Sky says its email is not affected by Yahoo’s 15GB storage cut
Sky has told ISPreview that the new 15GB storage limit on Yahoo’s free UK email does not apply to Sky Yahoo Mail accounts, and that there are no plans to extend it to them. If a message from Yahoo earlier this year left you expecting your Sky inbox to shrink, it is not happening for now.
Yahoo cut free storage in the UK from 1TB to 15GB in May, and said it would enforce the new ceiling more strictly. Hit that ceiling on an ordinary Yahoo account and you stop being able to send or receive until you clear out old messages or pay to upgrade, with Yahoo Mail Plus offering 200GB for £4.99 a month. Sky’s email has run on a Yahoo platform since 2013. That is why the change looked like it would land on Sky customers too.
Why people thought it applied to them
Sky never issued a notice of its own. What its customers did get, early in 2026, was a general message direct from Yahoo that read as though they were included, and Sky’s own help forum filled up with people asking what it meant for their address. ISPreview says it spent more than a week chasing a clear answer. Sky eventually confirmed that Sky Yahoo Mail is out of scope, and that it is still working with Yahoo to support Sky Mail, a legacy service used by a small share of its customers.
What this means for you
In practice, nothing to do. Most people with a Sky address would not be anywhere near 15GB, although a long-standing account with years of attachments sitting in it is exactly the sort that could have been caught out. The reassurance has limits. Sky said there are no plans, which is not the same as a promise, and the company has published nothing about this itself. The only public record of it is what Sky told a trade site.
The wider lesson is one we keep coming back to. An address ending in the name of your broadband provider is not a perk, it is a string attached. Ofcom does not regulate email, so there is no complaints route when one changes under you, and no rule that lets you take the address with you when you leave. Virgin Media is closing its own email service and moving customers to a provider most of them had never heard of. Sky’s has survived this round, which is a reprieve rather than a reason to lean on it harder.
