Have you tried a factory reset on the home hub?

What is "home protect", is that a BT extra?
Are BT parental controls active?
This issue reminds me of something which affected my internet access a few years ago. I could access most websites apart from a few prominent sites such as google.com. Those were blocked with an error message, don't recall the exact wording.
Eventually I realised it was my IP address which for some reason was on some sort of blacklist. The fix was simple for me, I powered down the hub and left it several minutes. Then powered it up, which resulted in allocation of a different IP address, everything was then ok.
But before taking any action, you might check whether this might be the problem using an online check such as:

There could be a data integrity issue, where your connection profile is linked to the wrong account, and is filtering your content.
Try the factory reset first, as that will cause a change of IP address.
Hello, thank you for the reply.
According to that website my IP address isn't listed on any of the black list databases.
BT are helping now, they have factory reset the hub but no change.
They have forwarded to the complaints team.
Thank you
It sound like your account is somehow linked to the wrong profile, which is blocking that site.
If you know how to change the DNS setting on your computer/laptop, then change them to 8.8.8.8 and 8.8.4.4, as they are Google DNS settings. That would prove whether its BT DNS which is causing the issue.
