Most ISPs will have early cancellation fees, @robkey.
Talktalk doesn't have deals that pay your early termination fees from another provider, though some of their voucher promises, if advertised at the time, may help mitigate the damage.
You were in contract with EE and signed up to their Ts&Cs, so sadly, if you move provider when still in contract there's a penalty. Only EE could waive some of it if you haggled with them, and they don't have to.
ISPs have costs to manage too, which is why the best deals come with strings attached.
