Talktalk doesn't offer a social tariff as such, @Madmaz.
If you are receiving some benefits, you may qualify through the Jobcentre scheme:

Otherwise, all you can do is haggle when it is time to renew. Don't do it mid term, as the default is for Talktalk to charge £30 to fiddle with admin in the middle of a contract. In the last 2 to 3 months, give them a ring.
But home schooling doesn't add expense to the wifi you already have - it's there whether you use it or not, and it's not throttled so you can use it a lot.
Ultimately the contract you have is for ordinary residential use, despite working from home being much more prevalent these days.
