social benefits you receive. Once accepted you will get an email with a reference number. The actual credit is made on your electricity account after March 2022.
