You can see same results in https://dnschecker.org/#NS/aldharrab.co.uk . Is this a new domain ? You might have to contact AWS (if that is where you purchased this domain) and ask them why the nameservers have not propagated.
I've had this domain since April 2022, I did indeed purchase this domain from Route 53 (AWS) and will be contacting them shortly regarding this matter.
Well, thank god it told me I need to wait 360 seconds before responding to this message.
Apparently, I need to upgrade to get support on an issue on their end. I'll try to find some other way to contact technical support in the meantime
